摘要:
The present invention relates to a light-emitting diode (LED) module (10) comprising a first LED chip (12) for emitting light of a first color, a LED element (14) comprising a second LED chip, which element is placed alongside the first LED chip and adapted to emit light of a second color, and a ceramic conversion plate (16). The ceramic conversion plate covers only a portion of the first LED chip and comprises a wavelength-converting material for converting light emitted from the first LED chip to a third wavelength. The size of the portion of the first LED chip that is covered by the ceramic conversion plate is selected so that the LED module produces mixed light of a certain desired color The present invention also relates to a method of manufacturing such a LED module.

摘要:
An imaging system for imaging an object onto an image sensor, and which has a front side facing the object and a rear side facing away from the object, the rear side being arranged behind the front side as viewed from the object. Furthermore, the imaging system has a light entrance device at the front side through which light coming from the object can enter into the imaging system. In this case, the light traverses the beam path between object and image sensor. At least one first and one second optical element are likewise present and are arranged at the rear side in such a way that they can influence the beam path. The light entrance device has an electrically switchable liquid crystal element which deflects the beam path at at least one first angle and a second angle which is different from the first angle depending on the electrical switching state. A discretely switchable focal length change is realized by this electrically effected change in the beam path.

A composite multi-color light emitting diode device includes a first light emitting diode unit and a second light emitting diode unit that is arranged on top of the first light emitting diode unit for emitting two different wavelengths of electromagnetic radiation. A third light emitting diode unit may be arranged on top of the second light emitting diode unit, thereby providing a stack of three light emitting diode units. Alternatively, the third light emitting diode unit may be arranged on the first light emitting diode unit, thereby providing two light emitting diode units side-by-side on top of the first light emitting diode unit.
