CHANGING OF THE LIGHT DISTRIBUTION PATTERN BY ROTATIONAL ADJUSTMENT OF ASYMMETRICAL OPTICS
To date, most LED light fixtures emulate the form factor developed for light forces of the pre-LED era.
Whether it is about Aisle Lighters (High/Lowbay fixtures), Façade or Billboard Lighting, Area Lighting, etc., most LED light fixtures follow the form factor of luminaires that were designed decades ago for HID or fluorescent lamping.
This approach disregards the inherent nature of LEDs, which is all about plurality of light sources.
In most high wattage LED luminaires there’s a plurality of light emitting diodes, or COBs, which themselves incorporate a plurality of these diodes.
Plurality of the light-sources provides for the ability of shaping and aiming the light emitted by the individual sources within a luminaire.
Based on this principle, one can produce a single luminaire which can interchangeably recreate any of the Luminous Distribution Patterns as defined by IES, as well as countless other distribution patterns which best suit your particular application, or to adjust the pattern should field conditions at your project temporarily or permanently change.
The patterns can be pre-set by PRECILUX during the manufacturing process, or can be field adjusted prior to or after installation at the project site. The adjustment does not require any tools.
This principle provides for significantly improved uniformity, the usage of fewer luminaires, and for energy savings.
The principle is highly effective in lighting segments, such as
Aisle Lighting (High/Lowbay), Façade and Billboard Lighting, Parking Garage Lighting, Area Lighting, etc.
The principle is set forth in, and is protected by various patents in the US, the EU and elsewhere.
