Abstract

The invention provides an outdoor illuminating apparatus which includes a housing, a heat-conducting device, a light-emitting device, and an adaptor. The housing includes a space. The heat-conducting device is disposed in the space and includes a flat portion and a touching portion. The touching portion touches the housing. The light-emitting device is disposed on the flat portion and includes at least one light-emitting chip. The adaptor is engaged to the housing and includes a passage. Therein a light-guiding member could be engaged to the passage and be sealed therewith for guiding light emitted by the light-emitting chip. The housing can be assembled with a tubular body, a first cover, and a second cover, so as to form the space sealed substantially. The tubular body can be formed in one piece and a plurality of fins can be formed thereon at the same time to enhance heat-dissipating efficiency.
