Abstract
The utility model discloses a dimming light whose filaments can be changed. The utility model is characterized in that the existing sequential electric connection that a one-filament lamp bulb and a voltage-regulating restrictor is replaced by the electric connection of a lamp bulb with a plurality of filaments, and a step switch which can contact different filaments respectively; the switch is composed of a parallel moving plate, one movable contact plate and a plurality of fixed contact plates. The utility model has the advantages that the different lighting powers can be selected by toggling the switch; the utilization rate of energy is high; the lighting quality is good.
Description
The utility model relates to a kind of desk lamp with dimmer switch.
At present, known desk lamp with dimmer switch structure is to be electrically connected and to be formed by the bulb that a filament is only arranged, adjustable current limliting or pressure regulator, switching sequence.The electric current or the voltage that change in the circuit just can make the bulb luminous intensity change.But luminous under under-voltage or low current situation, capacity usage ratio is very low, and luminous mass is also poor.
The purpose of this utility model provides a kind of desk lamp with dimmer switch, and it can select luminous intensity easily, and capacity usage ratio is very high and make simple.
The purpose of this utility model is achieved in that the bulb of the filament more than 2 groups of packing into or the lamp group of forming with the discrete bulb of identical wiring replace bulb, draw wiring and insert the moving fixed touching plate of step switch respectively in the bulb glass housing.Switch is that pack in a housing can parallel mobile notched plate, adorns movable contact spring on the plate, sets contact in the housing relevant position, links to each other with filament one end respectively, and common wire connects movable contact spring.Stir movable plate, just can connect filament respectively, realize the light modulation purpose.
Owing to adopt such scheme, solved poor efficiency, low-quality problem when carrying out low pressure, low current work with a filament, also make its prolongation greatly of receiving a mandate.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in the figure, be electric principle of the present utility model, structure chart and embodiment.
In the drawings, lamp socket (1) is loaded onto electrode (2), inserts several groups of filaments (3) of different capacity between electrode, and the glass envelope of packing into (4) constitutes bulb (or replace with the lamp group), and each electrode inserts step switch through line respectively.This switch is to close at plastics in (5), respectively fixing fixed touching plate (7); On a notched plate (8), load onto movable contact spring (6), reinstall during plastics close, it only can be moved horizontally and fixed touching plate is contacted respectively; Above movable plate, adorn one by 2 angles, can rotate and be fixed in a centre around the center and have the mobile device (9) that plate that chute can move up and down is formed; The top is equipped with and is played king's (making it the Chang Ju top); Backguy is equipped with at two angular distance axle places.Operation principle is: backguy on one side is toward drop-down, falls down to touch with side angle on the tooth of movable plate and descending along chute, and movable plate is passed to homonymy, and movable contact spring contacts with a fixed touching plate, and a filament is shinny; Loosen wiring, mobile device resets because of bullet Wang Zuoyong moves up; Backguy once more repeats last action, and movable contact spring contacts with another fixed touching plate, and another filament spot is finished light modulation work.Another root backguy of leaving behind, movable plate moves to other direction, and light modulation is carried out to inverse process.
Claims (3)
1, a kind of desk lamp with dimmer switch, a filament bulb, adjustable voltage or current limiter, switching sequence are electrically connected, and it is characterized in that: filament bulb is the lamp group of polylight or identical wiring, and adjustable voltage or current limiter are served as reasons and are moved the step switch that fixed touching plate constitutes.
2, the described desk lamp with dimmer switch of claim 1 is characterized in that: the filament in the bulb is more than 2 groups.
3, the described desk lamp with dimmer switch of claim 1 is characterized in that: the step switch movable plate is a dentation.
