Abstract
A multi-component LED lamp is disclosed herein. The multi-component LED lamp comprises an outer case housing with at least one heat sink and an array of LEDs disposed therein. The outer case comprises a plurality of vent openings and a light projecting end. The array of LEDs is disposed proximate the light projecting end in the outer case. Each heat sink disposed in the outer case is a separate component part of the LED lamp. The vent openings and heat sink(s) are disposed and configured to provide convective air flow pathways through the multi-component LED lamp and remove heat therefrom.
Claims17
A multi-component LED lamp comprising:
- an outer case configured to house a first heat sink and an array of LEDs;
- said outer case comprising a plurality of vent openings and terminating with a light projecting end;
- an array of LEDs disposed proximate said light projecting end of said outer case;
- a first heat sink disposed in said outer case;
- said first heat sink and said outer case being separate component parts of said LED lamp;
- said first heat sink comprising an outer peripheral portion disposed in continuous contact with an entire inner perimeter of said outer case;
- said outer peripheral portion of said first heat sink being configured and disposed to provide conductive heat transfer between said outer case and said first heat sink, continuously throughout said outer peripheral portion of said first heat sink and having a plurality of vent openings disposed proximate said outer case in flow communication with air flowing through said outer case;
- said first heat sink comprising an inner first frustoconical portion extending inwardly from said outer peripheral portion and having a larger diameter proximate said light projecting end of said outer case;
- and
- said inner portion of said first heat sink being configured and disposed to provide convective heat transfer to air flowing thereabout and through said plurality of vent openings in said outer case and said light projecting end of said outer case.
An LED lamp comprising:
- an outer case with at least one vent opening and terminating with a light opening;
- a heat sink having an outer peripheral portion disposed in continuous contact with an entire inner perimeter of said outer case, proximate said light opening, and comprising a first frustoconical portion extending away from said light opening, said heat sink being a separate component part of said LED lamp;
- an inner portion of said heat sink comprising a second frustoconical portion extending from a terminal end of said first frustoconical portion and toward said light opening;
- and
- said outer case and said heat sink being configured and disposed to provide convective heat transfer to air flowing between portions thereof.
A multi-component LED lamp comprising:
- an outer case comprising a plurality of vent openings and configured to dispose at least one heat sink and a plurality of LEDs;
- at least one heat sink disposed in said outer case configured to conduct heat away from said plurality of LEDs and to convect heat to air flowing through said plurality of vent openings in said outer case;
- and
- said at least one heat sink comprising an outer peripheral portion in continuous contact with an entire inner perimeter of said outer case, a plurality of vent openings disposed proximate said outer case, and a central opening, and disposing said plurality of LEDs around said central opening.
