Kilolumens LED Package Development (2000流明LED封裝)
- Single Chip HP (SCHP) LEDs
• Replacing Multiple LED Chip with Single Chip LED
– Multiple HB LEDs vs. Single COB Array LED
– COB Chip Array package vs. Single Chip LED
• Enlarge Optical Design Flexibility
– High optical efficiency from narrow to wide beam application
• LED Chip Size:
– 1mm2, 2mm2, 5mm2, 9mm2
– Bigger Chips …
• Saving Packaging Cost with bigger chip LED
– One Package vs. Multiple Packages

The Big Chip LED Value Proposition
•
1 mm
Replaces existing lighting technologies
 Specialty Lighting: Metal Halide, Mercury, Xenon
4 mm2
5 mm2
9 mm2
12 mm2
 General Lighting: Metal Halide, HPS, Halogen
•
Ideal Applications
 Specialty Lighting: Etendue limited systems
 General Lighting: Directional / long throw fixtures requiring lots of lumens
•
Single LED solutions (instead of LED arrays)
 Big chip + high lumen density + high efficiency equals:
• Enough optical “punch” for the application
• Less complexity and cost than LED arrays (optical & operational simplicity)
High lumen applications requiring precise optical control

Optical considerations for SCHP LEDs
Single big chip vs. array of small chips
•Single monolithic chip
•Conformal phosphor coating maximizes lumens/emitting area
1,000
lumens
•Array of small chips (spatially separated)
•Phosphor/encapsulant slurry with large emitting area
θ

Maximizing lumens/mm2 enables smaller fixtures and
better beam control – simpler and less expensive optics!
13
Optical considerations for SCHP LEDs
Center beam candle power (CBCP)
4-chip LED array
Single big chip
Delivered beam pattern patters
Narrow beam optics tend
to reimage the source
Chip array beam
Single source beam
Single big chip enables higher Center Beam Candle Power &
more uniform beam pattern for narrow beam spot lighting
14
SCHP LED Recent Development
• Chip Size is getting bigger
– 9mm2, 14mm2 & 18mm2
– Bigger Chip ?
• Multiple Color
– RGBW, RGBA
– RGBIR & RGBUV
• Chip Shape
– Square, Rectangular (4:3; 16:9)
– Round
• Build-in Functionality
– Chip protection: ESD, TVC
– Tj monitor

SCHP Application Challenges
• High LED Driving Current (If)
– Requests high current handling capability Driver
• Power module, Ballast
• Driver IC delivers up to 30A and application circuit is avaliable
• Thermal Management (Tj)
– High power LED creates high thermal request thermal design
• Junction Temperature (Tj) monitor and control;
• Thermal Resistance reduce down to 0.6C/W
• Reliability
– Meets L80 requirement
