An optical projection device for projecting a linear image is disclosed. Light emitted by an array of light emitting diodes arranged along an array axis is focused in at least a direction perpendicular to the array axis and diffused in a direction parallel to the array axis, thereby generating a linear image in which light from adjacent light emitting diodes is spatially overlapped. In some embodiments, the focusing and diffusion of the light is performed by a Fresnel lens and a lenticular lens, respectively. The optical projection device may be employed to virtually mark a surface, such as a floor in an industrial setting. High power light emitting diodes may be employed to generate a linear image having an illuminance of at least 4000 lux that is focused to a distance between 7.5 and 20 feet.

An LED lamp, in particular a table lamp, comprises a lighting head extending about a central axis; the head comprises: a body shaped as a ring about the axis and provided with a substantially annular seat; a plurality of LEDs arranged spaced apart from one another along the seat and about the axis and supported by a printed circuit board positioned in the seat and having a face, on which the LEDs are positioned, perpendicular to the axis; and a lens positioned in front of the LEDs to close the seat; the lens consists of a monolithic piece extending about the axis and has a concave annular inlet surface, facing the LEDs, and a convex annular outlet surface, substantially aligned parallel to the axis and extending about the axis and shaped so as to generate a rotosimmetric light emission about the axis.

A curving recessed lighting system having a plurality of pivoting, connectable channel sections, an LED strip (or more), and a flexible diffuser. Each housing section includes a base having connectable first and second ends, first and second flange members extending upward and outward therefrom and cut to both allow and limit pivoting between adjacent sections, and a U-shaped channel spaced from the flange members to create parallel channels. Flexible bands are secured within the parallel channels to isolate the LED strips within the U-shaped channel, as required. The flange members form two curved surfaces and the U-shaped channel in consecutive sections align to form a curved channel between the two curved surfaces. Preferably, the base portion of each of the plurality of housing sections has a depth not greater than ⅝ inches (0.625 inches). This allows flush placement in standard drywall without the need for notching studs.

A LED-based lighting assembly uses minimized distance between an LED source and a diffuser to reduce form factor size, and convex optics, elliptical diffusion and lateral recycling to produce from mini- or micro-chip LEDs a uniform geometrical shape for lit-pixel display of information at high definition. A less than one-to-one (1:1) ratio of LED chip distance and vertical distance between chip and diffuser is achieved with desired uniformity of lit-pixel displays. Reduced distance between diffuser and LEDs and an improved optic provide for more dense yet compact configuration of LEDs in lighting components of automobile grilles and emblems and other lit branding or safety devices in commercial and residential applications.

A backup light apparatus provides a somewhat uniform distribution of light intensity in an area within the view of a backup camera of a vehicle. The backup light apparatus may satisfy various governmental and manufacturer safety rules. The backup light apparatus has a pillow lens array, a first collimator, a prism lens array, and a second collimator. The first collimator directs light in the direction of its optical axis to the pillow lens array. The second collimator directs light in the direction of its optical axis to the prism lens array. The pillow lens array has an array of pillow lenses facing away from the first collimator. The prism lens array has an array of prism lenses facing away from the second collimator. The prism lenses direct light at varying angles relative to the optical axis of the second collimator.
