LuxiGen™ Infrared Dual-Junction Emitters

LuxiGen™ Infrared Dual-Junction Emitters

LED Engin's LuxiGen infrared dual-junction emitter family consists of infrared 850 nm and 940 nm in single- and 4-die packages. The 4-die LZ4 parts are the world's most powerful IR emitters, delivering 6x the flux density of conventional emitters to extend the range and resolution of surveillance and security systems by this factor. Single-die types deliver 70% more output than typical single-junction IR emitters in the industry. In both product families each die has 2 serially-connected junctions, creating 2 radiant surfaces and boosting output. A continuous 5 A pulse-drive capability means that they can produce a short-output burst for even greater range. The emitters are designed for IR systems operating at up to 150 m.

Features
  • 4.5 W (LZ4) and 1.15 W (LZ1) flux output at 1 A drive current
  • Low-thermal resistance: 2.8 C/W (LZ4); 6.0 C/W (LZ1)
  • Compact-footprint: 7 mm x 7 mm (LZ4); 4.4 mm x 4.4 mm (LZ1)
