LED automobile head lamp with adjustable angle and adjustable focal length

Abstract

The LED automobile head lamps sold in the present market have the technical disadvantages that the adjustable angle is not accurate enough or the interval of the adjustable angle is very small; the not enough accuracy of the adjustable angle is reflected in the large error angle of adjustment and the small interval of the adjustable angle is reflected in a very small adjustable angle, so that theLED automobile head lamps sold in the present market are not applicable to wide vehicle types and the error interval is usually the angle which achieves the best light effect; moreover, the prior LEDautomobile head lamps almost can not adjust the focal length; although the adjusting range of the focal length is small, but according to the feedback of manufacturers, the different vehicle types should achieve the best light effect. The objective of the invention is to provide an LED automobile head lamp with an adjustable angle and an adjustable focal length. By changing installing structures of a metal heat conducting body and a chuck, the LED automobile head lamp is convenient to install and capable of improving the accurate adjustment at the same time.

Description

technical field [0001] The invention relates to the technical field of automobile spare parts, in particular to an LED automobile headlight with adjustable angle and focal length. Background technique [0002] Along with social progress and economic development, people's living standards are getting higher and higher day by day, and automobiles have widely entered ordinary people's families. As an important part of the car, headlights can be called the eyes of the car, especially in night driving and bad weather conditions, it has an irreplaceable role in driving and ensuring driving safety. With the development of technology, car lights have undergone continuous technological upgrades, from halogen lamps to xenon lamps, to the latest LED lights, and the existing LED car headlights generally include LED light source boards for installing LED light sources The metal heat conductor of the plate, the chuck installed on the lampshade of the car headlight, the radiator, the rear...

Problems solved by technology

With the development of technology, car lights have undergone continuous technological upgrades, from halogen lamps to xenon lamps, to the latest LED lights, and the existing LED car headlights generally include LED light source boards for installing LED light sources The metal heat conductor of the plate, the chuck installed on the lampshade of the car headlight, the radiator, the rear end of the heat conductor is integrally formed with a mounting seat, the radiator is installed at the rear end of the mounting seat, and the heat conductor is fixed on the buckle, but now It is difficult to assemble and disassemble the heat conductor of the LED car headlight and the chuck, and the adjustment is inconvenient and inhumane. The design focus and production error of the light bowl manufacturer of the headlight assembly are uneven. Many car factories or maintenance points are in Feedback during installation, the lamp body needs to adjust a certain angle and focal length to achieve the best lighting effect

[0003] For example, in the Chinese invention patent of CN205877968U, the adjustable angle is not precise enough or the adjustable angle range is very small. It is not suitable for a wide range of car models. It is often the error range that is the angle that really achieves the best lighting effect. Moreover, the existing LED car headlights basically cannot adjust the focal length. Although the focal length adjustment range is small, but According to the feedback from the manufacturer, in order to achieve the best lighting effects for different models, the adjustable focus is very important. At the same time, when the installer replaces the headlights of the car, if the design accuracy of the parts is not high, it will also affect the normal use, which is very important. Inconvenient, therefore, the improvement of the structure of the car headlights allows the installer to quickly and conveniently match the headlights to different models when installing the headlights. This technology has become more important and practical
