Lightfair International 2008: Field Report

Jul 1, 2008 12:00 PM, By Joe Knisley, Senior Editorial Consultant

Fixtures

Fixtures continue to evolve in response to market needs. Hubbell's DualLight PG series of wall packs uses the LED source for outdoor emergency lighting along egress paths and perimeter walkways. For shallow and cluttered plenums, Cooper's Corelite Class R Ultra Shallow Recessed series requires half the space of traditional lay-ins; Lightolier has similar models.

Part of Lithonia Lighting's Relight solution for retrofitting existing lighting systems, the RT 5 Relight offers the same features of its RT 5 volumetric lighting fixture, without replacing the entire fixture. The ES 8 is a similar solution for T8 lamps.

TCP, Inc., introduced its specification fixture division, EcoVations, which includes a line of T5 and T8 fluorescent lensed and open bottom fixtures for commercial and industrial applications.

Cooper Lighting's line of Iris recessed fixtures features a two-stage optical system, and the lamp type and trim can be changed out and reconfigured from below the ceiling during construction or later.

Looking to the future

During the show, a group of companies announced they had formed the EnOcean Alliance, which seeks to establish technology developed by EnOcean as an international standard for wireless controls in buildings. The ongoing development of interoperable, self-powered, wireless monitoring and control products (for lighting and HVAC systems, as well as other functions) in residential, commercial, and industrial buildings lowers both installation and ongoing energy costs. These battery-less sensors and switches are powered by slight changes in ambient conditions such as temperature and humidity, by ambient sunlight, or by manual operation of a rocker switch. An RF transmitter can be used to communicate with a variety of freely programmable WAGO controllers such as BACnet, LON, Ethernet, Profibus, and Modbus TCP, thus expanding building automation possibilities, such as sunshade control.

Founding promoters of the alliance include: Masco, Leviton, EnOcean Distech Controls, MK Electric (a Honeywell subsidiary), Omnio, and Thermkon. Texas Instruments, Siemens, and Osram Sylvania are just a few of the many participant-level members. A third classification, associate membership, includes building professionals, small distribution partners, and academics. Already, more than 70 manufacturers provide more than 300 products that operate in the 315-MHz band in the United States.
