Abstract
This application discusses components that can be used to prevent flame or hot gas transmission from the inside of a luminaire enclosure to the outside of a luminaire enclosure due to an internal explosion, thereby yielding an explosion encapsulating luminaire enclosure. Accordingly, the components and assemblies described herein can be safely integrated with systems that operate in the presence explosive gas.
Claims20
A flame protected luminaire enclosure comprising:
- a luminaire enclosure cover including a luminaire lens with a first lens surface;
- an LED protective lens array including a protective lens;
- a luminaire enclosure backing with a first backing surface and a second backing surface spaced apart from the first backing surface, wherein the first lens surface is configured to be coupled to the first backing surface;
- a pcb board including at least one LED element coupled to the second backing surface;
- and
- a luminaire cavity defined by a space extending between the first lens surface and the second backing surface;
- wherein an explosion encapsulating flame path is formed in a seam between the first lens surface and the first backing surface;
- and
- wherein the LED protective lens array is configured to be secured to the luminaire enclosure backing over the pcb board by an adhesive such that the LED protective lens forms a mechanical seal against the pcb board that disallows a flame from travelling into or out of the protective lens of the LED protective lens array.

An LED array comprising:
- an LED protective lens array including,
- a body having a first surface;
- and
- an LED protective lens extending from the body and including an LED accommodating cavity;
- an LED element fixed to a second surface, wherein the first surface of the body is configured to be attached to the second surface by way of an adhesive material applied to the first surface and/or the second surface;
- wherein the LED accommodating cavity is configured to overlay the LED element;
- and
- wherein attaching the LED protective lens array to the second surface via the adhesive forms a seal between the LED protective lens array and the second surface that disallows a flame from travelling into or out of the LED accommodating cavity when the LED protective lens array is attached to the second surface.
