Conductive mounting structures for lighting lamps

A lighting lamp comprising:

• a first assembly connected to a power supply, the first assembly including a first mounting member and a first contact;
• and
• a second assembly including a light source, a second mounting member, and a first conductive component, wherein the first mounting member and the second mounting member are configured to slidably engage with one another when the second assembly is rotated with respect to the first assembly to mount the second assembly to the first assembly;
• wherein the first conductive component is disposed on the second assembly such that when the first assembly and the second assembly are mounted to one another, the first contact is in contact with the first conductive component, thereby electrically connecting the power supply to the light source;
• wherein the second mounting member defines a first circle when the second assembly rotates with respect to the first assembly, wherein the first contact is disposed at the center of the first circle.
