Claim 6:
7. A method for manufacturing a hermetically sealed LED light, comprising:
providing a metal cap having an end face at one end, an opening at an opposite end, a hollow channel therebetween, and a peripheral depression at the opposite end of the metal cap;
melting a glass into the metal cap at the opening to form a hermetically sealed window in the opening, the window having a lenticular shape due to surface tension of the glass that does not protrude beyond the opposite end of the metal cap;
providing a base made of a ceramic material;
disposing an LED chip on an upper surface of the base;
arranging the metal cap with respect to the base so that the base is not arranged within the hollow channel but is mounted to the end face of the metal cap with the LED chip in the hollow channel; and
soldering, with a solder, an outer edge of the end face and the upper surface of the base to one another to hermetically seal the metal cap and the base to one another.
