LED lamp pearl structure convenient to change

Technical Field

Background

An LED is a light emitting diode, a solid state semiconductor device that can convert electrical energy into visible light, and can directly convert electricity 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.

The LED lamp has the advantages that: energy is saved, and the energy consumption of the white light LED is only 1/10 of an incandescent lamp and 1/4 of an energy-saving lamp; long service life, the service life can reach more than 10 ten thousand hours; the energy-saving lamp can work in a high-speed state, and if the energy-saving lamp is frequently started or turned off, the filament can be blackened and quickly broken down, so that the energy-saving lamp is safer; solid state packaging, which is a type of cold light source, so it is well transported and installed, can be installed in any miniature and closed equipment, and is vibration-proof; LED technology is advancing day by day, its luminous efficiency is making a striking breakthrough, the price is also decreasing, an age of white light LED entering home is coming rapidly.

The existing LED lamp is directly welded on the substrate, the substrate needs to be heated when being disassembled, and the LED lamp can be disassembled, so that the process is very troublesome, the time is wasted, and the efficiency is low.
