1. A luminaire system comprising:
a luminaire enclosure comprising a luminaire enclosure cover having a first surface;
an explosion encapsulating luminaire enclosure lens disposed in the luminaire enclosure cover, the explosion encapsulating luminaire enclosure lens including a first lens surface and a second lens surface opposite to the first lens surface; and
a luminaire enclosure backing having a second surface and configured to be fastened to the enclosure cover and thereby form an explosion encapsulating seal in a seam formed between the luminaire enclosure backing and the luminaire enclosure cover, the luminaire enclosure backing includes a recessed portion that has a mounting surface for the pcb board;
wherein an explosion encapsulating flame path is defined in the seam;
wherein the first lens surface is sealing connected to the enclosure cover and the second surface faces the mounting surface and the pcb board;
wherein a luminaire cavity is formed between the luminaire enclosure backing and the second lens surface; and
wherein the second lens surface is flush with the second surface such that the depth of the recessed portion is substantially equal to the height of the luminaire cavity.
