Abstract: LED packages are disclosed capable of emitting a range of colors including white light, while still emitting that can have a high color rendering index (CRI). The LED packages can have a simplified reflective cup arrangement and improved lead frame design. The LED packages according to the present invention comprise one or more LED WITH PHOSPHORs for high CRI lighting applications, along with multiple narrowband emitters (e.g. RGB LEDs), but do not have a dam or partition to segregate the LED WITH PHOSPHOR from the multiple emitters. This results in a LED package that is less complex and easier to manufacture, while still providing the desired flexibility in LED package emissions.

Abstract: The present invention is directed to leadless LED packages and LED displays utilizing white ceramic casings and thin/low profile packages with improved color mixing and structural integrity. In some embodiments, the improved color mixing is provided, in part, by the white ceramic package casing, which can help reflect light emitted from each LED in many directions away from the device. The non-linear arrangement of the LEDs can also contribute to improved color-mixing. The improved structural integrity can be provided by various features in the bond pads that cooperate with the casing for a stronger package structure. Moreover, in some embodiments the thinness/low profile of each package is attributed to its leadless structure, with the bond pads and electrodes electrically connected via through-holes.

Abstract: This invention relates to a surface mountable light emitting device in which the lead frame is exposed over a substantial portion of the underside of the device so as to allow greater thermal conductivity to any device on which it may be mounted. The LED provides the lens and a molded body to encapsulate the lead frame and an electrical contact in a single molding step while the lead frames and further contacts are arranged in a suitable array. The lens couples the luminous output of a light-emitting diode (LED) to a predominantly spherical pattern comprises a transfer section that receives the LED's light within it and an ejector atop it that receives light from the transfer section and spreads it spherically. Applications may include, but are not limited to, household light bulbs and car headlights.
