Abstract

The utility model discloses a gas LED, which is a GLED and comprises a glass shell, a stem, an anode and a cathode. The GLED is characterized in that the anode and the cathode are respectively arranged at two ends of a glass pipe; the guide wire in the anode and the filament of the cathode are insulated with each other and are in noncoplanar perpendicularity; and the cathode is connected with the negative pole of a power supply and the anode is connected with the positive pole of the power supply. When the power supply is switched on, the cathode and the anode in the glass pipe form an anode halo discharge and hollow-cathode discharge system. When the GLED is adopted to make into a sterilamp, the ultraviolet radiation efficiency can be effectively increased; and when the GLED is adopted to make into a fluorescent lamp, the lumen and light effect can be improved.

Description

Gas light-emitting diode

Affiliated technical field

The utility model relates to a kind of LED, especially relates to a kind of gas light-emitting diode, i.e. GLED.

Background technology

Fig. 1 is the schematic diagram of Chinese patent ZL-200420058178.3 (day for announcing 2006.1.11, notification number CN2751437Y), and in the diagram: 1 is outer glass bulb, 2 is cathode filament, and 3 is the anode inner guide wire, and 4 is stem stem, 5.1 and 5.2 be the outer seal wire of negative electrode, 6 is anode seal wire outward.Proposed the mode of operation of the positive corona of gas light-emitting diode (GLED), it is characterized in that: the effective length of negative electrode and negative electrode must be greater than natural constant e to the ratio of the spacing of anode and anode corresponding size; Alleviated the problem of anode rod red heat.Because positive corona belongs to the working method of the little electric current of high voltage, is difficult to promote discharge power.

Summary of the invention

The purpose of this utility model is that a kind of GLED that contains positive corona characteristic will be provided, and can export higher-wattage and the processing procedure difficulty is lower.It comprises glass bulb, stem stem, is assemblied in the cathode filament of fluorescent tube one end, is assemblied in the anode inner guide wire of the fluorescent tube other end in addition.It is characterized in that: a cathode filament is clipped in the centre of two anode inner guide wires, anode inner guide wire and cathode filament mutually insulated, and it is vertical to present antarafacial.The diameter ratio of the width of two negative electrode inner guide wires and anode inner guide wire must be greater than natural constant e; The antarafacial spacing of cathode filament and anode inner guide wire must be greater than natural constant e with the diameter ratio of corresponding anode inner guide wire.The improvement that this is structural, the mode of operation that not only makes positive corona is converted to radial manner of the present utility model from the axial manner of Chinese patent ZL-200420058178.3, and both sides negative electrode inner guide wire and two anode inner guide wires have also been formed the hollow cathode discharge system; And in the fluorescent tube of big current work, form because anode is two inner guide wires, further solved the problem of anode dissipation; The common stem stem of more preferably existing fluorescent lamp just can satisfy the demand of this GLED processing procedure.Negative electrode in the glass bulb and anode are realized electrically connecting by seal wire and extraneous power supply: outside phase-splitting of pipe and the back of supporting two seal wires of cathode filament connect with the negative pole of power supply; Connect with the positive pole of power supply as outside phase-splitting of the pipe of two seal wires of anode and back.Glass bulb is made by saturating purple material and then is uviol lamp; Glass bulb coated inner wall fluorescent material then becomes fluorescent lamp.

Description of drawings

The utility model is described further by following accompanying drawing. Accompanying drawing 2 is structural representations of the present utility model Figure, among the figure: 1 is outer glass bulb; 2 is cathode filament; 3 is the anode inner guide wire; 4 is stem stem; 5.1 and 5.2 Be the outer seal wire of negative electrode; 6.1 and 6.2 be anode seal wire outward, 7.1 and 7.2 is the negative electrode inner guide wire. Cathode filament 2 Be clipped in the centre of two anode inner guide wires 3, anode inner guide wire 3 and cathode filament 2 mutually insulateds present antarafacial Vertically; The diameter ratio of negative electrode inner guide wire 7.1 and 7.2 width and anode inner guide wire 3 must be greater than naturally normal Number e; The antarafacial spacing of cathode filament 2 and anode inner guide wire 3 and the diameter ratio of anode inner guide wire 3 must be big In natural constant e.

Embodiment

Execution mode of the present utility model is consulted accompanying drawing 2, and in the accompanying drawing 2: 1 is outer glass bulb; 2 is cathode filament; 3 is the anode inner guide wire; 4 is stem stem; 5.1 and 5.2 be negative electrode seal wire outward; 6.1 and 6.2 be anode seal wire outward, 7.1 and 7.2 is the negative electrode inner guide wire.Cathode filament 2 is clipped in the centre of two anode inner guide wires 3, anode inner guide wire 3 and cathode filament 2 mutually insulateds, and it is vertical to present antarafacial; The diameter ratio of negative electrode inner guide wire 7.1 and 7.2 width and anode inner guide wire 3 must be greater than natural constant e; The antarafacial spacing of cathode filament 2 and anode inner guide wire 3 and the diameter ratio of anode inner guide wire 3 must be greater than natural constant e.With the outer seal wire 5.1 of the negative electrode in the accompanying drawing 2 with 5.2 mutually and the back connects with the negative pole of power supply, the outer seal wire 6.1 of anode connects with the positive pole of power supply after also mutually with 6.2, interior negative electrode and the anode of lamp just formed positive corona system and hollow cathode discharge system.

The utility model has improved the deficiency that Chinese patent ZL-200420058178.3 causes lamp lumen and light efficiency to be difficult to promote, and higher power output, lower processing procedure difficulty are arranged.
