Li98 Thermally Conductive Adhesive Tape for LED Lighting Applications Slide 2

During the last ten years, developments in LED semiconductors have led to an important change in LED applications from that of luminous indicator to that of illuminator. With LEDs now advancing into several lighting fields, LEDs have become one of the standard methods of producing light, joining more traditional sources such as incandescent, fluorescent, and high-intensity discharge (HID). LEDs offer a number of key benefits. For example, the operational life of current white LED lamps is 100,000 hours. The long operational life of a led lamp is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours. If the lighting device needs to be embedded into a very inaccessible place, using LEDs would virtually eliminate the need for routine bulb replacement. There is no comparison between the cost of LED lights vs. traditional incandescent options. With incandescent bulbs, the true cost of the bulb is the cost of replacement bulbs and the labor expense and time needed to replace them. These are significant factors, especially where there are a large number of installed bulbs. For office buildings and skyscrapers, maintenance costs to replace bulbs can be enormous. These issues can all be virtually eliminated with the LED option. Unique to LED lighting is the fact that the source of light is a semiconductor rather than a filament, gas discharge, or arc. This is changing the technology associated with the development of lighting, how the lighting will be used, and how the thermal challenges must be resolved. This product training module addresses these issues.
