Developed in conjunction with an engineering team from a leading LED manufacturer, the 19000 Series is designed to help LED engineers meet both space constraints and operating parameters. With a low-cost, lightweight aluminum profile, the 19000 series offers maximum thermal performance that makes matching the right heat sink to the right LED a much less time-consuming process.
The 19000 heat sinks are designed to make maximum use of available resources. In addition to being black anodized for maximum thermal performance, they are also constructed with a radial- fin geometry that has been optimized for natural convection.
These design benefits are ideal for many types of LED lighting fixtures. Though 19000 Series heat sinks are most commonly used in both recessed and externally mounted down lighting applications, they are equipped with extrusion profiles that suit a variety of LED configurations. Mounting features are in fact incorporated as part of the extrusion, so that the 19000 series can be easily mounted with standard hardware. Each extrusion profile has screw bosses located precisely to enable easy LED substrate attachment, and provisions for slip-nut attachment make it easy to assemble the 19000 series heat sinks into diverse lighting fixtures.
Wakefield offers five different models of the 19000 series, each designed for a different maximum power rating and expected temperature rise above ambient temperature. Options range from a maximum 14.7° C rise for a 4.5 watt power rating to a maximum 29.2° C rise for a 42.8 watt power rating. All models do not exceed a maximum LED substrate temperature of 75° C, and are available in multiple sizes, weights, and thermal resistances.
Heatsink lengths range from 2 inches (50.8 millimeters) to 10 inches (190.5 millimeters), with diameters of 1.26 inches (32 millimeters) to 4.51 inches (115 millimeters), while the heat sink weights range from 0.2 pounds (92 grams) to 2.64 pounds (1199 grams). Available powers include 42.8, 26.3, 9, 4.5, and 24 watts, with corresponding thermal resistances of 0.68, 1.15, 2.38, 3.27, and 1.15 C/W.
