  • Patent number: 10184654
    Abstract: A lighted decorative sculpture. The sculpture is wrapped in light strings having translucent electrical insulation that clads electrical conductors of the light string, so that some of the light emitted by the lighting elements propagates axially along the light string before being scattered, refracted, or reflected radially away from the light string. In this way, the light strings so arranged effectively function as their own reflector, eliminating the need for wrapping the sculpture in an outer layer prior to mounting the light strings. The ability to view between the wrapped light strings and into the illuminated hollow of the sculpture also produces a unique lighting effect, giving the sculpture an overall translucent appearance. Various embodiments include a plurality of light strings that stem from the main power circuit, with LED lighting elements. The number of lighting elements per light string may be limited to prevent dimming of the lighting elements.
