Description
Technical field
The utility model relates to the illuminating lamp control circuit, particularly, relates to infrared light control mating type lighting circuit.
Background technology
Indoor light relates to public places such as each family and classroom; In most of the cases; An indoor daylighting part derives from indoor light; Another part derives from the outdoor natural light line, and when the outdoor natural light line was inadequate, people opened indoor light so that indoor light intensity is enough bright.
The weak point of prior art is that the brightness of indoor light is certain, can't be suitable for outdoor light automatically and make indoor light replenish the deficiency of outdoor light just, thereby cause waste of electric energy.
The utility model content
To defective of the prior art, the purpose of the utility model provides a kind of infrared light control mating type lighting circuit.
An aspect according to the utility model; Infrared light control mating type lighting circuit is provided; It is characterized in that; Comprise full bridge rectifier; Wherein, be in series with illuminating lamp, switch and power supply between the interchange input of said full bridge rectifier, the output, be in series with pyroelectric infrared sensor, photo resistance and second resistance successively between the direct current input of said full bridge rectifier, the output; One end of the disconnected said photo resistance of said second resistance is connected with first resistance; One end of disconnected said second resistance of said first resistance is connected with the anode of bidirectional thyristor, and the negative electrode of said bidirectional thyristor is connected to the node of said photo resistance and said pyroelectric infrared sensor, and the node of said photo resistance and said second resistance is connected to the positive pole of diode; Be connected with bidirectional trigger diode between the negative pole of said diode and the control end of said bidirectional thyristor, the negative pole of said diode is connected with said pyroelectric infrared sensor between the end of said photo resistance and is connected with electric capacity.
Preferably, said pyroelectric infrared sensor is provided with Fresnel lens.
Preferably, be provided with shadow shield between said photo resistance and the said illuminating lamp.
The utility model comprises photo resistance, pyroelectric infrared sensor, electric capacity, IGCT, illuminating lamp and several resistance etc.By day, cause that when ambient light dies down the resistance of photo resistance increases, the dividing potential drop that is added on the electric capacity is risen, and then the angle of flow of IGCT is increased, reach the purpose that increases the illuminating lamp voltage.Otherwise if light on every side brightens, then the resistance of photo resistance descends, and causes the angle of flow of IGCT to diminish, and the illuminating lamp voltage also descends simultaneously, makes the light deepening, thereby realizes the control to lamp illuminance.Simultaneously, be connected to a pyroelectric infrared sensor on the main line of circuit.When indoor man-hour is arranged,, accepted identification back circuit by pyroelectric infrared sensor and connect automatically, otherwise circuit turn-offs because the people knows from experience the specific infrared wavelength of emitting about 9 ~ 10um.For the convenience of the users, also added a hand switch in the circuit, special circumstances when watching lantern slide (as) but manual-lock.
Comparing (like light commutation circuit, acousto-optic control circuit etc.) with existing other circuit compares; The circuit that provides according to the utility model can not only come on-off circuit according to the specific ultrared wavelength that the people emitted; Avoided the situation of various erroneous judgements; Simultaneously also can be according to the bright brightness of secretly regulating lamp of lamp, saves energy.
