As shown in fig. 1a to 1d, this embodiment discloses a fire emergency sign lamp housing, including:

a flag 1800;

the first cover body 110 and the second cover body 160 are buckled with each other;

the first cover member 110 and/or the second cover member 160 are formed with a mark hole 180, and the mark member 1800 is received in the mark hole 180, as shown in fig. 1 b.

Optionally, in the fire emergency sign lamp housing in some embodiments, the sign hole 180 further includes a first sub-sign hole and a second sub-sign hole, which are respectively opened in the first cover 110 and the second cover 160, and the two sub-sign holes are substantially centrosymmetric, which is more common in the double-sided sign lamp such as fig. 4a and 4 b. The mark piece also comprises a first sub mark piece and a second sub mark piece which are respectively clamped and fixed in the first sub mark hole and the second sub mark hole;

the support post 320 bumps are formed in: inside the first sub-flag, and/or inside the second sub-flag, as shown.

The supporting column 320 on the first sub-marker and the supporting column 320 on the second sub-marker are relatively raised and abut against each other; alternatively, the support post 320 on the first sub-flag abuts the inside of the second sub-flag. The symmetrical structure can avoid twice die sinking manufacture of the two sub-markers, and improves the manufacturability and the manufacturing efficiency.

Optionally, in the fire emergency sign lamp housing/luminaire in some embodiments, the first cover 110 is made of metal or plastic;

the second cover body is made of metal or plastic;

the first cover 110 is a front cover 208, and the second cover 160 is a rear cover 210; alternatively, the second cover 160 is a front cover 208, and the first cover 110 is a rear cover 210; or, the first cover body 110 and the second cover body 160 are both the surface cover 208; the mark hole 180 is arranged on the surface cover 208;
