Description

Technical Field

[0001] The invention relates to the technical field of automobile lamps, in particular to an LED automobile lamp with good waterproof and sealing effect. Background Art

[0002] Headlights are a tool for illuminating the road at night, and are also a tool for issuing various vehicle driving signals.

[0003] Current automobile lamps usually seal the outer shell and lampshade to ensure the sealing of the lamp. When the lamp is working, high temperature will be generated, which will cause the internal air pressure of the equipment to increase, thereby forming a pressure difference between the inside and the outside. If the pressure difference cannot be eliminated in time, the stress formed inside the equipment will destroy the sealing performance of the equipment, causing damage to the lamp. Therefore, a plurality of ventilation holes are usually opened on the surface of the lamp shell to balance the pressure difference between the inside and outside of the lamp. Since a plurality of ventilation holes are opened on the surface of the lamp shell in the prior art, and the automobile lamp cannot close and open the ventilation holes according to the temperature of the lamp, that is, the usage condition, the waterproof sealing of the lamp is affected, and thus needs to be improved. Summary of the invention

[0004] The purpose of the present invention is to provide an LED automobile lamp with good waterproof sealing effect, which has the characteristics of effectively improving the waterproof sealing of the automobile lamp, quickly dissipating the heat of the lamp, and increasing the service life of the lamp.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an LED automobile lamp with good waterproof sealing effect, comprising a shell, a partition is installed inside the shell, a heat conducting plate is installed on the right side wall of the partition, a lamp holder is installed on the right side wall of the heat conducting plate, a lamp bead is installed on the outer side wall of the lamp holder, a plurality of heat conducting pipes penetrating the partition and fixedly connected to the partition are installed on the left side wall of the heat conducting plate, the left ends of the plurality of heat conducting pipes extend to the left side of the partition and a plurality of evenly distributed heat dissipating fins are installed through the outer side wall;

[0006] A ventilation hole is formed through the upper end of the left side wall of the partition, and sealing grooves are formed at the upper and lower ends of the ventilation hole. A fixing groove is formed in the sealing groove below, and a micro motor is installed inside the fixing groove. A ball located between the two sealing grooves is installed at the output end of the micro motor, and a ventilation hole is formed through the front end surface of the ball.

[0007] In order to accelerate the heat dissipation of multiple heat dissipation fins and heat pipes, as a preferred LED automobile lamp with good waterproof sealing effect of the present invention, a heat dissipation fan is installed through the left side wall of the shell.

[0008] In order to facilitate the discharge of the airflow in the shell and make the airflow in the shell flow, as a preferred LED car lamp with good waterproof sealing effect of the present invention, the left side wall of the shell is penetrated by two heat dissipation ports distributed up and down.

[0009] In order to facilitate the detection of the temperature inside the lampshade, as a preferred LED automobile lamp with good waterproof sealing effect of the present invention, a temperature sensor is installed on the right side wall of the partition.

[0010] In order to increase the sealing performance between the ball and the two sealing grooves and the inner walls of the ventilation hole, as a preferred LED automobile lamp with good waterproof sealing effect of the present invention, the inner walls of the two sealing grooves and the ventilation hole are both equipped with sealing gaskets abutting against the ball.

[0011] In order to seal the lampshade and the shell, as a preferred LED car lamp with good waterproof sealing effect of the present invention, the right side wall of the shell is provided with an installation groove, and the two side walls inside the two installation grooves are installed with sealing strips, and the lampshade is installed between the two sealing strips.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When the present invention is used, the partition plate and the lampshade seal the lamp bead in the shell, and the ball bearing closes the ventilation hole, thereby increasing the sealing performance of the car lamp, thereby effectively improving the waterproof sealing performance of the car lamp;

[0014] In the process of using the lamp beads, the heat conducting plate conducts the heat generated by the lamp beads to the multiple heat conducting tubes, so that the multiple heat conducting tubes conduct the heat to the multiple heat dissipation fins for heat dissipation, and the temperature sensor can monitor the temperature inside the lampshade. When the temperature sensor monitors that the temperature of the lampshade reaches the set value, the control device can start the cooling fan and the micro motor to speed up the heat dissipation of the multiple heat dissipation fins and heat conducting tubes. At the same time, the micro motor drives the ball to rotate 90 degrees to open the ventilation hole, eliminate the pressure difference between the inside and outside of the lampshade, and keep the pressure difference between the inside and outside of the lampshade balanced with the outside, thereby protecting the sealing of the car lamp and increasing the service life of the car lamp.

[0015] In summary, the device effectively improves the waterproof sealing of the automobile lamp while quickly dissipating the heat of the lamp, thereby increasing the service life of the lamp. BRIEF DESCRIPTION OF THE DRAWINGS
