    • A luminaire has a deck assembly pivotally mounted on a housing by a separable connection to allow removal of the deck assembly from the luminaire. A refractor assembly is pivotally connected to the deck assembly, also by a separable connection for movement with or independent of the deck assembly. A selectively operable latch has a latched position holding the housing, deck assembly, and the refractor assembly, as a unit, an intermediate position holding the deck and refractor assemblies together but releasing them for movement relative to the housing, and an open position wherein the refractor assembly is released for movement relative to the deck assembly. A releasable connection separate from the latch is also provided between the housing and deck assembly. Selective access to all interior elements of the luminaire is thus provided.
    • 灯具具有通过可分离连接枢转地安装在壳体上的甲板组件,以允许从灯具移除甲板组件。 折射器组件也通过可拆卸连接枢转地连接到甲板组件,以与甲板组件一起移动或独立于甲板组件。 可选择性地操作的闩锁具有锁定位置,其保持壳体,甲板组件和折射器组件作为一个单元,中间位置将甲板和折射器组件保持在一起,但是释放它们以相对于壳体移动,以及打开位置,其中 折射器组件被释放以相对于甲板组件移动。 在壳体和甲板组件之间还设有与闩锁分开的可释放连接。 因此提供了对照明设备的所有内部元件的选择性访问。
