– Heat dissipation capability neede

– Heat dissipation capability needed– Electrical power supply 115 VAC / 400 Hz / power up to 270W– Max weight 8-10kgs for each – Size of surface to illuminate : ~18m²– Light power expected in output ~3000 lumens (expected surfacic luminance is around 150 lux on the tail)– Monochromatic version in a first step– Image definition: full HD (could be less), 50 image / s. Contrast is to be defined but is expectations are not very stringent.– Technology considered is DLP with LED light source (LCD robustness in temperature cycles is identified as a blocking point, as well as laser performance in a wide range of temperature)– Data stored locally on the projector: SD card as first step / flash memory (better wifi connection)
