Description

Technical Field

[0001] This utility model relates to the field of emergency lighting equipment, specifically to an assembly structure for a marker light. Background Technology

[0002] Existing ultra-thin sign lights typically consist of a lamp housing (front cover and rear shell), a light guide plate, and a circuit board housing electronic components. The light guide plate has light-emitting points on its surface. Light emitted from LEDs on the circuit board is conducted through the light guide plate, converged and reflected by the light-emitting points, and finally shines through the sign holes on the lamp housing surface to form a visible mark. Because the light guide plate uses a point-emitting method, to improve the uniformity and visual effect of the sign graphic when viewed from the outside, a layer of diffusion paper is usually placed between the light guide plate and the sign holes to blur and disperse the light-emitting points, making the emitted light softer and more consistent.

[0003] Currently, there are two main assembly processes for ultra-thin marker lights: First, the diffuser paper is directly attached to the inner surface of the lamp housing, and then the light guide plate is glued onto the diffuser paper. However, the diffuser paper itself is extremely thin and has low mechanical strength, making it prone to tearing due to tension when the light guide plate is subjected to external force. Second, the diffuser paper is cut to a size matching the marker hole, allowing it and the light guide plate to be glued separately to the inner surface of the lamp housing. While this method avoids the diffuser paper being affected by the stress of the light guide plate, it significantly reduces the bonding area between the diffuser paper and the housing, making it prone to detachment. Furthermore, this structure requires additional cutting and processing of the diffuser paper, increasing process complexity and leading to reduced material utilization and resource waste.

[0004] In addition, both of the above assembly methods require two separate processes of pasting the diffusion paper and the light guide plate, resulting in a high rate of process repetition. This not only increases the difficulty of assembly but also significantly increases production costs. Utility Model Content

[0027] The marking hole 2 is an arrow-shaped hole 23, which has two acute angles, and the glue-passing hole 41 is disposed within the acute angles. This structure can prevent the acute angles from lifting up under force, thereby damaging the surface structure of the product and even endangering the personal safety of the user.
