Analysis of the characteristics of children's eye protection desk lamp

I. Features of the children's eye protection table lamp

Enjoy modern lighting and avoid the effects of poor lighting on human health. Experts suggest that when indoor lighting must be used, 5 principles of lighting should be grasped.

1. use extensive lighting, where the light should illuminate the entire tabletop.

2. use uniform lighting, where the illumination level of each part is consistent.

3, maintain stable lighting, the light source should not be dark at times or flicker.

4, to maintain adequate lighting, brightness to meet the work and study, to relieve eye fatigue.

5. Finally, care needs to be taken not to let the light shine directly into the eyes.

When using desk lamps and lanterns, common sense should be used for healthy lighting: for example, the illumination level for reading is very much related to age, with older people needing 15 times more illumination than children.

Ⅱ. why do high frequency eye protection table lamps have electromagnetic radiation?

In order to overcome the problem of 50Hz fluorescent lamp strobe, high-frequency eye-care lamps use a frequency of 40,000 to 55,000Hz, which inevitably generates electromagnetic radiation from high-frequency power. According to environmental experts, excessive electromagnetic radiation may cause palpitations, insomnia, white blood cell reduction, memory loss, and can even lead to reduced immune function and damage to the blood and nervous systems.

The damage caused by electromagnetic environmental radiation is cumulative; the closer you are and the lighter you are, the greater the degree of damage you suffer from it. It has become a consensus to protect more and reduce the danger.

Led is a semiconductor solid light-emitting device: small size, light weight, high brightness, low energy consumption, long life, high security, high colour purity, good directionality, low maintenance costs, environmental protection and non-pollution advantages.

Led lighting is a green light source: low operating voltage, low power consumption; stable performance, long life (generally 100,000 hours); impact resistance, strong resistance to vibration; led lighting products can provide a high quality light environment, improve the lighting system's light efficiency, no infrared and ultraviolet components, high colour rendering and has a strong luminous directionality; good dimming performance, colour temperature changes will not produce visual errors; cold light source generates low heat, can be safe. The cold light source has low heat generation and is safe to touch; improves glare and reduces and eliminates light pollution.

Table lamp with zero strobe, does not cause eye fatigue. No electromagnetic radiation to prevent radiation pollution and protect the brain. It provides a comfortable light space, but also well meets the physiological health needs of people, is a healthy light source that protects vision and is environmentally friendly. Long-term use protects the eyesight and prevents myopia.
