AIR DEFLECTORS FOR HEAT MANAGEMENT IN A LIGHTING MODULE

摘要

A lighting module has an array of light-emitting elements that is electrically coupled to a heat sink and a housing having a heat exit. The array of light-emitting elements is positioned in the housing and the heat sink is positioned to dissipate heat generated within the housing so that the heat is expelled through the heat exit. A deflector is secured to the housing and is positioned to extend over some portion of the heat exit. The deflector guides heat away from the housing in a direction. In some configurations, the deflector guides heat away from the housing in a direction that is opposite the direction in which the array of light-emitting elements emit light. Also, some lighting modules have multiple heat exits and may have multiple deflectors extending over a portion of the respective heat exits.

主权项

1. A lighting module, comprising:
an array of light-emitting elements; a heat sink, wherein at least a portion of the array of light-emitting elements is electrically coupled to the heat sink; a housing having a first heat exit, wherein the array of light-emitting elements is positioned in the housing, and wherein the heat sink is positioned to dissipate heat generated within the housing so that the heat is expelled through the first heat exit, the housing being a rectangular, box-shaped structure; and a first deflector secured to the housing and positioned to extend over at least a portion of the first heat exit, wherein the first deflector guides the heat away from the housing in at least one direction and is removable from the housing.
