Abstract: 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.

Abstract: A patient lift apparatus designed to lift and transfer patients is provided. The patient lift apparatus includes a patient lift base and a modular patient support device removably connected to the patient lift base to support a patient. The patient lift base includes a cantilever element, a portal frame, three wheel assemblies, a hanging mechanism. The cantilever element is pivoted intersectionally with the portal frame. The three wheel assemblies are disposed at the bases of the cantilever element and the portal frame, as three bearing points. The hanging mechanism is pivoted to the top of the cantilever element and connected to the modular patient support device below. When the cantilever element and the portal frame are rotated relatively, the height, the shape and the positions of the bearing points of the patient lift apparatus are changed accordingly.
