(Summary description)1. Craft lamp

On the desks, coffee tables, bedside tables, and even corner cabinets and decorative shelves in the room, a beautifully shaped table lamp often has a unique effect. Its own unique effect adds a touch of bright color to the room.

Most craft desk lamps are composed of two parts: a lamp holder and a lampshade. The lamp holder is made of ceramics, stone, cloisonne, bamboo weaving, marble and other materials. Lampshades are usually made of glass, metal, plastic, fabric, bamboo and rattan. Once the lamp holder and lampshade are ingeniously matched, the table lamp becomes a beautiful work of art.

The craft table lamp does not emphasize the lighting function, and some craft table lamps even use colored glass diffuse lighting and gauze cover.

The appearance design of the craft table lamp is very important, emphasizing artistic modeling and decorative effects. The shape of the lamp holder is either an elegant vase style, or a kiosk and crown style, and some even use a novel telephone style.

The lampshade of the table lamp is intended to concentrate the light and increase the brightness. But for craft table lamps, the lampshade has also become a place for designers to show their talents. Some are designed in a dome-like shape, and some are designed in a straw hat shape. Each is really unique.

No matter what the article is, the lampshade and lamp holder must finally present the overall design effect. In addition, as the colors of table lamps become more abundant, consumers have more and more choices. At present, the colors of table lamps on the market are milky white, orange yellow, grass green, etc. You can choose table lamps of different styles and materials according to the room decoration style, so as to form a perfect match with other furnishings.

Nowadays, with the emergence of new light sources, a number of sculptural craft table lamps have appeared. This kind of craft table lamp, from the outside, is either a flower-arranged vase, or a cartoon villain or a mermaid. The light source is hidden inside.

2. Writing desk lamp

Original table lamp using a rotating model.

In the era of knowledge economy, every family member actually uses the writing table lamp to read and write. Therefore, it is necessary to use the writing table lamp as the main light source to set up a study room lighting environment.

The study lighting pays attention to the local lighting effect of the light. The lamps and lanterns mainly based on writing desk lamps should pay attention to their appearance under the premise of considering their brightness. Their shapes and colors should be elegant and beautiful, suitable for the calm and elegant learning environment of the study.

Studies have shown that when the surface illumination of the viewed object reaches 1000 lux, the human eye sees things most clearly and most comfortably. Whether the writing desk lamp can increase the illuminance of the desktop to this standard, I am afraid it is the focus of consideration when purchasing.

At present, the light sources used in writing desk lamps on the market are mainly incandescent lamps, quartz halogen lamps and eye protection lamps. Incandescent lamps mostly use bulbs that consume 40W-60W as the light source. They do not need ballasts and are cheap. The price gap is mainly reflected in the craftsmanship of the lamp housing. However, incandescent lamps consume a lot of power, have high surface temperature, have stroboscopic, and illuminate. Low light, short life of the bulb, and the bulb is a spherical point light source, it is difficult to form a large uniform high illuminance area, so in developed countries abroad, it is no longer used as a writing lighting, but only used as a decorative lamp for craftsmanship.

Quartz halogen lamps mostly use 30W-50W halogen bulbs as the light source, and need a ballast. The price is slightly more expensive than that of incandescent lamps. The illuminance is nearly 50% higher than that of incandescent lamps of the same wattage. The lamps are made very compact, and the shape is more avant-garde. However, the surface of this small halogen light source is hot, the light is dazzling, and it can cause burns when touched, so it must be protected by a cover. In addition, this kind of lamp is a typical point light source, with great changes in brightness and darkness in the near and far, and it is difficult to form a large enough high illuminance area on the desktop.

One of the major appearance features of the writing desk lamp is that it has a reflector, an opening at the bottom, and a direct-shooting style. The current writing desk lamps on the market include metal serpentine tube work desk lamps, clip-on spring rocker suspended desk lamps, seat dimmable all-plastic desk lamps, seat dimmable enamel desk lamps, and copper seat classic single and double enamel covers.

