Abstract
Illumination apparatus includes a support structure, at least one light emitting element, and a heat sink thermally coupled to the light emitting element. The light emitting element and heat sink are moveable in relation to the support structure. An actuator system moves the at least one light emitting element and the heat sink with respect to the support structure.
Claims5
An illumination apparatus, comprising:
- a support structure;
- at least one light emitting element;
- a heat sink thermally coupled to said at least one light emitting element, said at least one light emitting element and said heat sink being moveable in relation to said support structure;
- an actuator system operatively associated with said at least one light emitting element, said actuator system being configured to move said at least one light emitting element and said heat sink with respect to said support structure such that air flow is induced around said heat sink and thermal cooling thereof is effected;
- wherein said light emitting elements are arranged in a plurality of rows, and wherein said heat sink comprises a plurality of heat sinks mounted to said rows of light emitting diodes, said rows of light emitting elements and said heat sinks being independently moveable with respect to said support structure.
2 more elements
A method, comprising:
- mounting at least one light emitting element with a heat sink to a support structure so that said at least one light emitting element and said heat sink are movable with respect to said support structure;
- and
- moving said at least one light emitting element and said heat sink with regard to said support structure such that air flow is induced around said heat sink and thermal cooling thereof is effected;
- wherein said moving step comprises linearly moving said at least one light emitting element and said heat sink with regard to said support structure.
