Problems solved by technology

In order to fix the stem vertically on the lamp cap, it is generally necessary to have an accurate diameter of the central through hole of the fixing seat to ensure that the stem will not be tilted after installation. This requires a tight fit between the central through hole of the fixing seat and the stem. However, the stem is made of glass. If Too much force to fit it into the through hole of the fixing seat may easily cause the stem to break

Embodiment Construction

[0010] refer to figure 1 , a lamp cap fixing structure of an LED filament stem according to the present invention, comprising a stem, a lamp cap 1 and a stem fixing seat 2 arranged in the lamp cap 1, a through slot 3 is provided in the center of the stem fixing seat 2, The slot 3 is in the shape of an hourglass, and its aperture gradually narrows from the upper and lower openings to the middle; the lower part of the stem is provided with a lower column 4 inserted into the slot 3 of the stem holder. The stem holder 2 is preferably a rubber material. This is because the rubber material has elasticity, which makes it more convenient and labor-saving when the lower column 4 is inserted into the central slot 3 of the stem holder 2. The narrow hole in the middle of the slot 3 is used to support The straight core column prevents the core column from tilting, and plays a role in supporting and fixing the core column.

[0011] The top of the lower column 4 is provided with a drive pow...

Abstract

The invention discloses a lamp cap fixing structure of an LED lamp filament and a stem. The structure comprises the stem, a lamp cap and a stem fixing base arranged in the lamp cap; a through groove hole is formed in the center of the stem fixing base and is of a sand clock shape, and the hole diameter of the groove hole is gradually reduced from an upper opening and a lower opening to the middle; and a lower vertical column inserted into the groove hole of the stem fixing base is arranged at the lower part of the stem. According to the structure, the stem fixing base is arranged in the lamp cap, the through hole of the stem fixing base is designed to be of the sand clock shape, the stem is straightened through a narrow hole in the middle of the groove hole, installation is convenient and saves labor, and the labor productivity is effectively improved.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a lamp cap fixing structure of an LED filament stem. Background technique [0002] As a green and energy-saving light source, LED lamps are widely used at home and abroad. Filament-shaped LED lamps are more popular with consumers because of their high luminous efficiency, small size, similarity to incandescent lamps, and direct and convenient replacement of incandescent lamps. The filament of the existing filament bulb lamp is generally electrically connected to the supporting wire fixed on the stem, and the stem is inserted into the fixing seat in the lamp cap for fixing. In order to fix the stem vertically on the lamp cap, it is generally necessary to have an accurate diameter of the central through hole of the fixing seat to ensure that the stem will not be tilted after installation. This requires a tight fit between the central through hole of the fixing seat and the stem. ...
