Know more about LED Technology

In recent years, with the continuous development of LED technology, as well as the continuous emphasis on energy conservation in society, LED has been used in all aspects of lighting, display, and other aspects of the need for light sources and the share in lighting and display is also increasing. From the perspective of automotive lighting, LEDs will surely replace traditional incandescent lamps and halogen hook lamps and become representatives of a new generation of light sources.

LED is the English light-emitting diode (light-emitting diode) abbreviation;  its basic structure is a piece of electroluminescent semiconductor material placed on a leaded shelf and then surrounded by epoxy resin seals,  which play a role in protecting the internal core.

The core part of the LED that forms a light-emitting diode is a wafer composed of P-type and N-type semiconductors. A transition layer between P-type semiconductors and N-type semiconductors is called PN junctions.  In the PN junction of some semiconductor materials, when the injected few carriers are combined with most carriers, the excess energy is released in light, directly converting the electrical energy into light energy. When the PN junction applies a reverse voltage, a small number of carriers are difficult to inject, so they do not emit light. If a solid semiconductor chip is used as a light-emitting material,  a forward voltage is added at both ends; that is,  when it is in a forward working state,  the current will flow from the LED anode to the cathode, and the semiconductor crystal will emit light of different colors. This spectrum is almost entirely concentrated in the visible light frequency range, and the diodes made in this way are called light-emitting diodes, also known as LEDs.

LED light source has the following advantages:

• Small size: LED is a tiny chip (the shape of each LED unit piece is a square with a side length of 3 to 5mm) encapsulated in epoxy resin, its small size, very light. It can be combined at will, and it is easy to develop into light, explosive, short, and other lighting products of various shapes, and it is also easy to install and maintain.    

• The response time of the fast response LED lamp is a nanosecond, and the response time of the incandescent lamp is a millisecond. The fast response speed makes it easy to control brightness and color, enabling dynamic color changes and digital control.   

• Voltage: LED uses a low-voltage power supply, the supply voltage is between 6-24V, depending on the product, so it is a safer power supply than a high-voltage power supply, especially suitable for public places.   

• Low power consumption, the general LED working voltage is 2-3.6V, the working current is 0.02-0.03A, and the power consumption is generally not more than 0.1W, so the power consumption is deficient.    Efficiency: The energy consumption is 80% less than incandescent lamps with the same light effect.   

• Stability: 100,000 hours, light decay is 50% of the initial. Response time: The response time of its incandescent lamp is at the millisecond level, and the response time of the LED lamp is nanosecond. Environmental pollution: no harmful metals.   

• Color: change the current can be changed
