Small Internally Illuminated Sign

The Small Internally Illuminated Sign is a high-visibility traffic signage solution designed with an integrated aluminum alloy frame and built-in edge-lit structure. It incorporates a light guide plate system to achieve uniform illumination across the entire sign surface.

Compared with conventional reflective signage, this internally illuminated design provides active light emission, ensuring clear visibility in both daytime and nighttime environments. Under adverse weather conditions such as rain, fog, or low-light scenarios, visibility performance can be significantly improved—up to several times higher than standard passive reflective signs.

The product is widely applied in urban roads, expressways, and highway traffic systems, supporting both safety management and visual guidance while maintaining low energy consumption and modern urban aesthetics.

Key Functional Features

Uniform Illumination with High Visibility

The sign adopts full-surface light guide technology combined with LED optical design to ensure even brightness distribution. This reduces glare and eliminates dark zones, providing consistent visual clarity under all lighting conditions.

Slim and Durable Structural Design

The frame is made of a one-piece aluminum alloy structure, offering strong mechanical stability and long service life. With an ultra-thin profile of ≤12mm, the design maintains a clean and modern appearance suitable for urban infrastructure applications.

Dual Power Compatibility

The system supports both solar power and AC mains power supply, allowing flexible installation in different environments. It also supports multiple operating modes, including continuous lighting and programmable flashing patterns.

Intelligent Warning Integration

The sign can be integrated with radar detection systems to enable real-time traffic warnings. This enhances active safety functions by providing dynamic alerts based on approaching vehicles or pedestrians.
