Corner lamp.
A luminaire that provides auxiliary lighting near the road corner ahead of a vehicle or to the side or back of a vehicle. When the lighting conditions of the road environment are not sufficient, the corner light plays a certain role in auxiliary lighting and provides protection for driving safety. This kind of luminaire plays a certain role in auxiliary lighting, especially in areas where the lighting conditions of the road environment are insufficient.
The quality and performance of automobile lamps are of great significance to the safe running of motor vehicles.
What are the causes of car taillight failure?
Automobile taillight failure causes:
Bulb burn out: The life of the bulb expires or the bulb is damaged, causing the normal light.
Circuit failure: may be due to circuit connection problems, fuse blowout or circuit circuit short circuit causes the taillight to not work normally.
Switch failure: If the taillight switch is faulty, the switch status of the taillight cannot be controlled.
Vehicle battery problems: Low battery power or poor battery contact may cause the taillight to not work properly.
Vehicle impact or damage: Vehicle impact or damage may cause the taillight shade to break or wiring damage and not work properly.
DPA taillight core to solve problems: fading, cracking.
1, lampshade: DPA taillight lampshade using acrylic (PMMA) material, excellent optical performance, light transmittability up to 90%-92%, refractive index 1.49, good weather resistance, high surface hardness, ensure 5 years do not fade. Other brands use AS material, easy to oxidize, easy to fade, easy to crack;
2, light shell: DPA taillight shell using native ABS material, high plasticity, stable installation size;
3, reflector: DPA taillight reflector using PC/PET material + high brightness aluminum plating, higher brightness;
4, circuit board: DPA taillight circuit board using the original technology, LED lighting speed (< 1MS), high safety performance, long service life. Is it normal to have fog in the rear light water
It is normal to have fog in the water in the rear lamp.
The fog in the rear lamp water usually occurs when the internal temperature of the lamp is higher than the outside temperature and the outside humidity is larger. This is because after the lights are turned on for a period of time, due to the hot air discharged from the lamp through the vent tube, some external moisture may be brought into the lamp, resulting in a small amount of condensation or water fog on the inner wall of the lamp shade. This is especially true in winter when the temperature difference is large and when there is more rain. In addition, the ventilation rubber tube at the rear cover of the headlight is designed to remove the heat generated after the taillight is turned on, and may also allow moisture in the air to enter the headlight and adhere to the lampshade, forming water droplets.
Under normal circumstances, if there is only a small amount of condensate, this is a normal phenomenon. However, if a large area of fog condenses on the inner wall of the lens, condenses into water droplets, accumulates in the interior of the headlights, and when used for a long time or many times, the fog will adhere to the surface of the lens in a large area with the increase of the taillight temperature, which can be considered as water. Under normal use, the taillight will fog due to poor sealing. If there is fog, in the absence of lighting parked in a dry environment with less than 50% humidity for more than one day, the fog in the lamp will disperse.
In general, although the fog in the rear lamp water is not the ideal state of design, it can be regarded as a normal phenomenon under certain conditions. If the fog is serious enough to affect the use or persist, it may be necessary to check the sealing performance of the lights or consider maintenance measures.
