Abstract
A display device has a support, a tubular light source, and a cover. The light source is interconnected to the support, and the cover is placed over the light source. The cover is an arc-shaped partially translucent elongated member. The cover is colored to create a glowing effect when light emitted from the light source passes through the cover in a forward direction. Light emitted from the light source in a rearward direction reflects off of the support. The cover allows the light source to create both a glowing effect and a back-lit effect.
Claims13
A display device comprising:
- a tubular light source:
- a reflective surface adjacent to the light source;
- a cover disposed on the light source, wherein the cover has at least one of an arc-shaped and a circular shaped cross-section, and is disposed such that a rearward portion of the light source emits light that is reflected off of the reflective surface, the cover including
- a rearward-facing section facing toward the reflective surface and
- a forward-facing section facing away from the reflective surface, the forward-facing section being colored with a first color, and the rearward-facing section being at least one of uncolored and colored with a second color different from the first color.
A display device comprising:
- a tubular light source;
- a reflective surface adjacent to the light source;
- and
- a cover disposed on the light source, wherein the cover has at least one of an arc-shaped and a circular shaped cross section, and is disposed such that a rearward portion of the light source emits light that is reflected off of the reflective surface;
- wherein the cover is coupled to the light source with wire ties.
A method of constructing a display device comprising the steps of:
- providing a reflective surface;
- providing a tubular light source spaced from the reflective surface, the tubular light source having a cross-section with a first circumference;
- providing a tubular extrusion having a cross-section with a second circumference being smaller than the first circumference;
- slitting the tubular extrusion;
- and
- placing the tubular extrusion on the tubular light source, such that the cover does not extend completely around the tubular light source in a radial direction.
A display device comprising:
- a reflective surface;
- a tubular light assembly positioned adjacent the reflective surface and including:
- a tubular light source and
- a cover disposed on the tubular light source and having at least one of an arc-shaped and a circular shaped cross section, the tubular light assembly emitting light having a first color in a first direction toward the reflective surface and emitting light having a second color in a second direction away from the reflective surface, the second color being different than the first color.
A method of constructing a display device comprising the acts of:
- providing a reflective surface;
- providing a tubular light source spaced from the reflective surface;
- providing a tubular extrusion;
- slitting the tubular extrusion;
- placing the tubular extrusion on the tubular light source;
- and
- emitting light having a first color from the tubular light source away from the reflective surface and emitting light being at least one of uncolored and a second color different from the first color from the tubular light source toward from the reflective surface.