Table lamps, trough-shaped table lamps with double porcelain and two-color shades, classical candle table lamps, ancient kerosene lamp table lamps, and double-capped glass table lamps.

The design of the new writing desk lamp pays more attention to convenience and practicality. There are combinations of alarm clocks and desk lamps, the combination of miniature fans and desk lamps, and the combination of pen holders, stationery boxes and desk lamps.

The lampshades of writing desk lamps are generally opaque or semi-transparent, so that the light is concentrated. The distance between its luminosity and the line of sight of people is regulated, generally 30 cm to 45 cm apart, and the light forms an angle of 45 degrees with the line of sight.

If the writing desk lamp is dedicated to readers, in addition to the brightness, it is necessary to avoid flickering. The alternating current light source used daily, due to the constant change of the voltage, often has the phenomenon of light and dark alternation, this kind of light flicker phenomenon is called stroboscopic. Strobe flash is less than 100 times per second, which is a low frequency flash, which has strong irritation and damage to human eyes. Reading and working under this light source for a long time will cause young people to have dry eyes, eye pain and eye fatigue. Easy to cause myopia.

At present, there is a flicker-free vision health care desk lamp on the market, which converts ordinary alternating current signals into high-frequency signals through electronic processing, so that people's eyes can not feel the flicker phenomenon, which is very beneficial to protect eyesight.

Experts remind parents that when choosing lamps for students, they can bring a small top with them and spin the top under the light. If there is no inverted visual illusion, it means that the lamp does not flicker.

How to maintain charging led table lamp [ 2021-11-22 ]

The lamps are not cleaned, not only affect the lighting, but also affect the mood and even health. However, many people’s lamps are cleaned only once every few years because they find it too troublesome and easy to damage. The maintenance of the rechargeable LED desk lamp lies in the battery. Because ordinary LED lights will not break too quickly. Battery maintenance also depends on what type of battery you have. Lead-acid batteries are now more widely available in the market. The most important thing in the maintenance of this kind of battery is that it cannot be over-discharged, that is, it cannot be used dry, and it must be recharged after the lamp is obviously dimmed. Pay attention to the calculation time when charging, because generally the charging time is relatively long (10 hours), and the power must be cut off in time when it is full. If you don’t use it for a long time, it is recommended to charge it once in 2.3 months.

What is the difference between cold white light and warm white light? [ 2021-11-22 ]

Difference 1: Different color temperature values. The color temperature of cool white light is 5500-7500K, and the color temperature of warm white light is between 3000-3500K. The lower the color temperature, the more yellow the lamp color; the higher the color temperature, the whiter the lamp color. Difference 2: The degree of color reproduction is different. Cool white light is very bright, with high color reproduction, suitable for use in exhibition halls, kitchens and other environments with operating spaces. The warm white light looks dim and has low color reproduction, which can create a sense of atmosphere and is suitable for bedrooms, coffee shops, etc. How to choose the color temperature of the light 1. Use environment To choose the color temperature value of the light, we must first consider what the requirements of the use environment are. Generally, the color temperature value of the light can be divided into three categories: cold white light, positive white light and warm white light. The color temperature of cold white light is often between 5500K-7500K, and the color reproduction is high but very dazzling, and it is more suitable for use in exhibition halls and other places. It is almost unsuitable to use cool white in the home. Of course, the kitchen is an exception. After all, this area needs to concentrate on fine operations, and high color temperature light sources are more suitable. As for other areas of the home, it is recommended to choose 2700K, 3000K or 4000K warm white light or positive white light according to hobbies and needs. For example, the living room, porch, study and other areas still have a certain demand for light, so the 4000K light source is more suitable. For areas like the bedroom, you can choose warm white light. After all, the light color will affect people's desire to fall asleep, right? 2. Home tone On the other hand, the choice of light color temperature can also refer to the color of the home. For example, if the wall is painted with color, then the light source of about 4000K will not make people dazzling, but can also restore the color of the color itself to the greatest extent. And if the home is basically solid wood furniture, then furniture made of black walnut, cherry, white oak and other materials can better reflect its texture and color with a warm white lamp of about 3000K.

