EverLast Lighting of Full Spectrum Solutions collaborated with CLTC to develop the BioLume Series, which includes garage, shoebox, wall pack, and canopy fixtures. The patent-pending lighting series is a collection of hybrid, adaptive luminaires that use an induction lamp and amber LEDs, coupled with occupancy sensor controls.

When a space is vacant, the LEDs emit amber light (left). When the sensor is triggered, the induction lamp turns on (center) to provide white light for enhanced visual acuity and security (right). The fixture is predicted to operate about 50-75% of the time in low mode, producing energy-efficient light that will not interfere with light-sensitive living systems.

Light at Night

The BioLume Series saves energy while addressing concern within the lighting industry that exposure to certain light levels and blue spectral content at night might create biological disturbances or imbalances in certain species.

LED Development Process

Working with in-house design and prototyping tools, CLTC engineers started with a standard EverLast fixture and began a design exploration process to add LEDs as a second source. Iterations of shapes and configurations were proposed until the right combination of form and function was achieved.

A CAD and simulation tool package was used to model and refine the heat sink and simulate its performance. CLTC staff then used in-house CNC machining capabilities to shape the first versions of the heat sink, lens, and circuit board. 

LED Selection

CLTC partnered with Philips Lumileds to select specialized amber LEDs for this project. The project team specified Rebel Coated Phosphor Amber LEDS that would provide enough light for egress but accomplish the spectral sensitivity goals.

Next Steps

The BioLume will debut at LightFair 2011 and will be in production in summer 2011. This fixture represents an emerging market in multisource, multispectrum combinations for niche applications where health and wellness concerns of living systems play an important role in lighting design.
