Abstract

The utility model relates to a neon bulb starter for an electronic energy-saving lamp, comprising a casing and capacitors, wherein, the neon bulb LD is especially designed, is connected in parallel with the capacitors C2, and then is connected in series with the capacitors C1. Because of the change of the internal structure and the electric property of the special neon bulb, the neon bulb has a good preheating effect. The utility model has the advantages of simple circuit, stable operation, good switching characteristic, low cost, etc. The utility model can be combined with an electronic ballast circuit, and can be separately installed which is suitable for the installation mode of old style straight fluorescent lamps.

Description

The electronic energy-saving lamp neon bulb starter

The utility model is a kind of electronic energy-saving lamp neon bulb starter, and it belongs to electric ballast production technical field.

In the prior art, most of electric ballasts adopt direct starter, do not have the filament pre-heating process, cause the fluorescent tube life-span short.Some possesses the electric ballast of preheat function, cost height, low, the preheating poor performance of performance.And for example the inventor " fluorescent lamp pipeline start up by preheating electric ballast " (ZL94229663.x), it is provided with time-delay reduction voltage circuit, oscillating circuit and filament pre-heating start-up circuit, its pipeline start up by preheating better performances, cost is lower, but owing to adopt conventional Inductive ballast neon bulb starter, the scope of application is narrow, and the incompatibility industrialization is produced.

The purpose of this utility model is to provide that a kind of circuit is simple, working stability, electronic energy-saving lamp neon bulb starter that the scope of application is wide, to overcome the deficiencies in the prior art part.

Electronic energy-saving lamp neon bulb starter according to the design of this purpose comprises shell, electric capacity and neon bulb, and its architectural feature is that neon bulb LD is a tailored version, connects with capacitor C 1 after LD and capacitor C 2 parallel connections again.The cathode distance of special-purpose neon bulb LD is than the big 2-3 of about 1mm times of conventional neon bulb; The glow gases density of special-purpose neon bulb inside is higher than 2-6 times (being as the criterion with existing GB) of conventional type, to realize that starter minimum disruptive voltage＞140V and glow current are 5-25MA.

Though the profile of this starter is to commercially available similar, but because the internal structure of special-purpose neon bulb and the change of electric property, produced good pre-heat effect, comparatively ideally the current start in the fluorescent lamp luminescence process and the condition of voltage starting have been satisfied, and have that circuit is simple, working stability, switching characteristic are good, voltage is turned back curve is steep, do not have characteristics such as transit time, is suitable for promoting the requirement that the Green Lighting Project industrialization is produced.Only several maos of whole igniter circuitry element cost, it both can combine with circuit of electronic ballast, was removably installed again, to be applicable to the mounting means of old-fashioned straight tube fluorescent lamp.

Accompanying drawing 1 is the utility model one embodiment circuit diagram.

Fig. 2 is a tailored version neon bulb structural representation.

Its operation principle of combined circuit map analysis is as follows:

This starter Q circuit is as shown in the frame of broken lines among Fig. 1, and capacitor C 1, C2 are conventional film-type, and its capacity is decided according to the size of power of lamp tube and filament pre-heating electric current.When electric ballast is worked, because the conventional phase shift effect in parallel that starts capacitor C and starter Q, the off resonance of fluorescent tube YD both end voltage, its high frequency voltage effective value is lower than the fluorescent tube puncture voltage and is higher than the puncture voltage of special-purpose neon bulb LD, at this moment LD produces and punctures and the generation glow current, can be considered the pure resistance device, the connection in series-parallel phase-shift circuit that it and capacitor C, C1, C2 form makes the electric current of the filament of flowing through satisfy I _K=2.1I _HThe current preheating condition.Because big (being generally 2-4mm) that special-purpose neon bulb LD cathode distance W is conventional, bimetal leaf need when generating heat to the closing of contact can satisfy the Best Times requirement of filament pre-heating about 1 second.When the closing of contact of LD, inner glow discharge finishes, and bimetal leaf cools off rapidly, and the contact disconnects.This in a flash, because of capacitor C 2 capacity minimum (be mainly used in and regulate the high and fluorescent tube tube voltage drop height of crest factor), starter Q equals to break away from fluorescent tube YD, the capacitor C both end voltage forms resonance potential rapidly, promptly satisfies the condition of light tube electric voltage startup.

A, B connect two outputs of electric ballast among Fig. 1.

The starter minimum disruptive voltage of special-purpose neon bulb LD is high more than 10% than conventional 130V, and glow current is high more than 10 times than conventional 0.5-2MA.
