Abstract

The utility model relates to a lamp holder of a fluorescent lamp, which can be continuously utilized under the condition of filament breaking at the single end of a lamp tube of the fluorescent lamp. The lamp holder consists of an insulating shell, two connecting spring pieces, a short connecting piece and a lamp tube installing wheel, wherein a short connecting piece end button is operated to slide the short connecting piece from up to down, and the connecting spring pieces of a filament lead pin are short-connected or disconnected. Therefore, under the condition of filament breaking at the single end of the lamp tube, the short connecting piece of the lamp holder with the broken filament is closed so as to lead the current to pass through the fault filament and guarantee the circuit conduction of the lamp; and the filament at the other end transmits electrons to cause glow discharge, so the lamp tube emits light.

Description

Lamp holder

1, technical field

The utility model relates to the light fixture lamp cap device of fluorescent lamp, and it is to increase the fluorescent tube New-type lamp-holder in useful life

2, background technology

At present, the supporting light fixture of known fluorescent lamp is made up of starter, ballast, fluorescent tube, lamp bracket and lamp holder, and when the light fixture energized, fluorescent lamp sends the light of approximate daylight, after fluorescent lamp reaches useful life, and the light blackening, luminosity reduces, up to scrapping.But, in real life, owing to producing vibrations, transportation, installation make the tube filament shake disconnected, or because of new clothes fluorescent lamp wiring error, and reason such as mains fluctuations to blow the phenomenon of tube filament a lot, the fluorescent tubes that do not reach normal useful life are in a large number damaged scrap.

3, summary of the invention

According to the principle of luminosity of fluorescent lamp, behind the single-ended fracture of wire of fluorescent lamp tube, can be with its filament

Two pin wire short circuits, make whole light fixture form the loop, like this, behind the starter starter, the same preheating of the complete filament of the fluorescent tube other end and emitting electrons make the ionized inert gas in the light, and then, ultraviolet ray is sent in mercury vapour ionization in the fluorescent tube and cause glow discharge, the fluorescent material on the ultraviolet ray excited light wall and luminous.Its luminosity is the same with normal fluorescent tube with power consumption, like this, is prolonged the useful life of light greatly.But in real life, few people adopt this method to make fluorescent tube continue to use, and doing like this is that inconvenience has Danger Electric shock risk again, and ample resources has been wasted.

In order to overcome above deficiency, the utility model provides a kind of lamp holder, and shape is identical with normal lamp holder, just adds a short-circuit device in lamp holder.This lamp holder not only can under normal circumstances use, and can also make lamp circuit unimpeded behind the single-ended fracture of wire of fluorescent lamp tube, guarantees that fluorescent tube is normally luminous.

The technical scheme that this novel its technical problem of solution is taked: the utility model is to add an operating means----metal short circuit sheet in the lamp holder insulation crust, and metal short circuit sheet is a U-shaped, straddles the insulating barrier both sides, and operation terminal and short circuit sheet are fixed as one.Short circuit sheet and operation terminal are fixed on the slideway interval by insulating barrier and lamp holder bonnet, and the operation terminal stretches out the back cap surface by the bonnet slideway.The operation terminal can drive the short circuit sheet and slide up and down, and is in the lower end, inoperative under the normal condition.When the single-ended fracture of wire of fluorescent tube, fluorescent tube is just not luminous, at this moment, needn't move fluorescent tube, the short circuit sheet operation terminal of operation light fixture two ends lamp holder, slide up and down respectively, fluorescent tube filament breaking end is selected and kept the short circuit state, make lamp circuit form complete loops, like this, after the light fixture energized, voltage just can be crossed the fault filament and be added between starter movable contact spring and the static contact, makes starter produce glow discharge, and the movable contact spring heating is expanded and contacted with static contact, make electric current pass through intact end filament, single-ended filament pre-heating emitting electrons.Movable contact spring is with after static contact contacts, voltage is zero, starter stops glow discharge, the movable contact spring cooling is recovered and the disengaging static contact, in the moment that contact disconnects, this induced electromotive force is added in lamp tube ends than the high a lot of induced electromotive force of supply voltage can to produce one at the ballast two ends, and the inert gas in the fluorescent tube is ionized, cause glow discharge, along with the continuous rising of temperature in the fluorescent tube, the liquid mercury in the fluorescent tube is vaporized free, causes the mercuryvapour arc discharge and sends ultraviolet ray, the light-emitting phosphor of ultraviolet ray excited lamp tube wall, like this, single-ended fracture of wire fluorescent lamp tube just can continue to have used, thereby reaches the prolonging lamp tube purpose in useful life.

The beneficial effects of the utility model

The fluorescent lamp tube of improper aging single-ended filament can be utilized again, prolonging lamp tube useful life reduce resource consumption, reduce of the pollution of discarded fluorescent tube environment.Because this lamp holder only adds a short-circuit device on normal lamp holder, and other part of light fixture is general, simple being suitable for.
