上海汽车研究所与上海南北电气有限公司共同开发采用全集光超高光效固体光源(简称新光源),研制出汽车用的组合后灯,高位制动灯。这是汽车灯具的一项新技术。 它与装有普通白炽灯泡的汽车组合后灯,高位制动灯相比较,其优点如下: 1.工作寿命长。汽车用的白炽灯泡一般工作寿命为200～500h,而新光源的工作寿命可达10万h。 2.功率消耗小。汽车用的白炽灯泡的功率为27W(转向灯、制动灯、位置灯、雾灯、高位制动灯。),新光源的功率为9.2W,是前者的1/3。 3.瞬间发光,响应速度快。汽车白炽灯泡通电后的发 Shanghai Automotive Research Institute and Shanghai North and South Electric Co., Ltd. jointly developed the use of the whole collection of ultra-high light efficiency solid light source (referred to as the new light source), developed a combination of automotive lights, high brake lights. This is a new technology for automotive lighting. It is compared with the combination of rear lights, high brake lights with ordinary incandescent light bulbs, the advantages are as follows: 1. Long working life. The incandescent light bulbs used in automobiles have a typical working life of 200 to 500 hours, while the working life of new light sources can reach 100,000 hours. 2. Power consumption is small. Incandescent bulbs for cars have a power of 27W (turning lights, brake lights, position lights, fog lights, high brake lights.) The new light source has a power of 9.2W, which is 1/3 of the former. 3. Instant light, fast response. After the car incandescent light bulb hair
