Description

Ballast for energy-savnig lamp with low pressure 36V

Technical field

The utility model relates to a kind of ballast for energy-savnig lamp with low pressure 36V, is applied to the illumination in the places such as lathe, mine.

Background technology

Because domestic seldom company develops corresponding energy-conserving light source product for this special occasions, also there is the more market vacancy in the domestic market in the prior art.At present, the user overwhelming majority also using the contour energy-consuming product of incandescent lamp bulb, causes energy significant wastage.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of ballast for energy-savnig lamp with low pressure 36V is provided, the technical scheme that its technical problem that solves the utility model adopts is: structure of the present utility model comprises the voltage-multiplying circuit module, the half-bridge oscillation circuit module, from even booster circuit module, the filament pre-heating line module, it is characterized in that the voltage-multiplying circuit module is connected with the half-bridge oscillation circuit module, the half-bridge oscillation circuit module is connected with the filament pre-heating line module respectively with from even booster circuit module, in parallel from even booster circuit module and filament pre-heating line module, be connected with fluorescent tube from even booster circuit module, the filament pre-heating line module also is connected with fluorescent tube, together fluorescent tube is lighted by the high pressure that obtains the 600V that high frequency voltage and filament pre-heating line module induce from even booster circuit module.

Operation principle: become the direct voltage about 90V after at first the 36V alternating current being boosted through voltage-multiplying circuit, then pass through half-bridge oscillation circuit, the 90V direct current is converted to alternating current about frequency 35kHz, from the primary winding of even booster circuit and with capacitor C 9 on, obtain high frequency voltage, its auxiliary winding induces the high pressure of volt more than 600 simultaneously, therewith fluorescent tube is lighted, the filament pre-heating circuit is as the part of the auxiliary winding of transformer, induce small voltage, give filament pre-heating, thereby prolong the life-span of filament.

The beneficial effects of the utility model are that the utility model prolongs burn-out life, and is energy-saving and cost-reducing, for the user has reduced certain financial burden.
