Abstract
The invention discloses a flat-spiral cold cathode fluorescent tube which is used for ordinary illumination and decorative illumination or serves as a surface light source in some special illumination. The flat-spiral cold cathode fluorescent tube comprises a glass tube, a fluorescent powder coating and cathodes, wherein the inner wall of the glass tube is coated with the fluorescent powder coating, the cathodes are packaged at the two ends of the glass tube and respectively composed of a wire and a metal electrode with getters, the metal electrodes are connected with the wires, and the wires are led out of the package positions of the two ends of the glass tube respectively. The flat-spiral cold cathode fluorescent tube is structurally characterized in that the glass tube rotates in the same direction on the same plane to form a dual-spiral shape, and the outer diameter of the spirals of the glass tube gradually decreases. The flat-spiral cold cathode fluorescent tube overcomes the defects in the prior art, and has the advantages of being more compact in structure, uniform in light emitting, higher in lighting effect, capable of facilitating matched lamp development and design and the like.
Description
Technical field
The present invention relates to a kind of cathode fluorescent tube, particularly a kind of flat spiral-shaped cold cathode, for general lighting, decorative lighting, or uses as the area source in some special lightings.
Background technology
Cold-cathode fluorescence lamp is because of without filament, has that caloric value is low, power consumption is little, the life-span is long, and the advantage such as resistance to switch activated impact, has been widely used in the every field such as illumination, decoration and demonstration especially.At present, compact fluorescent lamp with cold cathode adopts double helix cathode fluorescent tube mostly, as shown in Fig. 1, this double helix cathode fluorescent tube comprises glass-tube 11, fluorescent coating and the negative electrode being made up of seal wire 12, metal electrode and getter, fluorescent coating is coated in brokenly pipe 11 inwalls, and negative electrode is encapsulated in glass-tube 11 2 ends.Its broken pipe 11 is vertical shape spiral, and fluorescent tube height is high, and the further compactness of structure is had any problem.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the defect that prior art exists, provide a kind of more compact structure, luminous evenly, be convenient to the flat spiral-shaped cold cathode of supporting Design of Luminaires.
The present invention addresses the above problem adopted technical scheme: this flat spiral-shaped cold cathode, comprise glass-tube, fluorescent coating and negative electrode, fluorescent coating is coated in glass-tube inwall, negative electrode is encapsulated in glass-tube two ends, described negative electrode forms by seal wire with the metal electrode of getter, and metal electrode is connected with seal wire, and seal wire is drawn from the encapsulation of glass-tube two ends respectively, its design feature is: described glass-tube is double helix in a plane half with homophase rotation, and the external diameter of its spiral is gradually large.
Two ends of the glass-tube described in flat spiral-shaped cold cathode of the present invention are in spiral outer, with spiral same plane.
Two end bendings of the glass-tube described in flat spiral-shaped cold cathode of the present invention, are in spiral outer, not on spiral same plane.
The present invention compared with prior art has the following advantages: 1, the glass-tube of this flat spiral-shaped cold cathode in one plane rotates to form double helix with homophase, fluorescent tube height can be dropped to minimum, the caliber that is only a glass-tube is high, whole lamp height is reduced greatly, more compact structure.2, to be similar to face luminous for this pancake cold-cathode fluorescent class pipe, luminous evenly, light loss is little, light efficiency is higher.3, the development and Design of the convenient supporting light fixture of flat spin structure of this flat spiral-shaped cold cathode.

Specific embodiment
Embodiment 1:
Referring to Fig. 2, Fig. 3, the present embodiment flat spiral-shaped cold cathode, comprises and is coated with three base Bao Ying
The glass-tube 1 of light powder or monochromatic fluorescent material or color phosphor coating and two negative electrodes that formed by seal wire 2, metal electrode and getter.Glass-tube l is in one plane with homophase rotation, the past outward turning of a circle circle, and the external diameter of spiral is gradually large, is bent into flat Double-spiral.Two ends 3,4 of glass-tube 1 are in spiral outer, with spiral same plane.There is multiple getter can be used for cold utmost point cathode-luminescence fluorescent tube, according to the getter difference using, can adopt the multiple known maturation process such as welding, electrophoresis that getter is attached on metal electrode.Metal electrode is connected with seal wire 2.Two negative electrodes are encapsulated in respectively encapsulation place of two ends of glass-tube 1, and two seal wires 2 are drawn from two encapsulation of glass-tube l respectively.
Embodiment 2:
Referring to Fig. 4, Fig. 5, two ends 3,4 of the broken pipe 1 of the present embodiment flat spiral-shaped cold cathode are not in the helical planes of broken pipe 1.Glass-tube 1 two ends 3,4 curve certain angle, and the present embodiment is bent into vertical with the helical planes of broken pipe 1.
