As an important part of automobile lamps, automobile reflector needs to have the following characteristics:

1. High reflectivity: The internal reflective surface of the automobile reflector needs to have high reflectivity, which can effectively reflect the light emitted by the bulb and improve the lighting effect and brightness of the lamp.

2. Good focusing performance: The design and shape of the reflector need to be able to focus the light, focus the light on a specific area, and improve the illumination range and uniformity of the lamp.

3. Heat resistance: the automobile reflector needs to have good heat resistance and can withstand the high temperature light emitted by the bulb without deformation or damage.

4. Weather resistance: The reflector should have good weather resistance, be able to resist the influence of external environmental factors such as ultraviolet rays, high temperature and moisture, and maintain a long-term and stable reflection effect.

5. Light transmittance: The material of the reflector needs to have good light transmittance, so that the light emitted by the bulb can pass through the reflector and radiate effectively to improve the lighting effect.

6. Waterproof and dustproof: Some automobile reflectors need to be waterproof and dustproof, which can effectively prevent water vapor and dust from entering the lamps and protect the bulbs and circuits from being damaged.

To sum up, the automobile reflector needs to have the characteristics of high reflectivity, good focusing performance, heat resistance, weather resistance, light transmittance, waterproof and dustproof, so as to ensure that the lamp has good lighting effect, stability and service life. Consumers should comprehensively consider the above characteristics according to the vehicle model and demand when choosing the automobile reflector, and choose a suitable reflector to improve driving safety and comfort.
