摘要:
In one aspect, an illumination structure includes a substantially non-fiber waveguide, which itself includes a discrete in-coupling region for receiving light, a discrete propagation region for propagating light, and a discrete out-coupling region for emitting light.
摘要:
An illumination apparatus, comprising at least one light emitting source embedded in a waveguide material is disclosed. The waveguide material is capable of propagating light generated by light emitting source(s), such that at least a portion of the light is diffused within the waveguide material and exits through at least a portion of its surface.
摘要:
A light source device, comprising at least one light emitting element, an optical for distributing light emitted by the light emitting element(s) into a waveguide material which is in optical communication with the optical funnel, and at least one reflector contacting the waveguide material for redirecting light back into the waveguide material such as to reduce illumination exiting the waveguide material in any direction other than a circumferential direction.
摘要:
An illumination system in accordance with an embodiment hereof includes a plurality of LED units, a system controller, at least one sensing unit, and a plurality of local controllers each associated with at least one LED unit. Each LED unit includes a plurality of differently colored, independently controllable LEDs forming a color gamut. The system controller generates control signals for each of the LED units consistent with a desired system-level output. The sensing unit(s) senses an operating state of the LEDs during operation thereof, and each local controller includes a memory and a compensator. The memory includes calibration data for use over a short time period, and the compensator updates the calibration data based on measurements from a sensing unit over a long time period. Based at least in part on the calibration data, the local controller operates the LEDs of the LED unit to maintain output intensities consistent with commands issued by the system controller.

摘要:
An optical coupling apparatus for coupling a waveguide to a light source, when the light source emits light at a divergence angle that is larger than the critical angle of the waveguide. The optical coupler comprises a plurality of light-guides, preferably cut from the edge of the waveguide. The light-guides are arranged to connect the waveguide to the light source via a plurality of orientations so that the entire divergence angle is covered within the critical angle of the light-guides.

摘要:
In one aspect, an illumination source includes a socket formed by the union of a sub-assembly platform and a light-guide element, and a discrete light source received in the socket. In another aspect, the light-guide element includes a concentration region proximate an in-coupling region opposite an out-coupling region, the concentration region directing multidirectional light from the in-coupling region toward the out-coupling region.
