Description

The extra low voltage electronic ballast glow-starter

The utility model relates to a kind of fluorescent-lamp-use electronic ballast glow-starter.

The ballast that fluorescent lamp is commonly used has two fiery classes with starter: a class is that inductor or capacitor reach the starter that matches with it; Another kind of is the electronic ballast glow-starter.For the electronic ballast glow-starter, structure has multiple, but all has some deficiency.The ballast starter that has is effective, does not influence lighting tube brightness, but complex structure; What have is simple in structure, energy starter under the low-voltage, but use long-time back fluorescent tube blackout, seriously reduced lighting tube brightness.

The purpose of this utility model is to release a kind of simple in structure, the electronic ballast glow-starter of the normal build-up of luminance of extra low voltage (being low to moderate 80 volts).

For reaching above-mentioned purpose, the technical scheme of proposition is: by diode D ₁, D ₂, D ₃, D ₄, D ₅And capacitor C ₂, C ₃, C ₄, C ₅Form voltage-multiplying circuit, make 220 volts of power supplys produce high voltage pulse: to be connected to bypass speed-up capacitor C by multiplication of voltage ₁, make the Filament of fluorescent lamp Fast Heating in the moment of power-on, accelerate to start; Be connected to coil L ₁, L ₂And diode D ₆, so that enough starting resistor and starting currents to be provided.Diode D, capacitor C, coil L are welded on the printed circuit board (PCB) according to circuit diagram, and printed circuit board (PCB) is fixedly mounted in the box that is made of shell.

There is following advantage the related electronic ballast glow-starter of the utility model: 1, starting resistor scope people even supply voltage is low to moderate 80 volts, also can make the normal starter of fluorescent lamp; 2, starting time is short, and start-up time was less than 0.5 second; 3, do not influence the brightness of fluorescent lamp, fluorescent tube does not turn black; 4, noiseless to microwave electrical equipment, as mobile telephone etc.; 5. noiseless, no stroboscopic 6, volume are little, in light weight when work, facility are installed, applied range; 7, economize on electricity can reach 30%.
