Optimizing Indoor LED Lighting Design for Illumination and Communication: A Scientific Approach to Smart Lighting Solutions
Introduction
The evolution of LED technology has transformed indoor lighting from a simple utility into a multifunctional system capable of providing both high-quality illumination and high-speed data communication. As the demand for efficient, comfortable, and intelligent lighting grows, the design and distribution of LED sources have become critical to performance. Recent research highlights how optimized LED layouts can simultaneously enhance visual comfort and support visible light communication (VLC). This article explores key findings from a 2025 study on LED distribution design and introduces Shenzhen Benwei Lighting as a provider of advanced, scientifically informed lighting solutions.
The Dual Role of LED Lighting: Illumination and Communication
Modern LED systems do more than light up spaces-they can also transmit data through visible light waves, a technology known as VLC or LiFi. This dual functionality offers advantages such as immunity to electromagnetic interference and high bandwidth. However, achieving both uniform illumination and stable signal coverage requires careful planning of LED placement and technical parameters.
Traditional LED layouts, such as rectangular arrays, often lead to uneven light distribution and fluctuating signal quality. To address this, researchers from Baise University proposed a honeycomb-structured LED distribution-a design that improves both lighting uniformity and communication reliability.
Key Parameters for Optimized LED Performance
The study identified three critical factors that influence lighting and communication performance:
LED Half-Power Angle: This angle defines the beam spread of an LED. A smaller half-power angle (e.g., 15°) results in concentrated light with high peak intensity but significant fluctuations in illumination. A larger angle (e.g., 35°) produces a more uniform distribution but may reduce peak brightness.
Spacing Between Adjacent LEDs: The distance between light sources affects overlapping illumination zones. Increasing spacing within an optimal range can reduce fluctuations, but exceeding a threshold leads to "hot spots" and "dark zones."
Mounting Height: The vertical distance between the LED plane and the illuminated or receiving surface plays a crucial role. Reducing height without adjusting other parameters can amplify unevenness in both light and signal distribution.
Data-Backed Insights from Simulation Experiments
The research team simulated various configurations using a room model that measures 9 m × 9 m × 3 m and features 36 honeycomb-arranged LEDs:
With a half-power angle of 15°, spacing of 1.2 m, and height of 2.2 m, the illuminance ranged from 138 lux to 551 lux-a fluctuation of 413 lux.
Increasing the half-power angle to 35° under the same conditions reduced the fluctuation to 331 lux, significantly improving uniformity.
Similarly, for VLC performance, a half-power angle of 15° resulted in a signal-to-noise ratio (SNR) variance of 12 dB, while 35° reduced it to 10 dB, ensuring more stable data transmission.
These results confirm that no single parameter can guarantee optimal performance. A balanced approach that concurrently optimizes angle, spacing, and height is essential.
