Light Engineering

Light Reimagined.

RSL doesn’t just manufacture products, we engineer and create solutions. We are the leader in remote source light engineering, having revolutionized fiber optic illumination and LED smart lighting for military and commercial industry. In fact, our lighting technology introduced the concept of removing hazardous electricity from the actual lighted area, improving safety and cost in diverse conditions.

But while we’re proud of our expertise, our practicality is integral to our success. In engineering, we find the biggest problem isn’t coming up with ideas, it is interfacing all the elements. Variables as seemingly small as the epoxy used in a component can impact functionality, and our whole-system approach anticipates that for more efficient, durable design.

Looking Forward: Adapting Technologies to Solve Future Problems

Imagination thrives in the convergence of lived experience, knowledge of systems, and pursuit of the ideal. RSL doesn’t want to re-invent the wheel—we want to leverage existing and emerging technologies to solve real problems.

While we design solutions for today’s world, we keep a vigilant eye on the future. In the not-so-distant past, it was hard to imagine lighting a hazardous environment without the risks of electricity or servicing topside lights from the safety of the ship’s cabin. But RSL is the pursuer of possibilities; we work to identify new technologic advancements and apply them in practical, safe ways. We take one of the world’s most basic and omnipresent energies— light— and find waysto harness it to solve problems.

A System Approach

RSL engineering is more than just light bulbs. Our proprietary technology is underpinned by a multifaceted approach which requires four key aspects to work individually and—most importantly—with one another as a whole system.

Light Source Technology

We love light.

All kinds of light. Metal halide lamps, LEDs, and especially laser diodes get us going. But all light sources come with unique challenges and opportunities, which we harness in inventive ways like:

Thermal Management: Light energy produces heat, and the heat production process is different for each type of light source. Since excessive heat reduces system life expectancy and can impact other system components, RSL manages heat accordingly, building systems as unique as the light they emit.

Chromaticity: Especially in marine environments, the “color” of the light must meet specific requirements according to international navigation Rules to Prevent Collison at Sea (72 COLREGS). RSL has developed both metal halide and LED light systems that consistently meet this narrow and unique chromaticity range.

Packaging for Durability: When it comes to housing the light unit, RSL has considered various environmental and operational factors including vibration, shock, electromagnetic interference, temperature cycling, and salt spray to design units that are reliable in adverse environments.
