Definitions

  • the present invention relates to the incandescent lamp and its components, in particular to the halogen-tungsten lamp with the improved bracket structure for fixing the luminophore.
  • the prior art various single-ended halogen-tungsten lamp is comprised of a glass shell, a filament, a glass-bead bracket, two molybdenum foils and two molybdenum pins;
  • the said glass-bead bracket doesn't contact with the glass shell, it is comprised of a glass-bead, two thick conductive wires passing through two ends of the said glass-bead and several bracket wires fixed on the said glass-bead, the middle of the said filament is supported by the said bracket wires, two ends of the filament are connected separately with two thick conductive wires of the said glass-bead bracket, and then led out an end of the said glass shell separately through the said molybdenum foils and molybdenum pins.
  • the insiders have studied and developed a kind of halogen-tungsten lamp with pole bracket structure, as indicated in Fig. 1 , the said halogen-tungsten lamp with pole bracket structure comprises a glass shell 1', a filament 3', molybdenum foils 4' and molybdenum pins 5' , the inner wall of the cavity of the glass shell 1' is linked up with a pole 2', the said filament 3' rounds through the said pole 2 ', and then connect with the molybdenum foils 4'.
  • the said halogen-tungsten lamp with pole bracket structure has solved some problems of the said halogen-tungsten lamp with glass-bead bracket structure to a certain degree, such as complicated structure etc, but still has some deficiencies: Since the up and down, left and right degree of freedom of the said tungsten filament can not be restricted, the expanding and extending tungsten filament with high temperature slides easily to close to the inner wall of the said glass shell, which can lead to blacken the inner wall of the said glass shell on the one hand, and deform the said glass shell after contacting with the incandescent tungsten filament and then reduce the resistance-to-pressure of the inner wall of the said glass shell on the other hand, in this way, the said halogen-tungsten lamp is easy to explode and reduce safety performance when it is filled with high pressure inert gases. Furthermore, it will make the said tungsten filament to depart from the optical center of the halogen-tungsten lamp and affect the photometric effect.
  • the technical problem of this invention aims to settle is that to avoid the above-mentioned disadvantages of the prior art and to provide a good safety performance halogen-tungsten lamp with simple structure and its filament which is fixed reliably and not easy to slide, and an illuminating lamp equipped with the said halogen-tungsten lamp.
  • the basic concept of the present invention is to design a hollow bracket structure to support the filament, which is not easy to slide and does not contact directly with the glass shell even when it is incandescent, expanded and extended.
  • the said hollow tube-shape bracket is a cylindrical glass tube, the said filament passes through the said glass tube.
  • the said two clamping projections hold the said glass tube from the cylindrical surface of the said glass tube.
  • the said hollow tube-shape bracket is a helix tube, the said filament passes through the said helix tube.
  • a halogen-tungsten lamp with a ring-shape bracket structure comprising a glass shell, a filament, molybdenum foils and pins, a ring-shape bracket is fixed in the cavity of the said glass shell, the said filament passes through the central hole of the said ring-shape bracket, and is then connected with the said molybdenum foils at the two ends of the said filament; the two opposite surfaces of the upper glass shell sink inwards to form two clamping projections, the said circular ring is held by the said two clamping projections.
  • the said hollow ring-shape bracket is a circular ring, the said filament passes through the said circular ring.
  • the halogen-tungsten lamp with a hollow tube-shape bracket structure of the present invention comprising a glass shell 1, a filament 3, molybdenum foils 4 and pins 5, a hollow tube-shape bracket 2 is fixed in the cavity of the said glass shell 1, the said filament 3 passes through the central hole of the said hollow tube-shape bracket 2, and is then connected with the said molybdenum foils 4 at the two ends of the said filament 3.
  • the fixation mode of the said hollow tube-shape bracket 2 is that: the two opposite surfaces of the upper glass shell 1 are clamped by the pliers after the glass shell 1 is heated, the said two opposite surfaces sink inwards to form two frustum-shape clamping projection 11, the said hollow tube-shape bracket is held by the said two clamping projections 11.
  • the said filament 3 passes through the central hole of the said hollow tube-shape bracket, the four freedom degrees of the filament 3 down and up, left and right, winding cross shaft rotation, and winding vertical shaft rotation are restricted, the two ends of the said filament 3 are clamped at the clamped position of the glass shell 1 and connected with the molybdenum foils 4, the said filament 3 can not rotate and move in the glass tube 2, so the six freedom degrees of the said filament 3 are restricted, therefore the filament 3 is fixed reliably and is not easy to slide.
  • Embodiment I as indicated in Fig. 2 , the said hollow tube-shape bracket is a cylindrical glass tube 20, the said two clamping projections 11 hold the said glass tube 20 from the cylindrical surface of both sides of the said glass tube 20, the said filament 3 passes through the said glass tube 20.
  • Embodiment II as indicated in Fig. 3 , the said hollow tube-shape bracket is a helix tube 21, the said filament 3 passes through the said helix tube 21.
  • FIG. 4 is the embodiment III of the present invention:
  • a halogen-tungsten lamp with a ring-shape bracket structure comprising a glass shell 1, a filament 3, molybdenum foils 4 and pins 5, a ring-shape bracket 22 is fixed in the cavity of the said glass shell 1, the said filament 3 passes through the central hole of the said ring-shape bracket 22, and is then connected with the said molybdenum foils 4 at the two ends of the said filament 3, the said ring-shape bracket 22 is a circular ring 22, the said filament 3 passes through the said circular ring 22, the two opposite surfaces of the upper glass shell 1 sink inwards to form two clamping projections11, the said circular ring 22 is held by the said two clamping projections 11.
  • Fig. 5 is an applicable example of the halogen-tungsten lamp on a direct-insert directional reflection lamp of the present invention.
  • the said lamp includes a reflection cup 7, the said halogen-tungsten lamp of the present invention fixed by a cement gum 8 in the optical center of the said reflection cup 7, the opening of the said reflection cup 7 is closed by a lens 6, the said halogen-tungsten lamp is fixed at the bottom of the said reflection cup by the filled cement gum 8, and the direct-insert pins 5 of the said halogen-tungsten lamp extend out the reflection cup.
  • the photometric effect and safety performance of the said direct-insert directional reflection lamps of the above-mentioned applicable example have been improved.
