Patent ID: 10508799

Abstract:
Apparatus and associated methods relate to a lighted tree formed from a tree trunk section retaining a battery holder, branches extending from the trunk section, a light source disposed to emit light from a branch and electrically connected to the trunk section, and a base, adapted to mechanically support the trunk section and electrically connect the battery holder to an energy source external to the trunk section. In an illustrative example, the light source may be an LED-illuminated optic fiber. In some embodiments, the energy source may be a photovoltaic collector or multifrequency energy harvester. In some designs, the battery holder may adaptively maintain electrical polarity independent of battery orientation. In various implementations, battery holders may be stacked or rotated to one another to configure parallel or series batteries. Various embodiments may advantageously retain batteries in rotationally interconnected tree sections for common charging, or single in-tube section for smaller trees.
