Abstract

The utility model relates to an explosion-proof lamp. The explosion-proof lamp is provided with a fixing base, an upper shell, a middle shell and a lower shell, wherein the fixing base, the upper shell, the middle shell and the lower shell are fixedly connected from top to bottom in sequence. A wiring cavity is formed in the upper shell, a high frequency generator is arranged in the wiring cavity, a lamp holder is arranged in the middle shell, a light source is connected to the lamp holder, the light source is covered with a tempered glass cover, and a protective net is arranged on the outer portion of the tempered glass cover. The explosion-proof lamp further comprises at least one dust sensor which is fixedly arranged on the outer wall of the middle shell. According to the explosion-proof lamp, at least one dust sensor is additionally arranged on the explosion-proof lamp, the dust sensor is fixedly arranged on the outer wall of the middle shell, and therefore the dust sensor can be used for detecting dust quantity in current environment; when the dust quantity is close to the critical point, an alarm apparatus gives an alarm, and therefore life safety of workers who work in the current environment or nearby residents are ensured.

Description

A kind of explosion-proof lamp

Technical field

The utility model relates to the lighting device technical field, particularly a kind of explosion-proof lamp.

Background technology

At present, electric light source commonly used has incandescent lamp, LED lamp, fluorescent lamp, high-pressure mercury lamp, Metal halogen lamp etc., occasion at dangerous property gas, such as mine inside, for preventing that electric spark from igniting and heat accumulation, light fixture there is strict requirement of explosion proof, and the electric light source light fixture of commonly using at present, incandescent lamp can give out a large amount of heats when using, having electric spark during fluorescent lamp starting produces, other light fixtures or expensive, or structure installs difficulty, this just so that the light fixture of explosion-proof occasion select to be very restricted.

The utility model content

The purpose of this utility model is to overcome the defective that prior art exists, and a kind of explosion-proof lamp of simple in structure, good heat dissipation effect is provided.

The technical scheme that realizes the utility model purpose is: a kind of explosion-proof lamp has the holder, upper casing, mesochite and the lower casing that are fixedly connected sequentially from top to bottom; Has wire connection cavity in the described upper casing; Be provided with radio-frequency generator in the described wire connection cavity; Be provided with lamp socket in the described mesochite; Be connected with light source on the described lamp socket; Safety glass cover of described light source upper cover; The outside of described safety glass cover is provided with catch net; Also has dust sensor; Described dust sensor has one at least, and dust sensor is fixedly installed on the outer wall of mesochite.

Annular array has radiating ribs on the outer wall of the described upper casing of technique scheme.

The described lower casing of technique scheme is inverted bowl-shape.

The projection that has equidistant distribution on the inwall of the described lower casing of technique scheme.

The described holder of technique scheme is provided with at least three and connects otic placode; Described respectively the connection is equipped with installing hole on the otic placode.

The junction of the described dust sensor of technique scheme and mesochite is provided with sealing ring.

After adopting technique scheme, the utlity model has following positive effect:

(1) the utility model increases dust sensor; And dust sensor has one at least, and dust sensor is fixedly installed on the outer wall of mesochite; Can detect dust number in the current environment by dust sensor, when dust number during near critical point, alarm equipment alarm so that the worker who in current environment, works or near resident's life be protected safely.

(2) annular array has radiating ribs on the outer wall of upper casing of the present utility model; Can play well thermolysis, prolong the service life of light fixture.

(3) have the projection of equidistant distribution on the inwall of lower casing of the present utility model, can make the reflecting effect of light better.

(4) holder of the present utility model is provided with at least three connection otic placodes; Be equipped with installing hole on each otic placode; Make whole lamp installation convenient, quick.
