Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lighting systems lack flexibility in adjusting the angles of LED arrays, which limits their ability to provide optimal lighting distribution and control, particularly in applications requiring directional lighting.
Innovation Solution
The development of a lighting system with extended arrays of LED light engines positioned at angles relative to each other, coupled to adjustable support surfaces within a housing structure, allowing for adjustable angles and independent dimming control of upward and downward lighting through the use of LED driver circuits and mechanisms like servo-motors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED arrays are fixed at standard angles, then manufacturing and installation are simple, but lighting distribution flexibility is limited
Solution Approach 1:
The patent implements adjustable support surfaces that can change their orientation angles dynamically. The support surfaces are designed to be reconfigurable, allowing LED arrays to be positioned at different angles relative to the housing structure, transforming a static system into a dynamic one that adapts to various lighting requirements.
Solution Approach 2:
The lighting system is divided into modular components: LED arrays, support surfaces, and housing structure. Each support surface can be independently adjusted, and each LED array can be positioned separately, allowing granular control over lighting distribution without requiring complex overall system redesign.
2Ease of operation
If upward and downward lighting are controlled by separate LED drivers, then independent dimming control is achieved, but system complexity increases
Solution Approach 1:
The lighting system is segmented into upward-facing and downward-facing LED arrays, each controlled by separate LED driver circuits. This segmentation allows independent dimming control for each direction, enabling flexible lighting scenarios without requiring complex integrated control systems.
Solution Approach 2:
The separate LED drivers provide multi-functionality by enabling independent control of upward and downward lighting. The same driver architecture can be used for both directions, and the system can operate in various modes (upward only, downward only, or both simultaneously with independent dimming levels).

Implementation Method 1
A light-emitting diode (LED) is a semiconductor diode that emits light when an electrical current is applied in the forward direction of the device
Implementation Method 2
As the current passes through the LED device, the materials that makes up the junction react and light is emitted
Implementation Method 3
The housing structure includes, for example, opaque surfaces and diffuse surfaces (lenses). Preferably, the extended arrays of LED light engines emit both upward and downward lighting through the diffuse surfaces of the housing structure
