Problems solved by technology

[0003] The purpose of the present invention is to give full play to the cylindrical vitreous body provided in the middle part of the farthest tip of the filament of the SL and W-type fluorescent lamps. By placing auxiliary amalgam technology in the cylindrical vitreous body, it not only quickly improves the luminous flux, but also effectively solves the problem of when the fluorescent lamp is turned on. The serious problem of large cathode sputtering, so as to ensure the normal service life of fluorescent tubes

Embodiment 1

[0016] see figure 1 , 2 , 3, 4, figure 1 It is a schematic diagram of the existing SL type front view structure, figure 2 It is a schematic diagram of the existing SL-type top view structure, image 3 It is a schematic diagram of the existing W-shaped top view structure. Embodiment 1 of the present invention is in figure 1 , 2 3. On the basis of the existing SL-type and W-type compact fluorescent lamps, in the cylindrical glass body 3 set in the middle part of the farthest top end of the lamp tube 1 filament 2, a glass bead 5 equipped with a wire 4 is placed, and the cylindrical The vitreous body 3 is stuck with the connecting hole 9 of the lamp tube, and the wire 4 of the glass bead 5 is welded with an auxiliary amalgam 6 , which is placed in the positive column area 8 of the lamp tube 1 , and the port 7 of the cylindrical vitreous body 3 is fused and sealed. After the exhausted lamp tube is mercury-baked, the lamp is cooled, and the Au or Iu on the surface of the auxil...

Embodiment 2

[0018] Figure 5 It is a schematic diagram of the front view structure of the SL fluorescent lamp, such as Figure 5 As shown, the principle is the same as that of Embodiment 1, the difference is that the port 7 of the cylindrical glass body 3 and the glass bead 5 are directly fused and sealed.

Embodiment 3

[0020] Image 6 It is a schematic diagram of the front view structure of a W-shaped fluorescent lamp, such as Image 6 As shown, the principle is the same as in Embodiment 1, the difference is that the auxiliary amalgam 6 does not use glass beads as a carrier, but is directly welded on the wire 4, and the auxiliary amalgam is formed by the cylindrical glass body 3 arranged in the middle part of the farthest top of the filament 2. 6 is placed in the positive column area 8 of the lamp tube, and the wire 4 is directly fused and sealed with the port 7 of the cylindrical glass body 3 .

Abstract

The invention discloses a fluorescent lamp. A glass ball with a wire is placed in a cylindrical glass body arranged at a middle part at the farthest top end of a filament of an SL-type or W-type fluorescent lamp; the wire of the glass ball is welded with auxiliary amalgam; the auxiliary amalgam is arranged in a positive column region of a lamp tube; and a port of the cylindrical glass body is sealed by fusion. The cylindrical glass body arranged at the middle part at the farthest top end of the filament of the fluorescent lamp is fully utilized to place the auxiliary amalgam in the positive column region of the lamp tube, and mercury is quickly released by using an electric arc of the positive column region at the starting of the lamp tube by using the mercury absorption characteristic of the auxiliary amalgam, so the difficult starting of the lamp tube due to the low pressure of mercury steam is avoided to cause the phenomenon of large cathodic sputtering at the starting of the lamp tube is prevented, the normal service life of the fluorescent tube is further ensured and the establishment of luminous flux of the fluorescent lamp is further accelerated.

Description

technical field [0001] The invention relates to a fluorescent lamp, especially for SL type and W type fluorescent lamps with large surface load. Background technique [0002] The compact fluorescent tube adopts a bridge structure, which has a long dark area, poor firmness, and is easily damaged. Patent application number: 9530666.6 published an SL fluorescent tube, which is not only more compact than the Philips SL fluorescent tube, but also proposes a The cylindrical glass body set in the middle of the farthest tip of the filament not only solves the problem of fluorescent lamp bridging, but also greatly improves powder coating and exhaust. The appearance of this SL fluorescent tube is not only reasonable in structure, but also dark. Short area, compact structure, good firmness, less chronic air leakage and high luminous efficiency. However, following the requirements of environmental protection on the mercury content of fluorescent tubes, the disadvantages of using solid ...
