Abstract:
A light source apparatus includes a light source module, a light sensor, a data converter, a light source controller and a light source driver. The light source module includes a light source. The light sensor generates sensing data by sensing the amount of light generated from the light source. The data converter converts the sensing data which exceeds a maximum value of reference data of a control range into converted sensing data within the control range. The light source controller generates a control signal for controlling the amount of light from the light source based upon the sensing data corresponding to no more than the maximum value or based upon the converted sensing data. The light source driver drives the light source by providing the light source with a driving signal based upon the control signal.
