Abstract

The invention concerns an economical and self-powered electronic luminous display or signalling device, using the properties of an optical part and light sources (LED, micro-lamps), with low consumption of energy and high light output thereby providing self-sufficient power supply through wind or solar energy. The device consists of a section (1), containing an insulating casing (2), wherein are arranged light sources (4), whereof the point light is spread by an optical part (13) before penetrating through the field (f) of a translucent plate (c). The photoelectric cell (12) controls the opening and closure of power supply (9) whereof the low-voltage electrical power is self-produced by an air turbine (11) or solar collectors (14) through an alternator (7) and a voltage regulator (8). A remote-control (19) antenna (18) provides all remote control functions. The inventive device is designed for signalling or displaying, especially where for economic reasons a device self-sufficient in electrical power is required.

The present invention relates to an autonomous electronic light display device, very energy efficient, powered by wind or solar energy, and using the properties of LEDs, light-emitting diodes, micro-lamps or light tubes, <B> to </ B> low energy consumption and <B> at </ B> strong luminous efficiency, whose point light spread by an optical part, penetrating through the polished field (s) of a translucent plate, allows the luminous display information viewed through transparency.

This type of plate is usually made with acrylic glass type materials (Affuglas R # plexiglass R # perspex R <B> ...) </ B> having a refractive index identical or similar to that of glass.

The illumination by its field of this type of transparent plate intended <B> to </ B> the luminous display, contrasted or not on an opaque background, was traditionally obtained by means of fluorescent lamps or tubes <B> to < Neon-type cold cathode, affixed in parallel, against or above the polished field of the transparent plate, the portion of light channeled in this kind of optical fiber, being reflective before or after having crossed the opposite field by which Escape the light.

The relatively high consumption of this type of lamps (4W <B> to </ B> 56W according to the formats <B> to </ B> illuminate), powered mainly by 220 voices, their duration of <I> life </ I > relatively short <B> (7000 to 15000 </ b> hours), their relatively high heat release with their feed ballast <B> (50 to </ B> 70 "), the impossibility to make them blink (safety or road information <B> ...), </ B> pulsed illumination of whitish color (colored glass), and their size limited their use <B> to </ B> a wired power supply by the electrical sector without autonomous power supply.

These sets were therefore most often made of a metal section containing the lighting source and pinching the translucent plate (s) serving as support <B> for the display or signaling.

In this state of the art the process could not benefit from the technologies of electronics and its various principles of use (blinking, illumination of various geometric shapes <B> ...), </ B> as well as from the weak consumption making it possible to have an independent power supply.

<B> 60) </ B> Distribute the point and directional light rays from the light-emitting diodes or micro-lamps, to obtain a homogeneous light, scattered and distributed as evenly as possible over the range of illumination intended <B > to </ B> receive the display.

<B> 70) </ B> In the case of single field illumination of the translucent plate, reflect the light at the best angle before it escapes through the opposite field <B> to </ B > his penetration.

Once the above-described problems have been solved, the most remarkable advantages of the disposifif are: <B> - </ B> its low consumption and its high luminous efficiency, <B> - </ B> its energy independence allowing the use out of the vicinity of the power grid.

<B> - </ B> its duration of illumination <B> (150,000 to <200,000 hours).

<B> - </ B> its diversity of applications by its operation <B> to </ B> base of allied electronics <B> to </ B> the property of LEDs or light-emitting diodes, (blinking, remote control, plurality of colors with the same lamp).
