Light-emitting device

A light-emitting device, comprising:

• a light-emitting element including:
• 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 at least one first conductive frame and having at least one second electrically-conducting portion;
• a casing enclosing the at least one first conductive frame and the at least one second conductive frame, the at least one first electrically-conducting portion, the at least one heat-dissipating portion and the at least one second electrically-conducting portion being exposed from the casing;
• and
• at least one light-emitting chip disposed on the at least one first conductive frame;
• and
• a heat-conducting and electrically-insulating element including at least one heat-conducting and electrically-insulating layer disposed on the at least one heat-dissipating portion for insulating an electrical current from the at least one heat-dissipating portion;
• wherein the light-emitting element has an electrical conduction path passing through the at least one first electrically-conducting portion and the at least one second electrically-conducting portion;
• wherein the light-emitting element has a heat-conduction path passing through the heat-dissipation portion and the heat-conducting and electrically-insulating element.
