| 20120001204 | COLOR ADJUSTING ARRANGEMENT - Disclosed is a color adjusting arrangement comprising: i) a first wavelength converting material arranged to receive ambient light and capable of converting ambient light of a first wavelength range into light of a second wavelength range, and/or reflecting ambient light of said second wavelength range, said second wavelength range being part of the visible light spectrum; and ii) a complementary wavelength converting material arranged to receive ambient light and capable of converting part of said ambient light into light of a complementary wavelength range, which is complementary to said second wavelength range, and arranged to allow mixing of light of said second wavelength range and said complementary wavelength range; such that light of said second wavelength range that is emitted and/or reflected by said first wavelength converting material and light of said complementary wavelength range is mixed when leaving the color adjusting arrangement towards a viewing position, the light leaving the color adjusting arrangement thereby appearing less colored, i.e. having a color point substantially near the black body line. The invention thus allows an undesirable colored appearance of a semiconductor-phosphor based light source to be at least partly extinguished or neutralized. | 01-05-2012 |

| 20110062469 | MOLDED LENS INCORPORATING A WINDOW ELEMENT - A light emitter includes a light-emitting device (LED) die and an optical element over the LED die. The optical element includes a lens, a window element, and a bond at an interface disposed between the lens and the window element. The window element may be a wavelength converting element or an optically flat plate. The window element may be directly bonded or fused to the lens, or the window element may be bonded by one or more intermediate bonding layers to the lens. The bond between the window element and the lens may have a refractive index similar to that of the window element, the lens, or both. | 03-17-2011 |
