20090147513 | BACKLIGHTING LED POWER DEVICES - A generally planar illumination, display, or backlighting device is disclosed, including a generally planar arrangement of side emitting light emitting diode (LED) devices generating side emitted illumination, and a generally planar arrangement of wavelength conversion elements arranged coplanar with the generally planar arrangement of side emitting light emitting diode (LED) devices. The wavelength conversion elements are interspersed amongst the side emitting LED devices and configured to wavelength convert the side emitted illumination generated by the side emitting LED devices. A display device using such a generally planar illumination device is also disclosed, in which a liquid crystal display (LCD) panel is backlit by the generally planar illumination device. | 06-11-2009 |
20100096974 | BLUE-GREEN AND GREEN PHOSPHORS FOR LIGHTING APPLICATIONS - Embodiments of the present techniques provide a related family of phosphors that may be used in lighting systems to generate blue or blue-green light. The phosphors include systems having a general formula of: ((Sr | 04-22-2010 |
20100177513 | HYBRID ILLUMINATION SYSTEM WITH IMPROVED COLOR QUALITY - A white light hybrid illumination system including an amber LED, a red LED, and a phosphor converted LED such as a blue LED chip and a green phosphor, wherein a peak emission difference between the amber and red LED is at least 25 nm. This system provides higher color quality than prior devices due to its high luminous efficacy, high CRI over a wide CCT range, and better color control. | 07-15-2010 |
