A solid state lighting device includes a heat-dissipating base, a diode chip, and a plurality of conductive terminals. The heat-dissipating base includes a base body formed integrally from a thermally conductive material. The base body has a top side, and is formed with a cavity that is indented from the top side. The base body further has a plurality of terminal channels, each of which extends from the cavity to an exterior of the base body. The diode chip is disposed in the cavity. Each of the conductive terminals extends through a respective one of the terminal channels, and has a first connecting part that is disposed in the cavity and that is coupled electrically to the diode chip, and a second connecting part that is disposed outwardly of the heat-dissipating base.

A lens includes a lens body having a bottom surface, a reflective surface, and a refractive surface. The bottom surface is to be disposed proximate to a light-emitting component. The reflective surface is disposed opposite to the bottom surface along a lens axis, and reflects a first portion of the light provided by the light-emitting component that is incident thereon toward the refractive surface. The refractive surface extends from an edge of the reflective surface to the bottom surface, and refracts a second portion of the light provided by the light-emitting component that is incident thereon as well as the first portion of the light reflected by the reflective surface theretoward in sideward directions relative to the light-emitting component. The lens body has cross-sections transverse to the lens axis, sizes of which increase gradually from a junction of the reflective surface and the refractive surface toward the bottom surface.

A SMD-type LED with high heat dissipation efficiency and high power includes a base with a post arranged and integrated on the center thereof and a slot on top of the post. At least one contact hole is arranged on bottom of the base for connecting with an external heat sink so as to achieve better heat dissipation. The slot is used for accommodating a LED chip that is electrically connected with a circuitry extension device through two electrical contacts. The LED chip is electrically connected with the circuitry extension device directly while it also connects with the base for heat dissipation, thus the structure for electricity conduction is separated from the structure for heat dissipation.
