LED is the abbreviation of English light emitting diode. Its basic structure is an electroluminescent semiconductor material placed on a leaded shelf and then sealed with epoxy resin to protect the inner core. .
In addition, LED light sources have many advantages as follows:
Voltage: LED uses low-voltage power supply, the power supply voltage is between 6~24V, depending on the product, so it is a safer power source than high-voltage power supply, especially suitable for public places.
Performance: Energy consumption is reduced by 80% compared to incandescent lamps with the same efficacy.
Applicability: Very small, each unit LED chip is 3~5mm square, so it can be made into various shapes and suitable for variable environment.
Stability: 100,000 hours, the light decay is the initial 50%.
Response time: The response time of its incandescent lamp is millisecond, and the response time of LED light is nanosecond.
Environmental pollution: no harmful metal mercury.
Color: changing the current can change color. The light-emitting diode can conveniently adjust the energy band structure and band gap of the material by chemical modification method to realize multi-color luminescence of red, yellow, green and blue. For example, a red LED with a small current turns orange, yellow, and finally green as the current increases.
LED is called the fourth-generation car light source. In addition to high-level one-time investment, LED lights have the advantages that high quality and high grade incandescent lamps can't match, and there is no delay, energy saving, longevity, low heat, shock resistance, high color purity, etc. It has become an inevitable replacement for tungsten lamps and halogen lamps.
In addition, auto LED lighting products at home and abroad is very fire of automotive accessories, which is a new type of car decoration products, which combines safety, practicality, decorative as a whole. Because the car LED chassis lamp has good waterproof performance and impact resistance, it usually has no maintenance and no scrubbing. The power is only equivalent to the power of a car headlight. It does not impose excessive burden on the car battery and the engine when used. The product is installed on the bottom of the car (or inside the car). On night, foggy, rainy and poor visibility, it can provide your car or its 36 vehicles with the location identification of your car or parking. Reduce accidents. Open the LED lights at night, the bottom of the car (or the interior of the car) presents a variety of red, blue, green and other discoloration, very beautiful, the product is very popular with young car owners.
