Thereby, after the first cover Line391 is detached from the first opening part 2-13-1 ', the light source board 17-7 can be exposed to the outside through the first opening part 2-13-1 ', while the first cover Line391 has a smaller dimension/size, and on the first cover Line391 having a small size, only a small number of connecting parts (e.g., snaps) for connecting with the first opening part 2-13-1 ' need to be provided, and these simplified structures all reduce the damage rate when detaching the first cover Line 391. Further, in the above/below-described embodiments or combinations thereof, the position of the first cover plate Line391 detachable from the opening portion 2-13-1' or the lower edge thereof within the housing 1-10 corresponds to the mounting position of the light source board 17-7, and the maintenance work for the inside is concentrated on the light source board in many cases. Since only mechanical parts which are not easily damaged are substantially disposed in the space inside the first cover Line391, the first cover Line391 does not generally need to be detached. If the sign face covers 4-10 are often pried apart in their entirety, the face covers, especially the portions with the sign pattern/sign holes, are easily damaged, increasing maintenance effort and failure rate, especially in the case of face covers or their snaps made of plastic, frequent removal may result in damage to the snaps. In some embodiments, the first cover Line391 is separately detachable for maintenance or the like, because the size is small, the number of the fasteners required on the first cover Line391 is small, and the fasteners are not easily damaged during the detachment process, and in addition, the independent detachment of the first cover Line391 is more convenient than the detachment together with the logo cover 4-10. The lamp/lamp housing is more convenient to maintain and install, and the assembling performance and the maintainability of the lamp housing/lamp are improved.

Alternatively, in some embodiments, the light source board 17-7 is disposed along the lower side wall 12-14 of the housing 1-10, and the covers 4-10, 10-11 are disposed side by side above and below the first cover Line391, as shown in fig. 1A, 2A, 1B, and 2B, the lower edge of the cover forms a Step position Step23, a) the upper edge of the first cover Line391 presses and fixes the Step position Step23, or B) the lower edge of the cover is fastened to the upper edge of the first cover Line391 through the Step position Step 23.

The Step23 is fastened to make the connection between the two parts stronger, and the Step23 makes the connection between the two parts horizontal or smooth, which improves the strength of the structure and the appearance, especially when the first cover Line391 is connected to the sign cover 4-10 side by side and closes the opening 2-13-1' of the front side of the housing 1-10 for displaying the sign pattern to the outside.

Optionally, in different embodiments, the cover may be implemented in different forms, such as: a first sign face cover 4-10 or a rear cover 10-11, wherein a) a sign Logo mark Logo10 is transversely arranged on the first sign face cover 4-10 (as shown by an arrow trans23 in the figure), or b) a sign hole having a shape of the sign Logo mark Logo10 is transversely arranged on the first sign face cover 4-10.

The first label cover 4-10 'further comprises a snap-in edge SnaP S18, which in the embodiment shown is embodied as a rib/edge-like structure of substantially square cross-section raised along the periphery of the label cover, the rib profile substantially conforming/matching the shape of the inner edge of the mouth 2-13-1', the snap-in edge being wholly closed and/or continuous but not interfering with its local breaking, which contributes to improved sealing. The plurality of second Snap-in pieces Snap18 are integrally formed outside the Snap edge Snap S18. The body of the first logo cover 4-10 'may, in some embodiments, be understood to be the main body portion on which the logo design/symbol is disposed, or other portions of the first logo cover 4-10' other than the snap edge snap s18 or the snap fastener. Wherein, the above-mentioned snap edge snap s18, a) the above-mentioned snap edge snap s18 extends from the periphery of the first sign face cover 4-10 'body into the first opening 2-13-1', or b) the above-mentioned snap edge snap s18 extends from the periphery of the first sign face cover 4-10 'body into the inner side of the body substantially perpendicular to the first sign face cover 4-10' body (i.e. extends to the depth direction/longitudinal direction of the housing 1-10), here, in the use state of the emergency marker light lamp, the outer side of the sign face cover 4-10 'body is a part of the outer surface of the lamp and is visible for the end user, and the inner side of the sign face cover 4-10' body is the other side opposite to the outer side.

Moreover, a plurality of fasteners are integrated on one fastening edge SnaP S18, and the damage probability of each second fastener SnaP18 is also reduced. In addition, due to the existence of the buckling edge SnaPS18, the sealing performance of the mark surface cover on the opening part is better, and the sealing performance of factors such as light, dust and the like is enhanced.

