Abstract

The invention relates to a control circuit for matching parameters of different LED lamp panels. The input end of an AC power supply is connected to the input end of a rectification circuit, and the input end of the rectification circuit is connected to a filter circuit. The filter circuit passes through a Flyback converter. It is connected with the luminous LED column; the output voltage sampling circuit is connected with the digital encoder through a low-pass filter; the luminous LED column is connected with the digital encoder through a signal amplification circuit, and the digital encoder is connected with a photocoupler It is connected with a digital decoder; the triangular wave generating circuit is connected with a Flyback converter through a digital decoder. The circuit of the invention avoids repeated design, shortens the development cycle and cost; reduces production control links and corresponding detection equipment, thereby greatly reducing production management costs.

Description

technical field [0001] The invention relates to the technical field of lighting driving circuits, in particular to a control circuit for matching parameters of different LED lamp panels. Background technique [0002] As the new darling of the lighting field, LED light sources are being used more and more. However, due to the lack of relatively complete industry standards and laws and regulations in China, there are many lamp product models. As a result, the parameters of the light source (LED module) and drive control circuit designed and manufactured by each company are different, and different products cannot be replaced by common ones. As a converter design company for LED control devices, customizing different products for each lighting customer increases the cost, increases the development cycle, and increases the finished product and price of the product in a disguised form, which brings great benefits to the application and promotion of LED light source products. gre...
