The present disclosure relates to a lighting system. The lighting system may include a first housing, a second housing, one or more drivers, and one or more lighting devices. The first housing defines a first hollow portion. The second housing may be pivotably coupled to the first housing and define a second hollow portion opposite to the first hollow portion, such that the first hollow portion and the second hollow portion together define an interior space. Further, the one or more drivers may be disposed in the first hollow portion of the first housing. Moreover, the one or more lighting devices may be disposed in the second hollow portion of the second housing and electrically connected to the one or more drivers.

A trim attachment system includes a light fixture housing and a first coiled spring bracket having a first coil section and a first elongated section. The first elongated section is positioned in the light fixture housing and attached to the light fixture housing, where the first coil section is attachable to a trim to pull up the trim toward an opening of the housing. The trim attachment system further includes a second coiled spring bracket having a second coil section and a second elongated section. The second elongated section is positioned in the light fixture housing and attached to the light fixture housing, where the second coil section is attachable to the trim to pull up the trim toward the opening of the housing.

LEDs (21) that emit illumination light and a cover unit (30) that houses the LEDs are provided. The cover unit is composed of a front cover part (31) that transmits, diffuses and reflects the illumination light from the LEDs and a rear cover part (32) that reflects the illumination light reflected at the front cover part again toward the front cover part. The front cover part and the rear cover part are integrally molded without a gap and the loss of light fluxes is therefore eliminated. Moreover, the uniformity of luminance distribution of the light-emitting surface is improved to solve the problem in that the side surfaces of the lighting device and the attaching surface (ceiling surface) are dark.

Systems are provided for an optical device. The optical device comprises a lens actuation system including a motor, a flywheel, a connecting linkage, a plurality of articulating arms, and a lens. The lens is housed in a frame coupled to the articulating arms and driven via the lens actuation system between an upstream position and a downstream position.

A trim retention assembly (280) for a recessed luminaire (100) comprising aretention device anchor (328) and a retention device retaining feature (329) both disposed in the recessed luminaire (100), retention device coupling feature (755) disposed on a trim (749), andretention device (330) having aluminaire anchor (335), resilient feature (334), luminaire retention feature (333), andtrim coupling feature (331), where the i) luminaire anchor is coupled to the retention device anchor, ii) trim coupling feature is coupled to the retention device coupling feature, iii) resilient feature has a loaded position and an unloaded position, iv) retention device retaining feature holds the resilient feature in the loaded position, v) trim coupling feature is disposed below a structure (159) when the resilient feature is in the loaded position, and vi) resilient feature pulls the trim against the structure when resilient feature is in the unloaded position.

The first housing defines a first hollow portion. The second housing may be pivotably coupled to the first housing and define a second hollow portion opposite to the first hollow portion, such that the first hollow portion and the second hollow portion together define an interior space. Further, the one or more drivers may be disposed in the first hollow portion of the first housing. Moreover, the one or more lighting devices may be disposed in the second hollow portion of the second housing and electrically connected to the one or more drivers.

Systems are provided for an optical device. The optical device includes a light emitting diode in face-sharing contact with a light mixing rod. A resilient member is configured to maintain the light mixing rod in face-sharing contact with the light emitting diode throughout a range of motion of the optical device.
