Instructions for use

w For lamp re placement: switch off power, disconnect mains supply, disconnect power

cord, allow lamp to rea ch room te mperature.

with prolonged exposure.

w This VIP lamp must be operated only in suitably designed, enclosed fixtures which

prevent direct observation of the arc a nd will prevent lamp fragments from exiting, in the unlikely event of a lamp rupture.

w The burning position is 0° to +20° (0° optical axis horizontal). w Do not touch the lamp with bare hands. w If necessary, lamp can be cleaned with lint free towel before operation. w The lamp must be operated with the OSRAM lamp driver PT VIP 120 AC/100-240 H. w Protect lamp environment against high ignition pulse s (max. 23 kV). w Avoid direct contact of objects to reflector cover glass. w Fast on-off-cycles will reduce lamp life. w Use appropriate spa nner when assembling central connection. w Visible arc instability ha s to be suppressed by optical system. w Operate lamp only in accorda nce to UL 1950 regulations. w This lamp must not be operated with a broken, cracked or loose reflector or cover glass.

Disposal: For disposal of spent lamps, always consult federal, state, local and provincial

hazardous waste disposal rules and regulations to ensure proper disposal.

Caution: This lamp emits ultra violet (UV) radiation a nd operates at high pre ssure. This lamp

may only be used in enclosed fixtures that comply with UL1572. Due to the high luminous effica cy, the UV ra di ation which the lamp emits a nd the high pre ssure within the lamp, P-VIP â lamps may only be operated within enclosed, purpose-built housings.

Note 1 : Tilt Angle Tolerances

Limits on vari ability of mirror tilt half a ngle are critical in the design of the a ccompanying optical system. Variations in tilt angle within a device may result in apparent nonuniformities, such a s line pairing and image mottling, across the projected i mage. Variations in the average tilt a ngle between devices may result in colorimetry a nd syste m contrast variations. The specified limits represent the tolerances of the tilt angles within a device.

Note 2 : Active Area Reflectivity

The DMD specular reflectivity is defined a s the ratio of the light incident upon the mirror array to the light specularly reflected from it. The measure ment is made with all mirrors in the full on state without electronic duty cycle effects (i.e. mea sure using 100% duty cycle). The specified specular reflectivity applies to any arbitrary point on the DMD active area.

Note 3 : Window Transmittance

Double pass system .

Note 4 : Window Aperture

A shield is utilized on the interior peri meter of the window to improve system contrast and to expose only the active area of the DMD to the projection optics. Incident light of up to 40 degrees cone half angle shall be supported without interference (active area shading) from the window aperture. Light that falls outside the window clear aperture or outside the specified angle will have a detrimental effect on system optical and thermal performance.

Note 5 : Thermal Performance

The DMD is designed to conduct residual heat energy to the ba ck of the package where it ca n be removed by an appropriate heat sink. A device configured for a particular application can be ma nufa ctured with a thermal stud de signated f or that a pplication. The heat sink and cooling system must be capable of maintaining the package within the specified operational temperatures. The total heat load is largely driven by the incident light a bsorbed by the active area although other significant contributions that should be considered include light energy absorbed by the window aperture a nd electrical input power. The portion of incident light absorbed by the active area is determined from the active area absorption coefficient. Optical systems should be designed so that no significant light energy falls outside the window clear aperture as additional thermal load on the case top can damage the device.

Note 6 : Thermal Performance

The DMD is designed to conduct residual heat energy to the ba ck of the pa ckage where it can be removed by an appropriate heat sink. A device configured for a particular application can be ma nufa ctured with a thermal stud de signated f or that a pplication. The heat sink and cooling system must be capa ble of maintaining the package within the specified operational temperatures. The total heat load is largely driven by the incident light a bsorbed by the active area although other significant contributions that should be considered include light energy absorbed by the window aperture a nd electrical input power. The portion of incident light absorbed by the active area is determined from the active area absorption coef ficient. The absorption by the window a perture is the light ne ither spectrally nor dif fusely reflected according to the window a perture reflectivity parameters. Optical systems should be de signed so that no significa nt light ener gy falls outside the window clear aperture as any significa nt additional thermal loa d on the case top ca n damage the device.

6-3 Screen Defects

The following are the defect limits f or this product. They include DMD defects and lens

defects where the latter are visible as point or area artifacts.

6-3.1 Image Size

The projector shall be set up in the standard operating position for all evaluations in this section. Nominal image size is 121.9 cm (48 inches) wide, a nd 91.4 cm (36 inche s) high. The picture setting of the SOD shall be set for a linear gray scale reproduction.

* Defect Types

There are two types of defects covered in this section, optical blemishes and DMD defects. DMD defects consist of individual mirrors which do not change state correctly and do not reproduce the appropriate gray scale.

* DMD Defects

This includes mirrors which are stuck on (bright pixel), stuck off (dark pixel), stuck at some arbitrary angle (gray pixel) or who change state when they are not supposed to (twinklers). Observe the screen under a variety of conditions. Enumerate all single defects.

* Optical Blemishes

These are defects of the lens system, including scratches and specks of dirt, which result in noticeableor mea surable fixed variations in light intensity on the screen other tha n the expected light intensity fall of f from the lens axis. Classify blemishes as e ither major or minor. Minor blemishes are those which are not rea dily noticeable on screen at a viewing distance equal to the standard setup distance of

2.895 meters.

SERVICE MANUAL 6 - 7

Page 83

EzPro735

6-3.2 DMD Defect Limits

*Unstable Pixels

There shall be no unstable pixels (twinklers).

*Dark Pixels

Using a blue screen, level 180 out of a maximum of 255, look f or pixels and blemishes darker than this background level. There shall be no more than 4 single dark pixels. No adjacent dark pixels are allowed.

* Bright Pixels

Using a gray screen where each primary color is set to 30 out of a maximum of 255, look for pixels and blemishes that are brighter tha n this background level. None are allowed.

* Optical Blemishes

Optical defects must not be large or small and concentrated to the extent that they are easily visible.

* Minor Blemishes

Using both black and full white screens, count the number of minor blemishes. There may not be more than 6 of these.

* Major Blemishes

There may not be any major blemishes which are easily visible at the standard setup dista nce.
