Description

Starter for fluorescent lamp

The utility model relates to a kind of fluorescent lamp for lighting starter.

Present being seen glow starter is many to be made up of traditional ballast and starter, its major defect is that starting characteristic is bad under the low-pressure low-temperature, for example voltage instability regularly is being lower than the just difficult startup of 200V, poor reliability, starter is fragile, flicker sparking during startup, and the eyes to the people cause damage on the one hand, disturb other electrical equipment on the other hand, and cause the fluorescent tube life-span short.

It is low that the purpose of this utility model provides a kind of starting resistor, easily starts, can not cause the glow starter of fluorescent tube stroboscopic, obvious energy conservation, fluorescent tube and starter long service life.

Technical solution of the present utility model is achieved like this, there are inductance coil L1, L2, L3, capacitor C and four terminals in starter inside, its connected mode is that inductance coil L1, L2, L3 form series connection, the free end of L1 is described terminals, the free end of L3 also is described another terminals, one end of capacitor C links to each other with the series connection end of L1 and L2, and its other end links to each other with the 3rd terminals, and the series connection end of described L2 and L3 is that described the 4th terminals link to each other.

Connect end and zero line that capacitor C is coupled in L1 and L2 form resonant tank, and the capacitor C two ends produce higher voltage, boost through L2, and the L3 preheating filament reaches to start and forms.The utility model is open circuit when zero load, so there is not no-load current, according to the size of electric capacity, power factor (PF) can bring up to 0.90 to 0.98 by original below 0.5, and total current descends 40% to 50% by original 410mA.After startup, L1+L2 forms ballast inductance L simultaneously, and capacitance compensation power reaches energy-conservation.The utility model startup because the resonance principle of employing inductance capacitance coupling and complementing boosts does not need starter, has so just got rid of the common fault of starter, particularly being lower than below the 220V when voltage, when 150V is above, all can once start fast.

The utility model has the advantages that starting resistor is low, easily start, can not cause the fluorescent tube stroboscopic, fluorescent tube and starter long service life, and obvious energy conservation, safety, noiselessness, simple in structure, cheap.

Below in conjunction with accompanying drawing embodiment of the present utility model is explained in detail.

Fig. 1, organigram of the present utility model.

Embodiment one,

According to Fig. 1, the utility model a shell is arranged, terminals (1), (2), (3), (4) are arranged, particularly enclosure has inductance coil L1, L2, L3 and capacitor C, its connected mode is that inductance coil L1, L2, L3 form series connection, the free end of L1 is described terminals (1), the free end of L3 is described terminals (4), one end of capacitor C links to each other with the series connection end of L1 and L2, its other end is described terminals (2), and the series connection end of described L2 and L3 is described terminals (3).

Terminals of the present utility model (1) connect power firestreak, and zero line directly advances an end of fluorescent tube, and terminals (2) connect fluorescent tube, become the loop by filament with zero line, and terminals (3) and terminals (4) connect the other end of fluorescent tube.Behind the power connection, power supply by terminals (1) through L1, capacitor C, terminals (2) are connected with zero line through filament again, form resonant tank, make the capacitor C two ends produce higher voltage, boost through L2, L3 terminals (3), (4) preheating filament reach startup, start the back and form ballast inductance L by L1+L2, capacitance compensation power reaches energy-conservation.

Starter of the present utility model can also start two fluorescent tubes by a starter, and its effect is better than single tube.

Claims

1, illuminating a kind of glow starter, comprise that shell, terminals (1), (2), (3), (4) form, it is characterized in that there are inductance coil L1, L2, L3 and capacitor C in glow starter inside, its connected mode is that inductance coil L1, L2, L3 form series connection, the free end of L1 is described terminals (1), the free end of L3 is described terminals (4), one end of capacitor C links to each other with the series connection end of L1 and L2, its other end is described terminals (2), and the series connection end of described L2 and L3 is described terminals (3).
