A rich, good monochromaticity, colorful. Color saturation of 130% full color, make the light more clear and soft. Second, long life, good vibration resistance. LED is a semiconductor device, unlike incandescent bulbs, no reasons of moving parts, such as glass, tungsten failure is extremely low, can free maintenance. Three, short response time, only 60 nanoseconds, especially suitable for used in automobile lamps light source, to strive for the driver's precious decrease the time of the accident. Four, high efficiency, low energy consumption. LED light source does not need to screen can directly produce automobile lamps and lanterns need color such as red, amber, lossless, energy utilization rate is as high as 80% above. Fifth, small volume, light weight. Using its characteristic can be design and thin, compact and light, and the various styles of lamps and lanterns, to provide automobile modeling design space. Six, green lighting light source. LED spectral good monochromaticity, there is no excess infrared, ultraviolet spectrum, such as mercury does not contain harmful substances, little heat, radiation, and so on. Seven, small single LED luminous flux. The luminous flux research level of the individual leds can reach 120 lm/W, product level 60 lm/W or less, are often very to increase the size and high power LED radiator, so LED light source with LED array design method. Eight, flat light, strong directivity. It differs from the point light source incandescent lamp, visual Angle 180 ° or less, when the design must pay attention to and the use of LED light source has a different visual Angle and is not greater than 180 ° the characteristics. Nine, LED luminous efficiency varies with temperature drop, general chip temperature over 120 ℃. In the design and manufacture of lamps and lanterns assembly process design must consider thermal design. Ten, LED belong to multiple compound semiconductor components. Multivariate compound semiconductor element is characterized by its electrical, optical, thermal and mechanical parameters of discreteness. , when the design must be fully considering the characteristics, and required components manufacturing company in accordance with the requirements of automotive LED light source for strict, sorted, graded and components.
