Description

Technical Field

[0001] The utility model relates to an improved structure of a halogen lamp, especially a halogen lamp used as a heat source for semiconductor heat treatment, or for annealing treatment, drying treatment, heating treatment, etc. of various workpieces. Background Art

[0002] At present, the existing halogen lamps on the market, such as Figure 3 As shown, when the halogen lamp 100 is installed, a coil-shaped filament 102 arranged in the axial direction is disposed in a horizontal glass envelope 101, a pair of long and short power supply rods 103, 104 for electrically connecting and supporting the front end and the rear end of the filament 102, a main support rod 105 for supporting the middle part of the filament 102 in a horizontal posture when the halogen lamp 100 is installed from above, and first and second auxiliary support rods 106, 107.

[0003] Since the coil-shaped filament 102 of the above-mentioned existing halogen lamp 100 is relatively long, the number of turns of the filament 102 is 9 turns or more, and the supporting force of the filament 102 on the auxiliary support rods 106, 107 is uneven. Due to the repeated lighting, turning off of the lamp or the rise and fall of power supply of the halogen lamp 100, the resulting thermal stress causes the filament 102 to drop severely, so there is a concern of touching the auxiliary support rods 106, 107 and causing a short circuit, thus affecting the service life of the halogen lamp 100.

[0004] In addition, the main support rod 105 and the auxiliary support rods 106, 107 of the above-mentioned existing halogen lamp 100 are respectively designed on both sides of the filament 102. When the filament 102 is deformed due to dropping, it is easy to touch the auxiliary support rods 106, 107 and cause a short circuit phenomenon.

[0005] In view of the above-mentioned disadvantages and deficiencies of the existing halogen lamp, the utility model provides an innovative structure of a halogen lamp, which designs the number of turns of the filament of the halogen lamp to be 8.5 turns, so that the force on the support rod of the filament is more uniform, and the filament is less likely to be flexed and deformed; in addition, all the multiple support rods of the halogen lamp are arranged on the same side of the filament. The halogen lamp designed in this way can avoid the short circuit phenomenon caused by the filament touching the support rod due to dropping. Summary of the Utility Model

[0006] To achieve the above object, the utility model adopts the following technical means:

[0007] An improved structure of a halogen lamp. The halogen lamp is installed as a horizontal glass envelope, and a coiled filament is arranged along the axial direction inside the glass envelope. The front and rear ends of the filament are electrically connected to a power supply rod respectively. The front power supply rod is inserted and supported in the fused lower part of the glass envelope, and the rear power supply rod is connected and supported in the sealed part of the glass envelope.

[0008] The number of turns of the coiled filament is designed to be 8.5 turns, and all the multiple support rods for supporting the filament are arranged on the same side of the filament.

[0009] The beneficial effects of the present utility model are as follows:

[0010] By designing the number of turns of the filament of the halogen lamp in the present utility model to be 8.5 turns, the force on the filament on the support rod is relatively uniform, and the filament is less likely to be bent and deformed. In addition, all the multiple support rods of the halogen lamp are arranged on the same side of the filament. The halogen lamp designed in this way can avoid the short-circuit phenomenon caused by the filament touching the support rod due to dropping. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Please refer to Figure 1 and Figure 2 , the present utility model provides an improved structure of a halogen lamp. The halogen lamp 10 is installed as a horizontally arranged glass envelope 20 made of quartz glass. A coiled filament 30 is arranged along the axial direction thereof inside the glass envelope 20. The front end of the filament 30 is electrically connected to a pole 31 for power supply, and the pole 31 is inserted and supported in the fused lower part (tip-off) 21 at the front end of the glass envelope 20; the rear end of the filament 30 is electrically connected to another pole 32 for power supply, and the pole 32 is connected and supported at the sealed part 22 of the glass envelope 20.

[0031] The main features of the halogen lamp 10 of the present utility model are as follows: the number of turns of the coiled filament 30 is designed to be 8.5 turns (the number of turns of the filament of the existing halogen lamp is 9 turns or more than 9 turns); in addition, all of the multiple support poles 33, 34, 35 for supporting the filament 30 are designed at the same side position of the filament 30 (the long and short support poles of the existing halogen lamp are respectively designed on both sides of the filament); in addition, hook-shaped glands 331, 341, 351 for hooking the filament 30 are respectively installed at the front ends of the above support poles 33, 34, 35.

[0032] It can be seen from the above structural design that the present utility model has the following advantages:

[0033] 1. The number of turns of the filament 30 is designed to be 8.5 turns, which can make the force on the filament 30 more uniform when it is fixed by the support poles 33, 34, 35. When the halogen lamp 10 is continuously lit and turned off, the situation of the filament 30 sagging and deforming downward is less, so the possibility of short circuit can be avoided.

[0034] 2. All of the multiple support poles 33, 34, 35 for supporting the filament 30 are arranged on the same side of the filament 30 (i.e., above the filament 30), which can avoid the filament 30 touching the support poles 33, 34, 35 after sagging and deforming when the halogen lamp 10 is continuously lit and turned off, thus preventing short circuit phenomena.

[0035] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model by using the disclosed technical content. However, as long as it does not depart from the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
