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.

A light converter comprises: a solid-state optical member configured to absorb light of an excitation wavelength and generate light of an emission wavelength; a base; and a mechanical fastener attaching the solid-state optical member to the base. The light converter may be part of a light engine, a phosphor wheel or an automotive headlight. A method of manufacturing such a phosphor wheel is also provided.

A lighting appliance (1) comprises a light module (2) having a base (6) designed to receive a handle (5) provided with a grip stick (10), the handle (5) being arranged such that it can be inserted axially in removable manner into a ring (7, 7) arranged on the base (6). The handle (5) is withdrawn axially from the base (6) by turning the ring (7, 7) relative to the base (6).

A light fixture which is configured to be embedded in a surface is provided. The light fixture includes a light source and a front panel located in front of the light source. A frame is in contact with a front panel surface of the front panel. A pressure mechanism is configured to press the front panel surface against the frame. A fixing piece is provided at a position opposite to the front panel. The fixing piece extends outward from the base surface side to fix the frame to an external structure. The pressure mechanism is retractable by a distance greater than a thickness of the front panel when a pushing force is applied to the front panel surface. The front panel is movable in a direction perpendicular to a retractable direction of the pressure mechanism when the pressure mechanism is retracted.

A light fixture includes a housing having sidewalls that define a manifold aperture, extending from upper to lower edges of the manifold aperture. The housing includes first coupling features. The light fixture includes at least one adapter plate with second coupling features that removably couple with the first coupling features. The adapter plate defines an adapter plate aperture. At least one light emitting engine removably couples with the adapter plate such that emitted light passes through the adapter plate aperture. The light fixture further includes a baffle that includes at least one baffle cell. The baffle cell includes an upper baffle edge that defines: an upper baffle aperture through which light emitted by the light engine passes, a lower baffle edge that defines an output aperture for the emitted light, and a baffle cell wall that extends from the upper baffle edge to the lower baffle edge.

A baffle for use in a light fixture that includes one or more light emitter positions includes one or more upper edges, each of the upper edges encircling a light emitting aperture and lying within an upper region. The baffle also includes one or more lower edges that correspond in number with the one or more upper edges, each lower edge lying within a lower region, and encircling an output aperture. Plan view shapes of the upper and lower edges form closed shapes that are devoid of angles. The baffle further includes an interior baffle surface that extends downwardly from each of the upper edges to corresponding ones of the lower edges. The interior baffle surface is continuously and downwardly concave from each of the upper edges to each of the lower edges, and is devoid of angles.

A retainer ring for a light fixture includes a cylindrical main body section that defines a cylindrical axis, and an inner retaining flange that extends radially inward from a distal end of the main body section. The inner retaining flange extends substantially about a circumference of the distal end. One or more coupling features extend radially inward from the retainer ring. A customization kit for a light engine that defines an optical axis includes a retainer ring configured to couple with the light engine, and two or more primary optics that are mechanically compatible with the light engine, and retainable to the light engine with the retainer ring. When the retainer ring couples with the light engine, a cylindrical axis of the retainer ring coincides with the optical axis.

A downlight fixing structure is provided. The downlight fixing structure comprises a housing and a spring. The housing is for accommodating light components. The housing has an insertion lock structure on a side of the housing. The spring comprises a coil portion, a head portion, and a tail portion. The coil portion, the head portion and the tail portion are formed by the same metal wire. The head portion is inserted into the insertion lock structure.

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 novel pool light comprises a power supply device, a lighting device, and a power cable mounted between the power supply device and the lighting device. The lighting device comprises a light fixture and a cable winding mechanism for winding the power cable. The cable winding mechanism comprises a rotating member having one side fixedly connected to the light fixture and a base plate rotatably connected to the other side of the rotating member, and a recess between the periphery of the rotating member and the periphery of the base plate forms a cable trough allowing the power cable to be wound therein.
