The implementation of an explosion-proof lamp according to the present invention is described in detail below with reference to fig. 1 to 9.

It should be noted that the explosion-proof lamp 10 can be used for illumination or other purposes in a tunnel, and of course, can also be used in other suitable places.

As shown in fig. 1 to 3 and 5, the explosion-proof lamp 10 includes a lamp body 100, a top cover 200, a light-transmitting surface cover 300, a driving assembly 400 and a light source assembly 500, wherein the lamp body 100 includes a main housing 110 and a connecting body 120. As shown in fig. 5, 8 or 9, in order to facilitate installation of the driving assembly 400 and improve the explosion-proof performance of the driving assembly 400, a sealed electrical cavity 130 is defined between the main housing 110 and the top cover 200.

It should be noted that in the present embodiment, as shown in fig. 2 and 5, the driving assembly 400 is mounted on the main housing 110 in the electrical cavity 130 for easy installation and maintenance. In addition, to make the structure of the explosion-proof lamp 10 simpler and more compact, the electrical cavity 130 is mainly formed by a cavity opened in the main housing 110, and correspondingly, the driving assembly 400 is completely accommodated in the cavity.

To achieve the electrical driving of the explosion-proof lamp 10, as shown in fig. 8, the main housing 110 is provided with a mounting hole 112, and a cable assembly 160 is hermetically inserted into the mounting hole 112, wherein the driving assembly 400 may include a connecting terminal 410 and a non-emergency driving unit 420, the non-emergency driving unit 420 is electrically connected to the connecting terminal 410, and a cable passes through the cable assembly 160 to enter the electrical cavity 130 from the mounting hole 112 to be electrically connected to the connecting terminal 410. Of course, in another case, the driving assembly 400 may include the connection terminal 410, the emergency driving unit 430, and the storage power source 440, wherein the emergency driving unit 430 is electrically connected to the connection terminal 410 and the storage power source 440. When emergency lighting is required, the emergency driving unit 430 is supplied with power from the storage power source 440, and normally, supplied with power from the current supplied from the cable connected to the connection terminal 410.

It should be noted that, as shown in fig. 2 and 5, the top cover 200 is detachably mounted on the top end of the main housing 110 through a first fixing member 150 (e.g., a screw, etc.), and in order to accelerate the dissipation of heat in the electrical cavity 130, as shown in fig. 1 and 2, a plurality of heat dissipation ribs 111 are disposed on the outer wall of the main housing 110.

As shown in fig. 5, one end (generally, an upper end) of the connecting body 120 is integrally formed with the main housing 110, and a sealed light source cavity 140 is enclosed between the other end (generally, a lower end) of the connecting body 120 and the light-transmitting surface cover 300. As shown in fig. 5, the light source assembly 500 is mounted on the connecting body 120 in the light source cavity 140, and the light source assembly 500 is electrically connected to the driving assembly 400. Specifically, in the present embodiment, as shown in fig. 5, the light source assembly 500 is detachably mounted on the bottom end of the connector 120 through a third fixing member 520 (e.g., a screw).

It is understood that the electrical cavity 130 and the light source cavity 140 are independent of each other, in other words, the electrical cavity 130 is separated from the light source cavity 140 and both are distributed above and below each other in a common installation manner. Obviously, by adding the connecting body 120 to the lamp body 100 and integrally forming the connecting body 120 and the main housing 110, the integrity of the explosion-proof lamp 10 can be ensured, which is favorable for improving the heat dissipation performance and the explosion-proof performance of the explosion-proof lamp 10.

Specifically, in this embodiment, as shown in fig. 3 and 5, the transparent cover 300 can be detachably mounted on the bottom end of the connecting body 120 through a second fixing member 320 (e.g., a screw). Preferably, the transparent cover 300 is a transparent cover with a floodlight function, such as organic glass, which obviously enhances the light permeability, and also protects the circuit well, enhancing the waterproof, shockproof and explosion-proof performance of the explosion-proof lamp 10. In addition, in order to avoid the mutual influence of heat between the electrical cavity and the light source cavity 140, as shown in fig. 1 to 5, the connecting body 120 is a hollow structure, that is, a hollow design is adopted between the electrical cavity 130 and the light source cavity 140. Specifically, in the present embodiment, as shown in fig. 1 and 4, a plurality of heat dissipating through holes 121 are formed on an outer wall of the connecting body 120, wherein each heat dissipating through hole 121 is formed along a front-back direction of the connecting body 120. In order to improve the sealing performance of the light source cavity 140, the bottom wall of the connecting body 120 is not communicated with each heat dissipation through hole 121. Of course, in practice, the connecting body 120 may also have other suitable forms of hollow structures.

