LED Strip Light With Dual-Surface Reflector for Shelf Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED strip lights for shelf signboards fail to provide uniform and effective illumination, particularly for items on lower shelves, leading to reduced customer experience and increased energy costs due to the need for additional lighting sources.
Innovation Solution
An LED strip light design featuring a strip-shaped lamp chamber with a reflective device comprising first and second reflective surfaces and a boundary line, positioned to direct light towards both the upper and lower transparent edges, enhancing illumination of articles on both the display side and below the laminate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED strip light is installed only from the top of the laminate, then the structure is simple and energy consumption is low, but the display side of articles cannot be highlighted and illumination is uneven
Solution Approach 1:
The lamp chamber is segmented into multiple functional surfaces: a first light-emitting surface for top illumination, a second light-emitting surface for side illumination, and a reflective surface for light redirection. This segmentation allows different portions of the laminate to be illuminated effectively without requiring multiple separate lighting fixtures.
Solution Approach 2:
Different surfaces of the lamp chamber are designed with different optical properties: transparent or translucent surfaces for light emission, and reflective surfaces for light redirection. This local differentiation of optical qualities enables the single lamp chamber to perform multiple illumination functions simultaneously.
2Illumination intensity
If additional lamps are installed on the side of the laminate near the column, then illumination of the dark side is improved, but costs increase and energy is wasted
Solution Approach 1:
The lamp chamber is designed as a multi-functional component that simultaneously provides top illumination through the first light-emitting surface and side illumination through the second light-emitting surface and reflective surface. This universal design eliminates the need for separate side-mounted lamps, reducing both cost and energy consumption.
Solution Approach 2:
Multiple illumination functions (top lighting and side lighting) are merged into a single lamp chamber structure. The reflective surface redirects light to illuminate the side of the laminate that would otherwise require a separate lighting fixture, combining the functions of multiple lamps into one energy-efficient unit.
3Ease of operation
If traditional lighting is used, then the light source is simple, but the display side of articles is not highlighted and customer experience is reduced
Solution Approach 1:
The lamp chamber employs asymmetric light distribution through its differently oriented light-emitting surfaces and reflective surfaces. This asymmetric design directs light preferentially toward the display side of articles on the laminate, highlighting them for customers while maintaining overall illumination balance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides accent illumination for the first row of articles facing customers and illuminates the space below the laminate, improving the shopping experience while reducing energy consumption by optimizing light distribution.

AI summary
An LED strip light for shelf signboards, comprises a strip-shaped lamp chamber, and an LED light-emitting module. The strip-shaped lamp chamber comprises a card board connecting edge, a non-transparent edge, an upper transparent edge and a lower transparent edge. The upper transparent edge is parallel to the laminate. The LED light-emitting module comprises at least one LED chip, and a strip-shaped reflective device. The strip-shaped reflective device comprises a first reflective surface and a second reflective surface. The first reflective surface reflects all the incident lights thereon toward the upper light transparent edge. The second reflective surface reflects all the incident lights thereon toward the lower transparent edge. Due to the structure of the strip light chamber and the LED light-emitting module, the LED strip light for shelf signboards allows the first row of the article display side facing the customers which are placed on the laminate and the space below the laminate to be illuminated so as to improve the user's shopping experience.
