Abstract
The invention provides a progressive brightening lamp control device. The circuit of the progressive brightening lamp control device comprises a switch S1, an NPN triode Q1, an NPN triode Q2, a relay RL1, a relay RL2, a resistor R1, a resistor R2, a capacitor C1, a diode D1, a diode D2 and a diode D3, wherein the two relays constitute a switch to be serially connected with a lighting loop; when the switch S1 is closed just now, the relay RL2 pulls in while the relay RL1 is still in the released state, at the moment, the lighting loop is connected in series with the diode D3, and a lighting lamp is relatively dark; after about ten minutes, the relay RL1 pulls in to enable an alternative switch S2 to be switched to the normally-open side, at the moment, the lighting loop is separated from the diode D3, the lighting lamp returns to the normal brightness, and therefore, progressive brightening is realized. The transition not only realizes excellent night illumination but also can reduce irritation, caused by instant bright light at night, of human eyes, so that comfort and convenience are brought for people accustomed to getting up in the night to urinate.
Description
Technical field
The present invention relates to a kind of light controller automatically brightened step by step, belong to application electric technology field.
Background technology
In actual life, many people often have the experience of standing up midnight to visit the restroom, and because night is comparatively dark, the bright eyes of people of will giving of moment lamp cause strong impulse, allow people feel quite uncomfortable.Therefore, be necessary to design a kind of light controller, when realizing opening lighting switch, the brightness of lamp starts relatively dark, after about time delay in ten seconds, waits after human eye adapts to night-environment substantially, illuminating lamp is allowed to be transformed into normal brightness again, like this excessively both can realize good night illumination, the stimulation that night, instantaneous strong light caused human eye can being weakened again, can bringing comfortable and convenient to having the people of custom of getting up in the night to urinate.
Summary of the invention
The object of this invention is to provide a kind of light controller brightened step by step, during to realize turning on light night, the brightness of lamp can brighten step by step, allows human eye have a process adapting to night-environment, to a kind of more comfortable sensation of people.
The concrete technical scheme that the present invention takes is as follows:
A kind of light controller brightened step by step, it is characterized in that: the circuit of this device comprises switch S 1, NPN triode Q1 and Q2, relay R L1 and RL2, resistance R1 and R2, electric capacity C1, diode D1, D2 and D3, wherein one end of resistance R1 with R2, the negative pole of diode D1 with D2, relay R L1 are connected+5V power supply through switch S 1 after being all connected in parallel with one end of the coil of RL2 again; The other end of resistance R1 is connected the base stage of triode Q1 jointly with the positive pole of electric capacity C1, the negative pole of electric capacity C1 and the grounded emitter of triode Q1, and the positive pole of diode D1 is connected the collector electrode of triode Q1 jointly with the other end of the coil of relay R L1; The other end of resistance R2 connects the base stage of triode Q2, the grounded emitter of triode Q2, and the positive pole of diode D2 is connected the collector electrode of triode Q2 jointly with the other end of the coil of relay R L2; One group of normally-open normally-close contact of relay R L1 forms an either-or switch S2, one group of normally opened contact of relay R L2 forms another switch S 3, the fixed contact of either-or switch S2 is as an output of this device, the normally closed moving contact of either-or switch S2 connects the negative pole of diode D3, the fixed contact often starting connecting valve S3 after contact shunt of the positive pole of diode D3 and either-or switch S2, the moving contact of switch S 3 is as another output of this device.
Beneficial effect of the present invention is: by two output series connection access lighting loops when this light controller brightened step by step uses, when switch closes, the brightness of lamp starts relatively dark, after about time delay in ten seconds, after human eye adapts to night-environment substantially, just allow illuminating lamp be transformed into normal brightness, so excessively both can realize good night illumination, the stimulation that night, instantaneous strong light caused human eye can being weakened again, can bringing comfortable and convenient to having the people of custom of getting up in the night to urinate.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of the light controller that this brightens step by step.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, this circuit of light controller brightened step by step comprises switch S 1, NPN triode Q1 and Q2, relay R L1 and RL2, resistance R1 and R2, electric capacity C1, diode D1, D2 and D3, and wherein one end of resistance R1 with R2, the negative pole of diode D1 with D2, relay R L1 are connected+5V power supply through switch S 1 after being all connected in parallel with one end of the coil of RL2 again; The other end of resistance R1 is connected the base stage of triode Q1 jointly with the positive pole of electric capacity C1, the negative pole of electric capacity C1 and the grounded emitter of triode Q1, and the positive pole of diode D1 is connected the collector electrode of triode Q1 jointly with the other end of the coil of relay R L1; The other end of resistance R2 connects the base stage of triode Q2, the grounded emitter of triode Q2, and the positive pole of diode D2 is connected the collector electrode of triode Q2 jointly with the other end of the coil of relay R L2; One group of normally-open normally-close contact of relay R L1 forms an either-or switch S2, one group of normally opened contact of relay R L2 forms another switch S 3, the fixed contact of either-or switch S2 is as an output of this device, the normally closed moving contact of either-or switch S2 connects the negative pole of diode D3, the fixed contact often starting connecting valve S3 after contact shunt of the positive pole of diode D3 and either-or switch S2, the moving contact of switch S 3 is as another output of this device.
By in two output series connection access lighting loops when this light controller brightened step by step uses, when switch S 1 is just closed, the rapid conducting of triode Q2, relay R L2 adhesive, and now triode Q1 still ends, relay R L1 is still in release condition, now lighting loop is serially connected with diode D3, illuminating lamp is relatively dark, after about time delay in ten seconds, + 5V power supply reaches certain voltage through resistance R1 to electric capacity C1 charging, triode Q1 starts conducting, relay R L1 adhesive, either-or switch S2 is made to switch to side of often making war, now lighting loop is not containing diode D3, illuminating lamp recovers normal brightness, realize the process brightened step by step thus.
