Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a waterproof encapsulation structure for outdoor LED lighting fixtures. Background Technology

[0002] Outdoor LED lighting fixtures are lighting devices specifically designed for outdoor environments and are widely used in public places such as streets, parks, squares, and building facades. Compared with traditional lighting fixtures, LED lighting fixtures use light-emitting diodes as the light source, offering advantages such as high energy efficiency, long lifespan, fast start-up, and low heat generation. Outdoor LED lighting fixtures not only provide ample illumination but also feature environmental friendliness and energy saving, effectively reducing energy consumption and carbon emissions. Due to their reliability and durability, outdoor LED lighting fixtures are increasingly favored in urban infrastructure construction and landscape lighting. To cope with complex and changing external environments, especially factors such as rain, humidity, and pollution, the waterproof encapsulation structure of outdoor LED lighting fixtures is particularly important.

[0003] Patent CN213577415U discloses a waterproof encapsulation structure for an LED lamp, including a mounting plate, a connecting plate, a lamp housing, a lamp holder, and a lamp cover. Two connecting plates are symmetrically arranged at the bottom of the mounting plate, each with a through hole. The lamp housing is located between the two connecting plates. Two connecting posts are integrally formed on the outer walls of both sides of the connecting plates, rotating within the through slots of the connecting plates. A lamp holder is fixed inside the lamp cover by bolts, and multiple bulbs are installed at the bottom of the lamp holder. The lamp cover is located at the bottom of the lamp housing, and a sealing ring is adhered to the surface of the lamp cover. Two mounting grooves are symmetrically formed on the surface of the lamp housing, and heat-conducting blocks are adhered to the mounting grooves of the lamp housing, fitting snugly against the lamp holder. This waterproof encapsulation structure for LED lamps not only ensures the airtightness of the lamp cover, effectively preventing waterproofing and fogging, but also has good heat dissipation performance and strong practicality.

[0004] In existing technologies, the sealing ring installed between the lampshade and the lamp housing, as well as the sealing strip between the heat-conducting block and the lamp housing, effectively ensures the airtightness of the lamp housing, thus achieving waterproofing and anti-fogging effects. Furthermore, this design also exhibits good heat dissipation performance. However, the connection structure using fixed springs, fixed pins, and locking slots makes it impossible to disassemble the lampshade, causing inconvenience for later maintenance and repair. If the lampshade or internal bulb malfunctions, it is difficult for users to disassemble the lampshade for repair. Therefore, we propose a waterproof encapsulation structure for outdoor LED lighting fixtures. This structure, while ensuring waterproof performance, optimizes the lampshade disassembly method, making maintenance and replacement more convenient, thereby improving overall practicality and user experience.

[0028] Please see Figures 1-6 This utility model provides a technical solution:

[0029] The outdoor LED lighting fixture waterproof encapsulation structure includes a lamp housing 100, which serves as the external protective structure for the entire lighting fixture, providing rigidity and support to prevent external environmental factors from affecting internal components. A circuit board 200 is located on the top of the inner wall of the lamp housing 100, connecting and controlling LED beads 300 and providing power and signal transmission. Wires of the circuit board 200 pass through the inner wall of the lamp housing 100, and the connection points between the wires and the lamp housing 100 are sealed, such as with rubber rings, to provide waterproofing and dustproofing. Multiple LED beads 300 are located at the bottom of the circuit board 200. A reflector 500 is located inside the lamp housing 100, reflecting and concentrating light to improve lighting efficiency. A lamp shade 600 is located at the bottom of the lamp housing 100, with a rubber gasket 700 at the outer edge of the top of the lamp shade 600. The rubber gasket 700 seals the seam between the lamp shade 600 and the lamp housing 100 to prevent moisture and dust from penetrating.

[0030] The lamp housing 100 has connecting side blocks 110 on both the left and right sides. The connecting side blocks 110 are used to fix the lamp cover 600 and provide connection support. The bottom of the connecting side blocks 110 has a connecting hole 111 for the threaded rod 630 to pass through, so as to realize the detachable connection of the lamp cover 600. The middle of the left and right sides of the lamp cover 600 has a fixing protrusion 620. The fixing protrusion 620 is used to provide a fixing point for the lamp cover 600. The top of the fixing protrusion 620 has a threaded rod 630. The threaded rod 630 is used to cooperate with the wing nut 640 to realize the quick installation and removal of the lamp cover 600. The threaded rod 630 passes through the connecting hole 111 and is threadedly connected to the wing nut 640. The wing nut 640 is used for manual tightening, which facilitates the removal of the lamp cover 600 during maintenance.

[0031] In this embodiment, the top of the lamp housing 100 is provided with two L-shaped mounting bases 120 arranged symmetrically from left to right. The top of the L-shaped mounting base 120 is provided with multiple waist-shaped holes 121. The L-shaped mounting base 120 is used to provide mounting and fixing points for the lamp and is suitable for different installation scenarios.

[0032] Specifically, a T-shaped heat-conducting plate 400 is provided through the top of the lamp housing 100, and the bottom of the T-shaped heat-conducting plate 400 is in contact with the circuit board 200. The T-shaped heat-conducting plate 400 is used to conduct the heat generated by the circuit board 200 to the outside, thereby improving the heat dissipation efficiency.

[0033] Furthermore, a second frame-shaped rubber 900 is provided at the connection between the T-shaped heat-conducting plate 400 and the lamp housing 100. The second frame-shaped rubber 900 is used to seal the gap between the T-shaped heat-conducting plate 400 and the lamp housing 100 to prevent moisture from seeping in.

[0034] Furthermore, the top of the T-shaped heat-conducting plate 400 is provided with multiple heat sinks 410 arranged equidistantly from left to right. The heat sinks 410 are used to increase the heat dissipation area, accelerate heat dissipation, and ensure stable operation of the lamp.

[0035] Furthermore, the top of the lampshade 600 is provided with a frame-shaped positioning plate 610. The outer wall of the frame-shaped positioning plate 610 is attached to the inner wall of the lamp housing 100. The frame-shaped positioning plate 610 is used to position the relative position of the lampshade 600 and the lamp housing 100 to ensure assembly accuracy. The top of the frame-shaped positioning plate 610 is attached to the bottom of the reflector 500.

[0036] Furthermore, a groove 611 is provided on the top of the outer wall of the frame-shaped positioning plate 610. A first frame-shaped rubber 800 is bonded in the groove 611.

Then, the circuit board 200 connects to the power supply via wires and controls the LED beads 300 to emit light. The reflector 500 concentrates the light to improve lighting efficiency. The lamp cover 600 passes through the connecting hole 111 of the connecting side block 110 via the threaded rod 630 of the fixing protrusion 620, and is manually tightened by the wing nut 640. The rubber gasket 700 and the first frame-shaped rubber 800 together form a double seal to prevent moisture and dust intrusion. The T-shaped heat-conducting plate 400 contacts the circuit board 200, conducting heat to the heat sink 410 for dissipation. The second frame-shaped rubber 900 seals the joint between the heat-conducting plate and the lamp housing 100. During routine maintenance, the lamp cover 600 can be disassembled by loosening the wing nut 640 to directly inspect the internal components. After repair, it can be re-tightened to restore waterproof performance.
