Abstract
Description
Technical Field
[0001] This invention relates to an automotive LED lighting fixture, and more particularly to an all-weather waterproof and dustproof automotive LED lighting fixture. Background Technology
[0002] With the development of the automotive industry and the increasing demands for driving safety, automotive LED lights have been widely used due to their advantages such as high brightness, low energy consumption, and long lifespan. However, a major challenge for automotive LED lights during use is how to effectively dissipate heat while maintaining good waterproof and dustproof performance. Especially in harsh weather conditions, such as rain or muddy roads, water and dust can easily enter the heat sink of the headlights. This not only reduces the lighting effect of the lights but may also damage the internal electronic components, affecting their lifespan.
[0003] To meet heat dissipation requirements, most automotive LED lights on the market currently incorporate heat dissipation meshes or vents into their design and are equipped with fans to enhance airflow. However, this design has the following problems:
[0004] Insufficient waterproofing: Traditional heat dissipation mesh or vents lack effective waterproofing measures. When exposed to rain or other water sources, moisture may enter the lamp through these openings, causing short circuits or damage to the lamp.
[0005] Poor dustproof performance: Although some lamps use sealing rings or sealants to try to prevent dust from entering, after long-term use, a small amount of dust will still accumulate inside the lamp through the heat dissipation mesh or heat dissipation holes, affecting light output efficiency and heat dissipation performance.
[0006] High maintenance costs: Due to the reasons mentioned above, the lighting fixtures require regular inspection and cleaning, increasing maintenance costs and workload. Furthermore, the cost of repairing or replacing fixtures damaged internally is also high.
[0007] Therefore, there is an urgent need to develop an all-weather waterproof and dustproof automotive LED lighting system to solve the aforementioned technical problems. Summary of the Invention
[0008] In order to overcome the shortcomings of the prior art, the present invention provides an all-weather waterproof and dustproof automotive LED lighting lamp.
[0009] The technical implementation scheme of the present invention is as follows: an all-weather waterproof and dustproof vehicle LED lighting lamp, comprising a rear part and a front part, which are connected by adhesive bonding. The rear part includes a rear lamp cover, a dustproof and waterproof part, and an LED lamp. The LED lamp is disposed on the rear side of the rear lamp cover. The dustproof and waterproof part is disposed on the rear lamp cover outside the LED lamp. The dustproof and waterproof part includes a protective cover, a waterproof and breathable membrane I, a mounting plate, a miniature fan, a slider, an arc-shaped track, a T-shaped screw, and a nut I. The protective cover is disposed on the rear lamp cover outside the LED lamp and communicates with the rear lamp cover. The mounting plate is concentrically connected to the protective cover via an axis. The waterproof and breathable membrane I is disposed at the lower part of the protective cover. At least two miniature fans are fixedly connected to the mounting plate. Arc-shaped tracks are disposed on both the front and rear sides of the protective cover. The sliding grooves on the arc-shaped tracks are T-shaped. T-shaped screws are slidably connected in the arc-shaped tracks. Sliders are disposed on both the front and rear sides of the protective cover. The T-shaped screws pass through the sliders and are connected to the nut I by bolts.
[0010] As a further preferred option, the mounting plate has a concave hole through which the protective cover passes.
[0011] As a further preferred option, the sliding groove on the arc track is T-shaped.
[0012] As a further preferred solution, the front part of the lamp includes a front lamp cover and a sealing strip. The front lamp cover and the rear lamp cover are fixedly connected by adhesive bonding. A sealing strip is provided at the position where the front lamp cover contacts the automotive sheet metal.
[0013] As a further preferred option, it also includes guide rails, irregularly shaped covers, cylindrical screws, nuts II, and waterproof and breathable membrane II. Guide rails are symmetrically arranged on the front and back of the right side of the protective cover. Irregularly shaped covers are slidably connected between the guide rails. The irregularly shaped covers are on the right side of the waterproof and breathable membrane I. The front and back sides of the irregularly shaped covers are inside the guide rails. Cylindrical screws are provided on the irregularly shaped covers inside the guide rails. The cylindrical screws pass through the guide rails and are connected to nuts II by threads. Waterproof and breathable membrane II is provided at the outlet of the irregularly shaped covers.
[0014] As a further preferred option, there is a certain gap between the inner side of the guide rail and the outer surface of the protective cover, and the middle of the guide rail is hollow.
[0015] As a further preferred option, the upper part of the irregularly shaped cover is a downward sloping surface, and the lower part of the irregularly shaped cover is a slope that first slopes upward and then downward, so that the lower side of the irregularly shaped cover has an upward arching slope.
[0016] As a further preferred option, a breathable sponge is also included, with a breathable sponge detachably connected to the outlet of the irregularly shaped cover, and the breathable sponge is on the left side of the waterproof and breathable membrane II.
[0017] The beneficial effects of this invention are as follows: The invention uses a mounting plate to drive a miniature fan, allowing for angle adjustment. This adjusts the angle at which the miniature fan absorbs hot air, improving heat dissipation for the vehicle headlights without affecting light projection and facilitating airflow, thus helping to quickly remove heat from the light source. The exhaust direction of the miniature fan can be adjusted, preventing the outlet below the protective cover from being directly exposed to water flow. This design maintains good heat dissipation while reducing the risk of water intrusion. The angle of the outlet of the irregularly shaped cover can be adjusted, allowing for the regulation of the heat dissipation outlet. This allows the outlet position to be adjusted to the optimal waterproof and dustproof position, further enhancing the waterproof and dustproof performance of the vehicle headlights.

