What is PCB in LED light?
LED is an Electronic Resistor and Capacitor with bare PCB for light emitting diode, which is semiconductor diodes. The LED is soldered to the printed circuit board and features a originality electronics IC that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the Electronic connectors and chips.
LED is the abbreviation of English light emitting diode (light emitting diode), its basic structure is a piece of electroluminescent semiconductor material, placed on a leaded shelf, and then sealed with epoxy resin around to protect the internal core wire Function, so the seismic performance of the LED is good. LED characteristics and advantages: The inherent characteristics of LED determine that it is the most ideal light source to replace the traditional light source, and it has a wide range of uses. Small size LED is basically a small chip encapsulated in epoxy resin, so it is very small and very light. Low power consumption LED power consumption is very low, generally speaking, the working voltage of LED is 2-3.6V. The working current is 0.02-0.03A. This means: it consumes no more than 0.1W of electricity. Long service life Under proper current and voltage, the service life of LED can reach 100,000 hours. High-brightness, low-calorie environmentally friendly LED is made of non-toxic materials, unlike fluorescent lamps that can cause pollution with mercury, and LEDs can also be recycled. use. Rugged and durable LEDs are completely encapsulated in epoxy resin, which is stronger than light bulbs and fluorescent tubes. There is no loose part in the lamp body, these features make the LED can be said to be difficult to damage
Led light must use the Aluminum base board (metal-based heat sink includes aluminum substrate, copper substrate, iron substrate) is a low-alloyed Al-Mg-Si series high-plasticity alloy plate, which has good thermal conductivity, electrical insulation properties and mechanical processing properties.
PCB: (PrintedCircuitBoard), the Chinese name is printed circuit board, also known as printed circuit board, printed circuit board. It is an important electronic components, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.