What is the national standard for reading and writing desk lamps [ 2021-11-22 ]

At present, there are three main national standards related to reading and writing desk lamps: GB 7000.204-2008 Lamps Part 2-2: Special Requirements Recessed Lamps GB 7000.1-2015 Lamps Part 1: General requirements and tests. GB/T 9473-2017 performance requirements for reading and writing desk lamps Among the above three standards, GB 7000.204 and GB 7000.1 are safety standards for table lamps, which stipulate the most basic electrical and mechanical safety requirements. GB/T 9473 is the performance standard for reading and writing table lamps, which stipulates the comfort of reading and writing table lamps and the impact on the human body. And the most basic photoelectric performance requirements. As early as 2008, my country formulated the performance requirements standard for reading and writing table lamps GB/T 9473 "Performance requirements for reading and writing table lamps", which stipulated key indicators related to lighting comfort. This standard is recommended. Receive attention. With the rapid development of semiconductor lighting technology and the gradual maturity of technology, LED table lamps have become the mainstream of the market in recent years. The relevant standard committee organized the revision of GB/T 9473-2008. Table lamps are included in the scope of the standard, and new indicators such as light, electromagnetic radiation, flicker, and other indicators of consumer concern have been added.

Does the table lamp cause my child's eyes to be myopia? [ 2021-11-22 ]

Before choosing a table lamp, let’s first understand our country’s national standards. On the market, any table lamp that dares to claim "eye protection", "comfort", and "study and work use" should have its performance parameters within the scope of the GB/T 9473 standard specification. It must meet the performance requirements stipulated by the standard, otherwise it is false propaganda. The performance parameters mentioned here mainly include the uniformity of illuminance intensity, shading, color temperature and blue light hazard of the retina. If you want to know more about the specific content of the specification, you can check the relevant information given below. Next, we will understand from these dimensions, what kind of quality a qualified eye protection table lamp has. Ps: (National Standard GB/T 9473-2017 "Performance Requirements for Reading and Writing Table Lamps" was formulated by the National Shanghai Institute of Product Quality Supervision and Inspection. It was approved for publication on September 30, 2017 and officially implemented on April 1, 2018. Replace the original GB/T 9473-2008 standard.) 1. Illumination intensity and uniformity We must first figure out what is illuminance? Sufficient illuminance can ensure that the eyes have a good degree of recognition of the target. The simple understanding is that the brightness must be appropriate, not too dark or too bright, so it seems that it is quite difficult to accurately determine this degree! Then you might as well take the brightness of the natural light source around 10 o'clock in the morning as a reference. In any case, it is enough to ensure that our eyes see things easily under this light source. The so-called effortlessness means that the eyes can see clearly without large-scale adjustment of pupil muscles. Camera friends should understand that when the light is dim, to ensure correct exposure, you need to increase the aperture to increase the amount of light in the case of the same time. On the contrary, reduce the aperture to reduce the amount of light. Eyes are similar to cameras. They rely on adjusting the size of their pupils to achieve "adjustment of the aperture" on the camera to increase or decrease the amount of light entering. Of course, it is not enough to satisfy the requirement of sufficient light, but also to consider whether the light is uniform. If the light is uneven, it will cause the eyes to constantly adjust themselves in different light and dark areas, which will quickly cause fatigue and cause eye discomfort in a short time. Therefore, illuminance intensity and uniformity are two important indicators of constant visual comfort. If you want more specific standards and regulations, please refer to the following four points: In the central area and edge area of reading and writing, the illuminance and uniformity of the lamps must be at least Class A, preferably Class AA; A-level illumination requires at least 300lx in the central area and 150lx at the edge; AA-level illuminance requires at least 500lx in the central area and 250lx at the edge; The requirements for uniformity of illuminance (the ratio of the maximum value to the minimum value) of A-level and AA-level are not more than 3. (Lx is the international unit of illuminance, which is the abbreviation of lux in English, and its physical meaning is the luminous flux irradiated on a unit area) 2. Shading The shading can be understood only literally. For example, in the process of using a desk lamp, if we get tired in a posture, stretch our waist, raise our head and move our neck, our eyes will inevitably touch the outer lampshade of the lamp. If the lampshade is opaque, the brightness contrast will be produced. It will make our eyes uncomfortable; if the light transmittance of the lampshade is too good, its brightness is much greater than the brightness of the paper, and it will also feel uncomfortable to the eyes. Therefore, the right light transmission can make our eyes more comfortable. Therefore, the lampshade of a comfortable desk lamp must have a certain degree of shading, and when we are in a working sitting position, the surface brightness of the light-emitting part that can be seen up to the head cannot be higher than 2000cd per square meter, which is considered a qualified protection. The light-shielding property of the table lamp. (Cd is the international unit of luminous intensity, which is the abbreviation of candela in English, called candela, and its physical meaning is the size of the luminous flux transmitted by the light source in a solid angle in a certain direction) Three, color temperature Regarding color temperature, I think everyone is more familiar with "warm light" and "cold light". The color temperature of the light source determines the color of the light and also brings us different feelings. When the color temperature is less than 3000K, the light color is white and red. Warm feeling; when the color temperat

