Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamps, in particular to a waterproof LED automobile lamp. Background Art

[0002] LED car lights refer to the light sources inside and outside the car that use LED technology, and are used for external and internal lighting. Since LED car lights will appear on rainy days or directly wash away stains on the surface of the car, the waterproofness of the exterior of the car is extremely high, especially the lighting lamps on the outside of the car. The lighting lamps involve a large number of circuit devices. Once water seepage occurs, it is easy for the electronic devices inside the car lights to short-circuit, and eventually burn out and cannot be used normally. It is easy to be dangerous if the car lights are damaged on rainy nights.

[0003] In addition, in rainy weather, the temperature will drop. During the lighting process, if the LED car lights are set to a closed state to prevent water from seeping in, it will be difficult to dissipate heat. The temperature around the car lights will rise, and it will be easy for water vapor to form on the car lampshade, affecting the lighting.

[0004] Based on the above problems, there is an urgent need for a waterproof LED automobile lamp that can prevent water mist from being generated on the automobile lampshade. Utility Model Content

[0005] With respect to the current waterproof LED lamp body, when the temperature difference between the inside and outside of the lamp is large, it is easy to cause water mist to be generated on the lampshade of the car. The present application provides a waterproof LED car lamp to solve the above problem.

[0006] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] The embodiment of the present application discloses a waterproof LED automobile lamp, comprising a lamp body, wherein the rear side of the lamp body is fixed by a fixing seat, a light-transmitting lampshade is arranged on the front side of the lamp body, the fixing seat and the light-transmitting lampshade are sealingly connected by a heat-conducting copper ring, the heat-conducting copper ring is recessed inwardly and forms a first groove between the fixing seat and the light-transmitting lampshade, and a water accumulation groove is arranged on the side wall of the heat-conducting copper ring arranged between the fixing seat and the light-transmitting lampshade.

[0008] Optionally, a first snap-in is provided at the contact point between the fixed seat and the light-transmitting lamp cover and the thermally conductive copper ring, which is first bent vertically inward and then bent laterally outward; a second snap-in is provided at the contact point between the thermally conductive copper ring and the fixed seat and the light-transmitting lamp cover, which is first bent vertically outward and then bent laterally inward; the first snap-in and the second snap-in are snapped into each other and are sealed by glue.

[0009] Optionally, a water blocking plate is provided at the bottom of the water trough, the water blocking plate is arranged in the first groove, and the two ends of the water blocking plate are fixedly connected to the light-transmitting lampshade and the fixing seat respectively through springs; the spring is close to the side wall of the first groove.

[0010] Optionally, the top surface of the heat-conducting copper ring is high in the middle and low on both sides.

[0011] Optionally, the water blocking plate includes a first plate body and a second plate body that are symmetrically arranged, with a gap between the first plate body and the second plate body; ends of the first plate body and the second plate body are respectively rotatably connected to the fixing seat and the light-transmitting cover through a rotating shaft.

[0014] The beneficial effects of the utility model are:

[0015] The present application arranges a heat-conducting copper ring between the light-transmitting lampshade and the fixing seat. In the rainy season, due to the temperature drop and the heat radiated to the surrounding by the lamp body during lighting, the heat-conducting copper ring can quickly conduct heat, and the first groove formed on the heat-conducting copper ring can make water gather along the first groove to continuously dissipate the heat of the lamp body, thereby reducing the temperature difference between the inside and outside of the lampshade, preventing the outflow of water from the lampshade, and continuously consuming the heat energy conducted by the copper ring, thereby reducing the fog in the lampshade.

[0022] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0023] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0024] See also Figure 1-Figure 3 , for example, the original waterproof LED lamp body 1 is sealed with the outer contact surface. During lighting at rainy nights, the heat emitted by the lamp body 1 will continuously gather between the lamp body 1 and the lampshade. Since the external temperature is low, it is easy to form water mist inside the lampshade, affecting the lighting of the lamp body 1. Based on this, the embodiment of the present application discloses a waterproof LED automobile lamp, including a lamp body 1, the rear side of the lamp body 1 is fixed by a fixing seat 2, a translucent lampshade 3 is arranged on the front side of the lamp body 1, the fixing seat 2 and the translucent lampshade 3 are sealedly connected by a heat-conducting copper ring 4, the heat-conducting copper ring 4 is recessed inwardly and forms a first groove 5 between the fixing seat 2 and the translucent lampshade 3, for The accumulated water enters the first groove 5, and the translucent lampshade 3 and the fixing seat 2 are sealed by the heat-conducting copper ring 4, as shown in the figure, and the heat-conducting copper ring 4 is concave inward between the translucent lampshade 3 and the fixing seat 2 on both sides to form the first groove 5, and the side wall of the heat-conducting copper ring 4 arranged between the fixing seat 2 and the translucent lampshade 3 is provided with a water accumulation groove 6. When it rains, rainwater will gather in the first groove 5 and flow down, and the heat-conducting copper ring 4 will continuously flow through with the rainwater after heat conduction to transfer heat, and will continuously discharge the heat emitted by the lamp body 1 collected in the translucent lampshade 3 and the fixing seat 2 to the outside, thereby reducing the temperature difference between the LED car light and the outside, thereby preventing fog from forming on the inner wall of the translucent lampshade 3.

