Abstract:
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.
