LED Lamp Segment Control for Expanded Color Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lamps with 8-bit control cannot significantly improve the physical color depth of each LED bead, limiting the visual effects they can achieve.
Innovation Solution
The LED lamp is logically divided into multiple illuminating segments, each with n LED beads, connected to address coder-decoders that form LED logic units, allowing synchronous control of color channels across these units, effectively expanding the color depth through a combination of logic units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 8-bit binary data is used to control each color channel of LED beads, then the device complexity is reduced and ease of operation is improved, but the visual effect and color depth are limited
Solution Approach 1:
The LED lamp is divided into multiple illuminating segments (first illuminating segment with n LED beads, second illuminating segment with n LED beads, etc.), where each segment is controlled by a separate address coder-decoder. This segmentation allows the system to maintain simple 8-bit control for each segment while achieving expanded color depth through the combination of multiple segments in backward-forward cascade connection.
2Illumination intensity
If the physical color depth of each LED bead is increased, then the visual effect is improved, but the device complexity and manufacturing difficulty increase significantly
Solution Approach 1:
Address coder-decoders are introduced as intermediary devices between the control system and LED beads. Each address coder-decoder receives simple binary data and translates it into expanded color control signals for its associated LED beads. This intermediary approach enables color depth expansion without requiring complex control circuits within each LED bead itself.
Solution Approach 2:
Multiple identical illuminating segments with the same number of LED beads (n beads each) are created and connected in cascade. Each segment is a copy of the basic unit, controlled by its own address coder-decoder. This copying strategy allows the system to achieve expanded color depth through the combination of multiple identical units rather than modifying individual bead complexity.
3Area of stationary object
If more LED beads are added to increase visual effect, then the illumination coverage is improved, but the control complexity and data processing requirements increase
Solution Approach 1:
The LED lamp is divided into multiple illuminating segments (first illuminating segment with n LED beads, second illuminating segment with n LED beads, etc.), where each segment is controlled by a separate address coder-decoder. This segmentation allows the system to maintain simple 8-bit control for each segment while achieving expanded color depth through the combination of multiple segments in backward-forward cascade connection.

AI summary
An LED lamp for improving a visual effect includes: a first illuminating segment and a second illuminating segment with the same specifications, a first address coder-decoder for enabling n LED beads in the first illuminating segment to constitute a first LED logic unit, and a second address coder-decoder for enabling n LED beads in the second illuminating segment to constitute a second LED logic unit. The first LED logic unit is in backward-forward cascade connection to the second LED logic unit; and the LED lamp further synchronously controls every color channel of all the LED beads in the first LED logic unit and the second LED logic unit through the first address coder-decoder and the second address coder-decoder. The present disclosure realizes an equal effect of color depths of every color channel, or indirect expansion of color channels.
