Abstract
A light fixture that utilize multiple sheets of MCPCB for reduced costs, weight, and thermal, mechanical, and/or optical controls. In other embodiments, a heat sink may be formed by extruding a block of material to form a heat sink that utilizes a venturi and chimney effect, which may include attached MCPCB. Specific embodiments may utilize a plurality of MCPCB sheets or other pliable materials, which may be mirrored over a central axis or an extruded heat sink to create an open upper surface with a chimney effect
Claims8
An embedded heat sink within a light fixture comprising:
- a first sheet formed of metal core board, the first sheet having a first bend in a first direction and a second bend in a second direction, the first direction and the second direction being opposite directions, the first sheet including a first vertical sidewall extending from the second bend;
- a light source configured to generate heated air, wherein the light source is positioned between the first bend and the second bend;
- a second sheet coupled to the first sheet, the second sheet that mirrors the first sheet over a central axis of the light fixture, the second sheet including a second vertical sidewall;
- a vertical stack positioned between the first sheet and the second sheet formed of the first vertical sidewall and the second vertical sidewall, the vertical stack being aligned with the central axis of the light fixture and having an exposed lower surface and an exposed upper surface, wherein the heated air generated from the light source flows from the exposed lower surface to the exposed upper surface of the vertical stack.
