Abstract
A luminaire having a waveguide suspended beneath a mounting element, the waveguide has a first surface proximal to the mounting element, a second surface distal to the mounting element, and an edge between the first and the second surfaces. At least one cavity extends into the waveguide from the first surface to the second surface. A LED component is coupled to the waveguide so as to emit light into the cavity. LED support structures are also disclosed.
Claims61
A luminaire, comprising:
- a waveguide suspended distal to a mounting element, said waveguide having a first surface proximal to the mounting element, a second surface distal to the mounting element, and an edge between the first and the second surfaces;
- at least one coupling cavity extending into the waveguide from the first surface toward the second surface;
- and
- an LED component associated with the waveguide so as to emit light into the at least one cavity.
An LED support structure for use in a cavity in a waveguide, the LED support structure comprising:
- a first surface;
- a plurality of LED devices mounted on the first surface;
- an elongate reflective member extending outwardly from between the plurality of LED devices;
- and
- a reflective element attached to an end of the elongate reflective member opposite the first surface.
An LED support structure for use in a cavity in a waveguide, the LED support structure comprising:
- a first cap assembly comprised of:
- a base member;
- a LED mounting member extending from the base member;
- and
- at least one LED mounted on an end of the mounting member distal to the base member.
A luminaire comprising:
- a waveguide suspended distal to a mounting element, said waveguide having a first surface proximal to the mounting element, a second surface distal to the mounting element, and an edge between the first and the second surfaces;
- at least one cavity extending into the waveguide from the first surface to the second surface;
- and
- at least one LED component connected to a first bar assembly, said at least one LED component associated with the first surface of the waveguide so as to emit light into the at least one cavity.
