Power heat dissipation type light-emitting diode (LED) power supply

Abstract

The invention provides a power heat dissipation 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 structure is unreasonable in the prior art. The power heat dissipation 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 comprises a power box body side wall and a power box body bottom plate. A power tube is electrically connected with the circuit board and is fixedly arranged on the power box body side wall. The power box cover is in a U type and comprises a power box cover top cover and side covers which are symmetrically arranged at two ends of the top cover, a plurality of strip-shaped holes used for heat dissipation are arranged both in the top cover and the side covers, and the side covers are further provided with inserting type slotted holes which are used for drawing forth a power line. According to the power heat dissipation 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 cover is reasonable in arrangement of duty ratio, high in strength, beneficial to being processed, and low in cost.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a power dissipation type 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 existing structure of the cover of the power supply box is relatively unreasonable, which is not conducive to heat dissipation, and may also cause sundries to fall into the power supply, thereby causing problems such as short circuit of the power supply. Contents of the invention [0004] The invention provides a power heat dissipation type LED power supply, which mainly solves the problems of poor heat diss...
