A trim member for a lighting device module includes an annular body having a first end portion that is connectable to a housing of the lighting device module and has a light receiving opening, and a second end portion opposite to the first end portion. The second end portion has a light emitting opening and is configured to be positioned outside of the housing of the lighting device module. A first curved or tapered surface extends from the light receiving opening toward the light emitting opening, and has a diameter that increases toward the light receiving opening. A second curved or tapered surface extends from the first curved or tapered surface to the light emitting opening, and has a diameter that increases toward the light emitting opening.

Disclosed is a night downlight, including a plastic housing, a light source plate, a reflective cup, and a light guide sleeve. The plastic housing is provided with an opening, and the light source plate is arranged on an inner side of the plastic housing opposite to the opening. The light source plate is provided with a first light source and a second light source. One end of the reflective cup abuts against the light source plate. The light guide sleeve is arranged between the other end of the reflective cup and the plastic housing. The light guide sleeve is in snap-fit with the reflective cup. The snap-fit design of the light guide sleeve and the reflective cup allows replacement of the small component rather than replacement of the whole face ring when the snap-fit structure fails, thereby effectively reducing waste in repair and replacement.

A LED (light-emitting diode)-based illumination assembly with an adjustable irradiation angle comprises a conductive threaded protrusion protruding from a hollow cylindrical body and threaded to an electrical bulb-type socket; a vertical elongate guide rod protruding from the base sub-assembly; a fixed LED-module support fixed to a distal end of the vertical elongate guide rod; a movable LED-module support configured to move along the vertical elongate guide rod; a plurality of LED-based illumination modules; a plurality of elongate elastic plate; an irradiation angle adjustment mechanism, wherein the irradiation angle adjustment mechanism is configured to allow operative connection between an outer circumferential surface of the hollow cylindrical body of the base sub-assembly and the movable LED-module support, wherein the irradiation angle adjustment mechanism is configured to allow adjustment of an irradiation angle of the LED-based illumination modules to a selected angle via the operative connection.

A turn signal unit for an external mirror for a motor vehicle is designed to radiate a flashing light forwards in the direction of travel with the turn signal unit and the external mirror in the installation position at the side of the vehicle. The turn signal unit includes a light source and a lens disposed in front of the light source. A film with alternating light transmissive and non-light transmissive structures is clamped in the space between the light source and the lens. The film is clamped via a clamping structure which includes structure that is part of the lens and/or a housing portion of the turn signal unit.

A retrofit kit for a lay-in troffer LED luminaire comprising two sets of connecting beams, with a first set being arranged in a parallel orientation and a second set of connecting beams oriented in a perpendicular manner with respect to each of the first set of beams. Each set of connecting beams are engaged to connected to each other by means of multiple coupling retainers and clamping hooks matched with each other to form a quadrangular bracket capable of containing the troffer. Compressible and extendable fastening means are further placed at the lateral sides of the troffer. And the troffer is connected to the ceiling through the allocation with the bracket by making fastening means aligned with the connecting holes on the first or the second sets of connecting beams that receive the fastening means.

Methods and apparatus for implementing a control apparatus for a light fixture for externally controlling the current to the LED light emitter of a landscape LED light fixture. In an exemplary embodiment a control apparatus for controlling current to an LED light source in a landscape lighting device includes an LED driver, a user control with a control setting indicator, and a driver housing including setting indicators.
