Abstract
Description
Technical Field
[0001] The utility model relates to the field of LED lights, and particularly relates to a moisture-proof LED light board. Background Art
[0002] An LED light board is a lighting device that uses light-emitting diodes (LEDs) as light sources. With its characteristics of high efficiency, energy saving, long life, and environmental protection, the LED light board has been widely used in the lighting field. Traditional LED panel lights do not have moisture-proof sealing measures. In a humid environment, especially in places like bathrooms where water splashing and water droplets are likely to occur, the circuit board will get damp, resulting in the lamp not working properly or the lighting effect deteriorating.
[0003] For example, a moisture-proof LED panel light proposed in the patent application No. 202121148707.9 has a first sealing ring and a second sealing ring at the annular convex block of the lamp base. When the lamp base is screwed to the lamp cover, it provides sufficient sealing to prevent humid air from entering the interior of the LED panel light. A moisture-proof sheet is pasted inside the lamp base, and an annular moisture-proof sheet is also pasted on the bottom wall of the annular convex block to dehumidify the humid air entering the interior of the LED panel light, avoiding the phenomenon of fogging inside the lamp cover and also preventing the damage of the humid air to the substrate. A moisture-proof plug is provided at the threaded through hole to protect the screws in the threaded through hole from moisture, ensuring the tight connection between the lamp base and the lamp shell, improving the moisture-proof performance of the LED panel light, and thus extending the service life of the LED panel light.
[0004] However, although the above design plays a role in moisture-proofing, excessive sealing also hinders the air circulation and the heat dissipation performance of the LED lamp. Summary of the Utility Model
[0005] In order to solve the problems in the above background art, the utility model provides a moisture-proof LED light board, which can not only play a role in moisture-proofing, but also help the LED light board dissipate heat and extend the service life of the LED light board.
[0006] The solution adopted by the utility model to solve its technical problems is: a moisture-proof LED light board, including a base, an LED component fixed on the top of the base, and a protective cover. The protective cover wraps around the outside of the LED component and is fixedly connected to the base. The protective cover includes an inner cover and a waterproof film. The inner cover is fixedly connected to the top of the base and is provided with heat dissipation holes, and the waterproof film is fixedly connected to the outside of the inner cover.
[0007] By adopting the above technical solution, it can play a role in moisture-proofing while also helping the LED light board dissipate heat, thereby extending the service life of the LED light board.
[0008] Further, the inner cover is made of a hard transparent material.
[0009] Further, the waterproof film is a breathable waterproof film.
[0010] Further, a support frame is detachably connected to the outside of the inner cover. A cavity is provided between the support frame and the inner cover, and the waterproof film is disposed closely against the support frame.
[0011] By adopting the above technical solution, the cavity can serve as a buffer space to reduce the direct impact of external environmental temperature changes on the LED component, and contribute to stabilizing the microenvironment inside the lamp board.
[0012] Further, a clamping groove is provided on the side surface of the inner cover. The support frame is made of an elastic material and is clamped in the clamping groove.
[0013] Further, a sealing strip is provided in the clamping groove.
[0014] Further, the support frame is made of a transparent material, and the support frame is provided with a frosted surface.
[0015] Further, the waterproof film is made of polyurethane material.
[0016] In summary, the beneficial effects of the present utility model are as follows:
[0017] The inner cover of the present application is made of a hard transparent material, which ensures the strength of the protective cover. At the same time, heat dissipation holes are provided, which helps heat dissipation. Meanwhile, combined with the waterproof film outside the inner cover, while preventing moisture and water from invading the LED lamp board, the heat dissipation effect of the LED lamp board is improved, and the service life of the LED lamp board is prolonged;
[0018] A support frame is detachably connected to the outside of the inner cover. The cavity between the support frame and the inner cover serves as a buffer space, which helps to reduce the influence of external environmental temperature changes on the LED component and also helps with heat dissipation;
[0019] The support frame is made of a transparent material and is provided with a frosted surface, which further softens the light, prevents the support frame from obstructing the illumination of the lamp board, and can provide support for the waterproof film at the same time, making the lamp board more beautiful.
