Abstract

The invention relates to an LED driving power supply having a protection device. The LED driving power supply comprises a connection shaft, fan blades, a current sensor, a current inlet line, an analog-digital converter and a singlechip microcomputer, wherein a motor is fixed at an upper end of a protection shell, the connection shaft is fixed at a lower end of a main shaft of the motor, a lower end of the connection shaft penetrates through the protection shell and extends to the protection shell, the two fan blades are symmetrically fixed at a left end and a right end of a stirring shaft, asupport plate is arranged in the protection shell, more than two vibration-attenuation springs are arranged and are fixed on a lower end surface of the support plate at equal distance, the more than two vibration-attenuation springs are fixed at a bottom end of the protection shell, a driving power supply main body is fixed on an upper end surface of the support plate, a connection line is arranged at a left end of the driving power supply main body, and a left end of the connection line is connected with the current sensor. The LED driving power supply can be automatically disconnected, heatcan be dissipated, and vibration can be reduced.

Description

technical field [0001] The invention relates to the field of accessories for LED drive power products, in particular to an LED drive power supply with a protection device. Background technique [0002] The LED drive power supply is a power converter that converts the power supply into a specific voltage and current to drive the LED to emit light. Usually: the input of the LED drive power supply includes high-voltage power frequency AC (that is, mains), low-voltage DC, high-voltage DC, low-voltage high-voltage Frequency AC (such as the output of an electronic transformer), etc. [0003] The protection effect of the traditional LED drive power supply is poor. When it is charged, it will be burned due to excessive current, and the heat dissipation effect and shock absorption are poor. In order to solve the above problems, a LED drive power supply with a protection device is now introduced. . Contents of the invention [0004] Aiming at the deficiencies in the prior art, the...
