Embodiment 1

[0039] Embodiment 1: see figure 1 The two sets of connectors on the upper side of the PCB drive assembly 4 are arranged symmetrically along the center line of the PCB drive assembly 4. When the lamp cap 2 adopts the B22 model, the two sets of connectors on the lower side of the PCB drive assembly 4 are arranged horizontally and connected to the power terminal 1 of the lamp cap 2. connection, and realize that the AC part of the PCB drive assembly 4 is introduced into the PCB body through the embedded lead wires, so as to realize electrical conduction.

Embodiment 2

[0040] Example 2: see figure 2 The two groups of connectors on the upper side of the PCB drive assembly 4 are arranged symmetrically along the center line of the PCB drive assembly 4. When the lamp holder 2 adopts the E14, E26, E27 or E40 model, the rear part of the insulating shell 3 is provided with a screw thread that matches the lamp holder 2. Protruding circle, one set of joints on the lower side of PCB drive assembly 4 is arranged horizontally and connected to the power terminal 1 of lamp cap 2, and the other set of joints is vertically passed through the threaded protruding circle of insulating shell 3 and connected to the power terminal 1 of lamp cap 2 The metal part is locked and connected to realize electrical conduction.

Embodiment 3

[0041] Embodiment 3: When the above-mentioned lamp holder 2 adopts E14, E26, E27 or E40 models, the rear part of the insulating housing 3 is provided with a threaded raised ring that is threadedly matched with the lamp holder 2, and one group of connectors on the lower side of the PCB drive assembly 4 is horizontal Set and connect with the power terminal 1 of the lamp cap 2, another set of joints is passed through the threaded raised ring of the insulating shell 3 and wound on the threaded raised ring, the threaded raised ring of the insulating shell 3 is connected with the lamp cap 2 The metal part of the lock connection, to achieve electrical conduction.

Abstract

The invention relates to a semicircular spliced LED (Light-Emitting Diode) lamp bulb provided with an embedded driver. A positioning hole is formed in a substrate of a PCB (Printed Circuit Board) driving assembly; an insulating shell consisting of two semicircular shells is sleeved outside the PCB driving assembly; the inner walls of the semicircular shells of the insulating shell are provided with positioning columns respectively; the positioning columns are inserted into the positioning hole; the lower part of the insulating shell is connected with a lamp cap; the upper part of the insulating shell is connected with the shell; a fastening sleeve is sleeved between the upper part of the insulating shell and the shell; both sides of the PCB driving assembly are provided with two groups of joints; the two groups of joints on the upper side are inserted into the top of the insulating shell, and are welded with a light source substrate; and two groups of joints on the lower side are connected with lamp cap. Due to the adoption of the semicircular spliced LED lamp bulb, leads for electrically connecting the PCB driving assembly, the lamp cap and an LED light source board are eliminated fully, the efficiency is increased greatly, and unnecessary waste of materials and work hours is reduced.

Description

technical field [0001] The invention belongs to the technical field of LED light bulbs, and relates to a half-circle splicing type LED light bulb with built-in drive. Background technique [0002] The main structure of the existing LED light bulbs is to take the screw mounting method to put the lamp cap of the light bulb (such as B22, E27, E26, E40, etc.) Plastic heatsink connection. [0003] After connecting the lamp holder and the heat sink, connect the PCB drive assembly used to make the LED light source work with the lamp holder by soldering wires, and at the same time, use 2 leads to electrically connect the PCB drive assembly and the light source. [0004] Since the metal shell used for heat dissipation and the luminous LED light source heat sink are metal and are conductive substances, in order to ensure safety and insulation voltage, it is necessary to cover the PCB drive components stuffed into the metal or insulating shell with heat shrinkable The material of the...
