Optical microfluidic devices are important reactors for photochemical production. Their principle is to use light to illuminate the reactive fluids flowing through the optical microfluidic device, causing a photocatalytic reaction.

[0003] However, traditional photocatalytic reactions mostly use light sources such as mercury lamps or xenon lamps, which release a lot of heat, have inaccurate light waves, and the wavelengths of the light sources are relatively complex, resulting in many side reactions, poor selectivity, high energy consumption, and the leakage of mercury in mercury lamps can easily cause secondary pollution.

[0004] Therefore, those skilled in the art provide a light control device and an optical microfluidic device to solve the problems raised in the above background technology. Summary of the Invention

Compared with existing traditional light-microfluidic devices, the light-emitting component of this light-microfluidic device is an LED lamp array board, which has the advantages of ultra-strong illumination, adjustable power, and replaceable light sources. It makes the process of photocatalytic degradation of pollutants safer, energy-saving and environmentally friendly, and can treat a larger amount of pollutants.

[0018] Furthermore, a fixing frame is fixedly connected to the middle of the inner wall of the protective shell, and a chamber is opened on one side of the outer side of the fixing frame.