The correct use of table lamps [ 2021-11-22 ]

The light source should be located at the front left, and the light should not directly hit the eyes. Fluorescent lamps can be used for indoor lighting, and incandescent lamps can be used for desktop lighting. The brightness of the lighting cannot be too dim or too bright. The lamp power must not exceed 60 watts. Cannot use paper to make the lampshade. Keep away from combustible materials. 1.

The lamp power shall not exceed 60 watts. 5. Cannot use paper to make the lampshade. 6. Keep away from combustible materials. Table lamp, generally refers to the electric lamp with a base used on the table, but with the advancement of technology, the appearance and shape of the table lamp are also constantly evolving, and gradually there is a magnetic table lamp that can be adsorbed at any position. Its compactness Exquisite and easy to carry. The main function of the table lamp is to illuminate, which is convenient for reading, studying, working, etc. The table lamp has far surpassed its own value and has even become a work of art.

Precautions for choosing eye protection lamp [ 2021-11-22 ]

Now many of our parents are very concerned about their children's eyesight, for fear that their children are nearsighted, farsighted, amblyopic and so on. For parents, it is very important to choose suitable desks and chairs for their children and protect the lamps and lanterns to protect their eyes during the critical period when their children are under the pressure of reading! So what aspects should be paid to make a choice to protect children’s eyesight when buying a table lamp for children to read and do their homework? 　　The first is the appropriate illuminance 　　According to the "Japanese Lighting Manual" recommendation, the illuminance of the desk work surface is 300~750lx (lux). Too bright light will make the pupils too late to control and enter the eyes directly, which may damage the lens and retina; too dark light will keep the ciliary muscle in a state of tension, and continuous tension may cause myopia and high intraocular pressure diseases. In the case of energy-saving lamps, the appropriate range is between 11W and 18W, depending on personal comfort. Precautions for choosing eye protection lamp 　　 The second is uniform light distribution 　　 According to the national standard "Performance Requirements for Reading and Writing Table Lamps" (GBT9743-2008), the recommended value of working surface uniformity is less than 3.0. If the brightness of the working surface is uneven, the eyes will always switch between light and dark, and the ciliary muscles sometimes relax and become tense, and are always in motion; when the fatigue of the ciliary muscles cannot be restored, it will cause myopia, high intraocular pressure and other diseases . Precautions for choosing eye protection lamp 　　 Third to remove direct glare 　　 The sudden glare in the eyes may damage the retina and cause temporary blindness. According to the national standard "Performance Requirements for Reading and Writing Table Lamps" (GBT9743-2008), it is recommended that the light source of the table lamp cannot be seen when the eye height is 400mm and the parallel distance is 600mm. Therefore, the desk lamp that really considers eye protection needs to be equipped with anti-glare measures such as lens, grille, etc., to prevent direct light from forming glare, and the light bulb must not be exposed. Precautions for choosing eye protection lamp 　　 The fourth no flicker 　　 When the eyes can detect stroboscopic flicker, the ciliary muscles sometimes relax and become tense, and are always in motion; when the ciliary muscles cannot recover from fatigue, it can cause diseases such as myopia and high intraocular pressure. According to the CIE international standard "Indoor Workplace Lighting Guide S800-2001", the strobe frequency of the desk lamp should be higher than 25000rpm. But be aware that high-frequency electronic ballasts can cause electromagnetic radiation and electromagnetic pollution, so you should choose a table lamp that meets the national EMI/EMC electromagnetic radiation