Abstract
Solid state light emitting devices including light-emitting diodes (LEDs), and more particularly packaged LEDs are disclosed. In some embodiments, an LED package includes electrical connections that are configured to reduce corrosion of metals within the LED package; or decrease the overall forward voltage of the LED package; or provide an electrical path for serially-connected electrostatic discharge (ESD) chips. In some embodiments, an LED package includes at least two LED chips and a material between the two LED chips that promotes homogeneity of composite emissions from the two LED chips. In this manner, LED packages according to the present disclosure may be beneficial for various applications, including those where a high luminous intensity is desired in a variety of environmental conditions. Such applications include automotive lighting, aerospace lighting, and general illumination.
