An installation mechanism of LED lighting includes a house and a mounting plate. The house includes a mounting slot provided on a side wall along a radial direction thereof. The mounting slot includes a implantation portion and a catch portion communicating with the implantation portion. The catch portion includes at least one catching arm provided on one of two opposite side walls thereof. The mounting plate includes two catch edges inserted in the catch portion. The implantation portion is configured for presetting the mounting plate. Each of the catch edge has a Z-typed shape in a cross section of the mounting plate along the axial direction thereof. A free edge of the Z-typed catch edge is inserted into a gap between the catching arm and the bottom of the mounting slot.

The present disclosure provides an LED luminaire capable of providing full cutoff illumination in a base configuration, without the addition of reflectors or refractors. The LED luminaire is also interchangeably couplable to one or more different reflectors and refractors. In certain example embodiments, the present disclosure provides a dusk to dawn luminaire operable as a full cutoff luminaire in a base configuration and which is also compatible with an American Nation Standards Institute (ANSI) dusk to dawn reflector/refractor assembly. In an example embodiment, the LED luminaire also includes a housing with a front pivoting door configured to swing away from a mounting structure when opened.

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.
