Abstract
One embodiment provides a luminaire. The luminaire includes a light transfer structure, and a thermal management structure. The light transfer structure is configured to receive light from at least one light emitting diode (LED). The thermal management structure is configured to manage a thermal energy of the at least one LED. The light transfer structure and the thermal management structure are formed during a same three-dimensional (3D) printing process.
Claims20
A lighting apparatus comprising:
- a light transfer structure configured to receive light from at least one light emitting diode (LED), the light transfer structure comprising at least one light transfer feature;
- and
- at least one thermal management structure configured to manage a thermal energy of the at least one LED, wherein the at least one thermal management structure comprises one or more thermal management elements, at least one of the one or more thermal management elements having thermal management features configured to facilitate heat transfer from the at least one LED,
- wherein the light transfer structure and the thermal management structure are formed at the same time during a same three-dimensional (3D) printing process and in which the light transfer structure and the thermal management structure are integrated with one another as a combined structure, and wherein the thermal management structure further comprises two or more concentric structures, each of the concentric structures being separated from one another by voids, at least one of the two or more concentric structures comprising one or more channels or voids as a thermal management feature for directing airflow.
