Patent granted for an uplight device for a luminaire
A recently granted patent (Publication Number: US11668443B2) describes an uplight device and a luminaire assembly incorporating this device. The uplight device is designed to be used with a luminaire, which is a lighting fixture, and includes a body with an annular flange and a vertically oriented annular rim. The body is coupled between the stem and housing of the luminaire, allowing it to communicate with the wireway of the stem and the chamber of the luminaire.
The uplight device also features an uplight substrate with a plurality of light emitting sources arranged in an array on one side. An optical lens covers this side of the annular flange and the uplight substrate. The light emitting sources on the uplight substrate are configured to emit light in a direction opposite to the light emitting sources on the luminaire substrate.
The body of the uplight device has a passageway that extends between two open ends. The first portion of the body is threadably coupled to the stem, while the second portion is threadably coupled to the housing of the luminaire. The passageway allows for the routing of electrical wiring between the uplight substrate and the driver of the luminaire.
The luminaire assembly described in the patent includes the luminaire itself and the uplight device. The luminaire has a housing, an optical frame, and a luminaire substrate with light emitting sources. The uplight device is coupled between the stem and housing of the luminaire, with its body communicating with the wireway of the stem and the chamber of the housing.
The luminaire assembly allows for the emission of light in different directions, with the light emitting sources on the uplight substrate emitting light in the opposite direction compared to the light emitting sources on the luminaire substrate. Electrical wiring for the luminaire and the uplight substrate can be routed through the passageway of the uplight device.
Overall, this patent describes an uplight device and a luminaire assembly that provide enhanced lighting capabilities and flexibility in directing light. The design allows for the emission of light in different directions and efficient routing of electrical wiring.