test. Precautions for choosing eye protection lamp 　　The fifth highest color rendering 　　 Many light sources will cast the color of the object. If the color cast is serious, it will cause a lot of adverse effects on the eyes for a long time. Therefore, a reasonable light source must have a strong color reproduction rate. According to the CIE international standard "Indoor Workplace Lighting Guide S800-2001", the color rendering of table lamps should be greater than 80%. Pay attention to the signs on the fluorescent tube when purchasing: rr is daylight color, rn is warm white, these two colors can protect the eyes; while rl is cool white, rb is white, and there is no eye protection. 　　The sixth color temperature close to natural light 　　According to the CIE international standard "Indoor Workplace Lighting Guide S800-2001", it is recommended that the color temperature of the table lamp is 3300K~5300K. If you read books under high color temperature or low color temperature light for a long time, the light waves received by your eyes are not enough, only part of the light waves in the spectrum; high color temperature light waves will make the eye muscles in a state of excitement, easy to fatigue, resulting in eye fatigue, high intraocular pressure, Diseases such as myopia; low color temperature light will keep the eyes in a relaxed state, which is not conducive to the development of eye muscles and forms diseases such as amblyopia. Precautions for choosing eye protection lamp 　　 Seventh UV filter 　　 At present, most desk lamps use fluorescent bulbs, which will produce ultraviolet rays after long-term use and aging. The accumulated UV intensity can cause the aging of the eyeball and cause eye diseases. Considering the long-term writing at the desk, the lampshade of the desk lamp is more effective if it has an ultraviolet filter film. Precautions for choosing eye protection lamp 　　 Eighth reduction of reflected glare 　　 When reading coated paper, there

What are the benefits of LED lights [ 2021-11-22 ]

Low wattage, high lumen The first thing you should consider is how to save electricity and reduce electricity bills. If the lumen of the lamp is high, the light is also brighter. Compared with incandescent bulbs, LED bulbs can provide a lot of lumens with just a few watts. Therefore, you need to find a low-wattage, high-lumen light bulb, because it can save electricity bills. On average, a 12-watt LED bulb can provide the same amount of light as a 60-watt incandescent bulb. This means you can save a lot of electricity, thereby saving electricity bills. Service life Second, what you should consider is the service life of LED bulbs. If used for three hours a day in a year, most LED bulbs can provide 25,000 to 50,000 hours of light. Color and color rendering index The third thing you should consider is the color of the LED bulb. One advantage of LEDs is that the light can be adjusted to the full spectrum. LED lights can be red, yellow, green, blue, warm white and cool white. The lower the color temperature, that is, the lower the Kelvin, the more yellow the white light. If the color temperature is higher, a bluish tint will appear. If you want warm colors, look for LEDs of about 2700K. At 3000K, the light is more like a halogen lamp. If you want cool white light, you need to look for 3500K to 4100K bulbs. The 5000K to 6500K bulbs imitate natural light or daylight. Another aspect of color is the color rendering index (CRI), which reflects the accuracy of the color under light. The higher the color rendering index, the more objects the LED bulb will light up. Spread of light The LED bulb emits light in a specific direction. So it is important to find out the angle at which the LED bulb spreads. The propagation of light is called the beam angle. The beam angles of LED bulbs on the market are 15, 30, 45, 60, and 100, while 120 and 180 are rare. The beam angle is less than 30, can be used as a spotlight, and its brightness or lumens per watt is the highest. Most of them have wattage less than 5, which is especially suitable for shops and places that need to highlight specific areas.

