Indirect Lighting Fixture with Parallel LED Platforms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting fixtures often result in direct lighting that can cause undesirable dazzle and shadows, and lack versatility in configuration to match various interior design schemes and architectural styles.
Innovation Solution
A modular lighting system featuring two parallel platforms with LED light sources and control lenses, where light from one platform is reflected off a nearby surface to provide indirect lighting, allowing for adaptable configurations and aesthetically pleasing installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If direct lighting is used to illuminate the environment, then the lighting intensity is sufficient, but it causes undesirable dazzle and shadows
Solution Approach 1:
The patent introduces an intermediary reflective surface (wall, ceiling, or floor) between the light source and the environment. Light is first directed toward this intermediate surface, which then reflects the light into the target area. This mediator eliminates direct line-of-sight illumination, thereby removing the harmful dazzle and shadow effects while preserving adequate lighting intensity through the reflected path.
2Ease of manufacture
If a fixed lighting fixture configuration is used, then the manufacturing is simple, but it lacks versatility to match various interior design schemes
Solution Approach 1:
The lighting system is divided into separate modular components: a light source module, a reflective surface module, and a mounting module. Each component can be independently manufactured and configured. The light source can be positioned at different heights and angles, and the reflective surface can be selected from various materials and orientations, allowing the same basic design to adapt to multiple interior design schemes while maintaining manufacturing simplicity through standardized components.
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
The system effectively reduces dazzle and shadows by providing indirect lighting, enhances ambiance, and offers versatile configuration options to harmonize with diverse design schemes and architectural styles while maintaining efficient power consumption and recyclability.
Implementation Method 1
Light originating from the first light source, preferably LED board(s), is transmitted from the first housing through a first control lens
Implementation Method 2
Light originating from the first light source... is reflected from a nearby surface to provide indirect lighting to the surrounding environment
Implementation Method 3
The second light source, preferably also LED board(s), projects light through a second control lens and directly from the second housing across the separation distance toward the first housing
Implementation Method 4
the first housing reflects at least a portion of the light from the second light source, thereby to emit indirect lighting from the module
Data Source
AI summary
A lighting apparatus and system which employs light sources, preferably LED boards, situated in parallel housing platforms. Two lighting platforms are arranged in a spaced-apart relationship to provide indirect lighting to the surrounding environment. Each platform mounts a light source, such as a series of LED boards. Each LED board functions as an indirect lighting source. The first one of the platforms emits light toward a nearby architectural feature or surface (e.g., a room wall or ceiling) for reflection to the environment to be lighted. A second of the platforms emits light toward the first platform; the light emitted from the second platform is reflected from the first platform to the environment to be lighted.
