Abstract

The utility model discloses a light changeable energy-saving pull switch. The exiting duplex pull switch is used as the foundation, and a semiconductor diode is connected between the two wire-outlet ends of the light changeable energy-saving pull switch. The full wave of the alternating current is changed into half wave through the characteristic of the semiconductor, and the purposes of voltage reduction and light change can be achieved. The light changeable energy-saving pull switch is especially suitable for the household to use at different times and occasions with different lights, and the light changeable energy-saving pull switch saves the energy after changing the light simultaneously. The utility model has the advantages of long service life and low cost.

Description

Light changeable energy-saving pullswitch

The utility model relates to a kind of pulling switch.

Present commercially available pulling switch, be divided into simply connected, duplex, multi-joint several, its operation principle all is that the central authorities of switch are provided with a rotatable contact, the metal contact of several block gaps is set around this contact, each metal contact all links to each other with lead-in wire terminal, and even on each leading-out terminal of switch be furnished with a coupled fixation spring tab, and the termination of shell fragment is positioned on the position of metal contact, utilize the elastic force of this shell fragment that shell fragment is closely contacted with the metal contact, finish the connection work of switch.Spur rotary contact with backguy, this contact is with regard to sound of laughing a rotation, finish logical one disconnected one logical switch work successively, constantly circulation, the major defect of this switch is: function singleness, can only finish logical one disconnected work, can not control the brightness of bulb, be not easy to use in the place of two kinds of brightness of needs.

The purpose of this utility model provides a kind of novel light adjustable power saving pulling switch that changes the bulb brightness of illumination.

For achieving the above object, the utility model adopts a duplex pulling switch, connects a semiconductor diode between two leading-out terminals of this switch, utilizes semi-conductive characteristic, and the all-wave of alternating current is become half-wave, plays the effect of step-down.Be used alternatingly two leading-out terminals of switch, just can reach the purpose that changes bulb brightness.The brightness of bulb has reduced, and natural energy consumption is just low.

The single phase alternating current (A.C.) voltage of China is 220 volts, and single power of bulb of general family can be greater than 200 watts.Experimental result shows, becomes that the power of bulb is about 60 watts behind the light this moment, so the ac resistance of the used semiconductor diode of switch presses and should be no less than 250 volts, and rated power is more preferably greater than 60 watts.

The advantage of the utility model light adjustable power saving pulling switch is: 1, can change the brightness of illumination of bulb, be convenient to general family and use under the different time occasion; 2, can save energy behind the change light, because of voltage reduces, can prolong bulb service life simultaneously; 3, low cost product.

Below in conjunction with accompanying drawing the utility model light adjustable power saving pulling switch is described in further detail.

This accompanying drawing is the fundamental diagram of the utility model light adjustable power saving pulling switch.

As seen from the figure, the utility model light adjustable power saving pulling switch adopts a duplex pulling switch (1), this switch has a lead-in wire terminal (2), two leading-out terminals (3) and (4), between these two leading-out terminals (3) and (4), connect a semiconductor diode (5), this pipe ac resistance is pressed 250 volts, and 60 watts of rated power, this switch are to finish like this to become light: the live wire with alternating current inserts the switch lead-in wire terminal earlier, and the outlet of live wire can be appointed one that is connected in two switch leading-out terminals, for example (3) end links to each other with lighting bulb (6), when desiring to turn on light then, the pulling pulling switch, connect leading-out terminal (3) earlier, this moment, bulb circuit was logical, and lamp is bright.The diode because electric current is not flowed through, the bulb brightness maximum needs to become the light time, spur switch again, disconnect leading-out terminal (3), connect leading-out terminal (4), this moment, electric current was through diode, the all-wave of alternating current becomes half-wave, and it is about 1/2 that voltage descends, the bulb deepening, power be about just often 1/3, when desiring to turn off the light, spur that switch gets final product, so circulation is carried out again.

Claims

1, a kind of light adjustable power saving pulling switch comprises a duplex pulling switch, it is characterized in that: connect a semiconductor diode [5] between two leading-out terminals of this ganged switch.

2, light adjustable power saving pulling switch according to claim 1 is characterized in that, this semiconductor diode ac resistance is pressed more than 250 volts; Rated power is more than 60 watts.
