The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
The utility model mining signal display lamp shown in Figure 1 is mainly by lamp holder, transparent outer cover, wiring board (6,11), red and green ultra-high brightness LED (10) and an outer external dropping resistor (R1) formation of lamp.Lamp holder is made of bump (1), insulating glass (2), screw sheel (3), epoxy resin supplement (4).Transparent outer cover is by cover (5) on the shell, and cover (9) at the bottom of the shell is by the fastening one of self-tapping screw (7).Wiring board divides main circuit board (6) and auxiliary line plate (11), and the two lays respectively at upper and lower end in the bulb transparent outer cover.Two wiring boards are except the soldering of electronic components forming circuit, the upper and lower support of the high-brightness LED of double as series connection bunchiness also, the red high-brightness LED of series connection bunchiness and green high-brightness LED (10) evenly respectively are vertically and are arranged in the transparent outer cover between two wiring boards.Number red and green LED (10) respectively is 12～30.
Deployment scenarios at main circuit board shown in Fig. 2,3 (6) and the last electronic component (8,12) of auxiliary line plate (11).Arrow among the figure is represented the tie point of two wiring boards and red and green high-brightness LED, and R+, R-represent the tie point of the positive and negative end of the red high-brightness LED of connecting, and G+, G-represent the tie point of the positive and negative end of green high-brightness LED of connecting.The element of auxiliary line plate (11) has only a resistance (R6), and it is connected with the resistance (R6) on the main circuit board (6) and uses as a resistance.
The circuit of the utility model mining signal display lamp shown in Figure 4.It comprises the red high-brightness LED of control series connection and luminous respectively on-off circuit, AC power rectification circuit and the lamp guest performer external dropping resistor (R1) between lamp holder and AC power of green high-brightness LED of series connection.(D1～D4) rectification, direct current output cathode end is divided into two-way: one tunnel branch hydraulic circuit that constitutes through three resistance (R3, R4, R5) is to negative pole through rectifier bridge for the 127V AC supply voltage.Wherein go up divider resistance and connect with two resistance (R3, R4), following divider resistance (R5) two ends shunt capacitances (C1), dividing point connect the base stage of transistor (S1) through resistance (R7), Zener diode (DW1); Another road is divided into three the tunnel: the one tunnel and connects the colelctor electrode of triode (S1) through resistance (R8) after resistance (R2) step-down; Another road through the green LED (LED1) of several series connection and with it the series connection resistance (R6), connect triode (S1) colelctor electrode; Third Road connects the colelctor electrode of transistor (S2) through the red light emitting diodes (LED2) of several series connection.The emitter stage of two triodes (S1, S2) connects direct current output negative pole end.The colelctor electrode of triode (S1) has one the tunnel to connect triode (S2) base stage through Zener diode (DW2), has another road to connect power cathode through electric capacity (C2).The redness of series connection and green LED (LED2, LED1) are pressed the collector loop that forward inserts triode (S1), and promptly their positive pole connects positive source.DT represents lamp holder, and the outer meeting resistance of series connection (R1) can place lamp socket.Rated supply voltage exchanges 127V, allows voltage range 90～150V.Voltage stablize usefulness two the series connection Zener diodes (DW3, DW4) can use, also can.
Operation principle:
1. when sealing in outer meeting resistance (R1) before lamp holder, because the alternating current in the input lamp is pressed with certain reduction, rectifier output voltage also reduces.At this moment, DC voltage is through a minute hydraulic circuit dividing potential drop, the voltage of dividing point, be the voltage on the divider resistance (R5), deficiency is so that Zener diode (DW1) reverse-conducting, transistor (S1) base stage does not have base current, triode (S1) ends, and its current collection is high potential very, and green LED (LED1) does not work.Because triode (S1) current collection is high potential very, lower because of Zener diode (DW2) breakdown reverse voltage again, at this moment, can make Zener diode (DW2) reverse-conducting, the base stage of transistor (S2) produces base current, triode (S2) conducting, (LED2) is luminous for red light emitting diodes.
2. when before lamp holder, do not seal in outer meeting resistance (R1), when making the 127V alternating voltage directly be added to lamp holder, because the alternating voltage in the input lamp is higher, rectifier output voltage is also high, divide the voltage of hydraulic circuit dividing point to be enough to make Zener diode (DW1) reverse-conducting, provide base current through resistance (R7), Zener diode (DW1) for transistor (S1) base stage, make triode (S1) conducting, (LED1) is luminous for green LED.Triode (S1) conducting, triode (S1) colelctor electrode is in electronegative potential, oppositely not conducting of Zener diode (DW2), the base stage of transistor (S2) does not have base current, and triode (S2) ends, and red light emitting diodes (LED2) does not work.Because triode (S1) conducting is to the locking action of triode (S2) base potential, red and green high-brightness LED can only be luminous respectively, and the red and luminous conversion of green LED by outer meeting resistance (R1) control, and can not be simultaneously luminous.Two electric capacity (C1, C2) play anti-interference effect.
Red high-brightness LED and green high-brightness LED in the circuit can replace mutually, and when making the external dropping resistor of lamp holder string (R1), green LED is luminous, and red LED does not work; When not going here and there external dropping resistor (R1), red LED is luminous, and green LED does not work.
In circuit, the numerical value apolegamy that influences resistance, Zener diode (DW1, DW2) and the outer meeting resistance elements such as (R1) of two triodes (S1, S2) base current is wanted suitably.Last divider resistance is connected with two resistance (R3, R4), and dropping resistor (R2) is connected with two resistance with two resistance parallel connections, resistance (R6), and is all used for ease of adjusting.
External voltage drop element also can adopt external diode.After sealing in diode, form halfwave rectifier, reduce the DC voltage of rectification output, triode (S1) is not worked by, green LED 1, and triode (S2) conducting, red LED 2 are luminous.When not going here and there external diode, then green LED is luminous, and red LED does not work, luminous the changing of promptly red green LED.At this moment, resistance need elect in addition in the circuit.It is pointed out that when adopting external diode, can produce communication apparatus and disturb.Avoid using with communication apparatus.
The luminous respectively transistor switching circuit of the red and green high-brightness LED of above-mentioned control also can substitute with the on-off circuit of formations such as FET, IGCT.
The lamp holder of this lamp removes and adopts screw type, also can adopt direct insertion.This lamp is only made signal lamp usefulness, can not make lighting and use.Use does not have explosion insulation performance separately, must put into explosion-proof lamp in the down-hole and use.
