A per LED) • National, Linear Tech, Zetex Cypress Confidential

Design challenges with HB LEDs SR Micro SR SR Temp/Color Sensor 5 LED Shortcomings Customer Challenge Customer Need Binning: LEDs are spec’d by chromaticity, brightness, and power Difficult to achieve repeatable color point Flexibility at production time Temp Variation: LEDs degrade over temp, different color LEDs degrade at different rates Difficult to maintain color point over time Color control during production Cypress Confidential

HB LED Challenges: Binning The same color LED varies in output and is classified by bins LED Bin “J” Bin “K” Bin “L” Red Green Blue • Inaccurate Color Mixing • No production consistency for end systems 6 Cypress Confidential

HB LED Challenges: Temperature effects • Light output decreases • Wavelength increases • Forward voltage decreases LEDs degrade at different rates Added complexity in controlling a color mixed output over time 7 Cypress Confidential

How it could be done Firmware, firmware • Map out possible permutations & incorporate into code – very inefficient – OR – Use specific bin for a LED • 10 -15% premium for mandating specific HB LED bins IF available 8 Cypress Confidential

HB LED design with ZERO Code • PSo. C Express 3. 0 – Visual Embedded Design Tool • Powerful new tool for lighting applications • Create single or multiple color channel designs in minutes with ZERO “C” necessary • LED-specific Express drivers for EZ-Color 9 Cypress Confidential

Appendix 21 Cypress Confidential

Color Mixing Basics • Mixing Red, Green, and Blue generates a color • Red + Green = Yellow • Blue + Red = Magenta • CIE chart developed to provide science behind color • Color space defined with (x, y, Y) coordinates • x and y define chromaticity (color) • Y define luminance (brightness) 22 Cypress Confidential

Color Mixing Basics • HB LEDs defined in (x, y) coordinates Red: (. 68, . 29) Green: (. 23, . 63) Blue: (. 15, . 06) • These HB LEDs form a color gamut • Output any color within the triangle 23 Cypress Confidential
