Description

Electric capacity ballast sight lamp support

The utility model belongs to the startup and the ballast device of fluorescent lamp, relates to voltage multiplying rectifier and electric capacity choke circuit device.

Fluorescent lamp adopts the Inductive ballast ballast usually, the starter build-up of luminance, but Inductive ballast when work noise is big, and power consumption is many, uses starter to have start-up time long again, is difficult to the drawback of build-up of luminance under low voltage condition.Though the all-electronin ballast has fast starting, noise-free characteristics, there is the superpressure ability in this ballast, exciter tube superpressure easy burn-out, the shortcoming that price is high.Present in addition capacitive ballast patent, though as patent 91231162.2 grades solution of the above problems has been proposed, and since its cost height, the properties of product instability, impracticable for actual production.

The purpose of this utility model is for the shortcoming that overcomes above-mentioned fluorescent lamp ballast proposes a kind ofly to make the ballast element with electric capacity, good electric property, economize on electricity and low-cost electric capacitor ballast.

The utility model adopts voltage multiplying rectifier startup fluorescent lamp to carry out work, by diode D ₁, D ₂And capacitor C ₁, C ₂Constitute voltage doubling rectifing circuit, C ₁, C ₂Parameter be 3.3-4.1uF, the electric capacity that withstand voltage 350V is above connects last two capacitor C in hold concurrently two outputs (13), (14) of electric capacity ballasting circuit of voltage multiplying rectifier ₃, C ₄Play the assistant starting effect, a current-limiting resistance R connects between output (13) and light pipe, by high direct voltage the direct current positive and negative electrode directly is added on the filament of fluorescent tube two, because filament adds dc high voltage, the mercury of fluorescent tube is evaporated, produces electric high conduction and make lamp luminescence, diode D behind the power connection ₁, D ₂Conducting, capacitor C ₁, C ₂Charging, crest voltage can reach more than the 600V, because C ₁, C ₂Be to be attempted by lamp tube ends after the series connection, produce a very high voltage in lamp tube ends like this, be enough to start the sight fluorescent tube, after the fluorescent lamp startup is working properly, capacitor C ₁, C ₂Play metering function again, tube voltage does not raise or the voltage reduction, can both keep voltage steady, keeps the operate as normal of fluorescent lamp; The heat sink resistance of can between electric capacitor ballast and light pipe, connecting in addition; Also can utilize original coil ballast to be connected between electric capacitor ballast and the light pipe, play thermolysis.

The utility model adopts capacitor C ₁, C ₂Ballast, moment is brought up to peak value with voltage, provides high voltage to start, and makes fluorescent lamp also normal build-up of luminance under low-voltage and low temperature.The used element of the utility model is few, stable performance, the use of the fluorescent tube of the old and feeble fluorescent tube and the single, double head lamp pipe disintegration of filament can also being recovered lost eyesight, prolonging lamp tube service life, and little power consumption, the no noise of working, ratio of performance to price height.

Below in conjunction with accompanying drawing in detail CONSTRUCTED SPECIFICATION of the present utility model is described in detail:

By diode D ₁, D ₂Form voltage multiplying rectifier and electric capacity ballasting circuit, D ₁Negative pole and D ₂The tie point (11) and the C of positive pole ₁, C ₂Tie point (12) be the input of power supply, C ₁With D ₁Anodal tie point (13) and C ₂With D ₂The tie point of negative pole (14) is the output of this circuit.Be connected the capacitor C at (13), (14) two ends ₃, C ₄Play the assistant starting effect, especially the useless pipe of double end filament breaking is started more obviously, between output (13) and fluorescent tube, is connected a resistance R, a current limliting, dispel the heat and overcome the fluorescent tube flicker action.By high direct voltage the direct current positive and negative electrode directly is added on the filament of fluorescent tube two, because filament adds dc high voltage, the mercury of fluorescent tube is evaporated, generation ionization is conducted electricity and is made lamp luminescence, diode D behind the power connection ₁, D ₂Conducting, capacitor C ₁, C ₂Charging, crest voltage can reach more than the 600V, because C ₁, C ₂Be to be attempted by lamp tube ends after the series connection, produce a very high voltage in lamp tube ends like this, be enough to start fluorescent tube, after the fluorescent lamp startup is working properly, capacitor C ₁, C ₂Play metering function again, tube voltage does not raise or the voltage reduction, can both keep voltage steady, keeps the operate as normal of fluorescent lamp.Have two kinds in multiple installation method preferably, one when being to use the plain edition support, electric capacitor ballast and resistance R can be contained in respectively in the support shell, or take off starter and transform original coil into resistance and use.Two when being to use super book type support, this ballast is installed in the super book type stent foot one, and resistance directly is fixed in the support shell.

Below be component parameters:

C ₁, C ₂: 3.3-4.1uF, more than the withstand voltage 350V;

C ₃, C ₄: 6300P, more than the withstand voltage 630V;

D ₁, D ₂: the withstand voltage 1000V of crystal diode IN4007;

R: heatproof cement resistor 200-300 Ω, 5-20W.
