Description

Technical Field

[0001] This utility model belongs to the field of LED vehicle lighting technology, specifically, it relates to an LED heat dissipation automotive light with adjustable lighting range. Background Technology

[0002] With the rapid development of automotive lighting, more and more models are equipped with automatic leveling adjustment. Currently, common dimming mechanisms include a dimming screw, a height adjustment mechanism, a support rail on the housing, and a ball joint. The dimming screw is mounted on the housing, with one end outside the housing (the input end for adjustment force) and the other end inside the housing, fixed by a spring clip and the height adjustment mechanism. The height adjustment mechanism is connected and fixed to the lens bracket via a ball joint mounted in the ball joint. However, the dimming screws used in this type of dimming mechanism have a structural problem: typically, there are 1-2 dimming screws, driven by a motor to move back and forth, causing the entire lamp holder to make minor adjustments. Therefore, during dimming, the dimming screw can only move the light source back and forth, resulting in a small adjustment angle and limited control over the range of light illumination, thus limiting flexibility.

[0003] Therefore, there is an urgent need for a type of vehicle headlight that can further adjust the angle of the lamp holder and improve the range of lighting adjustment. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide an LED heat dissipation car headlight with adjustable illumination range, so as to avoid the trouble of the previous headlights having a small adjustment angle and limited illumination range.

[0008] A light guide cover that encloses LED beads;

[0009] The upper support base is installed on the upper side of the fin section. The ball head guide sleeve base is fixed on the left and right sides of the upper support base by screws. The ball head guide sleeve base is provided with multiple positioning grooves. The ball head guide sleeve base is installed with a ball head shaft. The ball head end of the ball head shaft is provided with a positioning block that is embedded in the positioning groove.

[0010] The lower ball head base is installed on the lower side of the fin section and is located at the left and right ends. The lower ball head base is equipped with the lower ball head screw.

[0011] According to one embodiment of the present invention, the ball head shaft and the lower ball head screw are respectively driven by a motor, wherein the ball head shaft drives the heat dissipation base to deflect left and right, and the lower ball head screw drives the heat dissipation base to deflect back and forth.

[0012] According to one embodiment of the present invention, the tail end of the ball head shaft is configured as a non-circular shaft handle, and the tail end of the lower ball head screw is configured as an external thread.

[0013] According to one embodiment of the present invention, the heat dissipation base is configured as an aluminum heat dissipation base.

[0014] According to one embodiment of the present invention, the lower end of the heat dissipation base is provided with a connector for electrically connecting to the LED light board.

[0015] Compared with the prior art, the present invention can achieve the following technical effects:

[0016] The LED light panel is directly mounted on the heat dissipation base to improve heat dissipation; at the same time, three sets of ball head adjustment components are set on the back of the heat dissipation base to drive the entire heat dissipation base to tilt left, right and forward and backward, thereby improving the adjustability of the lighting range and making it convenient and practical.

Detailed Implementation

[0024] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0026] As shown in the figure, an LED heat dissipation automotive light with adjustable illumination range includes: a heat dissipation base 10, with a flat plate 11 on the front and a finned portion 12 on the rear; an LED lamp plate 20 fixed to the flat plate 11 by screws, the LED lamp plate 20 having LED beads; a light guide cover 30 covering the LED beads; an upper raised base 40 installed on the upper side of the finned portion 12, with ball head guide sleeve bases 50 fixed to the left and right sides of the upper raised base 40 by screws, the ball head guide sleeve bases 50 having multiple positioning grooves 51 around them, a ball head shaft 60 installed on the ball head guide sleeve bases 50, and a positioning block 61 embedded in the positioning groove 61 at the ball head end of the ball head shaft 60; and a lower ball head base 70 installed on the lower side of the finned portion 12 and located at the left and right ends, with a lower ball head screw 80 installed on the lower ball head base 70.

[0027] In one embodiment of this utility model, the heat dissipation base 10 is an aluminum heat dissipation base, which has good heat dissipation performance. Its front side is a flat plate 11 for mounting the LED light board 20; the rear side is a finned part 12, forming an efficient heat dissipation. The LED light board 20 uses LED beads as the light source, which has good luminous efficiency. The light guide cover 30 is a transparent PC part, which can effectively guide light and improve the illumination range.

[0028] Dimming components are provided on the upper and lower sides of the fin section 12. Specifically, two sets of lower ball head bases 70 are provided on the lower left and right sides of the fin section 12, and lower ball head screws 80 are installed in conjunction with them.

Figure 3For ease of illustration, both are deflected. The ball joint shaft 60 and the ball joint guide sleeve base 50 are engaged with each other by the positioning groove 51 and the positioning block 61, so that when the ball joint shaft 60 rotates, the entire ball joint guide sleeve base 50 rotates with it, thereby realizing the upper angle adjustment of the heat dissipation base 10, which can increase the range of adjustment of the lighting range, and cooperate with the lower ball joint screw 80 to improve flexibility.

[0030] The ball joint shaft 60 and the lower ball joint screw 80 of this utility model are driven by motors. The ball joint shaft 60 drives the heat dissipation base 10 to deflect left and right, and the lower ball joint screw 80 drives the heat dissipation base 10 to deflect back and forth, which is convenient and practical.

[0031] Preferably, the tail end of the ball head shaft 60 is configured as a non-circular shaft handle, directly forming a rotating operation; the tail end of the lower ball head screw 80 is configured as an external thread, which cooperates with the threaded sleeve to complete axial operation.

[0032] In addition, the lower end of the heat sink 10 is provided with a connector 90 for electrically connecting to the LED light board 20, which facilitates the connection of the LED light board 20 and ensures good stability.

[0033] In summary, this utility model improves heat dissipation by directly mounting the LED light board 20 on the heat dissipation base 10; at the same time, three sets of ball head adjustment components are set on the rear side of the heat dissipation base 10 to drive the entire heat dissipation base 10 to tilt left and right and back and forth, thereby improving the adjustability of the lighting range and making it convenient and practical.
