Abstract
The utility model belongs to the technical field of an electric light source. The utility model relates to a cold cathode fluorescent lamp tube for a staircase. The utility model is composed of a tube cell and an electrode head of a core post, wherein, the electrode head of the core post is not provided with an original transparent glass cover casing. The bottom of the core post forms a circular table shape and is directly connected with an end opening of the tube cell in a welding mode. The lamp tube is not provided with the glass cover casing which is not coated with fluorescent powder of an original lamp tube, nonluminous parts at both ends of the lamp tube are removed, and the luminous service efficiency of the lamp tube is improved. Simultaneously, the utility model can lead the length of the lamp tube not to be too long, and the breakage rate in transportation and carrying is reduced. The lamp tube can be used on a lighting lamp of a moving staircase or a neon lamp.
Description
The utility model belongs to the electric light source technology field, is the cathode fluorescent tube that a kind of staircase is used.
At present, the fluorescent tube of the cold-cathode fluorescence lamp that uses on the domestic escalator comprises tube cell 1 and stem stem electrode tip 2 two parts, as shown in Figure 1.These electrode tip 2 length are generally 50～100mm, its structure as shown in Figure 2, it is made of Dumet wire 3, blast pipe 4, stem stem 5, electrode 6 and cylindricality clear glass case 7, stem stem 5 is fixed with Dumet wire 3 and blast pipe 4 sealing-ins, glass case 7 bottoms and stem stem 5 bottom sealing-ins, the port burn-back of the upper port of glass case 7 and tube cell 1.Owing to be not coated with fluorescent material in the glass case, so this section glass tube is not luminous during fluorescent lamp lighting.Like this, there is the long one section fluorescent tube of 100～200mm to be luminous component not between two of series connection fluorescent tubes; Influence illuminating effect, also influence attractive in appearance.Too much not luminous component occurs for fear of the staircase fluorescent tube, people do fluorescent tube longer as far as possible, and for example 2m～2.5m is long.Fluorescent tube is long, is made troubles to transporting, carry, installing again, causes breakage easily.
The purpose of this utility model is to provide a kind of can eliminate not luminous component of fluorescent tube, thereby improves the staircase cathode fluorescent tube of fluorescent tube illumination utilance.
The staircase of the utility model design comprises tube cell and stem stem electrode tip two parts with cathode fluorescent tube, the stem stem electrode tip is made up of common Dumet wire, blast pipe, electrode and stem stem, wherein the stem stem bottom is a garden platform shape, its diameter and tube cell port diameter coupling.Stem stem and Dumet wire, blast pipe sealing-in are fixed, and electrode is welded in the Dumet wire upper end.Here saved original clear glass case, as shown in Figure 3.The garden platform shape glass and the direct sealing-in of tube cell port of stem stem bottom, as shown in Figure 4.
The staircase cathode fluorescent tube of the utility model design, owing to removed the glass case that is not coated with fluorescent material on the stem stem electrode tip, thereby eliminated the non-luminous part of fluorescent tube, make whole staircase lamp avoid inaesthetic dark space, increase the brightness of illumination of lamp, improved the utilance of fluorescent tube illumination.Because there is not luminous component in lamp tube ends, fluorescent tube can be done oversizely, can shorten fluorescent tube length, for example 1.2～1.5m etc.Like this, bring convenience for transportation, keeping, reduce the fluorescent tube breakage rate.
The lamp tube structure of the utility model design also can apply to neon lamp tube.At present, neon light tube two ends stem stem electrode tip structure and Fig. 2 are similar.Therefore, also there is a non-luminous part in its end.Often the bending of this section dark space is hidden in the luminous lamp tube back in the practicality.After using the lamp tube structure of the utility model design, also can eliminate not luminous component, reduce the troublesome poeration of two ends fluorescent tube bending, technology is simple, thereby can improve the quality of products.Here, the stem stem that needs only the stem stem electrode tip changes bead into.Because it is thinner that secondary rainbow is drawn pipe, the direct and rainbow mouth of pipe burn-back of bead portion.
Fig. 1 is an existing staircase cathode fluorescent tube structure chart.
Fig. 2 is the stem stem electrode tip structure chart of existing staircase with cathode fluorescent tube
Fig. 3 is the stem stem electrode tip structure chart of improved staircase with cathode fluorescent tube
Fig. 4 is an improved staircase cathode fluorescent tube structure chart.
Among the figure in the fluorescent tube dotted portion represent the phosphor powder layer that is coated with.Label 1 is a tube cell, and 2 is the stem stem electrode tip, and 3 is Dumet wire, and 4 is blast pipe, and 5 is stem stem, and 6 is electrode, and 7 is the glass case of stem stem electrode tip, and 8 is stem stem electrode tip and tube cell sintering place.
Embodiment according to shown in Figure 3, makes the stem stem electrode tip, and wherein the stem stem bottom is a garden platform shape, thickness 3mm, and diameter and tube cell port match, tube cell length are 1.2m.With the garden platform shape bottom burn-back of the port of tube cell and stem stem promptly.Used technology is common process.
