In the right figure the current optical set-up is shown. The Lamp reflector is designed
to reflect the light beam in parallel towards the optical unit. With the new Virtual
Light Sources technology the reflector is elliptical and in combination with a
concave lens a smaller light beam is obtained.
In addition the required distance between the light source and the LCD Panel
becomes shorter with the virtual light system.

7.2.2. New 165W Lamp (LMP-C150)

Since the Virtual Light source concept
requires a high accuricy of the assembly for

and the integrated concave lens.

High Mode (165W) and 2500 hours in Low
