What is laser phosphor illumination?

A solid-state, lampless projection illumination technology
Uses blue laser diodes as the primary light source.

Why laser phosphor?

Conventional illumination means expensive lamp replacement on-going maintenance costs and images that degrade – and the brighter the lamp, the shorter the life. For an installation projector, that’s 2,000 hours. Laser Phosphor illumination lasts 20,000 hours, ten times as long.

Types of laser phosphor illuminated projectors

Typical laser phosphor
Employs blue laser diodes shining onto a phosphor wheel.

Laser phosphor hybrid
Same as a typical laser phosphor projector but adds a red LED light source to boost the red colour component.

Laser phosphor with red laser
Similar to a laser hybrid, but employs a red laser diode instead of an LED to produce better overall saturation and realistic colours. Forms the basisfor Christie® BoldColor Technology.

Typical laser phosphor illumination system

To generate the three primary colours in a 1DLP® laser phosphor projector, the laser diode shines laser light onto a phosphor wheel to create yellow and green light, while blue laser light passes through an opening in the phosphor wheel. The projector then sends the yellow and green light through a colour wheel to generate red and green, while the blue laser light passes through a diffusion window.

These red, green, yellow and blue colours are then directed onto an imaging surface, such as a DLP chip which directs the light through a lens and onto the projection screen.
