The present invention relates to an Illuminated Roll Up Sign. The traffic sign comprises a rollable sign member and a hand-held base member. The traffic sign of the present invention is light weighted and can be disassembled and packaged for the ease of storage and/or transportation.

The present invention provides lighted signs and in particular electronic signs having embedded or integral light sources and in particular to lighted signs that have field replaceable lights and field replaceable face plates, and which preferably are controlled by an Internet-connected controller and which preferably includes an integral solar panel mount and an integral battery box mount, and still preferably include radios for pole-to-pole/machine-to-machine communication for synchronized control, and such products preferably having an additional network connection for Internet connectivity, such as by way of GPRS/GSM/cellular gateway functionality, WiFi, LAN, fiber optic or other network connectivity.

A light-emitting sign comprising a light source for emitting light, in which the light-emitting sign may be thin (e.g., comparable to a conventional non-light-emitting sign) while creating a desired visual effect using the light emitted by the light source. This may be achieved, for example, by the light source being thin itself and/or by having an external device connected to the light-emitting sign and implementing certain functionalities (e.g., powering and/or controlling the light source).

An information conveying apparatus may include a stick figure structure. The stick figure structure may include an elongated torso member including a first end and a second end, a head member operably joined to the first end of the torso member, a first arm member and a second arm member operably joined to either side of the torso member between the first and second end of the torso member, and a first leg member and a second leg member operably joined to the second end of the torso member. The information conveying apparatus may further include a support structure for maintaining the stick figure structure in a substantially upright position. The support structure and the stick figure structure may be formed as an integral body. The support structure may be separate from the stick figure structure.

A foldable warning triangle assembly (100) comprising three arms (112,114,116) configurable as a triangle. The three arms (112,114,116) are configurable as a triangle, wherein the three arms (112,114,116) are pivotably connected together at pivot points (118,120,122) such that they can pivot into a collapsed arrangement without disconnecting the three arms (112,114,116). The assembly (100) also comprises an electrical switch within a first arm of the three arms (112,114,116) arranged adjacent a pivot point between the first arm of the three arms and a second arm of the three arms. Further, a surface of the second arm is arranged to apply force on the electrical switch such that the electrical switch is configured to close when the three arms (112,114,116) are fully configured as a triangle thereby completing an electrical circuit of the warning triangle.

A sign or other marking that is illuminated by an LED lamp, e.g., in a vehicle headlamp is described. The sign employs spectral shifting to increase the power or energy reflected by the sign when illuminated by the LED lamp, which has a significant power peak in the blue spectrum. The spectral shifting can be done in a conversion layer on top of a reflective layer. The reflective layer can include quantum dots to increase its efficiency in reflecting light.

The improved traffic signal indicating sign may be coupled to a motorist warning such as a traffic signal or to a traffic sign in advance of the traffic signal. The improved traffic signal indicating sign may extend beyond the edges of the motorist warning to which it is coupled and may call attention to the motorist warning. A backplate surrounding the motorist warning may comprise an inner border and an outer border. The inner border may comprise a plurality of border indicator lights which may be associated with the traffic signal and may be communicatively coupled, either directly or indirectly, to a controller for the traffic signal such that the border indicator lights may change to reflect the state of the traffic signal. The outer border may comprise a reflective strip to further increase awareness.

A light-emitting diode lighting structure for improving back-illumination efficiency is revealed. The light-emitting diode lighting structure is disposed on a substrate and composed of a light emitting diode (LED) and a reflective panel. The LED provided with a packaging lens has a light emitting side and a backside. The reflective panel is arranged at the light emitting side of the LED and located adjacent to the packaging lens. A part of light emitted from the light emitting side is reflected to the substrate by the reflective panel. Thereby the illumination on the substrate at the backside can be increased. Moreover, continuous lighting is generated so that messages shown on signboards can be read more clearly and comfortably when a plurality of LEDs is disposed on and applied to the signboards.

A self-propelled warning device used for road safety includes a bracket, a warning sign mounted to an upper side of the bracket, and at least one driving mechanism. The driving mechanism includes a supporting leg, a driving unit, and a wheel. The supporting leg includes a receiving portion, the receiving portion defines an accommodating space. The driving unit is accommodated in the accommodating space. The wheel is mounted on the receiving portion and is drivingly connected to the driving unit. The wheel is driven by friction of the driving unit. The driving mechanism is also disclosed.
