Abstract

The utility model relates to a glow lighting apparatus for a fluorescent lamp, which starts glow fast in a low voltage. The utility model is especially suitable for the fluorescent lamp lighting in low battery regions, and is composed of a differentiating circuit (1), a monostable trigger circuit and a lamp tube. The utility model realizes glow starting fast in a low voltage and low temperature, stable lighting and voltage-stabilizing and current limiting in a high voltage, has the advantages of high efficiency, energy saving, freedom from a flicker and a buzz, long life time, etc., and is a fluorescent lamp lighting fitting with a good practicability.

Description

Fluorescent lamp brightness funerary objects

The utility model relates to a kind of fluorescent lamp brightness funerary objects of low pressure fast starting.

Existing fluorescent lamp inductance type ballast fluorescent tube when operating voltage declines by a big margin is difficult to starter, is in the big situation of scope range of the fluctuation of voltage for a long time, and lamp tube ends is easily turned black and be impaired.As for selling a lot of electric ballast of kind in the market, though respectively have characteristics, its reliability, economy and maintainability are also unsatisfactory, fail to popularize and use.

The purpose of this utility model is to develop a kind of collection fluorescent lamp starter, current limliting, function such as energy-conservation is an one; the fluorescent lamp brightness funerary objects that practicality is good; it had both kept the advantage of inductance type ballast good reliability; can overcome again electric ballast remain easily burn, weakness such as life-span weak point, cost height; realize that low-temp low-pressure can starter, steady illumination, and to the high pressure current limliting effectively that rises; it is durable in use to play the protection fluorescent tube, and can obtain the effect of energy saving.

The purpose of this utility model is achieved in that it is made up of differential circuit, single-shot trigger trigger and fluorescent tube.Differential circuit and single-shot trigger trigger serve as the effect of starter and current limliting.When brightness funerary objects energized, differential circuit produces instantaneous high pressure, quickens fluorescent tube moment starter, and single-shot trigger trigger work this moment makes the lamp tube ends filament form power circuit, excites ionization and lights.Behind the starter, single-shot trigger trigger quits work, and differential circuit still plays metering function.

The utlity model has following characteristics and remarkable result:

1. can starter when realizing low pressure, but current limliting during high pressure, the protection fluorescent tube is not impaired, prolonging lamp tube service life, and brightness funerary objects itself is also long useful life.

2. can disposable reliable starter when voltage drops to 130V, starting time is less than 1 second, all can steady illumination at voltage 130～260V scope fluorescent tube, the user who is particularly useful for the power shortage area uses.

3. owing to be capacitive load, improved power factor, then can reduce the circuit power consumption widely, compared with inductance type ballast, but power saving 20～30%, and light is brighter.

4. it is applicable to that also light fixtures such as the identical all kinds of annular lamp of power, wall lamp, electricity-saving lamp use.

The utility model through the Zhangzhou City product quality inspection examine and determine the requirement of conformance with standard regulation.Retrieve through Fujian Province's scientific information research and to look into new result, the documents and materials identical with it, patent and achievement are not arranged.

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

Fig. 1 is the electrical schematic diagram of the utility model embodiment, and it is made up of differential circuit (1), single-shot trigger trigger (2) and fluorescent tube (3).Differential circuit (1) is made of inductance L, capacitor C, resistance R and fluorescent tube (3).Single-shot trigger trigger (2) is made of the sub-assembly circuit that adopts electronics unit, device.Differential circuit (1) and single-shot trigger trigger (2) all collect and are contained in the housing.

Among Fig. 1, when the power turn-on K switch, differential circuit (1) produces instantaneous high pressure, the open circuit voltage of fluorescent tube (3) is raise, quicken light moment starter, single-shot trigger trigger this moment (2) is started working, make fluorescent tube two filament form power circuit, excite the fluorescent tube gas ionization and light.Behind the starter, the hurried decline of fluorescent tube (3) both end voltage, single-shot trigger trigger (2) then cuts off the power supply automatically and quits work.Differential circuit (1) still plays the current stabilization effect when fluorescent tube is in normal illumination, keep the stable operating state of fluorescent tube.

Energy fast starting when the utility model has been realized low-pressure low-temperature, energy voltage stabilizing current limliting during high pressure, tool Have efficient, energy-conservation, flicker free, no hum, and the life-span of fluorescent tube and brightness funerary objects itself is long etc. excellent The point. Use through lasting illumination more than a year, the user in the power shortage area uses especially, obtains Get significant Effectiveness and benefit, be subjected to the user and welcome.
