Abstract

The utility model discloses a mining safe illuminating headlamp structure with a supply of a portable lithium battery and a LED lamp. The utility model is characterized in that three semi-conductor light-emitting diodes - one is the main and the other two are used as the assistance, are provided in the same exciter lamp of the headlamp. The radiating fin positioned in the headlamp is provided to conduct the heat of the lamp to the outside of the lamp casing. The illuminating value of the utility model can be selected in 'strong, less-strong, middle, feeble, less-feeble' five levels according to different electrical source in different geologic setting and different condition of the down-hole operation. The utility model not only is portable and practical, but concentrates light uniformly and prolongs a long life. Using the feeble light lamp in emergence, the utility model can save the electric energy and prolong the illuminating time.

Description

Three light source as miner light

Technical field

The emergency lighting equipment that the utility model uses when relating to the underground work of a kind of mine, specifically finger has three light source as miner light of three luminous points.

Background technology

Mining illumination head lamp is the indispensable safety article of miner when underground work.Traditional in the past product is on the safety cap of wearing on the operating personnel's head of going into the well the head lamp of illumination to be set, and heavy lead-acid accumulator is hung over rear waist, has cable to connect between battery and the head lamp.This old-fashioned mine lamp is bigger to each miner's loading weight, and therefore a kind of lighter lithium ion battery having occurred in the eighties of last century later stage makes power supply, makes the head lamp of light source with two semiconductor light-emitting-diodes (being LED).This new-type mine lamp alleviates miner's loading weight greatly, and its gross weight is mostly below 2kg.But the secondary light source in this illumination head lamp that two light sources are arranged is not the center at reflector, therefore influences its light harvesting illuminating effect.Though it also is provided with fin in head lamp inside besides, this fin does not conduct heat to the outer function of housing of head lamp, heat is distributed slowly, and then influence the service life of bulb.

The utility model content

The purpose of this utility model is: overcome the defective that the secondary light source light harvesting is irregular, the heat radiation conduction is not smooth in the existing LED mine lamp, provide to the miner that a kind of light is concentrated, the heat of light source can be transmitted to outside the lamp holder rapidly and distribute, and the safety miner's lamp of energy-conservation delay function is arranged.

The technical scheme of the utility model technical solution problem is: secondary light source in the head lamp and main light source are arranged in the same bulb, and brightness of illumination is adjustable, and has fin to lead to outside the housing of head lamp.The utility model is made up of lithium ion battery, cable, head lamp three parts, wherein also comprises compositions such as charging circuit plate, protection circuit plate, head lamp housing, lampshade, reflector, change-over switch, bulb, lamp socket, fin, charging contact and buckle.Described lithium ion battery is a quad flat box body, and box body is provided with the buckle that can wear waistband outward, and a side is provided with the protection circuit plate in the box body.Described head lamp is a bowl formula shape, is lampshade in front, and ccontaining reflector, bulb and lamp socket are provided with charging circuit plate, fin and change-over switch in the latter half in the first half of head lamp housing.The external knob that is provided with buckle, charging contact and change-over switch of head lamp casing.Described bulb is formed by " one main two is auxilliary " 3 light emitting diode combined, and wherein the main light source relative power is bigger, and two secondary light source relative powers are less.Combining form behind three light source ignitings in the bulb has " auxilliary-main-auxilliary, auxilliary-main, main and auxiliary-auxilliary, auxilliary " to wait 5 kinds, described change-over switch match with the form of lighting of light source and also be provided with " strong, inferior by force, in, weak, inferior a little less than " 5 grades.Described fin is a circular aluminium matter sleeve, its end contacts with the afterbody of bulb, but the heat that the absorption modulation bubble point sends when bright, the other end is told an aluminium flake and is exposed outside housing, purpose is to contact with outside air and to dispel the heat, but aluminium flake during by housing with closely make contact to sealing state on every side, fin with reach bulb on every side and all form state of insulation.Described cable one end is electrically connected with lithium ion battery, protection circuit plate, and the other end is electrically connected with contact, charging circuit plate and the bulb of change-over switch.

The utility model three light source as miner light, its light harvesting performance is good, and the form of lighting can be adjustable at any time according to different situations such as required brightness of illumination, battery service time and energy-conservation time-delays.And the heat that bulb distributed can be transmitted to outside the housing, and good heat dissipation effect all has effect to prolonging bulb life very much.

The specific embodiment

Now contrasting accompanying drawing is further described the utility model: as shown in Figure 4, bulb of the present utility model is formed by 3 light emitting diode combined, ccontaining in transparent spherical shell " one main two is auxilliary " 3 light emitting diodes (LED), wherein the power of main light source 15 is 1w, each power of two secondary light sources 16 is 0.075w, and their leading foot is corresponding with the jack in the lamp socket respectively.A whole set of mine lamp is made up of lithium ion battery 1, cable 2 and head lamp, head lamp comprises head lamp housing 4, reflector 5, change-over switch 6, bulb 7, lamp socket 8, fin 9, charging circuit plate 3, charging contact 10 and buckle 11 etc., and bulb 7 is positioned at the centre focus place of reflector 5.Described lithium ion battery 1, protection circuit plate 13, change-over switch 6, bulb 7 are electrically connected successively by cable 2.The tail end of described fin 9 one end in contact bulbs 7, the other end expose outside head lamp housing 4, and the heat that sends in the time of bulb 7 can being lighted is transmitted to housing and dispels the heat outward.But, therefore closely bond into sealing state with it in the part of fin 9 by head lamp housing 4 for waterproof, explosion-proof and must seal.Described change-over switch 6 be combined into lamp base in lamp socket 8, the bulb 7 " strong, inferior strong, in, weak, inferior weak " type of lighting of five grades of different brightness, can carry out brightness regulation and energy-conservation time-delay on demand.During use, firm in the front portion of safety cap head lamp with buckle 11 cards, lithium ion battery 1 is not got final product on waistband by belt buckle 14.During charging, the charging contact 10 outer head lamp contacts and can charge with the contact of special charging frame.The utility model is owing to be provided with five grades of brightness, and lighting hours is long, especially is fit to operation illumination in the mine under the complex geological condition.
