Problems solved by technology

However, when these tungsten-halogen quartz lamps are subject to constant bumps, vibrations, shocks during storage and transportation, or when they are subjected to unexpected shocks and vibrations during work, the glass rod brackets may shift and break away from the recesses on which they are supported. point, a drop phenomenon occurs, causing a short circuit of the filament and destroying the bulb

Embodiment Construction

[0009] The present invention is described in further detail by the following examples.

[0010] see figure 1 , figure 2 As shown, a tungsten-halogen quartz lamp with a structure to prevent the glass rod bracket from falling off is composed of a glass rod bracket 1 , a concave ring 2 , a bulb 3 , a filament 4 , a molybdenum foil 5 , and a lamp pin 6 . The glass rod support 1 is installed horizontally on the top of the inner cavity of the bulb 3, and the two molybdenum foils 5 are arranged at the lower part of the bulb 3, and the lower ends thereof are respectively connected with two lamp pins 6, and the filament 4 is stretched between the two molybdenum foils 5 and Between the glass rod brackets 1, a horizontally arranged burnt ring 2 is sprayed and burnt on the bulb 3 slightly below the glass rod bracket 1. At this time, the upper part of the bulb is gourd-shaped, and the glass rod bracket 1 is firmly supported on the burnt concave ring. Ring 2 above. This structure ensure...

Abstract

The invention discloses a structure of preventing glass bar bracket falling in the tungsten halide quartz lamp. It can make sure that the glass bar bracket can't leave the upper part of the lamp shell and fall down in any case. It increases the reliability of the filament tight structure and prolongs the operating life of the lamp. The glass bar bracket is installed levelly on the top of the lamp shell lumen. Under the glass bar bracket, the lamp shell has a circle of level burning concave circle.

Description

technical field [0001] The invention relates to the technical field of tungsten-halogen quartz lamps, in particular to a structure for preventing glass rod brackets from falling off for the tungsten-halogen quartz lamps. Background technique [0002] The existing tungsten-halogen quartz lamp is mainly composed of a bulb, a glass rod bracket, a filament, a molybdenum foil, and a lamp pin. Among them, the glass rod bracket of some tungsten-halogen quartz lamps is placed horizontally on the upper part of the inner cavity of the bulb to form a tensioned structure of the filament up and down. The filament is stretched between the upper glass rod bracket and the lower two molybdenum foils. For the tungsten-halogen quartz lamp with this structure, how to make the glass rod bracket firmly fixed on the upper part of the bulb without falling off becomes the main factor to prolong the service life of the tungsten-halogen quartz lamp. At present, the way to fix the glass rod support on...
