Oremark UV Bead Structure

Will many people want to know the internal structure of light diode lamp beads? The same is true for Xiaobian, so I specially asked professionals to compile such information for your reference. UV light diode refers. Ultraviolet light is usually used to identify whether the banknotes forgery, and some ultraviolet light diode lighting objects are very popular at night clubs and parties. They are used to make fluorescent substances emit more bright light. Its basic structure is a semiconductor material of electrostatic glowing, placed on a leading shelf, and then seal with epoxy resin around it to protect the internal core wire. Therefore. The core part of the emitting diode is a chip consisting of P -type semiconductor and N -type semiconductor. There is a transition layer between the P -type semiconductor and N -type semiconductor, called the PN knot. In the PN knot of certain semiconductor materials, the small load -in -load and most carrier are released when the carrier is released in the form of light, so that the electric energy is directly converted to the light energy to the light energy. Pn knot plus reverse voltage, a few carrier is difficult to inject, so it does not emit light. This diode made of injecting electrophoretic lighting principle is called luminous diode, which is commonly known as LED. When it is in a positive working state (that is, the two ends plus a positive voltage), the current flows from LED anode to cathode, semiconductor crystals emit light from ultraviolet to infrared color. The technical characteristics of ultraviolet light diode; 1) 5mm purple light uses glass packaging and nickel -plated alloy shells, which further improves the lighting efficiency of purple light, reduced the decay of purple light, extended the service life of the service life, and extended the service life. 2) Two pins use gold -plated technology. 3) High emotional strength. 4) Stable and reliable quality.
