Abstract

A light curing apparatus including a carrier device and a light source with a lamp. The light curing apparatus also includes a light intensity detection device, a data processing unit and a display unit. The light intensity detection device is configured for detecting the intensity of the light source and outputting a light intensity value, the data processing unit is configured for receiving the light intensity value and forming and outputting a data signal of the changed curve of light intensity with the time change, the display unit is configured for receiving the output of the data processing unit and displaying the curve of the light intensity with the time change. The light curing apparatus can detect the actual light intensity of the light source, such that the light curing time can be changed accordingly.

Claims
