Description

Technical Field

[0001] This utility model relates to a lighting lamp, particularly an explosion-proof lamp suitable for use as work lighting, scene lighting, and floodlighting in hazardous areas such as various offshore platforms, chemical and natural gas tankers, hazardous material terminals, and oil platforms. It is suitable for use in environments containing Class IIA, IIB, and IIC explosive gases, and in hazardous areas such as Zone 1 and Zone 2. Background Art

[0002] Existing explosion-proof lamps have the following shortcomings: 1. The market lacks compact, low-power explosion-proof platform lamps; 2. The small size of the lamps makes heat dissipation difficult to achieve, shortening their service life; 3. In terms of explosion-proof performance, the light source and driver components are typically housed in a single cavity, resulting in a large net volume and pressure overlap. This results in the lamp withstanding greater explosion pressure under the same conditions, compromising its explosion-proof performance. Therefore, it is necessary to design an explosion-proof lamp that meets market demand and addresses this gap in the market. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an explosion-proof lamp, which can reduce the net volume inside the lamp, reduce heat accumulation of the light source and power supply, and increase the service life of the driving power supply and the light source.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is to provide an explosion-proof lamp, including a shell, a front cover and a wiring cover, wherein the front cover and the glass lampshade are sealed by an O-ring, wherein the front cover and the shell are sealed by a threaded joint surface to form a light source cavity, and the shell and the wiring cover are sealed by a cylindrical joint surface to form a power supply cavity; the light source cavity and the power supply cavity are separated from each other.

[0005] In the above-mentioned explosion-proof lamp, heat dissipation ribs are provided on the outer sides of the shell and the wiring cover.

[0006] In the above-mentioned explosion-proof lamp, the glass lampshade is fit into the inner side of the front cover, is sealed with glue and is fixed with a threaded pressing ring.

[0007] In the above-mentioned explosion-proof lamp, the contact surface between the side surface of the glass lampshade and the front cover is an epoxy adhesive bonding surface.

[0008] The above-mentioned explosion-proof lamp, wherein the wiring cover is provided with a ceiling plate.

[0009] The above-mentioned explosion-proof lamp, wherein a handle is installed on the shell.

[0010] Compared with the prior art, the present invention has the following beneficial effects: the explosion-proof lamp provided by the present invention adopts a combined design of a light source cavity and a power supply cavity, which reduces the net volume and heat accumulation inside the lamp and increases the service life of the driving power supply and the light source.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Figure 1 This is a schematic diagram of the structure of the explosion-proof lamp of the utility model; Figure 2 This is a schematic diagram of the cross-sectional structure of the explosion-proof lamp of the utility model.

[0023] See Figure 1 and Figure 2 The explosion-proof lamp provided by the utility model includes a shell 1, a front cover 2 and a wiring cover 3. The front cover 2 and the glass lampshade 8 are sealed with an O-ring, wherein the front cover 2 and the shell 1 are sealed with a threaded joint surface 6 to form a light source cavity 5, and the shell 1 and the wiring cover 3 are sealed with a cylindrical joint surface 7 to form a power supply cavity 4; the light source cavity 5 and the power supply cavity 4 are separated from each other.

[0024] The explosion-proof lamp provided by this utility model utilizes a combined light source cavity 5 and power supply cavity 4, reducing the net internal volume of the lamp, the lamp's external structure, and material costs. Heat dissipation ribs 12 are provided on the outer surfaces of the housing 1 and the wiring cover 3, increasing the lamp's heat dissipation area, reducing heat accumulation in the light source and power supply, and extending the service life of the driver power supply and light source.
