Abstract
A light curing unit comprising a light detecting panel positioned on the housing of the curing unit to allow the operator of the unit to visibly detect when the light is on. The panel is preferably part of the housing and is positioned proximate the light guide on the curing unit. It covers a section of the unit that exposes the light energy radiating from the lamp located in the housing of the unit. The panel is transparent or translucent, allowing the operator to see the light radiating from the lamp when the unit is in operation. If the unit is in operation and the light suddenly goes out, the operator can immediately detect that the light is out. The operator is then able to continue the curing operation with a new unit or lamp, without having to expend time using an ineffective curing unit.
