Description

Low voltage glow starting and lightness intensifing device for fluorescent lamp

The utility model is that a kind of fluorescent lamp low-voltage starter increases funerary objects, and it belongs to the starting drive field of discharge lamp igniting.

Traditional starter for fluorescent is made of the neon bulb and the antispark electric capacity of parallel connection.When fluorescent lamp rigidly connects energize, neon bulb is with regard to the build-up of luminance conducting of discharging in the starter, make two groups of filament series connections on power supply, the filament heating, launch a large amount of electronics, the bimetal leaf expanded by heating was in contact with one another two metal sheets when neon bulb discharged in the starter, caused neon bulb discharge quenching in the starter, and the bimetal leaf cooling disconnects immediately.Because the unexpected disconnection of sheet metal causes line current to change suddenly,, make the fluorescent tube discharge enter operating state so produce high open circuit pulse voltage at the ballast two ends.But in low pressure, voltage is lower than under 180 volts the situation, and fluorescent lamp just can not normally start, or causes repeatedly and start, even can not start, and in addition, because the operating current during circuit start is bigger, thereby cause causing following adverse consequences: filament easily is blown; Lamp tube ends is easily turned black and is worn out; Reduce the useful life of fluorescent tube.

The purpose of this utility model is, provide a kind of low-voltage starter to increase funerary objects, it is long that this starting and lightness intensifing device can solve start-up time of fluorescent lamp effectively, often, the problem that under the low situation of line voltage, starts difficulty even can not start, also can increase the brightness of fluorescent lamp in addition, prolong the life-span of fluorescent tube.

The utility model comprises capacitor, resistance, inductance element and shell.The circuit of connecting with another capacitor and inductance element again after one capacitor and the resistance series connection is in parallel, and the outside is with on the jacket, and the utility model can exchange with the traditional fluorescent lamp starter, need not change any parts.

Capacitor of the present utility model all gets final product greater than 400V with the proof voltage value, and its value is the best with 2 μ f; The value of resistance is the best with 200 Ω, and power is greater than 1.5W; And inductance element can replace with fluorescent lamp ballast.

Therefore the utility model has following advantage than prior art owing to adopt the LC resonance principle:

1, under voltage drop is low to moderate 110 volts low pressure situation, still can once open fluorescent lamp, flicker free phenomenon fast;

2, the light that sends of fluorescent tube is softer, bright;

3, the daylight filament is difficult for being blown, the useful life of extended day light modulation;

Even the useless fluorescent tube that 4 one or both ends filaments have all opened circuit, but also operate as normal, method are that end two lamp bases that open circuit are connected.

Accompanying drawing is that to use the utility model be starting and lightness intensifing device operation principle schematic diagram at the bottom of the fluorescent lamp to fluorescent lamp." 1 ", " 2 " are capacitor among the figure, and " 3 " are resistance, and " 4 " are inductance element, and " 5 " are shell, and " 6 " are fluorescent tube, and " 7 " are ballast.

The utility model is described in further detail below in conjunction with accompanying drawing: the circuit of connecting with capacitor " 2 " and inductance element " 4 " again after capacitor " 1 " and resistance " 3 " series connection is in parallel, and the outside is with on shell " 5 " cover.Need only when the utility model uses with the traditional fluorescent lamp starter and exchange, and need not change any parts.

Claims (1)

1, a kind of fluorescent lamp low-voltage starter increases funerary objects, comprise capacitor " 1 ", capacitor " 2 ", resistance " 3 ", inductance element " 4 " and shell " 5 ", it is characterized in that capacitor " 1 " and resistance " 3 ", inductance element " 4 " and shell " 5 ", it is characterized in that the circuit of connecting with capacitor " 2 " and inductance element " 4 " again after the series connection of capacitor " 1 " and resistance " 3 " is in parallel.
