Conveyor Belt LED Lighting Solutions

Advanced Optical Design Inside the Extremely Rugged MR Series Case

Having spent the last two decades on some of the toughest industrial sites in Northern Canada, our team has frequently been asked to address challenges related to conventional HID as well as some newer generation LED lights when used as Conveyor Belt Lights.

Frequent lamp and ballast replacements, poor lighting quality, high power consumption, susceptible to impact and vibration damage, a poor color rendering index, as well as excess power consumption, were some of the main concerns with older HID lights. Upgrading to certain LED products could address a few of the issues, but many systems are not designed to withstand the harsh environment, do not deliver optimize lighting distribution, and can rely on the substantial tilting of the light engines creating a challenge with excessive glare for the operators and non-compliance with basic Dark Sky guidelines were lighting beyond the horizon is prohibited.

Standard: Illuminating conveyor belts and adjacent walkways with conventional HID as well as most standard LED luminaires is typically achieved by installing a light fixture every 6 meters.

Nemalux: The use of advanced optics can allow for 12 meters spacing and deliver a 50% reduction in overall quantities, generating substantial cost and energy savings.

Using Nemalux’s solid-state MR Series as the base platform for the application, we can address all outlined challenges with the existing solutions, while providing a Made in Canada product to our industrial customers in the Americas.

Nemalux MR Series industrial LED luminaire with many mounting styles and optical profiles

The high-pressure die-cast aluminum housing with marine grade alloy as well as polycarbonate lenses creates an enclosure that can withstand impact and constant vibration. Mounting brackets designed to carry substantially heavier LED lights prevent stress fractures and breaks. Stainless steel fasteners are secured in place with thread locker to prevent loosening while allowing access for future upgrades.

LEDs and power supplies are rated for over 60,000 hours of operation prior to experiencing a 20% reduction in light output and can withstand ambient temperatures of – 40°C to + 55°C.

Optional 3,000K LEDs with a high color rendering index as well as full cut-off perimeter rings offer a fully Dark Skye compliant system when used in combination with our non-adjustable brackets.

MR pole mounts allow the installation of our lights with a 0° tilt while internal Type 1 secondary optics enable pole spacing of up to 12m when targeting 40-50lux on walkways. In addition, the textured/frosted protective lens of the MR substantially improves visual comfort for operators while eliminating the need to tilt the light engines.

In summary, reducing power consumption, reducing the overall number of lights and maintenance costs does not need to come at the cost of visual comfort and operator satisfaction. A cost-effective solution from Nemalux can address most challenges connected to older HID technology and less refined LED options on the market.
