Electronic lamp tube starter

The startup stabilizer of the relevant a kind of gas discharge tube of the utility model refers to a kind ofly applicable to the different capacity fluorescent tube especially, and can save power consumption and prolonging lamp tube service life.

The illumination of being used at present, adorn and show and decorative lamp, the most extensive with the use of gas discharge tube, all belong to this type of fluorescent tube as fluorescent lamp, neon light.

Existing this type of discharge tube mainly all radiates electronics with fluorescent tube two lateral electrodes, and sends invisible ultraviolet light with the inner blanketing gas of fluorescent tube (as mercury vapor) collision, and this UV-irradiation is launched visible light in the fluorescent slaine of tube inner wall.Can produce the fluorescent tube of different colours by the selection of different fluorescent things.

The conventional discharge lamps pipe must make its gas discharge when lighting, need again after lighting to make its stabilized illumination with suitable electric current.Therefore, equal at existing fluorescent lamp, comprise stabilizer and starter two necessary elements.But generally use the starter of bimetal leaf often to break down, the life-span of fluorescent tube is also not long.

Therefore, be the fluorescent start of electronic type to be arranged and stabilizer is developed and use in a large number.Existing electronic type fluorescent start and stabilizer are mostly with an oscillating circuit heat filament and generation potential pulse, both sides, fluorescent tube discharge back filament promptly fails, only depend on the interior mercury atom bump filament of fluorescent tube to make it to keep certain high temperature, and it is luminous to utilize the electronic type current-limiting circuit to order about the fluorescent tube continuous discharge.This mode fails because of filament, so fluorescent tube must make the fluorescent tube fluorescent layer fragile could regular picture than under the higher voltage luminous, influences fluorescent tube useful life, and this kind mode is also than power consumption certainly.

In addition, general fluorescent tube all has multiple different size, and old electronic type fluorescent start and stabilizer must design a kind of circuit at each different capacity, and be obvious also quite undesirable.

The utility model aims to provide a kind of startup stabilizer of gas discharge tube, give filter rectification through a power supply circuit when making the power supply input, select through voltage again, produce the higher-order of oscillation by an oscillating circuit and be connected to a lamp circuit, this lamp circuit is with twice level coils of a capacitances in series, and make two of a coil wherein be connected to fluorescent lamp one side, the fluorescent lamp in addition side resistance of then connecting is connected to power end, above-mentioned two series connection secondary coils make fluorescent tube one side lamp silk still continue to have electric current to pass through heating behind the fluorescent tube Discharge illuminating, and it is luminous to keep fluorescent lamp with low-voltage, use saving power consumption, prolonging lamp tube service life, and it can be applied to the fluorescent tube of different capacity.
