A system for growing a plant includes an inwardly reflective enclosure and preferably a top. A plurality of LEDs, preferably controlled by a control unit, selectively emit light onto predetermined portions of the plant. The control unit controls the growing conditions inside the enclosure with the use of air vents and air flow, an optional heater, and feedback from light intensity and color sensors. The inwardly reflective enclosure can be formed of inner and outer walls with a reflective film sandwiched in between. If desired, a recycling collar can be used with any of the LEDs to increase the intensity of the light ray. The top cover can be formed of a plurality of panels rotatable about their longitudinal axis between a closed position and open position. In another embodiment, pair of inwardly reflective enclosures share a common, reflective wall with holes. The two enclosures are operated through light and dark cycles so as to exchange oxygen and carbon dioxide alternately with one another

A method for retrofitting a billboard system illuminated by an arc lamp which includes a reflector with reflector features and an output lens includes the steps of removing the lens from the arc lamp housing, mapping the light pattern output of the arc lamp, and then removing the arc lamp and reflector from the housing. Next, a plurality of LEDs is mounted on an LED circuit board in a pattern so that light output by the LEDs replicates the light pattern of the arc lamp, including the reflected light. The circuit board is then installed inside the housing, and the lens is reattached. Preferably, the LEDs include a central LED cluster of densely packed LEDs to replicate the original output of the arc and a pair of LED groups of less densely packed LEDs, located on either side of the LED cluster, to replicate the output from the reflector. If desired, some of the LEDs may be oriented at an angle relative to the circuit board to help replicate more precisely the original output of the arc lamp which may include light that is reflected by interior surfaces of the arc lamp housing and not directly emitted from the arc or reflector.

An LCD monitor comprises an LCD panel and a backlight for providing illumination to the LCD panel. The backlight includes a light box having a reflective bottom and sides and an open top for allowing light to flow outwardly toward the LCD panel. The light box includes a light source preferably comprising a plurality of LED elements for generating light either from said edge or from said bottom, or from both said bottom and said edge. The light box further preferably comprises a plurality of wave plates interspersed with the LED elements for intercepting light and changing the polarity of such intercepted light. Preferably, the backlight includes a polarizer for transmitting light from the light box of a first polarization towards the LCD panel and reflecting light of a second polarization back towards the light box. At least some of the reflected light of the second polarization passes through the wave plates, is converted to the first polarization, and is reflected back towards said polarizer. Thus, the wave plates act as secondary light sources and assist in producing a uniform light output.

An illumination system comprises an arc lamp having a cathode and an anode which emit light from a hot spot. A dual paraboloid retroreflector comprising upper and lower halves intercept light emitted rearwardly from the arc lamp and reflects the intercepted light back towards the hot spot. The retroreflector is spaced from the hot spot at a distance such that light rays emitted from the hot spot which are incident on the upper or lower half are redirected to a corresponding surface of the other half and reflected back to the hot spot. The system may further include a main dual paraboloid reflector for redirecting output light from the arc lamp and retroreflector. Light emitted from the arc lamp is intercepted by a first half paraboloid reflector and collimated to be redirected toward to a corresponding surface of a second half paraboloid reflector member, so as to be reflected in a direction opposite to the arc lamp output. The system may include a pair of ellipsoid reflectors, one of which intercepts the arc lamp output and directs the light onto a corresponding surface of the other ellipsoid reflector, which change the output direction of the light to be parallel to the arc lamp output.

A projector includes a laser for forming blue or UV light and a rotatable color wheel having at least one sector coated with a phosphor for converting such blue or UV light into green light. The projector further includes a source of red light and a source of blue light which, in certain embodiments, is the color wheel. At least one imaging device is positioned to receive, directly or indirectly, the green, red and blue light for forming a green, red, and blue portions of an image to be projected. The projector further has projection optics for receiving the green, red, and blue portions for projecting the image. The projection optics may receive sequential green, red, and blue portions of the image to be projected or the green, red, and blue portions can be formed by separate light sources and combined into the final image and projected.

A lamp system comprises a light source and a parabolic reflecting collar positioned around the light source and having an aperture through which a center axis extends. The aperture permits light rays emitted by the light source at low angles relative to the axis to be emitted from the parabolic reflecting collar, while light rays emitted by said light source at higher angles are reflected by the collar for recycling. The parabolic reflecting collar is positioned such that higher angle light rays are reflected twice, off opposing wall reflecting portions, back to their point of origin. Preferably the light source is an array of multiple LEDs having different colors and sizes.

A billboard or other large display for displaying information has a billboard frame, an artwork layer, and either a plurality of columns of LED light plates or vertical strips of LED lights. The LED plates are small backlight panels formed in an array covering large areas suitable for standard billboards. The LED plates are secured to one another to hang from the billboard frame in separate columns. The columns are situated between the artwork layer and the billboard frame to provide a backlight for the artwork layer. The artwork layer can include two or more layers such that different artwork is displayed depending on the ambient lighting conditions as well as the backlight operation. The LEDs are preferably controlled by a controller to provide desired backlight conditions as well as to display content.

A lighting device includes an LED light source for emitting light in a first direction about an axis, a projection lens mounted on the axis, and a gobo having a preselected design which is mountable along the axis between the LED light source and lens to intercept at least some of the emitted light. The lens is moveable along the axis, preferably positionable at least at three axial positions. The first such axial position is the distance from the LED light source corresponding to the focal point of the lens. The second axial position is the distance from the gobo corresponding to the focal point of the lens. The third axial position is a distance from the LED light source corresponding to less than the focal point of the lens. In one embodiment, the lighting device includes a recycling collar having a central opening through which the axis extends. In another embodiment, the projection lens is a TIR lens.

An aerial projection display project an image of an object to a remote location for viewing. The display includes a pair of spherical, parabolic, or elliptical reflectors positioned and oriented relative to one another such that, when the object is placed at one or more predetermined locations, an image of such object is transmitted to the first reflector of said pair, reflected by said first reflector to the second reflector, and refocused by the second reflector as an undistorted 3-D image. In a second embodiment, the reflectors are paraboloid reflectors sharing a common axis of revolution. In another embodiment, the reflectors are elliptical reflectors each having a pair of foci. The foci lie along a common axis, and one of said foci is common to both reflectors. In a third embodiment, the reflectors are spherical reflectors The first reflector reflects a distorted image of the object to the second reflector, which corrects the distorted image from said first reflector to project a substantially undistorted image of the object.
