Abstract
The utility model discloses a small power self-starting thermal cathode fluorescent lamp which is composed of a lamp base 1, a fluorescent tube 7, and cathodes K and K'. The cathodes are respectively connected in series with a capacitor 3, and a resistor 2 or an inductor. The cathodes K and K' are hot cathodes and are connected with an electric conduction wire 8 which is abutted with the fluorescent tube 7, wherein, the outer part of which is sheathed with an insulating transparent cover 9. The electric conduction wire 8 is arranged between the fluorescent tube 7 and the insulating transparent cover 9. The utility model can start by oneself under the action of an electric conduction filament to turn on a lamp tube. The utility model also has the advantages that structure is simple, and the utility model is started in low voltage. The lamp tube which is turned on also has the advantage that light is stably emitted by the lamp tube.
Description
The utility model relates to a kind of lighting source, especially small-power self-starting hot-cathode fluorescent lamp.
The inky light efficiency is low, and every watt of power sends the luminous flux of 3～8 lumens, is a kind of lighting source of high energy consumption.The luminous efficiency of the 3W cold-cathode fluorescence lamp that the seventies occurs is equally very low, and every watt can only be sent 5～6 lumens, and exists serious flicker.Therefore, existing incandescent lamp or fluorescent tube exist the low defective of luminous efficiency.
The small-power self-starting hot-cathode fluorescent lamp that provides a kind of luminous efficiency high is provided goal of the invention of the present utility model.
The utility model adopts the special case of following technology to realize its goal of the invention:
The utility model is made up of lamp socket 1, fluorescent tube 7, negative electrode K and K ', negative electrode respectively with electric capacity 3, resistance 2 or inductance are connected in series mutually, negative electrode K and K ' they are hot cathode, negative electrode links to each other with conductor wire 8, conductor wire 8 leans on mutually with fluorescent tube 7.
Compared with prior art, the utlity model has following advantage:
1. the utility model is made up of thermal cathode fluorescent tube and capacitance-resistance or LC ballasting circuit.The seal wire of lamp tube ends is connected in series mutually with resistance or inductance and electric capacity respectively, simultaneously by near conductive strips on the glass tube walls or silk (aluminium, copper, silver, nickel or alloy etc.), so have the function of auxiliary build-up of luminance.Particularly select for use resistance wire or resistance to bring substitutional resistance, then more help lamp lighting-up to light.Under the effect of a supply voltage, conductive strips (or silk) form a stronger electric field near filament, cause this place's gas ionization discharge, whole then fluorescent tube discharge conducting.
2. the utlity model has simple and reliable for structurely, easy to use, the fluorescent tube firing voltage is low, and operating current is stable, and the electric capacity power consumption is few, has reduced the reactive loss to electrical network simultaneously.Its luminous efficiency is 3～4 times with the incandescent lamp of power or cold-cathode fluorescence lamp.Flicker when it is luminous is far below cold-cathode fluorescence lamp.Present technique is specially adapted to 1～5 watt small-power fluorescent lamp.
3. the utility model is placed on fluorescent tube with resistive film or conductor wire, has simplified making of the present utility model, particularly be placed on the insulation diffuser after, make the utility model both have and make simple advantage to have safe and reliable advantage again.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an example structure schematic diagram of the present utility model.
Fig. 3 is another example structure schematic diagram of the present utility model.
With reference to the accompanying drawings embodiment of the present utility model being done one describes in detail:
The utility model is by lamp socket 1, fluorescent tube 7, negative electrode K and K ' form, negative electrode respectively with electric capacity 3, resistance 2 or inductance are connected in series mutually, negative electrode K and K ' are hot cathode, negative electrode links to each other with conductor wire 8, conductor wire 8 leans on mutually with fluorescent tube 7, above-mentioned fluorescent tube 7 adopts halogen-phosphate fluorescent material to make, also can adopt fluorescent RE powder to make, hot cathode can adopt the tungsten filament that scribbles the electronics powder to make, be fixed on the two ends of fluorescent tube by fixed head 5 and 6, conductor wire can adopt graphite, conductive paint, aluminium, tin or alloy conductive film, also can adopt steel, iron, wires such as nickel, conductor wire 8 of the present utility model is close to fluorescent tube 7, and the outer cover of fluorescent tube 7 is provided with insulation diffuser 9, conductor wire 8 is located between fluorescent tube 7 and the insulation diffuser 9, the utility model can constitute the metalfilmresistor band with resistance 2 and conductor wire 8, or resistance 2 and conductor wire 8 are constituted resistance wire, promptly replaces resistance and conductor wire with resistance film band or resistance wire.The resistance of above-mentioned resistance 2 can be selected in 20～100 Ω, and ballast electric capacity can be selected 0.47～4 μ f.
