LED Engin, Inc. announces the LZ4 flat lens family of compact, 4-die RGBW emitters for wash lamps and follow spots used in stage lighting
applications. Two variants are available: LZ4 that can be driven to 1A
and LZ4-Plus that can be driven to 1.5A per die, producing up to 550 and
725 lumens output respectively, some 30% more than rival products. The
multi-color LED die, which are mounted onto LED Engin’s propriety, multi-later thermally efficient substrate, are capped with a flat glass primary lens.
Precise color control is achieved via the ability to
individually address each die, in conjunction with in-source color
mixing and without the added complexity and cost of attaching color
filters to lamps. The compact LZ4 emitters with flat glass windows
can be used with various secondary optics, including zoom lenses and
imaging optics, and are capable of delivering beam widths down to 6
degrees in such systems.
This latest emitter technology facilitates the design of more
reliable, controllable and versatile studio lighting compared with high
intensity discharge (HID) lamps, often in much smaller enclosures. The
LEDs also deliver more consistent color over their service life, run
much cooler and save energy.
The technology underpinning the new emitters is LED Engin's LuxiGen platform.
LED die are fixed to a low thermal resistance substrate using a unique
gold-tin eutectic die-attach process. This allows users to drive the LED dies with higher current
and generate more light, while keeping junction temperatures low to
ensure long operating life. In the LZ4 RGBW emitters, four die of the
same dimensions are closely packed together onto each substrate for
optimized étendue. This produces narrower, punchy beams with better
color mixing and sharp cut-offs. Utilizing a flat glass lens allows the
primary optic to be closer to the die for highest coupling efficiencies
and facilitating the use of zoom optics, mixing rods, light pipes and
other TIR optics. The product also has its anodes and cathodes aligned,
simplifying board design when using multiple emitters in a single lighting fixture.
