SORAA POINT SOURCE OPTICS
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
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
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

SORAA FLICKER FREE TECHNOLOGY
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 (100-120Hz) 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
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
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
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
When it comes to qua lity of light SO RAA outshines the competition.
