Mark and Sign Illuminating Device with Ring-Shaped LED
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic signs and marks struggle to be clearly visible and readable, especially in urban areas with high traffic flow and interference from street lamps and neon lights, due to limited observation angles and light reflection properties, which hinder driver and pedestrian visibility.
Innovation Solution
A mark and sign illuminating device featuring an LED light source in an annular transparent layer with a wide incident angle range (1-179 degrees) and a light reflecting layer, combined with a geometric prism or arc-shaped reflecting sheet, enhances visibility by providing comprehensive reflection and observation angles, and includes a CPU module for intelligent control and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If independent illuminating light sources are mounted at an extension part on a post for fixing the guideboard, then the guideboard can be illuminated at an angle in a near distance, but the light source incident angle collides with front lamp light sources causing limited observation angle and reduced visibility at shorter distances
Solution Approach 1:
The patent transitions from single-angle independent illumination to multi-angle ring-shaped illumination. The ring-shaped LED illuminating light source provides light from multiple dimensions and angles simultaneously, allowing the guideboard to be visible from various observation angles while avoiding collision with front lamp light sources.
Solution Approach 2:
The patent employs adjustable incident angles for the ring-shaped illuminating light source, enabling dynamic adaptation to different traffic conditions and observation requirements. The system can adjust illumination angles to optimize visibility at different distances and conditions.
2Area of stationary object
If light reflecting marks and signs are mounted at a high position above the roads, then they can cover broader areas, but they do not have a wide observation angle and drivers cannot have a clear understanding when identifying and reading marks and signs
Solution Approach 1:
The patent adds multi-angle illumination capability to high-mounted guideboards by using ring-shaped LED light sources. This provides wide observation angles while maintaining the high mounting position for broad coverage, allowing drivers to clearly read signs from various angles and distances.
Solution Approach 2:
The ring-shaped illuminating system serves multiple functions simultaneously: it provides illumination from multiple angles, enhances visibility at both long and short distances, and works effectively in various lighting conditions including urban environments with street lamps and neon lights.
3Illumination intensity
If conventional light reflecting signs are used in urban areas with street lamps and neon lights, then they can provide basic visibility, but the interference from other light sources severely interferes with the abilities of the drivers to see and read the marks and signs
Solution Approach 1:
The patent changes the illumination parameters by using ring-shaped LED light sources with adjustable incident angles, providing controlled and directed illumination that cuts through urban light interference. The system optimizes light distribution to enhance sign visibility despite the presence of street lamps and neon lights.

AI summary
A mark and sign illuminating device and system. The device is a device in which a transparent light guide layer (1203), a light reflecting layer (1204) and border rims (1251, 1252) are formed integrally. An LED illuminating light source LED1 and an LED illuminating light source LED2 are provided in the transparent light guide layer (1203). The reflective layer (1204) is provided with overlapping incidence of effective incident angles within the range of 360 degrees in the transverse direction and within the range of about 1 degree to about 179 degrees in the longitudinal direction, so that wide effective reflection angles and observation angles are formed. The advantage is that marks, signs and warning marks can be identified, seen and read more easily.
