Floor-Mounted Laser Lighting System with Ceiling Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems require the installation of lighting fixtures on ceilings to provide lighting for target spaces, which limits flexibility and ease of installation.
Innovation Solution
A lighting system comprising a light source unit with a laser light source and a light-distributing member that reflects and transforms the incident light into a different light distribution, allowing for lighting to be provided without any lighting fixtures on the ceiling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lighting fixtures are installed on the ceiling to provide lighting for the target space, then the lighting function is achieved, but the installation flexibility and ease are reduced
Solution Approach 1:
The patent extracts the light source from the traditional ceiling-mounted fixture housing and positions it on the floor, separating the lighting function from the ceiling installation requirement. This allows the lighting system to be installed without ceiling access while still achieving the lighting effect.
Solution Approach 2:
Instead of the conventional approach of installing light sources on the ceiling to illuminate the target space, this patent inverts the installation location to the floor and uses a reflective surface on the ceiling to redirect the light downward, achieving lighting from the opposite direction.
2Illumination intensity
If lighting fixtures are installed on the ceiling, then effective light distribution is achieved, but the device complexity and installation requirements increase
Solution Approach 1:
The patent introduces a reflective surface (intermediary element) on the ceiling to redirect light from the floor-mounted source to the target space. This mediator enables effective light distribution without requiring direct installation of fixtures on the ceiling.
Solution Approach 2:
The patent inverts the conventional lighting direction by placing the light source on the floor and using ceiling reflection to achieve downward illumination, simplifying installation while maintaining lighting effectiveness.
3Illumination intensity
If traditional lighting fixtures are used on the ceiling, then the lighting function is provided, but the aesthetic appeal and design flexibility are limited
Solution Approach 1:
By inverting the installation location from ceiling to floor, the patent removes visible fixtures from the ceiling, creating a cleaner aesthetic appearance while maintaining the lighting function through the reflective surface.
Solution Approach 2:
The patent extracts the visible fixture components from the ceiling area and relocates them to the floor, separating the functional lighting element from the aesthetic ceiling space while using a reflective surface to bridge the two.
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
Enables flexible and easy installation of lighting by providing lighting for target spaces without the need for ceiling-mounted fixtures, while maintaining effective light distribution and aesthetic appeal.
Implementation Method 1
The light-distributing member has a function of reflecting incident light that has been emitted as a beam of light from the light source unit toward a target space
Data Source
AI summary
A lighting system includes a light source unit and a light-distributing member. The light source unit includes a laser light source. The light-distributing member has the function of reflecting incident light that has been emitted as a beam of light from the light source unit toward a target space. The light-distributing member transforms the incident light into lighting light having a different light distribution property from the incident light and distributes the lighting light over the target space.
