Abstract

The invention discloses a high heat dissipation drive circuit module based on high-power LEDs of stage lights, which is designed in the field of LED drive circuits of stage lights, including LED drive boards, LED boards and LED power supply boards, and is electrically connected through a male seat and a female seat. Hollow holes are arranged on the LED power board, and when the LED power board, LED board and LED driver board are assembled, the LED board is embedded in the hollow holes. The invention has the advantages of compact structure, strong heat dissipation, easy installation, maintenance and replacement, anti-reversal, no need for soft boards to save costs; a high-temperature shielded power inductor is arranged between the LED power board and the load to avoid damage to the synchronous step-down circuit due to load fluctuations. The lower end faces of the LED board and the LED power supply board are flush and connected to the same heat sink, which saves the cost of the heat sink.

Description

technical field [0001] The invention relates to the field of LED driving, in particular to a high heat dissipation driving circuit module based on high-power LEDs of stage lamps. Background technique [0002] With the development of LED technology, the driving current of a single LED has increased from a few hundred milliamps to two or three thousand milliamperes, and the heat generated by the LED has also doubled; LEDs have developed from monochrome to red, green, blue, and white. The four colors are packaged together, and the heat generated per unit area is four times that of the original. LEDs require more and more output current from the drive circuit, and the heat generated by the circuit increases accordingly. [0003] In the existing large-scale LED lighting, many LEDs are connected in series, such as 4~60 LEDs, and the driving circuit outputs centralized power supply with a higher voltage. This will cause a certain volume to generate a lot of heat, and heat dissipat...
