Description
Technical field
The invention belongs to illumination brightness adjustment control field, particularly electronic circuit and singlechip technology.
Background technology
Current Single switch light modulating device can not increase continuously and reduce light-source brightness; Light source delay-action, power cutoff can not be controlled.
Summary of the invention
The present invention seeks to Single switch light modulating device increase continuously and reduce light-source brightness; Control light source delay-action, power cutoff.
Structure of the present invention is made up of operating unit and control unit, and operating unit side is connected with electric main; Operating unit opposite side is connected with control unit input; Control unit output is connected with conversion electric power; Conversion electric power output is connected with light source.The output end signal change of control unit, the change of light source luminescent brightness correspondence.
Conversion electric power is that full-wave rectification capacitor filtering is powered, and short time half-wave is powered, and conversion electric power still can driving light source luminescence.
Control method of the present invention is: control unit input end signal transfers half-wave voltage signal to by exchanging all-view signal, and control unit output dimming control signal is brightness decrement states at any time; Control unit output control signal is delayed shutoff light source luminescent state; Operating unit switch in parallel diode.
Accompanying drawing explanation
Fig. 1 is lamp control device structural representation of the present invention.
Fig. 2 is operating unit structural representation of the present invention.
Embodiment
Embodiment 1, continuous light tuning lamp control device of the present invention.Fig. 1 is continuous light tuning lamp control device structural representation of the present invention, is made up of operating unit and control unit.Operating unit comprises K switch and diode D, the interconnected diode D of K switch.Control unit comprises half-wave time delayed turn-off controller and light adjusting controller.
When powering initial, K switch disconnects, and the control unit input half-wave that prior art is formed is powered, and control unit output power supply signal is not power supply state, and output dimming control signal makes light source non-light emitting state.
K switch conducting, control unit input all-wave is powered, and control unit output power supply signal is all-wave power supply state; Output dimming control signal light source luminescent brightness is changed in time progressively increase state.When light-source brightness change reaches requirement, instantaneous (being less than 1 second) shutdown switch K, at this moment half-wave is powered and is made light source luminescent, turn on-switch K, and output dimming control signal makes light source luminescent brightness invariant state.Again increase light-source brightness, instantaneous shutdown switch K, turn on-switch K.
K switch is connected, and control unit output power supply signal is all-wave power supply state; Control unit output dimming control signal makes light source luminescent invariant state.Shutdown switch K, control unit input half-wave is powered; Control unit output power supply signal is that half-wave is powered time delayed turn-off state; Control unit output dimming control signal makes the bright decrement states in time of light source luminescent.When light-source brightness change reaches requirement, it is make light source luminescent brightness invariant state that turn on-switch K output controls dim signal.Again reduce light-source brightness, aforesaid operations can be repeated to minimum luminosity.
After K switch is connected, long-time shutdown switch K, control unit output dimming control signal makes light source luminescent brightness decrement states in time, is decremented to minimum value and remains unchanged, and after between delay timing, output dimming control signal turns off light source luminescent state.Shutdown switch K can Delayed extinguishing.
After K switch is connected, long-time shutdown switch K, control unit output power supply signal is that half-wave is powered time delayed turn-off state, and delay time is greater than light-source brightness decimal reduction time, and after time delay to setting-up time, control unit output power supply signal is the state of stopping power supply.Shutdown switch K, can Delayed extinguishing, power cutoff.
In sum, control method of the present invention is: control unit input end signal transfers half-wave voltage signal to by exchanging all-view signal, and control unit output dimming control signal is brightness decrement states at any time; Control unit output control signal is delayed shutoff light source luminescent state; Operating unit switch in parallel diode.
Embodiment 2, incremental dimming lamp control device of the present invention.Embodiment 1 control unit output consecutive variations dimming control signal is exported, changes changed in stages dimming control signal into and export; Remainder is identical with embodiment 1.A K switch instantaneous shutoff control unit output dim signal output state change once.K switch transfers shutoff to by conducting, and control unit output control signal is delayed shutoff light source luminescent state.
