Technical Field

[0001] The utility model relates to the technical field of building lighting, in particular to a sign lighting device for an exterior wall of a building. Background Art

[0002] Signage lighting devices on building exterior walls play an important role in modern buildings, especially at night or in low-light environments. Lighting signs can clearly indicate key information such as emergency exits, floor information, building names, etc., thereby improving the safety and recognition of buildings. Common application scenarios include public buildings such as shopping malls, office buildings, hospitals, and airports. These places have large traffic flows and high traffic demands. Clear and visible signage lighting devices are essential for guiding traffic and ensuring safety.

[0003] The existing sign lighting devices on the market usually require multiple lamp beads to be evenly distributed behind the lampshade plate to ensure that the sign plate can be fully and evenly illuminated. Although the distribution of multiple lamp beads can achieve uniform lighting, the light efficiency of each lamp bead is not fully utilized, and there is a large loss of light during transmission. This design leads to an increase in the number of lamp beads, which not only increases the initial installation cost, but also increases the frequency of maintenance and replacement of lamp beads. In addition, the configuration of multiple lamp beads consumes high power during use, which does not meet the requirements of modern energy conservation and environmental protection.

[0004] Therefore, there is an urgent need for a sign lighting device for a building exterior wall to solve the technical defects proposed in the above-mentioned technology. Utility Model Content
