Reliability Information
Average monthly projection time: 44.0 hrs/month
2.00 hrs/day x 22 working days/month
Failure Rate
1st year: 0.0025 cases/unit/month
2nd year: 0.0029 cases/unit/month
3rd year: 0.0037 cases/unit/month
The failure rate of a projector increases with its
total power-up time. This is due in part to the
failure characteristics of optical engines in
projectors.
Lamp Life
Normal Mode: 3,000 hrs
Eco Mode: 4,000 hrs

Lamp Near-end/End Alerts
There is no near-end alert.
The lamp end alert occurs when the machine
calculates that the life time has expired.
If used in Normal Mode only, the alert appears
after 3,000 hrs projection time
If used in Eco Mode only, the alert appears after
4,000 hrs projection time
If the user switches between modes, the machine
calculates when to display the alert based on
how long the lamp was used in each mode.

Disposal of Broken Lamps
Projector lamps normally contain mercury
vapour.
These lamps can rupture due to impact or being
used longer than their life expectancy.
The time that the breakage will occur differs
widely for each lamp and its circumstances of
use.
These lamps must be disposed of in accordance
with local environmental regulations.

Optical Components
The DMD chip is the central part of this type of projector.
A DMD chip consists of many small pixel-sized mirrors laid out on a semi-
conductor chip. Light shone on the DMD chip is reflected by all these tiny
mirrors. (For a chip with 1024 x 768 resolution, there are 786,432 small
mirrors.)
Light is shone onto the chip through a fast-spinning color wheel (CW in
the diagram) that has a red sector, a green sector, and a blue sector.
This light is reflected off the chip and out through a lens onto a screen.
Lamp: Light source
UV-IR Filter: Lets visible light through (wavelengths between 380~780nm) and
prevents UV and IR damage to other optical parts.
CW (Color wheel): The wheel has a red segment, a green segment, and a blue
segment. The wheel rotates to provide red, green, and blue light (the color of the
output beam changes from red, to green to blue)
Integrating Rod: Gives the light a uniform luminous flux.
L3: Condensing lens. Condenses divergent light.
L2: Condensing lens. Works with L3 to condense divergent light.
M1: Mirror 1. Changes the light direction.
M2: Mirror 2. Changes the light direction.
Relay L1: Condenses and magnifies divergent light before it goes to the DMD.
DMD Chip: Contains micro mirrors to generate the image
Projection Lens (WT41 in the diagram): Projects the image onto the screen.

15
Antares-PJ1Training
Slide 15
DMD Chip
R, G, and B signals from the image generating device are sent to
the DMD chip, and timed so that the red signal arrives at the same
time that the red part of the wheel is in the beam path, and
similarly for the green and blue signals.
The DMD chip generates the R, G, and B images by re-positioning
the micromirrors using micromachined hinges to make different
pixelated images for each colour (meaning that each micromirror
has an ON and an OFF position).
For SVGA resolution, the mirrors are 16-micrometer squares, with
a gap of about 0.8 micrometers between each mirror.
