LED how is the band embedded in the steps?
The LED lamp band is embedded on the steps: fixed on the steps with double-sided adhesive or glass adhesive or fixed clip.
Initially, LED was used as an indicator light source for instruments and meters. Later, various light colored LED were widely used in traffic light and large area display screen, which produced very good economic and social benefits. Take the 12 inch red traffic light, for example, in the United States where a 140 watt watt hour light bulb with long life and low light efficiency was used as a light source, producing 2000 lumens of white light. After the red filter, the light loss is 90%, leaving only 200 lumens of red light. In the new design of the lamp, Lumileds company uses 18 red LED light sources, including circuit loss, including a total power consumption of 14 watts, which can produce the same light effect. Automobile signal light is also an important field of LED light source applications.
LED (Light, Emitting, Diode) light emitting diode is a solid-state semiconductor device that converts electrical energy into visible light. It can directly convert electricity into light. The heart of LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other is connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin. Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of the LED light shining. The wavelength of light, that is, the color of light, is determined by the material that forms the P-N junction.
LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good.
