Abstract
The utility model relates to a fluorescent tube which belongs to electric light sources. Cold emission matters are coated on a filament 5, a glass bead 4 fixes two leading lines 10 of the filament, and both tail ends of the filament are integrated and are fixed to a lamp cap 1 by a soldering tin point 2. The fluorescent tube is especially suitable for light fixtures using electronic ballast as starting accessories. The fluorescent tube can be made into lamp tubes with different power and various shapes.
Description
The utility model belongs to electric light source.
Before the utility model, fluorescent tube filament (negative electrode) is a hot cathode, when it uses, and behind the first heat filament (negative electrode), could emitting electrons.Particularly in the down-hole helmet light fixture, be incandescent lamp as light source, light efficiency is low, and the life-span is short.The charged energy of user institute is limited, so incandescent lamp power is little, and luminous flux is low, so after faint light will being added on gathering, be projected on the limited working face.
The purpose of this utility model is that a kind of light efficiency height will be provided, and the helmet lamp light source that the life-span is long replaces original incandescent lamp with fluorescent tube.
The utility model fluorescent tube, at a glass tube inwall, scribble three primary colors fluorescent powder, two lead-out wire ends of two end filaments after uniting two into one, connect with a lamp driver or lamp holder.Fluorescent tube changes the cold electron emission material into by thermionic emission in use.In use, negative electrode does not need heating, can make between fluorescent tube two end negative electrodes (filament) voltage and the frequency that punctures as long as provide, and the electric current of the discharge kept is arranged, fluorescent tube just can operate as normal.It is specially adapted to electric ballast is to light a lamp in the light fixture of annex.Can make the fluorescent tube of different capacity and different shape.This fluorescent tube is made U-shaped in order to adapt to use in the helmet light fixture of down-hole with fluorescent tube, shortens fluorescent tube length, in order in small lamp, after preparation reflective mirror light is assembled, projects on the working face.
Fluorescent tube after the improvement, adopting general electric ballast is to light a lamp outside the circuit requirement of annex; Because lamp holder is the electrode of fluorescent tube, require to be installed in the airtight explosion-proof lamp type helmet light fixture, use safer.Owing to the such high temperature source of low, the no incandescent lamp filament of electronics powder, cathode temperature that adopts cold electron emission, therefore to preventing or reduce the possibility that fire damp is ignited that extremely good effect is arranged.
Description of drawings:
1 is tube lamp holder among Fig. 1,2 is the bump of lead-out wire, 3 is the clay that fluorescent tube connects with lamp holder, and 4 is the bead that two lead-out wires connect, and 5 is filament (negative electrode), 6 is globule, 7 are the three primary colors fluorescent powder that tube inner wall was coated with, and 8 is fluorescent tube, and 9 is the exhaust nozzle of fluorescent tube, 10 is two lead-out wires of filament, and 11 and 12 for adopting pins type (being a copper pin) lamp holder among Fig. 3.
The utility model fluorescent tube can be made by general fluorescent tube production technology and flow process.As long as with the triplex carbonate electronics powder of former usefulness on the filament, change the electronics powder of cold-cathode discharge lamp (mercury lamp, sodium vapor lamp) usefulness into.After making fluorescent tube, with two lead-out wire ends of fluorescent tube two end filaments (negative electrode), after uniting two into one, be connected into filament (negative electrode) extraction pole of fluorescent tube with a lamp driver or lamp holder.
Claims (2)
1, a kind of fluorescent tube comprises glass tube 8, glass tube two ends and lamp holder 1, filament 5 and filament lead wire 10, be filled with globule 6 in the glass tube, lamp holder is fixed on the glass tube with clay 3, and glass tube has an exhaust nozzle 9, scribble three primary colors fluorescent powder 7 at the glass tube inwall, it is characterized in that scribbling the pop-up material on the filament 5 two lead-out wires 10 of filament, between fixing with a bead 4, end unites two into one and is fixed on the lamp holder 1 with bump 2.
2,, it is characterized in that said lamp holder is the pin cap 11 that a copper pin 12 is arranged according to claims 1 said fluorescent tube.
