Abstract
A light bulb is disclosed, and includes a screw shell defining a cavity, a screw shell insulator, and a driver board. The screw shell insulator defines a passageway that terminates in an aperture. The driver board includes a positive leg that projects from a proximal edge of the driver board, with a proximal end portion that protrudes outside of the aperture, and a negative leg that projects from the proximal edge of the driver board, with a proximal end portion that is electrically connected to the screw shell. The positive leg is configured to extend through the passageway to make electrical contact with a positive terminal of a light socket. Variants in which a base shell and the legs are configured for bayonet type, multifaceted reflector, and T8-like bases are also disclosed.
Claims15
A light bulb, comprising:
- a screw shell defining a cavity;
- a screw shell insulator located within the cavity, wherein the screw shell insulator defines a passageway that terminates in an aperture;
- a driver board including a positive leg that projects from a proximal edge of the driver board, wherein the positive leg defines a proximal end portion that protrudes outside of the aperture of the screw shell insulator, and a negative leg that projects from the proximal edge of the driver board, wherein the negative leg defines a proximal end portion that is electrically connected to the screw shell;
- wherein the positive leg is configured to extend through the passageway to make electrical contact with a positive terminal of a light socket.
A light bulb, comprising:
- a base shell defining a cavity;
- a base shell insulator located within the cavity, wherein the base shell insulator defines at least one passageway that terminates in an aperture;
- a driver board including a positive leg that projects from a proximal edge of the driver board, wherein the positive leg defines an proximal end portion that protrudes outside of the aperture of the base shell insulator, and a negative leg that projects from the proximal edge of the driver board, wherein the negative leg defines a proximal end portion that is electrically connected to the base shell or that protrudes outside of another aperture of a second passageway of the base shell insulator;
- wherein at least the positive leg is configured to extend through the at least one passageway to make electrical contact with a positive terminal of a light socket.
