The LED is a green light source. LED lamp DC drive, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong directionality; good dimming performance, no visual error when color temperature changes; cold light source Low heat and safe touch; these are not possible with incandescent and fluorescent lamps. It not only provides comfortable lighting space, but also satisfies people's physiological health needs. It is a healthy light source that protects vision and is environmentally friendly. Since the current single LED has low power and low brightness, it is not suitable for use alone, and assembling LEDs together to design a practical LED lighting fixture has broad application prospects. The luminaire designer can determine the shape of the optical system of the luminaire, the number of LEDs and the power according to the requirements of the illumination object and the luminous flux. It is also possible to design several LED illuminating tubes into a secondary source of point light source, ring light source or surface light source. The luminaire is designed according to the combined secondary light source.
The term LED lamp supplier is popular in China in recent years, and people familiar with the lighting industry are no strangers. Semiconductor light-emitting diodes, referred to as LEDs, have been developed since the 1960s and are gradually becoming market-oriented. For those unfamiliar with the lighting industry, the following describes semiconductor light-emitting diodes:
First, the energy consumption is low, and the light decay is small. The brightness of a 1W LED is equivalent to a 35W halogen spotlight. In the history of the development of lamps, local lighting has always been the absolute leading position of halogen lamps and metal halide lamps. The birth of LEDs will replace them in the future.
Second, the long service life, no need to replace the light source, no maintenance, this is actually the most worrying problem for consumers. Consumers are not professionals, there is no professional inspection equipment when selecting products, no professional maintenance knowledge, and LEDs solve their worries.
At present, the sales of LED automotive lighting market maintains a growth rate of about 10 per year, but the proportion of domestic LED automotive lamps is not high. The models with relatively large LED usage are concentrated in the mid-to-high-end auto companies, and these auto companies generally have restrictions on the LED brand, and domestic LED companies are more difficult to enter their supply chain. In addition, compared with international famous brands, domestic LEDs may have more problems in terms of life and uniformity of sorting. At the same time, the market regulation of auto lamps itself is strict, the threshold is relatively high, and automobiles are sold as luxury consumer goods. For one-to-one customers, any quality problems will cause complaints. Domestic LEDs have no chance to go through this market for a long time, and it is difficult to meet the LED standards for vehicles. Automobile lamps are very professional fields. It is necessary to do LED car lamps. Whether it is car lighting companies or LED enterprises, it is very difficult to go it alone. It is necessary for car lighting companies to fully communicate with LED companies, especially in front of LED cars. Development of the light.