What are the types of table lamps [ 2021-11-22 ]

1. Craft lamp On the desks, coffee tables, bedside tables, and even corner cabinets and decorative shelves in the room, a beautifully shaped table lamp often has a unique effect. Its own unique effect adds a touch of bright color to the room. Most craft desk lamps are composed of two parts: a lamp holder and a lampshade. The lamp holder is made of ceramics, stone, cloisonne, bamboo weaving, marble and other materials. Lampshades are usually made of glass, metal, plastic, fabric, bamboo and rattan. Once the lamp holder and lampshade are ingeniously matched, the table lamp becomes a beautiful work of art. The craft table lamp does not emphasize the lighting function, and some craft table lamps even use colored glass diffuse lighting and gauze cover. The appearance design of the craft table lamp is very important, emphasizing artistic modeling and decorative effects. The shape of the lamp holder is either an elegant vase style, or a kiosk and crown style, and some even use a novel telephone style. The lampshade of the table lamp is intended to concentrate the light and increase the brightness. But for craft table lamps, the lampshade has also become a place for designers to show their talents. Some are designed in a dome-like shape, and some are designed in a straw hat shape. Each is really unique. No matter what the article is, the lampshade and lamp holder must finally present the overall design effect. In addition, as the colors of table lamps become more abundant, consumers have more and more choices. At present, the colors of table lamps on the market are milky white, orange yellow, grass green, etc. You can choose table lamps of different styles and materials according to the room decoration style, so as to form a perfect match with other furnishings. Nowadays, with the emergence of new light sources, a number of sculptural craft table lamps have appeared. This kind of craft table lamp, from the outside, is either a flower-arranged vase, or a cartoon villain or a mermaid. The light source is hidden inside. 2. Writing desk lamp Original table lamp using a rotating model. In the era of knowledge economy, every family member actually uses the writing table lamp to read and write. Therefore, it is necessary to use the writing table lamp as the main light source to set up a study room lighting environment. The study lighting pays attention to the local lighting effect of the light. The lamps and lanterns mainly based on writing desk lamps should pay attention to their appearance under the premise of considering their brightness. Their shapes and colors should be elegant and beautiful, suitable for the calm and elegant learning environment of the study. Studies have shown that when the surface illumination of the viewed object reaches 1000 lux, the human eye sees things most clearly and most comfortably. Whether the writing desk lamp can increase the illuminance of the desktop to this standard, I am afraid it is the focus of consideration when purchasing. At present, the light sources used in writing desk lamps on the market are mainly incandescent lamps, quartz halogen lamps and eye protection lamps. Incandescent lamps mostly use bulbs that consume 40W-60W as the light source. They do not need ballasts and are cheap. The price gap is mainly reflected in the craftsmanship of the lamp housing. However, incandescent lamps consume a lot of power, have high surface temperature, have stroboscopic, and illuminate. Low light, short life of the bulb, and the bulb is a spherical point light source, it is difficult to form a large uniform high illuminance area, so in developed countries abroad, it is no longer used as a writing lighting, but only used as a decorative lamp for craftsmanship. Quartz halogen lamps mostly use 30W-50W halogen bulbs as the light source, and need a ballast. The price is slightly more expensive than that of incandescent lamps. The illuminance is nearly 50% higher than that of incandescent lamps of the same wattage. The lamps are made very compact, and the shape is more avant-garde. However, the surface of this small halogen light source is hot, the light is dazzling, and it can cause burns when touched, so it must be protected by a cover. In addition, this kind of lamp is a typical point light source, with great changes in brightness and darkness in the near and far, and it is difficult to form a large enough high illuminance area on the desktop. One of the major appearance features of the writing desk lamp is that it has a reflector, an opening at the bottom, and a direct-shooting style.
