Abstract
The utility model relates to a light regulating and electricity saving device for a fluorescent lamp, which is composed of a panel and an adjusting knob of a potentiometer arranged on the panel. A circuit board is arranged between the panel and a back cover, the lines of the circuit board is composed of a silicon controlled rectifier, a bidirectional trigger diode, a resistor, a potentiometer, a capacitor and inductance components. The stepless light regulation to a fluorescent lamp can be realized, and a power saving effect can be realized. The utility model has the advantages of simple circuit of devices and easy adoption of users.
Description
The utility model relates to a kind of dimmer, particularly a kind of adjusting brightness of fluorescent lamp electricity-saving appliance.
Present dimmer and desk lamp with dimmer switch all are that incandescent lamp is carried out light modulation.And fluorescent lamp is carried out light modulation, especially stepless dimming does not also have simple and easy to do method.
The purpose of this utility model provides a kind of adjusting brightness of fluorescent lamp electricity-saving appliance.Can carry out light modulation to fluorescent lamp, overcome above-mentioned shortcoming and defect.
The purpose of this utility model is achieved in that
A kind of adjusting brightness of fluorescent lamp electricity-saving appliance is characterized in that by being made up of adjusting knob, the bonnet of potentiometer on panel, the panel: between panel and the bonnet wiring board is arranged, controllable silicon, bidirectional trigger diode, resistance, electric capacity, inductance element are arranged on its wiring board, its circuit is: a two-way controllable silicon is arranged, resistance, potentiometer and an electric capacity of connecting is connected in parallel, potentiometer and electric capacity tie point connect a two-way diac, another termination The Trigger of Bidirectional Triode Thyristor utmost point of two utmost point trigger tubes; The two ends of bidirectional triode thyristor respectively connect an inductance, connect an electric capacity between the other end of two inductance, and are the two-end-point of light adjusting circuit.
But the two ends parallel resistance of potentiometer.
The utility model has the advantages that:
Can carry out electrodeless light modulation to fluorescent lamp.Can reach power savings, this device circuitry is simple, and cost is low, and the user is acceptant.
Below in conjunction with description of drawings embodiment:
Fig. 1 is an adjusting brightness of fluorescent lamp electricity-saving appliance appearance structure schematic diagram
Fig. 2 is an adjusting brightness of fluorescent lamp electricity-saving appliance circuit diagram
Fig. 3 is to use the fluorescent lamp circuit figure of adjusting brightness of fluorescent lamp electricity-saving appliance
A kind of adjusting brightness of fluorescent lamp electricity-saving appliance has panel 1, the adjusting knob 2 that potentiometer W is arranged on the panel, bonnet 3 is formed, wiring board 4 is arranged between panel and the bonnet, controllable silicon 3CT is arranged on its wiring board, bidirectional trigger diode DB3, resistance R 1, R2, capacitor C 1, C2, inductance component L 1, L2, its circuit is: by bidirectional triode thyristor 3CT, a resistance R 1 of connecting is connected in parallel, potentiometer W and capacitor C 1, a potentiometer W resistance R 2 in parallel, potentiometer W and capacitor C 1 tie point meet bidirectional triode thyristor trigger tube DB3, another termination The Trigger of Bidirectional Triode Thyristor utmost point of trigger tube, the two ends of bidirectional triode thyristor respectively connect an inductance L 1, L2, connect a capacitor C 2 between the other end of two inductance, and be the two-end-point of light adjusting circuit.
In the circuit of adjusting brightness of fluorescent lamp, change the value of W, can also carry out stepless dimming fluorescent lamp.Two inductance L 1 and L2 enter in power supply and the daylight lamp circuit with better prevention high order harmonic component.
Light adjusting circuit also can adopt other any typical controllable silicon light modulation circuit.When fluorescent lamp is in dark attitude, when economize on electricity all can be bright attitude more than 50%.
Use that T is the adjusting brightness of fluorescent lamp electricity-saving appliance among Fig. 3 of fluorescent lamp circuit figure of adjusting brightness of fluorescent lamp electricity-saving appliance, L3 is a ballast, and Q is a starter, and Y is a fluorescent lamp.
