Abstract: Disclosed are an elastic assembly and a down lamp. The down lamp includes a lamp body and an elastic assembly. The elastic assembly includes a limiting assembly and a spring. The limiting assembly is provided with a rotating cavity. The fixing end of the spring is rotatably embedded in the rotating cavity, so that a flip angle of a movable end of the spring ranges from 0° to 90°. The present disclosure can enlarge the adjustable angle of the spring and reduce the assembly difficulty of the down lamp.

Abstract: Disclosed is a night downlight, including a plastic case, a first lamp bead, a second lamp bead and a light guide ring. One end of the plastic case is provided with a light outlet, and the bottom of the plastic case is provided with the first lamp bead and the second lamp bead, the first lamp bead is arranged at the center of the bottom of the plastic case, the light guide ring includes a light guide inner ring and a light guide surface ring, the light guide inner ring is sleeved in the plastic case, one end of the light guide inner ring abuts against the second lamp bead, and the light guide surface ring is connected with the light guide inner ring and protrudes from the light outlet. The light guide area of the night downlight is larger, which can meet the needs of night lighting.

Abstract: Disclosed is a night downlight, including a plastic housing, a light source plate, a reflective cup, and a light guide sleeve. The plastic housing is provided with an opening, and the light source plate is arranged on an inner side of the plastic housing opposite to the opening. The light source plate is provided with a first light source and a second light source. One end of the reflective cup abuts against the light source plate. The light guide sleeve is arranged between the other end of the reflective cup and the plastic housing. The light guide sleeve is in snap-fit with the reflective cup. The snap-fit design of the light guide sleeve and the reflective cup allows replacement of the small component rather than replacement of the whole face ring when the snap-fit structure fails, thereby effectively reducing waste in repair and replacement.
