Abstract
A sealing ring, a light sensation controller and an LED street lamp. The sealing ring comprises a sealing ring body (41). The sealing ring body (41) comprises an upper end face and a lower end face which are opposite each other, and is provided with a mounting hole (40) penetrating the upper end face and the lower end face. At least two annular waterproof skirts (42) are arranged on the peripheral wall of the sealing ring body (41), the at least two annular waterproof skirts (42) are arranged at intervals in the axial direction, and the outer diameters of the at least two annular waterproof skirts (42) are sequentially increased or sequentially reduced in the axial direction. The light sensation controller comprises a light-operated device (2), a light-operated socket (3) and the sealing ring. The light-operated socket (3) is sleeved in the mounting hole (40) of the sealing ring body (41), and the lower end of the light-operated socket (3) extends out of the lower end face of the sealing ring body (41); and the light-operated device (2) is sleeved on the waterproof skirts (42) of the sealing ring body (41), and seals the upper end face of the sealing ring body (41). The LED street lamp comprises a lamp body (1) and the light sensation controller mounted on the lamp body (1).
