The LED particles are mounted on the LED particle mounting plate which is mounted inside the lamp shade, and the packing box is mounted at the rear end of the lamp shade. By structurally designing the explosive-proof LED lighting electrical appliance, high photosynthetic efficiency, long service life, instant starting of explosive-proof lighting equipment are realized, and the explosive-proof LED lighting electrical appliance has the advantages of high color rendering, stable light quantity and high safety.

Description

A kind of LED flame proof electric lighting

Technical field

The present invention relates to lighting apparatus, especially a kind of LED flame proof electric lighting.

Background technology

At present, the traditional lighting electrical equipment used in damp and dust atmosphere is had generally to adopt Metal halogen lamp or high-pressure mercury lamp as light source in the industry such as oil, chemical industry.

Although gold-halogen lamp light source light efficiency is higher, but due to reasons such as small volume, brightness height, cause its life-span relatively short, in the just several thousand hours gold-halogen lamp light source life-span of import, another shortcoming of gold-halogen lamp light source is difficulty in starting, after starting, brightness system increases gradually, if it is excessive to start energy, toggle speed is too fast, can affect bulb life, and can not light immediately after extinguishing, could again start after 3 ~ 5 minutes need be waited;

High-pressure mercury lamp has that the life-span is short, light efficiency is low, colour rendering is poor, power factor is low, can not the shortcoming such as thermal starting, luminous flux stability is low.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, propose a kind of LED flame proof electric lighting, specular removal, life-span be long, start instantaneously, colour rendering is high, and luminous flux is stable, security is high.

In order to realize foregoing invention object, the invention provides following technical scheme:

A kind of LED flame proof electric lighting, comprises lampshade, stuffing-box, LED particle installing plate and LED particle,

Described LED particle is arranged on described LED installing plate,

It is inner that described LED installing plate is arranged on described lampshade,

Described stuffing-box is arranged on the rear end of described lampshade.

Described stuffing-box inside seals with explosion-proof clay.

Described lampshade comprises radiator and radiator cowl, and it is outside that described radiator cowl is enclosed within described radiator.

To through hole before and after described radiator centre position is provided with, the explosion-proof clay of described through hole seals.

Also comprise protecgulum and safety glass,

It is inner that described safety glass is fixed on described protecgulum, and described protecgulum is arranged on described radiator front end,

Sealing ring is provided with between described safety glass and described radiator forward end.

Described protecgulum is connected with described radiator nose threads.

The thread that radiator is connected with protecgulum has 5 at least.

Tooth between the thread that described radiator is connected with protecgulum is apart from being at least 1.25mm.

Also comprise bonnet, described bonnet is threaded with described radiator rear end,

The thread that described radiator is connected with described bonnet has 5 at least, and tooth is apart from being at least 1.25mm.

Also comprise anti-explosion terminal box, described anti-explosion terminal box is fixed on the rear portion of described lampshade by contiguous block.

The present invention is by the design to LED flame proof electric lighting structure, not only take full advantage of the advantage of LED illumination device, achieve the specular removal of flame proof electric lighting, life-span length, start instantaneously, colour rendering is high, the advantage that luminous flux is stable, what more make its safety is applied to flame proof lighting field.

Detailed description of the invention

Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.

A kind of LED flame proof electric lighting as Figure 1-4,

Radiator cowl 7 is screwed on radiator 8, and LED installing plate is aluminium base 9, and LED particle is welded on after on aluminium base 9, is screwed in radiator 8 light-source chamber.

Radiator 8 light-source chamber put into by reflection shield 10, and is adjacent to the inwall of light-source chamber.

Protecgulum 13 put into by safety glass 12, gap epoxy sealing is fixed between the two, and protecgulum 13 is connected with radiator 8 nose threads, will pad sealing ring 11 between safety glass 12 and radiator 8, the thread 82 that radiator 8 contacts with protecgulum 13 has 5 at least, and tooth is apart from being at least 1.25mm.

Constant-current supply 6 is put into radiator 8 power source cavity,

Constant-current supply 6 output lead, by radiator 8 intermediate throughholes 81, is welded on aluminium base 9, and fills out the sealing of explosion-proof clay in through hole 81 domestic demand.

Stuffing-box 3 is threaded with bonnet 4 intermediate throughholes,

Stuffing-box 3 cap, through after stuffing-box 3, is locked by constant-current supply 6 input lead, and electronics fluid sealant on radiator 8 power source cavity is filled with, electronic seal need there be constant-current supply 6.

Stuffing-box 3 domestic demand fills up the sealing of explosion-proof clay, and bonnet 4 is threaded with radiator 8 rear end, is lined with sealing ring 5 between bonnet 4 and radiator 8, and the thread 83 that radiator 8 contacts with bonnet has 5 at least, and tooth is apart from being at least 1.25mm.

Contiguous block 2, through contiguous block 2 interstitial hole, is locked on bonnet 4 with screw by constant-current supply 6 input lead,

Constant-current supply 6 input lead is penetrated anti-explosion terminal box 1, and three lead-in wires are locked on the corresponding binding post of terminal box 1.

The setting of sealing ring 11 enables safety glass 12 and radiator 8 front end contact position bear certain impulsive force, effectively extends service life.

The thread quantity that radiator 8 contacts with bonnet 4 with protecgulum 13 and the design of tooth distance, ensure that in flame proof requirement the tooth number of thread connection and the requirement of the degree of depth.

The design of explosion-proof clay is set in stuffing-box 3 and radiator 8 through hole, meets the requirement that in flame proof requirement, no-spark spills.
