Solid-state light emitting devices including light emitting diodes in package structures
Last updated:
Abstract:
Solid-state light emitting devices including light-emitting diodes (LEDs), and more particularly packaged LEDs are disclosed. LED packages are disclosed that include an LED chip with multiple discrete active layer portions mounted on a submount. The LED packages may further include wavelength conversion elements and light-altering materials. The multiple discrete active layer portions may be electrically connected in series, parallel, or in individually addressable arrangements. The LED chip with the multiple discrete active layer portions may provide the LED package with improved brightness, improved alignment, simplified manufacturing, and reduced costs.
