A downlight apparatus has a major housing, multiple hook slots, and multiple hooks. The major housing has a surface ring and a main cup. The main cup contains a LED plate and a driver circuit. The LED plate emits light through an opening of the surface ring. The multiple hook slots are located surrounding the main cup. The multiple hooks have bottom hooks inserted and locked in corresponding hook slots respectively and have top hooks to fix the major housing on a ceiling.

An adjustable assembly for an adjustable downlight fixture assembly with a heatsink comprising a plurality of cooling fins that is connected to a mounting bracket where the heatsink is tiltably engaged with the mounting bracket. The heatsink is configured to receive a light source and may tilt within a confined space of the downlight fixture assembly up to 45 degrees from a vertical plane. The mounting bracket comprises a first side wall and a second side wall with a front wall connected between them where the first side wall and second side wall are connected to a rotation ring that is rotatably engaged with the frame of the downlight fixture.

A recessed light fixture configured to deliver indirect light to an area. The recessed light fixture includes a trim component, a reflector coupled to the trim component, and an annular ring including a plurality of light-emitting diodes (LEDs). The trim component has an outer wall and an inner wall spaced radially inward of the outer wall, and defines an annular recess between the outer and inner walls. The reflector includes a patterned reflective surface. The annular ring is arranged within the annular recess of the trim component. The LEDs are configured to emit light toward the reflector so that the reflector redirects the light to deliver the indirect light to the area.

A ceiling grid system formed of struts has a plurality of elongate insert light units. The grid system suspended from the ceiling and comprising a multiplicity of steel elongate channels (struts) arranged in the grid. The channels having a downwardly directed U-shape and defining an opening and an open channel interior, the channel having opposing J-shaped wall portions, each wall portion with an inwardly directed curved lip portion defining a gap width therebetween the two wall portions. The elongate insert light units seated within one of the steel elongate channels, each insert light unit having an elongate body with a light emitting side, each insert light unit comprising a housing, and a strip of light emitting diodes, and a transmission portion at the light emitting side, the body retained in the interior of the channel, each light unit removable and replaceable with the respective channel.

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 lamp includes a main body, a lighting assembly, a lampshade assembly, and a reflector cover. The main body includes a heat sink and a lamp holder, the bottom of the heat sink extends outwardly to form a flange, the lamp holder has a trumpet shaped structure, a bottom of the lamp holder has a minor axis along a longitudinal direction and a major axis along a transverse direction. The lighting assembly is mounted to the bottom of the lamp holder. The lampshade assembly includes a cover body covering the lamp holder and a spring located in the cover body. The reflector cover includes a sleeving portion and an embedded portion, an inner diameter of the embedded portion is less than the major axis of the bottom of the lamp holder, and is greater than the minor axis.

Disclosed in the present invention is a method for adjusting a color temperature of an LED in a single light fixture. In the method, at least two light-emitting modules in a single light fixture are respectively electrically connected to a switch, each light-emitting module is independently adjusted by a switch corresponding to the light-emitting module, and the light-emitting modules have different color temperatures. Therefore, the brightness of each light-emitting module can be respectively controlled by using each switch, so that emitted light of the single light fixture has more than three color temperatures.

A lighting apparatus includes a light source, a light housing, a sliding track, a first sliding unit, a first holder, a second sliding unit, a second holder, a first fixing unit and a second fixing unit. The light housing has a back cover and container. The container has a light opening. The light source is placed in the container and emits a light through the light opening. The sliding track is disposed on the back cover. The first sliding unit is movable along the sliding track. The first holder has a bottom end fixed to the first sliding unit. The second sliding unit is movable along the sliding track. The second holder has a bottom end fixed to the second sliding unit. The first fixing unit is fixed to the first holder. The second fixing unit is fixed to the second holder.

A ceiling lamp mounting structure and a ceiling lamp. The ceiling lamp mounting structure comprises a bottom frame assembly, a sliding assembly and a connecting assembly, the bottom frame assembly being fixed on a mounting wall, the connecting assembly being fixedly connected to a lamp body, and the connecting assembly being detachably connected to the bottom frame assembly by means of the sliding assembly. The sliding assembly comprises a sliding rail and a sliding rod, the sliding rail being fixedly connected to the bottom frame assembly, one end of the sliding rod being movably connected to the sliding rail, and the other end of the sliding rod being rotatably connected to the connecting assembly.

An assembling mechanism for LED downlight includes a cylindrical body, at least one spring fixed on the cylindrical body, and a cover assembled on the at least one spring. Each of the at least one spring includes a fixing portion, a reed extending from the fixing portion along a rotation direction of the cylindrical body, and a catching portion disposed on the reed. The catching portion extends along the radial direction of the cylindrical body. The cover includes at least one clamping gap. Each of the at least one clamping gap includes an open provided along the rotation direction of the cylindrical body. The catching portion is inserted into the clamping gap from the opening by rotating the cover.
