Below, the action of the circuit of form of implementation 1 of the present invention is described according to Fig. 1.In Fig. 1, when connecting DC power supply 1, as the force-feeling sensor who is located at output control circuit OC10 detects nobody and exists, and then its output becomes low level.Be output as low level occasion at OC10, the current collection of transistor 34 is high level very, and the collector electrode of transistor 33 becomes low level.That is, commutation circuit SW10 is output as low level, so the grid of MOSFET3 and capacitor 16 also become low level with the current potential of the tie point of resistance 12, and inverter circuit fail to start vibration, discharge lamp 6 is the light-off state.
As the force-feeling sensor who is located at output control circuit detects the people and exists, and then its output becomes high level.Be output as the occasion of high level at OC10, the current collection of transistor 34 is low level very, and the collector electrode of resistance 33 becomes high level, and commutation circuit SW10 is output as high level, so the grid of MOSFET3 and capacitor 16 also become high level with the current potential of the tie point of resistance 12.As become this state, and then in capacitor 16, charging current flows to capacitor 16 from the positive pole of DC power supply 1 by the filament of resistance 11, choking-winding 5, discharge lamp 6, the path of resistance 12, and its voltage rises along with effluxion.
Reach the puncture voltage of diac 17 as the voltage of capacitor 16, then be charged to of the path discharge of the electric charge of capacitor 16 by diac 17, resistance 18,13,2 coil 5b of resistance, the voltage that results from resistance 13 and 2 coil 5b this moment is added to the grid of MOSFET3, so, the MOSFET3 conducting.As the MOSFET3 conducting, then be charged to of the path discharge of the electric charge of capacitor 7 and coupling capacitor 8 by choking-winding 5, MOSFET3 by resistance 11, make the further conducting of MOSFET3 by the voltage that results from choking-winding 5 by this discharging current, MOSFET2 ends.
After the cycle of being determined by the choking-winding 5 of discharge lamp load circuit L10, capacitor 7, coupling capacitor 8, the electric current of choking-winding 5 is anti-phase, so, make the MOSFET2 conducting by the effect of 2 coil 5a, 5b, MOSFET3 is ended.After, MOSFET2 and MOSFET3 be conduction and cut-off alternately, discharge lamp 6 bright lamps.Then, output as output control circuit OC10 under the state of discharge lamp 6 bright lamps becomes low level (people does not exist) once more, then the output of commutation circuit SW10 becomes low level, the grid of MOSFET3 and capacitor 16 also become low level with the current potential of the tie point of resistance 12, inverter circuit can not vibrate, and discharge lamp 6 becomes the light-off state.That is, have the force-feeling sensor as output control circuit OC10 and detect the people at this state, then discharge lamp 6 bright lamps do not exist as the people, and then discharge lamp 6 becomes the light-off state.
As output control circuit, be not limited to have force-feeling sensor's circuit, as have clock circuit, for example become high level output in the scope of falling the moment of sunrise from day, then discharge lamp 6 can be turned off the light and set like that in the bright lamp of sunset, sunrise.
In addition, as output control circuit OC10 is provided with timing circuit, for example by after energized 1 hour during the lamp of output high level be suitable for for the reading lamp of bed is set, even, also can after 1 hour, automatically turn off the light then having forgotten the occasion of turning off the light.
As described above according to form of implementation 1 of the present invention, with from having force-feeling sensor, clock circuit, and the pettiness output Control current interlock of the output control circuit of timing circuit etc., directly do not make the circuit part on/off that flows out big principal current from DC power supply, can make the electric power on/off of discharge lamp load circuit by little Control current, can carry out bright lamp, the light-off of discharge lamp, can be cheap, small-sized, energy-conservation.
In addition, the people the bright lamp of occasion, as not existing, it is energy-conservation then to turn off the light, and can make its cheapness, small-sized.
