| 摘要 |
The present invention is related to an UV LED curing apparatus, and more particularly, to a portable UV LED curing apparatus with improved illumination and timer control to solidify a UV hardening gel, such as acrylic gel. The present invention provides an UV LED curing apparatus comprising a housing and an UV LED lighting assembly enclosed in the housing. The housing is provided with a light aperture allowing UV light shone from an UV LED light source on the UV LED lighting assembly and controlled by a timer and a current regulator integrated thereon. The UV LED lighting assembly is further provided with an optical element to direct and confine UV light shine toward the light aperture of the housing, capable of providing a focused illumination and preventing leakage of UV light outside of the housing. The UV LED light source is preferably of a short wavelength such as between 360 nm and 410 nm, and the current supplied from a power supply to the UV LED light source on the substrate is preferably controlled automatically by the timer and the current regulator integrated thereon to shine UV light toward the light aperture of the housing for a prescribed period of time preferably less than 30 seconds triggered by a switch electrically connected thereto. |
