Shelf Lighting Mechanism With Segmented Lens Irradiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shelf lighting systems require multiple lamps to illuminate both upper and lower regions of shelves, leading to increased complexity and cost.
Innovation Solution
A shelf lighting mechanism featuring a lamp with a concave lens having distinct irradiation parts to direct light towards both upper and lower areas, allowing simultaneous illumination with a single lamp, and a connecting arm assembly for installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If two sets of lamps are used to illuminate upper and lower regions respectively, then illumination coverage is improved, but device complexity and cost increase
Solution Approach 1:
The lens is divided into distinct irradiation parts (first and second irradiation parts) with different beam angles, where each part is responsible for illuminating a specific region (upper or lower). This segmentation allows a single lamp to achieve the illumination coverage previously requiring multiple lamps, thereby reducing device complexity while maintaining comprehensive illumination.
2Illumination intensity
If two sets of lamps are used to illuminate upper and lower regions respectively, then illumination coverage is improved, but cost increases
Solution Approach 1:
The patent combines the functions of multiple lamps into a single lamp by integrating multiple irradiation parts within one lens structure. This merging reduces the total number of components, simplifies manufacturing processes, and lowers overall cost while achieving the same illumination coverage that previously required separate lamp assemblies.
3Device complexity
If a single lamp is used, then device complexity and cost are reduced, but illumination coverage of both upper and lower regions deteriorates
Solution Approach 1:
Different parts of the lens are designed with different optical properties - the first irradiation part has a larger beam angle for wide upper region coverage, while the second irradiation part has a smaller beam angle for focused lower region illumination. This local quality differentiation enables a single lamp to effectively illuminate both upper and lower regions with appropriate light distribution for each area.

Function Achieved in This Case
Simplifies the lighting arrangement and reduces costs by using a single lamp to illuminate both areas effectively, improving brightness distribution and uniformity.
Implementation Method 1
the top of the lens has a concave space for accommodating the light source, a first irradiation part is formed on one side of the inner wall of the concave space, and the light emitting surface of the first irradiation part is arranged toward the shelf, so as to guide part of the light from the light source to irradiate to the upper area of the shelf

AI summary
A shelf lighting mechanism has a lamp arranged on the upper front of the shelf, the lamp has a light source and lens, the top of the lens has a concave space for accommodating the light source, a first irradiation part is formed on one side of the inner wall of the concave space, and the light emitting surface of the first irradiation part is arranged to guide light to irradiate the upper area of the shelf; the bottom and the other side of the inner wall of the concave space are formed with a second irradiation part, and the light emitting surface of the second irradiation part is arranged to guide the other part of the light from the light source to irradiate the lower area of the shelf. The upper and lower areas of the shelf can be illuminated simultaneously by one lamp.
