Segmented LED Lamp Control for Expanded Color Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lamps with 8-bit color depth struggle to improve visual effects due to limitations in physical color bit depth of each LED bead, necessitating new methods to enhance visual performance.
Innovation Solution
The LED lamp is logically divided into multiple illuminating segments, each comprising LED beads, which are connected to address coder-decoders forming logic units. These units are synchronized to expand the color channel bit depth through a combination of address coder-decoders, allowing for more diversified and subtle color display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If 8-bit color depth is used for each LED bead, then the control system remains simple and cost-effective, but the visual effect and color diversity are limited
Solution Approach 1:
The LED lamp is divided into multiple illuminating segments, each controlled by a separate address coder-decoder. This segmentation allows each segment to operate with 8-bit color depth while the combination of segments achieves higher effective color depth, resolving the contradiction between maintaining simple individual control and achieving diverse visual effects.
Solution Approach 2:
The patent transitions from increasing color depth within a single LED bead to expanding color depth across multiple spatial dimensions (multiple segments). By combining the color outputs of multiple segments controlled by multiple address coder-decoders, the system achieves higher effective color depth without increasing the bit depth of individual LED beads.
2Loss of information
If physical color bit depth of each LED bead is increased, then color diversity and visual effect are improved, but manufacturing complexity and cost increase
Solution Approach 1:
Instead of manufacturing LED beads with higher physical color bit depth, the patent segments the lamp into multiple illuminating segments, each with standard 8-bit color depth LED beads. The combination of these segments provides the effective higher color depth, avoiding the manufacturing complexity of producing high-bit-depth LED beads.
Solution Approach 2:
The patent uses multiple copies of standard 8-bit color depth LED beads arranged in segments. By combining these copies through multiple address coder-decoders, the system achieves the effect of higher color depth without needing to manufacture complex high-bit-depth LED beads, thus maintaining ease of manufacture.
3Illumination intensity
If multiple address coder-decoders are used to expand color depth, then visual effect is improved, but the number of control components increases
Solution Approach 1:
The control system is segmented into multiple address coder-decoders, each managing a specific illuminating segment. This segmentation distributes the control complexity across multiple simple units rather than requiring one complex high-bit-depth controller, achieving improved visual effect while keeping individual control components relatively simple.
Solution Approach 2:
Multiple address coder-decoders are merged to work together in controlling the LED lamp. Each address coder-decoder contributes to the overall color output by controlling its segment, and their combined effect achieves higher effective color depth and improved visual effect without requiring any single component to be overly complex.

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 front-to-rear 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 bits in color depth of every color channel, or indirect expansion of color channels. Because current LED beads have a small superficial area, through such expansion, the visual effect of the LED lamp is improved, and more diversified and subtle colors are easily displayed.
