Problems solved by technology

[0002] The traditional welding method is to use high-temperature manual welding to achieve the effect of fixing the filament, making the welding temperature uncontrollable, prone to virtual welding, and easy to damage the LED filament. Therefore, the demand for solder-free LED filament bulbs is necessary. , the current solder-free LED filament bulbs have the following defects:
[0003] The existing improvement method is to connect the filament to the stem with the help of a fixture to achieve the purpose of avoiding welding. However, there are bumps in the transportation process of the LED lamp and the installation process of the lamp, which leads to the spot connection inside the lamp. The filament is offset from the stem, or even falls off

Embodiment

[0025] see Figure 1-Figure 6 , the present invention provides a solder-free LED filament bulb lamp, the structure of which includes a lampshade 1, a stem 2, and a mounting plate 3, the lampshade 1 is connected to the mounting plate 3, the stem 2 is arranged inside the lampshade 1, The lampshade 1 is set up in a bulb shape, the stem 2 is fixedly connected with the mounting plate 3, and the mounting plate 3 is set up in a spiral shape.

[0026] The stem 2 is composed of a filament fixing cavity 201, a working cavity 202, a connecting mechanism 203, a fixing mechanism 204, and a filament 205. The filament fixing cavity 201 is provided with two and set up in a symmetrical structure. The cavity 201 is installed in the working cavity 202, the connecting mechanism 203 and the fixing mechanism 204 are both arranged in the filament fixing cavity 201, the connecting mechanism 203 is located in the north direction of the fixing mechanism 204, and the filament 205 and the connecting mech...

Abstract

The invention discloses a welding-free LED filament bulb, structurally comprising a lampshade, a core post, and a mounting disc. The lampshade is connected with the mounting disc; the core post is arranged inside the lampshade; the lampshade is in bulb form; the core post is fixedly connected with the mounting disc; the mounting disc is in spiral form. The welding-free LED filament bulb has the advantages that upon insertion of a filament, two clamp plates are forced manually and are opened oppositely, a spring gains elastic potential energy when contracted upon force, the two clamp plates move to each other and clamp the filament after external force is removed, and the filament can be tightly connected with a conductive block; under traction of a wire fitting ring and action of compression, the filament is wound the lateral side of a screw shaft wheel along with its rotation and is press-fitted by the aid of a presser plate, loosening of the filament is avoided, and reinforcing is achieved.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to a welding-free LED filament bulb lamp. Background technique [0002] The traditional welding method is to use high-temperature manual welding to achieve the effect of fixing the filament, making the welding temperature uncontrollable, prone to virtual welding, and easy to damage the LED filament. Therefore, the demand for solder-free LED filament bulbs is necessary. , the current solder-free LED filament bulbs have the following defects: [0003] The existing improvement method is to connect the filament to the stem with the help of a fixture to achieve the purpose of avoiding welding. However, there are bumps in the transportation process of the LED lamp and the installation process of the lamp, which leads to the spot connection inside the lamp. The filament is offset from the stem, or even falls off. Contents of the invention [0004] Aiming at the deficiencies of the prior art, t...
