CL4 Refrigeration Canopy Luminaire
Application
The high performance luminaire is designed for refrigerated environments where the normal operation ambient temperature is below 60°F. The low 1.75” luminaire profile minimizes the chance for luminaire damage due to operational traffic. The luminaire’s sloped walls further help by forcing the contact object to slip under the luminaire.
Construction
Heavy duty single piece die cast aluminum housing for durability. The fixture is sealed to the elements and can be cleaned by pressurized water (IP65 rated)1. The power supply is remotely mounted outside of the refrigerated environment for heat reduction and maintenance ease. The LED lamps are mounted onto dedicated heat sinks. The “starburst” heat sink conducts heat from lamp to radial fins and onward to the cooled pyramid walls.
Finish
A super durable polyester powder coat finish is electrostatically applied. Standard housing finish is white. Custom colors available upon request.
Optical System
Two optical options are available. Option 1 – utilitarian design for maximum efficiency having downlight option only for mounting heights between 18’-22’. Option 2 – reduced glare diffuse hemisphere lens for general purpose lighting with all glare virtually eliminated for an aestetically appealing and even distribution of light. Also, each luminaires’ lamp optical assembly is independent of neighboring lamps permitting the use of multiple optics on a single luminaire.
Electrical System
The constant voltage LED power supply operates off a voltage input range from 90V~305V (50/60 Hz). An internal surge protection device protects the assembly from up to 10,000 kV surge events. For ease of service the power supply is typically located outside the refrigerated box with a max remote distance of 100’.Through an integral J-Box located at the luminaire center, power and signal are distributed to lamps and when needed, to nearby luminaires. 80 CRI LED lamps are available in a 4000°K color temperature. An occupancy sensor can be used as the J-Box cover.
Mounting
A patent-pending invention sets the luminaire apart. A single non-conductive through bolt secures the luminaire to the ceiling panel. Inserted from above through a ⅞” dia. bore, the bolt also acts as a wire conduit. The bolt luminaire entry is at the J-Box. The luminaire installation is quick and easy, eliminating common issues such as sweating and air infiltration.
