[0004] Many new photochemical synthesis reactions require precise control of reaction conditions, such as the wavelength of light, the size of the optical power density, and temperature, etc., while ordinary photochemical reaction equipment uses reactors and water cooling, complex devices, and continuous flow reactions cannot be achieved. The reaction conditions such as reaction temperature, wavelength, and optical power density cannot be finely controlled

[0005] Patent 202010171581.0 discloses a multifunctional continuous flow synthesis device. Although it can perform photochemical reactions, since the light source is not equipped with a heat sink in this device, the heat emitted by the lamp beads will affect the reaction temperature and affect the experimental data. Accuracy, the light source adopts DC power supply, the connection with switching power supply is more complicated, and the voltage provided is low, the optical power of the lamp bead is not high, which leads to low optical power density value, which limits the application range, and the optical power density The value is fixed, and it is impossible to explore the influence of different optical power density values ​​on the photochemical reaction catalytic effect. The wavelength of the light source is fixed, and only the photochemical reaction excited by a specific wavelength can be explored, and it is impossible to realize the unknown photochemical reaction. optimal wavelength
