Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shop window lighting systems face challenges such as limited space, the need for ladders to install fixtures, difficulty in judging lighting effects, inconsistent lighting levels due to varying daylight conditions, and the inability to create dynamic or balanced lighting scenes with static solutions.
Innovation Solution
A lighting system comprising multiple LED-based lighting units mounted on a slim carrier, configured to project light patches at different angles and intensities, allowing for adjustable and dynamic lighting patterns with key and fill lights, and the ability to adapt to ambient light conditions, while minimizing thermal load and visual impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If spots are installed at a higher position out of reach for arms, then the lighting coverage is improved, but the risk of falling and disturbance to the scene increases
Solution Approach 1:
The patent transitions from traditional ceiling-mounted spotlights to a handheld lighting device that operates in a different spatial dimension. The device includes a handle for hand holding and an elongate body extending from the handle, allowing the operator to position the light source at various heights and angles without requiring access to ceiling-level installation positions. This dimensional shift eliminates the need for ladders while maintaining effective lighting coverage.
2Illumination intensity
If narrow beam spots with high intensity are used, then the brightness on the display is increased to reduce reflections, but the energy consumption increases and the scene becomes overlit during lower daylight conditions
Solution Approach 1:
The patent incorporates a dimmable light source that can be adjusted in intensity, transforming the static high-intensity spotlight into a dynamic lighting system. The controller allows adjustment of the light output to match ambient conditions, enabling the operator to use lower intensity during daytime or overcast conditions and reserve high intensity only for necessary moments, thereby reducing overall energy consumption while maintaining display visibility.
Solution Approach 2:
The light source parameters (intensity, color temperature) are made variable rather than fixed. The dimmable capability allows continuous adjustment of luminous output, and the ability to select different color temperatures enables adaptation to various ambient lighting conditions. This parameter variability allows optimization between brightness requirements and energy consumption based on real-time environmental factors.
3Ease of operation
If the person doing the lighting is too close to the scene, then the positioning and aiming can be adjusted, but the visual end result cannot be judged properly
Solution Approach 1:
The handheld lighting device serves as an intermediary tool that bridges the gap between close-up adjustment and distant evaluation. The extended elongate body with handle allows the operator to position the light source precisely while maintaining a working distance from the display. The device's design enables adjustment of lighting parameters at close range while the operator can periodically step back to evaluate the overall effect, using the device as a portable, movable light source rather than a fixed installation.
4Device complexity
If the same lighting solution is used 24/7, then the setup is simple, but the energy consumption increases and the lighting quality does not adapt to varying ambient conditions
Solution Approach 1:
The patent transforms the static 24/7 fixed lighting setup into a dynamic, adaptable system. The dimmable light source and controller enable real-time adjustment of intensity and color temperature based on ambient conditions. The system can be configured to automatically or manually adjust lighting parameters throughout the day, using lower intensity during daytime hours and higher intensity only when necessary, thereby reducing energy consumption while maintaining display effectiveness.
