Described LED installing plate is installed in described lampshade inside,

Described stuffing-box is installed in the rear end of described lampshade.

Described stuffing-box is inner with explosion-proof clay sealing.

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

To through hole, described through hole sealed with explosion-proof clay before and after described radiator centre position was provided with.

Also comprise protecgulum and safety glass,

Described safety glass is fixed on described protecgulum inside, and described protecgulum is installed in described radiator front end,

Be provided with sealing ring between described safety glass and the described radiator front end end.

Described protecgulum is threaded with described radiator front end.

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

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

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

The thread that is connected with described bonnet on the described radiator 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 passes through LED flame proof electric lighting structure Design, not only take full advantage of the advantage of LED lighting apparatus, realized the high light efficiency of flame proof electric lighting, long, moment startup of life-span, the colour rendering height, the advantage that luminous flux is stable, what more make its safety is applied to the flame proof lighting field.

The specific embodiment

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

A kind of LED flame proof electric lighting shown in Fig. 1-4,

Radiator cowl 7 usefulness screws are fixed on the radiator 8, and the LED installing plate is aluminium base 9, after the LED particle is welded on the aluminium base 9, are fixed in radiator 8 light-source chamber with screw.

Reflection shield 10 is put into radiator 8 light-source chamber, and is adjacent to the inwall of light-source chamber.

Safety glass 12 is put into protecgulum 13, the slit is fixed with epoxy sealing between the two, and protecgulum 13 is threaded with radiator 8 front ends, will fill up sealing ring 11 between safety glass 12 and the radiator 8, the thread 82 that contacts with protecgulum 13 on the radiator 8 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 cavities,

Constant-current supply 6 output leads are welded on the aluminium base 9 by radiator 8 intermediate throughholes 81, and fill out explosion-proof clay sealing in through hole 81 domestic demands.

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

After constant-current supply 6 input leads pass stuffing-box 3, with the locking of stuffing-box 3 caps, electronics fluid sealant on radiator 8 power source cavities are irritated, electronic seal need there be constant-current supply 6.

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

Constant-current supply 6 input leads pass contiguous block 2 interstitial holes, with screw contiguous block 2 are locked on the bonnet 4,

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

The setting of sealing ring 11 makes safety glass 12 and radiator 8 front end contact positions can bear certain impulsive force, has effectively prolonged service life.

The thread quantity that contacts with bonnet 4 with protecgulum 13 on the radiator 8 and the design of tooth distance have guaranteed in the 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 holes, satisfies the requirement that no-spark spills in the flame proof requirement.

The present invention passes through LED flame proof electric lighting structure Design, not only take full advantage of the advantage of LED lighting apparatus, realized the high light efficiency of flame proof electric lighting, long, moment startup of life-span, the colour rendering height, the advantage that luminous flux is stable, what more make its safety is applied to the flame proof lighting field.
