LED explosion-proof lamp

Abstract

The invention relates to a novel LED explosion-proof lamp, which mainly comprises a lamp shell, an LED light source module integrated and packed by multiple chips, and an LED heat dissipation device, wherein the lamp shell is used for accommodating the LED light source module and the LED heat dissipation device and consists of a lampshade, a lamp body and a bottom cover; the lampshade is arranged on one side of the lamp body, and the other side of the lamp body is provided with the bottom cover; one side of the lamp body is open, and a conical shell with an accommodating space is arranged in the closed other side of the lamp body; the LED heat dissipation device consists of a plurality of heat conducting pipes and a metal substrate; one end of each heat conducting pipe is inserted into a cylindrical insertion hole on the inner wall of the lamp body, and the other side of the heat conducting pipe is inserted into a circular insertion hole of the lamp body and tightly matched by means of an embedded seat; the LED light source module consists of a plurality of LED chips which are connected in series and parallel and fixed on a high heat conducting substrate, the electrified LED chips uniformly excite a phosphor layer, gaps between the chips and the phosphor are filled by using silica gel or air or inert gas, and the formed white light is shaped and distributed by a lens to form a uniform luminous surface; and the heat emitted by the LED light source module is transferred to three different parts on the lamp body through the heat conducting pipes and the metal substrate respectively, so the heat dissipation effect is good.

Description

technical field [0001] The invention relates to an explosion-proof LED lamp, in particular to an explosion-proof lamp design in which an integrated and packaged LED light source module is combined with a heat-conducting pipe to quickly conduct heat and the lamp body dissipates heat. Background technique [0002] With its energy saving, environmental protection, safety and reliability, LED light sources have gradually replaced the incandescent lamps used in traditional explosion-proof lamps and entered practical applications. However, there are the following problems in practical applications: [0003] 1. The LED explosion-proof lamp on the market uses a single packaged LED lamp bead, and multiple lamp beads are arranged to form an explosion-proof lamp. The luminous intensity is weak, the irradiation distance is short, and there is a greater risk of damage to multiple lamp beads, and the safety and reliability are poor. [0004] 2. General LED explosion-proof lights, in orde...

AI Technical Summary

Problems solved by technology

[0003] 1. The LED explosion-proof lamps on the market use a single packaged LED lamp bead, and multiple lamps are arranged to form an explosion-proof lamp. The luminous intensity is weak, the irradiation distance is short, and there is a greater risk of damage to multiple lamp beads, and the safety and reliability are poor.

[0004] 2. In general LED explosion-proof lamps, in order to meet the requirements of explosion-proof, the LED light source is sealed in the lamp body, the heat dissipation effect is poor, the light decay is large, and the service life is short. Heat dissipation method, but it is difficult to prepare a high-precision heat pipe as shown in the patent and closely match the lamp body
