Problems solved by technology

[0002] Compared with LED lights, OLED light boards currently used have the advantages of uniform light emission, close to natural light, less blue light, less heat generation, and no harm to human eyes. They are gradually replacing LED lights. Faster response time; however, there are still few drive and control devices for OLED light panels in the market, and there are no particularly clear drive parameters when using them, which may affect control operations and power consumption. It is urgent to design an optimized Promotion of OLED lighting devices

Description

technical field [0001] The OLED lighting device of the invention belongs to the technical field of OLED lighting devices. Background technique [0002] Compared with LED lights, OLED light boards currently used have the advantages of uniform light emission, close to natural light, less blue light, less heat generation, and no harm to human eyes. They are gradually replacing LED lights. Faster response time; however, there are still few drive and control devices for OLED light panels in the market, and there are no particularly clear drive parameters when using them, which may affect control operations and power consumption. It is urgent to design an optimized OLED lighting devices are promoted. Contents of the invention [0003] This solution overcomes the deficiencies in the existing technology, and the technical problem to be solved is: to provide an OLED lighting device with constant current drive and capable of stepless regulation of the OLED lamp panel; in order to s...
