A constant current direct drive LED switching power supply

Abstract

The present invention relates to the field of switching power supply, specifically a constant-current direct-drive LED switching power supply, including an LED switching power supply body, a retractable structure, a sealing structure, a driving structure, a storage structure, a fixing structure, a transmission structure and a flipping structure; When overhauling and maintaining electrical components, the storage structure drives the electrical components to completely expose the LED switching power supply body, thereby making the external space larger, which facilitates the maintenance of electrical components on the storage structure from multiple directions, greatly improving the maintenance of electrical components The efficiency and quality of maintenance; furthermore, when the storage structure drives the electrical components to slide out of the LED switching power supply body, the storage structure drives the transmission structure, and the transmission structure drives the flipping structure, so that the flipping structure drives the sealing structure to separate from the LED switching power supply body to rotate, Furthermore, it is convenient to automatically control the opening and closing between the sealing structure and the main body of the LED switching power supply, and further makes the inspection and maintenance of the electrical components more convenient and quick.

Description

technical field [0001] The invention relates to the field of switching power supplies, in particular to a constant current direct drive LED switching power supply. Background technique [0002] Switching mode power supply, also known as switching power supply and switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a level of voltage into The voltage or current required by the user end, the input of the switching power supply is mostly AC power supply or DC power supply, and the output is mostly equipment that requires DC power supply, such as a personal computer, and the switching power supply performs voltage and current conversion between the two , the original power supply can be used, and on this basis, the number of modules can be flexibly increased or reduced, the current can be increased or reduced, and the utilization rate of the equipment can be improved. The power supply design adopts the N+1 mode....

Problems solved by technology

[0003] However, most of the shells of the traditional constant current direct drive LED switching power supply are spliced ​​by bolts. When the constant current direct drive LED switching power supply is overhauled and maintained, it is not convenient to quickly disassemble the constant current direct drive LED switching power supply. In addition, the bolts are easy to slip during the installation process, and the installation quality is affected when the installation is misplaced. Most of the electrical components are installed inside the casing, and the casing limits the space for inspection and maintenance, which makes the inspection and maintenance of the electrical components inside the casing not convenient and fast. And the length of the wire is fixed, it is not convenient to quickly adjust the length of the wire, so that the wire is easy to knot
