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.

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.

Why Laser?


Laser/Phosphor: Advantages & Disadvantages• Advantages

• 20,000 Hours of Operation • No costly lamp replacements every 2,000 – 3,000 hours• Mercury free• Virtually Maintenance free

• Labor costs• Less cleaning of filters or filter free• Lower Internal Heat

• Redundancy (Consistent light output)• Dynamic self adjustment of Light module

• Disadvantages• Cabinet size


Advantage of Laser ProjectorLamp 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 CustomerLaser 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..

Light Source Adjustment: Benefits• Power Adjustment

• Variable Light source adjustment from 20%-100%• Lowers Black levels• Increases Contrast Ratio

• Simulation• NOC• Depends on the environment

• Constant Brightness• Fixed light output

• Edge Blending• Rear Projection• Simulation• NOC


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

Original Source Color

Lamp after 2500-3000 hours of usage


Quick Start: Benefits• Quick Start

• No wait time for power up and shut down

• Almost instant confirmation that the projector is powered on

• Lower aging of the light source• All Verticals


• Tilt Free• 360°Vertical Rotation for projection at any angle

• Signage• Large corporations• Museum • Signage• Simulation• Theme Parks

• Portrait Mode• Proper Print Layout for Publishing
