• Task: Design of a compact reflector optics for three LED sources with different emission characteristics (80°, 120°, 150°). Result: Three reflectors with comparable diameter.
• However: Considerable efficiency differences between 150°and 120°optic LEDs.

Color Rendering and Luminaire Efficacy
With standard white LEDs it is not possible to realize luminaires or LED lamps with both high efficacies and a high CRI.
With the Brilliant Mix Concept a high CRI and high efficacies can be realized!
Note: Luminaire efficacy
includes thermal, optical
and electrical losses!

• High color rendering index: Ra ~ 90
• Very high LED efficacies of > 110 lm/Wpossible (~25 % higher than phosphor converted warmwhite with comparable CRI)
• Optical mixing of EQ White & amber LED
• More complicated logistics
• Control of LEDs to realize the stability of the CCT (over lifetime and temperature)
• Calibration of the CCT during manufacturing

• Integrated silicon lens features long lifetime (t >30,000 h) & high efficiency (η = 90 %) compared to low-cost thermoplastic lenses (t ~ 1,000 h; η = 80 %)
• No lens mounting process
• Excellent second board reliability
Essential product features
For high-quality street lighting luminaires with long life times the GD oval plus can be highly recommended!

Golden DRAGON Oval PlusCalculation Example
• Luminous Flux of the component: 97 lm
• No further optics required. No losses: - 0 %
• Total luminous flux: 97 lm
Golden Dragon Oval plus
A GD oval plus whose luminous flux is ~16 % lower than other LEDs may yield an application efficacy which is approximately 5 % higher.
• Luminous flux of the component: 115 lm
• Aperture losses: Light that is radiated under large angles won't reach lens: - 5 %
• Losses of the lens (Fresnel reflection at
interface air / PMMA & internal losses): - 15 %
• Total luminous flux: 93 lm
Competitor LED without integrated optics
In this example a Golden Dragon oval plus LED will yield an application efficacy which is approximately 5 % higher compared to the competitor LED.
