Slow-start photocuring device and switch control module thereof

A slow-start photocuring device, comprising:

• a housing having an inner side provided with an internal cavity, wherein the inner side of the housing is further provided with one or a plurality of openings on one or two sides of the internal cavity;
• an ultraviolet (UV) light-emitting diode (LED) module comprising a plurality of UV LED units provided around the internal cavity, wherein the UV LED units are of different wavelengths, and the UV LED units have a light-emitting side facing the internal cavity;
• and
• a switch control module connected to the UV LED module, wherein the switch control module includes a signal modulator, the signal modulator activates a buffer mode when receiving a trigger signal, and the UV LED module in the buffer mode instructs the UV LED units of different wavelengths to output light of a plurality of brightness levels separately and sequentially according to an output signal of the signal modulator, and after a period of time executing the buffer mode, the switch control module activates an ordinary mode to drive the UV LED module steady in a stable wavelength.
