    Abstract: A light fixture including an electronic housing and at least one optical chamber positioned on each side of the electronic housing. In some embodiments, the optical chambers are positioned a distance from the electronic housing so as to avoid creation of a thermal path between the optical chambers and the electronic housing. Each optical chamber includes a heat sink and a plurality of LEDs mounted on a PCB that is, in turn, mounted on the heat sink. A reflector is positioned over at least a portion of the PCB. In some embodiments, vents extend through the heat sink and a fin extends upwardly from the heat sink and angles at least partially over at least some of the vents. In use, air enters the optical chambers and exits the fixture through the top vents in the heat sink. The air circulates over the reflector, carrying heat from the reflectors during the process. Heat is also conducted to the air from the heat sink. The angled fins extending over the top vents provide additional surface area for contact with the air and thus facilitate additional heat transfer from the heat sink.

    Abstract translation: 一种灯具，其包括电子壳体和位于电子壳体的每一侧上的至少一个光学室。 在一些实施例中，光学室与电子壳体定位一定距离，以避免在光学室和电子壳体之间产生热路径。 每个光学室包括安装在PCB上的散热器和安装在PCB上的多个LED，所述PCB又安装在散热器上。 反射器位于PCB的至少一部分上方。 在一些实施例中，通风口延伸穿过散热器，并且翅片从散热器向上延伸并且至少部分地至少部分地在至少一些通风口上。 在使用中，空气进入光学室并通过散热器中的顶部通风口离开固定装置。 空气在反射器周围循环，在过程中从反射器携带热量。 热量也从散热器进入空气。 在顶部通风口上延伸的成角度的散热片提供用于与空气接触的附加表面积，并且因此促进从散热器的附加热传递。
