Embodiment Construction
[0011] Embodiments of the present invention: the structure of the present invention is as figure 1 As shown in Fig. 2, the lamp tube 1 is a quartz glass tube, and the two ends of the lamp tube 1 are respectively assembled and connected with a ceramic head 3, and the silk feet at the two ends of the filament 2 are respectively welded on the molybdenum sheet 4, and the present invention shortens the length of the filament 2 length and the length of the corresponding lamp tube 1, and the middle section of the filament 2 is wound into a filament in the form of a double helix (that is, the double helix filament 5), and this region is the main light-emitting area of the halogen lamp tube. The width D of the spiral filament 5 is 1 / 8 to 1 / 6 of the total length L of the halogen lamp tube; when the lamp tube 1 is sealed, the shortened lamp tube 1 is filled with halogen gas so that the air pressure in the lamp tube 1 is 2 ~3 standard atmospheric pressure; then use the method of increas...
