Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If incandescent bulbs are used for product lighting, then high luminosity is achieved, but heat emission increases which is undesirable with many products
Solution Approach 1:
The patent transitions from incandescent bulb technology to LED technology, fundamentally changing the light generation parameter from thermal radiation to electroluminescence. This parameter change enables high luminosity output while minimizing heat emission, as LEDs convert electrical energy directly to light with minimal thermal byproduct, resolving the contradiction between brightness and heat generation.
2Use of energy by moving object
If fluorescent tubes are used for product lighting, then energy efficiency is improved, but luminosity and flexibility are reduced
Solution Approach 1:
The patent advances from fluorescent tube technology to LED technology, changing the light generation mechanism from gas discharge with phosphor conversion to direct electroluminescence. This parameter change achieves superior energy efficiency while simultaneously providing higher luminosity output and greater flexibility in light distribution, eliminating the trade-off present in fluorescent systems.
3Device complexity
If standardized light sources are used, then device complexity is reduced, but adaptability to different products is limited
Solution Approach 1:
The patent implements dynamic controllability of LED light sources through electronic control systems. Each LED module can be independently controlled in terms of intensity, color temperature, and timing, allowing the lighting system to adapt to different product requirements without changing the physical light source configuration. This dynamic control provides flexibility while maintaining standardized hardware components.
Solution Approach 2:
The patent designs LED light sources that can serve multiple functions: they can provide illumination, create specific color effects, adjust intensity levels, and operate in different patterns (continuous, intermittent, synchronized). This multi-functionality allows a single standardized LED component to adapt to various product display needs, resolving the contradiction between standardization and versatility.

AI summary
The invention provides a product display system and a method for illuminating a product. The product display system 1′ comprises a product carrier (20, 4′) and a lighting device comprising a plurality of light sources (10), each having two or more LEDs of different light color, and a control device (26). The control device (26) can control the various light sources (10), and even the various LEDs in the light sources, in order, in this way, to achieve a different luminosity and/or light color per light source. Thus, a flexible and energy-efficient system is obtained, by means of which special light effects can be obtained, such as promoting products by means of very bright lighting, or increasing the appeal of a product by adapting the lighting color to the color of the product (14, 16). For this purpose, the control device (26) reads a product information carrier coupled to the product, and adjusts a light source which illuminates a place of the product carrier designed for the product on the basis of information read from the product information carrier.
