LED lighting applications, as an alternative to achieve a light source close to the original brightness requirements, usually adopt a “quantity” winning design approach that is designed in a unit area of a large number of LED light emitting elements or a single element is taken to enhance the luminous efficiency of the design, but this, that cause or point planar element temperature urgent treatment, while cooling means are available to take active or passive design, particularly in the active cooling design is more complex, and how to achieve optimal thermal design avoid bad light LED elements affect the life, is the key to the development of high-brightness LED lighting.
LED (LightEmittingDiode) solid-state lighting is great potential in recent years, is considered the future of the industry, as consumers and industry caught looking, you can use LED solid-state lighting to solve a lot of energy wasted in inefficient illumination problem, because LED with volume small, high luminous efficiency, energy saving and other advantages, so most people have on the future development of LED solid-state lighting high hopes. For the LED solid-state lighting technology with traditional light sources emitting different, more environmentally friendly, energy-saving aspects of a number of advantages, the first observation of common everyday lighting, nothing more than incandescent and fluorescent, incandescent basically in luminous efficiency performance that tends to be a disadvantage, even with low-cost and other advantages habits have been established, but the rise of the concept of environmental protection under the social atmosphere, has become an environmentally friendly, non-efficient lighting products. In fluorescent lamps, although mining high-frequency gas discharge optical technology to achieve power efficiency, but in fact fluorescent control process can not be avoided environmentally harmful mercury, the demands on environmental protection is not the best choice of light sources.
LED solid state light source back to the development of early multi-LED light source is used to indicate that the signal, an indicator light medium / low brightness and low power drive source applications, so the heat is not considered, one is indicated by a light source currently used only to identify the status of the device, switch status prompt, not for lighting purposes, because the drive power is not high and no significant natural cooling problems to be solved. But the question is, the intended use of high brightness LED, the most environmentally friendly alternative to the light source for development, so the design approach will cause a lot of impact.
When the LED solid-state light source toward the direction of thinking everyday lighting applications, there will be bright enough problems, we must try to improve power utilization increased luminous efficiency of the LED elements, or the use of a greater number of high-brightness LED conduct modular design, allowing a light source for lighting applications with a “high brightness” requirements.
