Description
Technical field
The utility model relates to a kind of cathode fluorescent tube, and particularly a kind of pancake cathode fluorescent tube is used for general lighting, decorative lighting, perhaps 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 advantage such as anti-switch activated impact has been widely used in every field such as illumination, decoration and demonstration especially.At present, compact fluorescent lamp with cold cathode adopts the double helix cathode fluorescent tube mostly, as shown in Figure 1, this double helix cathode fluorescent tube comprises glass-tube 11, fluorescent coating and the negative electrode that is made of seal wire 12, metal electrode and getter, fluorescent coating is coated in glass-tube 11 inwalls, and negative electrode is encapsulated in glass-tube 11 2 ends.Its glass-tube 11 sides found the shape spiral, fluorescent tube height height, and the further compactness of structure is had any problem.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the defective that prior art exists, provide a kind of more compact structure, luminous evenly, be convenient to the pancake cathode fluorescent tube of supporting Design of Luminaires.
The technical scheme in the invention for solving the above technical problem is: this pancake cathode fluorescent tube, comprise glass-tube, fluorescent coating and negative electrode, fluorescent coating is coated in the glass-tube inwall, negative electrode is encapsulated in glass-tube two ends, described negative electrode is made of seal wire and the metal electrode that has getter, metal electrode links to each other with seal wire, seal wire is drawn from the encapsulation of glass-tube two ends respectively, its design feature is: described glass-tube in one plane is double helix with the homophase rotation, and the external diameter of its spiral is gradually big.
Two ends of the described glass-tube of the utility model pancake cathode fluorescent tube are in the spiral outer, with the same plane of spiral.
The two ends bending of the described glass-tube of the utility model pancake cathode fluorescent tube is in the spiral outer, not on the same plane of spiral.
The utility model compared with prior art has the following advantages: 1, the glass-tube of this pancake cathode fluorescent tube in one plane forms double helix with the homophase rotation, can drop to the fluorescent tube height minimum, only be the caliber height of a glass-tube, make whole lamp height reduce more compact structure greatly.2, to be similar to face luminous for this pancake cathode fluorescent tube, 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 pancake cathode fluorescent tube.

Embodiment
Embodiment 1:
Referring to Fig. 2, Fig. 3, present embodiment pancake cathode fluorescent tube comprises glass-tube 1 that is coated with three primary colors fluorescent powder or monochromatic fluorescent material or color phosphor coating and two negative electrodes that are made of seal wire 2, metal electrode and getter.In one plane with homophase rotation, the past outward turning of a circle circle, the external diameter of spiral is gradually big, is bent into flat Double-spiral for glass-tube 1.Two ends 3,4 of glass-tube 1 are in the spiral outer, with the same plane of spiral.Have multiple getter can be used for cathode fluorescent tube, according to the getter difference of using, can adopt multiple known maturation process such as welding, electrophoresis with getter attached on the metal electrode.Metal electrode links to each other with seal wire 2.Two negative electrodes are encapsulated in encapsulation place of two ends of glass-tube 1 respectively, and two seal wires 2 are drawn from two encapsulation of glass-tube 1 respectively.
Embodiment 2:
Referring to Fig. 4, Fig. 5, two ends 3,4 of the glass-tube 1 of present embodiment pancake cathode fluorescent tube are not on the helical planes of glass-tube 1.Glass-tube 1 two ends 3,4 curve certain angle, and present embodiment is bent into vertical with the helical planes of glass-tube 1.
Other structure of present embodiment is with embodiment 1.
Claims (3)
1, a kind of pancake cathode fluorescent tube, comprise glass-tube, fluorescent coating and negative electrode, fluorescent coating is coated in the glass-tube inwall, negative electrode is encapsulated in glass-tube two ends, described negative electrode is made of seal wire and the metal electrode that has getter, and metal electrode links to each other with seal wire, and seal wire is drawn from the encapsulation of glass-tube two ends respectively, it is characterized in that: described glass-tube in one plane is double helix with the homophase rotation, and the external diameter of its spiral is gradually big.
