Various embodiments may relate to an optical unit for a light-emitting structure, a light-emitting structure, and a light box comprising the light-emitting structure. The optical unit includes a body and a light-blocking structure, wherein the body includes at least one reflective surface, wherein the light-blocking structure includes a first light-blocking structure and a second light-blocking structure, wherein the first light-blocking structure is formed in one piece with the body, and the second light-blocking structure is arranged in the first light-blocking structure, wherein the first light-blocking structure is arranged to at least partially surround the reflective surface, to block the light leaks from the reflective surface by the second light-blocking structure.

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.

Provided are foldable light softboxes for users to conveniently carry around. The softbox comprises a body portion, a set of flexible and foldable frames, means for switching the softbox between an unfolded state and a collapsed state, and means for fitting the softbox over light sources of different sizes. The body portion of the softbox comprises a front panel, a back panel and a strip of material that circumferentially attached to the front panel to the back panel. The flexible and foldable frames are attached along the circumferences of the front and back panels. The softbox can be folded to fit in a circular container, for example, a bag.

Lighting device (22) for a false ceiling (10) comprising a plurality of T-profiles (14) having respective longitudinal axes (A) and arranged in a square mesh grid (12), in which each T-profile (14) has a lower wall with a width (W) and in which the grid (12) has a center distance (D) between the longitudinal axes (A) of T-profiles (14) parallel and adjacent to one another, in which the lighting device (22) has an elongated parallelepiped shape with a width (W′) comparable to the width (W) of said T-profiles (14), a height (h) of less than 15 mm and a length (D′) comparable to said center distance (D) between the longitudinal axes (A) of T-profiles (14) parallel and adjacent to one another, and in which said lighting device (22) is capable of being fitted directly in contact with the lower wall of a respective T-profile (14).

Provided is a modular light fixture. The device includes a light shroud, a light fixture base having a first cylindrical housing, a second cylindrical housing, a quick disconnect with a pair of external pins, and a light fixture base supporting attachment that includes a pair of P-shaped channels. The shroud attaches to the first cylindrical housing, and the base attachment attaches to the base via the P-shaped channels and the first and second external pins. The shroud and base attachments can be interchanged as desired for use as a hanging light, an up light, a down light, a well light, a path light, a wash light, or any combination thereof. The device allows for quick and easy conversion of lights from one style to another without requiring an entirely new fixture, enables simple repairs, and lessens the number of items required to be stocked by an installer.
