Lighting fixture

摘要

The present disclosure relates to a lighting fixture that is configured to transfer heat that is generated by a light source and any associated electronics toward the front of the lighting fixture. The lighting fixture includes a heat spreading cup that is formed from a material that efficiently conducts heat and a light source that is coupled inside the heat spreading cup. The heat spreading cup has a bottom panel, a rim, and at least one sidewall extending between the bottom panel and the rim. The light source is coupled inside the heat spreading cup to the bottom panel and configured to emit light in a forward direction through an opening formed by the rim. Heat generated by the light source during operation is transferred radially outward along the bottom panel and in a forward direction along the at least one sidewall toward the rim of the heat spreading cup.

主权项

1. A lighting fixture comprising:
a heat spreading cup having a bottom panel integral with the heat spreading cup, a rim, and at least one sidewall extending between the bottom panel and the rim; a light source coupled to an interior surface of the bottom panel and inside the heat spreading cup, the light source being configured to emit light in a forward direction through an opening formed by the rim, wherein the light source is thermally coupled to the bottom panel such that heat generated by the light source during operation is transferred radially outward along the bottom panel and in the forward direction along the at least one sidewall toward the rim; a control module having electronics to control the light source and coupled to an exterior surface of the bottom panel opposite the interior surface; and a heat sink coupled to the exterior surface of the bottom panel opposite the light source, wherein the heat sink has an interior opening in which the control module is received once the heat sink is coupled to the exterior surface of the bottom panel.
