The disclosure relates to light modules using light emitting diodes (LEDs) and more particularly to LED based light modules for existing sign boxes. One embodiment of a light module according to the present invention can comprise an elongated support structure having a plurality of surfaces and comprising a plurality of support structures joined together to form an overall support structure of a desired length. A plurality of light units can be included wherein at least some of the lighting units comprise a first light unit array on one of the support structure surfaces, and others of the said light units comprise a second light unit array on another one of the support structure surfaces. Conductors are arranged to connect the first light array in a series interconnection and to connect the second light array in a respective series interconnection.

[Object] Construct a system for freely changing images to be displayed or displaying images at appropriate timing

[Solution] Control system for controlling the rotating displays. light emitting elements arranged in a line on a rotating plate.

A server stores image data in a storage device and transmits the image data to the rotating displays. The storage device stores user data. user data includes a type of each rotating display held by the user. The user data includes a time schedule for displaying the image data. The server supplies to the terminal device an operation screen for user interface. User interface allows to select the image data and a time schedule for displaying the image data, or allows the user to create displayable image data. The server has a display controller that transmit to the rotating displays the image data, that selected or created by the user and transmit the data indicating the time schedule.

A optical device includes a waveguide plate, which includes an in-coupling element to form first guided light (B1) and a second guided light (B2) by diffracting input light (IN1), an expander element to form third guided light (B3) by diffracting the first guided light (B1), an out-coupling element to form first output light (OB3) by diffracting the third guided light (B3), a bypass element to form fourth guided light (B4) by diffracting the second guided light (B2), wherein the first guided light (B1) propagates in a first direction, the second guided light (B2) propagates in a second direction, and the angle γ12 between the first direction) and the second direction is in the range of 60° to 120°, wherein the out-coupling element includes one or more augmenting regions.

A display apparatus includes a display panel supported within a case having a rear surface including a circular recessed portion. An annular total reflection mirror and an annular half mirror are disposed in the circular recessed portion with an annular light source provided therebetween. A pattern forming member is disposed on an outer side of the annular half mirror and is configured to be reflected by the annular total reflection mirror. A pattern light source is configured to supply light to the pattern forming member so that the pattern is reflected on the annular total reflection mirror. When the annular light source and the pattern light source are turned on, the pattern of the pattern forming member is reflected between the annular total reflection mirror and the annular half mirror.

Old address signs are retrofitted, incorporated and integrated with new electronic devices for navigation aid, Internet and IOT (Internet Of Things) related applications. New smart address sign with Internet connections has the capabilities of remote sensing and detecting useful information for residential homes and business offices. Useful information is gathered, stored, processed and relayed for applications of improving home and office efficiency, security and safety related solutions. New hardware and software built into the smart address signs also serve as wireless signal repeating/relaying base stations.
