摘要

Light emitting diode arrangement comprises a substrate (200), a light emitting chip (210) arranged on the substrate for emitting light, a sleeve (220) for encasing the chip and a photoluminescent material (230) distributed in the sleeve. An independent claim is also included for a cold cathode fluorescent lamp comprising a light tube, a discharge gas filling the tube, a photoluminescent material applied on the inner wall of the tube and an electrode set consisting of an anode and cathode.
