Hinged channel system for linear lighting
A channel system that includes a first channel section, a second channel section, and a hinge joint between the first and second channel sections is disclosed. The hinge joint allows the first channel section to fold against the second channel section for storage and shipping of the channel system. In one embodiment, the hinge joint itself includes a hinge member that extends between the two channel sections and bends hingedly to allow movement and two intermediate endcaps, which cap the channel sections on either side of the hinge joint. The hinge joint may be designed to “snap back” to a fully extended position. Mechanical securement structure may be added to the first channel section and the second channel section to improve force and retention during the “snap back” movement.
1. A collapsible and self-straightening luminaire, comprising:
a pair of elongated channels mechanically linked to each other in end-to-end fashion at a hinge joint; and
a length of linear lighting disposed within each of the elongated channels;
wherein the hinge joint comprises an inherently resilient hinge member extending between and attached to each of the pair of elongated channels,
wherein the collapsible and self-straightening luminaire has a first, folded-over configuration and a second, straightened configuration; and
wherein when the collapsible and self-straightening luminaire is in the first, folded-over configuration, a restoring moment that acts in a direction tending to cause the elongated channels to pivot back into alignment with each other and that is caused by the inherent resiliency of the hinge member exists within the hinge member.
2. The collapsible and self-straightening luminaire according to claim 1 , wherein the inherently resilient hinge member comprises an elongated strip of material with a convex camber that allows the elongated strip of material to be bent out of a straight configuration when subjected to a bending moment and that causes the restoring moment such that the elongated strip of material snaps back to its straight configuration when the bending moment is removed.
3. The collapsible and self-straightening luminaire according to claim 2 , wherein the inherently resilient hinge member is metal.
4. The collapsible and self-straightening luminaire according to claim 1 , wherein the elongated channels have respective abutting ends and the collapsible, self-straightening luminaire further comprises an end cap disposed at each of the abutting ends of the elongated channels, with the inherently resilient hinge member extending through each end cap.
5. The collapsible and self-straightening luminaire according to claim 1 , wherein the elongated channels have respective abutting ends and the collapsible, self-straightening luminaire further comprises mechanical securement structure located at each of the abutting ends of the elongated channels, the securement structure being configured and arranged to augment the restoring moment of the inherently resilient hinge member to hold the elongated channels in alignment with each other.
6. The collapsible and self-straightening luminaire according to claim 1 , wherein the lengths of linear lighting disposed within the pair of elongated channels are electrically connected to each other across the hinge joint.
