  • Patent number: 9960311
    Abstract: An illuminated address display for a building and residence having a housing with a front wall with an inclined upper portion and vertical lower portion, solar cells on the inclined upper portion and a group of small rectangular panels suspended from the lower portion of the housing. On the small rectangular housing there is an address identifier consisting of alphanumeric digits which disclose the address of the residence or building. The alphanumeric digits have segments which extend through the panels and are backlit by light emitting diodes which are mounted on a removable cover on the bottom of the housing. Inside of the housing are batteries and a solar charge controller to prevent overcharging of the batteries and an “on/off” switch.

  • Publication number: 20130255116
    Abstract: An illuminated sign having a housing unit with a frame and one or more light emitting arrays to provide visible indicia and a backlight module for mounting a transparent backlight panel which is held in close contact with a reflection panel and optically positions a light emitting unit to emit light through the backlight panel for emission from the front of the sign. The replaceable sign member accommodates the display of visible indicia and is backlit by the light emitting unit. A light sensor is mounted on the backlight module for measuring ambient light. The light emitting unit can be driven by a signal from the light sensor to automatically set a contrast level of illumination to optimize the information presented by the illuminated sign.

  • Patent number: 7472506
    Abstract: A lighted sign having a front translucent surface surrounded by a skirt defining an opaque contour. A light diffuser is located behind an opaque zone of the skirt. Light is radiated from an internal light source through the light diffuser to provide an illuminated background for the opaque contour thereby increasing the contrast of the silhouette of the sign on a mounting surface. The front translucent surface is preferably back lit by the same internal source of light.

  • Patent number: 7360910
    Abstract: An illuminated sign, internally illuminated by a source such as one or more LED'S generally located at one end, and having a character panel with at least partially transmissive portions to define the characters of the sign. The character panel is curved so as to face the source more squarely at distances further from the source. By this arrangement, the geometric fall-off of illumination with increasing distance from the source is compensated for by the curvature of the character panel, such that more uniform illumination is provided than with prior art flat panels. Power management systems for solar charged illuminated signs are also described, in which the illumination level of the sign is adjusted according to the ambient solar flux and according to the charge-holding capacity of the battery. The system also warns of the impending end of battery life without interrupting the sign functionality.

  • Publication number: 20080060236
    Abstract: A sign panel made of light transmitting material, has a front displaying side and a rear side, the sign panel has a background portion that is preferably a flat surface and a protruding portion that forms a sign character, wherein a lighting blocking layer attached to said background portion of the sign panel, and a highlight coating coated on said protruding portion of the rear side of the sign panel. Light can go through the protruding portion with a highlight coating. The sign panel can use without a complicated neon light tubes, and the sign panel contains no mercury versus argon based neon tubes. This is a huge win from the environmental side as there is no use for mercury inside LED signs.

  • Patent number: 5255459
    Abstract: The new framing system for signs provides a method of stretching the flexible sign material across the opening of a frame. The tensional devices are installed manually from the outside of the sign at regular spacings on the edges of the flexible sign material. The tensional devices are installed by closing the device on, and by the same movement, puncturing retaining holes on the edges of the flexible sign material. The adjustment of the tension of the flexible sign material is done by pushing inwardly on each tensional device to engage it onto a series of serrations inside a slot facing outwardly along the edges of the frame. The outside edges of the frame are held rigid with frame members extending from the bottom of the sign, and thus eliminating the need for support members, between the flexible sign material and the lamps, which normally transmit shadows to the face of the sign.

  • Patent number: 5154014
    Abstract: Apparatus for enhancing a message comprises an elongated housing defiing an open front for releasable positioning of a first message panhel having opaque and transparent portions constituting the message of one's choice. A stationary fluorescent light tube is positioned within said housing. A multi-colored, translucent tubular sleeve is positioned for rotation about said light tube such that light passes through said sleeve to emit a seemingly moving array of colored lights. A trough-shaped reflective panel is positioned behind the light and sleeve within the housing such that light impinged upon its reflective surface is reflected to impinge upon the message panel to thereby appear through the transparent portions of the message panel and visually enhance the message. A second message panel which is translucent and textured may be placed behind the first message panel to make the light appearing therethrough seem patterned.

  • Patent number: 4373282
    Abstract: A device for illuminating a display surface. Light is introduced through an end surface of a transparent substrate having front and back plane parallel opposed surfaces and thereby directed into the interior of the substrate. The back surface is textured with a multiplicity of shallow depressions such as grooves or dimples which have shallow sloped sides. These sides are configured so that light is selectively directed from the interior of the substrate through a limited angle out of the substrate towards a display surface adjacent and coextensive with the back surface of the substrate and away from a viewer observing the display surface through the substrate. The device provides uniform, high contrast illumination of underlying large area graphic displays such as maps, photographs, charts, and the like.
