According to one embodiment, an illumination system includes a plurality of white light sources that satisfies −0.2≦[(P(λ)×V(λ))/(P(λmax1)×V(λmax1))−(B(λ)×V(λ))/(B(λmax2)×V(λmax2))]≦+0.2 where P(λ) is an emission spectrum of a white light source having a specific color temperature, B(λ) is an emission spectrum of black body radiation having a corresponding color temperature, V(λ) is a spectrum of spectral luminous efficiency, λmax1 is a wavelength at which P(λ)×V(λ) becomes maximum, and λmax2 is a wavelength at which B(λ)×V(λ) becomes maximum. The respective white light sources have different color temperatures, and light from the respective white light sources is irradiated from different directions to a target.

A presentation system for a celebration of an individual comprising: a frame; a lighting system disposed along an inner edge of a perimeter of the frame; a fabric removably attached to the frame disposed outwardly from the lighting system adapted to be illuminated by the lighting system; an image included on the fabric associated with aspects of a subject of the celebration of the individual; and, a memorial container disposed in front of the fabric wherein the image and the memorial container cooperate to form a composite image when viewed by an audience.

According to one embodiment, an illumination system includes a plurality of white light sources that satisfies ?0.2?[(P(?)?V(?))/(P(? max 1)?V(? max 1))?(B(?)?V(?))/(B(? max 2)?V(? max 2))]?+0.2 where P(?) is an emission spectrum of a white light source having a specific color temperature, B(?) is an emission spectrum of black body radiation having a corresponding color temperature, V(?) is a spectrum of spectral luminous efficiency, ? max 1 is a wavelength at which P(?)?V(?) becomes maximum, and ? max 2 is a wavelength at which B(?)?V(?) becomes maximum. The respective white light sources have different color temperatures, and light from the respective white light sources is irradiated from different directions to a target.

A back lit artwork frame provides an illuminated frame for hanging an item of artwork. The frame includes a channel that receives a plurality of LED lights and a diffuser that directs light emitted by the LEDs to the lateral sides of the frame. In some embodiments the light is directed towards a wall surface. In other embodiments the light is reflected outwardly from the wall. The backlit frame includes a controller which may regulate the intensity, color, pulse and other behaviors of the lighting. The LED lighting may also operate in response to an audio input. The controller may communicate with an app on a mobile device.

Display units for lithophanes and methods for manufacturing them. A display unit may include a pane, or a stand piece, formed of a clear or translucent material of construction. At least a portion of a frontward-facing surface of the pane or the stand piece may include a roughened surface formed thereon. The display unit may include at least one light source positioned sufficiently proximate to, or in contact with, one or more edges of the pane or the stand piece to direct light from the at least one light source as at least one light path into and through the clear or translucent material of construction toward the roughened surface. The display unit may include means for positioning a lithophane upon, or proximate, to the roughened surface. Users of such display units may experience greater lithophane viewing convenience using either natural light or with the at least one light source.
