Abstract:
1. A lamp socket, comprising: a first shell; a second shell combined with the first shell; a separation plate rested on a bottom of the first shell and the second shell; a base secured to the separation plate; an electronic unit mounted in the first shell and electrically connected to the base to supply an electric current to the base; a light-regulating unit mounted in the second shell and electrically connected to the electronic unit to regulate the electric current from the electronic unit to the base; wherein: the first shell has an inside formed with a receiving chamber having an open bottom to receive the electronic unit, a top face formed with a slot, and a first side formed with a passage connected to the slot, the first side of the first shell has a bottom formed with an opening; the electronic unit includes a circuit board mounted in the receiving chamber of the first shell and having a side formed with a first hole and a second hole exposed from the opening of the first shell, a plurality of electronic parts mounted on the circuit board, and a conducting plate secured to the circuit board and electrically connected to the electronic parts; the second shell has a first side formed with a first receiving recess and a second receiving recess connected to the first receiving recess and a second side formed with a through hole connected to the first receiving recess, the second shell has a top face formed with a slot and has an inside formed with a receiving channel having a first end connected to the slot and a second end connected to the bottom of the second shell; the lamp socket further comprises an electrically connecting member mounted in the receiving channel of the second shell and having an upper end provided with an electrically connecting plate having an electrically connecting terminal aligning with the slot of the second shell and a lower end provided with a clamping plate; the light-regulating unit includes an electrically connecting body, a regulating module, a first connecting member, a second connecting member, a pivot arm, a torsion spring, a rotation member, a rotation knob, and an electric brush; the electrically connecting body has a side provided with a first locking hook and a second locking hook, and has a top provided with an electrically connecting plate extended through the passage of the first shell and having an electrically connecting terminal aligning with the slot of the first shell; the regulating module has a face provided with an inner conducting ring and an outer conducting ring, the outer conducting ring of the regulating module is provided with a carbon resistor; the first connecting member has a face formed with a contact arm and has a first side formed with a conducting end extended through the opening of the first shell and the first hole of the circuit board and electrically connected to the circuit board and a second side formed with a conducting plate electrically connected to the inner conducting ring of the regulating module; the second connecting member has a first side formed with a conducting end extended through the opening of the first shell and the second hole of the circuit board and electrically connected to the circuit board and a second side formed with a conducting plate electrically connected to the outer conducting ring of the regulating module; the pivot arm has a first end formed with a pivot hole pivotally mounted on the first locking hook of the electrically connecting body, a mediate portion provided with a resting rod and a second end provided with a contact end that is movable to contact the contact arm of the first connecting member to electrically connect the electrically connecting body with the first connecting member; the torsion spring is mounted on the first locking hook of the electrically connecting body and has a first end locked on the second locking hook of the electrically connecting body and rested on the resting rod of the pivot arm to pivot the pivot arm downward about the first locking hook of the electrically connecting body to move the contact end of the pivot arm toward the contact arm of the first connecting member; the rotation member has a first side provided with a rotation shaft extended through the through hole of the second shell and a second side provided with a push plate rested on a bottom of the pivot arm to pivot the pivot arm upward about the first locking hook of the electrically connecting body to detach the contact end of the pivot arm from the contact arm of the first connecting member; the rotation knob is secured to a distal end of the rotation shaft to rotate the rotation member; the electric brush is secured on the rotation member to rotate therewith and has two tail ends electrically connected to the inner conducting ring and the outer conducting ring of the regulating module respectively.
