Description

LIGHTING FIXTURE WITH MOUNTING INTERFACE

FIELD OF INVENTION The present invention relates generally to a lighting fixture with mounting interface, and more particularly to a lighting fixture with adaptive mounting interface for light source.

BACKGROUND OF INVENTION Lights and light fixtures are frequently used in various architectural structures. Typically, configuration and placement of the lights and Ught fixtures on suspended mechanical ceilings (i.e. drop ceilings) enable to provide illumination effect in responsive to the architecture of a building or other structure. The typical suspended mechanical ceilings normally include recessed lighting fixtures that are configured to be flush with the ceiling. These lighting fixtures, commonly referred to as troffer fixtures, are usually suspended from and secured in the ceiling by a "grid" of T-frames. Said grid of T-frames also serves to suspend the ceiling tiles.

The troffer-type lighting fixtures, however, are comparatively thicker than ceiling tiles and cannot be easily manoeuvred into place and installed under the ceiling. Rather, these lighting fixtures have heretofore been configured above the "grid" and dropped onto position from above the ceiling. Accordingly, the troffer fixtures may often be recessed into the ceiling, with the back side of the troffer protruding into the plenum area above the ceiling. Moreover, installation work performed above the "grid" is cumbersome due to the lighting fixture must be manoeuvred into place above the grid, as such the depth of the mechanical ceiling may need to be increased to allow adequate manoeuvring space. Installations above the grid can also be complicated by nearby obstructions, such as plumbing, and HVAC (i.e. heating, ventilating, and air conditioning) or electrical ducting. With the evolution of lighting, from incandescent to fluorescent and to light-emitting diodes (LED), it has led to the need for improvement to the housing or to the light fixture to accommodate Ught source, while at the same time enables to provide an enclosure for power source or electrical connector. Light intensity, Ught distribution, source position, adjustability and fixture appearance all can be factors in lighting fixture designs. However, such requirements often require flexibility that often difficult to satisfy with a common fixture design. Moreover, additional demands placed on the lighting fixtures and the use thereof may include moisture resistance, maintenance needs and adjustability. All such factors can add to difficulties in design and fabrication of the lighting fixtures.

Furthermore, it is found that many conventional light sources, such as fluorescent tube or LED tube, often require bulky fixture with aluminium reflector, and the installation and/or replacement of such hghts and lighting fixtures may be complicated, cumbersome and time corisuming. Additionally, such a complete system of the lights and lighting fixtures could be costly in term of materials, manufacturing and maintenance costs. Maintenance and cleaning works of such bulky fixtures are not easy and often found to be lack of mounting flexibility that limits the area of Hlumination. In view of these and other shortcomings, it would be desirable to provide a practical and effective lighting fixture for easy and rapid installation. Accordingly, the present invention aims to provide a lighting fixture with mounting interface that lending in both economy of manufacture and simplicity of installation. Moreover, the present invention also facilitates readily and easily assembly as well as enables to provide mounting flexibility at any desired installation area, while at the same time, facilitates rapid and effective installation and easy maintenance.
