CN2140603Y - Long service energy saving fluorescent lamp - Google Patents

Abstract

The utility model relates to a long service energy saving fluorescent lamp. The circuit thereof is connected in series with both ends of the energy source. The circuit adopts a ballast, a starter and a capacitor. The fluorescent tube, the starter and the capacitor are connected in parallel. The filament can not be burn down because a circuit is not formed in the filament of the fluorescent tube when the utility model starts. Therefore, the long service energy saving fluorescent lamp prolongs the service life of fluorescent tube. The long service energy saving fluorescent lamp avoids the waste caused by high-current heating lamp when the fluorescent lamp starts owing to the high-voltage discharge glow starting. Owing to an added capacitor 4 in the circuit, the current quality is improved and the long service energy saving fluorescent lamp saves energy. Furthermore, the filament burnt out waste lamp tube can be used as usual.

Description

Long service energy saving fluorescent lamp

The utility model relates to a kind of lighting device, specifically a kind of long-life energy-saving fluorescent lamp.

At present the negative electrode of the fluorescent lamp that uses fluorescent tube when starting will be heated to 850-900 ℃, because be heating starting, so the easy hot melt of filament blows, thereby has shortened the useful life of fluorescent lamp.

The purpose of this utility model provides a kind of warm start with fluorescent tube and becomes cold start-up, has avoided the hot melt disintegration of filament, thereby has prolonged the useful life of fluorescent lamp.

The utility model is achieved in that as shown in Figure 1 starter 1, ballast 2, electric capacity 4 are connected on both ends of power, and fluorescent tube 3 is connected in parallel with the series circuit that electric capacity 4, starter 1 constitute.

The utility model is in start-up course, electric capacity 4 is charged to 400-500V, make the rising of the voltage between the two-stage under the fluorescent tube, when making nitrogen ionization, emitting electrons in the fluorescent tube reach the fluorescent tube starter to require, fluorescent tube is light, because do not form the loop on the filament in fluorescent tube 3 in start-up course, so filament can not be blown because of the electric current hot melt, like this, just prolonged the useful life of fluorescent tube 3.And the waste fluorescent lamp that the past filament is blown under the situation about having existed though, filament air tight at tube glass is disconnected, also can use as usual.

Operation principle is: it is perceptual that fluorescent lamp has ballast coil, and reactive power vector electric current lagging voltage 90 degree add after the electric capacity 4, capacitance current reactive power vector leading voltage 90 degree, and the two compensates mutually, has improved the transmission of electricity quality, has played the economize on electricity effect; Electric capacity 4 has been arranged in the circuit, under the situation of normal voltage 220V, made the starting resistor that is added on the fluorescent tube can reach 400-500V, thereby, make between the filament of fluorescent tube and form the electrion effect and starter, but the electric heating effect that does not produce filament loop.Because the electric heating effect of filament when not needing starter, so, as long as air tight filament still exists, no matter the waste fluorescent lamp whether filament has broken all can use in luminous continuation.

The utility model has the advantages that significantly:

1, because the utility model is added with electric capacity 4, adopt the high pressure starter to avoid electric heating discharge starter, so the attached pressure effect of fluorescent tube is strong, improved useful life, generally can increase the service life more than one times;

2, because the utility model is added with electric capacity 4, improved the quality of electric current, adopted the high pressure starter simultaneously, avoided, thereby saved electric energy with big electric heating filament starter consumed power.

Fig. 1 is an elementary diagram of the present utility model.

Embodiment of the present utility model, as shown in Figure 1, ballast 1 is 8 watts, and fluorescent tube 3 is the new fluorescent tube of 20W, and electric capacity 4 is 1 microfarad, general starter 2, through 1 year on probation, economizes on electricity about 53%; Another embodiment ballast 1 is 20 watts, and fluorescent tube 3 is that the waste and old fluorescent tube of 20W (fluorescent tube is not broken, and filament is disconnected, but filament still exists) electric capacity 4 is 1.5 microfarads, general starter.It is not remarkable that this fluorescent lamp has moved economize on electricity in 2000 hours, but brightness is suitable with the normal daylight pipe.

Claims (1)

1, a kind of long-life energy-saving fluorescent lamp that is made of starter 1, ballast 2 and fluorescent tube 3 is characterized in that starter 1, ballast 2, electric capacity 4 are connected on both ends of power, and fluorescent tube 3 is connected in parallel with the series circuit that electric capacity 4, starter 1 constitute.
