Abstract
The utility model relates to an emergency illuminating lamp, which comprises a shell, a transparent cover, an LED (Light-Emitting Diode), a DC (Direct Current) battery, an electronic component circuit board and an LED circuit board. The emergency illuminating lamp is characterized by also comprising a pull switch; the pull switch is fixed in the shell; and the stay cord of the pull switch extends out of the shell after passing through a lead hole on the transparent cover. Due to the adoption of such a structure and the setting of the pull switch, when the emergency illuminating lamp is hung on high, a power supply can be conveniently turned on and off through the stay cord of the pull switch, i.e. the use is very convenient. The utility model overcomes the defect that in the prior art, turning on and off the power supply is inconvenient by using a key switch when the emergency illuminating lamp is hung on high.

Fig. 2 is the circuit diagram of emergency light
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, emergency light comprises shell 1, transparency cover 2, LED light emitting diode (not identifying among the figure), DC battery 3, AC power-supplying circuit, electronic element circuit plate 4 and LED wiring board 5, also comprise a stay-supported switch 6, described stay-supported switch 6 is fixed in the shell 1, and the wire guide that the stay cord 61 of stay-supported switch 6 passes on the transparency cover 2 stretches out shell 1.
As further improvement of the utility model, also comprise a lamp holder 7, lamp holder 7 is connected with AC power-supplying circuit on the electronic element circuit plate.Described lamp holder 7 can be a screw socket, also can be bayonet socket.Adopt such structure, can be installed in the general Down lamp of smallpox, promptly can be used as emergency light again as illuminating lamp.
Described stay-supported switch 6 is fixed on the electronic element circuit plate 4, and stay cord 61 passes the wire guide on electronic circuit board 4, LED wiring board 5 and the transparency cover 2, stretches out transparency cover 2.
" R " expression resistance among the figure in Fig. 2, the numeral sequence number of back, " Q " represents triode, the numeral sequence number of back, " C " represents electric capacity, the numeral sequence number of back, and " D " represents diode, the numeral sequence number of back, " ZD " represents Zener diode
The numeral sequence number of back, " E " represents battery, " LED " represents light emitting diode, the numeral sequence number of back, " SW " expression stay-supported switch.
As shown in Figure 2, the AC power-supplying circuit comprises capacitor C 1, C2, resistance R 1, R3～R8, diode D1～D5, triode Q1, Zener diode ZD1, pull switch SW.The DC power-supplying circuit comprises resistance R 9～R12, diode D6～D8, triode Q2, Q3, stay-supported switch SW.
Shown in Figure 2, AC power-supplying circuit comprises rectifier charging circuit, and LED light emitting diode, Q2, Q3 and battery E constitute a discharge circuit.Circuit for lamp was closed in charging when D8, R10 formed DC.ZD2 and Q3 form the discharge low-voltage protection circuit, and ZD1 and Q1 form the full electric protection circuit of charging.
When connecting the AC alternating current, after capacitor C 1 step-down, send D1, D2, D3, D4 rectification, one the tunnel charges to battery E through D6, one the tunnel makes it luminous through R2 charging indication diode (LED) 20, when the stay-supported switch connection, one the tunnel powers for LED1～LED19 through R7, D5, R8 makes it luminous, and LED1～LED19 does not work when the stay-supported switch disconnects.When battery was full of, the ZD1 conducting made the Q1 conducting through R5, reaches the effect of full electric protection.When the stay-supported switch connection, the emergent bright lamp that has a power failure, when the stay-supported switch disconnected, the lamp that do not work had a power failure.
When having a power failure, the stay-supported switch connection makes battery E power to LED1～LED19 through Q2, R8, makes it luminous; When the stay-supported switch disconnected, the negative pole of battery E and the negative line of LED1～LED19 disconnected, so not luminous.
Thereby easy to operate in the use of turning on light or turning off the light, simple in structure, long service life, energy-conservation.
