In the LED lamps, the heat is directly related to the quality and life,the radiator’s main role is that heat generated by the LED chip is continuously exported and distributed to the environment, so that the chip temperature is maintained within the required range , thus ensuring LED lights properly work. The quality of the heat sink mainly depends on thermal resistance the radiator, the smaller the thermal resistance,the lower the junction temperature of the LED light under the same conditions , the longer the service life of the chip. Under the certain environmental conditions, the heat resistance depends on the sink area of the heat sink, the greater the area of the heat dissipation, the higher the coefficient of the radiation, the smaller the heat resistance, the better the heat dissipation. Thus, LED lamps radiator must have a certain cooling area, while the material making the radiator must have a certain degree of thermal conductivity and high thermal emissivity, the heat conduction is essentially impossible to go outside when LED work. temperature of the air inside the LED beads has reached the 101 degree, the highest temperature is the fifties degrees on the surface of the lamp, a difference of several tens of degrees. |
Some lighting designers almost entirely don’t understand the material properties, parrot; because their supervisor or boss also completely don’t know. What the Boss is concern about is the inexpensive and lowest cost. However, if the heat sink material is not applicable, which can not play a real cooling effect, the end result is that the brightness and life of LED beads is reduced, beyond doubt,and thus the overall service life of LED lighting products are also damaged
the material of the Lamp shell The transparent PVC ,acrylic is adopted for the Low-end products, the PC material is used for the slightly better. Low-grade goods: PVC, PE, transparent or frosted acrylic.
Mid-range products: PC. Luxury goods: special polymer plastic material. As for the quality of these materials, we all know. Now many companies do not have their own design, but there is not creativity at all. Most think that as long as the use of LED lamp fixtures, saying he is what the LED industry, especially some large companies is more so. Instead, I would think that many small exported companies pour a lot of thought on the quality and design of the LED, but having no government support, those big company combining some officials and sexy and inferior products cheat subsidies. This is Market field, many manufacturers seem to be experts no mater what lamps they do, and now those good chips, good technology are hold by the hands of all foreign manufacturers.
Chinese LED industry is generally lack of core technology, experienced excess capacity, product prices, small business failures and other problems and crisis. Today, in terms of policy support funds, may ushering in a good stage of development, but if the core technology and technological innovation do not be improved, it is likely recommit the same error, again facing the overcapacity crisis of LED industry. So many LED manufacturers are desperately looking for such LED lamps whose cost is low to manufacture, there is a reason.
However, LED lighting manufacturers deceive consumers in the way, the consequences are very serious, look, last month, the scale of a billion dollars, “Hung Kee Lighting boss on foot incident” caused many LED lighting manufacturers concerned, I believe that many LED lighting manufacturers will change from the perspective of technological innovation.
Fortunately,there are still a large number of excellent manufacturer engaging in manufacturing and researching the LED light,of which the lead lighting is just one,lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ,login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.
