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

• Replaces existing lighting technologies

Specialty Lighting: Metal Halide, Mercury, Xenon

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)

Optical considerations for SCHP LEDs Single big chip vs. array of small chips

•Single monolithic chip

•Conformal phosphor coating maximizes lumens/emitting area

θ

θ

•Array of small chips (spatially separated)

•Phosphor/encapsulant slurry with large emitting area

Maximizing lumens/mm2 enables smaller fixtures and better beam control – simpler and less expensive optics!

Optical considerations for SCHP LEDs Center beam candle power (CBCP)

Delivered beam pattern patters

4-chip LED array Single big chip

Single source beam Chip array beam

Single big chip enables higher Center Beam Candle Power & more uniform beam pattern for narrow beam spot lighting

Narrow beam optics tend to reimage the source

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



Luminus’ Big Chip LEDs are rapidly displacing traditional lighting technologies
