Abstract
The utility model relates to a touch-tone time-delay slow-fade lamp, comprising a bulb. The touch-tone time-delay slow-fade lamp is characterized in that a control circuit thereof comprises an unidirectional SCR, a resistor, a capacitor, a first diode, a second diode and a switch; the anode of the unidirectional SCR is connected with the anode of a power supply by the bulb while the cathode of the unidirectional SCR is connected with the cathode of a power supply; a control grid of the unidirectional SCR is connected with the resistor; the other end of the resistor is connected with the anode of the capacitor; the anode of the capacitor is connected with the cathode of the first diode at the same time; the cathode of the capacitor is connected with the cathode of the power supply; one end of the switch is connected with the bulb while the other end is connected with the anode of the first diode; the anode of the second diode is connected with the cathode of the power supply; the cathode of the second diode is connected with the anode of the first diode. The control circuit of the touch-tone time-delay slow-fade lamp is suitable for manufacturing bed-lamps.
Description
Technical field
The utility model relates to a kind of lights, specifically, relates to a kind of button gradually concealed light of delaying time.
Background technology
At present, the incandescent lamp that the lights great majority all are to use, all be to extinguish moment when lamp is closed, allow people's eyes very uncomfortable like this, particularly be used in the lamp of the head of a bed, realize the time-delay deepening of lamp, will make eye have one and adapt to dark process, make the people have a more comfortable sleep, therefore, just need a kind of time-delay gradually concealed light satisfy the needs of this bedside lamp.
The utility model content
The problem that the utility model solved provides a kind of button gradually concealed light of delaying time, and realizes the function that the time-delay deepening was closed at last when bedside lamp cut out.
To achieve these goals, the utility model provides a kind of button gradually concealed light of delaying time, button is delayed time gradually, and the control circuit of concealed light comprises one-way SCR, resistance, electric capacity, first diode, second diode, switch, the anode of one-way SCR links to each other with positive source by bulb, negative electrode links to each other with power cathode, the control utmost point of one-way SCR is connected with the negative pole of first diode, the negative pole of first diode also is connected with the positive pole of electric capacity, the negative pole of electric capacity links to each other with power cathode, switch one end links to each other with bulb, the other end links to each other with the positive pole of first diode and the negative pole of second diode, and the positive pole of second diode links to each other with the negative pole of electric capacity.
Behind the switch closure, one-way SCR and diode wheel conductance are logical, and the conducting that the storage voltage on the electric capacity is kept through conductive discharge is simultaneously because of being disconnected, so it is luminous darker to be in the bulb of half-wave power supply state.After capacitor discharge finished, one-way SCR turn-offed bulb when the alternating current zero passage.In this control circuit, the time of the time-delay of turning off the light, resistance can be selected variable resistor for use, thereby changes the delay time of turning off the light, to adapt to various needs by resistance and electric capacity decision; Simultaneously, one-way SCR to adapt to the visual needs of people, has also been saved the energy in brightness half of brightness when turning on light only of turning off the light between time delay.
After below in conjunction with accompanying drawing, embodiment the utility model being described in detail, other characteristics of the present utility model, advantage will be more obvious.
Description of drawings
Accompanying drawing is a circuit structure diagram of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As accompanying drawing, the anode of unidirectional controllable silicon S CR links to each other with positive source by bulb L, negative electrode links to each other with power cathode, the control utmost point of unidirectional controllable silicon S CR is connected with resistance R, the other end of resistance R is connected with the positive pole of capacitor C, the anodal of capacitor C is connected with the negative pole of the first diode D1 simultaneously, the negative pole of capacitor C links to each other with power cathode, switch SW one end links to each other with bulb L, the other end links to each other with the positive pole of the first diode D1, the positive pole of the second diode D2 links to each other with power cathode, and the negative pole of the second diode D2 links to each other with the positive pole of the first diode D1.
Unidirectional controllable silicon S CR uses the controllable silicon of MCR100-6 model, and the first diode D1 and the second diode D2 use 1N4007 model diode.
Connect each electric elements by accompanying drawing.Circuit connect finish after, Closing Switch SW, the unidirectional controllable silicon S CR and the first diode D1 take turns conducting, bulb L normally lights, capacitor C begins charging simultaneously; After switch SW disconnects, stored voltage begins discharge on the capacitor C, and CR provides trigger voltage for unidirectional controllable silicon S, keeps the conducting of unidirectional controllable silicon S CR, but because the second diode D2 is disconnected, so bulb L is in the half-wave power supply state, luminous darker, in the capacitor C discharge off, unidirectional controllable silicon S CR can not get trigger voltage, quit work, bulb L is disconnected, and bulb L extinguishes.When switch was opened once more, circuit began to repeat above-mentioned work.In whole switch turn off process, the brightness of bulb is about half of its normal operating conditions, about 30 seconds of bulb fall time, both saved the energy, and realized the gradually dark function of time-delay again, satisfied the visual needs of people.
