LED lighting technology standards

　　In China , there are a lot of manufacturers are making design and manufacturing LED lamps , but due to technical level is not uniform, resulting in uneven product quality , let's look at the basic technology of LED lighting standards .

　　1 , led light : LED lamps must use high brightness and high luminous efficiency low-light decline led chip package , which would choose to use formal channels chip package led lamp beads, gold wire package / phosphor / plastic insulation and so need to comply with LED lamps require materials .

　　2, LED lighting drive power : led light energy is converted DC electronic semiconductor components , so the driver needs to have a stable supply of high-performance driver chips , also need power factor compensation function only ensure the power efficiency , power to the entire fixture play a crucial factor , a good drive power is not only to ensure the stable DC confessed , but also fully guarantee the conversion efficiency , this parameter is embodied in real energy saving lamps and the grid is not wasted.

　　3,  Compact cooling system, an excellent addition to the appearance of high-grade appearance LED lamps , high-quality light and power , but also more importantly, the structure of the housing rationality , which involves cooling problems led lamps , led conversion of light energy due there are also a part of the electrical energy into heat energy , the need to heat leads into the atmosphere , so as to ensure stable led light , led lamp temperature is too high will cause the light fades faster, the led lamp life impact. It is worth mentioning that led chip technology continues to improve, the conversion efficiency is also improved , transforming heat energy consumption will be less, radiator parts will use thinner, but the heat is still present case must focus on study parameters.

　　4, LED lamps lens are usually ignored by some designers , in fact, the lens of the lens is also a profound impact on the final output rate of the flux , the current relatively good light transmission rate of up to 93 or more lens , the lens is more important cost , therefore, some of the plant in order to save costs while some use inexpensive lens material is definitely secondary materials , light transmission rate of 70 or so, with the naked eye can not see how to deceive consumers, but in fact, it is easy to test it out with the instrument result , the material is rather poor lens , with a long time will be yellow and other undesirable results.
