Abstract
The utility model provides an improved glow starter for fluorescent lamps, which is suitable for general fluorescent lamps. The utility model is formed by serially connected the neon bulb of a glow starter for a general fluorescent lamp with a diode which is parallelly connected with a resistor. A half-wave rectification is made to a filament starting current by the utility model. The starting current is added, and the starting times of the fluorescent lamp are reduced when the power supply voltage and the air temperature are low. The utility model has the advantages of long service life, and high reliability.
Description
The utility model relates to a kind of improved starter for fluorescent.Be applicable to common fluorescent lamp.
In recent years, various electric ballasts have been begun to occur on the lighting market.But for various reasons, using the most general in a few years from now on will be common ballast.Existing common starter for fluorescent mainly is made of the neon bulb that contains two contacts.On the low side or when temperature is low at supply voltage, can not start fluorescent lamp well, often need start repeatedly, this must have influence on the life-span of fluorescent tube.
Task of the present utility model is that a kind of improved fluorescent lamp starter will be provided, and when the on the low side and temperature of supply voltage is low, can improve the startability of fluorescent lamp.
The utility model is achieved in that series connection semiconductor diode in former starter neon bulb circuit, and the two ends of this diode and a resistance are the resistance in thousands of Europe.Daylight lamp power source rigidly connects when logical, and very little by the electric current of neon bulb, the impedance that diode presents is very big, the electric current resistance of mainly flowing through.After two contacts of neon bulb are subjected to thermo-contact, the electric current of lighting filament of fluorescent lamp mainly is through diode in half cycle, in another half cycle, diode ends, the electric current resistance of flowing through, impedance during diode current flow is much smaller than resistance on it in parallel, and the electric current of filament of fluorescent lamp is the dc pulse electric current basically so the electric current of half cycle much larger than the electric current of another half cycle, is promptly flowed through.Fluorescent lamp ballast diminishes to the impedance of this electric current, thus the starting current increase, thus improved startability.
The utility model has only increased the startability that a diode and resistance have promptly improved fluorescent lamp, makes fluorescent lamp lower at voltage, also can work when temperature is low.Reduced the number of starts, and be negative correlation with the number of starts useful life of fluorescent lamp, thereby prolonged its useful life.
The utility model will be further described below with reference to accompanying drawing.
With reference to accompanying drawing, diode D and resistance R are in parallel, and are in series with neon bulb N again.C is anti-tampering electric capacity.R also can replace by capacitor, but can increase cost.The R resistance is thousands of Europe (are applicable to 8---40W fluorescent lamp), and the specification of D is greater than 1A, and 500V gets final product.
