摘要

The light source (30) has multiple chips (56), where each chip has light emitting diode (LED). The LED carrier has a metallic core and the upper surface is connected with a circuit layer and the chips are connected with the circuit layer. A cover (40) is connected with the LED carrier, where the cover has an opening (42) by which the light of LED is emitted. A cupola-shaped encapsulating layer is present on each chip and the encapsulating layer is placed at a distance from the sides of opening in such a manner that an air gap lies between the encapsulating layers and the sides.
