Description

Technical Field

[0001] The utility model relates to the field of lighting, in particular to an integrated explosion-proof LED floodlight. Background Art

[0002] Explosion-proof lamps are often used to provide lighting in places where flammable gases or dust are present to prevent the arc and high temperature generated by the lamps from igniting the gas and dust in the environment. Therefore, the sealing ability and heat dissipation ability of the lamps are important factors affecting the safety performance of explosion-proof lamps.

[0003] To improve the heat dissipation capacity, the lamp housing is provided with exposed heat sinks. The enclosed area formed by these heat sinks and the edge of the lamp cover is prone to water and dust accumulation. Especially when the lamp is fixed in a humid environment, long-term water accumulation on the lamp can easily cause the accumulated water to rust, destroying the sealing of the lamp and increasing the risk of leakage. Utility Model Content

[0036] See also Figure 1 and Figure 2 The utility model provides an integrated explosion-proof LED floodlight 10, which includes: a lamp housing 100, a lens 200, a lamp board 300, a control board 400, a wiring socket 500 and two covers 600.

[0037] See also Figure 3 、 Figure 4 and Figure 7 The lamp housing 100 includes an integrally formed light-emitting portion 110, a receiving portion 120, and a plurality of heat sinks 130. The heat sinks 130 extend from the outer wall of the light-emitting portion 110 to the outer wall of the receiving portion 120. The receiving portion 120 is provided with an inclined surface 121 for guiding the accumulated water to flow away from the light-emitting portion 110.

[0038] See also Figure 3 and Figure 4 The light projection portion 110 is provided with a light source cavity 111, and the lens 200 and the light board 300 are provided in the light source cavity 111;

[0039] See also Figure 2 and Figure 4 The receiving portion 120 is provided with a wiring cavity 122 and an electrical cavity 123, the control board 400 is provided in the electrical cavity 123, the wiring seat 500 is located in the wiring cavity 122, and two covers 600 are provided on the receiving portion 120 for sealing the wiring cavity 122 and the electrical cavity 123;

[0040] See also Figure 5 、 Figure 6 and Figure 7 The cover 600 is provided with a flange 610 and an extension portion 620. The extension portion 620 is inserted into the wiring cavity 122 or the electrical cavity 123. The flange 610 is in contact with the receiving portion 120, and a sealing ring 630 is provided at the position where the flange 610 contacts the receiving portion 120. The flange 610 is provided with a conduit groove 611 and a drainage hole 612.

[0041] The difference in thickness at the boundary between the light-emitting portion 110 and the receiving portion 120 makes it prone to water accumulation. This is especially true when the cover 600 is installed. The light-emitting portion 110, the receiving portion 120, and the cover 600 form a concave area with higher sides and a lower center, making it difficult to drain accumulated water. To address this issue, an inclined surface 121 is provided on the outer wall of the receiving portion 120 to guide accumulated water toward the location of the cover 600, into the confluence groove 611, and out through the drainage hole 612.

[0042] It should be noted that the projecting part 110, the receiving part 120 and the heat sink 130 are an integrally formed structure, and the projecting part 110 and the receiving part 120 are respectively provided with a light source cavity 111, a wiring cavity 122 and an electrical cavity 123, that is, the lamp housing 100 is provided with a light source cavity 111, a wiring cavity 122 and an electrical cavity 123, and the two main heat sources of the lamp board 300 and the control board 400 and the wiring socket 500 are separated by three chambers. On the one hand, it avoids heat concentration and affects the heat dissipation efficiency when the floodlight is running; on the other hand, it allows the components in the floodlight to be assembled in the lamp housing 100, making the floodlight structure more compact.

[0043] The above-mentioned integrated explosion-proof LED floodlight 10 has the following advantages:

[0044] 1. The projecting portion 110, the housing portion 120, and the heat sink 130 are integrally formed, thereby housing the lamp panel 300, the lens 200, the control board 400, the wiring socket 500, and the lamp components on the lamp housing 100. The light source cavity 111, the wiring cavity 122, and the electrical cavity 123 are used to separate the heat source to avoid heat concentration, making the projector structure compact while maintaining the heat dissipation effect.

[0045] 2. The inclined surface 121 on the receiving portion 120 guides the accumulated water to flow toward the cover 600, so that the accumulated water enters the confluence groove 611 and flows out from the drainage hole 612. A sealing ring 630 is provided to prevent external moisture from entering the interior of the lamp, thereby improving the safety performance of the floodlight.

[0046] 3. An extension portion 620 is provided on the cover 600 to be inserted into the wiring cavity 122 and the electrical cavity 123, thereby extending the contact area between the cover 600 and the cavity wall, thereby increasing the difficulty of external moisture and dust entering the interior of the floodlight, further improving the sealing of the floodlight, and thus improving the safety performance of the floodlight.

[0047] See also Figure 2 In one embodiment, the integrated explosion-proof LED floodlight 10 further includes a front frame 710, which is connected to the projection unit 110 and is used to secure the lens 200. The integrated explosion-proof LED floodlight 10 further includes a mesh cover 720, which is disposed on the front frame 710. The mesh cover 720 and the front frame 710 cooperate to provide protection for the lens 200, preventing foreign objects from directly impacting the lens 200.

[0048] See also Figure 4 In one embodiment, the housing portion 120 is provided with a wiring conduit 124, which is in communication with the wiring cavity 122. Preferably, a nameplate is provided on the cover 600. The information on the nameplate allows the user to understand the wiring status of the housing portion 120, facilitating subsequent maintenance and repair.

[0049] See also Figure 4 Preferably, a guide tube 800 is provided between the light source cavity 111 and the electrical cavity 123 and between the electrical cavity 123 and the wiring cavity 122. This facilitates the arrangement of wires when wiring the light board 300, the control board 400 and the wiring seat 500, simplifies wiring operations, and facilitates maintenance.

[0050] See also Figure 3 Preferably, the control board 400 is connected to the cover 600, and a gap is provided between the control board 400 and the inner wall of the electrical cavity 123. The lamp board 300 is the main heat generating part. Separating the cover 600 from the control board 400 and the inner wall of the electrical cavity 123 prevents heat generated by the lamp board 300 from interfering with the control board 400 and thus preventing heat from interfering with the normal operation of key components.

[0051] See also Figure 1 and Figure 2 In one embodiment, the integrated explosion-proof LED floodlight 10 further includes a tripod 730, which is rotatably mounted on the lamp housing 100. The tripod 730 is used to secure the floodlight to a target location, and the tripod 730 is rotatably connected to the lamp housing 100, allowing for flexible adjustment of the floodlight's lighting direction.

[0052] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
