Abstract

The invention belongs to the technical field of LED switching power supplies, and particularly relates to a constant-current direct-drive type LED switching power supply, which comprises a shell; the mainboard is arranged on the inner wall of the shell through screws, and the mainboard is not in contact with the inner wall of the shell; the air inlet is formed in the top of the shell; the air outlet is formed in the bottom of the shell; the protection assembly is arranged at the top of the shell; the fan is arranged at the top of the shell, and the fan is located in the protection assembly and used for cooling a mainboard arranged in the shell; the heat dissipation assembly is arranged in the shell and is used for cooling a main board arranged in the shell; the LED switch power supply is simple in structure, and can solve the problems that a traditional LED switch power supply used outdoors is poor in waterproof and heat dissipation capability, and the heat dissipation performance of the LED switch power supply is the key for determining the service life of a product.

Description

technical field [0001] The invention belongs to the technical field of LED switching power supplies, in particular to a constant-current direct-drive LED switching power supply. Background technique [0002] The electronic devices used in LED switching power supplies are mainly: LED diodes, IGBTs and MOSFETs. SCR has a small amount of application in switching power supply input rectifier circuit and soft start circuit. GTR is difficult to drive and the switching frequency is low, so it is gradually replaced by IGBT and MOSFET. [0003] At present, the LED switching power supply for outdoor use in the market has a certain waterproof function, but most of the LED switching power supply with waterproof function use a closed casing, which leads to the poor heat dissipation ability of the traditional outdoor LED switching power supply while being waterproof, and The heat dissipation performance of LED switching power supply is the key to determine the life of the product. Theref...
