Product Description
Car headlights needs to undergo strict quality inspection in the production process to ensure that it meets the requirements of relevant standards and regulations. Generally speaking, car headlights's quality inspection includes the following aspects:
1. Optical performance test: including light transmittance test, light beam distribution test and light intensity test. The light transmittance test is used to detect the light transmittance of lampshades, the light beam distribution test is used to detect the illumination range and uniformity of lamps, and the light intensity test is used to detect whether the illumination intensity of lamps meets the standard requirements.
2. Heat resistance test: car headlights will be affected by high temperature during its work, so it is necessary to carry out heat resistance test. The high temperature resistance and stability of the lamp were tested by heating it in high temperature environment for a long time.
3. Waterproof performance test: car headlights needs to have good waterproof performance to ensure that it can still work normally under bad weather conditions. The waterproof performance test includes immersion test and water spray test to test the tightness and waterproof performance of lamps.
4. Impact resistance test: car headlights needs to have certain impact resistance to cope with the collision and vibration that may be encountered during the running of vehicles. The impact resistance test includes static impact test and dynamic impact test to test the structural strength and seismic performance of lamps.
5. Other tests: According to specific requirements, other tests such as weather resistance test, chemical stability test and electrical performance test can be carried out to ensure the overall quality of car headlights.
To sum up, car headlights's quality inspection includes optical performance test, heat resistance test, waterproof performance test, impact resistance test and other test items. Through strict inspection and evaluation, it is ensured that car headlights has good performance and quality, and meets users' needs and safety requirements.
