    摘要: 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.

    摘要: A white light LED is described that uses an LED die that emits visible blue light in a wavelength range of about 450-470 nm. A red phosphor or quantum dot material converts some of the blue light to a visible red light having a peak wavelength between about 605-625 nm with a full-width-half-maximum (FWHM) less than 80 nm. A green phosphor or quantum dot material converts some of the blue light to a green light having a FWHM greater than 40 nm, wherein the combination of the blue light, red light, and green light produces a white light providing a color rendering of Ra,8>90 and a color temperature of between 2500K-5000K. Preferably, the red and green converting material do not saturate with an LED die output of 100 W/cm2 and can reliably operate with an LED die junction temperature over 100 degrees C.
