Abstract
The utility model relates to an LED cold light source cap lamp, which aims at solving the problems of short service life, high power consumption, big volume of matching power supply and insecurity, etc., which exist in the past cap lamp bulbs. The cap lamp essentially comprises a group lens and an LED luminescent tube point light source. The LED luminescent tube point light source is arranged at the focus on one side of the group lens; each convex lens is provided with one LED luminescent tube point light source, which consists of a printed circuit board and an LED luminescent tube. The utility model has the advantages of good light condensing performance, low power consumption, long service life, small volume of the matching power supply, light weight and portability; and as the power source is cold power source, the utility model does not cause gas explosion when used in coal mine wells.
Description
The utility model relates to LED cold light source mine lamp, is widely used in fields such as all kinds of mines, down-hole and rescue.
In background technology, present domestic mine lamp adopts 4V direct current, the mining bulb of 0.6～0.7A, parabolic mirror, convex lens combining structure mostly.Matching used power volume is big, and weight is also bigger, about 2～2.5 kilograms, carries inconvenience; Bulb power consumption is big, and temperature can can't reach essential safety up to several Baidu when bulb used; And service life is short, needs often to change; Most importantly be used in coal mine following time, if glass lens and bulb fragmentation, because the too high meeting of filament temperature causes gas explosion.Or power supply short circuit sparking meeting causes gas explosion, causes casualties and material produces loss.
The purpose of this utility model is the weak point that overcomes in the above-mentioned technology, develop a kind of new LED cold light source mine lamp, it is big to solve mining bulb power consumption of past, matching used power volume greatly and do not belong to essential safe type and easily cause problems such as coal mine gas from explosion, reach long service life, power consumption is low, and matching used power volume is little, the low situation that can not set off an explosion of temperature during owing to work.
Technical solution of the present utility model is as follows:
Comprise: have in the lamp holder (5) of optically focused characteristic LED luminous tube (3) is arranged, it is characterized in that: there is LED luminous tube (3) spot light in printed board of being assemblied in (4) at the focus place of group's formula lens (1) one side, form area source by printed board (4) and LED luminous tube (3) spot light, all corresponding LED luminous tube (3) spot light in each convex lens (2) the focus place in group's formula lens (1).
Technical solution of the present utility model also comprises:
Each LED luminous tube (3) center line convex lens pairing with it (2) main shaft can match, and forms collimated light beam; Can not match yet, form convergent pencil of rays.
Advantage of the present utility model and effect:
1. owing to adopt the LED luminous tube, light source life can reach 100,000 hours, 1000 hours the service life of bulb in the former technology.
2. because LED luminous tube when luminous, light energy use efficiency is higher, and temperature at room temperature only improves 20～30 degree, can not cause gas explosion in underground coal mines when glass lens fragmentation and power supply short circuit.
3. the utility model is widely used in fields such as all kinds of mines, down-hole and rescue.
Description of drawings of the present utility model is as follows: Fig. 1 is a structural representation of not being with the shading eaves, and Fig. 2 is the structural representation of band shading eaves, and Fig. 3 is an A portion enlarged diagram among Fig. 2; Above-mentioned number in the figure is described as follows:
1, group's formula lens 2, convex lens 3, LED luminous tube
4, printed board 5, lamp holder 6, lens shading eaves
Following adjoint is done further auspicious stating: referring to Fig. 1, assembling group's formula lens 1 and area source in lamp holder 5, wherein area source is made up of printed board 4 and LED luminous tube 3, referring to Fig. 1, Fig. 2, be distributed with convex lens 2 on group's formula lens 1, each focal distance f place, convex lens 2 top is a focus, corresponding each spot light LED luminous tube 3, focal distance f decides according to not homochromy spot light LED luminous tube 3, the light source applications of this lens 1 and opposite position is the flesh and blood of the invention for the intrinsic safety light source under the particular surroundings in colliery, also is the essential features of finishing goal of the invention.Each convex lens 2 center line and LED luminous tube 3 main shafts match, and form collimated light beam; Misfit, can form convergent pencil of rays.Only in this way, just can reach the illuminance that mining lamp needs.
Claims (4)
1, LED cold light source mine lamp, comprise: have in the lamp holder (5) of optically focused characteristic LED luminous tube (3) is arranged, it is characterized in that: the focus place of group's formula lens (1) one side is assemblied in printed board (4) and LED luminous tube (3) spot light, form area source by printed board (4) and LED luminous tube (3) spot light, an all corresponding LED luminous tube (3) spot light in the focus place of each convex lens (2) in group's formula lens (1).
2, LED cold light source mine lamp according to claim 1 is characterized in that: the main shaft of the center line convex lens pairing with it (2) of each LED luminous tube (3) can match, and forms collimated light beam; Can not match yet, form convergent pencil of rays.
3, LED cold light source mine lamp according to claim 1 is characterized in that: described group's formula lens (1) can be with lens shading eaves (6), also can not be with lens shading eaves (6).
