Abstract
An LED lighting fixture for a mine consists of an explosion-proof box body and an intrinsic safety box body; the intrinsic safety box body is connected onto the explosion-proof box body; the internal part of the intrinsic safety box body is fixedly provided with an aluminum heat dissipation substrate and an LED light source and the surface of the intrinsic safety box body is sealed with a frosted PC pipe; a power transformer and an LED drive power are installed in the explosion-proof box body and are in circuit connection with an LED light source; an incoming line bell mouth is arranged on the explosion-proof box body; and a power line is connected with the power transformer and the LED drive power through the incoming line bell mouth. A battery lead bell mouth is also arranged on the explosion-proof box body, the power of which can be supplied by the battery. The LED lighting fixture for the mine is designed aiming at the poor production environment of the mine, and has the advantages of energy conservation, safety, long service life, free maintenance, and strong pertinence.
Description
Technical field
The utility model relates to a kind of mining lighting, is specifically related to a kind of mining LED lighting.
Background technology
Common mining lighting is divided into two kinds at present: flame-proof type fluorescent lamp and flame-proof type incandescent lamp.There is following shortcoming in they when using in the colliery:
1, power consumption is big
One day 24 hours power consumption 960W of a common 40W fluorescent tube, a month power consumption 28800W.Because fluorescent lamp and incandescent lamp use amount are huge under the coal mine, so power consumption is very surprising.
2, the life-span is short, maintenance cost is high
The life-span of ordinary incandescent lamp, about about 1000 hours, the life-span of common fluorescent lamp was greatly about about 2000 hours greatly.But under this complexity in mine and rugged environment, its performance and reliability are had a greatly reduced quality, and the life-span of fluorescent lamp is often less than a week in real work.Enterprise only changes the fluorescent lamp or the incandescent lamp that damage and just needs the no small man power and material of cost in normal activity in production.
Summary of the invention
The purpose of this utility model be at the mine production environment abominable and provide a kind of energy-conservation, reliable, the life-span long, non-maintaining mining LED lighting
Mining LED lighting of the present utility model is made up of flameproof cabinet and intrinsic safety casing, the intrinsic safety casing is connected on the flameproof cabinet, in the intrinsic safety casing, be fixed with aluminium matter heat-radiating substrate, one group of led light source is arranged and is installed on the aluminium matter heat-radiating substrate, the surface of the intrinsic safety casing frosted PC seal of tube, power transformer and LED driving power are installed in the flameproof cabinet, and be connected with the led light source circuit, be provided with the entrance bell that is used to connect power line on flameproof cabinet, power line is connected with the LED driving power with power transformer by it.
Simultaneously, on flameproof cabinet, be provided with an outlet horn mouth that is used to connect power outlet.Generally speaking, the entrance bell on the flameproof cabinet is connected power line, and outlet horn mouth string goes out power line and is connected with the entrance bell of next mining LED lighting, makes all LED lamps luminous.
On flameproof cabinet, also be provided with a battery lead-in wire horn mouth that is used to connect battery, can connect battery under special circumstances, when some occasion does not have power supply or uncomfortable splice grafting power supply, can adopt battery-driven method, thereby improve the use flexibility of mining LED lighting.
Wiring horn mouth on the flameproof cabinet is identical with common explosion-proof switch, seals by sealing ring and sealing gasket, is explosion-proof wiring horn mouth.Simultaneously, between frosted PC pipe and intrinsic safety casing, also adopt the rubber seal sealing, can play good waterproof effect.
Mining LED lighting of the present utility model has the following advantages:
1, the power consumption of energy-saving LED has only 1/5 or 1/10 of fluorescent lamp or incandescent lamp, and the LED operating voltage is low, adopts the DC driven mode, and is low in energy consumption, and the power conversion rate height is more energy-conservation more than 80% than conventional light source under the equal illumination effect.
2, safe LED is the solid cold light source, can not produce electric spark, and is safe in utilization, belongs to typical green, environmental protection lighting light source.
3, long service life LED volume is little, and is in light weight, firm in structure, and there are not easily shortcomings such as burning, heat deposition, light decay of filament light-emitting in anti-vibration, can reach 60,000～100,000 hours service life, is more than 10 times of conventional light source service life.
The mining lighting of LED of the present utility model is to design at the abominable actual conditions of mine production environment, has energy-conservation, safety, long, non-maintaining, with strong points characteristics of life-span.
Description of drawings
Fig. 1 is the structural representation of the mining lighting of the utility model LED;
Fig. 2 is the side structure schematic diagram of the mining lighting of the utility model LED.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1 and Figure 2, form mining LED lighting by flameproof cabinet 5 and intrinsic safety casing 7.Power transformer 2 and LED driving power 3 are installed in flameproof cabinet 5, and the surface of flameproof cabinet 5 is provided with an explosion-proof entrance bell 1, an explosion-proof outlet horn mouth 6 and an explosion-proof battery lead-in wire horn mouth 4.Intrinsic safety casing 7 is bonded on the flameproof cabinet 5, and led light source 8 and aluminium matter heat-radiating substrate 10 are housed in intrinsic safety casing 7, and frosted PC manages 9 outer covers as intrinsic safety casing 7, is used to seal intrinsic safety casing 7.Flameproof cabinet 5 and intrinsic safety casing 7 all with the rubber seal sealing, play waterproof effect.
