The present invention relates to a transparent electronic display board that is capable of uniform optical output and, more particularly, to a transparent electronic display board that is capable of uniform optical output wherein the pattern width and length are adjusted according to the sheet resistance of a transparent electrode of the transparent electronic display board, wherein a driving voltage applied to a light-emitting device can be uniformly supplied within a constant range, and wherein multiple light sources disposed in the transparent electronic display board can emit light at uniform intensity.

The invention relates to devices and methods that help deliver dynamic messages, including advertisements on placards, medallions, and lighted campaign signs. The augmented placard of the invention includes two components: a corrugated yard sign and a medallion. A stand holds the corrugated yard sign in a specific position. The corrugated yard design displays the first message, while the emblem contains the second message. The second message is preferably independent of the first message but may be related to the first message. The medallion embeds on the corrugated yard sign by a connecting element that provides a temporary attachment between the medallion and the corrugated yard sign. The placard can contain more than one medallion attached to it. Furthermore, the placard has the provision for attachment of an illumination source to maintain the visibility of the messages in any condition, including when it is dark.

An LED module is disclosed, which includes one or more LED light sources and one or more lenses. Each lens includes a lens body. The lens body includes an inner cavity having an incident surface, an emergent surface, and a reflective surface extending between the incident surface and the emergent surface for providing total internal reflection. One LED light source is situated in the inner cavity. Light emitted from the LED light source is transmitted by the incident surface. At least portion of transmitted light by the incident surface is reflected by the reflective surface to the emergent surface so as to provide a narrow light beam angle perpendicular to a length direction of the LED module. The emergent surface has a plurality of micro structures for enlarging a light viewing angle in the length direction. A sign box using one or more LED modules is also disclosed.

A stop sign brake light for vehicles includes a main body having an octagonal shape, a reflective border and the word STOP that is positioned along the center of the main body. A plurality of lighted elements are along an entirety of the reflective border and the word STOP, and a controller having a wiring harness for connecting to a vehicle power source.

A light-emitting device includes: a balloon, a light source disposed outside the balloon; and an optical fiber that connects the balloon and the light source and propagates light emitted by the light source. At least one of the balloon and the optical fiber becomes luminous by the light emitted by the light source.
