Abstract
The utility model discloses a miner's lamp with auxiliary lighting, which fundamentally solves the problem that the downhole operation can not obtain temporary lighting if a main lamp is damaged. The utility model uses an LED with high brightness as an auxiliary lamp. Thus, the utility model has the advantages of little electricity consumption and long continuous working time. The utility model comprises an explosion proof lamp head, the main lamp, the auxiliary lamp, a reflector lamp bowl and a switching circuit, wherein the reflector lamp bowl is arranged in the explosion proof lamp head and a glass cover is installed on the front side of the explosion proof lamp head by a pressing cover. A conducting wire is connected to a direct current power supply, and a power switch is arranged on the explosion proof lamp head which is arranged on a safety helmet by an installing frame. An explosion proof cavity of the explosion proof lamp head is provided with a circuit board, and the switching circuit is arranged on the circuit board. The main lamp, the auxiliary lamp and a photosensitive diode are arranged on the reflector lamp bowl, the power switch, the main lamp, the auxiliary lamp and the photosensitive diode are connected to the switching circuit by the conducting wire and a conducting wire bundle, and the main lamp, the auxiliary lamp and the photosensitive diode are on the same straight line. The utility model can be used as a replacing product of the existing miner's lamp for downhole illumination.
Description
Technical field:
The utility model relates to the mine lighting technical field, and specifically, it is a kind of mine lamp that has floor light.
Background technology:
During mine underground work, mine lamp is one of indispensable lighting apparatus.At present, the mine lamp in the use is made up of explosion-proof lamp holder, bulb, switch and storage battery substantially, and bulb is installed in the explosion-proof chamber of lamp holder, and lamp holder is installed in the front of safety cap, is the bulb powered illumination with direct current.Because be limited the service life of bulb, especially when underground work, the influence that bulb is shaken, its life-span can become shorter.In the underground work process, in case bulb damages, the miner just can't operate as normal, and change light fixture at mining face under mine is one of condition that produces potential safety hazard, careless slightly, change the small spark that light fixture produces, will cause the seriously generations of security incident such as gas explosion.So, under the prior art situation,, will cause " carry light fixture on the body, feeling about in the dark moves ahead " or embarrassing and worried phenomenon generations such as " work that excuse me " in case bulb damages.Unique solution is exactly the heavily shining bulb of gug, though process is simple, has had a strong impact on production efficiency.
Summary of the invention:
The utility model is that its purpose just provides a kind of when the mine lamp bulb damages suddenly, the mine lamp that has floor light that floor light is lighted automatically to the technological improvement of existing mine lamp.
The purpose of this utility model is to realize like this, the mine lamp that has floor light comprises explosion-proof lamp holder, king light, auxilliary lamp, reflector lamp bowl and on-off circuit, reflector lamp bowl (8) is installed in the explosion-proof lamp holder (3), cloche (7) is installed in the front of explosion-proof lamp holder (3) with gland (6), lead (5) is connected on the dc source, power switch (10) is installed on the explosion-proof lamp holder (3), explosion-proof lamp holder (3) is installed on the safety cap with installing rack (1), it is characterized in that: circuit board (2) is housed in the anti-riot chamber of explosion-proof lamp holder (3), on-off circuit (4) is installed on the circuit board (2), king light (W), auxilliary lamp (L) and photodiode (G) are installed on the reflector lamp bowl (8), lead (11) couples together power switch (10) and on-off circuit (4), bundle conductor (9) is with king light (W), auxilliary lamp (L) and photodiode (G) are connected on the on-off circuit (4), and king light (W), auxilliary lamp (L) and photodiode (G) are point-blank.
The utility model has the advantages that: when fundamentally having solved underground work because of king light damages, problem that just can't temporary lighting; Adopt high-brightness LED as auxilliary lamp, power consumption is little, stream time is long; King light is arranged on the centre of assisting lamp and photodiode, and auxilliary lamp can be imitated luminous, practical entirely.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a right view of the present utility model.
Fig. 3 is an electrical schematic diagram of the present utility model.
The specific embodiment:
Embodiment 1:
Shown in accompanying drawing 1, accompanying drawing 2, the utility model can be changed a social system on the basis of prior art, and explosion-proof lamp holder 3, reflector lamp bowl 8, cloche 7, king light W, gland 6, K switch, installing rack 1 and lead 5 all can adopt the parts of existing mine lamp; On-off circuit 4 is made of triode T, resistance R and photodiode G, and auxilliary lamp L can adopt high-brightness LED, and all electric elements can be buied on market, belong to prior art.Reflector lamp bowl 8 and cloche 7 usefulness glands 6 are installed in the front of explosion-proof lamp holder 3, lead 5 is connected on the dc source, power switch 10 is installed on the explosion-proof lamp holder 3, explosion-proof lamp holder 3 usefulness installing racks 1 are installed on the safety cap, in the anti-riot chamber of explosion-proof lamp holder 3 circuit board 2 is housed, be used to install the electric elements that constitute on-off circuit 4, king light W, auxilliary lamp L and photodiode G are installed on the reflector lamp bowl 8, lead 11 couples together power switch 10 and on-off circuit 4, bundle conductor 9 is with king light W, auxilliary lamp L and photodiode G are connected on the on-off circuit 4, king light W, auxilliary lamp L and photodiode G are provided with point-blank, be in order to damage at king light W, when auxilliary lamp L works, allow king light W play an effect of blocking, so that the full effect of auxilliary lamp L is luminous.
As shown in Figure 3, the K switch closure, circuit enters automatic detection king light W state.After king light W lighted, photodiode G was subjected to the irradiation of light, presents low resistance, and the base potential of triode T reduces, triode T by, auxilliary lamp L does not work.When king light W damaged, king light W circuit disconnected, and photodiode G is because of unglazed irradiation, and presented high value, and electric current is through the base stage conducting of resistance R, triode T, and auxilliary lamp L lights; Because the king light W that is arranged between auxilliary lamp L and the photodiode G plays the effect of blocking, auxilliary lamp L just can be imitated luminous entirely.The operating current of the auxilliary lamp of LED has only about 20MA generally speaking, only is king light 1/35th, so the stream time of the auxilliary lamp of LED can be longer.
