High Brightness LED structure features and applications

Although the LED is a current device - high-brightness LED is no exception, but the car taillights, brake, turn signal lighting and other applications can still benefit from the voltage driver structure.
When efficient LED available for use, retail and residential LED interior lighting may soon appear. LED manufacturers are only just beginning to address the problem of high color temperature.
Due to the high brightness LED manufacturing process, device design, assembly progress in technical aspects, lcd module light-emitting device performance has been improved, and its cost has been reduced, performance improvement and cost reduction of the speed memorable. PN junction design, and the lens re-radiation structures phosphor helps improve efficiency, it also helps to improve the availability of light output (with the text "lab LED"). On high-output white LED, the wide spectrum of performance improvement for general lighting makes low-maintenance energy-efficient light sources hopeful.
Although achieve comparable with standard fluorescent LED efficiency will take some time, but as semiconductor lighting industry association (Semiconductor Lighting Industry Association) Chairman Yung S Liu said: "LED light is more environmentally friendly products, because it is not the same as fluorescent lamps, do not use mercury. "
Solid-state lighting components and work in the environmental advantages of the current efficiency is not the major market drivers, but it does make this technology and its suppliers have a good image.
At the same time, working in a variety of fields for OEM designers and marketing staff have been expanding the scope of the practical application of solid-state lighting, and has been closely watching the market acceptance. However, the end user in the solid-state lighting device life experience different cost-benefit, which is very different from traditional lighting equipment. The fact that market values ​​change complicated. And compared to incandescent light bulbs and fluorescent light bulbs, high brightness LED usage and maintenance costs are much lower, which can offset the higher initial cost of lcd graphic display modules  Although the above discussion may be very attractive, but make it in the "price first, others second," mindset dominated the consumer market caused great difficulty selling.
Light fixture manufacturers traditionally not considered in their design lamp thermal management, just to make sure to provide adequate convection tungsten high operating temperature will not bring fire danger surrounding materials or fixtures operator burn hazard. The fact that a high output solid-state lighting device mass complications. However, if the final design is to make the LED light output and lifetime best, then the high-brightness LED fixture requires a certain degree of thermal design.
Thus, although not soon see high-brightness LED from the traditional incandescent or fluorescent hardware stores and home centers crowding out on the shelves, but these devices are into automobiles, traffic control, external signs and other market segments, because in all of these areas, high efficiency and long lamp life will increase the apparent value.
