Abstract
The utility model relates to an efficient electronic ballast for double lamps, which is mainly used as a ballast for florescent lamps. The utility model is mainly composed of a bridge type half-wave rectifying circuit which is composed of eight diodes and seven capacitors and four equivalent current-limiting resistors. The utility model has the advantages of simple structure, low cost, long service life, easy manufacture, and good electricity-saving effect.
Description
The utility model relates to a kind of new product of electric ballast, mainly is the ballast that is used for fluorescent lamp.
Existing inductance type ballast needs to be used with jumping bubble, and the two ends in fluorescent tube are provided with the filament starter respectively, because filament the has given hot inert gas of fluorescent tube, jump and steep and the acting in conjunction of ballast, the high voltage that produces punctures the inert gas in the fluorescent tube, and it is bright to start lamp; During the fluorescent tube operate as normal, alternating current is as the same through ballast.Existing Inductive ballast has following deficiency:
1, the ballast body has the copper loss iron loss, and the energising back produces eddy current, consumed power (being generally 9 watts).
2, when the voltage by ballast reduce to ± about 10%, or during room temperature sinking to the 10 ℃ left and right sides, especially can't starter, produce stroboscopic.Easily make fluorescent tube and jump bubble damage, the useful life of having reduced fluorescent tube.
3, ballast, jumping bubble, fluorescent tube need in parallel the use, promptly waste electric wire and also make troubles to installation.
4, complex manufacturing technology, manufacturer's power requirement equipment and electrical source of power or the like.
The purpose of this utility model is to provide a kind of fluorescent tube life-span, easy to install, manufacture craft is simple, power savings is good ballast of improving.
The purpose of this utility model is to realize like this, the utility model comprises housing, wiring board, forms the bridge-type half-wave rectifying circuit by eight diodes, seven electric capacity, again through four equivalent current-limiting resistances, be formed by connecting with fluorescent tube, finish above-mentioned purpose of the present utility model with this.
Product major advantage of the present utility model:
1, fluorescent tube long service life: but the life-span of using this ballast prolonging lamp tube since the direct voltage of this ballast after with rectification be 160V to fluorescent lamp power supply (normal working voltage 160V), starting resistor is 600V.Therefore, fluorescent tube does not have stroboscopic and jumping phenomena, so lamp tube service life is extended greatly, can be 3000 hours through its life-span of relevant test.
2, simple in structure, cost is low, improved starting voltage; And the fluorescent tube to filament breaking can recover to use, and need not jump bubble and connect the lead of jumping bubble by filament.
3, power savings is good: the resistance that this ballast adopted, the power consumption of electronic original parts such as diode is few.
4, manufacture craft is simple: make this ballast, need not device assembles get final product.