Optionally, in some embodiments, a) the first plurality of snaps Snap23 are male snaps and the second plurality of snaps Snap18 are female snaps. In other embodiments, B) the first fasteners Snap23 are female fasteners, and the second fasteners Snap18 are male fasteners. In still other embodiments, the first fasteners Snap23 and the second fasteners Snap18 are both male fasteners, especially when the housing 1-10 and/or the first sign cover 4-10 ' are made of plastic, for example, because of the elasticity and shape of the plastic can be changed by external force, even if the corresponding fasteners on the inner edge of the opening 2-13-1 ' and the outer side of the Snap edges Snap s18 are both male fasteners (not limited to the combination of through holes and fasteners), the sign cover can be better fastened to the first opening 2-13-1 ' by Snap fit.

Wherein the second sidewall, the first sidewall, the third sidewall, and the fourth sidewall are, in other embodiments or also referred to as: the lower side wall, the upper side wall, the left side wall and the right side wall, and the description is omitted.

The lower edges of the second cover plates 4-10 form step positions, A) the upper edge of the first cover plate Line391 presses the step positions, or B) the lower edges of the second cover plates 4-10 are clamped on the upper edge of the first cover plate Line391 through the step positions, wherein the lengths of the upper edges and the lower edges of the second cover plates 4-10 and the first cover plate Line391 are both larger than the lengths of the left edge and the right edge.

The step positions enable the joint of the two parts to be more firmly connected, and the joint of the two parts can be in a horizontal or smooth state due to the step positions, so that the structural strength and the aesthetic appearance are improved, and the step positions are more significant particularly when the first cover plate and the second cover plate are connected side by side and close the first opening part 2-13-1' on the front side of the shell 1-10 for displaying the mark patterns outwards. In addition, the second cover plate in some embodiments may be referred to as a label cover in other embodiments.

The lower edge of the first cover plate Line391 extends into the first opening 2-13-2' substantially vertically to form a Snap edge Snap s18, and the plurality of second Snap fasteners Snap18 are integrally formed at the outer side of the Snap edge Snap s18 or the Snap edge Snap s 18.

The buckling edge SnaP S18 is arranged, so that a plurality of buckling pieces distributed on the periphery of the mark surface cover 4-10 are integrated integrally or are connected in a conjoint manner, the mark surface cover 4-10 is favorably positioned and installed integrally in the first opening part 2-13-1', and the position of a plurality of discrete second buckling pieces SnaP18 does not need to be correspondingly adjusted to be in butt joint with the first buckling pieces SnaP23 in the opening part. Moreover, a plurality of fasteners are integrated on one fastening edge SnaP S18, and the damage probability of each second fastener SnaP18 is also reduced. In addition, due to the existence of the snap edge SnaPS18, the mark surface cover 4-10 has better sealing performance on the opening part 2-13-1 'and the opening part 2-13-2', and the sealing performance on the aspects of light, dust and the like is further enhanced.

Optionally, in some embodiments, a) the first plurality of snaps Snap23 are male snaps and the second plurality of snaps Snap18 are female snaps; or, B) the plurality of first Snap fasteners Snap23 are female fasteners and the plurality of second Snap fasteners are male fasteners; or, C) the plurality of first Snap-fit members Snap23 and the plurality of second Snap-fit members Snap18 are both male snaps; the housing 1-10 and/or the first logo face cover 4-10 have elasticity.

Of course, the two ends of the support plate 15-10 are not limited to being directly connected to the upper side wall 11-10 and/or the lower side wall. The support plates 15-10 may also have ends adjacent to/near the upper and lower sidewalls 11-10, respectively. As shown in fig. 10c, unlike the case and the rear cover structure of the case of the embodiment in fig. 10a, there are: the first portion of the support plate 15-10 is adjacent to the upper sidewall 11-10, and the second portion of the support plate 15-10 is far away from the upper sidewall 11-10 and connected/close to the left sidewall 13-10, which is not described again for brevity.

Further, as shown in FIG. 10c, the left side wall 13-10 and the right side wall 14-10 are disposed opposite to each other and are adjacent to the upper side wall 11-10 and the lower side wall 12-10, respectively, thereby forming a rectangular opening portion, and the side walls to which the upper side wall 11-10 is adjacent include the left side wall 13-10 and the right side wall 14-10.
