Light-emitting diodes (leds) substrate circuit design for the influence of the luminous flux maintain rate

Light-emitting diodes (leds) substrate circuit design for the influence of the luminous flux maintain rate

Pick to: in view of the application of leds in full swing, the article analyses the light-emitting diode heat conduction path, the contrast test under different substrate circuit leds luminous flux change, puts forward the leds cooling circuit design principles. Keywords: light-emitting diode circuit heat flux Is: One, the introduction In 1962, americans holos Virginia ke produced the world's first light emitting diode (LED). With the improving of the photosynthetic efficiency, costs fell sharply and application of the technology mature, LED by more and more widely used, indication, landscaping, lighting, display, communications, etc. LED advantage of long life. LED life of up to 100000 hours of theory, but the actual service life is only tens of thousands of hours, or even thousands of hours. In addition to the LED itself quality, are the main factors affecting the service life of the LED the actual drive current, the cooling capacity and environmental conditions [1], and heat capacity mainly depends on the thermal resistance, heat dissipation area effectively. LED substrates including copper clad layer (circuit), dielectric layer and the base material layer (such as aluminum, epoxy resin, phenolic resin varieties). Copper substrate circuit design is mainly aimed at plane shape design, to meet the needs of the electric. But the base board circuit is a thermal mediation, common LED lamps and lanterns of heat conduction path [2] the diagram below.
