Abstract: A light guide element (100) includes a light guide plate (20) and a frame (23). The light guide plate includes a first guiding portion (21), and a second guiding portion (22) adjoining the first guiding portion. The first guiding portion has a first light-emitting surface (211), a first back surface (212) opposite to the first light-emitting surface, and a light incident surface (210) connecting the first light-emitting surface and the first back surface. The second guiding portion has a second light-emitting surface (221) and a second back surface (222) opposite to the second light-emitting surface. A connecting portion (24) connecting the two guiding portions faces the light incident surface. The frame is integrated with the first guiding portion of the light guide plate.

Abstract: A light source having a light pipe and a light generation section. The light pipe includes a two-dimensional sheet of transparent material having a transparent top surface that is substantially parallel to a reflective bottom surface. The light pipe includes light pipe scattering centers that cause light traveling in the sheet of transparent material to be scattered in directions that allow some of the scattered light to escape the sheet through the top surface. The light generating section includes a plurality of LEDs and a mixing chamber. The LEDs are positioned to emit light into the mixing chamber. The mixing chamber includes an adapter having a wedge-shaped cavity with reflective walls. The cavity has an opening positioned to direct light into the light pipe. The mixing chamber includes scattering centers for redirecting light traveling in the cavity in directions that would not be obtained by reflection from the reflective walls.

Abstract: A structure for double-sided light box, comprising a frame having a plurality of wiring ducts disposed on its inner surface for placing electric wires, said frame having two trenches correspondingly disposed on an outer rim of said frame, an upper and a lower lid pivotally connected to said trench with a plurality of spring blades disposed among said upper and said lower lid and said frame to fixedly hold said upper and said lower lid to said frame by means of a elastic force of the spring blades; a recess being disposed at a inner rim for holding surrounding edges of a lighting component and a double-sided backlight module; said backlight module having its upper and lower surface attached to one advertising panel respectively, with said upper and said lower lid clasping fixedly advertising panels and said backlight module; when said lighting component generating a first light source, said first light source projecting light on said backlight module to let said upper and lower surface of said backlight module

Abstract: An optical dispersion system comprising a light source where light is directed to be illuminated from the system, a prismatic magnifier to expand a coverage area of the light illuminated from the light source and to deflect and magnify the light, and a removable front panel having a cutout area through which the light source illuminates.

Abstract: A light emitting panel having first and second panels that are constructed of a generally transparent material and that are connected such that the second panel is angularly positioned relative to the first panel. The first panel has first and second opposing surface, wherein at least a portion of the surfaces have a reflective material disposed thereon and an aperture through the reflective material is positioned on the first surface. A light source is associated with the second panel and a contact-less switch sensor is positioned at the second surface.

Abstract: Light emitting panel assemblies include one or more light emitting panel members each having at least one pattern of optical deformities that may be varied in size, shape, density, placement, angle, rotation and/or type to obtain at least one light output distribution having a form or shape of at least one of text, graphics, logo or image. At least some of the optical deformities may be shaped or oriented preferentially to cause different colored light propagating through the panel member in different directions to create a multi-colored light output distribution. Also, a plurality of panel members each having a different light output distribution may be placed in overlying relation to one another to produce a composite output distribution when viewed through the panel members or a display overlying the panel members.

Abstract: An apparatus and a method for producing an animation effect are disclosed. The apparatus comprises at least one light reflecting member, a first light source, a second light source, and means to intermittently activate the first and second light sources to produce an animation effect.

Abstract: An image display unit 10 comprises a light source 14 and a light diffusing panel 18, over which is mounted an opposed pair or retaining sheets 20 with a volume 22 formed between each retaining sheet 20 and the panel 18 for receiving an image-bearing sheet 34. An elongate opening 26, 28 for providing access to the volume 22 formed in each face of the unit 10 is located spaced from the edges of the unit 10, so allowing a user to access the volumes 22 regardless of proximity of the edges of the unit 10 to other units, or to a wall or the like.

Abstract: A lighting apparatus (10) includes a wave guide (14) formed from a translucent material. The wave guide has a top surface (30), a bottom surface (32) that has a pre-defined curvature, and at least one side surface (34) that receives light (40) injected therein. A plurality of microstructures (36) is arranged on selected areas of the bottom surface (32) of the wave guide (14). The plurality of microstructures (36) cooperates with the pre-defined curvature of the bottom surface (32) to scatter at least a portion of the light (40) injected into the at least one side surface (34). The scattered light (42) exits the wave guide (14) through the top surface (30). At least one light emitting diode (16) injects light (40) into the at least one side surface (34) of the wave guide (14). The scattered light (42) that exits the wave guide (14) forms at least one symbol viewable by an associated observer.
