Description

Technical Field

[0001] The present application relates to the field of waterproof structures, and in particular to a waterproof structure and a mining lamp with a variable beam angle using the waterproof structure. Background Art

[0002] Variable beam angle mining lamps are an important lighting equipment in the industrial production process. Compared with traditional mining lamps, variable beam angle mining lamps have the characteristics of adjustable beam angle (zoom) and are capable of adapting to different working areas and lighting needs.

[0003] In the related art, a variable beam angle mining lamp includes a lamp housing, an LED light board and a lens. The LED light board is installed in the mounting cavity of the lamp housing. The lens is connected to the LED light board through a zoom adjustment structure, so that the lens can be moved toward or away from the light board through the zoom adjustment structure, thereby realizing the adjustment of the beam angle of the mining lamp.

[0004] A waterproof structure is also provided between the lens of the variable beam angle mining lamp and the wall of the lamp housing installation cavity to prevent subsequent external water vapor from contacting and corroding the LED light board inside the lamp housing. The protective structure is specifically an O-ring installed on the periphery of the lens, and the periphery of the O-ring abuts against the wall of the lamp housing installation cavity to achieve a waterproof function.

[0005] Regarding the above-mentioned related technologies, on the one hand, the waterproof effect of the O-ring depends on its own dimensional accuracy, assembly tolerance and the roughness of the wall of the installation cavity of the lamp housing, and the waterproof effect is relatively limited. On the other hand, the waterproof performance of the waterproof structure is inversely related to the comfort of the lens when adjusting and moving. When the outer periphery of the O-ring is tightly attached to the wall of the installation cavity, it is easy to cause difficulty in moving the lens. Therefore, there is room for improvement. Utility Model Content

[0006] In order to improve the waterproof effect of the waterproof structure while reducing the influence of the waterproof structure on the adjustment and movement of the industrial and mining lamp lens, the present application provides a waterproof structure and a variable beam angle industrial and mining lamp using the waterproof structure.

[0007] The present application provides a waterproof structure and a variable beam angle mining lamp using the waterproof structure, which adopts the following technical solutions:

[0008] A waterproof structure comprises a flexible silicone sleeve, wherein a first connecting ring and a second connecting ring are coaxially arranged at both ends of the flexible silicone sleeve; the first connecting ring is used to connect to the top cavity wall of the mounting cavity of the lamp housing of a variable beam angle mining lamp, and the second connecting ring is used to connect to the lens of the variable beam angle mining lamp.

[0009] By adopting the above technical solution, when installing the waterproof structure of the variable beam angle mining lamp, the waterproof structure is sleeved on the periphery of the LED light board of the variable beam angle mining lamp, and the first connecting ring and the second connecting ring of the flexible silicone sleeve are respectively connected until the top wall of the installation cavity and the periphery of the lens. When the lens is subsequently moved to adjust the beam angle of the mining lamp, the LED light board is always located in the flexible protective sleeve, which effectively limits the external water vapor from contacting and corroding the LED light board. Compared with the traditional waterproof structure, the waterproof structure's own dimensional tolerance, installation accuracy and the roughness of the installation cavity wall affect the waterproof effect, thereby improving the waterproof effect of the waterproof structure. When the lens moves, the flexible silicone sleeve can be folded or contracted accordingly, which effectively reduces the influence of the waterproof structure on the adjustment and movement of the lens.

[0010] A variable beam angle industrial and mining lamp comprises the above-mentioned waterproof structure, and also includes a lamp housing, an LED light board and a lens, wherein the lamp housing is formed with an installation cavity; the LED light board is installed on the top cavity wall of the installation cavity; the lens is connected to the LED light board through a zoom adjustment structure; the flexible silicone sleeve is arranged on the periphery of the LED light board, the first connecting ring is connected to the top cavity wall of the installation cavity, and the second connecting ring is connected to the periphery of the lens.

At the same time, compared with the traditional O-ring, the flexible silicone sleeve can deform freely with the movement of the lens, maintaining the flexibility and comfort of the lens when adjusting and moving.

[0012] Preferably, a first annular limiting groove is formed on the top wall of the installation cavity, a first annular limiting protrusion is coaxially convexly formed on the upper surface of the first connecting ring, and the first annular limiting protrusion is embedded in the first annular limiting groove.

[0013] By adopting the above technical scheme, on the one hand, the first connecting ring of the flexible silicone sleeve is firmly connected to the top cavity wall of the lamp housing installation cavity; on the other hand, the first annular limiting protrusion and the first annular limiting groove cooperate to achieve sealing between the first connecting ring and the top cavity wall of the installation cavity, thereby limiting subsequent external water vapor from extending into the flexible silicone sleeve through the gap between the first connecting ring and the cavity wall of the installation cavity to corrode the LED lamp board.

[0016] Preferably, a first annular water-stopping protrusion is convexly provided on the top wall of the installation cavity; a first annular water-stopping groove is coaxially formed on the upper surface of the first connecting ring, and the first annular water-stopping protrusion is embedded in the first annular water-stopping groove.

[0017] By adopting the above technical solution, the cooperation between the first annular water-stopping protrusion and the first annular water-stopping groove is helpful to further improve the sealing between the first connecting ring and the top wall of the installation cavity.

[0018] Preferably, a second annular water-stopping protrusion is coaxially convexly provided on the lower surface of the lens, a second annular water-stopping groove is provided on the upper surface of the second connecting ring, and the second annular water-stopping protrusion is embedded in the second annular water-stopping groove.

[0019] By adopting the above technical solution, the cooperation between the second annular water-stopping protrusion and the second annular water-stopping groove is helpful to further improve the sealing between the second connecting ring and the lens.

[0020] Preferably, a connecting seat is provided on the top of the lamp housing, and a hanging ring is provided on the connecting seat.

[0021] By adopting the above technical solution, the mining lamp can be hung on the top of the building ceiling through the ring on the connecting seat when in use, which is convenient for installation and fixation of the mining lamp.

[0022] Preferably, a plurality of heat dissipation plates are vertically connected to the top of the lamp housing.

[0023] By adopting the above technical solution, it is convenient to increase the heat dissipation area of ​​the lamp housing through a plurality of heat dissipation plates, which is beneficial for the LED lamp board to better dissipate heat through the lamp housing during the subsequent use of the industrial and mining lamp.

A flexible silicone sleeve is installed on the periphery of the LED light board of the variable beam angle industrial and mining lamp, and the first connecting ring of the flexible silicone sleeve is connected to the top cavity wall of the lamp housing installation cavity, and the second connecting ring is connected to the lens. When the lens is subsequently moved toward or away from the LED light board to adjust the beam angle, the flexible silicone sleeve can be stretched or folded with the movement of the lens. During the movement of the lens, the LED light board is always located in the sealed cavity formed by the flexible silicone sleeve, the top cavity wall of the installation cavity and the lens. Compared with the traditional waterproof structure, on the one hand, the waterproof sealing effect of the waterproof structure is effectively improved, and on the other hand, the restriction of the waterproof structure on the movement of the lens is reduced.
