Abstract
A metal halide gas discharge lamp ( ) luminaire ( ) includes an acrylic lens ( ). The metal halide lamp ( ) is subject to non-passive failure whereby not particles of quartz or ceramic arc tube ( ) material and tungsten electrode ( ) material fall as hot (e.g. 1100 ° C.) debris. The interior, upper surface ( ) of the lens ( ) is ignition-resistant and, in exemplary embodiments, comprises a thin coating ( ). In the event of non-passive failure of the lamp ( ), hot debris particles fall on to the acrylic lens ( ). Not only is there no flame, but hot debris particles do not sink into the material of the acrylic lens. Thus, containment is maintained.
