What are the features of children's eye-protecting desk lamps

Enjoy modern lighting and avoid the impact of poor lighting on human health. Experts suggest that when indoor lighting must be used, five principles of lighting should be followed:

1. Use extensive lighting, and the light should illuminate the entire desktop.

2. Use uniform lighting, and the illuminance of each part should be consistent.

3. Maintain stable lighting. The light source should not flicker or dim at times.

4. Ensure adequate lighting;

5. Finally, it is important to avoid direct exposure of ambient light to the eyes.

When using lamps, one should follow the common sense of healthy lighting: for instance, the illuminance for reading is closely related to age; the elderly need 15 times more illuminance than children.

Why do high-frequency eye-protecting lamps have electromagnetic radiation

To overcome the stroboscopic problem of 50hz fluorescent lamps, high-frequency eye-protecting lamps operate at frequencies ranging from 40,000 to 55,000Hz, which inevitably generates high-frequency power electromagnetic radiation. Environmental experts point out that excessive electromagnetic radiation may cause palpitations, insomnia, reduced white blood cells, memory loss, and even lead to a decline in immune function, as well as damage to the blood system and nervous system.

The damage caused by electromagnetic environment radiation is cumulative. The closer the distance and the lighter the weight, the greater the degree of damage. It has become a consensus to offer more protection and reduce risks.

Led is a semiconductor solid-state light-emitting device: it has the advantages of small size, light weight, high brightness, low energy consumption, long lifespan, high safety, high color purity, good directionality, low maintenance cost, and environmental friendliness without pollution.

Led lighting is a green light source: it has a low working voltage and consumes less electricity. Stable performance and long service life (generally 100,000 hours); Strong impact resistance and vibration resistance; led lighting products can provide a high-quality light environment, enhance the luminous efficiency of the lighting system, contain no infrared or ultraviolet components, have high color rendering and strong directionality of light emission. It has good dimming performance and will not cause visual errors when the color temperature changes. Cold light sources have low heat generation and can be touched safely. Improve glare and reduce and eliminate light pollution. Zero flicker, no eye fatigue. It has no electromagnetic radiation to prevent radiation pollution and protect the brain. It can not only provide a comfortable lighting space but also well meet people's physiological health needs. It is a healthy light source that protects eyesight and is environmentally friendly. Long-term use can protect eyesight and prevent myopia. Disadvantages: 1. High price; 2. There is still a considerable gap between the generally achievable light efficiency and the theoretical light efficiency. There is still a considerable gap between the achievable lifespan and the theoretical lifespan (100,000 hours). 4. It still has a certain amount of calorific value; 5. Light attenuation can also be significantly reduced.
