Background technique

Explosion-proof lamp refers to for hazardous area existing for imflammable gas and dust, can prevent issuable electricity inside lamp Arc, spark and high temperature ignite imflammable gas and dust in ambient enviroment, to reach the lamps and lanterns of requirement of explosion proof.

But existing dust chamber's explosion-proof lamp, it is internal to be provided with rectifier mostly, and rectifier is easy when being powered Heat is generated, to easily rectifier be made to cause in a humidity environment because of fever the phenomenon that damaging, while existing anti- Quick-fried lamp can generate amount of heat at work, and heat is to carry out heat transfer by aluminum alloy casing surface to radiate mostly, This radiating mode tends not to adequately be radiated the heat inside explosion-proof lamp, to cause lamp life lower.

Utility model content

The purpose of this utility model is to provide a kind of dust chamber's explosion-proof lamps, mentioned above in the background art whole to solve Stream device easily causes damage in the environment of making moist fever, radiates insufficient the problem of causing explosion-proof lamp service life reduction.

To achieve the above object, the utility model provides the following technical solutions: a kind of dust chamber's explosion-proof lamp, including lampshade, Lamp stand is connected at the top of the lampshade, and the outer surface of the lampshade is provided with light transmission net, the top of the lamp stand connects respectively It is connected to suspender member and lamp chamber, running through below the outer surface of the suspender member has rotation bolt, and the inner upper of the suspender member Through there is standing screw, wire connection cavity is connected at the top of the lamp chamber, and two upper sides of the lamp chamber run through heat release hole, The heat release hole is internally connected with multiple strainers, the top of wire connection cavity terminal plate there are two, and the wire connection cavity Be internally connected with and connect electric block, the bottom for connecing electric block is connected with capacitor, and the bottom of the capacitor passes through lead wire lever and connects It is connected to diode, the bottom of the diode is connected with multiple lamp beads.

Preferably, multiple lamp beads are in " semicircle ", and multiple lamp beads are arranged in lamp stand in " circular array column-shaped " Bottom.

Preferably, multiple strainers are arranged in parallel in the inside of heat release hole.

Preferably, helical ring is wound with a plurality of screw thread above the outer surface of the wire connection cavity.

Preferably, the lampshade is formed using tempered glass.

Preferably, the suspender member is in " arch ", and the suspender member is made using stainless steel material.

Preferably, second shaft through turntable top and extend to the inside of turntable.

Compared with prior art, the utility model has the beneficial effects that this kind of dust chamber's explosion-proof lamp, be provided with diode, Lamp bead and capacitor, capacitor can come when electric current passes through by the capacitive reactance generated under the AC signal frequency of alternating current Maximum operating currenbt is limited, decompression drop stream process is carried out to circuit to realize, makes diode can also be in ordinary incandescent lamp with this Lamp holder on work, thus so that diode is converted visible light for the electric energy of alternating current, and illuminate by lamp bead, and diode It is also more energy saving in illumination for LED light source, while it being additionally provided with heat release hole and strainer, in explosion-proof lamp work, heat release hole can The amount of heat that generates adequately is distributed when to explosion-proof lamp work, and the strainer of multiple settings successively subtracts because of itself hole It is small, and then the dust in dust chamber can be filtered, so that dust be avoided to enter in explosion-proof lamp by the heat release hole of explosion-proof lamp Portion, with this avoid explosion-proof lamp at work because heat distributes it is insufficient due to cause explosion-proof lamp service life to shorten.
