Abstract:
1. A variable-color light-emitting structure, comprising: a ground path connected to a ground voltage; a first current path configured to receive and pass a first control current; a first light-emitting element connected to the first current path, configured to receive the first control current from the first current path, configured to generate light within a first wavelength range based on the received first control current, and configured to pass the first control current; a first conductive substrate portion formed over the first light-emitting element, and electrically connected to the first light-emitting element, the first conductive substrate being configured to receive and pass the first control current from the first light-emitting element; a first connection element, having a first upper contact and a first lower contact, the first connection element being configured to receive the first control current from the first conductive substrate, and to pass the first control current from the first upper contact to the first lower contact; a second current path configured to receive and pass the first control current from the first connection element; a second light-emitting element being electrically connected to the second current path, being configured to receive the first control current from the second current path, being configured to generate light within the first wavelength range based on the received first control current, and configured to pass the first control current; a second conductive substrate portion formed over the second light-emitting element, and electrically connected to the second light-emitting element, the second conductive substrate being configured to receive and pass the first control current; and a grounding element electrically connected between the second conductive substrate portion and the ground path, the grounding element being configured to receive the first control current from the second substrate portion, and to pass the first control current to the ground path.
