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.

LEDengine-V
Standard operating current and light output in the chart are based on the datasheets of the Sharp LEDs inside, as is the
maximum LED temperature. 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.

Mounting
LEDengine-V is mounted behind a plate using four No.4 x ¼” self-tapping screws which pass from the front through
clearance holes in the plate and bite into the holes on the LEDisk at the front of the LEDengine. 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).
