Led corn lamp is a kind of led lamp, because the maximum led angle of 120 degrees, taking into account the luminous uniform, specially designed into 360 degrees light, its shape as corn cob, especially called led corn lamp.
LED is known as the fourth generation of lighting or green light source, with energy saving, environmental protection, long life, small size and other characteristics, can be widely used in a variety of instructions, display, decoration, backlight, general lighting and urban night and other fields. Some of the world's economically developed countries around the development of LED launched a fierce technical competition. The United States from 2000 to invest 500 million US dollars to implement the "National Semiconductor Lighting Program", the EU also announced in July 2000 launched a similar "Rainbow Plan." China's Ministry of Science and Technology in the "863" plan with the support of the first time in June 2003 proposed the development of semiconductor lighting program. Over the years, LED lighting with its energy saving, environmental protection advantages, has been the national and all levels of government attention, around the introduction of relevant policies and initiatives to accelerate the development of LED lighting; mass consumers are also environmentally friendly new lighting products have been eager Long. However, due to the high cost of technology and promotion, making thousands of consumers eager to wait for LED lighting products has been elusive, the delay has not opened its mysterious aristocratic veil!
With some domestic manufacturers of technology and production costs, LED lighting applause is not the situation will change. Cheap LED lighting products, will give China's lighting industry to bring a revolutionary impact for the vast number of consumers bring the gospel of light!
High energy: energy-saving energy pollution is environmentally friendly. DC drive, ultra-low power (single tube 0.03-0.06 watts) electro-optical power conversion close to 100%, the same lighting than the traditional light source more than 80% energy saving.
Long life: LED light source it is called longevity lamp, meaning never turn off the lights. Solid cold light source, epoxy resin package, the lamp body is not loose part, there is no filament light burning, heat deposition, light failure and other shortcomings, the service life of up to 60,000 to 100,000 hours, 10 times longer than the traditional light source life the above.
Change: LED light source with red, green and blue three primary colors principle, in the computer technology under the control of the three colors with 256 gray and arbitrary mixing, can produce 256 × 256 × 256 = 16777216 kinds of colors, the formation of different light color The combination of changing, to achieve a variety of dynamic changes in the effect and a variety of images, you can also choose a variety of colors instead of ordinary tungsten bulb, higher brightness.
Environmental protection: environmental benefits better, no ultraviolet and infrared spectrum, no heat, no radiation, glare small, and waste can be recycled, no pollution does not contain mercury elements, cold light source, you can safely touch, are typical green Lighting source.
High-tech tip: compared with the traditional light monotonous luminous effect, LED light source is low-voltage microelectronics products, the successful integration of computer technology, network communications technology, image processing technology, embedded control technology, it is also digital information products, Semiconductor optoelectronic devices "high-tech tip" technology, with online programming, unlimited upgrades, flexible features.
LED to efficient energy-saving environmental protection is well known, but the LED itself is still some problems, LED lights are no exception.
Industry for heat dissipation can be heat conduction (HeatConductivity) and heat (Heatdissipation) both sides have been discussed. For the industry in the LED cooling is too much emphasis on the front side of the practice of adding heat conduction layer, crown of the company's vice president of research and development, Dr. Ye Shengwei, made a very different from the industry's general approach to the fundamental solution. Dr. Yip pointed out that if the following thermal resistance formula Rtotal = Rl-s + Rs + Rs-a is introduced, the total LED thermal resistance is the thermal resistance (Rl-s) between the LED and the Substrate substrate, plus the substrate thermal resistance Rs) plus the sum of the substrate-to-air-side thermal resistance (Rs-a).
The industry's preferred MCPCB heat-dissipating aluminum substrate consists of a bottom aluminum block with an upper layer of copper foil and Adhesive. How to better solve the heat problem, this is a worthy of study.
In order to better solve the heat problem, developed a full aluminum lamp body of corn lamp. Using aluminum for the lamp body, plus aluminum plate. Can be a good solution to heat problems, thereby increasing the lamp life
