It is light source that the utility model has mainly adopted LED, thereby it is low to have operating temperature, and the light efficiency height is energy-conservation, safe and reliable, and long service life need not change the bulb, and simple and reasonable, and convenient disassembly has advantages such as complete intrinsic safety.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, the upper end of lamp body 4 and the sealing ring above it 9, PC lampshade 5 and lampshade ring 8 have constituted the intrinsic safety chamber of light fixture, LED lamp bar 6 bonds on the cooling stand 7 with enough area of dissipations by thermal conductive insulation glue, and cooling stand 7 is fixed in the intrinsic safety chamber, upper end of housing by screw; The intrinsic safety chamber makes the work that light fixture can intrinsic safety.The lower end of lamp body and light cover 15 constitutes the explosion-proof chamber of light fixtures, makes installation power panel 10 within it can export intrinsic safety electric source and drives LED operate as normal in the intrinsic safety chamber; Power switch 11 is installed in the explosion-proof chamber, and the switch knob 12 outer by switch shaft on the switch and housing is connected.Switch knob 12 can rotate the operation that realizes the "on" and "off" of light fixture; Cable clamp nut 3 makes the explosion-proof chamber sealing after by the nut bore on the housing cable being inserted explosion-proof chamber.Magnet frame 1 is welded to connect with light cover 15; Strong magnets 14 is fixed on the light cover 15 by magnet frame 1, lamp body is adsorbed on the top board of working face coal excavation apparatus by the strong magnets on the light cover 14, the enough suction of strong magnets 14 assurances adheres to light fixture reliably and can not fall down, and utilizes magnet tightly to inhale on top board 360 degree rotation directions to come the irradiating angle of light fixture is adjusted.The magnet frame 1 of unloading on lamp handle 13 and the light cover of " L " type is connected by pin, when unloading lamp handle 13 and outwards moving, lamp handle 13 rotations of unloading of " L " type separate the top board of light fixture and coal excavation apparatus, just lamp can be taken off easily with hand steered firmly light fixture handle 2, handle 2 is to fix by the handle button that is welded on the lamp housing again.The intrinsic safety chamber and the explosion-proof chamber of light fixture are isolated, and the intrinsic safety electric source of by the explosion-proof wiring post power panel being exported between them is connected with LED.

Described lamp body, it has constituted top intrinsic safety chamber and following explosion-proof chamber by the dividing plate of centre, intrinsic safety chamber and explosion-proof chamber all are independent sealed, lamp body has certain frame for movement intensity, the orchid that sends out of its infraoral is the explosion-proof faying face with specialty processing, the hole of the switch shaft above it also is through processing explosion-proof faying face, the nut bore of its clamp nut also is to have professional explosion-proof faying face, whole cavity satisfies every performance requirement of explosion-proof electric apparatus fully, plays auxiliary effect of assisting the led support heat radiation simultaneously; Described light cover, its flange brim edge also are the explosion-proof faying faces that has through specialty processing, cooperate with explosion-proof faying face on the lamp body and have constituted the explosion-proof chamber of light fixture; Described PC cover, its intensity and printing opacity are very good, can resist various impacts and mechanical wear; Described strong magnets is to adopt highdensity rubidium iron boron compression to form, and high-low temperature resistant and outside mechanical shock and do not demagnetize are enough to guarantee on the top board of the light fixture work that is fixed on reliably and with long-term; Described led light source is to adopt present light efficiency to reach the LED of single the high-power 1W of 90LM/W, has photochromic stablizing, and angle is big, the plurality of advantages that light decay is little; Described cooling stand is the requirement that can guarantee the normal heat radiation of 20 LEDs through calculating, have high thermal conductivity factor and enough area of dissipation and big heat dissipation channel, junction temperature is lower than 50 degree during with assurance LED long-term work thereon, and it is fan-shaped to increase the rising angle of light fixture that 4 row's led light sources are arranged in; Described clamp nut the sealing, also has the effect that prevents ore deposit cable pull-off after assurance ore deposit cable penetrates housing; Described handle plays the carrying light fixture at ordinary times and acts on easily, can play booster action simultaneously when unloading lamp; The described lamp handle that unloads is by the hinge lever principle, just lamp can be taken off by simple rotation when unloading lamp.

The input power supply that the utility model utilizes the intrinsic safety electric source plate will exchange input 127V converts the intrinsic safety dc source of two-way 18V/600mA to and delivers to the intrinsic safety chamber.Drive 2 paths of LEDs lamp bar work respectively, 5 LEDs luminous tube parallel operations on 2 cluster of lamps, ornamental bars on every road can satisfy the requirement of intrinsic safety simultaneously when having guaranteed to work under LED rated voltage current condition.Intrinsic safety electric source has overvoltage protection, overcurrent protection and short-circuit protection function, thereby has guaranteed the work of the LED safety in the intrinsic safety chamber; The PC lampshade has guaranteed the sealing in intrinsic safety chamber.
