The light source characteristics of LED table light

★ Enjoy modern lighting, avoid adverse lighting effects on human health. Experts suggest that when you must use indoor lighting, lighting should be a good grasp of the five principles:
1, using a wide range of lighting, the light should be irradiated to the entire desktop;
2, the uniform illumination, illumination of each part must be consistent;
3, stable lighting, light not too bright or flashing;
4, to maintain adequate lighting;
5 Finally, be careful not light direct to the eye.

★when use illuminated light, you should have a healthy common sense: For example, the best read illumination has a great relationship with age, illumination that elderly need is 15 times than that for the child.

★ Eye high-frequency electromagnetic radiation:
To overcome the flicker 50 Hz fluorescent lights that use 40,000 ~ 55,000 Hz frequency, the high frequency eye protect LED table light is inevitably will bring the power of high frequency electromagnetic radiation. Environmental experts point out that excessive electromagnetic radiation can cause heart palpitations, insomnia, leukopenia, memory loss, and even cause immune function, cardiovascular system, and nervous system damage.
Electromagnetic radiation damage is cumulative, the closer, the lighter weight, the greater the damage subject is. A little more protection, curbing the risk has become a consensus.


★ LED lighting is a green light: low voltage, low power consumption; stable performance, long life (typically 100,000 hours); strong anti-shock and anti-vibration; LED lighting products can provide high-quality light environment, improve efficiency lighting systems, there is no infrared and ultraviolet components, high color and has a strong directional light; good dimming performance, no visual error when the color temperature changes; cold light source, low heat, safe to touch; improve glare, reduce and eliminate light pollution. There are zero flicker, does not make eye fatigue phenomenon. No electromagnetic radiation, to prevent radioactive contamination to protect the brain. It can provide a comfortable space for illumination, but also meet people's physical health needs, which is environmentally healthy light. For a long-term use, it can protect eyesight and prevent myopia.
Disadvantages:
1, expensive.
2, there is a great gap between the theoretical optical efficiency and actual photosynthetic efficiency.
3, there is a big gap between the theory use life (10w hours) and actually life.
4, there are still some heat.
5, the light fades can be greatly reduced. anty881209wong 140509
