Abstract
The utility model relates to a cold cathode fluorescent lamp comprising a lamp tube and liquid mercury in the lamp tube, which is characterized in that: two or three types of inert gas are filled in the lamp tube, and a filament in the prior lamp tube is replaced by electrodes on the two ends of the lamp tube. The utility model can realize instant starting, long service life and frequent on-off with higher brightness and better energy conservation effect, thereby being suitable for signal lamp or lighting fixture.
Description
Technical field
The utility model relates to field of light fittings, is specifically related to a kind of cold-cathode fluorescence lamp.
Background technology
In the modern society, the use of light fixture is extremely general.In various light fixtures, the characteristics that fluorescent lamp is energy-conservation with it, brightness is high, extremely people's favor is widely used in purposes such as illumination, signal.
Existing fluorescent lamp is low-pressure discharge lamp.Figure 1 shows that the structural representation of existing fluorescent lamp, it comprises a fluorescent tube 1 and a transformer (not shown).Be filled with liquid mercury and a kind of inert gas in the fluorescent tube 1, its tube wall scribbles fluorescent material.The two ends of fluorescent tube are respectively equipped with tube plug 4, are connected with transformer.Lamp tube ends also is respectively equipped with filament 2, is fixedly connected on the inner 3 of tube plug 4.During use, in the moment of power connection, the transformer two ends produce an induced voltage more much higher than supply voltage, and this voltage is added in the two ends of fluorescent lamp, make the ionized inert gas in the fluorescent tube 1 and produce self-maintained discharge.Simultaneously, inert gas carries out preheating in 2 pairs of fluorescent tubes of filament 1, and temperature raises in the fluorescent tube 1, makes the liquid mercury gasification free.Mercury vapourization and reach certain pressure after with the inert gas particle fierce collision takes place and discharge, and produce a large amount of ultraviolet rays.The fluorescent material that applies in the ultraviolet ray excited fluorescent tube 1 sends visible light.In this process,, just can make the liquid mercury gasification and reach the required pressure of starter, so existing fluorescent lamp is called hot-cathode fluorescent lamp again owing to must heat by 2 pairs of fluorescent tubes 1 of filament.
Though existing fluorescent lamp has the characteristics energy-conservation, that brightness is higher, easy to use, but still there are the following problems:
Need carry out preheating to fluorescent tube when (1) having fluorescent lamp operation now, make the liquid mercury gasification and reach certain pressure, just can make tube starting luminous,, promptly can not start moment so the individual time difference is arranged from the energized to the lamp luminescence.
(2) preheating is to realize by the filament heating power in the fluorescent tube to existing fluorescent lamp to fluorescent tube, and simultaneously, the instantaneous pressure during current lead-through can cause great impact to filament, directly influences fluorescent lifetime.Therefore, limited by filament, existing fluorescent lifetime is shorter, and can not frequent starting.
Summary of the invention
The purpose of this utility model provides a kind of new fluorescent lamp, and its start-up course does not need preheating, can start moment, and useful life is longer.
For realizing this purpose, the scheme that the utility model adopts is, is filled with liquid mercury and two to three kinds of inert gases in fluorescent tube, and lamp tube ends respectively has an electrode.
Be the better the purpose of this utility model that realizes, the inert gas in the fluorescent tube comprises xenon.
Adopt this programme, because of fluorescent tube contains two to three kinds of inert gases, Penning effect can take place when connecting in electric current, and the starting voltage of lamp tube ends is significantly reduced, the instantaneous pressure that produces during power connection is enough to make gas ionization conducting immediately in the pipe, makes fluorescent tube can realize that moment starts.Start-up course of the present utility model does not need filament pre-heating, can use electrode to replace filament of the prior art, thereby has avoided existing fluorescent tube because of disintegration of filament influences the problem in life-span, has prolonged useful life, and can frequent starting.The use of xenon in the utility model can make with the brightness of fluorescent lamp of power highlyer, has better energy-saving effect.
Description of drawings
The utility model has 2 width of cloth accompanying drawings.
Fig. 1 is the lamp tube structure schematic diagram of fluorescent lamp in the prior art;
Fig. 2 is the lamp tube structure schematic diagram of fluorescent lamp described in the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
See Fig. 2, cold-cathode fluorescence lamp described in the utility model comprises a fluorescent tube 5 and a transformer (not shown).Be respectively equipped with tube plug 8 at the two ends of fluorescent tube 5, tube plug 8 one ends stretch out outside the fluorescent tube, are connected with transformer, and the two ends tube wall that the other end passes fluorescent tube 5 is fixedlyed connected with electrode connecting line 7.Two ends are respectively equipped with electrode 6 in the fluorescent tube 5, and its two ends are fixed on the electrode connecting line 7.Be filled with liquid mercury and three kinds of inert gas argon, krypton, xenon in the fluorescent tube 5, form penning gas.
The course of work of the present utility model is as follows: electric current is connected moment, and transformer generation one is much higher than the induced voltage of supply voltage.According to Penning effect, fluorescent tube 5 of the present utility model contains three kinds of inert gases, and starting voltage is significantly reduced.Therefore, under same induced voltage, the required mercury vapor pressure of starter is lower, need not heat and can satisfy the starter requirement.This induced voltage is added between two electrodes 6 of fluorescent tube 5, can be easy to make fluorescent tube 5 starters.Behind the starter, the electric current of gas conduction can make electrode 6 keep suitable temperature, and broken hair does not penetrate electronics, simultaneously, has kept certain mercury vapor pressure in the fluorescent tube 5 yet.Because of not needing the filament heating in the utility model course of work, so be referred to as cold-cathode fluorescence lamp.
During concrete enforcement, the inert gas in the fluorescent tube 5 can be two kinds of argon, kryptons, also can charge into a certain amount of xenon in the fluorescent tube 5, to improve the brightness of fluorescent tube.
Electrode 6 of the present utility model can adopt the bar shaped laminated structure, and its two ends are separately fixed on the electrode branch line 7, also can be other different shapes, and it is electrically connected with transformer by electrode branch line 7, tube plug 8.Electrode 6 one of can adopt in ramet, nickel, the tungsten as material.Surface at electrode 6 can also scribble the electronics powder, and this electronics powder is trickle granular calcium carbonate.After being heated, it can emitting electrons help to form in the fluorescent tube gas conduction that continues.
The utlity model has moment start, the life-span is long, frequent characteristics such as switch, high brightness and energy-saving effect, is suitable as signal lamp or lighting.
