Sample design:\

projection lens focal length: 345mm
Collimator fresnel: 220m
allowance
collimator fresnel to lcd: 2 inches for air circulation
Bulb to base plate: 2 inches

Most likely length of the box: 14in(345mm)+8.7(220mm)+2+2
;approx 27 inches

This is for the straight thru design. No mirror is used and the projector is in horizontal position. To save spave. a mirror is added on top and the projector will be in vertical position. This saves space.




Pictures of completed projector and all parts mounted. A power supply for fans and lcd using pc power supply is intalled near the projection lens.

Fans are installed at the sides one blowing between lcd and collimator fresenl and the other sucking out the hot air inside the box located down below.
