Ledil LED Lens BRIANNA: Redefining Office Lighting Comfort
Leave a message
In the realm of office lighting, glare control has long been a central challenge in optical design. Traditional anti-glare solutions often require compromises between fixture size, optical efficiency, and visual comfort; however, the optical innovations embodied in the BRIANNA series are changing this paradigm.
I. Glare Control from an Optical Principles Perspective
Glare is, in essence, a phenomenon of visual discomfort caused by excessive brightness or high contrast within one's field of view. In optical design, controlling glare-specifically manifested as achieving a low Unified Glare Rating (UGR), such as UGR ≤ 19-requires the precise management of two key parameters:
First, the surface luminance of the light source;
and second, the angular distribution of the light rays.
Through a patented optical design, the Ledil LED Lens BRIANNA series achieves a synergistic optimization across both of these dimensions. It not only significantly reduces the direct luminance emitted from the light source's surface but also precisely controls the trajectory of the light rays, thereby guaranteeing a comfortable visual experience at the fundamental level of optical physics.
BRIANNA employs a unique curved surface structure capable of redistributing the light emitted by point-source LEDs to create a uniform luminous surface. The brilliance of this design lies in its ability to significantly lower the peak luminance on the fixture's surface-a critical factor in mitigating direct glare-while simultaneously maintaining high optical efficiency.
II. Design for Optical Compatibility
Although BRIANNA serves as a complete, standalone anti-glare solution, its design was conceived with the specific intent of ensuring synergy with other optical systems.
For instance, it shares the same LED spacing design as the DAISY series, meaning these two optical systems can integrate seamlessly within a single lighting platform. While BRIANNA provides the foundational, low-glare ambient lighting environment, DAISY can serve as a complement for localized accent lighting; their matched optical characteristics ensure that no jarring optical discontinuities or "breaks" occur between the two.
III. BRIANNA's Breakthrough Innovations
The Ledil LED Lens BRIANNA utilizes a patented optical design to achieve a quantum leap in optical performance within a compact form factor. Its core breakthroughs include:
1. Breakthrough in Surface Uniformity
Through a precision-engineered optical curved surface design, BRIANNA achieves exceptional uniformity in the light emitted from its top surface. This means that, given the same mounting height and spacing, the work surface benefits from a smoother light transition, significantly reducing the need for frequent pupil adjustment caused by abrupt shifts between light and shadow.
2. Precise Control of Light Distribution
BRIANNA precisely controls the intensity distribution of light at angles exceeding 37°-the critical zone for potential glare-thereby serving as a key factor in minimizing direct glare. Traditional designs often attempt to control glare by increasing the shielding angle, a method that typically comes at the cost of light output efficiency; BRIANNA, however, resolves this issue at the very source-through its optical structure-while simultaneously maintaining high efficiency.
3. Suppression of Multiple Reflections
In office environments, reflective glare-generated by surfaces such as computer screens and glass partitions-also impacts visual comfort. BRIANNA's light distribution profile has been optimized to ensure that the angle of incidence within primary work areas is more appropriate, thereby reducing the probability of primary reflective glare occurring at the source.
IV. Verified Performance
In a standard office lighting environment (illuminance of 500 lx, mounting height of 2.6 meters), BRIANNA achieved an exceptional performance rating of UGR ≤ 19. This places its glare control within a range classified as "barely perceptible" to "perceptible but comfortable."
Crucially, this low level of glare is achieved without compromising luminous efficacy; the system maintains an efficiency level that remains at the forefront of the industry.
The Ledil BRIANNA lens offers two beam angle options-75° and 60°-each tailored to suit different installation scenarios. The wider 75° beam allows for greater spacing between luminaires while maintaining a low UGR, thereby reducing the total number of fixtures required. Conversely, the narrower 60° beam is better suited for installations in high-ceiling spaces, preventing excessive light dispersion.
Furthermore, BRIANNA offers a specialized wall-washing solution capable of producing a uniform, fluid arc of light. While satisfying fundamental anti-glare requirements, this solution simultaneously provides the space with accent lighting that adds a rich sense of visual depth and layering.
