Shelf Lamp Optical Element Design for Dual-Layer Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelf lighting systems fail to provide uniform illumination to both upper and lower layers of goods on shelves, leading to inadequate display lighting and increased equipment and energy costs when trying to highlight the side closest to the user.
Innovation Solution
A shelf lamp design featuring a lamp holder with a circuit board, light source, and optical elements that direct light to illuminate both sides of the laminate, using a combination of optical lenses or reflector cups to deflect light and achieve optimal illumination angles, with a strip lens or revolved body configuration for efficient light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single-row light source with beam splitting lens is used to illuminate upper and lower laminates, then light splitting function is achieved, but the lamp body becomes large in size and cannot ensure good illumination of goods on upper and lower layers
Solution Approach 1:
The patent divides the illumination function into two separate light sources: one light source for illuminating the upper laminate and another light source for illuminating the lower laminate. Each light source is independently positioned and directed, allowing the lamp body to maintain a compact size while ensuring adequate illumination intensity for goods on both upper and lower layers without requiring a large beam splitting lens system.
2Illumination intensity
If additional light sources are added for accent lighting to highlight the display side of goods, then purchase desire is increased, but equipment cost and electricity cost increase
Solution Approach 1:
The patent applies local quality by directing light from each light source specifically toward the display side of goods on the respective laminates. The upper light source is positioned and angled to illuminate the front-facing goods on the upper laminate, while the lower light source similarly targets the display side of goods on the lower laminate. This localized illumination approach highlights the most visible portions of products without requiring additional accent lighting fixtures, thereby maintaining energy efficiency while enhancing visual appeal.
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 simultaneous and effective illumination of both upper and lower sides of the laminate, enhancing display lighting effects and reducing equipment size while maintaining energy efficiency.
Implementation Method 1
the first optical element is arranged in the light emitting direction of the first illumination light to deflect upward at least part of the first illumination light
Implementation Method 2
at least part of the light from the light source above the interface is projected above the laminate as an first illumination light which illuminates the upper side of the laminate, and at least part of the light from the light source located below the interface is projected below the laminate
Data Source
AI summary
A shelf lamp includes a lamp holder, a circuit board, a light source and a first optical element; the first optical element is arranged in the light emitting direction of the first illumination light to deflect upward at least part of the first illumination light; the connection line between the light source and the lower edge of the outer panel is the C direction, and the included angle between the C direction and the vertical downward direction is greater than 45°. The shelf lamp and the identification plate lamp can simultaneously illuminate the upper and lower side areas of the laminate, and achieve different lighting effects. When they are installed on each laminate, the goods on the laminate obtain the illumination of different angles and different effects in two directions.
