Description

Mining double-colored signal lamp

The utility model relates to the mining double-colored signal lamp in a kind of down-hole, the light-emitting component of the mining double-colored signal lamp in particularly a kind of down-hole.

The both current mine truck in some tunnel of down-hole, mine is passer also, for trying to avert accidents, is mounted with red, greensignal light in the tunnel, and the bright indication mine truck of red eye is current, and the bright assignor of greensignal light is current.In the prior art, do not have special-purpose red, greensignal light, the signal lamp in the tunnel is with there being the incandescent lamp explosion-proof lamp of anti-explosion cover to make, and red, greensignal light is to brush red, green painting at the Explosion-proof globe of two incandescent lamp explosion-proof lamps respectively to make.The sort signal lamp, because of incandescent lamp in anti-explosion cover, temperature height when lamp is bright, incandescent lamp bulb is fragile, bulb service life is short.

The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of mining double-colored signal lamp of long service life.

The utility model is realized with the following method.

Invention scheme of the present utility model is to replace incandescent lamp with red, green LED, makes double-colored signal lamp.

For realizing the foregoing invention scheme, mining double-colored signal lamp has the printing opacity can, red light emitting diodes circuit and green LED circuit are arranged in the shell, red, the green LED circuit has rectifier and a plurality of red respectively, green LED, red, series connection or the series connection respectively of light emitting diode in the green LED circuit by the input voltage difference of mining double-colored signal lamp, be together in parallel, owing to be connected in series between light emitting diode, damage the conducting that influences series circuit for preventing from light emitting diode, to open circuit, be parallel with the bypass resistance that the internal resistance with light emitting diode adapts at the two ends of each light emitting diode, bypass resistance is when the circuit of LED conducting, it is luminous not influence the light emitting diode conducting, in a certain light emitting diode, open circuit when damaging, bypass resistance can play the by-path turn-on effect, and unlikely other diode current flows that influence in the series circuit are luminous.Red, the lead-in wire of green LED circuit and the installing hole of mining double-colored signal lamp are arranged respectively on the shell of mining double-colored signal lamp.

During use, be installed to the utility model on the top of underworkings with installing hole, lead-in wire red, green circuit of LED of the present utility model is connected with AC power with switch respectively, by red, the green light emitting diode in switch control the utility model bright, go out, be open to traffic or pedestrian's state with the indication underworkings.

The utility model adopts light emitting diode to make light-emitting component, with incandescent lamp bulb ratio, long service life, saves electric energy.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 4 is the electrical schematic of mining double-colored signal lamp of the circuit of LED of series and parallel;

Fig. 5 is the method for attachment schematic diagram of adjacent light emitting diode in the mining double-colored signal lamp.

Among Fig. 1, Fig. 2, mining double-colored signal lamp has patty printing opacity can 1, red light emitting diodes circuit 3 and green LED circuit 4 are arranged in the shell 1, red, green LED circuit has

rectifier

31,41 and a plurality of red,

green LED

32,42 that connects together respectively, and red, green LED becomes the multilayer concentric annular alternately in patty printing opacity can 1.Red, the lead-in wire 6 of green LED circuit and the installing hole 7 of mining double-colored signal lamp are arranged respectively on the shell of mining double-colored signal lamp.

Fig. 3, among Fig. 4, red, series connection or the series connection of light emitting diode in the green LED circuit by the input voltage difference of mining double-colored signal lamp, be together in parallel, owing to be connected in series between light emitting diode, damage the conducting that influences series circuit for preventing from light emitting diode, to open circuit, be parallel with the bypass resistance 5 that the internal resistance with light emitting diode adapts at the two ends of each light emitting diode, bypass resistance 5 is when the circuit of LED conducting, it is luminous not influence the light emitting diode conducting, in a certain light emitting diode, open circuit when damaging, bypass resistance 5 can play the by-path turn-on effect, and unlikely other diode current flows that influence in the series circuit are luminous.

Among Fig. 5, the connection of the adjacent light emitting diode of series connection is that pin leads with a kind of color LEDs is wrapped in the method for connecting again on the pipe shaft of another kind of color LEDs and links together in the mining double-colored signal lamp, another kind of color LEDs is directly to be cascaded, pin leads is the series connection line, also be that light emitting diode becomes annular skeleton alternately, when series, parallel connects, the light emitting diode of series connection is serially connected in series block as stated above, series block is together in parallel again.

Among Fig. 3, when the voltage at the light emitting diode two ends of connecting is lower than the input voltage of mining double-colored signal lamp, the decompression capacitor 8 of in circuit, can connecting.

The shell usable resins curing of above-mentioned mining double-colored signal lamp is sealed circuit of LED and is made.The shell that is mining double-colored signal lamp is that resin solidification is sealed the circuit of LED layer.
