1. An illuminating equipment, comprising:
- a housing thereon defining a head end;
a reflector, disposed in the housing and near the head end, the reflector having an aperture;
a packaged system, disposed in the housing, comprising;
a casing;
a heat-conducting device, disposed in the casing, having a flat portion, the heat-conducting device being a hollow chamber, therein placed a working fluid and disposed a capillary structure;
at least one heat-dissipating fin, disposed in the casing and mounted on the periphery of the heat-conducting device; and
a light-emitting apparatus, mounted on the flat portion of the heat-conducting device and disposed through the aperture to an optical center of the reflector, for emitting a light in a form of point light source, and the light-emitting apparatus comprising;
a substrate with a plurality of positioning contours thereon;
a plurality of semiconductor light-emitting apparatuses, each semiconductor light-emitting apparatus being disposed within and encompassed by one of the plurality of positioning contours;
a substrate carrier accommodating the substrate;
an optical lens disposed above the substrate and on the peripheral of the substrate carrier such that the plurality of semiconductor light-emitting apparatuses are disposed within a seal space among the substrate, the substrate carrier and the optical lens; and
two electrodes, respectively disposed on the substrate and electrically connected to each of the plurality of semiconductor light-emitting apparatus; and
a power supply, electrically connected to the light-emitting apparatus, for providing the light-emitting apparatus with the power when emitting the light;
wherein a heat, generated during the operation of the light-emitting apparatus, is conducted by the flat portion to the at least one heat-dissipating fin, and then is dissipated by the at least one heat-dissipating fin.

Abstract
The invention provides a packaged system that is suitable for a LED package of high power. The packaged system further includes a heat-conducting device surrounded by at least one heat-dissipating fin to effectively dissipate the heat generated by the high power LED package. The packaged system with high efficiency of heat dissipation can be incorporated into various projecting illuminating equipments, such as a flashlight or floodlight, by simply installing the present invention into a housing and providing power connection thereto.
