This week’s Lightfair International event in Las Vegas, NV, USA sees the North American debut of new, highly efficient solid-state lighting solutions for the general lighting market from Philips of The Netherlands that use Luxeon Rebel power LEDs made by Philips Lumileds of San Jose, CA, USA.

Both the Fortimo and Lexel downlight modules (DLMs), with accompanying thermal and power systems, enable lighting OEMs to quickly and easily equip the architectural and specification communities with complete white and tunable downlight solutions, the firm says. Fortimo modules can potentially reduce energy consumption by as much as 50% compared to compact fluorescent lamp (CFL), and Lexel modules can deliver perfectly controllable illumination, it is claimed.

The Fortimo DLM 1100 uses 18 royal-blue Luxeon Rebel LEDs and a remote phosphor lens at the top of a mixing chamber to create a white-light module delivering 1100 lumens of light output with an efficiency of 62lm/W. A second version of the Fortimo module delivers 2000lm at 45lm/W. Initially introduced with a 4000K correlated color temperature (CCT), the use of different remote phosphor lenses allows for the possibility of additional white CCT options in the future.

By using royal-blue Luxeon Rebel LEDs, Fortimo maximizes the photonic energy directed at the remote phosphor lens. Careful matching of the wavelength of the LEDs to the characteristics of the phosphor in turn maximizes the light output and efficacy of the module. The small 44mm x 82mm x 83mm Fortimo footprint allows the modules to be integrated with a wide variety of reflector solutions used in downlights.

Luxeon Rebel also lights the tunable white Lexel DLM-1000 module. Also designed for downlight luminaries, the Lexel DLM delivers 1000lm of light and has a tunable white-point between 2700-6500K with excellent consistency and a color rendering index (CRI) of at least 80.

Both the Fortimo and Lexel downlight modules are made possible by the small size and high flux of Luxeon Rebel LEDs, Lumileds claims. The Fortimo DLMs also use the ability of the Luxeon Rebel to be driven at currents of 350-1000mA, so that usable light can be maximized and system design simplified.
