Abstract

A recessed downlight integrates a light engine assembly with a junction box containing a driver assembly. A single torsion spring is supplied at an end of the light engine assembly remote from its connection to the junction box, while a leaf spring attaches to the junction box near its connection to the light engine assembly, or is alternatively integrated into an extension of the junction box. The leaf spring allows for a high-enough tension to hold the light unit assembly in place in thin sheet metal, while allowing for a low-enough tension to accommodate holding the light unit assembly in place in drywall or a drop ceiling.

Claims

1. A recessed downlight comprising:

a light engine assembly; and

a driver assembly that is mechanically connected to the light engine assembly;

wherein a torsion spring is supplied at an end of the light engine assembly at a farthest point from its mechanical connection to the driver assembly; and

wherein a leaf spring is supplied at the driver assembly adjacent to its mechanical connection to the light engine assembly.

2. The recessed downlight of claim 1, wherein the leaf spring is removable from the driver assembly.

3. The recessed downlight of claim 1, wherein the leaf spring is an integral part of the driver assembly.

4. The recessed downlight of claim 1, wherein an electrical connector is provided between the light engine assembly and the driver assembly.

5. The recessed downlight of claim 1, wherein the leaf spring allows for a high-enough tension to hold the light unit assembly in place in thin sheet metal, while allowing for a low-enough tension to accommodate holding the light unit assembly in place in drywall or a drop ceiling.

6. The recessed downlight of claim 1, wherein a horizontal centerline of the driver assembly intersects the light engine assembly at an angular offset from a horizontal centerline of the light engine assembly that passes through the torsion spring and the leaf spring.

7. The recessed downlight of claim 1, wherein the mechanical connection between the driver assembly and the light engine assembly includes a hinge that allows for a rotation between the driver assembly and the light engine assembly.

8. A recessed downlight comprising:

a light engine assembly; and

a driver assembly that is mechanically connected to the light engine assembly;

wherein the light engine assembly comprises a circular base on a first horizontal plane, the circular base configured to be mounted in a soffit, above drywall, or above a dropped ceiling;

wherein the driver assembly comprises an enclosure with a bottom portion comprising a second horizontal plane; and

wherein the mechanical connection between the light engine assembly and the driver assembly comprises a vertical offset such that when the light engine assembly is mounted, the second horizontal plane is at a higher elevation than the first horizontal plane.

9. The recessed downlight of claim 8, wherein an electrical connector is provided between the light engine assembly and the driver assembly.

10. The recessed downlight of claim 8, wherein the mechanical connection between the driver assembly and the light engine assembly includes a hinge that allows for a rotation between the driver assembly and the light engine assembly.

11. The recessed downlight of claim 8, wherein a torsion spring is supplied at an end of the light engine assembly at a farthest point from its mechanical connection to the driver assembly;

and wherein a leaf spring is supplied at the driver assembly adjacent to its mechanical connection to the light engine assembly.

12. The recessed downlight of claim 11, wherein a horizontal centerline of the driver assembly intersects the light engine assembly at an angular offset from a horizontal centerline of the light engine assembly that passes through the torsion spring and the leaf spring.
