Abstract

The utility model relates to an electronic starter with long service life used for starting of a fluorescent lamp. The starter is composed of a capacitor, controllable silicon, a resistor and contact points. After powered up, the starter provides starting electric voltage which makes the fluorescent lamp start. After the fluorescent lamp is started, the starter stops working. The utility model has the advantages of long service life, stable and reliable performance and widely applicable range for voltages. The utility model can also prolong the service life of the fluorescent lamp.

Description

Longlife electronic starter

The utility model relates to a kind of starter device of fluorescent lamp, especially the electronic starter of the fluorescent lamp of forming with electronic circuit.

At present, known fluorescence lamp starter is made up of neon bulb, electric capacity and shell etc.It utilizes the disconnection of the metal in the neon bulb to produce a higher voltage by ballast at the fluorescent tube two ends and makes it starter.But the life-span of this starter is shorter, and the sheet metal in neon bulb is sticked together, or during the shunt capacitance puncture short, lamp tube ends is rubescent, and the centre does not work, if untimely replacing starter then Filament of fluorescent lamp blow very soon, fluorescent lamp is scrapped.

The utility model provides a kind of long-life electronic starter, and it can not only make the fluorescent lamp starter reliably, and its useful life is very long, and can prolong the useful life of fluorescent lamp.

The purpose of this utility model is achieved in that in insulation crust, front contact is connected with electric capacity one end, the other end of electric capacity is connected with silicon controlled one end, the silicon controlled other end is connected with back contact, controls between the utmost point with silicon controlled tie point and silicon controlled at electric capacity to be connected a resistance.During use the contact, front and back of long-life electronic starter is received the two ends of fluorescent lamp respectively, after energized, the long-life electronic starter produces a higher voltage at the two ends of fluorescent lamp and makes the fluorescent lamp starter, and the fluorescent tube both end voltage is lower behind the starter, and the long-life electronic starter quits work.

Because adopt such scheme, the utility model is starter reliably, it is simple in structure, long service life, and it is wide to be suitable for voltage range, and can prolong the useful life of fluorescent lamp.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model circuit theory diagrams.

Fig. 2 is the long-life electronic starter and the figure that connects of fluorescent lamp, ballast.

1. front contacts, 2. back contacts, 3. electric capacity, 4. controllable silicons, 5. resistance, 6. fluorescent lamps, 7. ballasts, 8. long-life electronic starter among the figure

Front contact in Fig. 1 (1) is connected with an end of electric capacity (3), the other end of electric capacity (3) is connected with the other end of controllable silicon (4), resistance (5) is connected between the control utmost point of the tie point of electric capacity (3) and controllable silicon (4) and controllable silicon (4), and the silicon controlled other end is connected with back contact (2).

In embodiment illustrated in fig. 2, the utility model and fluorescent lamp are in parallel, front contact (1), back contact (2), link to each other with the fluorescent lamp two ends respectively, ballast (7) is connected with fluorescent lamp (6) one ends, and the other end of ballast and the other end of fluorescent lamp insert power supply.After powering up, its voltage is added on front contact of the present utility model (1) back contact (2) through the filament of ballast (7) and fluorescent lamp (6), when alternating voltage is raised to certain numerical value, make the controllable silicon conducting, electric capacity is charged, thereby make ballast produce a higher voltage, be added on the two ends of fluorescent lamp and make it starter.