[0025] The contact point between the fixing seat 2 and the light-transmitting lampshade 3 and the heat-conducting copper ring 4 is provided with a first bayonet 7 that is first bent vertically inward and then bent horizontally outward, and the contact point between the heat-conducting copper ring 4 and the fixing seat 2 and the light-transmitting lampshade 3 is provided with a second bayonet 8 that is first bent vertically outward and then bent horizontally inward, and the first bayonet 7 and the second bayonet 8 are mutually engaged and sealed by glue. As shown in the engaging method in the figure, when rainwater flows through the gap between the heat-conducting copper ring 4 and the fixing seat 2 and the light-transmitting lampshade 3, it will not flow into the gap due to gravity, and even if the glue between the heat-conducting copper ring 4 and the fixing seat 2 and the light-transmitting lampshade 3 is partially destroyed, it is difficult for the rainwater to partially deposit and penetrate into the inside of the LED car lamp.

[0026] A water blocking plate 9 is provided at the bottom of the water trough 6, and the water blocking plate 9 is provided in the first groove 5, and the two ends of the water blocking plate 9 are respectively fixedly connected to the light-transmitting lampshade 3 and the fixing seat 2 through springs 10. The spring 10 is close to the side wall of the first groove 5; by adopting the above technical scheme, the water blocking plate 9 will block the flow of rainwater in the first groove 5, and make the water continuously gather in the groove, which can achieve more effective heat conduction, so that the rainwater absorbs most of the heat absorbed by the heat-conducting copper ring 4. As the amount of rainwater collected increases, the spring 10 is pressed downward by gravity, pressing the water blocking plate 9 to continuously drop until it is far away from the first groove 5, and all the rainwater is discharged for the next time, and the rainwater continues to accumulate for heat conduction.

[0027] The top surface of the heat-conducting copper ring 4 is high in the middle and low on both sides. With this solution, when rainwater accumulates on the top surface of the heat-conducting copper ring 4, it will flow down quickly toward both sides due to gravity, and will not seep due to the accumulation of rainwater.

[0028] The water blocking plate 9 includes a first plate body 11 and a second plate body 12 that are symmetrically arranged, with a gap between the first plate body 11 and the second plate body 12; the ends of the first plate body 11 and the second plate body 12 are rotatably connected to the fixing seat 2 and the light-transmitting cover respectively through a rotating shaft 13. This solution can achieve the rainwater to flow down slowly, and the more rainwater accumulates, the larger the opening between the plates, and the faster the rainwater flow rate, thereby preventing excessive rainwater accumulation from causing water seepage.

[0029] The side walls of the fixing seat 2 and the light-transmitting lampshade 3 are respectively provided with a second groove 14 , the depth of the second groove 14 and the first groove 5 are at the same level, the height of the second groove 14 is lower than that of the first groove 5 , and the second groove 14 is connected to the first groove 5 .

[0030] By adopting the above technical solution, when a lot of rainwater is accumulated in the first groove 5, the accumulated rainwater will flow through the second groove 14. There is no obstruction in the second groove 14, and the rainwater can pass through quickly.

[0031] A plurality of drainage pipes 15 are arranged in the first groove 5 , and the drainage pipes 15 are arranged in a multi-section bending shape.

[0032] The drainage pipe 15 is arranged in a multi-section bend shape, which can ensure that the drainage pipe 15 is in full contact with the heat-conducting copper ring 4, absorbs heat and then discharges rainwater.

[0033] Unless otherwise specified, the device components involved in the above embodiments are all conventional device components, and the connection methods and control methods involved are all conventional connection methods and control methods unless otherwise specified.

[0034] The present invention has been described in detail above in conjunction with the embodiments. However, those skilled in the art will appreciate that, without departing from the spirit of the present invention, the specific parameters in the embodiments described above may be changed to form a plurality of specific embodiments, which are all within the common variation range of the present invention and will not be described in detail herein.
