Abstract
The utility model relates to a straight filament tubular halogen tungsten lamp without support, which is suitable for particular occasions where the required voltage is low, the power density is low, a luminous body is long, the brightness is uniform, the discontinuity point does not exist and the lamp can be lighted in any model. The utility model comprises an external leading wire, a sealed molybdenum foil, an internal leading wire, a filament and a glass tube and is characterized in that a straight filament is used as the filament of the halogen tungsten lamp and is supported by an elastic device. Larger effective luminescent length can be obtained under low power input. The brightness of every part of the filament is uniform, and the filament of the lamp does not deform when the lamp works. The utility model can be lighted in any mode, such as horizontal mode or vertical modes, etc.
Description
The utility model belongs to incandescent electric light source, is used for that requirement voltage is low, power density is little, luminous element is long and brightness evenly (discontinuous point can not be arranged), and the special occasions of burning-point in any way.
The filament of existing tubular tungsten halogen lamp all is single-screw or double-spiral structure, and is wound with bracing ring on the filament, to prevent the filament distortion.Though the power density of this lamp is big, light efficiency is high, because bracing ring causes the short circuit of sub-fraction luminous element, thus discontinuous point is arranged on the luminous element, and it is yielding, burning-point in a horizontal manner.
The purpose of this utility model is by changing the structure of existing filament, to overcome above-mentioned deficiency, making it to be applicable to the needs of some special occasions.
The utility model comprises outer lead, sealing-in molybdenum foil, lead, filament, glass-tube, it is characterized in that with the filament of raw silk rings as tungsten halogen lamp, can under low-voltage, obtain bigger effective length of illumination, and the brightness of filament each several part is even with less power input.Because filament temperature influence length has obvious variation during lamp work, causes the filament distortion, and adopts the elastic device of wire coiling that filament is fixed on the center line, has offset the length variations that filament causes because of thermal expansion, has solved an above-mentioned difficult problem effectively.
The utility model has the advantages that with raw silk rings to replace the filament of taenidium that can obtain bigger effective length of illumination under less power input, the brightness of filament each several part is even, to satisfy the needs of some special purpose as tungsten halogen lamp.Adopt the elastic device anchored filament, make lamp descend filament indeformable in working order, and can level or vertically wait the any-mode burning-point.
Description of drawings:
Fig. 1 is the schematic diagram of embodiment 1.
Provide embodiment of the present utility model (is example with the 36V240W lamp) below:
The lamp length overall of present embodiment is 530mm, and the effective length of illumination of filament is 430mm.
Claims (2)
