The explosion-proof lamp 10 generally includes three chambers, namely a light source chamber 202, a power supply chamber 102 and a wiring chamber 104. Wherein the light source cavity 202 is used to accommodate the light emitting panel 210 (i.e., the light source), the power supply cavity 102 is used to accommodate the backup power supply 140, and the wiring cavity 104 is used to connect external wires for supplying power to the light emitting panel 210. In the related art, the relative positions of the three chambers are not properly arranged, which results in a large volume of the explosion-proof lamp 10.

In view of the above, an embodiment of the present invention provides an explosion-proof lamp 10, which is reasonably and compactly arranged through relative positions of three cavities of the power supply cavity 102, the wiring cavity 104 and the light source cavity 202, and effectively reduces the volume of the lamp.

The overall construction, operation and technical effects of the explosion-proof lamp 10 will be described in detail.

Referring to fig. 1 and 2, the explosion-proof lamp 10 includes a base 100, a partition 200 and a lamp housing 300 connected in sequence, the base 100 is provided with a wiring cavity 104 and a power supply cavity 102, the partition 200 and the lamp housing 300 together enclose a light source cavity 202, an orthographic projection of the wiring cavity 104 on a first surface is at least partially overlapped with an orthographic projection of the light source cavity 202 on the first surface, an orthographic projection of the power supply cavity 102 on the first surface is at least partially overlapped with an orthographic projection of the light source cavity 202 on the first surface, an orthographic projection of the wiring cavity 104 and an orthographic projection of the power supply cavity 102 on a second surface are at least partially overlapped, the first surface is a plane perpendicular to a front-back direction of the explosion-proof lamp 10, and the second surface is a plane perpendicular to a.

That is, the power supply chamber 102 and the wiring chamber 104 are both at least partially opposed to the light source chamber 202 in the front-rear direction of the explosion-proof lamp 10, and the power supply chamber 102 and the wiring chamber 104 are both at least partially opposed to each other in the left-right direction or the up-down direction of the explosion-proof lamp 10. Arranging the relative positions of the three chambers such that the three chambers are at least partially opposed in some directions allows the three chambers to be arranged more compactly, thereby reducing the volume of the entire explosion-proof lamp 10 without changing the volume of the three chambers themselves.

It should be noted that the "front-back direction" in the present embodiment refers to the direction in which the light-emitting side (the side from which light is emitted) and the backlight side (the side away from the light-emitting side) of the explosion-proof lamp 10 are arranged, i.e., the ab direction in fig. 1; "left-right direction" refers to a direction perpendicular to the front-rear direction, i.e., the cd direction in fig. 1; the "up-down direction" refers to a direction perpendicular to both the front-back direction and the left-right direction, i.e., the ef direction in fig. 1.

In this embodiment, the power cavity 102 is disposed on a side of the base 100 facing the partition 200 such that the power cavity 102 is adjacent to the light source cavity 202, thereby facilitating electrical connection between the backup power source 140 in the power cavity 102 and the light emitting panel 210 in the light source cavity 202. The wiring cavity 104 is disposed on a side of the base 100 facing away from the partition 200 to facilitate external wires to be introduced into the wiring cavity 104 for wiring operation. Specifically, the power supply cavity 102 and the wiring cavity 104 are both disposed in the base body 110. In other embodiments, the power supply cavity 102 and the wiring cavity 104 can be disposed on the same side of the base 100, such as on a side of the base 100 facing the partition 200 or a side facing away from the partition 200.

In order to further improve the compactness of the arrangement of the power supply cavity 102 and the wiring cavity 104, in the present embodiment, the orthographic projection of the wiring cavity 104 on the first face completely coincides with the orthographic projection of the light source cavity 202 on the first face, the orthographic projection of the power supply cavity 102 on the first face completely coincides with the orthographic projection of the light source cavity 202 on the first face, and meanwhile, the orthographic projections of the wiring cavity 104 and the power supply cavity 102 on the second face completely coincide. The perfect coincidence of the projections can more effectively improve the compactness of the arrangement of the power supply cavity 102 and the wiring cavity 104.

