A lamp, including an illuminant, a housing, and a shielding element, wherein the illuminant is situated in the housing, wherein the shielding element at least partially covers a first end area of the housing and protrudes from the first end area, characterized in that the shielding element has a first standing area that is directed away from the housing.

A lighting device capable of illuminating an entire region of a region to be illuminated with uniform brightness and with a desired color is provided. Provided is a lighting device that extends in a first direction and illuminates a region to be illuminated that extends in a second direction intersecting with the first direction includes a light source that emits coherent light, and a plurality of hologram components each of which diffracts the coherent light emitted by the light source to illuminate the entire region of the region to be illuminated. At least one of the plurality of hologram components diffracts the incident coherent light so that illuminance at both end portions in the second direction of the region to be illuminated is higher than the illuminance at the central portion.

A backlit three-dimensional lamp for a vehicle includes an indicia rendering disposed on a transparent lenticular sheet, an outer lens positioned in front of the transparent lenticular sheet, and a light source positioned behind the transparent lenticular sheet. The light source provides backlighting of the indicia rendering such that the lenticular sheet projects a forward image that hovers beyond the outer lens. A vehicle light assembly includes a light source adapted to produce a substantially homogeneous light, a rendering of indicia located adjacent the light source and facing away from the light source such that the rendering of indicia is backlit by the light source, and an array of light-modifying elements aligned with the light source to at least partially cover the rendering of indicia for creating a projection of the rendering of indicia outside the vehicle light assembly.

An LED lamp that can take the place of incandescent lamps. An elevated light source is positioned above a screw-type base. A first plurality of LEDs is connected in a series on one side of a flat substrate and a second plurality of LEDs, equal in number to the first, is connected in series on an opposite side of the substrate. Each LED of the first and second plurality of LEDs is mounted proximate a heat sink and a drive circuit is provided for the LEDs, with the drive circuit being located proximate and electrically connected to the screw base.

A lighting apparatus includes: a lamp body assembly, including a support base, a lampshade mounted on the support base, and a light-emitting body, a power supply module and a first connector that are connected to the support base, wherein the light-emitting body is electrically connected to the power supply module; a display assembly, including a carrier, a second connector connected to the carrier and facing the support base, and a display screen connected to the carrier, wherein the display screen is electrically connected to the power supply module; and a support assembly, connected to the first connector and the second connector.

A luminaire assembly and a silicone optical array. The luminaire assembly includes a housing, a substrate, and a silicone optical array. The housing defines a light emitting chamber. The substrate has a plurality of light emitting sources, such as light emitting diodes, supported thereby in an array. The substrate defines a peripheral edge. The silicone optical array has a plurality of silicone optics formed in the silicone optical array. The silicone optical array is located so as to cover one side of the substrate and the plurality of light emitting sources. The silicone optical array may further include a silicone mat and a plurality of silicone optics formed in the silicone mat and being arranged in an array corresponding to the array of light emitting sources.

A method and apparatus for a horticultural light for use in a horticultural facility is provided to minimize a dimension (e.g., height dimension) of the horticultural light. A sheet lens is adhered directly onto the printed circuit board and optionally the underlying metallic backing plate so as to environmentally seal the horticultural light. The sheet lens is comprised of polycarbonate and is pneumatically and/or thermally manipulated to include dome portions that are disposed in proximity to the respective one or more LEDs. Light generated by the LED is incident onto the inner surface of the respective dome portion at right angles through the entire beam angle. Accordingly, substantially none of the light is reflected back into the dome, but is rather propagated to an exterior of the light.

A light emitting arrangement (100) is provided for realizing anti-fouling of a surface (30) of a marine structure. The light emitting arrangement is shaped in sheet form and has an optical medium (4) and a light source (20) embedded in the optical medium and configured to emit anti-fouling light from an emission surface (301). The light emitting arrangement has at least one mirror configured to reflect anti-fouling light from the light source towards the emission surface. The mirror is arranged near or at the back surface and is electrically conductive and coupled to the light source for constituting a first electrode (120) arranged for transfer of electrical power between the light source and a power source. For example, the mirror forms a capacitor (6) in combination with an external electrically conductive element (50) and a dielectric layer (4a).
