A deck system can include a first deck board; a second deck board; an accent strip; and/or a deck clip. In some embodiments, the first deck board and the second deck board are slotted to receive the deck clip. In some embodiments, the deck clip has a hole configured to receive a screw to attach the deck clip to a wall. In some embodiments, the accent strip is made of aluminum and/or vinyl. A deck anchor system can include a deck anchor, a bungee cord, a rope, and/or a corresponding hook. In some embodiments, the deck anchor includes a tightening handle; a blade; an eye hook; a shaft, a pinch bar; and/or a cam lever. In some embodiments, the shaft is threaded. In some embodiments, the pinch bar is curved. In some embodiments, an end of pinch bar is covered in rubber.

A stage light with a lens buffering feature includes a light source emitting light along an optical path and a dimming lens provided on the optical path. The dimming lens is mounted on a mounting plate and moves freely along the optical path under the driving of a drive mechanism. A limit plate is provided on at least one side of the dimming lens along the direction of the optical path, and the limit plate is provided with a first buffering magnet thereon. The mounting plate is provided with a second buffering magnet corresponding to the first buffering magnet, and the polarities of the sides of the first buffering magnet and the second buffering magnet close to each other are the same. When the stage light is suddenly powered off or during transportation, the dimming lens or the mounting plate can avoid collision with other components.

In a light source device, an axis extends from a light-emitting face and perpendicularly to the light-emitting face. A reflective surface includes a curved surface defined by rotating a first arc which is a part of an ellipse around the axis. The ellipse has a first focal point and a second focal point which are located on the light-emitting face. The second focal point is located adjacently to the first arc with respect to a center of the ellipse. A distance from the first focal point to the axis is shorter than a distance from the second focal point to the axis.

A lens diffusing light emitted from a light source includes a concave light-incident surface, a light guide portion, and a light-emitting surface. The light-incident surface includes a plane portion opposed to the light source and an optical function portion that is formed on the plane portion and one of scatters and diffuses the light. The light emitted from the light source enters the light-incident surface. The light that has entered the light-incident surface passes through the light guide portion. The light-emitting surface emits the light passed through the light guide portion.
