A lamp fixing device comprises a fixing base (1) and a connecting base (2). The fixing base (1) is provided with a first electrical connecting part. The connecting base (2) has a second electrical connecting part. The first electrical connecting part comprises a first accommodating groove (41), a second accommodating groove (42) and a third accommodating groove (43) that are concentrically arranged, and comprises an L electrode (91), a grounding electrode (92) and an N electrode (93) that are respectively accommodated in the first, second and third accommodating grooves. The second electrical connecting part comprises a first conductive terminal (61), a second conductive terminal (63) and a third conductive terminal (62) that are concentrically distributed. The first conductive terminal (61), the second conductive terminal (63) and the third conductive terminal (62) are respectively accommodated in the first accommodating groove (41), the second accommodating groove (42) and the third accommodating groove (43), and are electrically connected to the L electrode (91), the grounding electrode (92) and the N electrode (93) respectively. The present invention enables an operator to rapidly install and detach a lamp, and is easy to use and convenient to maintain. |
