Description

Multifunction contactless micro electric starter

The utility model belongs to starter, especially a kind of multi-functional contactless micro electric starter.

Existing commercially available starter, civil power forces down when 180V, is difficult to starter, and light pipe constantly glimmers, and makes the lost of life of light pipe, and starter is bad easily, often the trouble of changing.And commercially available electric ballast, low-voltage starter is good, but costs an arm and a leg, the failure rate height, and the life-span is short, has generally gone bad and can not repair.

The purpose of this utility model be to provide a kind of simple in structure, energy-conservation, contactless, durable, versatility wide, in city voltage 140-260 volt scope, the light pipe that particularly burns out, can both moment the starter of starter flicker free.

Technical solution scheme of the present utility model is such, comprises by the rectification current-limiting circuit circuits for triggering, the electronic switch charging starting circuit that boosts.

The utility model has the advantages that, simple in structure, contactless, durable, energy-conservation, versatility is wide, makes the light pipe (air tight) that burns out can be in city voltage 140-260 volt scope, moment the starter flicker free, prolong light pipe useful life, the light pipe that is suitable for different capacity uses.

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

Accompanying drawing is a structure electrical schematic diagram of the present utility model.

In circuit shown in the accompanying drawing, the diode D1 and the resistance R 3 of rectification current-limiting circuit are serially connected in the circuit, the triode T1c utmost point of circuits for triggering connects resistance R 3, R1, the b utmost point meets R1, R2, the e utmost point connects the trigger electrode of R4 and controllable silicon T2, the R4 other end is connected with the R2 other end, the electric capacity c of electronic switch charge boost circuit connects the D1 positive pole, another termination controllable silicon T2 positive pole of c and the negative pole of diode D2, D2 positive pole, T2 negative pole, resistance R 2, R4 connect back (a point) lead-in wire and connect light pipe one end filament, and D1 positive pole (b point) lead-in wire connects light pipe other end filament.

The utility model operation principle is: when a point is positive half cycle, electric capacity c charging, when the b point is that timing diode D2 is anti-inclined to one side, diode D1 conducting simultaneously, triode T1 is provided operating current, and trigger controllable silicon T2 conducting simultaneously, make 600 volts of above high pressure of circuit moment generation act on fluorescent tube and make the interior gas discharge of pipe and put fluorescent lamp.

The utility model most preferred embodiment, shown in accompanying drawing, electric capacity c is with more than the 1WF/630V, T2 is the unidirectional controllable silicon of 1A/1000, diode D1, D2 be with 1N4004 or 1N4007, after the element of circuit is welded, is contained in the box body, a, b point lead-in wire connects light pipe, is preferably made existing commercially available starter and equally installs and uses.
