Description

Technical Field

[0001] The utility model relates to the field of emergency lighting equipment, and particularly relates to an ultra-thin sign lamp. Background Art

[0002] Fire emergency lights are a guarantee for public safety emergencies and a mandatory measure for public fire protection. They have a wide range of applications and complex installation environments. Among them, fire emergency sign lights are usually installed at fire escape passages. When power outages, fires and other situations occur, they can realize the function of guiding emergency evacuation.

[0003] In fire emergency sign lights, the lamp body of the ultra-thin sign lamp has a simple design, and the light guide plate can conduct the light energy of the LED light source to the sign display areas such as direction arrows and running figures to a great extent in the whole lamp. The existing ultra-thin sign lamp is composed of a lamp housing formed by a front cover and a rear cover, a light guide plate and a circuit board. The surface of the lamp housing is provided with sign holes, and the circuit board and the light guide plate are arranged inside. The light of the sign holes is displayed outward through the sign holes. Due to the limitation of the material characteristics, the existing ultra-thin sign lamp can only use a lamp housing made of metal. However, the lamp housing made of metal needs to be stamped, and buckle holes also need to be stamped on the side. This requires extremely high quality of materials and fine craftsmanship, resulting in too high product cost and easy deformation after product assembly. The circuit board and the light guide plate are both fixed inside the lamp housing by gluing. In order to achieve good light effect and save energy, the layout of the LED light source needs to be manually operated and must be accurate. Otherwise, misalignment is likely to occur, leading to rework, which will reduce the yield rate of the product. Moreover, the assembly process of the circuit board during the installation of the circuit board is cumbersome, and the pasting operation also requires a lot of manual intervention for calibration, reducing the assembly efficiency.
