Halogen bulb provided with double layers of glass bodies

Abstract

The invention relates to a halogen bulb provided with double layers of glass bodies. The halogen bulb comprises an inner-layer glass bulb, a filament, a glass clamping plate, a filament connecting piece and a connecting wire, wherein the filament is arranged in the inner-layer glass bulb and connected with the glass clamping plate, and the filament connecting piece is arranged in the glass clamping plate and connected with the connecting wire extending out of the glass clamping plate; the inner-layer glass bulb, the glass clamping plate and the connecting wire are arranged in an outer-layer glass bulb, a lamp holder is arranged at one end of the outer-layer glass bulb, the other end is closed, the connecting wire is connected with the lamp holder, so that the filament and the lamp holder are electrically connected; a clamping plate bracket is further arranged on the glass clamping plate, the clamping plate bracket and a lamp holder glass column are connected and fix the glass clamping plate and the inner-layer glass bulb in the outer-layer glass bulb, and the lamp holder can adopt a screwed or bayonet holder. The halogen bulb adopts the double-layer glass casing structure, can adapt to various lamp holder connecting modes, is safer and more reliable to use and saves more energy, the bulb is more convenient to mount or replace, and the service life of the bulb is prolonged.

Description

technical field [0001] The invention relates to a halogen light source, in particular to a halogen bulb with a double-layer glass shell. Background technique [0002] At present, the existing halogen bulbs on the market generally include a glass shell, a filament, a glass splint, a filament connecting piece, a connecting wire and a lamp pin. And it is connected with the connecting wire protruding from the glass splint, and the connecting wire is connected with the lamp pin. When in use, the lamp pins are usually connected to the lamp holder with a plug-in structure. When installing or replacing a light bulb, it is necessary to directly grasp the glass shell. Because there is a high pressure inside this type of light bulb, and the glass shell will generate high temperature after the light bulb is powered on. The temperature immediately drops behind the lamp, which will cause the halogen bulb to be easily damaged by external force during installation or use, and even cause th...

Problems solved by technology

When in use, the lamp pins are usually connected to the lamp socket with a plug-in structure. When installing or replacing the bulb, it is necessary to directly grasp the glass shell. Because there is a high pressure in this type of bulb, and the glass shell will generate high temperature after the bulb is powered on, shutting it down The temperature drops immediately behind the lamp, which will cause the halogen bulb to be easily damaged by external force during installation or use, and even cause the glass shell to break, endangering personal safety; Smaller and often not usable on lamp heads with threaded or bayonet mounts
