Description

An intelligent opening device for automobile LED lights

technical field

The utility model relates to the field of intelligent opening solutions for automobile lamps, in particular to an intelligent opening device for automobile LED lamps.

Background technique

At present, although xenon headlights are still the most mainstream car headlight configuration, since 2013, LED headlights have begun to enter more and more family cars. The application of LED lights in automotive systems mainly has the following advantages: First, the high color saturation makes the output light clearer and softer, which is in line with the characteristics of automotive headlights; second, it has long service life, durability, and shock resistance. Strong, can exceed 10,000 hours, while the life of traditional halogen lamps is generally about 300 hours; third, high efficiency, less additional loss, compared with the complex heat dissipation system of traditional lamps, it can be seen that the heat loss of LED lamps is much smaller , the conversion efficiency can reach more than 85%, which is especially suitable for the design concept of future cars that focus on energy saving; fourth, the response speed is fast, unlike traditional incandescent lights, HID lights require a longer driving delay to reflect vehicle conditions and road conditions in real time. Leave the driver with longer judgment time and reduce car safety accidents; fifth, small size and light weight can realize more compact and exquisite lamps, saving more space for other car designs; sixth, LED lights belong to the color Very good light source, no infrared, ultraviolet and other light, little heat and radiation, also suitable for automotive interior lighting, backlight application requirements.

However, the current LED headlights only have one lighting mode, and they all use white LEDs with high color temperature as the main lighting mode.

Light source, only when the visibility of the atmosphere is good, this kind of car light can be well applied. Compared with traditional yellow high-pressure sodium lamps, white LEDs with high color temperature have poor penetrating power to fog and haze in the atmosphere. If the weather changes, they cannot change with the visibility of the atmosphere, which seriously affects driving safety.

In addition, many drivers ignore the weather changes while driving, and do not turn on the fog lights and headlights in time, which brings extra burden to their eyes and increases driving fatigue.

Aiming at the above deficiencies, the utility model proposes an intelligent opening device for automobile LED lights, which can not only solve the driving safety in foggy weather, but also solve the problems of automatically turning on fog lights and headlights.
