A light source device includes: a light source having an upper surface including a light-emitting surface, the light source comprising a plurality of light-emitting parts arranged in a two-dimensional array; a lens located above and spaced apart from the light-emitting surface of the light source, wherein the lens comprises an optically functional part, and a flange part located along an outer periphery of the optically functional part; and a support part formed of a light-shielding material and configured to support at least the flange part of the lens. A surface area of a first surface of the optically functional part is greater than a surface area of a second surface of the optically functional part. The flange part defines at least one first recess in a surface located at a same side as the second surface.

Embodiments of the disclosure relate to retrofitting LED light bars into fluorescent tubular style lamp fixtures as well as integrating LED light bars into new lamp fixtures. In various embodiments a single light bar may be utilized with multiple style base ends to allow it to retrofit into a variety of existing fixtures. Some embodiments offer multiple mounting options on an LED light bar for existing lamp fixtures so that electrical utilities' rebate requirements can be met with a single LED light bar assembly.

An improved structure of a lighting display device includes a lower fixing element, an upper fixing element, a projection device, a transparent bottle, and an assembling element. The projection device is disposed inside the lower fixing element and the transparent bottle is disposed thereon and fixed by a positioning annulus on an inner surface of the lower fixing element. The assembling element has a depression surface atop to be engaged a positioning plate of the upper fixing element and an upper engaging space to mount on the transparent bottle. A spring is further disposed between the upper engaging space and the transparent bottle. Thereby the transparent bottle is able to display attractive visual effects by lighting projection and to be easily engaged and disengaged.

A self-expanding light shaping device for being separably mounted on a fastening arrangement of a lighting device is provided. The light shaping device features sidewalls of flexible material, which after the mounting on the lighting device surround a light shaping and light emitting region formed between an inlet opening and an outlet opening, tensioning elements designed for stabilizing the sidewalls and a fastening mechanism for separably mounting the light shaping device on the fastening arrangement of the lighting device, wherein the outlet opening is realized in the form of a round outlet opening, which is at least sectionally enclosed by a frontal tensioning element that expands the flexible material of the sidewalls.

Disclosed is light-emitting assembly comprising an elastic plate comprising: an elastic base and a plurality of connecting parts protrusively provided on the elastic plate, the plurality of connecting parts being spaced apart from each other; and a flexible light-emitting plate secured on a side of the connecting parts facing away from the elastic base, wherein portions of the flexible light-emitting plate located between adjacent connecting parts are arched toward a direction away from the elastic plate to form an arched portion when the elastic plate is in an un-deformed state, and the arched portions of the flexible light-emitting plate are flattened when the elastic plate is deformed by stretching. A method for manufacturing a light-emitting assembly is also disclosed. The light-emitting assembly is applicable to occasions in which the elastic deformation of the light-emitting assembly is required.

An optical device includes a clamp seat and a light tuning assembly. The clamp seat includes a base, a curved potion extending from the base, and a pressing portion extending from the curved portion. The light tuning assembly includes a support frame disposed at the base, an optical lens restrained by the support frame, and an adjusting member coordinating with the optical lens. In an application of the optical device, a user may clamp a multimedia mobile communication device by the base and the pressing portion to allow the optical lens to align with a light projecting assembly of the multimedia mobile communication device. The adjusting member is rotated to adjust a distance between the optical lens and the light projecting assembly. Light from the light projecting assembly is then focused or dispersed through the optical lens to solve an issue of unadjustable light of a conventional solution.
