Abstract
The invention relates to a miner's lamp structure, relating to a multifunctional LED miner lamp. The multifunctional LED miner's lamp comprises a casing with an inner cavity, a charging battery socket and a cap support for connecting with a working helmet are provided at the rear portion of the casing and a lens is disposed at the window at the front end of the casing; a large PCB plate for disposing a main control circuit is disposed in the middle portion of the inner cavity of the casing, a reflecting cup made of metal material is dispose in front of the large PCB plate, the bottom of the reflecting cup is a planar surface, a small PCB plate provided with a plurality of LEC light sources adheres tightly on the surface of the reflecting cup bottom, and a pin of the small PCB plate gets through the bottom of the reflecting cup and is welded on the large PCB plate. The invented miner's lamp is provided with a reasonable structure, a good illumination effect and strong heat sinking capability, and gas concentration monitoring and warning is provided therewith.
Description
Technical field
The present invention relates to a kind of mine lamp structure, relate to a kind of Multifunctional LED mine lamp.
Background technology
The old-fashioned mine lamp of traditional employing bulb illumination because of its power consumption is big, must be carried well operations under the heavy battery case, and lamp holder and battery case separate, and the lamp holder power supply must be connected with battery case by cable.Inconvenience is not only used, carried to this structure, also gas explosion safety in production caused very big threat because of the electric leakage sparking causes easily.Simultaneously, cause volume big because old-fashioned mine lamp is to use lead-acid accumulator or alkaline storage battery, the strong leakage of corrosivity and need the special messenger to safeguard, this brings very big trouble for manufacturing, use and old and useless battery treatment etc., and can serious environment pollution.At present existingly be power supply with the lithium ion battery and use the mine lamp product of great power LED as light source, it has, and volume is little, in light weight, good, the free of contamination advantage of security, but existing LED mine lamp product still exists some defectives: 1, existing LED mine lamp product generally adopts conical polishing rotor and toroidal lens cooperation that the illumination circuit is controlled, its toroidal lens not only manufacturing cost is higher, and thicker toroidal lens has reduced luminous flux, influences lighting effect; 2, because the high-power LED light source heating is bigger, and existing product adopts the engineering plastics parts mostly, and topology layout is unreasonable, makes its radiating effect not good, has influenced its service life and reliability; 3, existing product function singleness, and the warning of the methane Concentration Measurement of down-hole needs special device, being not easy to the underground labour can't carry.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of rational in infrastructure, lighting effect good, heat-sinking capability strong and can carry out the Multifunctional LED mine lamp of gas density monitoring, alarming.
Multifunctional LED mine lamp of the present invention includes a housing that has inner chamber, and the housing rear portion is provided with rechargeable battery socket and the cap holder that is used for being connected with working cap, and the window place of housing front end is mounted with lens; Be provided with the big pcb board that is used for settling main control circuit at the middle part of housing inner chamber, be provided with the reflector of a metal material in the place ahead of big pcb board, the bottom of reflector is a plane, have a little pcb board that is mounted with several LEC light sources to be close on the plane of reflector bottom, the pin on the little pcb board passes the bottom of reflector and is welded on the big pcb board.
The interior reflective surface of described reflector is a paraboloidal, and the lens at housing window place, reflector the place ahead are planar lens simultaneously.
Also be mounted with the firedamp sensor and the warning device that are connected in the control circuit on the described housing.
Among the present invention, owing to settle the little pcb board of led light source and reflector bottom to fit tightly, the heat in the time of can making its work distributes rapidly by the metal reflective cup, thereby has improved its heat-sinking capability greatly; Owing to adopted the reflector of paraboloidal and planar lens to cooperate, both can guarantee stronger luminous flux, thin simultaneously planar lens also can reduce light attenuation, reduce manufacture difficulty; In addition, the present invention is integrated in gas monitor and warning device on the mine lamp, both is easy to carry, and has also guaranteed safety in production.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in the figure, housing 1 rear portion of this Multifunctional LED mine lamp is provided with rechargeable battery socket 11 and the cap holder 12 that is used for being connected with working cap, the window place of housing front end is mounted with lens 2, be mounted with the big pcb board 3 that has control circuit in the housing inner chamber, big pcb board the place ahead is provided with the reflector 4 with paraboloidal reflective surface, be fitted with a little pcb board 6 that has several led light sources 5 on the plane 41 of reflector bottom, the pin 61 of little pcb board 6 passes the plane of reflector bottom and is welded on the big pcb board 3.Also be mounted with the warning device 8 (as buzzer, warning lamp etc.) that is used for monitoring the firedamp sensor 7 of gas density and is used for carrying out gas alarming on the housing 1.
