LED is a point light source, different from the current market of energy-saving lamps or incandescent, point light as the name suggests is a point of light, and this point also has another important feature of the light, that is, only one side of the light , If we want to use this special light to do the use of lighting, then the light must be a certain treatment, then use the light guide plate, through the light guide plate, the LED light to refraction, this can To meet our requirements and purpose, although the LED in the optical point of view has a qualitative leap, but if the human eye directly to the light source, will cause some damage to our eyes, so in the LED lighting, we further light Was processed so that the human eye could be directly observed for the purpose while softening the light.
At present, the industry is widely used in a single 0.06W power, the maximum brightness can be done 7LM, we temporarily do 6LM calculation, if you want to power up to 1W, we need to use 17 the same LED, the total Brightness of 17 * 6 = 102LM, that can do 100LM / W; if we use a single chip for the 1W power, the output of the maximum brightness of 80LM, commonly used in the general about 60LM, which is the brightness of the A major difference, it can be seen, for the use of the family, we still have to choose a small power LED more appropriate. From the product cost point of view, high-power LED cost is higher than the cost of low-power, which comes from two aspects, one is the cost of LED itself, and second, high-power LED to aluminum heat sink, Circuit board, coupled with the natural heat can meet the requirements. From the future maintenance costs of the product point of view, if our lamps in the use of failure, you can find any electrical repair shop to replace the damaged LED, a 0.06W LED cost up to 0.8 yuan, plus maintenance costs do not exceed 4 Yuan, if it is to replace a 1W LED, LED cost will be 7 yuan, plus maintenance costs will be about 12 yuan Moreover, the small power LED just an electronic market can be purchased to the high-power is not necessarily where Can be bought.
With the continuous development of LED technology, people to adapt to large-scale lighting and research and development of high-power single LED chip, the world's most cutting-edge has been able to do a single LED power of 200W or more, although the power can be done, but Its cost is not good. LED lamp beads to high power is a market trend, but also the future development of the mainstream, but the current technology has not yet reached the desired results, from a technical point of view, the current high-power LED lighting is not suitable for Home lighting.
