Abstract

The invention relates to a detecting device for LED light source automotive lamps, in particular to a light distribution detecting device for an automotive LED headlamp. The detecting device comprises a darkroom and a headlamp light distribution system arranged in the darkroom. A UV-VIS spectrometer which can receive output signals of the headlamp light distribution system is further arranged in the darkroom. The UV-VIS spectrometer can convert light signals to electric signals and transmit the converted electric signals into a computer. The computer can further control the headlamp light distribution system. By the adoption of the structure, the headlamp light distribution system is combined with the UV-VIS spectrometer, measurement of red light ratio and UV light ratio is completed through computer processing calculations, and therefore the LED headlamp can be detected through an existing automotive headlamp light distribution testing system; accordingly, the application range of the system is further expanded, the usage effect is good, and the requirement of technological development is met; meanwhile, the structure is simple, measurement is convenient, and therefore the detecting device has excellent application and popularization prospects.

Description

technical field [0001] The invention relates to a detection device for an LED light source automobile lamp, in particular to a light distribution detection device for an automobile LED headlamp. Background technique [0002] With the widespread use of LEDs in the lighting field, it is an inevitable choice for LED car headlights to replace traditional car headlights. The light distribution standard of traditional headlights is GB4599-2007 "Filament Bulb Headlights for Automobiles". At present, the light distribution testing equipment of headlights at home and abroad are designed according to this standard. The light distribution standard of LED headlights for automobiles is GB25991-2010 "LED headlights for automobiles"; compared with the light distribution standard GB 4599-2007 of traditional headlights, the light distribution standard of LED headlights for automobiles GB25991 -2010 requires the measurement of the ratio of red light to total luminous flux at the HV point or ...
