Description

The modularization fluorescent lamp

Technical field

The utility model relates to a kind of fluorescent lamp of circuit part in the light fixture being made module.

Background technology

A large amount of electric ballast fluorescent lamp light efficiency and life-spans of using all do not reach requirement in the market, and maintenance needs professional electrician's participation, and maintenance time is long, and maintenance process also will be closed general supply sometimes, has a strong impact on other people's normal electricity consumption.Thereby develop and a kind ofly have high-quality, high light efficiency, long-life, low price and the daylight light fixture that does not fast need to close general supply easy to maintenance is very urgent.

Summary of the invention

The purpose of this utility model is according to the market demand, a kind of high light efficiency, long-life is provided, price is low, fast easy to maintenance and need not closes the fluorescent lamp of general supply.

The thinking that reaches the utility model purpose is: 1, circuit part in the ordinary lamp and lantern is designed separately, make a convenient module of replacing, in case the module board accident is burnt, the consumer can replace the module of being burnt easily; 2, circuit part in the light fixture is made module, the consumer can freely select type, class and the function of circuit board according to demand.

The technical scheme (referring to accompanying drawing 1 and Fig. 2) that realizes the utility model purpose is: a kind of modularization fluorescent lamp, form by modular circuit M, lamp bracket H and fluorescent tube, A1, A2, A3, A4, A5 and six contacts of A6 are arranged on the modular circuit M, B1, B2, B3, B4, B5 and six contacts of B6 are arranged on the lamp bracket H, after module M inserts lamp bracket H, link to each other with six contacts on the lamp bracket H by six contacts on the module M, make lamp bracket H and module M form a complete daylight lamp circuit, fluorescent tube is loaded on the lamp interface T1 and T2 of lamp bracket H; Wherein the circuit of module M is made up of first (1) and second portion (2): first is a power supply direct current rectifying part, second portion is a resonance circuit, its power supply direct current rectification circuit: comprise 4 commutation diode D3 of the same type, D4, D5, D6 and capacitor C 1, by 4 commutation diode D3 of the same type, D4, D5 and D6 form bridge path rectification, export steady dc source through capacitor C 1 filtering; Resonance circuit: comprise 2 resistance R 1 and R2,5 capacitor C 2, C3, C4, C5 and C6,2 diode D1 and D2,2 triode VT1 and VT2, and oscillation transformer L1 and inductance L 2, triode VT1 wherein, diode D1, capacitor C 2 and oscillation transformer L1 form an amplifying circuit, triode VT2, diode D2, capacitor C 3 and oscillation transformer L1 form the another one amplifying circuit, two amplifiers compose in parallel a resonance circuit, with oscillation transformer L1 coupling output high frequency electric, with inductance L 2, capacitor C 4, C5 and C6 are composed in series resonance circuit, produce higher resonance potential fluorescent tube is ignited.

External power supply is through diode D3, D4, behind D5 and the D6 bridge path rectification, obtain direct power supply about 220V by capacitor C 1 filtering, dc source through resistance R 1, R2 to capacitor C 3 chargings, after capacitor C 3 both end voltage reach 0-7V, the conducting of triode VT2 positively biased, through oscillation transformer L1 coupling, when triode VT2 by conducting become by the time, triode VT1 then becomes conducting by ending, and triode VT1 and VT2 alternation form oscillatory regime like this; Oscillator signal boosts to export through oscillation transformer L1 and makes inductance L 2 and capacitor C 6 form the series resonant circuit resonance, produces higher resonance potential fluorescent tube is ignited.

After module M inserts lamp bracket H, link to each other with B1-B6 contact on the lamp bracket H, make complete daylight lamp circuit of lamp bracket and module composition, light fluorescent tube by the A1-A6 contact on the module M.Certain electronic devices and components burns for some reason in the ifs circuit, then whole module can be transferred to, and has changed a new module just, but livewire work.The benefit of doing like this is exactly easy to maintenance, and the consumer can freely select the type of modular circuit as required, for example inductive type, electron type, electricity-saving type, long-life type, different brightness, infrared remote control and time switch.
