Dongguan LED corn light advantages and disadvantages High energy saving, energy saving energy is the environmental protection from pollution. Dc drive, ultra-low power consumption (0.03-0.06 watts single pipe) electric power conversion is close to 100%, the same lighting effect than the traditional light source, energy saving more than 80%. Long life: LED light source has called it longevity light, meaning never extinguished the lights. Solid cold light source, the epoxy resin encapsulation, no loose parts in the body, there is no filament light easy to burn and thermal deposition, droop, such as faults, service life can reach 60000 to 60000 hours, long service life 10 times more than traditional light. Many changes: LED light source in red, green, blue three colors principle, in under the control of computer technology make the three colors gray level 256 and arbitrary mixed, can produce 256 * 256 * 256 = 16777216 kinds of color, form different combinations of light color changing, realize the dynamic change of rich and colorful effects and all kinds of image, also can choose a variety of color instead of the ordinary tungsten filament bulbs, higher brightness. The environmental protection, environmental protection benefit is better, no ultraviolet and infrared spectrum, no heat, no radiation, glare small, and waste recycling, no pollution contains no mercury elements, cold light source, can safely touch, belongs to typical green lighting source. High tip: compared with the traditional monotonous lighting effects, the LED light source is low pressure microelectronics products, successfully combines computer technology, network communication technology, image processing technology, embedded control technology, etc., so also is the digital information technology products, is a semiconductor photoelectric device "high point" technology, the online programming, unlimited upgrade, the characteristics of flexible. Disadvantages: led lamps and lanterns despite many advantages, but it is still in a very passive situation, exorbitant prices restrict its universality, cause it is difficult to into the ordinary people in the home, the second heat lamps and lanterns is also present a major problem, so to make the led lamps and lanterns is popularized to reduce cost and solve the fever of lamps and lanterns is a key problem. Dongguan LED corn light with high efficiency and energy saving environmental protection as well known, but the LED itself still has some problems, the LED corn lamp is no exception. The industry for heat dissipation from thermal conductivity (HeatConductivity) and heat (Heatdissipation) both sides have been discussed. For the industry on the LED heat sink too much emphasis on the practice of additional heat conduction layer on the front end, Dr Ye Shengwei product chemical company research and development vice President, different from the general practice of fundamental solution. Dr Leaf, points out that if the import of the following thermal resistance formula Rtotal = Rl - s + Rs + Rs - a, the LED total thermal resistance of LED to the thermal resistance between the Substrate Substrate (Rl - s), plus Substrate thermal resistance (Rs), and the base plate to the air side heat resistance (Rs - a) the sum of the three. The industry penchant for MCPCB radiator aluminum substrate is composed of aluminum blocks and upper copper foil at the bottom of the set, filling heat conduction glue (Adhesive) in the middle. How to better solve the problem of heat dissipation, it is a question worth studying. Dongguan LED corn light in order to better solve the problem of heat dissipation, developed a whole aluminum lamp body of corn lamp. Using an aluminum lamp body, plus the aluminum substrate. Can well solve the problem of heat dissipation, thus increase the life of lamps and lanterns |
