Description
Affiliated technical field
The utility model belongs to lighting technical field, relates in particular to energy-saving health fluorescent lamp.
Background technology
The conventional fluorescent lamps of using generally comprises fluorescent lamp, ballast, starter and four parts of light fixture at present.Fluorescent tube is coated layer of fluorescent powder by the glass tube inwall, and two ends respectively connect a filament electrode, fills after the exhaust with an amount of argon gas or other inert gas and mercury or mercury vapour.Ballast has two kinds of inductance type and electronic types.The fluorescent lamp of Inductive ballast is because of using the alternating current of 50 hertz or 60 hertz, so its light intensity changed in 1 second 100 times or 120 times.This have the phosphere of frequency to be called stroboscopic, eyesight influence to the people is very big, the machine mistake that normal high speed is changeed is regarded slow-speed as and is very arrived commentaries on classics, the ball of high-speed flight mistake sees it is interrupted on the court, or the like, particularly eyes are caused fatigue easily, outstanding and be under fluorescent lighting, to read a book, children's eyesight there is certain infringement.In addition, the consumed power of Inductive ballast own is also more, also needs enamelled wire and silicon steel sheet, and fluorescent lamp has the current value of an optimal luminescent efficient, because the cycle of alternating current changes, some electric current surpasses this optimum amounts of current, causes waste of electric energy.And at the very difficult starter in the lower rural area of voltage ratio.Therefore, a lot of in recent years engineers and technicians are considering the method how to replace always.
Holland the Philip in early eighties, at first developed a kind of can be at high frequency state (30
-60 kilo hertzs) the following electric ballast of work, because its optical efficiency height, can be at starter under the low-voltage, without copper material and steel, so it payes attention to once occurring being subjected to people immediately, wishes to replace original Inductive ballast with it.China China National Light Industrial Products Department also classifies it as emphasis and supports one of product.But it does not fundamentally eliminate stroboscopic phenomenon, and the low frequency stroboscopic does not thoroughly solve yet, and is at mains frequencies modulated high frequency.That is to say the low frequency stroboscopic of existing 50 hertz or 60 hertz, have 30 again
-60 kilo hertzs high frequency stroboscopic, just lighter than Inductive ballast on the degree of low frequency stroboscopic, smaller to visual acuity affected.
Summary of the invention
The purpose of this utility model provides and a kind ofly can reduce ballast power consumption, improves the fluorescent tube luminous efficiency, can keep not having the energy-conservation health protection fluorescent lamp of stroboscopic and low-voltage starter again.
The technical solution of the utility model is:
Adopt voltage-multiplying circuit as starting circuit; Constitute operating circuit by reduction voltage circuit, bridge rectifier, voltage doubling rectifing circuit and current stabilization circuit series connection.That is:
A kind of energy-saving health fluorescent lamp comprises fluorescent tube, dc electronic ballast and three parts of light fixture; Said dc electronic ballast comprises starting circuit and operating circuit; Said starting circuit is a voltage doubling rectifing circuit; Said operating circuit is minimum to be made of reduction voltage circuit, bridge rectifier and current stabilization circuit series connection; It is characterized in that: have the multiplication of voltage current stabilization circuit to be connected between the bridge rectifier and current stabilization circuit of operating circuit.
The beneficial effects of the utility model: because above-mentioned architectural feature, so but the utlity model has low-voltage starter, DC operation and do not have the advantage that the luminosity of stroboscopic, long service life, positive terminal can not weaken.
