Transportation lighting has become an important application market for LED as an illumination source. At the 2010 Shanghai International New Light Source & New Energy Lighting Forum's 'New Light and Transportation Lighting Transformation' special summit, guests from the semiconductor lighting field and LED related application companies The application of semiconductor lighting in tunnel lighting, rail transit lighting, automotive lighting, etc. has been heatedly discussed, and the good development prospects of various markets have become the focus.
At present, LED has been applied to the interior and exterior of automobiles, especially in automotive interior lighting. The application of color LEDs is very mature, such as for instrument panels, backlight switches, car reading lights or head-up display systems, or in the car. The 'Color-on-Demand' feature allows automakers to differentiate themselves from other competitors by using their own unique color, or to use color to distinguish between different series of products. Zhong Jiecong, Marketing Director, Asia Pacific, Osram Opto Semiconductors Asia Ltd. said.
Automotive external applications are also constantly evolving. Zhu Minghua, director of the electronic technology department of Shanghai Xiaohao Auto Lamp Co., Ltd., has introduced LEDs for brake lights, taillights, turn signals, reversing lights, high-position brake lights, etc. The taillights also have a large application of high brake lights. As a vehicle headlamp illumination, due to the need for high-power LEDs, it is subject to technology and LED cost-effectiveness, especially in the fields of optics, electronic control, and thermal management. It takes three to five years for the industry to become popular. It is also only available on some luxury high-end models.
Led Bulbs are more energy saving than traditional bulbs. They feature with stable performance, long life, high lumen, soft light, top quality, no flashing, no UV or IR radiation, environment-friendly. And their design is more flexible and diverse. LED bulbs using the existing interface, that is, screw mouth (E26 \ E27 \ E14, etc.), jack (B22, etc.), and even to meet people's habits to imitate the incandescent bulb shape. Based on the principle of LED unidirectional light, the designer has made changes in the structure of the lamp so that the light distribution curve of the LED bulb is basically the same as that of the incandescent lamp.