In the present embodiment, the power supply cavity 102, the wiring cavity 104 and the light source cavity 202 are substantially rectangular parallelepiped. The rectangular parallelepiped structure can make the power supply cavity 102, the wiring cavity 104 and the light source cavity 202 more conveniently aligned, thereby further improving the compactness of the arrangement. In other embodiments, the projections of both the power supply cavity 102 and the wiring cavity 104 on the first face coincide with the projection of the light source cavity 202 on the first face, and the projections of the power supply cavity 102 and the wiring cavity 104 on the second face coincide.

In order to improve the explosion-proof performance of the wiring cavity 104, in the present embodiment, the wiring cavity 104 is an increased-safety explosion-proof structure, i.e., an e-type explosion-proof structure. In other embodiments, the wiring cavity 104 may also be an explosion-proof structure, i.e., a d-type explosion-proof structure. In order to isolate the wiring cavity 104 from the outside and improve safety, in this embodiment, the base 100 further includes a cover plate, which is connected to a side of the base 100 away from the partition 200 by screws and covers the opening of the wiring cavity 104.

The reinforcing blocks 130 are plural in number and are arranged at intervals along the edge 120. The reinforcing block 130 is integrally formed between the base 110 and the rim 120. The reinforcing block 130 can improve the structural strength of the entire base 100 on the one hand, and can leave a sufficient length space for the screw hole on the other hand, so as to improve the stability of the screw locking, thereby ensuring the structural stability of the entire explosion-proof lamp 10.

Next, the separator 200 will be described.

Referring to fig. 5, the partition board 200 has a substantially rectangular plate structure, and is provided with heat dissipation holes 204 for dissipating heat generated by the light emitting plate 210. In this embodiment, four heat dissipation holes 204 are all waist-shaped holes to improve heat dissipation performance. The light emitting plate 210 is substantially rectangular and is provided with LED lamp beads arranged in a rectangular array on one side thereof facing the lamp cover 300 away from the partition board 200. The light emitting plate 210 is located in the region between the four heat dissipation holes 204 to facilitate heat dissipation.

The lamp housing 300 is described below.

Referring to fig. 6, the lamp housing 300 may have different structures as long as the light source cavity 202 is formed by the light source 300 and the partition 200, and the light emitted from the light emitting plate 210 in the light source cavity 202 can pass through the lamp housing 300. In this embodiment, the lampshade 300 includes a frame 310 and a light-transmitting plate 320 connected to the frame 310, through holes for screws to pass through are formed at the edge of the frame 310, a light-transmitting opening is formed at the middle of the frame 310, and the light-transmitting plate 320 is substantially rectangular and shields the light-transmitting opening for light emitted by the light-emitting plate 210 to pass through.

The light source cavity 202 enclosed by the lampshade 300 and the partition board 200 adopts an explosion-proof structure, namely a d-type explosion-proof structure. In other embodiments, the light source cavity 202 may also be an explosion-proof structure with increased safety, i.e. an e-type structure, which is determined according to actual requirements.

The explosion-proof lamp 10 further includes a screw 330, and the screw 330 is locked to the base 100 after passing through the lamp cover 300 and the partition 200 in sequence. Specifically, the head of the screw 330 abuts against the outer wall of the lampshade 300, the stud of the screw 330 sequentially penetrates through the through hole on the lampshade 300 and the through hole on the partition board 200 and then retracts into the screw hole on the base 100 to connect the base 100, the partition board 200 and the lampshade 300, and the number of screws 330 is multiple, so as to ensure the structural stability of the explosion-proof lamp 10.

Finally, the working principle and process of the explosion-proof lamp 10 are described as follows:

the light panel 210 within the light source cavity 202 is normally powered by an external power source connected by wires from the wiring cavity 104. When the external power source is disconnected accidentally, the backup power source 140 in the power cavity 102 supplies power to the light emitting panel 210, thereby ensuring illumination in an accidental situation.
