Abstract
The utility model discloses a lighting lamp for an electric locomotive in a mine which has the advantages of high photoelectric conversion efficiency, high reliability, and long service life. The lighting lamp for an electric locomotive in a mine is composed of a power supply for the mine electric locomotive, light emitting diodes with high brightness 3, and a lamp holder 1 or 4; the light emitting diodes with high brightness are connected mutually in series and are uniformly distributed and fixed on the lamp holder 1 or 4; through the concave surface or the convex hemisphere surface of the lamp holder 1, the lamp holder 4, and a reflective lampshade 2, lighting light beams can be focused, and the lighting effects of the lighting lamp for an electric locomotive in a mine can be improved further.
Description
The utility model relates to a kind of lighting device that is used on the mine electric locomotive.
In present prior art, two kinds of lighting devices on the mine electric locomotive are arranged, a kind of employing resistance decompression principle: resistance and 127V incandescent lamp bulb are connected on the dc power supply circuit, but there is following shortcoming in it: the one, because resistor power is too big, cause a large amount of electric energy to be lost in vain; Because the filament of 127V bulb is very thin, when the electric locomotive strenuous vibration, very easily blow simultaneously.Lighting device on the another kind of mine electric locomotive adopts inverter transformation structure, because the inverter circuit complex structure, so poor reliability, fault rate height, maintenance cost are big, in addition, because of using incandescent lamp as light source equally, still has the problem of the easy scaling loss of filament.
The purpose of this utility model provides the mine electric locomotive illuminating lamp of a kind of photoelectric transformation efficiency height, good reliability, long service life, solves the easy scaling loss of incandescent filament in the prior art, electric energy loss is big and problem such as fault rate height.
For achieving the above object, the technical solution of the utility model is: mine electric locomotive illuminating lamp adopts one group of high brightness LED as its illuminator or light source, this group high brightness LED is connected mutually and is fixed on the lamp socket, gets final product flood lighting after connecting mine electric locomotive power supply.
Because the high brightness LED photoelectric transformation efficiency that is adopted is high, so very power saving of this mine electric locomotive illuminating lamp, simultaneously because its circuit is very simple, this diode operation life-span is long, and do not influence the work of other light emitting diode after indivedual luminous tube punch through damage, illuminating effect is also influenced very little, so the reliable operation performance of this mine electric locomotive illuminating lamp improves a lot than prior art.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is that the mine electric locomotive structure of the lighting lamp signal of first embodiment of the utility model is main
View;
Fig. 2 is the right view of mine electric locomotive illuminating lamp shown in Figure 1;
Fig. 3 is that the mine electric locomotive structure of the lighting lamp signal of second embodiment of the utility model is main
View;
Fig. 4 is the left view of mine electric locomotive illuminating lamp shown in Figure 3;
Fig. 5 is mine electric locomotive lighting lamp circuit figure of the present utility model.
The described mine electric locomotive of Fig. 1 illuminating lamp is made up of mine electric locomotive power supply, high brightness LED group 3 and lamp socket 1, after this group high brightness LED is connected mutually, evenly distribute and be fixed on the lamp socket 1, the front shape of this lamp socket 1 can be a rectangle as shown in Figure 1, also can be square, circular or other shape, its surface is the indent face of cylinder or the hemisphere face that curve certain radian as shown in Figure 2, in order to reach spotlight effect preferably.
Fig. 3 has provided the mine electric locomotive illuminating lamp with another structure, its lamp socket 4 is the hemisphere face structure of evagination as shown in Figure 4, high brightness LED group 3 is connected mutually and is distributed on this lamp socket 4, on this lamp socket 4, also be provided with simultaneously a lampshade 2, luminous beam is reflected and focuses on, further improved the illuminating effect of mine electric locomotive illuminating lamp.
The circuit connecting relation of mine electric locomotive illuminating lamp of the present utility model is as shown in Figure 5: its high brightness LED group 3 is by several light emitting diodes D1, D2 ... Dn is in series mutually, high brightness LED group 3 positive poles link to each other with the positive source of mine electric locomotive, and negative pole then is connected on the power cathode of mine electric locomotive.
Meet following formula in the mine electric locomotive illuminating lamp of the present utility model between the number of high brightness LED and the mine electric locomotive supply voltage value:
n＝V1/V2
Wherein: n---the number of high brightness LED
V1---mine electric locomotive supply voltage
V2---each high brightness LED rated operational voltage
The power supply of mine electric locomotive is generally direct current, and have two grades of rated operational voltage values usually: i.e. 250V and 550V, it is the commercially available prod of 3.6V that light emitting diode in the high brightness LED group 3 of the present utility model can be selected rated operational voltage V2 for use, when mine electric locomotive supply voltage V1=250V, according to above-mentioned formula, the number of diodes n of high brightness LED group 3 is 70.When mine electric locomotive supply voltage was V1=550V, then number of diodes n was 152.
Mine electric locomotive illuminating lamp of the present utility model is after connecting mine electric locomotive power supply, all high brightness LEDs are simultaneously luminous, assemble an illuminator, the lamp socket of concave surface or lampshade can focus on the light beam of this light emitting diode group, form the high light light beam one, thereby provide good illuminating effect for the mine electric locomotive.
