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:
a housing defining a first side wall, a second, opposing side wall, and a first interconnecting wall connecting the first side wall and the second side wall, and further defining a first opening in the first side wall; an array of light-emitting elements positioned in the housing; a heat sink, wherein the array of light-emitting elements is electrically coupled to the heat sink, and wherein at least a portion of the heat sink is secured within the first opening of the first side wall of the housing; and a first deflector positioned to extend over at least a portion of the first opening such that the first deflector guides heat dissipated from the heat sink away from the housing in at least one direction.
