Abstract
The utility model discloses the multi-functional speed governing light modulation electronic switch who constitutes is in the same place electric fan speed governing, electric light adjust luminance, supply socket and power indicator. The speed regulation of the electric fan is realized by electrically connecting a potentiometer, a switch, a capacitor, a resistor, a bidirectional diode and a bidirectional thyristor in an insulating shell; the light regulation of the electric lamp is realized by connecting a rectifier diode and a switch in parallel with a speed regulation circuit; the light emitting diode and the current limiting resistor are connected in parallel with the speed regulating circuit to realize power supply finger type; and also has a socket function. Can be installed in a hidden way like a wall switch, and is suitable for a family with a switch which controls the speed regulation of an electric fan and adjusts the light of an electric lamp.
Description
The utility model be a kind of have electric fan speed governing, electric light light modulation, supply socket and night deixis the light-adjusting and speed-adjusting device.
Electric fan speed-regulating switch known today is made of transformer, speed-regulating switch knob, and this speed-regulating switch is inserted in the electric fan circuit, and the turn knob is the scalable fan speed just.Because the idle power consumption of transformer makes the speed-regulating switch heating, the power consumption of speed-regulating switch itself accounts for 5% of electric fan power consumption, and volume can not be installed as wall switch implicit expression greatly.
The purpose of this utility model provide a kind of can speed governing the multifunctional electronic switch of light modulation simultaneously again, can install as wall switch, can not only realize the stepless speed regulation of electric fan, and can reduce the power consumption of switch itself, and realize light modulation simultaneously, power supply indication at night and function of socket.
The new purpose of this practicality is achieved in that in insulation crust, potentiometer, switch, electric capacity, resistance, bidirectional diode, the bidirectional triode thyristor basic alignment circuit that is electrically connected to form; Light-emitting diode, current-limiting resistance are parallel to alignment circuit; Socket one end is connected with live wire, the other end is connected with ground wire, and dimmer switch and rectifier diode are parallel to alignment circuit.When speed-regulating switch was opened, supply voltage charged to electric capacity through resistance, potentiometer, and the pipe conducting to the bidirectional triode thyristor control utmost point one trigger voltage, makes the bidirectional triode thyristor triggering and conducting when the electric capacity both end voltage rises to blocking voltage greater than bidirectional diode; The The Trigger of Bidirectional Triode Thyristor angle is by the decision of the charge constant of electric capacity, the numerical value that changes potentiometer has just changed the capacitor charging time constant, also just changed the The Trigger of Bidirectional Triode Thyristor angle, so just changed the electric current that flows through the load electric fan, so, make the magnitude of voltage at electric fan two ends change, thereby the speed of electric fan change along with the change of potentiometer value.Light modulation is to utilize the halfwave rectifier of diode to realize, when dimmer switch during directly with power connection, light is the brightest, and when dimmer switch and diode connection, the voltage of electric light is half-wave voltage, and the brightness of electric light has only half of normal brightness.
Owing to adopt such scheme to carry out speed governing, reduced the power consumption of speed-regulating switch itself, also realized electric light light modulation, power supply indication and function of socket simultaneously.
