In this way, the connectivity of the entire marking hole is reduced, that is, the entire marking hole is divided into a plurality of independently formed small holes by the spacing between the connection points of certain strokes, and the spacing between the connection points of these strokes maintains the structural strength of the stamped part of the lamp housing in the whole or part to a certain extent. Further, due to the existence of the spacing / discontinuity, each adjacent stroke is not connected, which reduces the convex corners formed on the edge of the marking hole due to the connection of the strokes in the prior art, thereby avoiding the corners on the edge of the marking hole from being lifted up due to the stamping process. Therefore, the structure of the marking holes on the housings in some embodiments of the application, especially the spacing structure between the strokes of the characters in the marking holes, improves the manufacturability and safety of the lamp housing and the lamp.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0054] The inventor has found through research that in the prior art, due to the use of a default font, the various stroke parts of the marking hole 18 in the shape of a Chinese character 19 formed on the lamp housing 23 have more mutual connections and connections, that is, there are only a few intervals between the various strokes of the Chinese character 19, which results in a larger connected area in the marking hole 18 that constitutes the Chinese character 19 as a whole. Correspondingly, the stamped part of the lamp housing 23 targeted by the stamping process is a whole to a greater extent and has a larger area. Since more material is stamped out as a whole and completely at the stamped part of the lamp housing 23, the structural strength of the stamped part 41 on the lamp housing is relatively low during the entire stamping manufacturing process. As a result, the text part 19 of the marking hole 18, especially the corners β1 and β2 of some hollow characters, are easily lifted up due to stamping, which reduces the quality of (stamping) manufacturing and causes manufacturing defects, and is easy to scratch installers and users. Conversely, the lamp itself may also be damaged during use.

[0055] In addition, the inventors have found that among the strokes of Chinese characters, the strokes of characters in most commonly used fonts are not arranged in the horizontal or vertical direction, but in an inclined direction. Regardless of whether the strokes extend obliquely or vertically / horizontally, after the connection of two or three adjacent strokes in a single character, a larger connected "hollow area" will be formed, which reduces the structural strength of the stamped area 41. Moreover, the "hollow area" is partially "bent" in shape, for example Figure 1c The part where the strokes H1 and H4' are connected. When the strokes H1 and H4' are subjected to the stamping process, while the shell material at the positions where the strokes H1 and H4' are located is removed, the solid material retained around the strokes H1 and H4' after stamping will form sharp angle structures β1 and β2 corresponding to the above-mentioned "bend" shape at the place where the two strokes H1 and H4' are connected. These (sharp) sharp angles β1 and β2 are composed of solid material on the shell, and the angle thereof is less than 180°. Even in the case where the strokes H1 and H4' are connected / intersected at an angle, the angle of the solid sharp angle β2 formed is less than 90°. Moreover, since the shell material of the sharp angle structures β1 and β2 is already less, such as Figure 1a , Figure 1bAs shown, the overall structural strength is weak, especially at the tips of the sharp corners β1 and β2, where the anti-bending ability is poor. Therefore, during the process of stamping the logo holes in the shape of characters, this "sharp corner" structure is more likely to be lifted up (not shown in the figure) along with the stamping action of the stamping equipment, resulting in manufacturing defects. In some cases, the housing material may even directly break at the lifted corner, thereby damaging the logo pattern that the logo hole 18 should form.

[0056] Conversely, as Figure 1b shown, if two adjacent strokes are not connected and there is a certain gap A1 between them. When stamping a single stroke on the lamp housing, generally only an angle α1 greater than 180° can be formed on the housing. This angle α1 is composed of physical material and is not a hollow structure. Since this angle is greater than 180°, the housing material at the angle α1 does not have a sharp corner structure. Therefore, the corresponding physical material angle α1 will not be driven by the stamping head of the stamping equipment to form a defective structure with a lifted corner during the stamping process. Moreover, after stamping and forming such characters with more gaps between each stroke, more physical material remains on the housing, and the distribution is more continuous. Therefore, the structural strength of the part 41 (during and after the stamping process) of the housing 23 that is stamped is also improved.

[0057] In summary, if the strokes within a certain character are more spaced apart and these strokes are connected as little as possible. Through this layout structure of the strokes, the number of (local) bending shapes in the hollow area of the logo hole 18 on the housing can be reduced. Correspondingly, the sharp corner structures β1 and β2 on the physical edges of the logo hole 18 are also reduced.

[0058] Based on these findings, the inventors believe that it is not appropriate to directly apply some default and commonly used fonts to the hollow Chinese characters on these lamp housings, because in the default / common fonts, there are more connections between the strokes of the characters, which are likely to cause manufacturing defects such as the lifted corners mentioned above, reducing the manufacturability, assembly safety, and use safety of the product.

[0059] At the same time, the inventors put forward an idea: in the layout structure of the strokes of the hollow characters forming the logo holes, especially Chinese characters, more discontinuities and intervals are designed between the strokes so that these strokes are not continuous.