It can be understood that, because the electrical cavity 130 and the light source cavity 140 are integrally connected through the hollow-out connecting body 120, therefore, after the driving assembly 400 and the light source assembly 500 are respectively installed on the main housing 110 and the connecting body 120 of the lamp body 100, the mutual influence of heat between the electrical cavity 130 and the light source cavity 140 is favorably reduced, in other words, the heat dissipated by the driving assembly 400 in the electrical cavity 130 is not directly transferred to the light source cavity 140, correspondingly, the heat dissipated by the light source assembly 500 in the light source cavity 140 is not directly transferred to the electrical cavity 130, but is mostly directly dissipated through air, so that the heat dissipation area of the explosion-proof lamp 10 is increased.

Generally, this explosion-proof lamp 10 is the integral type, and the wholeness is strong, compares split type structure, and its heat dispersion also obtains the reinforcing, and correspondingly, the explosion-proof performance also obtains the reinforcing.

In one embodiment, in order to improve the explosion-proof performance of the explosion-proof lamp 10, such as preventing moisture from entering the electrical cavity 130, the explosion-proof lamp 10 further includes a first sealing assembly, and correspondingly, a first sealing groove 210 is formed on an inner wall of the top cover 200, wherein the first sealing assembly is installed in the first sealing groove 210, so that when the top cover 200 is covered on the main housing 110, the electrical cavity 130 can be sealed by the first sealing assembly under the fastening effect of the top cover 200. In the present embodiment, as shown in fig. 5, the first seal assembly includes a first seal ring 600, wherein the first seal ring 600 is fitted into the first seal groove 210, specifically, the shape of the first seal ring 600 is the same as the groove shape of the first seal groove 210, and the size of the first seal ring 600 is the same as or slightly larger than the size of the first seal groove 210.

In one embodiment, in order to improve the explosion-proof performance of the explosion-proof lamp 10, for example, prevent moisture from entering the light source cavity 140, the explosion-proof lamp 10 further includes a second sealing assembly, and correspondingly, a second sealing groove 310 is formed on the inner wall of the light-transmitting surface cover 300, wherein the second sealing assembly is installed in the second sealing groove 310, so that when the light-transmitting surface cover 300 covers the bottom end of the connector 120, the light source cavity 140 can be sealed by the second sealing assembly under the fastening action of the light-transmitting surface cover 300. In this embodiment, as shown in fig. 5, the second seal assembly includes a second seal ring 700, wherein the second seal ring 700 fits into the second seal groove 310. Specifically, the shape of the second seal ring 700 is the same as the groove shape of the second seal groove 310, and the size of the second seal ring 700 is the same as or slightly larger than that of the second seal groove 310.

In one embodiment, as shown in FIG. 5, light source assembly 500 includes a mounting plate 510 and a light-emitting source (not shown). The mounting plate 510 is mounted on the other end of the connecting body 120, and is specifically mounted on the lower end of the connecting body 120 through a third fixing member 520. The light source is mounted on the mounting plate 510 and electrically connected to the driving assembly 400, so that the lighting function of the explosion-proof lamp 10 is realized under the driving of the driving assembly 400.

Preferably, in order to improve the heat dissipation performance of the explosion-proof lamp 10 and thus the explosion-proof rating thereof, the mounting plate 510 is made of a metal material, and/or a heat dissipation layer is disposed between the mounting plate 510 and the connection body 120. Thus, good heat dissipation can be achieved through the mounting plate 510 and/or the heat dissipation layer, and electric sparks are prevented from being generated, and the mounting plate is shockproof and explosion-proof.

Preferably, the light emitting source is an LED light emitting source. Because the LED light source does not generate a large amount of heat during operation, it has an explosion-proof advantage, and can take away part of the heat generated during operation through the hollow connector 120, so that the temperature in the light source cavity 140 will hardly reach the ignition point of flammable and explosive gases, and thus the safety of the explosion-proof lamp 10 can be greatly improved.

By last can understand, generally, this explosion-proof lamp 10's simple structure is compact, and the wholeness is strong, and explosion-proof level is high, simple to operate, low cost, under the prerequisite that satisfies the heat dissipation requirement, novel structure, easy to assemble, dismantlement and maintenance, compare other integral type explosion-proof lamp 10 structures, this explosion-proof lamp 10 only need ensure that the installation site keeps unanimous can, the size of its lamp body etc. can adopt different models and size, so, can reduce the use quantity of mould widely to reduce the cost of mould.
