Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an explosion-proof LED lamp. Background Art

[0002] The LED lamp is an electroluminescent semiconductor material chip, which is cured to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire. It is sealed with epoxy resin on all sides to protect the internal core wire, and finally the outer shell is installed, so the LED lamp has good earthquake resistance.

[0003] When used in practice, LED lamps contain light-emitting diodes (LEDs), which have filaments for emitting light. When a high current is encountered during use, the filaments will melt. Once the filaments melt, it is easy to cause the internal pressure of the lamp to increase, causing the lamp to break. Once the molten material of the filament meets the explosive gas, dust or a mixture thereof at the production or rescue site, it will cause an explosion. Utility Model Content

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0014] 1. In the utility model, a buffer cavity is provided inside the docking seat, and the inner bottom surface of the buffer cavity and the LED lamp cover are connected to each other through a through hole, so that at the moment when the high voltage is generated after the filament inside the LED lamp cover is melted, the high voltage can flow to the inside of the buffer cavity through the through hole, and finally be discharged to the outside from the guide hole inside the buffer cavity, so as to prevent the high voltage from damaging and breaking the LED lamp cover.

DETAILED DESCRIPTION

[0024] The utility model will now be further described in detail with reference to the accompanying drawings.

[0025] Embodiment 1, as Figure 1-3 As shown, the utility model provides a technical solution for explosion-proof LED lamps: comprising an insulating sleeve 1, an LED lamp cover 3 is fixed between the inner walls of the insulating sleeve 1 at the bottom edge, the interior of the LED lamp cover 3 is in a vacuum state, a docking seat 4 is fixed between the inner walls of the insulating sleeve 1 at the middle position, a buffer cavity 9 is provided inside the docking seat 4, the inner bottom surface of the buffer cavity 9 is conical, a through hole 14 is provided on the inner bottom surface of the buffer cavity 9 that penetrates into the interior of the LED lamp cover 3, and a sealing block 12 is arranged inside the buffer cavity 9.

[0026] The effect achieved by the entire embodiment 1 is that a buffer cavity 9 is opened inside the docking seat 4, and at the same time, the inner bottom surface of the buffer cavity 9 and the LED lamp cover 3 are connected to each other through the through hole 14, so that at the moment when high voltage is generated after the filament 8 inside the LED lamp cover 3 melts, the high voltage can flow to the inside of the buffer cavity 9 through the through hole 14, and finally be discharged to the outside from the guide hole 6 inside the buffer cavity 9, thereby preventing the high voltage from damaging and breaking the LED lamp cover 3.

[0027] Embodiment 2, as Figure 1-3 As shown, the bottom of the sealing block 12 fits with the inner bottom surface of the buffer cavity 9, a spring 11 is fixed to the inner top surface of the buffer cavity 9, the bottom of the spring 11 is fixed to the top of the sealing block 12, and the inner walls on both sides of the buffer cavity 9 are provided with limiting grooves 10, and the two sides of the sealing block 12 are fixed with guide blocks 13 slidably connected to the inside of the limiting grooves 10, and the bottom of the buffer cavity 9 is provided with a plurality of guide holes 6 equidistantly along the circumferential direction, and one end of the plurality of guide holes 6 penetrates to the outside of the docking seat 4, and the outer surface of the insulating sleeve 1 is provided with a plurality of side openings 2 equidistantly along the circumferential direction, and the top of the docking seat 4 is provided with copper contacts 5 near the edges on both sides, and the inner walls on both sides of the LED lamp cover 3 are fixed with copper connecting rods 7, and a filament 8 is provided between the opposite sides of the two copper connecting rods 7.

[0028] The effect achieved by the entire embodiment 2 is that when high pressure is generated, the high-pressure airflow enters the interior of the through hole 14, and the pressure acts on the bottom of the sealing block 12. When the upward thrust on the sealing block 12 is greater than the downward elastic pressure of the spring 11 on the sealing block 12, the sealing block 12 slides upward. At this time, the bottom surface of the sealing block 12 and the bottom surface of the buffer cavity 9 are separated from each other. After the airflow enters the buffer cavity 9, it is discharged to the outside through the guide hole 6. During installation, the LED lamp cover 3 can be fixedly installed by connecting it with the external docking point through the insulating sleeve 1. Two copper connecting rods 7 are set on the inner wall of the LED lamp cover 3 to facilitate fixing the filament 8 thereon, so that the filament 8 is suspended in the air, which helps the filament 8 to emit light.

[0029] Working principle: a buffer cavity 9 is provided inside the docking seat 4, and the inner bottom surface of the buffer cavity 9 is connected to the LED lamp cover 3 through the through hole 14. Thus, when the filament 8 inside the LED lamp cover 3 is melted and high pressure is generated, the high pressure can flow to the inside of the buffer cavity 9 through the through hole 14, and finally be discharged to the outside from the guide hole 6 inside the buffer cavity 9 to prevent the high pressure from damaging and breaking the LED lamp cover 3. When high pressure is generated, the high pressure airflow enters the inside of the through hole 14, and the pressure acts on the bottom of the sealing block 12. When the upward thrust of the sealing block 12 is greater than the downward elastic pressure of the spring 11 on the sealing block 12, the sealing block 12 slides upward. At this time, the bottom surface of the sealing block 12 is separated from the inner bottom surface of the buffer cavity 9. After the airflow enters the buffer cavity 9, it is discharged to the outside through the guide hole 6. During installation, the LED lamp cover 3 can be fixedly installed by connecting it with the external docking point through the insulating sleeve 1. Two copper connecting rods 7 are provided on the inner wall of the LED lamp cover 3 to facilitate fixing the filament 8 thereon, so that the filament 8 is suspended, which helps the filament 8 to emit light.
