研究目的
To propose a method to accurately calculate the illuminating distribution on the ceiling based on the super-positions of the two side-wall LED system and to design the LED wall systems with high uniformity of backlight illumination for several configurations.
研究成果
The paper presents a new model and approach for designing LED wall systems with high uniformity of backlight illumination. The proposed method provides a convenient and time-saving way to design LED backlight systems with high uniformity of illumination, which is beneficial for practical efficient lighting and the LED lighting manufacturing industry.
研究不足
The study focuses on the theoretical analysis and design of LED lighting systems for high uniformity illumination. Practical implementation and testing in real-world scenarios are not covered.
1：Experimental Design and Method Selection:
The study starts from the non-uniform illumination distribution of two LED sources and investigates the dependences of the uniformity ratio on the height of the LED source and the length of the ceiling. A secondary optical lens is added after the LEDs to modulate the light pattern for achieving high uniformity illumination.
2：Sample Selection and Data Sources:
The study considers the illumination distribution on the ceiling from two LED sources mounted on the side-walls.
3：List of Experimental Equipment and Materials:
LED sources with a secondary optical lens.
4：Experimental Procedures and Operational Workflow:
The light distribution on the ceiling is calculated for different configurations of LED sources and ceiling dimensions. The redistributed factor of the illumination through the lens is calculated.
5：Data Analysis Methods:
The illumination distribution is analyzed based on the super-positions of the two side-wall LED system and the redistributed factor through the lens.
