Abstract

A plurality of light emitting diodes (LEDs) disposed in a customized housing produce bright colored light simulating the appearance of a neon sign. The housing includes an opaque portion that reflects light from the LEDs and a translucent portion shaped in the form of an image or lettering that diffuses light from the LEDs. The inside surface of the opaque portion has a polished reflective surface while the outside surface has a dull textured surface. Light emanating from the LEDs propagates through the translucent portion of the housing appearing to a viewer as a bright uniform and colorful light similar in appearance to the light emitted from a neon sign.

Claims

1. A lighting apparatus viewable to a user comprising:

a base including

a first plurality of portions defining a first plurality of openings, and

a plurality of portions defining a plurality of concavities;

a plurality of light emitting diodes (LEDs) located within the concavities for emitting light; and

a flat translucent cover member mated to the base for diffusing light including

a second plurality of portions defining a second plurality of openings, the second plurality of openings corresponding in location to the first plurality of openings, and

a plurality of opaque inked portions located on a first side of the translucent cover member defining translucent indicia viewable to the user, the translucent indicia illuminated by the LEDs and configured to simulate a size and an appearance of a shaped neon tube in a neon sign,

wherein the first plurality of openings, the second plurality of openings, the plurality of opaque inked portions, the translucent indicia, and the plurality of LEDs cooperate with each other to simulate the appearance of the shaped neon tube.

2. The lighting apparatus of claim 1 wherein the translucent cover member includes a second side mated to the first side, the first side and the second side perpendicular to each other to aid in simulating the appearance of the shaped neon tube.

3. The lighting apparatus of claim 2 wherein the opaque inked portions define the translucent indicia to simulate gaps in the shaped neon tube which prevent portions of the shaped neon tube from touching itself.

4. The lighting apparatus of claim 3 wherein the cover member is made substantially of an acrylic material.

5. The lighting apparatus of claim 4 wherein the cover member has a frosted or sanded surface to diffuse light.

6. The lighting apparatus of claim 1 wherein the translucent indicia is lettering, images, or icons.

7. The lighting apparatus of claim 6 wherein ink deposited from a silk screen form the opaque inked portions.

8. The lighting apparatus of claim 1 wherein the plurality of portions defining the plurality of concavities include a smooth inner surface.

9. The lighting apparatus of claim 1 further comprising a control panel that controls a flash rate of the source of illumination.

10. A lighting apparatus viewable to a user comprising:

a base including

a first plurality of portions defining a first plurality of openings, and

a plurality of portions defining a plurality of concavities;

a flat translucent cover member mated to the base for diffusing light including

a second plurality of portions defining a second plurality of openings, the second plurality of openings corresponding in location to the first plurality of openings;

a plurality of opaque inked portions located on the first side of the translucent cover member defining translucent indicia viewable to the user, the translucent indicia configured to simulate a size and an appearance of a neon tube in a neon sign and the opaque inked portions define the translucent indicia to simulate gaps in the shaped neon tube which prevent portions of the neon tube from touching itself;

a second side mated to the first side, the first side and the second side perpendicular to each other to aid in simulating the appearance of the neon tube; and

a plurality of LEDs located in the plurality of concavities illuminating the translucent indicia,

wherein the first plurality of openings, the second plurality of openings, the plurality of opaque inked portions, and the plurality of LEDS cooperate with each other to simulate the appearance of the neon tube in the neon sign.

11. The apparatus of claim 10 further comprising means for controlling a flash rate of at least one of the plurality of LEDs to simulate the appearance of the neon tube when the neon tube is flashing.

12. The apparatus of claim 11 further comprising means for controlling the light intensity of the LEDs wherein the light intensity of the LEDS simulate a light intensity of the neon tube.
