    • A light-emitting device may include a heat-dissipating base, a light-emitting unit, a housing, and a first conductive contact and a second conductive contact. The heat-dissipating base has a top portion and a bottom portion. The bottom portion of the heat-dissipating base may include an exposed heat-dissipation surface. The light-emitting unit is over the top portion of the heat-dissipating base and is arranged to provide heat conductivity at least from the light-emitting unit to the heat-dissipating base. The light-emitting unit may include at least one light-emitting diode for emitting light and a first electrode and a second electrode. Heat may be generated as the light-emitting diode emits light, and the at least one light-emitting diode may have power input terminals for receiving power input to the at least one light-emitting diode. The power input may include one of an alternating-current input and a direct-current input. The first electrode and the second electrode are electrically coupled with the input terminals of the at least one light-emitting diode. The housing encloses at least a portion of the light emitting unit and covers the top portion of the heat-dissipating base. The first conductive contact and the second conductive contact are near or below a portion of the heat-dissipating base and are configured to receive external power supply. The first conductive contact may be electrically coupled with the first electrode, and the second conductive contact may be electrically coupled with the second electrode.
