Abstract:
A light source apparatus including a first heat transfer element, a second heat transfer element, at least one first light emitting element, and at least one second light emitting element is provided. The first heat transfer element has a first carrying surface and a first heat dissipation surface opposite to the first carrying surface. The second heat transfer element surrounds the first heat transfer element and has a second carrying surface and a second heat dissipation surface opposite to the second carrying surface. The thermal resistance of the first heat transfer element is smaller than the thermal resistance of the second heat transfer element. The first and the second light emitting elements are disposed over the first and the second carrying surfaces respectively. The luminance of the first light emitting element is easier to vary with a change of temperature than the luminance of the second light emitting element.
Abstract:
A heat dissipation structure for an ellipsoidal lamp to provide an improved cooling effect for the ellipsoidal lamp has a redesigned shape and installing location for the blower duct that extends the outlet thereof to the edge of effective light beam zone of the ellipsoidal lamp so that the outlet is most close to the hot spots that require heat dissipation. Airflow ejected from the blower duct also is prevented from scattering to improve heat dissipation effect. The outlet may have a guiding plate located therein to channel the airflow close to the hot spots and match the shape of a reflection hood to improve airflow without scattering.
Abstract:
An illumination apparatus includes a housing, a light source, a centrifugal fan, and a heat sink. The housing has an accommodation, a plurality of inlets, and a plurality of outlets. The accommodation communicates with the outside of the housing through the inlets and the outlets. The light source, the centrifugal fan, and the heat sink are disposed in the accommodation. The heat sink includes a base and a plurality of fins connected to the base. The base is connected to the light source, the fins radially surround the centrifugal fan. An air channel is disposed between two adjacent fins. An air from the outside of the housing is capable of flowing into the accommodation through the inlets and then into the centrifugal fan in an axial direction of the centrifugal fan, and flow out of the accommodation in a radial direction of the centrifugal fan through the air channel and outlets.

Abstract:
A loop heat pipe for dissipating heat generated by a heat source includes a pipe, a first capillary structure, a second capillary structure, and a working fluid in the pipe. The pipe has a condensing section, an evaporating section adapted to contact the heat source thermally, and an obstructing section adjacent to the evaporating section. The first capillary structure on an inner surface of the pipe is disposed between the condensing section and the obstructing section. The second capillary structure has a first and a second parts connected with each other. The first part on the inner surface of the pipe is extended from the evaporating section to the obstructing section. The second part passing through the obstructing section is extended from the obstructing section to the condensing section. A space between the first capillary structure and the second part of the second capillary structure defines a compensation room.
