<p>A halogen-tungsten lamp with a hollow tube-shape/ ring-shape bracket structure includes a glass shell (l), a filament (3), molybdenum foils (4) and line leads (5). The hollow tube-shape or ring-shape bracket (2) is fixed in the cavity of the glass shell (l), and the filament gets through the hole of the tube- shape or ring-shape bracket (2) and is then connected with the molybdenum foils (4) at the two ends. The two opposite faces of the upper glass shell (l) sink inwards to became two clamping projections (11) which can clamp tightly the hollow tube-shape bracket (2). The halogen-tungsten lamp has simple structure and its filament can be settled reliably to avoid the filament sliding. So it can avoid that the filament is near the inner wall of the glass shell so as that it can avoid the black-changement of the glass shell and the influence for the safety.</p> |
