UV-LED-LIGHT SOURCE

摘要

The invention relates to a LED-light source comprising a UV-LED embedded in a reflector housing and optionally covered by a transparent material, wherein the reflector housing is made of a polymeric material comprising (A) a semi-crystalline aliphatic polyamide (PA),obtained from aliphatic diamines and aliphatic dicarboxylic acids, and optionally other monomeric building blocks in an amount of at most 10 mole %, relative to the total molar amount of monomeric building blocks in the polyamide, and (B) a UV-reflecting pigment or filler. The invention also relates to a water purification device comprising the LED-light source. The invention also relates to a lighting armature comprising a mixing chamber comprising multiple UV-LEDs embedded in a reflector housing and optionally covered by a transparent material, wherein the mixing chamber comprises a reflection wall, at least part thereof made of a polymeric material as mentioned hereabove.
