what LED lighting technology standards

　　First, led light source : high brightness and high luminous efficiency must use low-light decline led chip package, it is necessary to choose the brand led lamp beads with chip makers such as U.S. Bridgelux / EPIstar Taiwan such formal channels chip package , the package of gold line / phosphor / insulating plastic material so needed to meet the requirements .

　　Second, the power supply: 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 power efficiency , power up the entire fixture crucial factor, but the current market led power quality is uneven, mixed set of ichthyosaur , a good drive power is not only to ensure the stability of the DC confessed , but also to fully guarantee the conversion efficiency, this parameter is reflected lighting the real energy and the power grid is not wasted .

　　Third, the appearance of the compact structure of the cooling system , an excellent addition to the appearance of high-end lighting and generous , high-quality light and power, but also more importantly the reasonableness of the shell structure , which involves cooling problems led lamps , led the conversion of light energy due at the same time , there are also a part of the electrical energy into heat energy , the need to heat leads into the atmosphere , so as to ensure the stability led lights , led lights high temperature will cause the light fades faster, have an impact on the life of led lights . It is worth mentioning that led chip technology continues to improve, the conversion efficiency is improved, the conversion of heat energy consumption will be less, radiator parts will use thinner , also due to some lower costs , help led promotion, but this is just a technical development, for now must focus on the cooling of the housing or study parameters.

　　Fourth , LED lamp lenses often also ignored by some of the designers , in fact, the refraction of light will produce light loss , the lens is a lens is also profoundly affect the final output flux , the current lens better light transmittance up to 93 or more due to the cost of the lens is more important , so some of the plant in order to save costs and some cheaper lens material is certainly using secondary materials , light transmittance of about 70 , with the naked eye can not see how to deceive consumers, but in fact instruments it is easy to test out the results of the lens material is relatively poor , with a long bad results will be yellow and so on.
