Tree lamp

A tree lamp, comprising:

• a lamp housing, wherein the lamp housing is configured to have a tree shape, a mounting portion is formed at a lower end of the lamp housing, and the lower end of the lamp housing is further provided with power connection contacts, wherein the mounting portion is in a circular shape;
• a light-emitting body, wherein the light-emitting body is provided on the lamp housing, and the light-emitting body is electrically connected to the power connection contacts;
• and
• a base, wherein a power supply unit is provided inside the base, a mounting recess is formed in a top surface of the base, electrically-conductive structures are provided inside the mounting recess, and the electrically-conductive structures are electrically connected to the power supply unit, wherein the mounting recess is in a circular shape;
• and
• wherein the lamp housing comprises a housing body, the mounting portion is provided at a lower end of the housing body, and the power connection contacts are provided in an inner cavity of the mounting portion;
• and
• each of the power connection contacts comprises contact pins and an elastic member, one end of each of the contact pins is exposed out of the mounting portion, two opposite ends of the elastic member are respectively connected to the contact pins and the mounting portion, and when the mounting portion is mounted in the mounting recess, the mounting portion is capable of rotating relative to the mounting recess, the power connection contacts are in contact with the electrically-conductive structures, and elastic members are compressed;
• wherein there are two contact pins, one of the two contact pins is located at the center of the mounting portion, and the other one deviates from the center of the mounting portion;
• and
• each of the electrically-conductive structures comprises a first electrically-conductive sheet and a second electrically-conductive sheet, the first electrically-conductive sheet and the second electrically-conductive sheet are configured to be in contact with the different contact pins, the first electrically-conductive sheet is a round electrically-conductive sheet, the second electrically-conductive sheet is an annular electrically-conductive sheet and surrounds the first electrically-conductive sheet, and there is a gap between the first electrically-conductive sheet and the second electrically-conductive sheet.
