Light Source Nomenclature
• SSL (Solid State Light Source) – A light producing system
that doesn’t use lamp technology.
•Hybrid – Solid State Light Source combined with other elements to
create colors.
• LED/Laser/Phosphor
• Laser/Phosphor
•LED – Red, Green and Blue LEDs.
•RGB Laser –Red, Green and Blue lasers. The only true “Pure Laser”.
• Pure Laser – What some competitors are calling their system even though they use
laser/phosphor.

LDs
Color Wheel
• Light source has B-LD and Y-Phosphor
• Light source used for all colors
Same LDs is used in Y-ch and B-ch
• Optical path of Y-ch
Blue light from LDs illuminate the phosphor wheel
Blue light converts yellow or green light with phosphor
Yellow and green light go into the Color Wheel
then into the Optical Engine
• Optical path of B-ch
Blue light transmits through the clear glass of phosphor wheel
Blue light goes through the Color Wheel then into the
Optical Engine

• Light Source has B-LD and Y-Phosphor
• Light source is two types
Y-ch : B-LD, λ=448nm
B-ch : B-LD, λ=462nm
We have to use B-LD with 462nm
in order to satisfy DCI Color Standard
• High Efficiency and Reliability
We use Diffuser and Light Tunnel in Y-ch
to create a uniform illuminance distribution in Y-Phosphor.

Advantage of Laser Projector
Lamp ProjectorLaser Projector
Light Source Unit has been constructed using multiple LD Bank.
Laser bank has two potential types of failures (1 component failure)
- Short mode
- Open mode
1 component failure
-> No Image (Black Out)
Laser Bank
(1 Bank)
Provide stable projection image to the Customer
Laser Projector has much lower potential for going to be black-out depend on the Light source failure.
Note1) Basically, Short mode would be expected failure. Open mode failure would be
very rare.

• Lowers Black levels
• Increases Contrast Ratio
• Simulation
• NOC
• Depends on the environment
• Constant Brightness
• Fixed light output

Color Critical: Benefits
• Color Critical
• As lamps age not only does the brightness
decrease but so does color saturation
• Laser/Phosphor wont have this same effect in such
a short period of time
• Relieves side-by-side or edge blending concerns
• Large corporations
• Higher education
• Museum / House of Worship
• Signage
• Simulation
• Theme Parks
• Control room / Video Monitoring
• Cinema
