Page 1 of 5 Issue1 01/11/2012 LEDengine-V 50 Watt LEDengine-V Up to 5400 lumens Fig.1 LEDengines use Sharp MegaZeni LEDs Description The Lumotrix LEDengine is a compact high power LED light module with integrated miniature heat-sink, fan and control electronics. The light source of the LEDengine is a Lumotrix LEDisk which is available in a choice of color temperature and CRI with a nominal 50W power rating. LEDisk is available separately and has its own datasheet. LEDengine type V is designed with a modified (round) LEDisk for front mounting behind an aluminium panel, with the LED looking through a hole in the panel. It requires a 24VDC constant voltage supply. This makes it easy to connect several of these LEDengines in parallel across a single supply and mount them on a single panel with a hole for each LED. This makes a high-power LED array. A future version of LEDengine-V will have the possibility to be dimmed using a 0-10V signal. Contact Lumotrix for more details. There are two other types of LEDengine – type C requires a constant current supply, and type D has DALI compatible control electronics and can use a DALI 24VDC constant voltage supply. Features: · High Power LED light source with heat-sink, fan and control electronics. · Over-temperature shut down. · Standard power supply: 24VDC · Designed for arrays. · Uses world class Sharp LEDs. · Low profile flat surface to fit most reflectors. · User supplies own reflector.

The maximum ambient temperature is based on the expected temperature rise of the LED. For LEDengine-V the expected temperature rise over ambient is 48ºC (measured experimentally). The absolute maximum temperature allowed for the LED is 100ºC. This means that the maximum allowable ambient temperature (shown in the selection chart Fig.3) is 52ºC (i.e.100ºC - 48ºC). All the V type LEDengines incorporate 50W LEDisks, but lower power LEDisks could be used for special applications. In the event of the fan being stalled the LEDengine incorporates a thermistor and control electronics which will shut down the LED until the fault is removed and a reset is initiated by temporarily disconnecting the power. Power supplies LEDengine-V can be powered by a standard 24VDC supply because it generates its own fan voltage internally. Connections to LEDengines are via loose wires into poke-in connectors. The wiring of the LEDengine poke-in connectors is negative to the left hand side and positive to the right hand side, see Fig.2. Reverse connection will not destroy the LEDengine. Preferred wire size is 26 awg e.g. 7/0.16 (7 strands of 0.16mm diameter wire). The choice of power supply depends on the power requirement of the LEDengine or array. Lumotrix offers 75, 110, 160, 250 and 440 watt constant voltage power supplies, suitable for 1, 2, 3, 4 and 8 LEDengines.

Recommended plate thickness is 2mm because this makes the plastic of the LEDisk on the front of the LEDengine lie flush with the front surface, but thicknesses 1.2mm to 3 mm are fine (see Fig.5). Power distribution is aided by Lumotrix connector block CN5 which has one input and four outputs, all in parallel. Distribution is via pairs of wires poked-in to the connectors on the LEDengines and the connector block. Cable ties can be used to secure the loose wires to holes placed near the edge of the LEDengine-V control boards (see Fig.6).
