A portable lighting device includes: a coherent light source; a shaping optical system that shapes coherent light emitted from the coherent light source; and a diffractive optical element that diffracts the coherent light shaped by the shaping optical system to a surface to be irradiated (IP). The diffractive optical element is rotatably supported. The surface to be irradiated is lighted in a pattern depending on a diffraction pattern of the diffractive optical element.

The present invention corresponds to a smart post, which displays visual signals, either when people approach the smart post, according to a predetermined programming or in response to sensor parameters, the smart post comprises a structural body with an internal cavity, said structural body being made of a translucent material, a support body disposed in the internal cavity of the structural body, wherein the support body extends longitudinally along the structural body. Furthermore, the smart post comprises a light-emitting device located between the structural body and the support body, wherein the light-emitting device is supported on the support body, with a control unit connected to the light-emitting device.

The present invention also comprises a method for controlling a smart post, comprising the following steps: a) entering a configuration parameter in a control unit; b) generating a control signal in the control unit based on the configuration of step a); c) sending the control signal from the control unit to the light-emitting device; wherein the control signal of stage c) controls the light-emitting device to emit visual signals; wherein the visual signal may be text messages, images or light patterns.

A self-contained illuminated sign for mounting on a vehicle is disclosed. The sign includes a front panel, a rear panel situated opposite and substantially parallel to the front panel in spaced relation therefrom to define a space therebetween, and a light source comprising a plurality of LEDs. The light source is positioned between the front and rear panels and is configured to emit light that emanates from the front panel. The front panel is thus backlit to display indicia. A system for supporting a self-contained illuminated sign on a vehicle is also disclosed. The system includes the sign and a separate mounting frame mountable on a vehicle. The mounting frame is configured to removably receive the sign and, when the sign is received in the mounting frame, to surround a perimeter of the sign while permitting visibility of the front display area. Related methods are also disclosed.

Provided is a support system for replacing a linear fluorescent lamp with a light emitting diode (LED) module. The support system includes an elongated support member having one or more channel structures extending along substantially an entire length of the elongated support member. One or more ends of the elongated support member are configured for engagement with a socket. The support system includes at least one LED module mounted in mechanical engagement with the one or more channel structures by a fastening mechanism. The at least one LED module is positionable along a portion of the length of the channel structure.
