The invention can not only ensure that the reactants are evenly illuminated, but also effectively control the light intensity and the temperature of the light source.

Description

technical field [0001] The invention relates to an LED light source, in particular to an annular LED catalytic light source. Background technique [0002] Photochemical reaction is a very important chemical reaction in nature, mainly involving the interaction between photons and material molecules. It has a wide range of applications in the synthesis of organic matter and the decomposition of pollutants. In photochemical reactions, the structure, wavelength and intensity of the light source have an important impact on the efficiency, yield and mechanism of chemical reactions. The light sources currently used mainly include solar simulators, mercury arc lamps, carbon arc lamps, tungsten-halogen lamps, and incandescent lamps. [0003] These light sources generally have a continuous wavelength or multi-wavelength spectrum. However, photochemical reactions often require irradiation of specific wavelengths. For example, photocatalytic reactions require photon energy to be great...

Problems solved by technology

As a result, the utilization efficiency of these light source wavelengths is generally not high, and the thermal effect is relatively obvious, requiring special heat dissipation facilities to dissipate heat for the reaction device

Although it has been reported that lasers or LEDs are also used for photochemical reactions, due to the limitations of their structures, all these light sources can only irradiate the reactant sample on one side during use, which will inevitably cause the reactant to be illuminated unevenly: from the incident direction The index of light intensity inside the reactant decreases, thus resulting in uneven reaction process and prolonged reaction time
