Description
Technical field
The present invention relates to LED lamp field, especially relate to a kind of mining flame proof locomotive LED headlamp that is applicable to, comprise lamp housing main body and top cover, the built-in reflector of described lamp housing main body, radiator and be fixed on SMD distance light LED chip and the SMD dipped beam LED chip on radiator.
Background technology
Under coal mine, may be full of explosive dust or methane gas, so the light fixture that need to use has explosion-proof flame proof effect in this kind of explosion risk environment.The principle of explosion-proof flame proof is exactly that the back panel wiring of light fixture, electric elements, light-emitting component etc. are closed, and it cannot be contacted with damp or dust.
What under coal mine, use at present is mostly the conventional light source such as incandescent lamp, the feature of this light source is that caloric value is large, easily damage, power consumption is high, use safe not, and lamp source service time can make that temperature is higher when long around, easily explosion caused in explosion risk environment, conventional light source contains the noxious materials such as mercury simultaneously, service life is short, and energy consumption is high.
Also have in the recent period the LED flame proof locomotive light that adopts plurality of LEDs light source to substitute conventional incandescent, it adopts plurality of LEDs, and manufacturing cost is high, and range of exposures is circular mostly, and range of exposures is narrow, without "cut-off"line, and can not realize distance-light illumination simultaneously.
Summary of the invention
The present invention, in order to overcome the deficiencies in the prior art, proposes a kind of mine explosion-suppression locomotive LED headlamp, the LED headlamp that object is to provide is safe, energy-conservation, the life-span is long and thermal diffusivity is good.
In order to solve above-mentioned technical problem, basic solution technical scheme of the present invention is: a kind of mine explosion-suppression type locomotive LED headlamp, comprise cylindrical lamp housing main body, be located at the top cover of this lamp housing main body upper end and be arranged at safety glass lens and the optics module of described lamp housing body front end face, described optics module comprises radiator, reflector and SMD distance light LED chip and SMD dipped beam LED chip; Described radiator forms by tabular base with perpendicular to the smooth panel of this base, and described SMD distance light LED chip and SMD dipped beam LED chip are individually fixed in the mode of paster on two shiny surfaces of smooth panel; Described reflector is provided with the clamp for the smooth panel of accommodating described radiator; Described smooth panel is through being arranged at the clamp on reflector and realizing the fixing of described reflector and described radiator by the mode of mechanical connection.One of difference of this technical scheme of the present invention and traditional technical scheme is, the applied technical scheme of the present invention only adopts the LED chip of two as the light source of illumination, i.e. SMD distance light LED chip and SMD dipped beam LED chip.All the time, conventional LED lamp is all the lamp of pinned, these LED lamp life-spans are not long, and the space taking is larger, cost is also higher, installs also inconvenient, so be as another innovative point of the present invention: two described LED chips are welded on the described smooth panel of radiator by the mode of paster, adopt SMD LED, can make LED compact conformation, energy consumption is low, solved LED lighting lamp power often damages the phenomenon that causes light fixture not work.In addition, also what deserves to be explained is, described SMD distance light LED chip and SMD dipped beam LED chip are welded on smooth panel by the mode of paster, why adopt smooth panel, SMD distance light LED chip is fully contacted, to reach the effect of quick heat radiating with this smooth panel with SMD dipped beam LED chip.
In a kind of mine explosion-suppression type locomotive LED headlamp of the present invention, described clamp middle part has through hole and is convenient to expose described SMD distance light LED chip and SMD dipped beam LED chip to reach the effect of illumination.
In a kind of mine explosion-suppression type locomotive LED headlamp of the present invention, described reflector includes reflective surface, and this reflective surface is combined by multiple micro-structural free form surfaces.Adopt such design, the light source sending from LED chip, after the multipath reflection of these free form surfaces, can better gather light and reflect away.
In a kind of mine explosion-suppression type locomotive LED headlamp of the present invention, described reflector is fixed on described radiator by four screws; Described radiator is prohibited solid on housing by six screws.The device that reflector itself does not have design to be fixedly connected with lamp housing main body, it is by being indirectly fixed in lamp housing main body with radiator is fixing.
In a kind of mine explosion-suppression type locomotive LED headlamp of the present invention, described base is cylindrical base plate.
In a kind of mine explosion-suppression type locomotive LED headlamp of the present invention, described smooth panel is square structure.
In a kind of mine explosion-suppression type locomotive LED headlamp of the present invention, the material of described radiator is aluminum alloy materials.Because aluminium alloy has excellent heat-conductive characteristic, the heat that can fast LED be produced conducts.
The invention has the beneficial effects as follows:
1, the present invention adopts the reflector and two the LED lamps that are combined by multiple micro-structural free form surfaces, the light that can be good at LED lamp to send is launched, in the present invention, SMD dipped beam LED chip is for lower beam illumination, there is the "cut-off"line of headlight for vehicles formula, range of exposures is wide, SMD distance light LED chip is for far lighting in addition, and brightness is high, and irradiation distance is far away.
What 2, the present invention used is that SMD distance light LED chip is connected with smooth panel with SMD dipped beam LED chip and heat sink is set, and can play good radiating effect, and can increase the service life, and reduces power consumption.
