     (1) LED light source color temperature: the absolute temperature and the temperature of the light is equal or close to full radiator describes the light source color (see direct observation of the human eye color light source) is also called the color temperature of the light. The color temperature is expressed at an absolute temperature K. Different color temperatures cause people to react differently to their emotions. We generally divide the color temperature of light sources into three categories:
     A.: warm light warm light color temperature below 3300K. Warm light and incandescent lamp light color similar, more red components, gives a warm, healthy, comfortable, suitable for families, homes, hostels, hospitals, hotels and other places, low temperature or place.
     B. warm white: also called intermediate color, its color temperature in the 3300K5300K. The warm white light is soft and pleasant, comfortable and serene. It is suitable for shops, hospitals, offices, restaurants, restaurants, waiting rooms, etc..
    C. cold light: also called daylight, its color temperature is above 5300K, the light source is close to natural light, a bright feeling, the concentration of energy, suitable for offices, classrooms, conference room, drawing room, room design, library reading room, window display and other places.
     Color: the source of the object color is called the degree of color rendering, color is vivid, play light high color to color the better performance, we see the color of it is close to the natural color, light color play low on the color of the poor performance of the color deviation of I we also see more.
     Why color difference? The key lies in the light of characteristics of light, visible light wavelength in the range of 380nm to 780nm within the scope of that we see in the spectrum of red, orange, yellow, green, green, blue, purple, light emitted from the light source if the the proportion of light and natural light is similar, we see the color is more vivid.
     We usually use the color rendering index to characterize the color rendering. The standard color is radiated by a standard light source, and the color index is set at 100. When the color mark is irradiated by the test light source, the visual distortion of the color is the color index of the light source. The greater the color rendering index, the less distortion, otherwise, the greater the distortion, the smaller the color rendering index. Different places have different color index requirements for light sources. In the International Lighting Association, the color rendering index is generally divided into five categories:http://www.outedsionbulb.com/
LED lamp category applicable range
1A, >90, art galleries, museums and printing industries and places
2B 80 - 90 family, restaurant, advanced textile technology and similar industries
260 - 80 office, school, outdoor street lighting
340 - 60 heavy industrial factory, outdoor street lighting
420 - 40 outdoor road lighting and some less demanding places
