Title:
ＯＬＥＤ光源駆動制御回路及びＯＬＥＤランプ
Document Type and Number:
Japanese Patent JP7051003
Kind Code:
B2
Abstract:
The present disclosure provides an OLED light source drive control circuit and an OLED lamp. The drive control circuit includes a DC/DC constant voltage module, an external transceiver, a first internal transceiver, a microcontroller unit, a linear constant current module, and an OLED panel and a light source. The microcontroller unit communicates with the first internal transceiver, feeds back the detected output voltage to the DC/DC constant voltage module, and controls the DC/DC constant voltage module to operate. The first internal transceiver is connected with the linear constant current module through a differential bus. The linear constant current module includes a plurality of linear constant current driver ICs, each contains a second internal transceiver, and a differential bus interface of the second internal transceiver is respectively connected with a differential bus communication line connecting with a differential bus interface of the first internal transceiver. The present disclosure has a stronger anti-interference ability and effectively improves the circuit conversion efficiency of the entire drive system.
