An optical system includes a plurality of lenses and a lens holding member. Each of the plurality of lenses has a cut-off face to have a shape of a partial circle formed by cutting off part of a periphery of a first circle. Cut-off faces of adjacent lenses face each other. The adjacent lenses have an interval between centers of the lenses is smaller than a diameter of the first circle. The lens holding member has an outer surface including a plurality of lens arrangement holes in which the plurality of lenses are respectively disposed. Adjacent lens arrangement holes are linked together to form a linked hole. The linked hole has a shape that represents part of a shape formed by disposing a plurality of second circles, the second circles being partially overlapped, each of the second circles having a diameter larger than a diameter of the first circle.

The present disclosure relates to an assembly component, a lamp and a method of manufacturing an assembly component. The assembly component includes a first element and a second element, the first element includes a first main body and a first elastic engaging portion which are connected to each other; the second element includes a second main body and a second engaging portion; the second main body has a moving space; a bottom wall of the moving space forms a clamping surface, the second engaging portion is connected to a side wall of the moving space, the first elastic engaging portion is clamped between the second engaging portion and the clamping surface, and the clamping surface limits the first elastic engaging portion in an outward direction.

An installation assembly of a ceiling lighting fixture, a ceiling lighting fixture and a ceiling lamp are provided. The installation assembly includes a fixing base and a connecting base detachably connected with the fixing base. One of the fixing base and the connecting base is provided with a snap recess, and the other of the fixing base and the connecting base is provided with an elastic buckle which is capable of being snap-fitted with the snap recess. The elastic buckle has a guide slope, the elastic buckle is capable of being compressed as the connecting base moves toward the fixing base, and being introduced into the snap recess through the guide slope. The elastic buckle is rotationally fitted with the snap recess, and the snap recess is provided with an avoidance notch for the elastic buckle to be detached.

A retainer ring for a light fixture includes a cylindrical main body section that defines a cylindrical axis, and an inner retaining flange that extends radially inward from a distal end of the main body section. The inner retaining flange extends substantially about a circumference of the distal end. One or more coupling features extend radially inward from the retainer ring. A customization kit for a light engine that defines an optical axis includes a retainer ring configured to couple with the light engine, and two or more primary optics that are mechanically compatible with the light engine, and retainable to the light engine with the retainer ring. When the retainer ring couples with the light engine, a cylindrical axis of the retainer ring coincides with the optical axis.

A panel light fixture includes: a light source assembly; a heat sink attached to the light source assembly; an adaptor ring arranged to accommodate the light source assembly and the heat sink; an anchor plate, having a connection hole and a plurality of mounting holes, for mounting with a junction box; and a contact spring firmly connected to the heat sink for anchoring the anchor plate through the connection hole. The junction box is mounted to the anchor plate through the plurality of mounting holes.

There is provided a multipurpose bracket including a horizontal portion, a right vertical portion, and a left vertical portion. The horizontal portion has a hook on a front surface of the horizontal portion, and a downward protrusion at a lower edge of the horizontal portion. The right vertical portion is connected at a right end of the horizontal portion, and has a right-upper protrusion and a right-lower protrusion. The left vertical portion is connected at a left end of the horizontal portion, and has a left-upper protrusion and a left-lower protrusion.

Methods and apparatus are presented for retaining a dome lens in a lighting element that provides a projection of light forming a substantially uniform bright light on a surface a known distance from the lighting element. The lighting element includes a dome lens that is removably positioned proximal to a light source, such that the light source is retained at a location within a focal length of a projection lens and at or within a focal length of the dome lens. The dome lens magnifies the light outputted by the light source, such that the projected light is brighter than the light generated by the light source.
