A directivity backlight display device with reflector curvature assisted diffuser includes a light source module, a reflective narrow-angle diffuser, a concave reflector, and a backlit type display panel. The light source module projects a light. The reflective narrow-angle diffuser includes a concave surface or a flat surface served as a reflecting surface. The reflecting surface is provided with a plurality of micro curved mirrors laid out in an array. The light is reflected and diffused by the reflective narrow-angle diffuser and the concave reflector to provide a uniform directional light beam. A backlit type display panel is deployed to display an image. The uniform directional light beam penetrates the backlit type display panel to provide a directional image light beam, and then projects the directional image light beam to a projection area. With this arrangement, a reflective narrow-angle diffuser with a low concave curvature is deployed to achieve a high-directivity image projection.

The present invention relates to lighting fixtures which are mounted into architectural finished surfaces such as ceilings, walls and floors, and is applicable to new installations as well as the renovation of existing surface-mounted fixtures. One embodiment relates to a modular lighting device for retro-fitting to an existing lamp housing which is flush mounted or countersunk into an opening of a ceiling or interior surface of a building, the modular lighting device comprising a lamp-fitting configured for receiving a light source and configured for attachment to the existing lamp housing, and reflector for reflecting and/or modifying light from the light source, the reflector comprising a narrow top section configured for attachment to said lamp-fitting, and a wider bottom section for covering said opening.

A lighting lamp is provided. The lighting lamp includes a light module and a lens. The lens includes a lens body, provided with a first end and a second end which are opposite to each other and a side wall located between the first end and the second end, in which a light source of the lighting lamp is arranged at the first end, and at least a portion of the side wall is configured as a light emitting component. The lens also includes a light incident component, arranged at the first end of the lens body, in which the light incident component irradiates light emitted by the light source to the second end. The lens includes a light reflecting component, arranged at the second end of the lens body.

A lighting system for providing uniform bright lighting of products within in a glass door refrigerated cabinet. The lighting system has a frame member with an angled wing extending therefrom that wraps around a side edge of a light-transmitting optical shield, and a LED lighting strip positioned between the frame member and the optical shield. The LED lighting strip has a plurality of spaced-apart LED lights mounted therealong with a coined reflective facet optic mounted around each LED light. The angled wing(s) reflects light emitted laterally outwards from the at least one LED lighting strip such that the light can be re-directed to evenly illuminate products in a refrigerated cabinet. The angled wing(s) also protects a user's fingers from cracking the plastic optical shield which can become brittle in the cool or cold temperatures of the refrigerated cabinet.

A trim member for a lighting device module includes an annular body having a first end portion that is connectable to a housing of the lighting device module and has a light receiving opening, and a second end portion opposite to the first end portion. The second end portion has a light emitting opening and is configured to be positioned outside of the housing of the lighting device module. A first curved or tapered surface extends from the light receiving opening toward the light emitting opening, and has a diameter that increases toward the light receiving opening. A second curved or tapered surface extends from the first curved or tapered surface to the light emitting opening, and has a diameter that increases toward the light emitting opening.
