摘要

The lamp has a plate-shaped heat extraction unit (70) with a metal mask with two through holes, a mounting plate on the unit with several LEDs (55) on its upper surface, each with an anode contact (51B) and a cathode contact (51A) arranged around the mounting plate and through holes, and two electrode pins (11A,11B) consisting of a good electrical conductor passing through the holes in the heat extraction unit and electrode holes in the plate to be connected to the anode or cathode contact of a respective LED.
