Transparent Showcase Lighting Layout to Minimize Product Shadowing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional showcases often suffer from shadowing issues due to light sources, which can obscure products and hinder effective advertisement and visualization, especially when products are placed on lower shelves or in areas with complex geometries.
Innovation Solution
A showcase design featuring a transparent liquid crystal panel and an obliquely arranged light source unit between the front and upper frames, combined with a downhill bottom surface and oval rear face, minimizes shadowing by ensuring uniform light distribution and three-dimensional perception, while allowing for easy product arrangement and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source unit is installed in the showcase to illuminate products, then product visibility is improved, but shadowing occurs on products especially on lower shelves
Solution Approach 1:
The light source unit is arranged obliquely between the front frame and upper frame, changing the traditional vertical or horizontal lighting arrangement to a diagonal configuration. This spatial repositioning allows light to reach products on lower shelves from above and at an angle, illuminating products throughout the showcase volume while minimizing shadowing effects that would occur with conventional lighting positions.
Solution Approach 2:
The showcase employs a transparent display panel integrated with the front frame structure, combining display functionality with the showcase framework. This integration allows the light source to be positioned effectively while maintaining visual clarity and reducing structural interference with light paths.
2Loss of information
If a transparent display panel is installed on the front frame to display product information, then advertisement effects are improved, but the structure becomes more complex
Solution Approach 1:
The transparent display panel is merged with the front frame structure, integrating the information display function directly into the showcase framework. This combination eliminates the need for separate display mounting structures and allows the front frame to serve dual purposes: structural support and information presentation.
Solution Approach 2:
The front frame is designed with multi-functionality, serving both as the structural boundary of the showcase and as the mounting substrate for the transparent display panel. This universal design reduces the number of separate components needed and simplifies the overall structure while maintaining both structural integrity and display capability.
3Quantity of substance
If shelves are arranged horizontally to display multiple products, then product capacity is improved, but light cannot reach lower products due to blocking by upper shelves
Solution Approach 1:
The light source is positioned in the vertical dimension between the front and upper frames, illuminating products from above rather than from the side or front. This vertical lighting approach allows light to pass over upper shelves and reach products on lower shelves, solving the blocking problem while maintaining high product capacity through horizontal shelf arrangement.

Function Achieved in This Case
This configuration enhances product advertisement effects by reducing shadowing, providing improved visibility and stereoscopic viewing experiences, and allows for flexible product placement without edge shadowing, ensuring that all products are well-lit and prominently displayed.
Implementation Method 1
a light source unit configured to emit light into the showroom, the light source unit being obliquely arranged in a direction from the front frame to an upper frame among the frames
Implementation Method 2
a transparent liquid crystal panel is installed to a front face of a showcase to display an image related to a product

AI summary
A showcase including a plurality of frames including a front frame and an upper frame defining a showroom; a transparent display panel placed at the front frame among the frames, the transparent display panel displaying an image; and a light source unit configured to emit light into the showroom, wherein the light source unit is located between an opaque upper portion of the front frame surrounding the transparent display panel and the upper frame, and wherein the light source unit includes a plurality of lamps at each corner of the showcase and is obliquely arranged in a direction from the front frame to the upper frame, and positions of the plurality of lamps are increased in height with an increasing distance from the front frame to the upper frame.
