Explosion-proof industrial LED lamp

Abstract

The invention discloses an explosion-proof industrial LED lamp. The explosion-proof industrial LED lamp comprises a lamp body, wherein a circuit board is fixedly connected to the interior of the lampbody, a liquid storage pipe is arranged inside the lamp body, a piston is movably arranged inside the liquid storage pipe, the liquid storage pipe is filled with an expansion liquid, a connecting rodis fixedly connected to the upper side wall of the piston, a heat dissipation block is fixedly connected to the upper end of the connecting rod, a through opening matched with the heat dissipation block in size is formed in the upper side wall of the lamp body, a plurality of heat dissipation flow channels are formed in the heat dissipation block, an extendable spring is fixedly connected betweenthe lower side wall of the heat dissipation block and the inner wall of the lamp body, and two openings are symmetrically formed in the outer wall of the lamp body. According to the explosion-proof industrial LED lamp, when the temperature in the lamp body is high, the heat dissipation block is pushed out to communicate with the outside, air convection heat dissipation is carried out through the heat dissipation flow channels, when the temperature of the lamp body rises continuously, top rods are triggered to move to enable rotating plates to rotate, the openings are opened, the convection area is increased, double insurance is achieved, the use safety of the lamp body is guaranteed, and lamp body damage and safety accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an explosion-proof industrial LED lamp. Background technique [0002] The LED lamp is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and the circuit board with silver or gold wires, and sealed with epoxy resin around it to protect the inner core wire. Function, finally install the shell, LED is a light-emitting diode, a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole occ...

Problems solved by technology

[0004] The current LED lamps mainly dissipate heat through their own heat sinks when dissipating heat, and the heat dissipation is poor. Long-term high temperature is likely to cause damage to the lamp body or even cause a safety accident. For example, the long-term convection between the lamp body and the external air will cause External impurities enter
