Luminus expands PhlatLight LED product line for microdisplays

Luminus Devices Inc of Billerica, MA, USA has launched the PhlatLight PT54 chipset, optimized for maximum efficiency in microdisplays of 0.4-0.6” in size (including high-brightness pocket projectors and head-up projection displays) as well as other general illumination applications.

The photonic-lattice-based PhlatLight PT54’s three-color system includes separately packaged red, green and blue LEDs, each 5.4mm² in size and capable of sustaining high power under fast pulsing or continuous-mode operation. Combined, the chipset produces up to 1400 peak white lumens in pulsed mode. The chipset is suitable for 0.55” SVGA digital light processing (DLP), liquid crystal on silicon (LCoS) and high-temperature polysilicon (HTPS) LCD microdisplays with a 4:3 aspect ratio.

A single PT54 chipset emits ten times more brightness than conventional LEDs, claims the firm. Other benefits include ‘instant-on’ with full brightness (since there is no warm-up time, as for the mercury lamps found in traditional projection TVs), a wide color gamut, and digital power management to optimize battery life and brightness. With a median lifetime that exceeds 120,000 hours, PhlatLight LEDs also have significantly longer lifetimes than arc lamps, eliminating lamp replacements.

The PhlatLight PT39, Luminus’ most compact LED projection chipset, is the light source in LG Electronics’ recently introduced HS101 pocket projector (which is the brightest LED-based projector on the market, it is claimed). PhlatLight chipsets are also in projection TVs sold in North America by Samsung and NuVision, with screen sizes up to 61”.
