Technical field
This utility model relates to controlling bright light and turns off the light the technical field of circuit, automatically controls bright light particularly to a kind of novel light sensation and turns off the light circuit.
Background technology
In the illuminator of the band solar energy commonly used now, when illuminance height, system itself or need to manually turn off the light, maybe need to increase by a timing system to be allowed to extinguish, maybe need to increase sensor circuit to control to extinguish by sensing intensity of illumination, cause the waste of resource, virtually add cost.This utility model is not required to increase the peripheral circuit of too much very complicated, by utilizing the current characteristics of solar panel itself, use simple peripheral circuit in this utility model can meet illuminator in the case of daylight hours illuminance is enough, carries out the requirement of automatic distinguishing, if being also not required to carry out manual operation when it is subduing or intensity of illumination is not enough get final product and make illuminator automatically start work, while being greatly saved cost, energy-conserving and environment-protective are responded.
Therefore, how to realize a kind of circuit structure advantages of simple, can automatically control light-off of turning on light according to light conditions, while being greatly saved cost, the novel light sensation of energy-conserving and environment-protective automatically controls bright light circuit of turning off the light is technical problem the most urgently to be resolved hurrily.
Utility model content
Main purpose of the present utility model is to provide a kind of novel light sensation and automatically controls bright light and turn off the light circuit, aim at a kind of circuit structure advantages of simple, can automatically control light-off of turning on light according to light conditions, while being greatly saved cost, the novel light sensation of energy-conserving and environment-protective automatically controls bright light and turns off the light circuit.
The utility model proposes a kind of novel light sensation to automatically control bright light and turn off the light circuit, the lighting load feeder ear that the DC source Vbat that is connected with access interface including the access interface Solar IN of external solar energy acquisition device, lighting load drive circuit are connected with lighting load；Lighting load drive circuit includes the first resistance R1, the second resistance R2, drives audion Q1, the first diode D1, the second diode D2；When natural lighting degree is low, access interface Solar IN automatically controls to this light sensation that bright light circuit of turning off the light is inoperative, and lighting load is powered by DC source Vbat, and the first resistance R1 is the base resistance driving audion Q1, and the second resistance R2 is pull down resistor；When natural lighting degree meets condition, the high level of the access interface Solar IN input voltage more than DC source Vbat, first diode D1 conducting, DC source Vbat is charged simultaneously, second diode D2 is turned on by the first resistance R1, make to drive the base stage of audion Q1 and the pressure reduction of emitter stage less than its conducting voltage after first diode D1, the second diode D2 conducting, audion Q1 is driven to be in cut-off state, lighting load quits work, and now natural lighting degree has reached general lighting effect.
Utility model disclose a kind of be applied to carry in direct-current power lighting system circuit utilize natural lighting such as daylight to reach the novel circuit of energy-conserving action.When natural lighting degree is low, illuminator utilization carries DC source and is powered, and reaches illuminating effect；When natural lighting degree is sufficiently high, can automatically disconnect illuminator drive circuit, lighting circuit quits work, nature light is utilized to be illuminated, it is charged carrying DC source simultaneously, reach energy-saving effect, and, this light sensation automatically controls bright light circuit of turning off the light and is not required to increase too much peripheral circuit or IC can meet requirement.This utility model achieves a kind of circuit structure advantages of simple, can automatically control light-off of turning on light according to light conditions, and while being greatly saved cost, the novel light sensation of energy-conserving and environment-protective automatically controls bright light and turns off the light circuit.
Accompanying drawing explanation
Fig. 1 is that a kind of novel light sensation of this utility model automatically controls bright light and turns off the light the electric circuit construction schematic diagram of an embodiment of circuit.
The realization of this utility model purpose, functional characteristics and advantage will in conjunction with the embodiments, are described further referring to the drawings.
Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
With reference to Fig. 1, propose a kind of novel light sensation of the present utility model to automatically control bright light and turn off the light an embodiment of circuit, the lighting load feeder ear that the DC source Vbat that is connected with access interface including the access interface Solar IN of external solar energy acquisition device, lighting load drive circuit are connected with lighting load.Lighting load drive circuit includes the first resistance R1, the second resistance R2, drives audion Q1, the first diode D1, the second diode D2.
When natural lighting degree is low, access interface Solar IN automatically controls to this light sensation that bright light circuit of turning off the light is inoperative, and lighting load is powered by DC source Vbat, and the first resistance R1 is the base resistance driving audion Q1, and the second resistance R2 is pull down resistor.
When natural lighting degree meets certain condition, this condition is determined by solar energy acquisition device, the high level of the access interface Solar IN input voltage more than DC source Vbat, first diode D1 conducting, DC source Vbat is charged simultaneously, second diode D2 is turned on by the first resistance R1, make to drive the base stage of audion Q1 and the pressure reduction of emitter stage less than its conducting voltage after first diode D1, the second diode D2 conducting, audion Q1 is driven to be in cut-off state, lighting load quits work, and now natural lighting degree has reached general lighting effect.
In the illuminator of the band solar energy commonly used now, when illuminance height, system itself or need to manually turn off the light, maybe need to increase by a timing system to be allowed to extinguish, maybe need to increase sensor circuit to control to extinguish by sensing intensity of illumination, cause the waste of resource, virtually add cost.This utility model is not required to increase the peripheral circuit of too much very complicated, by utilizing the current characteristics of solar panel itself, use simple peripheral circuit in this utility model can meet illuminator in the case of daylight hours illuminance is enough, carries out the requirement of automatic distinguishing, if being also not required to carry out manual operation when it is subduing or intensity of illumination is not enough get final product and make illuminator automatically start work, while being greatly saved cost, energy-conserving and environment-protective are responded.The utility model discloses a kind of be applied to carry in direct-current power lighting system circuit utilize natural lighting such as daylight to reach the novel circuit of energy-conserving action.When natural lighting degree is low, illuminator utilization carries DC source and is powered, and reaches illuminating effect；When natural lighting degree is sufficiently high, can automatically disconnect illuminator drive circuit, lighting circuit quits work, nature light is utilized to be illuminated, it is charged carrying DC source simultaneously, reach energy-saving effect, and, this light sensation automatically controls bright light circuit of turning off the light and is not required to increase too much peripheral circuit or IC can meet requirement.This utility model achieves a kind of circuit structure advantages of simple, can automatically control light-off of turning on light according to light conditions, and while being greatly saved cost, the novel light sensation of energy-conserving and environment-protective automatically controls bright light and turns off the light circuit.
