The disclosure provides a luminaire and a luminaire combination. The luminaire combination includes at least two luminaires. The luminaire includes a housing and a light source module received in the housing. The housing defines a connecting groove therein. The connecting groove is in a flat strip shape and extends from an outer surface of the housing. One end of the connecting groove is opened for insertion of a connector. The connecting groove is provided with a limit portion on each of two opposite side walls thereof. A gap between each limit portion and a bottom surface of the connecting groove forms a channel guide. The connector is provided with a connecting portion on each of two opposite sides thereof. The connecting portion is operable to be inserted into and matched with the channel guide corresponding to the connection portion.

Disclosed is a junction device for joining adjacent housing sections of a light fixture housing assembly, having a junction body structure formed from at least one junction body segment. A plurality of coupling units, each with at least one first boundary including at least one male portion or at least one female portion. The male and/or female portions are configured to enable each corresponding portion a first of the coupling units to receive the male portion of a second of the coupling units. Each of at least two of the coupling units including a first segment formed with the at least one junction body segment at respective first boundaries with the corresponding male or female portions extending therefrom. Each of the male and female portions is configured to be associated with a first locking structure to lock the female and male portions together to form the assembled light fixture housing.

A lighting device produces scenic effects including a light source group; a light guide extending along a longitudinal axis and coupled to the light source assembly defining an optical path; a primary mirror arranged along the longitudinal axis facing the light source assembly to reflect the light beam from the light guide; and a secondary mirror facing the primary mirror to reflect the light beam reflected by the primary mirror towards an emission area surrounding the primary mirror, wherein a primary reflecting surface of the primary mirror has at least one first portion having a first hyperbolic shape or a first aspherical shape of even order and degree equal to or greater than four and a secondary reflecting surface of the secondary mirror has at least one second portion having a second hyperbolic shape or a second aspherical shape of even order and degree equal to or greater than four.

An improved decorative lighting system constructed having a support framework assembly for mounting decorative lights in connection with a window frame. The support framework assembly comprises a plurality of tubular track members, each formed having a slotted chamber section extending the length of the track member with a squared outer edge formed along either side at the base of the chamber to provide a substantially flat planar surface along the base of the track member. A plurality of articulating end clips are formed to engage each track member and interconnect with another to join the track members in a substantially rectangular configuration adjustable to conform to the shape of the window frame. A plurality of specially configured light mounting clips are formed to press-fit and slide along the flat perimeter surface of the track members and hold the decorative lights in selected positions along the track members. Ring members included upon selected ones of the articulating end clips are used and positioned in upper corners of the framework assembly to engage conventional hooks or tabs secured to the window frame and facilitate the mounting of the framework assembly and its removal and storage when desired. The articulating end clips further allow the complete support framework assembly to fold and store more easily.
