According to the explosion-proof lamp of the above embodiment, since the lamp cap assembly 10 and the driving assembly 20 are accommodated in the sealed housing 30, the housing 30 is provided with the wiring hole 320, and the wiring hole 320 is also provided with the plug, the housing 30 can be sealed while the driver 220 is electrically connected, so that the housing 30 is insulated from any possibility of causing sparks. The bracket 40 is hinged to both sides of the housing 30 and provided with a handle 410, and the handle 410 is provided with a mounting hole 420 for mounting and fixing the explosion-proof lamp. After the bracket 40 is fixedly installed by a worker, the illumination angle can be changed only by adjusting the hinge angle of the bracket 40 and the housing 30. The anti-explosion lamp is not required to be disassembled and assembled again by staff, so that the problem that the illumination angle of the anti-explosion lamp is difficult to adjust after the anti-explosion lamp is installed can be solved.

It should be noted that, in actual use, the bracket 40 does not have to be fixed through the mounting hole 420, and the bracket 40 itself can support the explosion-proof lamp to stand on the ground or the table top. The illumination angle of the explosion-proof lamp is adjusted to a desired state by adjusting the hinge angle of the bracket 40 with the housing 30.

Generally, the housing 30 is formed by two opposite pieces, and the two pieces are fixed by screws. In order to ensure the tightness of the housing 30, the connection and the screw fixing are usually provided with waterproof washers.

Since the explosion-proof lamp is often collided with by a hard object due to the use situation of the explosion-proof lamp, a number of reinforcing structures are provided on the housing 30.

Specifically, reinforcing ribs, reinforcing columns, etc. may be employed to strengthen the housing 30. The tempered glass 310 has strong strength, and even if a splashed stone is present in the field or the explosion-proof lamp falls from a high place, the tempered glass 310 is not broken, and the lamp head assembly 10 and the driving assembly 20 inside the housing 30 are prevented from being exposed to the environment to cause a fire or explosion accident.

In certain embodiments, the lamp head assembly 10 further includes a lens 130, the lens 130 being capable of adjusting the light emission angle of a light source (not shown).

The lens 130 is an optical element made of transparent material, the surface of which is a part of a sphere, and includes both a plastic lens and a glass lens, and the glass lens is more expensive than the plastic lens. The lens 130 is a common component in the field of lamps, and is mainly used for adjusting the illumination angle to collect light and send the light out according to a designed direction.

In some specific embodiments, the light source (not shown) is a lamp panel 140 with LED lamps 1410 arranged in an array, and the lens 130 is disposed corresponding to the LED lamps 1410.

The LED lamp 1410 is an electroluminescent semiconductor material chip (i.e. the lamp panel 140), and is cured on the bracket by silver or white glue, then the chip and the circuit board are connected by silver or gold wires, the periphery is sealed by epoxy resin, the function of protecting the internal core wire is achieved, and finally the housing is installed, so the anti-seismic performance of the LED lamp is good. Each LED lamp 1410 corresponds to one lens 130, ensuring that the light of the LED lamp 1410 irradiates the housing 30.

In some embodiments, referring to fig. 2, the driving assembly 20 includes a connection terminal 240, and the connection terminal 240 is disposed at an edge of the heat sink 230 and is used for threading wires.

The heat sink 230 is generally disposed between the lamp panel 140 and the driver 220, and the lamp panel 140 and the driver 220 are main heat sources, so heat dissipation from the heat sink 230 is required. The heat sink 230 is generally abutted against the housing 30, and the housing 30 is preferably made of metal, so that heat of the heat sink 230 can be conducted conveniently.

The driver 220 needs to supply power to the lamp panel 140, so that the connection terminal 240 needs to be disposed at the edge of the heat sink 230. The lamp panel 140 and the driver 220 are electrically connected through the connection terminal 240 by a wire (not shown).

In some specific embodiments, heat sink 230 includes heat sink fins. The heat dissipation effect of the heat dissipation fins is better, and the contact area between the heat dissipation body 230 and the air can be increased.

In certain embodiments, the housing 30 further includes a tab 340, the tab 340 being disposed between the tempered glass 310 and the lens 130 for preventing the tempered glass 310 from directly contacting the lens 130.

The pressing piece 340 can fasten both the lamp head assembly 10 and the driving assembly 20 and prevent the tempered glass 310 from crushing the lens 130.

In general, the pressing sheet 340 is a flexible member such as rubber or plastic, or a plurality of pressing sheets may be provided so as to flatten the pressure of the transparent plate.

In some embodiments, the damping structure 50 is further included, and the damping structure 50 is disposed at the connection between the bracket 40 and the housing 30.

The damping structure 50 refers to a structure in which a damping material is integrated with a member to consume the amount of vibration. The damping structure is a structure that integrates damping material with the member to dissipate vibration energy. The basic form is as follows: (1) The free damping layer structure, i.e. a layer of damping material is directly deposited on the base plate of the component. The loss factor is related to the thickness ratio of the damping layer and the base layer plate and the elastic modulus ratio thereof, and the thickness of the damping layer is preferably 1 to 4 times that of the base layer plate.

The damping structure 50 can prevent the support 40 from rotating with the housing 30 at any time, thereby affecting illumination. After the user rotates the bracket 40 and the housing 30 by a certain angle, the bracket 40 and the housing 30 remain relatively fixed unless a large force is applied.

In some specific embodiments, referring to fig. 2 and 3, the damping structure 50 includes a first annular raised grain 510 and a second annular raised grain 520 corresponding to the first annular raised grain 510, the first annular raised grain 510 is fixedly disposed on the support 40, the second annular raised grain 520 is fixedly disposed on the housing 30, and the first annular raised grain 510 and the second annular raised grain 520 can rotate relatively.

In certain embodiments, the damping structure 50 includes a first connection ring 530 including a first annular corrugation 510 and a second connection ring 540 including a second annular corrugation 520, the first annular corrugation 510 corresponding to the second annular corrugation 520, the first connection ring 530 fixedly coupled to the support 40, and the second connection ring 540 fixedly coupled to the housing 30.

In this embodiment, the first annular raised grain 510 and the second annular raised grain 520 are not directly disposed on the bracket 40 and the housing 30, but are disposed on the first connecting ring 530 and the second connecting ring 540, respectively. This facilitates assembly during production and also facilitates maintenance and replacement of the connection between the bracket 40 and the housing 30.

In some specific embodiments, referring to fig. 3, the damping structure 50 further includes an elastic member 550, where the elastic member 550 is disposed between the first connection ring and the bracket, or between the second connection ring and the housing.

The elastic member 550 can provide a certain movement space for the first and second

annular corrugations

510 and 520, so as to facilitate the switching between the engaged and disengaged state of the first and second connection rings 530 and 540.