[0060] The following further illustrates the present application by way of embodiments, but the present application is not limited to the scope of the embodiments accordingly.

[0061] Those skilled in the art should understand that although the following is combined with Figure 1a 、 1b1c, taking fire emergency sign lamps as an example, some embodiments of the application of the sign lamps or lamp housings are schematically introduced, but the technical solutions and related hollow structure designs therein can also be applied to other types of sign lamps or lamp housings other than fire emergency sign lamps. The scope of protection of this application is defined by the attached claims.

[0062] Figure 1a The structure diagram of an emergency sign lamp housing of the utility model is shown. Figure 1b Then Figure 1a FIG. 1 is a partial enlarged schematic diagram of the Chinese characters 19 on the lamp housing 23 in FIG.

[0063] like Figure 1a , Figure 1b As shown, an emergency sign lamp housing disclosed in this embodiment includes a housing 23, and a sign hole 18, 18' is provided, and the sign hole 18 has a shape of at least one character 19;

[0064] Among them, compared with Figure 1c The corresponding font shape of the character "安" is, a) at least one character 19 has a larger spacing between strokes of a single character (such as "安"), and / or, b) at least one character 19 has a more spacing A1 between strokes of a single character (such as "安") .

[0065] Optionally, in some embodiments of the lamp housing, a spacing A2 may be provided between the left-falling stroke H2 and the right-falling stroke H3 in the character “女”. Figure 1b The interval A2 shown in FIG. 1 can be set larger than Figure 1c The interval A2' shown in is larger, for example, the interval W3 between the stroke H2 and the horizontal stroke H3 in "女" is larger than the width of the horizontal stroke H3 in "女" (not marked in the figure). Of course, the interval W3 usually refers to the minimum value among all possible distances between the stroke H2 and the horizontal stroke H3. This interval W3 is full of shell materials that have not been punched out, so the larger the interval W3, the better the mechanical stability of this section of the laterally extended solid material 11, and it is not easy to tilt up. In addition, during the assembly process of the fire emergency sign lamp, it may be necessary to apply glue at the interval A2 to fix the shell material of this part that is basically in a dangled state, or it may be necessary to apply glue on the inner side of the face cover including the interval A2 to mount the optical diffusion paper on the inner side of the face cover at the sign hole, and the interval A2 has a larger width, which is conducive to improving the coating efficiency of glue in such assembly processes and improving the assemblability of the lamp.

[0066] On the other hand, in the face cover of a fire emergency sign lamp in the prior art shown in Tu 3, in the "safe exit" sign pattern, in the "female" located at the lower part of the character "安", the distance between the horizontal stroke H2' and the horizontal stroke H3' is relatively small. Therefore, the area 88 is formed to be large in size, and the connecting portion A2' is elongated. This "big head and thin neck" structure has low mechanical stability and is easy to warp due to stamping. In addition, it is difficult to apply glue on the elongated connecting portion A2', which reduces the assemblability of the lamp.

[0067] Optionally, in some embodiments, the marking hole 18 or the plurality of characters 19 are hollow structures;

[0068] At least one character 19 is an English character and / or a Chinese character;

[0069] One or more of the Chinese characters 19 have an up-down structure or a left-right structure; for example, “安” has an up-down structure.

[0070] The intervals A1, Q2', Q2 are located between the upper and lower parts of the upper and lower structures, for example, between the Baogai head of the Chinese character "安" and the "女" part, or between the Ren head of the Chinese character "全" and the "王". Of course, the "人" and "王" here can be regarded as two independent Chinese characters, or as the upper and lower parts of the Chinese character "全". For the former, "人" and "王" are arranged in one column, while the intervals Q2', Q2 are located between the two Chinese characters "人" and "王".

[0071] Alternatively, the Chinese character may also include “人”, and the interval Q1 may also be located between the left and right parts of the left-right structure, such as between the left and right strokes of the Chinese character “人”.

[0072] Optionally, in some embodiments, the Chinese character 19 may be one or more of: safety, security, security, safety exit, person, etc.;

[0073] Optionally, the interval A1 is located between the roof H1 of the character “安” in the safety exit a) and the character “女” under the roof. Of course, the intervals Q2', Q2 can also be set between the herringbone of the character “全” in the “安全考试” and the character “王” under the herringbone.

[0074] In the above embodiment, if Figure 1bAs shown, the Baogai head H1 and the "女" under the Baogai head are separated by the shell material A1. The two holes corresponding to the Baogai head H1 and the "女" do not form a connected whole, but are separated by the shell material A1 into two relatively small holes, namely, hole H1 and holes H3, H4, and H2. During the stamping process, the shell has a stronger mechanical structure, which can better withstand the external force of stamping, and it is also more likely to keep the shell material without warping corners and edges after being stamped. Moreover, since there is a shell material A1 on the shell 23 that continuously crosses between a) the Baogai head H1 and b) the "女" under the Baogai head, the hollow area in the character "安" is separated into two upper and lower parts. Therefore, from the overall point of view, the integrity and coherence / continuity of the shell material in the area 41 where the "安" character is located are improved, so that the structure of the area 41 is more stable and less prone to deformation during the stamping manufacturing process or subsequent use.

