Background

LEDs, light emitting diodes, are solid state semiconductor devices that convert electrical energy into visible light, and can convert electricity directly into light. The heart of the LED is a semiconductor wafer, one end of the wafer is attached to a support, the other end of the wafer is a cathode, and the other end of the wafer is connected with an anode of a power supply, so that the whole wafer is packaged by epoxy resin.

The semiconductor wafer is composed of two parts, one of which is a P-type semiconductor in which holes predominate and the other of which is an N-type semiconductor in which electrons predominate. When the two semiconductors are connected, a P-N junction is formed between them. When current is applied to the wafer through the wire, electrons are pushed to the P region where they recombine with holes and then emit energy in the form of photons, which is the principle of LED lamp illumination. The wavelength of the light, i.e., the color of the light, is determined by the material forming the P-N junction. LEDs can emit light directly in red, yellow, blue, green, cyan, orange, violet, white.

The LED lamp has excellent energy-saving property and is applied more and more widely, and the high-power LED lamp has a tendency of replacing the existing halogen street lamp as a lamp for lighting large public places such as street lamps and the like. On the other hand, the heat productivity of the high-power LED lamp is quite high when the high-power LED lamp is used, if the heat is not dissipated in time, the illumination of the LED street lamp can be influenced, the service life of the LED lamp is shortened, the LED lamp can be burnt seriously and even can be caused, and therefore, the research on the heat dissipation performance of the LED street lamp is the key of the LED street lamp technology.

An LED lamp is a lamp using a light emitting diode chip, i.e., an LED chip, as a light emitting element. Such a luminaire must be equipped with a heat sink for the LED chip. The existing LED lamp is radiated by the natural flow of air, and the radiating effect is poor.