[0030] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.
[0031] Example: An all-weather waterproof and dustproof automotive LED lighting lamp, such as... Figures 1-11As shown, the lamp includes a rear part 1 and a front part 2, which are connected by adhesive bonding. The rear part 1 includes a rear lamp cover 102, a dustproof and waterproof part 101, and an LED light 103. The LED light 103 is located on the rear side of the rear lamp cover 102. The dustproof and waterproof part 101 is located on the rear lamp cover 102 outside the LED light 103. The dustproof and waterproof part 101 includes a protective cover 1011, a waterproof and breathable membrane I 1011a, a mounting plate 1012, a miniature fan 1013, a slider 1014, an arc-shaped track 1015, and a T-shaped screw 1016. With nut I1017, a protective cover 1011 communicating with the rear lamp cover 102 outside the LED lamp 103 is provided on the rear lamp cover 102. A mounting plate 1012 is concentrically connected to the protective cover 1011 via a shaft. A concave hole is opened on the mounting plate 1012, through which the protective cover 1011 passes. A waterproof and breathable membrane I1011a is provided at the lower part of the protective cover 1011. At least two miniature fans 1013 are fixedly connected to the mounting plate 1012 by bolts. The miniature fans 1013 exhaust heat by air intake. The front and rear sides of the cover 1011 are provided with arc-shaped tracks 1015. The sliding grooves on the arc-shaped tracks 1015 are T-shaped, and T-shaped screws 1016 are slidably connected inside the arc-shaped tracks 1015. The front and rear sides of the protective cover 1011 are provided with sliders 1014. The sliders 1014 and T-shaped screws 1016 partially overlap in the front-rear direction. The T-shaped screws 1016 pass through the sliders 1014 and are connected to nuts I 1017 by bolts. When installing the vehicle light, first loosen the nuts I 1017, and then rotate the mounting plate 1012 to drive the miniature fan 1013 to rotate. The angle of the micro fan 1013 can be adjusted to better dissipate heat from the headlights without affecting light projection and facilitating airflow. This helps to quickly remove heat from the light source. The exhaust direction of the micro fan 1013 can be adjusted so that the exhaust heat can be guided along the protective cover 1011 to the waterproof and breathable membrane I 1011a below. The outlet below the protective cover 1011 is not easily exposed to the direction of water flow. This design can reduce the risk of water intrusion while maintaining good heat dissipation.
[0032] like Figure 3 As shown, the front part 2 of the lamp includes a front lamp cover 201 and a sealing strip 202. The front lamp cover 201 and the rear lamp cover 102 are fixedly connected by adhesive. The sealing strip 202 is provided at the position where the front lamp cover 201 contacts the automotive sheet metal. After the front lamp cover 201 is installed, the sealing strip 202 can make the front lamp cover 201 fit more tightly with the automotive sheet metal, which can prevent moisture and dust from entering from the front.
[0033] like Figure 4 , Figure 9 and Figure 10As shown, it also includes guide rails 1018, irregularly shaped covers 1019, columnar screws 1020, nuts II 1021, and waterproof and breathable membrane II 1022. Guide rails 1018 are symmetrically arranged on the front and back of the right side face of the protective cover 1011. There is a certain gap between the inner surface of the guide rails 1018 and the outer surface of the protective cover 1011. The middle part of the guide rails 1018 is hollow. Irregularly shaped covers 1019 are slidably connected between the guide rails 1018. The upper part of the irregularly shaped cover 1019 is a downward-sloping surface, and the lower part of the irregularly shaped cover 1019 is a slope that first slopes upward and then downward, giving the lower surface of the irregularly shaped cover 1019 an upward arched slope. The irregularly shaped cover 1019 is on the right side of the waterproof and breathable membrane II 1011a, and its front and back sides are inside the guide rails 1018. Each of the irregularly shaped covers 1019 inside the track 1018 is equipped with a columnar screw 1020. The columnar screw 1020 passes through the guide track 1018 and is connected to a nut II 1021 by thread. A waterproof and breathable membrane II 1022 is provided at the outlet of the irregularly shaped cover 1019. By loosening the nut II 1021, the angle of the outlet of the irregularly shaped cover 1019 can be adjusted, so that the outlet for heat dissipation can be adjusted. This allows the outlet position to be adjusted to the optimal waterproof and dustproof position, further improving the waterproof and dustproof effect of the vehicle headlight. After the angle of the irregularly shaped cover 1019 is adjusted, the nut II 1021 is tightened to fix the position of the irregularly shaped cover 1019. The bottom of the irregularly shaped cover 1019 is sloped, so if dust and water vapor want to enter, they need to climb the slope, which can block dust and water vapor.
[0034] like Figure 9 and Figure 11 As shown, it also includes a breathable sponge 1023. The breathable sponge 1023 is detachably connected to the outlet of the irregular cover 1019. The breathable sponge 1023 is on the left side of the waterproof and breathable membrane II 1022. The breathable sponge 1023 can absorb the water vapor entering the irregular cover 1019, and at the same time, the hot air that comes out can dry the water vapor on the breathable sponge 1023.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
