Description

A kind of LED mine lamp

?

Technical field

The present invention relates to a kind of underground mine use lighting, be specifically related to a kind of LED mine lamp.

Background technology

Mine lamp is the coal miner indispensable illuminations of going into the well, and is extremely dangerous if problem such as mine lamp inefficacy occurs in underground work.Existing mine lamp mainly contains two kinds of old-fashioned mine lamps and the novel cold light source mine lamp that adopts the LED lamp of adopting bulb, and these two kinds of lamps all adopt rechargeable battery powered basically.The bulb mine lamp is to be thrown light on by single bulb, but it is poor because of the height that consumes energy, brightness of illumination, short be eliminated gradually service life.Because mine lamp is strict, must adopt the mine lamp that reliability is high, security performance is strong.And LED adopts led light source to throw light on, and has that very strong illumination brightness, power consumption are low, a long service life, advantage such as safe and reliable, generally adopts the LED mine lamp so show.

In the present LED mine lamp, adopt a plurality of low-power LEDs to be combined as a lamp holder, though cost is low, during actual the use, its hot spot scope is too little, is not suitable for the down-hole and uses more.And a lot of LED mine lamp project organizations are unreasonable, and it is poor optically focused property to occur, light problem such as loose.In addition, a plurality of LED reflectors or lens all be single independently, in LED light fixture production process; To be installed in LED reflector or lens on the fixed head one by one; Or through screw thread or directly clamping, and then gluing or other fixing operations, increased the difficulty that the LED light fixture is produced; And since artificial, fixedly the time, difficult quality guarantee, poor reliability.

What LED mine lamp fin had is made in the lamp holder, and radiating effect is bad, influences the life-span of LED mine lamp; Have better radiating effect if fin is made the part of lamp socket, but need on lamp socket, to do in addition special-purpose charging inlet, and be equipped with special-purpose charger.This mine lamp can not use existing charging rack to concentrate charging, is not easy to unified management, and has improved the cost of mine lamp greatly.

Summary of the invention

The present invention will solve above-mentioned deficiency exactly, provides that a kind of optically focused property is strong, light is even and the high a kind of LED mine lamp of radiating efficiency.

In order to reach above-mentioned effect, the present invention provides a kind of LED mine lamp, comprises lamp socket, lampshade and is located at the inner led light source of lampshade, and the front end of said lampshade is provided with collector lens, and is affixed with lampshade around the said collector lens; The rear end of said lampshade is affixed through radiator and said lamp socket, and said led light source bottom is located at said radiator upper surface.

Said radiator comprises pillar, be arranged at around the pillar interior radiating area and around the outside outer radiating area of radiating area in being arranged at.

Said inside and outside radiating area is equipped with inside and outside fin, is provided with gas channel between said interior fin and the outer fin.

In order to reduce the influence for the power work environment of heat that led light source distributes, said pillar is provided with the power supply that is used for the led light source charging, and said power supply is provided with the charging inlet outside lamp socket.

In order to prevent the lampshade gas leakage of leaking, avoid producing fog, rainbow or short circuit phenomenon, said lampshade and collector lens, radiator junction are equipped with sealing ring.

Said led light source is that middle four little LED lamps of a big LED lamp and periphery are formed.

The light source of LED mine lamp of the present invention is made up of four little LED lamps of a big LED lamp and periphery, has reduced the quantity of LED lamp, reduces manufacturing cost and time; The front end of LED lamp is used for focused light source with the collector lens of a monoblock, improves the optically focused property of light source, guarantees the quality that mine lamp is produced, and enhances productivity.The most of exposed good heat dissipation effect outside of radiator; Power supply is placed on the pillar at radiator center; Because of the height of pillar is higher than the medial and lateral radiating area; Make in power supply and the led light source radiator portion and leave the space; Take away heat through cross-ventilation, intercepted of the influence of led light source heat effectively, promoted the service life of LED light fixture greatly the power work environment.And lamp socket is provided with the charging inlet of power supply, then can utilize the charging rack that oneself has in the mine that the LED mine lamp is concentrated charging, has both made things convenient for the centralized management of LED mine lamp, saves the special charger of LED mine lamp again, greatly reduces the cost of LED mine lamp.

In sum, the present invention has following beneficial effect:

1, the present invention makes the part of lamp socket with fin, most of exposed outside, good heat dissipation effect like this helps prolonging life-span of LED lamp;

2, place the radiator center to be higher than on the pillar of medial and lateral radiating area power supply; Integral body is raised the power supply installation site; Make in power supply and the led light source radiator portion and leave the space; Take away heat through cross-ventilation, intercepted of the influence of led light source heat effectively, promoted the service life of LED light fixture greatly the power work environment.

3, the power source charges interface is led to outside the lamp socket, the charging rack that oneself has in the mine capable of using is concentrated charging to the LED mine lamp, has both made things convenient for the centralized management of LED mine lamp, saves the special charger of LED mine lamp again, greatly reduces the cost of LED mine lamp;

4, lampshade and collector lens, radiator junction are equipped with sealing ring, make good airproof performance in the lampshade, and the gas leakage that prevents to leak strengthens the adaptability under mal-conditions such as mine operation, and guarantees security and convenience at mine operation better;

5, radiating efficiency is high, the radiator of double-deck radiating area inside and outside the present invention adopts, and the reasonable use heat-dissipating space can significantly increase area of dissipation; Simultaneously, between inside and outside radiating area, be provided with gas channel, improve radiating efficiency, expanded service life;

6, LED lamp of the present invention is light small and exquisite, is easy to carry, and the charging interval is short, and lighting hours is long, and the illuminating effect variation along with battery consumption not, brings great convenience to miner's underground work.
