The present disclosure is directed to in grade light fixtures and recessed luminaires and subassemblies thereof, including, for example, a heat sink and pivot for a recessed luminaire, a gasket for the recessed luminaire, and an outer box and cover for installation of the recessed luminaire. The recessed luminaire comprises: a housing having an internal surface; and a light subassembly engaged with a thermally conductive body, the light subassembly having a first end and a second end, wherein the first end of the light subassembly is pivotally secured to a pivot arranged on, in, or proximate to the internal surface of the housing. The thermally conductive body is in thermal contact with the internal surface of the housing. The recessed luminaire further comprises a dehumidifier.

A lighting device system has a lighting device module including a movable heat sink member configured to be received within the inner volume of a module housing. At least one rail on an inner surface of the module housing or on the movable heat sink member is received in a corresponding one or more grooves on the other of the inner surface of the module housing or the movable heat sink member. The movable heat sink member is slidably movable along the at least one rail or groove. A light source is attached to the heat sink member for directing light out of the first open end of the module housing, and is movable with the heat sink member to change a tilt angle of the light source.

The present invention relates to a heat sink structure and a flexible light-emitting device with heat sink structures. The heat sink structure according to the present invention dissipates heat through a heat sink part. A hooking part on one end of the heat sink structure hooks a fixing part of another heat sink structure for forming flexible and bendable heat sink structures. Bending the heat sink structures gives a first nonlinear structure. The flexible light-emitting device can be disposed on the heat sink structures. The heat generated by the flexible light-emitting device can be removed by the heat sink structures. The heat sink structures can adapt to lamps with various designs. Then the design freedom and reliability of lamps can be improved.

An aiding device for lamp heat dissipation facilitates the heat dissipation of a lamp. A portion of the lamp has an engaging portion. The aiding device includes an engaging groove, and the engaging groove of the aiding device is adapted to be engaged with the engaging portion of the lamp, so that the aiding device is assembled on the lamp. Accordingly, the temperatures of the power module, the electronic components, or the light emitting components can be reduced through heat dissipation, thereby extending the lifetime of the lamp.
