FIELD OF THE INVENTION

This disclosure described herein relate to a light fixture and a method of mounting a light fixture.

BACKGROUND

To mount, for example, a square lighting device in a ceiling, a method is performed in which a quadrilateral hole matching the shape and the size of a lighting main body is formed in the ceiling. The lighting main body is fixed to a suspension bolt, which is a ceiling component. Such light fixtures may be subject to drooping at theirs ends, allowing for the entrance of foreign matter into the back of the light fixture. Additionally, fixtures mounted in holes matching the size and shape of the fixture may be more likely to fall from their mounted positions.

SUMMARY OF THE INVENTION

In an aspect, a light fixture assembly for mounting on a mounting surface of a building material includes a light fixture having a main body, a mounting adapter, and a plate spring. The main body includes a back side surface and a light transmissive side surface opposing the back side surface. Further, the main body has a first dimension from a first lateral edge to a second lateral edge opposing the first lateral edge. The first dimension is greater than a second dimension from the back side surface to the light transmissive side surface. The mounting adapter is provided at the back side surface, and the plate spring extends along a first direction from the first lateral edge to the second lateral edge. The plate spring is configured to apply a restoring force to the first lateral edge and the second lateral edge.

In another aspect, a light fixture assembly for mounting on a mounting surface of a building material includes a light fixture having a main body, a mounting adapter, a plurality of light sources, and a plurality of protrusions. The main body includes a back side surface and a light transmissive side surface opposing the back side surface. The main body has a first dimension from a first lateral edge to a second lateral edge opposing the first lateral edge. The first dimension is greater than a second dimension from the back side surface to the light transmissive side surface. The mounting adapter is provided at the back side surface of the main body. The plurality of light sources is provided on a surface of the main body that is between the between the back side surface and the light transmissive side surface, and the plurality of light sources is arranged to emit light towards the light transmissive side surface. The plurality of protrusions is provided on the surface of the main body and arranged laterally between the plurality of light sources.

In another aspect, a method of mounting a light fixture includes fitting a tubular portion of a power supply adapter into a mounting hole formed in a building material, and disposing a power supply unit of the power supply adapter in a space backward of the building material. The power supply unit is provided above the tubular portion. A mounting adapter is fit into the tubular portion of the power supply adapter fitted into the mounting hole. The mounting adapter is provided at a back side surface of a light fixture main body, the light fixture main body including a light source module and a cover, the light source module including a plurality of light sources disposed in a region larger than a plane area of the mounting hole, the cover covering the light source module and being transmissive.

To provide an overall understanding of the systems, methods, and devices disclosed herein, certain illustrative embodiments will be described below. Although the embodiments and features described herein are specifically described for use in connection with a light fixture, it will be understood that the teachings may be adapted and applied to other mounting systems.
