Luminaire with Segmented LED Modules and Adjustable Reflectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting solutions for retail environments, such as supermarkets, fail to provide glare-free, efficient, and aesthetically pleasing illumination that effectively highlights attractive goods on shelves while minimizing light on lower-positioned standard goods, and are not cost-effective in production with minimal material usage.
Innovation Solution
A luminaire design featuring a double or single reflector base configuration with U-shaped second reflector bases and a cover acting as a heat sink, allowing for adjustable light distribution through interchangeable reflectors and an actuating device, ensuring optimal illumination on side surfaces and floor surfaces with reduced glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting solutions are used in retail environments, then illumination is provided, but glare is generated and light distribution is not optimized for highlighting attractive goods
Solution Approach 1:
The lighting system is divided into multiple LED modules arranged in a linear sequence, with each module containing individual LEDs that can be independently controlled. This segmentation allows different sections of the luminaire to direct light to different areas (attractive goods vs. standard goods), optimizing illumination distribution while minimizing glare in specific directions
Solution Approach 2:
Different regions of the luminaire are designed with different optical characteristics. Some LED modules are oriented to provide focused illumination on attractive goods at eye level, while others direct light to standard goods on lower shelves. This local differentiation of lighting quality achieves selective illumination without creating glare in customer viewing areas
2Quantity of substance
If existing luminaire designs are used, then light is emitted, but material usage is excessive and production costs are high
Solution Approach 1:
Multiple functional components are merged into integrated assemblies. The LED modules combine light-emitting elements, heat sinks, and optical directors in single units. The linear arrangement of modules allows shared mounting structures and electrical connections, reducing overall material usage and simplifying manufacturing processes while maintaining effective light distribution
Solution Approach 2:
The luminaire design uses standardized LED modules that can be configured in different orientations and arrangements to serve multiple lighting purposes (highlighting attractive goods, illuminating standard goods, providing ambient light). This modularity reduces the need for multiple specialized components, lowering material usage and production costs
3Adaptability or versatility
If traditional reflector configurations are used, then light is directed, but the ability to adjust light distribution for different shelf zones is limited
Solution Approach 1:
The luminaire incorporates adjustable components that allow the light distribution pattern to be modified. LED modules can be repositioned or reoriented along the linear arrangement, and optical directors can be adjusted to change beam directions. This dynamic adjustability enables adaptation to different shelf configurations and lighting requirements without complex fixed reflector systems
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 luminaire achieves glare-free, efficient light distribution that accentuates higher-positioned goods while minimizing light on lower surfaces, enhancing customer experience and reducing production costs through efficient material use and adjustable configurations.
Implementation Method 1
a cover (6) which acts as a heat sink
Implementation Method 2
a first reflector base (1) with a first reflector surface (R1)... a second reflector base (2) with a second reflector surface (R2)... the light emitted by the LED chips is directed onto the reflector bases and from there in a glare-free manner mainly onto one or both side surfaces (92), slightly onto the floor surface (91)

AI summary
The lamp (8) has a reflector surface (R1) provided at a reflector base (1) and a light i.e. LED. The reflector surface comprises an outline (12). The light is provided at another reflector base (2) with another reflector surface (R2). The later reflector base comprises lateral shield elements (21) between which the light is positioned. Inner surfaces of the shield elements are turned towards the light and proportionately form the latter reflector surface. The shield elements comprise an outer edge border, which represents another outline.
