Luminaire Case Design
Nemalux uses marine-grade aluminum alloys with low copper content (copper-free) luminaire housings. They can withstand long-term exposure to chemicals and salt water and act as effective heatsinks. Powder coating and anodizing options further improve housing performance in tough environments. Our use of specialty powder coats and processes provides a mil-spec-compliant multi-layer coating meant to withstand simultaneous exposure to corrosive chemicals, UV, and saltwater. Safety is improved by designing luminaire cases around the specific requirements of LED technology and avoiding retrofits of legacy technology enclosures.
Vented Light Enclosures
Industrial enclosures experience substantial changes in the surrounding atmosphere, temperature, and humidity. Using pressure equalization vents, Nemalux light fixtures are sealed to IP66/67 while allowing the system to breathe. This reduces stress on components and dissipates excess humidity, serving to avoid the buildup of droplets on sensitive electronics.
Luminaire Mounting Hardware
As industry practices are evolving, the use of flexible mounting hardware is instrumental for an optimized installation process. Industrial grade brackets are not only designed to withstand severe vibration, impact, and chemical exposure and offer secondary safety points as means of fall protection, but they also need to allow optimized placement in new and existing facilities to reduce costs and deployment time. Nemalux’s standard catalogue includes an extensive range of brackets for specific fixture series, allowing for a substantial reduction of luminaire types on the final bill of material as well as streamlining the engineering, procurement, installation, and maintenance process. This represents a major competitive advantage in our addressable market segment.
LED Lighting
Nemalux selects high-quality diodes primarily from CREE, Samsung, and Nichia that are underpowered to reduce heat stress and premature aging of components. The longevity of LEDs is extended by reducing the current flow by 50-70% of the rated max value, which allows for implementation in harsh environments.
Metal Core Printed Circuit Boards (MCPCB)
MCPCBs are a vital part of heat transfer from the LEDs to the external case, allowing for greater temperature range and extended performance in industrial applications. Built-in redundancies account for a possible failure of individual diodes which allows for continuous operation and minimal change in the overall light output. The serviceability of Nemalux luminaries is a major benefit as this allows for future upgrades and field replacements. Our designs offer easy access to light engines and solder-free quick-connect components.
Secondary Optics
Located behind the external protective lens, secondary optics from LEDiL and other vendors provide greater flexibility during the lighting design and application process. Such devices shape the light, substantially reducing installation and operation costs. Using AGI32 and Dialux Evo design software, Nemalux designers can advise on optimal spacing and mounting heights based on project and facility needs.
Power Supplies
Programmable and hazardous location power supplies allow us to balance the approach between thermal management and efficiency. 0-10V dimmable power supplies are available for modifying illumination levels. L90 values are important indicators that have a substantial impact on the overall system reliability and should be considered carefully during the luminaire selection process. In high-output systems, the use of multiple power supplies allows for a portion of the luminaire to remain functional in case of an individual power supply failure.
Glare Reduction
Safety on industrial sites can not only be compromised by the absence of adequate illumination but also by excessive glare and light trespass. Selecting the appropriate mounting height, tilting angle and lens type are factors that have a substantial impact. Nemalux luminaires with a glare reduction lens and sharp cutoff are key in improving visual comfort and acuity.
Serviceability
Most Nemalux luminaires are designed with field serviceability in mind, allowing maintenance and upgrading options outside of the warranty period. Where conventional HID fixtures were designed with service in mind due to the shorter life expectancy of bulbs and ballasts, the emergence of LED technology has caused a shift to non-serviceable/sealed systems. This approach from other manufacturers has proven challenging in the past for industrial applications as rather valuable fixtures had to be discarded instead of a much more cost and environmentally-effective approach of changing aging components.
