Abstract
A light-emitting device includes a light-emitting element and a heat-conducting and electrically-insulating element. The light-emitting element includes at least one first conductive frame having at least one first electrically-conducting portion and at least one heat-dissipating portion, at least one second conductive frame adjacent to the first conductive frame and having at least one second electrically-conducting portion, a casing enclosing the first conductive frame and the second conductive frame, and at least one light-emitting chip disposed on the first conductive frame. The heat-conducting and electrically-insulating element includes a heat-conducting and electrically-insulating layer disposed on the heat-dissipating portion for insulating an electrical current from the heat-dissipating portion. Hence, the instant disclosure can plan a heat-conduction path and an electric-conduction path for the light-emitting chip to effectively increase the heat-dissipating efficiency of the light-emitting element due to the design of placing the heat-conducting and electrically-insulating layer on the heat-dissipating portion.
