LED-based light module package including a ceramic layer and a light sensor
First Claim
1. A light module package comprising:
- at least one light emitting diode;
a mounting substrate for mounting and electrically contacting the at least one light emitting diode,a ceramic layer comprising a wavelength converting material and disposed in a path of light emitted by the light emitting diode,a light sensor disposed at the mounting substrate and having a sensitive area for detecting a luminous output of the light emitting diode whereinthe sensitive area directly faces the ceramic layer andthe ceramic layer is only partly translucent to shield the light sensor against ambient light.

Abstract
Disclosed is a light module package including a mounting substrate for mounting and electrically contacting at least one light emitting diode and a ceramic layer disposed in a path of light emitted by the light emitting diode. The ceramic layer includes a wavelength converting material and the light emitting diode is disposed between the ceramic layer and the mounting substrate. The light module package also includes a light sensor disposed at the mounting substrate for detecting a luminous output of the light emitting diode in order to control the brightness and/or the color of the light leaving the light module. The ceramic layer is only partly translucent to shield the light sensor against ambient light.
