Description
Technical field
The present invention relates to lamp control device field, particularly, relate to a kind of Light Control Unit.
Background technology
Lamp is one of necessity in people's daily life, and in classroom, in office, it adopts incandescent lamp, electricity-saving lamp etc. mostly, and utilizes Switch Controller lamp to control.Enter the classroom or office in the morning one, habitually opened by lamp, and along with the grow of light, lamp still by original brightness light yellow, and when walking out this place, is somebody's turn to do because light was brighter, people not too can remove to note lamp whether light yellow and directly going away, and this just causes the waste of the energy.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Light Control Unit, and it can whether someone monitors in space, and regulates lamp brightness according to light intensity, nobody time time delay turn off the light, energy savings.
The present invention's adopted technical scheme that solves the problem is:
A kind of Light Control Unit, comprises bridge rectifier and is connected to the lamp of bridge rectifier input, and an output of described bridge rectifier to be held with silicon controlled A by human induction switch and is connected, and another input is connected on silicon controlled K end; Described silicon controlled A is held and to be connected with the drain electrode of transistor by the first resistance and K hold and is connected respectively by the source electrode of the 4th resistance, electric capacity and transistor, grid, and described silicon controlled G holds and is connected on the source electrode of transistor; The second resistance and photo resistance that are in series is connected with between the drain and gate of described transistor.
As preferably, described human induction switch is human body infrared sensing switch.
Further, described human body infrared inductive switch is TDL-2181R.
As preferably, the resistance of the 4th described resistance is less than one kilohm.
As preferably, described photo resistance is GL5616.
To sum up, the invention has the beneficial effects as follows:
1, the present invention utilizes the switch of human induction switch to lamp to control, and utilize the intensity of photo resistance to light to respond to, silicon controlled ON time is regulated, thus control the brightness of lamp, reach and regulate according to the brightness of light intensity to lamp, nobody time time delay turn off the light, energy savings.
2, circuit structure of the present invention is simple, is easy to realize, economical and practical.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the present invention's do, but embodiments of the present invention are not limited thereto.
Embodiment 1:
A kind of Light Control Unit as shown in Figure 1, comprise bridge rectifier and the lamp L being connected to bridge rectifier input, one output of described bridge rectifier is held with the A of controllable silicon VS by human induction switch S and is connected, and another input is connected on the K end of controllable silicon VS; The A end of described controllable silicon VS to be connected with the drain electrode of transistor T by the first resistance R1 and K hold and is connected respectively by the source electrode of the 4th resistance R4, electric capacity C and transistor T, grid, and the G of described controllable silicon VS holds and is connected on the source electrode of transistor T; The the second resistance R2 be in series and photo resistance R3 is connected with between the drain and gate of described crystal T pipe.
As shown in Figure 1, bridge rectifier is made up of diode D1-D4.The prerequisite of whole circuit working be the shutoff of human induction switch whether.When human induction switch S has monitored people, human induction switch S connects, civil power is after bridge rectifier rectification, and the voltage be added between the A end of controllable silicon VS and K end is a pulse voltage, supplies follow-up circuits for triggering as DC power supply and synchronizing voltage after resistance R1 step-down.In every half period, when the charging voltage on electric capacity C repeatedly arrives the peak point voltage of transistor, transistor turns, electric capacity C is by the 4th conductive discharge, now, the 4th resistance exports a pulse, delivers to silicon controlled G and hold, trigger controlled silicon conducting, now, lamp is shinny; After controlled silicon conducting, hold the pressure drop between G end very little at silicon controlled A, now, circuits for triggering quit work.When supply voltage zero passage, controllable silicon turns off, until next cycle starts, electric capacity charges again, successively said process repeatedly.In circuits for triggering circuit, the photo resistance that employing is in series and the second resistance regulate the ON time of controllable silicon in every half period, thus control the brightness of lamp.Second resistance is to its protective effect of circuits for triggering.When the resistance of photo resistance is large, namely photo resistance and the second resistant series gained resistance value are greatly, and the electric capacity needs longer charging interval could by controlled silicon conducting, and now, bulb is darker; Otherwise bulb is brighter.When human induction switch S monitors nobody, human induction switch S time delay disconnects, and after disconnection, subsequent conditioning circuit does not then work, and lamp does not work, and reaches the object of saves energy.
Embodiment 2:
A kind of Light Control Unit as shown in Figure 1, the present embodiment is optimized on the basis of above-described embodiment, and namely described human induction switch is human body infrared sensing switch.Human induction switch have based on microwave sensor, have based on infrared inductor.And based on microwave sensor, when unmanned or people's transfixion, namely human induction switch disconnects, in self-study classroom or library, obviously inapplicable.Adopt the human body infrared inductive switch based on infrared inductor, it can directly be monitored people, and no matter whether people is walking about, and it is widely applicable.
In order to improve the sensitivity of human body infrared inductive switch, described human body infrared inductive switch is TDL-2181R.
The effect of the 4th resistance is mainly G end trigger impulse being sent into transistor, and trigger controlled silicon conducting, its resistance is not easily excessive, and time excessive, its power consumed is also large, therefore the resistance of the 4th described resistance is less than one kilohm.
Described photo resistance is GL5616.Photo resistance is the very important factor of automatic light adjuster, and its performance is directly connected to the susceptibility of automatic light adjuster to light.GL5616, it is highly sensitive, spectral response is high, effectively can improve the sensitivity of whole automatic light adjuster.
As mentioned above, the present invention can be realized preferably.
