And lid 212 leans forward behind the first half for the first half lamps and lanterns inner space diminishes, and light gathers more in the space, and light is covered through the back lid that inclines to the face lid reflection more easily to the sign face, has promoted light intensity, has compensated to a certain extent the first half casing because of keeping away from the light source board the light weakening that produces.

Further, optionally, the flag hole is an optical through hole, which means that the flag hole optically penetrates the face cover, and is not limited to a physical penetrating structure. The optical openings may also be formed in the corresponding locations of the cover, for example, using some transparent material, but in this case the indicia openings in the cover do not physically extend through but rather retain a transparent, light-transmitting characteristic. In popular terms: the logo apertures remain light transmissive but are not necessarily "breathable". Accordingly, the optical surface of the marker is "exposed to the outside" through the marker hole of the face cover, also referred to as "optical exposure", without being limited to being physically through exposed. For example, a light-transmitting paper or a light-transmitting member may be further disposed in the mark hole, and the mark member is optically exposed to the outside through the light-transmitting paper or the light-transmitting member.

In terms of "inside the periphery of the cover", "inner wall of the periphery of the cover", "inside the opening rim", "inside the periphery of the lamp body", etc., the inner wall/inside, if not explicitly identified in some embodiments and the associated drawings, means: the surface facing the interior of the lamp body/luminaire, or in the direction of the interior of the luminaire, after the luminaire has been assembled. While the surface facing the exterior of the lamp body/fixture is the outer side/wall. In other embodiments, the terms "inside", "outside", "inner surface", "outer surface" and the like of the "opening part"/"edge"/"end part"/"rear cover"/"frame" have the same or similar meanings, and thus, the description thereof is omitted.
