5 GaN on GaN THE FOUNDATION OF PERFECTION

6 PERFECT CRYSTALS Conventional crystals generate many defects on foreign substrates Epita xia l GaN Foreign Substra te Standard (Sapphire, SiC, Si) GaN on GaN results in crysta l structure with 1000x fewer defects Epita xia l GaN GaN Substrate SORAA GaN on GaN

7 SMALLER DIE SIZE GaN on GaN s perfect crystal structure emits 5x more light per unit area tha n conventiona l LEDs Standard Competitor Die GaN on GaN Die 1000 x 1000 µm Efficiency of SO RAA s Tri-LED technology means tha t LEDs ca n be sma ller, reducing costs a nd ena bling a single source solution

8 INNOVATIVE CHIP DESIGN 1000x few crystal dislocations enables SO RAA s innova tive tria ngula r LED design, whilst GaN substra te ena bles volumetric chips Photon Esca pe Tri-la tera l ( Tri-LED ) configura tion a llows more light to esca pe die Roughened surfa ce of LED chip further improves light extra ction with efficiency beyond the thin-film limit, a pproa ching 90%

10 LEDs and spectrum Wavelength (nm) We generate a white spectrum by combining - a pump LED (violet for us) - several phosphors 10

11 VIOLET-EMISSION 3-PHOSPHOR TECHNOLOGY Standard LEDs emit blue light with red a nd green phosphors 2 phosphor mix produces a Broken Spectrum 380 Wavelength (nm) 780 SORAA emits violet light with red, green a nd blue phosphors 3 phosphor mix produces a Full Spectrum 380 Wavelength (nm) 780

20 SORAA POINT SOURCE OPTICS

21 POINT SOURCE OPTICS Directiona l lighting requires well controlled beam a ngles from na rrow to flood; tight form factors; and sharp single shadows Folded Prism Optics SO RAA s innova tive folded optics ena ble crisp, focused beams

22 NARROW BEAMS SO RAA s prismatic optic is a breakthrough in footprint, offering extremely narrow beam distributions from a low-profile design 10 degree beams possible from a lens just 8mm thick (MR16 & GU10) Fundamental laws of optics dictate that large sources in small form factors result in wide beam a ngles d = D sin (θ/ 2 ) d θ D The sa me la ws tha t hinder beam design with la rge, multiple light sources become a n a sset with a sma ll single source

23 CRISP SHADOWS SO RAA s Point Source Optics provide crisp, single sha dows Multi-Source Competitor LED SORAA Single-Source LED Multiple sources create multiple shadows Single source provides a crisp, single shadow Multi-source LEDs project multiple sha dows with multiple colours yielding less attractive results

25 SORAA FLICKER FREE TECHNOLOGY

26 WHY DOES FLICKER OCCUR? Flicker is ca used by the ripple in AC current which leads to a ripple in light output Current Current Time Time AC Input to la mp (50-60Hz) Rippled DC Input to LED ( Hz) Unlike in ha logen la mps, LEDs powered by AC sources respond almost insta ntly to cha nges in current Ripple in the light output is undampened, leading to a greater perception of flicker in LEDs

27 INVISIBLE FLICKER Huma ns a re sensitive to invisible flicker, or stroboscopic effect, due to va ria tions in light output between 50Hz 500Hz Wand Test Sma rtphone Test Intervals of low light lead to gaps in the fan Photographs show bands of light and dark Stroboscopic effects have been associated with headaches, eye strain and fa tigue

28 ERADICATING INVISIBLE FLICKER SORAA developed a two-sta ge digita l driver to elimina te the problem of stroboscopic flicker in our low voltage MR16 la mps Competitor Single Sta ge La mp Current Capacitor Current Time Time Capacitor receives rippled input and delivers reduced ripple to LED SORAA Two-Stage Flicker Free La mp Current Smaller Current 2nd Stage Current Capacitor Driver Time Time Time Sma ller capacitor delivers greater ripple, but 2nd sta ge elimina tes it completely

29 SORAA FLICKER FREE SO RAA s Flicker Free low volta ge MR16 lamps completely address the a dverse physiologica l effects of invisible flicker Wand Test Sma rtphone Test Smooth, unvarying light output leads to no gaps (flicker free) Results in clear photographs with no banding Two-stage driver acts as a consta nt flow va lve, smoothing the current a nd delivering fla t DC power to the LED
