The utility model has the advantages of compact structure, practical appearance and convenient application. It can be used to design compact and compact lighting decorations, and at the same time make the lighting decorations have higher brightness.

Description

compact fluorescent tube

The utility model relates to lighting equipment, in particular to a compact fluorescent lamp tube.

Fluorescent tubes are widely used in daily life, but they also have the disadvantages of being large and inconvenient to design and produce compact lighting.

The purpose of the utility model is to provide a compact fluorescent tube with compact structure, practical and beautiful appearance.

In order to achieve the above purpose, the utility model adopts the following measures: the compact fluorescent tube has double helical fluorescent tubes connected in parallel and in series, and the cathodes of the fluorescent tubes are arranged at both ends.

The utility model has the advantages of compact structure, practical appearance and convenient application. It can be used to design compact and small lighting decorations, and at the same time make the lighting decorations have high brightness.

Describe in detail below in conjunction with accompanying drawing:

Fig. 1 is a schematic diagram of the structure of double-helix C-shaped fluorescent lamps connected in series;

Fig. 2 is a schematic structural diagram of double-helix S-shaped fluorescent lamps connected in series;

Fig. 3 is a schematic diagram of the structure of double-helix inverted S-shaped fluorescent tubes connected in parallel and in series.

The compact fluorescent tube has double helical fluorescent tubes 3 connected in parallel and in series, and fluorescent tube cathodes 1 and 2 are arranged at both ends. Parallel series connection of double helix fluorescent tubes is planar. The double-helix fluorescent lamps connected in parallel and in series are the double-helix C-shaped fluorescent lamps connected in parallel and in series, the double-helix S-shaped fluorescent lamps connected in parallel and in series, or the double-helix reverse S-shaped fluorescent lamps connected in parallel and in series.

As shown in Figure 1, the lamp tube is composed of left and right parts. The left part is a clockwise outward spiral structure with cathode 1 end (generally cathode, stem, guide wire, etc.), and the right part is a cathode with 2 ends. The counterclockwise outward spiral structure forms a C shape.

As shown in Figure 2, the lamp tube is composed of two parts, the left part is a counterclockwise outward spiral structure from the cathode 1 end, and the right part is an S-shaped anticlockwise outward spiral structure from the cathode 2 end.

As shown in Figure 3, the lamp tube is composed of left and right parts. The left part is a clockwise outward spiral structure from the cathode 1 end, and the right part is a clockwise outward spiral structure from the cathode 2 end, forming a reverse S shape. .

The main part of the lamp tube with the above structure can be designed into a plane shape (the two ends of the cathode 1.2 can be designed in the plane or beyond the plane); curved surface shape. The above-mentioned "spiral" is not necessarily a combination of garden arcs and garden arcs, but can also be a combination of other types of curves and line segments. In addition, in order to reflect compactness, the spiral should exceed at least 360 degrees.
