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.

An enclosure for recessed lighting, comprising a lateral wall, a top wall and a removable and re-attachable enclosure base, the enclosure base includes a light source, power supply, optic, heat sink and a collar. The enclosure may include an integral junction box, or hangar bar bracket, and one or more cutouts to reduce the possible interference between enclosure and joists in the installation vicinity. The enclosure may be made out of a 3D printable material, moldable material or plastic to facilitate ease of manufacture, reduction of parts, reduction of weight, and elimination of finish steps, such as paint. Multiple enclosures may be stacked for shipping or storage, and hanger bars may be affixed to the lateral wall for installation of the enclosure in a ceiling or wall without the need for a secondary bracket.

A reflector and of a holding-plate slidingly attach to each other to form a flangeless trim assembly. The reflector may be removably attached to a spackle-frame. The spackle-frame may be installed within ceiling drywall around a hole for a downlight. The holding-plate may be attached to a lighting module. In a default resting configuration, a top of the reflector butts up against a bottom of the holding-plate because springs push these two parts towards each other. When an opposing force is applied that is greater than the spring's force, then a variable gap is formed between the reflector and the holding-plate, but while the reflector and the holding-plate are still attached to each other. This gap may be used by human finger(s) to both disengage the reflector from the spackle-frame and to pull down the reflector, the holding-plate, and the lighting module from the spackle-frame—all without tools.

The present disclosures provides a collar for positioning at least partially around a recessed light fitting and between the recessed light fitting and a structural body. The collar comprises a plurality of collar portions each of which are configured to surround a portion of the recessed light fitting.

A downlight apparatus includes a light source, a driver, a light holder, a metal rim and two elastic arms. The driver converts an external power to a driving current to be used by the light source. The light holder stores the light source in an holder space of the light holder. The light holder is placed inside a cavity of a ceiling. The metal rim is connected to a bottom side of the light holder. The two elastic arms are attached to one of the metal rim and the light holder for elastically pressing the metal rim to engage an cavity edge of the cavity of the ceiling for concealing the cavity and preventing an accidental fire to escape from the cavity of the ceiling to outside of the cavity of the ceiling.

An LED downlight assembly accommodates square and round trims and its components may be removed irrespective of the presence of mudded in round or square mud plates. The assembly also comprises a collar that can be fitted to ceiling of varying thicknesses.
