Power all-in-one type light-emitting diode (LED) power supply

Abstract

The invention provides a power all-in-one type light-emitting diode (LED) power supply which mainly solves the problems that an existing power tube is poor in heat dissipation performance and large in base pin stress, and heat conduction performance and strength are poor in the prior art. The power all-in-one type LED power supply comprises a circuit board, a power box body and a power box cover. The circuit board is fixedly arranged inside the power box body, and the power box body is in a U type or an L type and comprises a power box body side wall and a power box body bottom plate. The circuit board is fixedly arranged on the power box body bottom plate, and a power tube is connected with the circuit board in an electrical mode and is fixedly arranged on the power box body side wall. One side, far away from the circuit board, of the power box body bottom plate is attached to a mounted position completely. The power box body bottom plate and the power box body side wall form an insulating heat conduction box in an integral mode. According to the power all-in-one type LED power supply, the power tube is arranged on the power box body side wall, and not only is the heat dissipation problem solved, but also the stress problem of a base pin is solved. The power box body is an all-in-one part, heat dissipation is even, and heat conduction can be better achieved.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a power integrated LED power supply. Background technique [0002] The power tube of the existing LED power supply is generally directly installed on the circuit board, which causes the heat to be concentrated and is not conducive to heat dissipation; in order to solve this problem, the technicians adopt the setting method perpendicular to the circuit board, but this increases the stress on the pins , Long-term use is likely to cause potential safety hazards. [0003] The power supply box of the existing LED power supply is generally a split piece, which leads to low strength of the power supply box, and the heat dissipation performance of each part is inconsistent, which is not conducive to heat dissipation; at the same time, the bottom of the existing power supply box is generally not processed, resulting in power supply The bottom is not closely attached to the installed part, whi...
