Halogen lamp producing technique

Abstract

The invention discloses a halogen lamp producing technique. The halogen lamp producing technique comprises the step of bulb shell production, filament production, wick production, bulb production, and assembly. In the bulb shell manufacturing technique, a quartz tube serves as the raw material, so that the product lumens are effectively improved, and the light is more definite; the quartz tube are sawed twice and repeatedly cleaned, so that the problem of tube breakage in the tube sawing process is solved; through secondary wet hydrogen shaping and hydrogen-annealed shaping after primary shaping, the hydrogen element is increased; certain oxide impurities can be removed during heating in a hydrogen environment; after tungsten filaments are heated in the hydrogen environment, atoms in the tungsten filaments become atoms with more stable lattice structures, so that the tungsten filaments cannot droop during long-term use, and accordingly, the service life of a halogen lamp is prolonged; as nitrogen which has no reaction with the material is added, the vacuum environment of the filaments is guaranteed, the service life is prolonged, and the lumen level is improved.

Description

technical field [0001] The invention belongs to the field of automobile lamp production, and more specifically, the invention relates to a halogen lamp manufacturing process. [0002] Background technique [0003] Halogen lamps are one of the lamps often used behind the headlights of automobiles. Halogen bulbs can also operate at a higher temperature than ordinary incandescent lamps, and their brightness and efficiency are also higher. However, at this temperature, ordinary glass may soften, so halogen bulbs need to use quartz glass with a higher melting point, and because quartz glass cannot block ultraviolet rays, halogen bulbs usually require an additional ultraviolet filter. The application number is 03101910.2 The invention patent of the company solves the flickering phenomenon caused by the contact between the filament and the wire parts. However, the lumen of the product is low, resulting in clearer light; the pipe is prone to rupture during the sawing process, and ...

However, at this temperature, ordinary glass may soften, so halogen bulbs need to use quartz glass with a higher melting point, and because quartz glass cannot block ultraviolet rays, halogen bulbs usually require an additional ultraviolet filter. The application number is 03101910.2 The invention patent of the company solves the flickering phenomenon caused by the contact between the filament and the wire parts. However, the lumen of the product is low, resulting in clearer light; the pipe is prone to rupture during the sawing process, and it is easy to form burrs. During the production process Some oxide impurities produced are difficult to remove; the atomic arrangement inside the tungsten wire is not tight, resulting in an unstable structure, which will sag during long-term use and have a low service life
