Ultraviolet curing device having movable reflector

摘要

An ultraviolet curing device comprising a housing having a wave guide disposed within one end thereof. Disposed within the housing and reciprocally movable between focused and unfocused positions therewithin is a reflector member which is oriented relative the light source so as to be operable to reflect ultraviolet light from the light source to the wave guide. When the reflector member is in the focused position, ultraviolet light is reflected from the light source to the wave guide in a manner facilitating the passage of a desired frequency of the ultraviolet light through the wave guide. When the reflector member is in the unfocused position, ultraviolet light is reflected from the light source to the wave guide in a manner preventing the passage of the desired frequency of the ultraviolet light through the wave guide.
