Abstract
A heat sink, lighting device and method of manufacture are described. A heat sink includes at least one sheet metal having a first surface and a second surface, at least one first reference pin extending at least in part from the first surface, and at least one second reference pin extending at least in part from the second surface and located within a diameter of, and concentrically with, the at least one first reference pin. The diameter of the at least one first reference pin being larger than a diameter of the at least one second reference pin.
Claims16
A heat sink comprising:
- at least one sheet metal having a first surface and a second surface;
- at least one first reference pin extending at least in part from the first surface;
- and
- at least one second reference pin extending at least in part, from the second surface and located within a diameter of, and concentrically with, the at least one first reference pin, the diameter of the at least one first reference pin being larger than a diameter of the at least one second reference pin.
A lighting device comprising:
- at least one heat sink comprising:
- at least one sheet metal having a first surface and a second surface,
- at least one first reference pin extending at least in part from the first surface, and
- at least one second reference pin extending at least in part from the second surface and located within a diameter of, and concentrically with, the at least one first reference pin, the diameter of the at least one first reference pin being larger than a diameter of the at least one second reference pin;
- and
- at least one lighting module mounted to at least one receiving section of the at least one heat sink.
A method manufacturing a lighting device, the method comprising:
- providing at least one sheet metal to form a heat sink;
- forming at least one first reference pin into the at least one sheet metal by deep drawing, in a first direction, the at least one first reference pin from the at least one sheet metal on a first surface;
- forming at least one second reference pin into the at least one sheet metal by deep drawing, in a second direction opposite the first direction, the at least one second reference pin from a second side of the at least one reference pin;
- providing at least one lighting module);
- and
- arranging the at least one lighting module in at least one receiving section of the heat sink.
