Definitions

  • CPC-Coumpound Parabolic Concentrator Compound Elliptic Concentrator (CEC-Compound), composite Hyperbolic Concentrator (CHC-Compound Hyperbolic Concentrator). That is, for example, the reflective sidewalls of the optical element are at least partially formed in the shape of at least one of said optical elements.
  • Such a small radiation entrance opening makes it possible to reduce the solid angle in which the electromagnetic radiation is emitted as close as possible to the radiation coupling-out area of the light-emitting diode chip.
  • the cross-sectional area of the beam cone emitted by the light-emitting diode chip is particularly small. This allows the construction of components with optimized etendue. That is, the highest possible radiation intensity is on one projected the smallest possible area.
  • the etendue is a conserved quantity of geometric optics. It is essentially formed by the product of the surface area of a light source and the solid angle in which the light source radiates.
  • the cooling device preferably contains at least one of the following elements: heat sink, heat-conducting material, heat pipe, thermosiphon, liquid circuit, fan.
