Abstract
The utility model provides an improved glow starter for fluorescent lamps, being suitable for regular fluorescent lamps. The utility model is formed by series connection of the neon bulb of a regular glow starter for fluorescent lamps and a diode. The way of connection enables a starting current to flow from the stationary contact of the neon bulb to the contact point. A half-wave rectification is made to a filament starting current, the starting current is added, the starting times are reduced when the power supply voltage and the air temperature of the fluorescent lamp are low, and the service life of the fluorescent lamp tube is extended by the utility model. The utility model can also be used when the power supply voltage is normal.
Description
The utility model relates to a kind of improved starter for fluorescent.Be applicable to common fluorescent lamp.
In recent years, on the lighting market various electric ballasts have appearred.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 to 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.Supply voltage just often also can use.
The utility model is achieved in that a starter neon bulb and a diode are in series, and the positive pole of diode is connected to the movable contact spring of neon bulb, or the negative pole of diode is connected to the static contact of neon bulb.After daylight lamp power source was connected, the neon bulb movable contact spring produced aura, and back contact static contact is heated.At this moment the electric current that flows through fluorescent lamp ballast is the dc pulse electric current, and greater than the starting current that normal starter produces, filament obtains better preheating, and the electromotive force of generation also increases, thereby has improved startability.Supply voltage just often, because of the time of contact contact very short, can the disintegration of filament, so also can normally use.
The utility model has only increased the startability that a diode has promptly improved fluorescent lamp, makes that fluorescent lamp is 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 starter neon bulb N are in series.C is anti-tampering electric capacity.The negative pole of diode is connected with the static contact of neon bulb N.The specification of D is greater than 1A, and 400V gets final product.This starter is applicable to the 4-40W fluorescent lamp.
Claims (1)
- A kind of starter for fluorescent that is made of diode and the series connection of starter neon bulb it is characterized in that the negative pole of diode and the fixed contact of starter neon bulb, or the positive pole of diode is connected with the moving contact of starter neon bulb.
