In times of insufficient sun light, an artificial lighting device activates the luminosity.

Abstract: A system provides light of selectable spectral characteristic (e.g. a selectable color combination of light), for luminous applications such as signage and indicator lights. An optical integrating cavity combines energy of different wavelengths from different sources, typically different-color LEDs. The cavity has a diffusely reflective interior surface and an aperture for allowing emission of combined light. Control of the intensity of emission of the sources sets the amount of each wavelength of light in the combined output and thus determines a spectral characteristic of the light output through the aperture. A deflector shaped like a number, character, letter, or other symbol, may be coupled to a similarly shaped aperture. By combining several such fixtures, it is possible to spell out words and phrases, with selectable color lighting. Disclosed fixture examples use an extruded body member with appropriately located reflective surfaces, to form both the cavity and deflector.

Abstract: An emergency trunk release handle for an automobile displays the graphics explaining the use and function of the handle by cutting out the material from the handle. Forming the emergency release handle from a phosphorescent plastic material that can be formed by a molding process, such as injection molding, the cut-out graphics show as darkened areas, when viewed in the dark confines of an automobile trunk, to provide a high degree of visibility for the graphics. The graphics are also visible when seen against the dark carpet in the interior of an opened trunk cavity. The formation of the graphics is accomplished by coring the mold in the configuration of the desired graphics and by forming the plastic material in the mold around the cores. The resultant handle structure is thus formed in a cost effective manner that reduces the process failure potential during the manufacturing of the handle.
