Solution Overview
Problem
Current shop window lighting systems face challenges such as limited space, the need for ladders to adjust fixtures, inability to judge lighting effects from a distance, inconsistent lighting levels due to varying daylight conditions, and the lack of dynamic and balanced lighting setups, which often result in over-lighting, energy inefficiency, and limited use of advanced lighting techniques like key and fill lighting.
Innovation Solution
A lighting system comprising a series of LED lighting units mounted on a slim carrier, oriented to project light patches in a transverse direction, allowing for individual control and creating a continuous illumination pattern with adjustable beam angles and color temperatures, enabling more flexible and energy-efficient lighting configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If spots are installed at a higher position to illuminate shop window, then lighting coverage is improved, but accessibility for adjustment becomes difficult requiring ladders
Solution Approach 1:
The patent transitions from traditional ceiling-mounted spots to a vertical linear arrangement of LED modules along the shop window frame. This dimensional change allows the lighting system to achieve high positioning for optimal illumination while remaining accessible at eye level for adjustment and maintenance.
Solution Approach 2:
The lighting system is divided into multiple independent LED modules that can be individually adjusted. Each module can be fine-tuned separately without requiring access to high positions, as the modular design allows for ground-level adjustment of individual segments.
2Illumination intensity
If high intensity light is used to overcome daylight reflections, then visibility in daytime is improved, but energy consumption increases significantly
Solution Approach 1:
The lighting system incorporates dynamic control capabilities with individual LED modules that can be independently dimmed or switched off. This allows the system to adapt intensity levels to ambient daylight conditions, using high intensity only when necessary and reducing consumption during periods of sufficient natural light.
Solution Approach 2:
The system enables continuous adjustment of lighting parameters including intensity and color temperature. By varying these parameters according to time of day, season, and weather conditions, the system maintains optimal visibility while minimizing energy consumption through adaptive control.
3Reliability
If static lighting devices are used, then reliability is improved, but ability to create dynamic lighting scenes is limited
Solution Approach 1:
The patent replaces mechanical moving parts with electronically controllable LED modules. This substitution eliminates mechanical failures while enabling dynamic lighting scenes through electronic control, achieving both high reliability and versatility simultaneously.
Solution Approach 2:
The system can create dynamic lighting effects by periodically switching individual LED modules on and off or varying their intensity in sequences. This periodic electronic control enables animated lighting scenes without any mechanical movement, maintaining reliability while adding versatility.
4Illumination intensity
If narrow beam spots are used to increase brightness, then illumination intensity is improved, but uniformity of lighting distribution deteriorates
Solution Approach 1:
The lighting system divides the illumination task into multiple narrow-beam LED modules arranged in a linear pattern. Each module provides focused brightness to a specific area, while the collective arrangement of multiple segments creates overall uniform lighting distribution across the shop window display.
Solution Approach 2:
The system combines multiple narrow beam outputs into a unified lighting pattern. By merging the focused beams from sequentially arranged LED modules, the system achieves both the intensity of narrow beams and the uniformity of distributed lighting across the display area.
