Interpretation of LED lighting color temperature indicators: take you out of the lighting errors

With the continuous improvement of the industry as well as the deepening of the forbidden Bering, LED lighting products have begun to enter thousands of households. In recent years, the concept of intelligent lighting gradually into the public view, many manufacturers have launched their own smart lighting products. But as consumers in general, we know how much LED lighting products? How much do you know about intelligent lighting?

In fact, for ordinary consumers, many people in the understanding of lighting products still remain in the stage of incandescent lamp, lamp power and focus only on the brightness, LED lighting and intelligent lighting in this era is not enough. With the popularity of LED lighting products, health, comfort, safety and other issues should be concerned.

LED lighting products and the traditional incandescent lamp is essentially different from the principle of light. The incandescent lamp is thermal radiation, which belongs to the heat source, the temperature is relatively simple, basic is about 2800K; while LED is electroluminescence, belongs to a cold light source, the color is diverse, with the LED chip itself changes, white LED products from 2400K-6500K. So the question is, what kind of color temperature is more suitable for us? Due to cultural differences, Westerners love color temperature low 2700K-3000K products at home, so it looks very warm, very romantic; and Chinese generally love bright and clean about 5000K-6500K high temperature products, this environment is very spiritual, energetic. So what kind of color temperature segment more scientific, more conducive to human health?

It is understood that the lower the color temperature of the lighting products are relatively safe and healthy. From the light emitting principle of white light LED, the current mainstream packaging factory is the use of blue chip plus yellow green phosphor, the use of blue light to stimulate the yellow green phosphor and light emitting blue chip itself to produce white light. Color temperature is determined by the composition of the blue and yellow green light, the higher the blue light component, the higher the color temperature; the lower the blue light component, the lower the color temperature. So the color temperature is actually controlled by the proportion of blue light. Due to the short wavelength of blue light, easy to cause damage to the human eye. At present, the market appears on the eye protection lamp, the principle is to change the proportion of blue light from the light source, from the driver to eliminate the stroboscopic light source to achieve the purpose of eye protection.
