After having adopted above structure, the heat that led light source assembly and LED driven unit are produced can dispel the heat to the external world efficiently by radiator.

The lamp body bottom can be provided with the groove that caves inward, and fin is located in this groove.

Fin can be radial, parallel strip or circular.

Can be provided with sealing ring between panel and the lamp body end face, the through wires hole place can be provided with water joint.Can make this buried shot-light have water-proof function like this.

Management device can be lens or reflector.

The LED driven unit is provided with temperature-control circuit.In use can the temperature of light fixture be automatically adjusted the service life of protection electric elements and prolongation light source.

The led light source assembly can comprise monochromatic light, polychromatic light combination gradual change or saltus step LED.

LED can be for more than single or single in the led light source assembly.

Built-in fitting is cylindric, and its lower surface is provided with flange, is provided with orifice plate in the upper port, and orifice plate is provided with positioner, and lamp body passes from orifice plate, and panel is pressed on the orifice plate and with the orifice plate screw and is connected.
