Abstract

A light mining safety helmet lamp pertains to industry safety equipment field, comprising a lighting lamp, a lamp cap shell, a reflector, a lamp surface glass and a power supply. The utility model is characterized in that: the lighting lamp adopts that components are connected in parallel with a lighting emitting diode (LED), and the components are connected with the circuit board, and the power supply is batteries. The safety helmet lamp is light, flexible, low electricity consumptive, has long service life, not needed to carry storage battery, and a cold light is used, so heat or electrical sparkle impact can not be caused, therefore, the utility model is safe and reliable.

Description

Portable mining safety helmet lamp

Technical field

The utility model belongs to the industry security apparatus field, specially refers to be used for mining industry, a kind of portable mining safety helmet lamp.

Background technology

In the mining industry, under mine during operation, the safety precaution facility is vital major issue, country attaches great importance to, at mining safety helmet lamp, also formulated national standard specially, think portable lighting under the mine, belong to special type electrical equipment " S ", in order to prevent to cause the possibility of the great gas explosion of nocuity, made strict regulation in the standard, in mine lamp, the selection of external member, connect, all made concrete, strict restriction, in prior art, the used safety cap lamp of miner is to be power supply with the battery, ordinary incandescent lamp is the portable illuminating lamp of lamp holder, its illumination requirement is not less than 400Lx and 200Lx under 1m distance far away, but its weight is considerable, general full lamp weight, comprise always total (2.1-2.5) kilogram weight (referring to GB GB7957-87) of the battery that hangs on one's waist, this is for being in the hard continuously miner who operates under the adverse circumstances, what significantly increased them bears pressure and degree of fatigue, and the incandescent lamp breakage that in a single day meets accident, the spark that its heat filament produces and cause that the danger of gas explosion is very big, in order thoroughly to solve above-mentioned potential safety hazard and to alleviate miner's fatigue strength, the applicant proposes a kind of brand-new scheme, utilize the lighting source of light emitting diode,, do not contain heat filament because it is a cold light source as safety cap lamp, can significantly improve the safe coefficient of well operations, obviously alleviate miner's pressure burden again with ultraportable weight.The applicant is in a patent 03261752.6 " light-emitting diode (LED) illuminating lamp " of first to file, be very full on light emitting diode (common name LED), as the solid light source technology,, in countless various devices, various incandescent lamp bulbs have been replaced owing to reliability height, efficiency height; Recently, looked forward to the development prospect of LED light emitting diode on some public publications of home and abroad, prophesy LED will finally replace used incandescent lamp and the fluorescent lamp of global family and office, novel white light source will reduce global energy consumption significantly, the portable mining safety helmet lamp that we developed just is based on a kind of like this example of further opening up, utilizing on LED superiority basis.

Summary of the invention

The utility model technical issues that need to address are at existing mining safety helmet lamp, because it is heavier to exist overall weight, increases miner's load-bearing and press; Exist the possibility of potential safety hazard big simultaneously, in order to overcome above-mentioned defective, just redesigning a kind of LED of selecting for use is the portable mining safety helmet lamp of illumination.In order to reach this purpose, realize by the following technical solutions, a kind of portable mining safety helmet lamp, comprise illuminating lamp, lamp shell, reflector, lamp surface glass and power supply, it is characterized in that, this illuminating lamp is selected LED series and parallel assembly for use, and assembly is connected on the circuit board, and its power supply is selected battery for use.Described light emitting diode string, number in parallel are selected for use according to required intensity of illumination, and it is connected to 3～9V powered battery, and through the overtesting identification, its illumination has met the GB requirement.Described battery location can be fixed on the lamp shell afterbody, also can be placed on battery case that lamp shell separates in and be fixed on the safety cap.Whole lamp holder is stuck in by the clip on the lamp shell that the miner is experienced is easy to use.The beneficial effects of the utility model are, this safety cap lamp is light, flexible, and power consumption is little, and the life-span is long, does not need to carry battery, owing to be cold light source, even the breakage of lamp face can not cause heating or electric spark bump yet, thereby safety, reliable.This safety cap can also be expanded scopes such as using diving, underwater operation and building underground construction, tunneling operation.

The portable mining safety helmet lamp structural representation of Fig. 1 for installing

Fig. 2 is a used circuit board layout diagram in the above-mentioned safety cap lamp

Specific implementation method

With reference to Fig. 1, represent a portable safety cap lamp structural representation that is installed on the miner's safety helmet, 1 is string among the figure, LED assembly in parallel, the number of LED is intensity of illumination and select varying number for use as required, optional 20 of this example, speculum 2 is for surrounding the taper surface in a week, and this reflecting surface also can be placed on around the LED assembly with parabolic, the glass plate washer 3 in lamp the place ahead is fixed in the girdle of lamp housing 5 front portions, LED assembly back is a circuit board 4, and it is connected with switch 6 and battery 7, battery 7 can be positioned at the rear portion of lamp housing 5, as this example, also can separate with lamp housing, be placed on other positions that are fixed on safety cap in the battery case.The 8th, be connected a clip on the lamp housing, it is clipped in the edge mouth place of safety cap 9 regularly.With reference to Fig. 2, the circuit connecting relation figure of circuit 4 parts in the expression safety cap lamp, the LED assembly 1 of series and parallel is connected to battery 7 by fuse and switch 6.

Claims (3)

1, a kind of portable mining safety helmet lamp, comprise illuminating lamp, lamp shell, reflector, lamp surface glass and power supply, it is characterized in that this illuminating lamp is selected LED series and parallel assembly for use, assembly is connected on the circuit board, and its power supply is selected battery for use.

2, portable safety cap lamp according to claim 1 is characterized in that, described light emitting diode string, number in parallel are selected for use according to required intensity of illumination, and it is connected to 3～9V powered battery,
