Abstract
The utility model relates to a stepless light adjusting energy-saving fluorescent lamp which is characterized in that a stepless light adjusting control circuit is arranged on a control switch; both ends of a lamp tube are connected with a ballast which is composed of a bridge rectifier circuit, a filter circuit, and a power-factor adjusting circuit; the other end of the ballast is connected with an output end of a light control switch. The utility model has the advantages of no electromagnetic noises, strong performance of resisting the interference of electromagnetic waves, and energy saving. The brightness of light can be optionally adjusted between 70-250V.
Description
The utility model relates to a kind of stepless dimming power-saving fluorescent lamp.
Power-saving fluorescent lamp in the market, as Chinese patent 91224811.4 is disclosed, form by the HPZ ballast, the HP fluorescent tube is applicable to AC-DC Circuit, the two ends negative electrode and the dual-purpose utmost point of fluorescent tube belong to thermode work, and the HPZ electric ballast is made up of many multiplication of voltages bridge rectifier and low frequency switch automatic control circuit.This power-saving fluorescent lamp for useful life of fluorescent lamp truly having certain prolongation, but must be joined the HPZ ballast by the HP fluorescent tube, and the scope of application is subjected to certain limitation.
The purpose of this utility model is the deficiency that overcomes foregoing invention, and a kind of durable energy saving fluorescent lamp that uses common fluorescent tube just can carry out stepless dimming is provided.
The purpose of this utility model is to realize like this.
Control switch, ballast and fluorescent tube are electrically connected in proper order, establish a stepless tunable light source control circuit on the control switch; The output that contains the ballast of rectification circuit, filter circuit, power factor (PF) regulating circuit formation can be electrically connected with 1 to 4 fluorescent tube, and the other end of ballast is electrically connected the stepless dimming control switch.
Owing to adopt such scheme; stepless dimming light fixture of the present utility model can arbitrarily be adjusted the brightness of fluorescent lamp between 70～250V; be suitable for different places; different personnel's demand; especially flash of light and stroboscopic that the conventional fluorescent lamps tool produces have been solved when starting; save the energy, prolonging lamp tube service life, and can reduce input current; improve power factor (PF); harmonic content is lower than national standard, no electromagnetic noise, and anti-electromagnetic wave disturbs; also can when mis-wired or short circuit, shut down automatically; the safety of protection light fixture can not only be controlled a tubes, and can carry out stepless dimming simultaneously to 2～4 tubes.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the utility model circuit theory diagrams.
1,2,3,4 is fluorescent tube among the figure.
In Fig. 1, establish stepless tunable optical control circuit R3, R4 on the switch enclosure base plate, controllable silicon SCR 1, SCR2T1 and inductance L 2, capacitor C 1～C3, voltage regulator A.The full-bridge type rectification circuit that ballast is made of D1～D4, L2, L3; The filter circuit that C4, C5, D5～D7 constitute; Abnormity protection circuit and C11～C14 that C7～C10, D8～D11, T2, T3 constitute, the power factor (PF) regulating circuit that L4～L7 constitutes constitutes.Can adopt a tubes to be connected with the output of ballast, the voltage regulator A of rotation tunable optical control switch can reach satisfied brightness.
(20～40W all can also can to adopt 2～4 tubes, decide on room-size) be connected with the output of ballast, for but the terminal voltage that guarantees 2～4 tubes is identical, an end of fluorescent tube is and connects, and can reach the purpose of 2～4 tubes light modulation simultaneously just the other end is series connection.
