STEVAL-ILL009V3 STMicroelectronics

STEVAL-ILL009V3 OSRAM OSTAR projection LED board Data Brief Features Outstanding brightness and luminance due to pure surface emission and low Rth prepared for additional optics Dominant wavelength: 617 nm amber (red) Dominant wavelength Color 2: 525 nm true green Dominant wavelength color 3: 464 nm blue Viewing angle at 50 % IV : 120 (lambertian STEVAL-ILL009V3 emitter) 2 Light emitting surface: (typ.) 2.1 x 2.1 mm Description Technology: InGaAlP thinfilm amber (red) Technology color 2: ThinGaN true green This board should be connected through the 30- pin connector to the STEVAL-ILL009V1 control Technology color 3: ThinGaN blue board to be able to show the light effect with the 2 Luminance: 18*106 cd/m amber (red) board. The OSTAR projection module, used as 2 Luminance color 2: 14*106 cd/m true green light source, has a maximum forward current of 2 700 mA. The NTC resistor is directly assembled Luminance color 3: 3.5*106 cd/m blue on the OSTAR module. As the power of the Efficacy color 2: 86.0 lm/W true green module is above 10 W, the heatsink is used to Efficacy color 3: 17.0 lm/W blue keep the temperature in range. The biggest advantage of the OSTAR module is that red, ESD-withstand voltage: up to 2 kV acc. to green and blue LEDs are in the same package, JESD22-A114-B very closely assembled and therefore the color effect is better than with three separate LEDs.
