A lamp capable of expanding illumination range includes a lighting and cooling module, a reflective cup, a lampshade, a diffuser plate and a wash wall cup. The reflective cup and lampshade are connected to the lighting and cooling module; the lampshade surrounds the reflective cup; the diffuser plate is divided into an oblique circular arc plate and a riser; the circular arc plate has rule gratings formed by convex and concave embossed marks. A front arc wall is built on a side of the wash wall cup, and a rear arc wall is built on the other side. An inlay seam is formed between the front and rear arc walls; the circular arc plate is mounted onto the front arc wall; edges of the riser are plugged into the inlay seam; and the wash wall cup is plugged from the bottom of the lampshade to form the lamp.

Apparatus and associated methods relate to providing an optical display apparatus that can be used to make a light source display variable apparent sizes in response to light intensities emitted by the light source. In an illustrative example, the optical display apparatus may have a first baffle arranged on the top of a light source. The optical display apparatus may also include a second baffle, the first baffle may be nested in the second baffle such that a first intensity of a first beam of light guided within the first baffle is stronger than a second intensity of the second beam of light guided between the first baffle and the second baffle. By adjusting the light intensities, different display regions of a translucent diffuser may be lit, which may provide controllable apparent sizes of a light structure.

A lighting device contains light-emitting elements and has an elongated shape. The lighting device has a housing that has reflective side walls extending in a longitudinal direction of the housing; a cavity formed between the reflective side walls; and light-emitting elements arranged at least partially along the longitudinal direction relative to each other in the cavity. An opening of the cavity forms a light-emitting area, A width of the cavity expands from the light-emitting elements towards the opening at least in sections. A reflective element covers at least a section of the opening and reflects a part of light emitted from the light-emitting elements towards the cavity and reduces a width of the light-emitting area compared to a width of the opening.

An illumination system converting light beams into wide-angle light transmissions including i) a cylindrical member having a cone-shaped depression in a distal end; and ii) a semi-circular member having an inner radial surface adjacent to a sidewall of the cylindrical member; and angled upper and lower annular surfaces extending from the cylindrical member and meeting at an outer radial edge. A light beam entering the proximal end of the cylindrical member strikes a first edge of the cone-shaped depression and is reflected out as a first light transmission; or it strikes a second edge of the cone-shaped depression, is reflected against the upper and lower annular surfaces, and exits the cylindrical member as a second light transmission parallel to the first diffused light transmission. At least one light path passes through a diffuser on the cylindrical member.
