Description

Technical Field

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

[0002] LED spotlights are widely used in people's lives, such as lighting in roads, bridges, stations, squares, gymnasiums and other occasions. As a lighting equipment, due to its wide range of applications, it has relatively high requirements for its waterproof performance, especially outdoors or in places with high air humidity. Otherwise, water vapor may enter the LED spotlight, damage the lighting electrical components in the LED spotlight, and reduce the service life of the LED spotlight.

[0003] The existing LED spotlights have poor waterproof effect, which makes the LED spotlight shell seriously affected by water, unable to be used normally, and greatly reduces the life span, thus limiting the promotion of LED spotlights. Especially when used outdoors or in humid places for a long time, it is easy to have quality problems due to the non-waterproof spotlight shell.

[0004] In the patent document with publication number CN213810220U, a waterproof LED spotlight is disclosed, in which a waterproof sealing ring is added at the installation position of the lens holder in the LED lamp bead installation groove, thereby increasing the waterproof performance of the waterproof LED spotlight, and a lens protrusion is provided at the bottom opening of the lens holder facing the reflective cup, thereby sealing the opening, thereby further enhancing the waterproof performance of the waterproof LED spotlight.

[0005] However, for the waterproof LED spotlight, water droplets will directly enter the lens seat and may accumulate on the surface of the lens seat, which will cause the sealing effect to decrease over time. Therefore, it is necessary to provide a waterproof LED spotlight with good sealing effect that can reasonably guide external water droplets. Utility Model Content

The reflector 202 is fixedly connected to one side of the limiting column 203. The transparent lampshade 201 is threadedly connected to the outer surface of the reflector 202. The inner wall of the transparent lampshade 201 is provided with an internal thread that cooperates with the external thread provided on the side of the reflector 202. The inner wall of the spotlight protective shell 2 is provided with an internal thread. After the transparent lampshade 201 and the reflector 202 are threadedly connected, a waterproof sealing ring 204 is installed to cooperate with the external thread provided on the side of the spotlight housing 3.

[0030] The buffer mechanism includes a limit plate 301, a spring mounting seat 1 302, a spring 303, a spring mounting seat 2 304, a spotlight mounting seat 305, a spotlight 306 and a vent hole 307. The limit plate 301 is fixedly connected to the inner wall of the spotlight housing 3, the spotlight mounting seat 305 is movably connected to the front of the limit plate 301, the spring mounting seat 1 302 is fixedly connected to one side of the inner wall of the spotlight housing 3, the spring mounting seat 2 304 is fixedly connected to one side of the spotlight mounting seat 305, and the spring 303 is movably connected between the spring mounting seat 1 302 and the spring mounting seat 2 304. There are six pairs of spring mounting seat 1 302, spring 303 and spring mounting seat 2 304 evenly distributed in front of the limit plate 301. When the spotlight 306 collides as a whole, the spotlight 306 fixedly installed inside the spotlight mounting seat 305 is protected. The spotlight 306 is movably connected to the inside of the spotlight mounting seat 305. A through hole is opened at the back of the spotlight protection shell 2. One side of the through hole is set as a slope, and the slope cooperates with the back of the reflector 202. The spotlight 306 as a whole has movable space on the through hole side of the inner wall of the spotlight protection shell 2, and the air vent 307 is opened on the side wall of the spotlight mounting seat 305.

[0031] Embodiment 2:

[0032] On the basis of the first embodiment, a support frame 4 is fixedly connected to one side of the top of the base 1, and a heat dissipation mechanism is arranged inside the support frame 4, and the heat dissipation mechanism includes a support column 401, a ventilation groove 402, a cooling fan 403, a heat sink 404, a limiting threaded rod 405, a rotating handle 406, an exhaust pipe 407, a waterproof breathable membrane 408 and a threaded hole 409, and the support column 401 is movably connected to the inner wall of the support frame 4, one side of the support column 401 is fixedly connected to the spotlight housing 3, and the other side is slidably connected to the inner wall of the support frame 4, the heat sink 404 is fixedly connected to the inner wall of the support column 401, the cooling fan 403 is fixedly connected to one side of the heat sink 404, the ventilation groove 402 is opened on one side of the support column 401, and the ventilation groove 402 are evenly opened on one side of the support column 401, and three threaded holes 409 are opened through one side of the support frame 4. The limiting threaded rod 405 is threadedly connected to the inner wall of the threaded hole 409, the exhaust duct 407 is fixedly connected to the back of the support frame 4, and the waterproof breathable membrane 408 is fixedly connected to the inner wall of the exhaust duct 407. The air holes 307 opened inside the spotlight mounting base 305, the heat generated by the spotlight 306 when working will be dissipated through the air holes 307. Under the action of the cooling fan 403, the heat is discharged from the air groove 402 through one end of the support column 401, and finally discharged from the exhaust duct 407. The waterproof breathable membrane 408 fixedly connected to the bottom of the exhaust duct 407 can conveniently discharge the heat.

[0033] The outer surface of the spotlight housing 3 is fixedly connected with a guide plate 5, which is evenly distributed on the outer surface of the spotlight housing 3. The side surface of the spotlight housing 3 is inclined, and the front diameter of the spotlight housing 3 is larger than the back diameter.

[0034] Working principle:

[0035] Firstly, the waterproof mechanism set up can effectively prevent rainwater from entering the spotlight housing 3 and causing the spotlight 306 to reduce its working life when the LED spotlight is working outdoors in rainy weather. The transparent lampshade 201 can drain rainwater when outdoors, guiding the rainwater to flow down the surface of the transparent lampshade 201. After the transparent lampshade 201 and the reflector 202 are threadedly connected, a waterproof sealing ring 204 is added to the outside, and finally the whole is pressed into the inside of the spotlight protective shell 2 to ensure that the limit column 203 is located on the inner wall of the slide groove 205. After rotating a certain angle, the sealing installation is completed.

[0036] Furthermore, a spotlight mounting base 305 is provided inside the spotlight housing 3, and the spotlight 306 can be stably mounted on the inner wall of the spotlight mounting base 305. When the spotlight as a whole collides, the force generated by the collision with the spotlight housing 3 will be transmitted to the spring 303. The spring 303 will shrink under the force and generate a rebound force under the action of its own restoring force, thereby offsetting the potential energy generated by the collision and effectively protecting the spotlight 306 fixedly mounted inside the spotlight mounting base 305.

[0037] Furthermore, the limiting threaded rod 405 can be driven to move by rotating the rotating handle 406. When loosening it outward, the angle of the spotlight housing 3 can be adjusted to facilitate the staff to adjust the appropriate angle for work. When tightening it, the support column 401 can be adjusted and fixed.

[0038] Furthermore, an air hole 307 is opened inside the spotlight mounting base 305. When the spotlight 306 is working, heat is generated and dissipated through the air hole 307. Under the action of the cooling fan 403, the heat is dissipated through the air groove 402 at one end of the support column 401 and finally discharged through the exhaust duct 407. A waterproof and breathable membrane 408 is fixedly connected to the bottom of the exhaust duct 407 to facilitate the discharge of heat.
