a light source is a light source is a...?
• in the fierce projection market you have several illumination technologies available
– UHP (Ultra High Performance)– Xenon– LED– Laser
• the UHP and Xenon lamps are by far the most popular
• the lamps differ quite a lot and you will find arguments for both lamps

UHP™ (Ultra High Performance)
• Mercury arc lamp
• Same principle as Metal Halide lamp, but uses gas for stable light excitation
• The arc gap is 1-1,3mm across (2,0 or more for Metal Halide) which yields greater efficiency (“point source”)
– a 100W UHP lamp is capable of delivering more brightness than a 250W MH lamp
• Advantages of a small arc gap increases as the imaging devices (DMD) become smaller

Xenon
• Xenon arc lamps
• Traditionally used in film projection
• Native Colour Temperature is close to the noon sunlight
• Chromacity closely approximates a heated Black Body radiator
• Perfect for use in Ultra violet radiation systems as well as near Infra Red due to the Xenon wavelength

UHP selling points
• Colour benefits– great and stable colours over time– dual lamp systems yields better brightness uniformity (if light engine is designed
properly)• Cost
– the UHP lamps are far cheaper than the Xenon lamps• Lamp Life
– the UHP lamps has generally a much longer life span than Xenon (up to 5000 hours, eco mode)
– Xenon lamps lose brightness faster than UHP• Environmentally
– a UHP lamps give you more brightness per W consumed compared to the Xenon lamps• Flexibility
– 24/7 and uptime; It is preferrable to have a system of 2x300W lamps than a single lamp system (hot swapping of single lamp!)
• (Low) Operational Hazards– the UHP lamps has low pressure and represents a smaller hazard to the user when
handling the lamps compared to the Xenon lamps

Xenon selling points
• Colour benefits– native colour spectrum close to Noon Sunlight, or
D65• High power!
– yields very bright projection systems• DC operation
– Better colour wheel control with DC compared to AC operation
• Instant OnOff– supports on/off (restrike) with minimal effect on
colour projection– less than 60 seconds warm up time
• Single lamp design advantages– no color balancing– easier lamp replacement– reduced optics for light coupling

UHP counter arguments for Xenon’s USP
• Colour benefits– Solved with optical filters! The UHP lamp has a decent colour spectrum, no
IR and no UV with proper designed optics• High power!
– UHP lamps increases in power and efficiency all the time! For mainenance cost and lamp hours a system of 2x or 4x UHP lamps is clearly preferrable. But to reach 20-30K Lumens you need Xenon!
• DC operation– Philips VIDI’s digital lamp driving solves the major challenge about colour
timing related to colour wheel spin cycle (see VIDI slide later)• Instant OnOff
– Who cares? Who really need to use the projector within 30-60 seconds after you turn it on – if you care about image quality?
• Single lamp design– You have single lamp UHP systems too... ;) – A good designed dual lamp system allows you to hot swap lamps and to
have better brightness and colour uniformity

UHP vs Xenon Colour Spectrum
• Xenon is much better ”out of the box”
• UHP with filters and a good optical design provides D65 brightness (noon sunlight) and stable colour performance over time!
Yellow: peak performance of UHP lamps Blue: Flat spectrum of solar lightRed: Solar-like spectrum of the Xenon lamp

Xenon hazards (an extract)
• Source: USHIO (lamp manufacturer)
• Xenon Arc Lamps could burst when not in operation causing serious injuries!• • Xenon Arc Lamps have a high internal pressure. Depending upon the lamp, the
internal pressure can exceed 10 ATM or 147 PSI, even when not in operation.
• .Always wear eye/face and body protection when handling Xenon arc lamps!
• Never bump, drop, apply excessive stress, or scratch the lamp. This could cause the lamp to burst!
• Xenon arc lamps should not be used beyond their rated service life. Operation beyond the rated service life will cause the lamp to burst.

Philips VIDI™
• A variation of UHP technology, with new lamp driving technology
• Lots of benefits due to improved control of the pulsing:
– Brilliant Pulse allows us to peak segments of the colour wheel
– Dark Pulse allows us to lower brightness to a 25% level results in gray scale improvement (up to 2 bits)
– Tuned Plateau allows us to set controlled brightness in all coloursegments to boost white or to boost red, etc
– Improved BrilliantColor™ performance over lamp life time
– Improved RealColor™ handling
