The utility model content

The purpose of this utility model is to overcome above-mentioned technical deficiency, a kind of classroom illumination electricity-saving controller is provided, this classroom illumination electricity-saving controller is when light reaches certain illumination, electric light is closed automatically, just allow the illumination of turning on light when having only light to drop to a certain degree, that avoids daytime opens the altar lamp phenomenon.This classroom illumination electricity-saving controller serviceability is stable, and practice effect is good, and is energy-conservation obvious, can use in awareness of saving energy relatively poor all kinds of classroom or other corresponding places.

For reaching the foregoing invention purpose, the technical scheme that is adopted is: a kind of classroom illumination electricity-saving controller is characterized in that: comprise power circuit, time-base circuit and control circuit; Described power circuit comprises transformer, relay, bridge heap and capacitor; Described transformer input termination civil power, output cross structure heap, the transformer input also is parallel with illuminating lamp and the relay normally open switch that is cascaded; Described control circuit comprises resistor, capacitor, four triodes and relay, and described relay and triode are in series, and power circuit connects triode by the homing position type push-button switch; Described time-base circuit one end connects power circuit, and the other end connects control circuit; Described controller also is provided with the illuminance collection sensor devices that the power supply that is installed on the casing outer surface is indicated the potentiometer of electroluminescent lamp, band spinner and is installed in the position that light can not directly shine in the classroom.

According to classroom illumination electricity-saving controller provided by the utility model, it is characterized in that: also be provided with the capacitor that can prevent the external world and electrical network noise jamming.

According to classroom illumination electricity-saving controller provided by the utility model, it is characterized in that: also be provided with can change illuminating lamp by bright to putting out by the delay degree resistor that puts out in the bright process.

The classroom illumination electricity-saving controller that the utility model provides is when light reaches certain illumination, and electric light is closed automatically, just allows the illumination of turning on light when having only light to drop to a certain degree, and that avoids daytime opens the altar lamp phenomenon.This product is used and is shown, overcast and rainy illuminance does not influence the illumination of turning on light when low.This classroom illumination electricity-saving controller serviceability is stable, and practice effect is good, and is energy-conservation obvious, can use in awareness of saving energy relatively poor all kinds of classroom or other corresponding places.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

A kind of classroom illumination electricity-saving controller is characterized in that: comprise power circuit, time-base circuit and control circuit; Described power circuit comprises transformer, relay, bridge heap and capacitor; Described transformer input termination civil power, output cross structure heap, the transformer input also is parallel with illuminating lamp and the relay normally open switch that is cascaded; Described control circuit comprises resistor, capacitor, four triodes and relay, and described relay and triode are in series, and power circuit connects triode by the homing position type push-button switch; Described time-base circuit one end connects power circuit, and the other end connects control circuit; Described controller also is provided with the illuminance collection sensor devices that the power supply that is installed on the casing outer surface is indicated the potentiometer of electroluminescent lamp, band spinner and is installed in the position that light can not directly shine in the classroom.The classroom illumination electricity-saving controller also be provided with the capacitor that can prevent the external world and electrical network noise jamming and can change illuminating lamp by bright to putting out by the delay degree resistor that puts out in the bright process.

Fig. 1 is the circuit theory diagrams of the classroom illumination electricity-saving controller that provides of the utility model.As shown in FIG., civil power is through transformer T step-down, and after bridge heap IC1 rectification, the C1 filtering, the direct voltage of output 12V, D1 are power supply indication electroluminescent lamp.Power supply adds to 2,6 pin of time-base circuit IC2 after D2, R2, R3 dividing potential drop.When ambient light when dying down by force, the internal resistance of D2 is changed from small to big, when 2, the 6 pin voltages of IC2 drop to 1/3Vcc, the output state counter-rotating of IC2,3 pin output high level, V1, V2 saturation conduction, late-class circuit gets, D4 is luminous, indicates the illumination that allows to turn on light, and can click this moment to touch to decontrol to close to open electric light; When the moment of pressing N1, power supply adds to the V3 base stage through R8, N1, V3, V4 saturation conduction, and relay J gets electric adhesive, the J-K closure, its contacting lighting lamp power loop, classroom lamp L is bright; Simultaneously, the voltage of V4 collector electrode feeds back to the base stage of V3 after R10, relay D.C. resistance Rj dividing potential drop, make V3, V4 keep conducting, and J is able to self-insurance, the still closed lighting lamp circuit of connecting of relay contact.Press N2 in the time of need turning off the light, V3 base stage shorted to earth, V3, V4 end, and J discharges, and J-K disconnects, and cuts off lighting lamp power.

When ambient light changes from weak to strong, the internal resistance of D2 from large to small, when 2, the 6 pin voltages of IC1 rise to 2/3Vcc, 3 pin output low levels, V1, V2 end, the late-class circuit dead electricity, J discharges, the J-K open circuit is closed the illuminating lamp in the classroom automatically.Because the capacity of C2 is bigger, make in the time of can preventing the instantaneous strong illumination D2 at night that electric light extinguishes in the classroom in, C3 can prevent the external world and electrical network noise jamming, the reliability of raising circuit; The adding of R5, R6 can change illuminating lamp, and this resistance is more little to putting out by the delay degree of putting out in the bright process by bright, and the hysteresis journey is also just more little.

Install and note: D2 is the sensor devices that illuminance is gathered, and D2 should be installed in the place that light can not directly shine in the classroom, to gather natural daylight illumination; N1, N2 adopt the homing position type push-button switch; D1, D4 should be installed on the more eye-catching position of casing, so that eye sight line is observed its operating state.

Debugging: when illuminance in the classroom does not need to turn on light illumination (about illuminance 200Lx), adjust R2 from bottom to top, J is just discharged, D4 extinguishes; When illumination in the classroom drops to need turn on light illumination (about 150Lx) time, adjust R6 from bottom to top, make D4 luminous, adjust the set point that can influence R2 behind the R6, need to adjust once more.R2, R6 adopt the potentiometer of band spinner.Factory's large-scale production can utilize the illuminance meter adjustment.
