Edfu Temple

Egyptian technology company Horizon for Trading & Contracting used four Christie Roadster S+20K 3-chip DLP® projectors to stage their most ambitious integrated show to date, at the Temple of Horus in Edfu. This was the first time that large format projection has been used in any of Horizon’s shows.

LED Illumination

LED illumination providing long life, reliability and virtually maintenance-free visual displays.

Light-Emitting Diodes (LEDs) have emerged as a solid-state replacement for traditional high-intensity discharge (HID) lamps. LEDs provide a number of distinct operational and performance advantages that solve many of the challenges in projection arrays. This unique, solid-state lighting technology is ideal for display and illumination applications that require high brightness and the efficient harnessing of light from a small point source.

The application of LED illumination to visual displays, in particular, arrayed displays such as control room video walls or simulation and training environments, brings a host of unique and challenging requirements that are simply not addressed by consumer or light commercial-use projection displays. These requirements require purpose-built solutions. 

LED offers several benefits, including:

  • Solid-state illumination technology
    LEDs are solid state with no moving parts. There is no lamp arc to ignite, degrade and maintain over time

  • Instant on
    Unlike arc lamps, which may take over a minute to turn on and reach full brightness, LEDs turn on instantly

  • Extremely long life
    The rated lifetime of the LEDs is 60,000 hours (almost seven years) 

  • No colour wheel required
    The high-speed on/off capability of LEDs means that for 1-chip DLP systems there is no need for a motorised colour wheel. Red, green and blue LEDs can be sequenced at rates many times higher than colour wheels, reducing the likelihood of visible sequencing artifacts

  • Wider colour gamut for more vivid colour
    The colour spectral characteristics and range surpass that provided by traditional colour wheel-based systems. LEDs far exceed European Broadcasting Standards minimums and the system allows colour performance to be easily manipulated to best match the application

  • Better brightness control
    LEDs offer a wide range of brightness control, unlike mercury lamps which offer only about 10-25 percent brightness adjustment. In addition, there's no need for mechanical apertures to adjust brightness

  • Environmentally responsible
    LEDs are an environmentally responsible "green" light source, free of hazardous substances found in conventional lamp technologies

Christie's LED Illuminated solutions

Christie has a proven track record designing and manufacturing purpose-built products tuned to the needs of specific markets, and a history of innovations that provide solutions for the unique challenges of projection arrays. The Christie Matrix StIM™ projection system with InfraScene™ LED technology for night-vision goggle simulation and the Christie Entero™, both feature Christie ArrayLOC™ for intelligent self-adjustment of the array in real time is simply the latest. Christie ArrayLOC™ successfully exploits the advantages inherent in LED technology to provide a scalable-environment, seamless display system that is highly reliable and virtually maintenance-free. This technology revolutionises the training experience.

Christie MicroTiles™ take display technology to a new frontier. Built on proven DLP® technology and specifically designed for maximum image quality in high-ambient light environments, Christie MicroTiles are ideal for a wide range of demanding applications, including architectural elements, out-of-home advertising, command and control video walls, and event production.

Using the strengths of both rear projection and LED technology, Christie MicroTiles offer substantially brighter images and a much wider colour palette than conventional LCD and plasma displays. With no practical limit to the number of tiles in a display, Christie MicroTiles produce a virtually seamless canvas with an unlimited number of super-fine pixels.

Long life, reliability, virtually maintenance-free visual displays

LED illumination revolutionises visual displays by offering a platform that contains no consumable components, which would otherwise require scheduled replacement and maintenance.  With seven to ten years of operating life (depending on the application) and built-in management features that continuously monitor and manage brightness, colour control and black levels across the entire display. Christie's LED-illumination technology platform ensures virtually zero-maintenance operation.
