Intelligent eye-protection study lamp design companies believe that some families, in order to save electricity, only turn on a desk lamp for their children's studies. Sometimes, for fear of insufficient brightness, they will change to a higher-wattage lamp. If only the desk lamp is lit, either dimly or with very high illuminance under the lamp while the illuminance in the reading area is very low, the eyes must constantly adapt and adjust to the excessively high or low brightness contrast in the field of vision, easily leading to visual fatigue and myopia. Generally speaking, in addition to turning on the desk lamp, a relatively soft background lighting should also be provided to improve eyesight and reduce visual fatigue.

Intelligent eye-protection study lamp design companies believe that indoor lighting fixtures should avoid direct glare, and their uniform glare values should meet national standards. Some home decorations or the mirror-like reflections of materials such as metal or glass plates produce indirect glare, which can cause subjective reactions of visual discomfort, sometimes even making it difficult to see the details of the text in books. Some children, because of their young age or insensitivity to subjective reactions, are disturbed by glare for a long time, leading to a sharp decline in vision.

Intelligent eye-protection study lamp design companies believe that the characteristics of eye-protection lamps are:

1. Eye-protection lamps should have relatively uniform light distribution, and the recommended value for uniformity of illumination on the work surface is less than 3.0.

2. Eliminate direct glare. When observed at a height of 400 mm and a parallel distance of 600 mm from the eyes, the light source of the desk lamp is invisible. To protect the eyes from the desk lamp, lenses or grilles need to be set up to prevent glare caused by direct light. There is no need to expose the bulb.

3. Flicker-free. Intelligent eye-protection study lamp design companies believe that, according to the recommendations of the CIE international standard "Indoor Workplace Lighting Guide S800-2001," the flicker frequency of the desk lamp should be higher than 25000 rpm, but a desk lamp that meets the national EMI/EMC electromagnetic radiation detection standards should be selected.

4. High color rendering and appropriate color temperature. The color rendering index should be greater than 80%, and the color temperature of the desk lamp should be 3300 K ~ 5300 K. When purchasing, pay attention to the markings on the fluorescent tube: rr for daylight color, rn for warm white, which can protect the eyes; Rl is cool white, and rb is white, which has no eye-protection effect.

5. Ultraviolet (UV) filtration. Intelligent eye-protection study lamp design companies believe that most desk lamps currently use fluorescent bulbs, which produce ultraviolet light after long-term use and aging. Considering prolonged desk work, it would be better if the lampshade of the desk lamp were fitted with a UV filter membrane.

6. Reduce reflected glare. Intelligent eye-protection study lamp design companies believe that when reading characters on coated paper, a mirror-like glare often appears, known as reflected glare. The brightness of the reflected glare is very high, and after entering the eyes, it may damage the lens and retina, increasing the probability of myopia in adolescents and cataracts in the elderly in the long run. Adding a polarizing film to the desk lamp is a good solution. Pay attention to whether there is such a design when purchasing.

The above are some key points about eye-protection lamps. We hope that everyone can carefully learn and understand the relevant knowledge.
