15 kinds of special advantages for the simplified LED:

Energy saving, environmental protection, safety, long service life and low consumption, low heat, colored light, white light, high brightness, waterproof, miniature, shockproof, easy to adjust the light, beam concentrated, simple maintenance.

LED lighting features:

  1. Energy saving.
  2. Dc power supply, no stroboscopic.
  3. Solid light source, strong and durable.
  4. Not contain mercury, no pollution. No ultraviolet radiation.
  5. Good, the light energy efficiency is high directivity.
  6. Safety. Low voltage power supply, prevent to get an electric shock protection level for Ⅲ class.
  7. Cold start, no preheating, instantly start again, short response time.

There are usually white LED (color temperature 6500K or so),the neutral white light (color temperature around 4000K), warm white (color temperature of 3000K or less) of several types of light and color, what's the significance that we choose them? It should be referred to the colour rendering index, If the color rendering index of sunlight is 100%, then the high-quality white LED is generally about 75% (high color temperature is relatively low color rendering index), and the high-quality neutral white light and warm light LED can push color rendering index increased to 80%.

In outdoor,high brightness can judge the outline of the objects,but details and levels need a good color rendering index to support,that is to say in order to see the outline of the object clearly, it only needs to see the brightness,whether 100% color rendering of heat source, or the single-light with no color rendering index,it is the same if they are consistent with the brightness.And if you want to judge the object's color, detail, and level,75% visible light spectrum need 135% light strengthen to display the full color textures of the light 2.75% of the source of the light color rendering need higher (don't consider visual disturbances and adapt to the words about 135%) brightness to reach 100% of the light source show color details effect.Therefore, we always hope to get better color rendering index.

The principle of white LED light is:the electronic through a chip to emit blue light,and then stimulate yellow phosphor to emit yellow light, mixed into the white light,here the color rendering index of the yellow phosphor is relatively high,while the blue light is single-color light.so it is necessary to increase the proportion of yellow to improving the color rendering index.From this perspective,the more warm light color,better color rendering index, more suitable for outdoor sports.Again, the temperature of the warm color light is low, the wavelengths is longer, the penetrating in rain and fog weather is stronger and further,these characteristics together determine that outdoor sports need warm color LED light.

On the other hand,fluorescence excitation efficiency is relatively low, the overall brightness of warm white LED will be much lower, and at the same time ,the light colors appear to be dim,it just like the low-power incandescent light objects to be stained.On the whole,outdoors movement in the white LED product selection is more appropriate, not only with good color and penetration, but also to avoid a serious decrease in brightness and coloring phenomenon.
