The invention discloses an electrodeless rotary lamp holder which comprises a lamp holder shell. A joint; a contact pin fixing plate; the number of the conductive contact pins is at least two, the conductive contact pins are fixed on the contact pin fixing plate, and the distances between the conductive contact pins and the rotating axis of the connector are different; the conductive needle disc is arranged below the contact needle fixing plate and fixedly connected with the connector, at least two annular conductive rings arranged at intervals are arranged on the conductive needle disc, the conductive rings take the rotating axis of the connector as the circle center, and the conductive rings and the conductive contact needles are arranged in a one-to-one correspondence mode; when the connector rotates relative to the lamp holder shell, the conductive needle disc rotates relative to the conductive contact needles along with the connector, and each conductive contact needle is in electric contact with the cor
