Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ambient light lighting devices are limited in their ability to cover large spaces efficiently and project different types of light, such as accent, wall washer, or task lighting, while maintaining control over color and intensity without shadows or glare, and require multiple installations.
Innovation Solution
A lighting device comprising a bar with a longitudinal body, light strips, and superimposed diffusers, along with a PCB electronic board and power supply module, allowing for independent control and programming of light intensity and color across multiple bars that can be connected linearly to cover large areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple point lighting devices are installed to cover large rooms, then the coverage area is improved, but the device complexity and installation cost increase
Solution Approach 1:
The lighting system is divided into modular bar units that can be independently installed and connected. Each bar contains integrated light strips, diffusers, and control electronics, allowing the system to be segmented into manageable sections that can be extended linearly to cover large areas without requiring multiple separate point lighting devices
Solution Approach 2:
Multiple functional components are merged into a single bar unit: light strips, diffusers, electronic boards, and power supplies are integrated into one cohesive structure. This consolidation allows one bar device to perform the function of multiple separate lighting devices while reducing overall system complexity
2Illumination intensity
If point lighting devices are used for ambient light projection, then the basic visibility is improved, but the ability to project different types of light (accent, wall washer, task lighting) is limited
Solution Approach 1:
The lighting system incorporates programmable control that allows dynamic adjustment of light output. Different light types (ambient, accent, wall washer, task lighting) can be projected by programming the electronic board to control the light strips in various patterns and intensities, transforming a static lighting device into a versatile, adaptable system
Solution Approach 2:
The bar lighting device is designed to perform multiple functions through a single unit. By integrating controllable light strips and diffusers, the device can provide basic visibility, accent lighting, wall washing, and task lighting capabilities, making one device capable of replacing multiple specialized lighting devices
3Area of stationary object
If light is projected to illuminate large rooms, then the coverage is improved, but shadows and glare are produced
Solution Approach 1:
Diffusers are introduced as intermediary elements between the light strips and the environment. These diffusers scatter the light from the light strips, transforming direct light into diffuse light that illuminates large areas without creating harsh shadows or glare, while still maintaining coverage

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient projection of ambient light with adjustable color and intensity across large spaces without shadows or glare, reducing the need for multiple installations by allowing bars to be connected and programmed independently.
