Environmental durability test of road vehicle lamps

Automobile lights must undergo a series of environmental tests before being put into use to ensure product quality. The environmental durability test of road vehicle lamps can measure the environmental durability of external lighting and light signaling devices of motor vehicles and trailers, including heat cycle resistance, thermal shock resistance, heat deformation resistance, salt spray resistance, dust resistance, random vibration resistance, waterproof performance, strength performance, resistance to lubricating oil, fuel and cleaning fluid resistance, and light source irradiation suitability.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various lighting devices and provides professional environmental durability testing services for external lighting and optical signaling devices of road vehicles.

Vehicle front lights include: low beam, high beam, front position lights, daytime running lights, front turn lights, front fog lights, corner lights, side turn lights, parking lights;
Vehicle rear lights include: brake lights, rear position lights, rear turn lights, reversing lights, rear fog lights, rear retroreflectors, high-mounted brake lights, license plate lights;
Common lights for large vehicles include: front profile lights, rear profile lights, side marker lights, reflective logos, and tail sign boards.

Thermal cycle test of headlamps and front fog lamps, general thermal cycle test, thermal shock test, thermal deformation test, salt spray test, dustproof test, random vibration test, waterproof test, light intensity test, lubricating oil resistance, fuel resistance and cleaning fluid resistance test, light source irradiation test applicability
