Title:
ULTRAVIOLET CURING DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/227945
Kind Code:
A1
Abstract:
An ultraviolet curing device and a control method therefor. The device comprises an ultraviolet light source and a controller connected by means of a cable. The ultraviolet light source is a water-cooled ultraviolet light source or an air-cooled ultraviolet light source. The controller is provided inside or outside of the ultraviolet light source. The ultraviolet light source comprises a shell (101), a copper substrate (103), a multi-path LED chip (104), and a cooling assembly. The controller comprises a constant-current circuit board (105). The constant-current circuit board (105) performs multi-path constant-current control on the multi-path LED chip (104) to monitor anomaly of the pressure drop of the multi-path LED chip (104), thereby achieving control of the multi-path LED chip (104).