[0075] In some preferred embodiments, the interval Q1, and Figure 1b The left and right intervals Q2' and Q2 shown are distributed in the character "全" at the same time. Figure 1b As shown, after the area 41 is stamped, the area Q12 located between the herringbone and the character "王" in the character "全" is connected to the other parts of the shell through the solid materials on the three intervals Q1, Q2', and Q2. The structure has strong stability, and the area Q12 is not easy to warp up during the stamping process or subsequent assembly and use.

[0076] On the contrary Figure 2 In the prior art, only the left and right strokes of the herringbone in the character "全" are solid materials, so the area enclosed by the herringbone and "王" (the enclosed area corresponds to the area Q12 in the present application, but Figure 2 The outer shell 23 is connected to the outer shell 23 only by the solid material between the left and right strokes. This "big head and thin neck" structure is very unstable, which causes the enclosed area between the herringbone and the "王" to easily warp up during the stamping manufacturing process or the subsequent assembly and use.

[0077] In some embodiments of the present application, the marking holes H1, H2, H3, H4 opened on the housing of the lamp have the shape of characters such as "安" or "全", and compared with Figure 2Compared with the font shapes of the characters such as "安" and "全" used in the prior art shown in the figure, the strokes within a single character of the lamp housing of the embodiment of the present application have more intervals A1 and A2. Specifically, by shortening the length of these strokes, it is possible to prevent the strokes from forming an intersecting and connected structure. In this way, these intervals A1 and A2 are generally composed of the solid material of the shell. After the shell is subjected to the stamping process, these solid materials are still maintained between the corresponding two strokes. In this way, the connectivity of the entire marking hole is reduced, that is, the entire marking hole, such as the character "安", is divided into two parts: small hole H1, small hole H3, H2, and H4 through the intervals A1 and A2 at the connection between certain strokes. The intervals A1 and A2 at the connection between these strokes maintain the lamp housing 23 to a certain extent. Figure 1b The global or local structural strength of the shell material of the stamped portion 41 selected by the dashed line is shown, and the relatively sharp angles, or sharp angles β1 and β2, formed by the direct connection of the strokes are reduced. The sharp angles formed by this solid material are in a small-sized protruding shape, and their structural strength is also low, and they are easy to warp up during stamping. Therefore, Figure 1b As shown, the structure of the marking holes 18, 18' on these shells 23 in some embodiments of the application, especially the spacing structures Q1, Q2', Q2, A1, A2 between the strokes H1, H3, H2, H4 of the Chinese characters 19 in the marking holes, make the edges of the marking holes 18, 18' have higher structural strength, especially at sharp corners, and are not easy to warp due to the stamping manufacturing process.

[0078] If you follow Figure 1b In the Chinese character for "安", the strokes of the character "女" are extended upwards, as shown by the dotted line in the figure, and connected to the Baogaitou, and the edge of the logo hole will be added as follows: Figure 1c The two protruding sharp angles shown in the figure, wherein angle β1 is less than 180°; and angle β2 is less than 90°, forming a sharper angle. The hollow mark hole structure of "intervals between strokes" in some of the above embodiments is applied to the character "全", while the "intervals between strokes" structure is not applied to the character "安". As a suboptimal embodiment of the present application, the character "安" can be used in conjunction with Figure 1b The hollow logo hole in the figure is described for comparison.

[0079] Of course, the protruding part above the "女" under the character "安" will form two left and right angles α1 even if it does not extend upward to connect with the top of the character "安". Figure 1bAs shown, the angle α1 formed by the solid material on the shell 23 itself is an angle greater than 180 degrees. Here, the shell material forms a "semi-enclosed" structure or a concave structure relative to the local hollow hole. From another aspect, as shown in the figure, the shell material here does not form a sharp-angled convex part, so the structural strength of the shell here is relatively large, and no warping structure will be formed due to stamping. Therefore, on the whole, if the "女" part of the character "安" is extended upward and connected to the "宝盖头" in the character "安", two sharp corners will be added, and then, after the shell is stamped, two warped sharp corners will be formed.

[0080] Of course, while avoiding the formation of the above-mentioned sharp-angle structure, to a certain extent, the more such intervals there are and the wider the intervals are, the more obvious similar technical effects may be.

[0081] It should be noted that for the hollow structure of the logo hole, a physical through hole is formed at the logo hole of the shell through stamping and other processes during the manufacturing process. However, this does not mean that the place must be hollow when the lamp is manufactured or in use. It can also be filled with light-transmitting parts and other components to (basically) close the logo hole and only keep it optically transparent to form an optical through hole.
