Summary of Philips’ novel LED/phosphor combination hits 200 lm/W in warm(ish) white
The article describes the TLED prototype, a 7.5W lighting device achieving 1,500 lumens at 200 lumens per watt efficiency. It utilizes a novel combination of separate red, green, and blue LEDs manufactured by Lumileds. The blue and red LEDs function as direct emitters using InGaN and AlInGaP materials respectively, while the green component is highlighted as particularly interesting within this specific Philips innovation.
Parts used in the TLED Prototype:
- Red LED
- Green LED
- Blue LED
- Lumileds manufacturing components
Inside the 7.5W 1,500 lm (200 lm/W) prototype, called TLED, there are separate red green and blue LEDs, and the green is particularly interesting. All made by Lumileds, a Philips spokes woman told Electronics Weekly, the blue (InGaN) and red (likely to be AlInGaP) are direct emitters.
