Abstract
The utility model relates to an electric light source, which is provided with a spare power supply circuit which can automatically incorporate into the circuit of the electric light source when electric net is cut off. The circuit which is supplied power by an accumulator drives an inverter circuit to work and makes the electric light source go on luminous lighting by the signal emitting, receiving and magnifying, so the electric light source has an emergency function. The electric light source can also implement order control to lamps and lanterns by the switch of the electric light source. Besides, the spare power supply circuit is provided with an alarm circuit which monitors the output voltage of the accumulator, so the utility model can remind people to work well the job at hand in limited continued lighting time.
Description
The present invention relates to a kind of electric light source such as fluorescent lamp, incandescent lamp.
The power supply of electric light source is the alternating current of electrical network input, in case grid power blackout, electric light source just can lose illuminating effect.
The purpose of this invention is to provide a kind of electric light source that behind grid power blackout, still can continue luminous lighting.
The scheme that realizes the foregoing invention purpose is: overlap the stand-by power supply circuit of being made up of storage battery, vibration reflector, reception amplifier, control inverter and relay at electric light source Liang Duan And connection one.Wherein the charging device of storage battery connects with AC power circuit.Relay control AC power circuit is with the automatic conversion of stand-by power supply circuit and storage battery charge and discharge.Two leads of AC power circuit then are respectively the transmitting antenna of vibration reflector and the reception antenna of reception amplifier.
Further illustrate detailed content of the present invention below in conjunction with drawings and Examples.
Fig. 1: frame principle figure of the present invention;
Fig. 2: embodiment of the invention circuit theory diagrams.
Accompanying drawing is an example with the fluorescent lamp, has described the circuit structure of the electric light source of indication of the present invention, and is well-known, is provided with ballast (L in the daylight lamp circuit
5), starter (S) and switch (K
5) ， And is by switch (K
5) break-make of Control current.The present invention is at fluorescent lamp, be that (the stand-by power supply circuit that D) Liang Duan And connection one cover is made up of storage battery (E), vibration reflector, reception amplifier, control inverter and relay (J), wherein the charging device of storage battery (E) connects with AC power circuit electric light source.Relay (J) control AC power circuit is with the automatic conversion of stand-by power supply circuit and storage battery (E) charge and discharge, and two leads (A, B) of AC power circuit then are respectively the transmitting antenna of vibration reflector and the reception antenna of reception amplifier.
The vibration reflector comprises oscillating circuit and radiating circuit.The oscillating circuit of present embodiment is by IC555 time-base circuit, resistance R
1, R

4Reset under the effect of spring, one makes inversion coil (L
4) secondary coil form the loop.Two make storage battery (E) become discharge from charging.The reflector that vibrates on the other hand start working ， And and output high-frequency signal.Through the reception amplifier received signal.And makes triode BG after signal is amplified
2With triode BG
3And BG
4Difference set saturation condition and cut-off state.Inverter circuit promptly begins operate as normal.Electric light source (D) continues luminous lighting.At this moment, if switch (K
5) be in the position of pass, though the vibration reflector still in work, because of reception amplifier does not receive signal, inverter circuit is not just worked yet, electric light source (D) promptly is in the light-off state.
When power system restoration was transmitted electricity, relay (J) made electric light source (D) incorporate AC power circuit into, and storage battery (E) also enters charged state, and at this moment, a whole set of stand-by power supply circuit promptly quits work.
Because the power supply of stand-by power supply circuit is storage battery (E), therefore, the stand-by power supply circuit can only be kept the power supply of a period of time, note the electricity consumption situation of storage battery (E) for reminds people, the present invention is provided with the warning circuit that monitors storage battery (E) output voltage in the stand-by power supply circuit, warning circuit comprises voltage comparator circuit, oscillating circuit and alarm (P).The voltage comparator circuit of present embodiment is by triode BG

8Form with gun stocks 1/2IC, alarm (P) adopts the piezo of audible alarm or the light-emitting diode of light warning, when voltage comparator circuit obtains the voltage signal that needs warning, and triode BG
7Set cut-off state ， And by gun stocks 1/2IC output HIGH voltage through resistance R
13Turn-on transistor BG
8, alarm (P) promptly sends alarm signal according to the frequency of oscillating circuit.
Aforesaid electric light source.When grid power blackout, can continue luminous lighting and illumination is bright, possess emergency function; Utilize the electric light source switch, also can implement mandatory control light fixture; In addition, monitor the setting of the warning circuit of storage battery output voltage, the energy reminds people is promptly carried out work at hand in limited continuation lighting hours.
