Abstract

The present invention relates to a light effect generator in which a spontaneous emission light source associated with filters or lenses is used so as to obtain a light beam with the desired colour and divergence.

Description

La présente invention a pour objet un dispositif permettant de tracer des courbes sur un écran, ou des surfaces dans l'air si celui-çi est charge de particules réfléchissantes , telles que poussieres, fumée, permettant de rendre visible un rayon lumineux sur son trajet. The present invention relates to a device for drawing curves on a screen, or surfaces in the air if it is loaded with reflective particles, such as dust, smoke, allowing to make visible a light ray on its path .

On connait déja de tels dispositifs utilisant un rayon lumineux émis par un LASER et dont la direction peut etre modifiée par un système de miroirs mobiles à axes orthogonaux commandés en rotation par des moyens adéquats. We already know of such devices using a light beam emitted by a LASER and whose direction can be changed by a system of movable mirrors with orthogonal axes controlled in rotation by adequate means.

De .tels appareils sont utilisés dans des lieux publics, discothéques, salles de spectacle, aires da publicité. Such devices are used in public places, discotheques, performance halls, advertising areas.

Mais l'utilisation d'un faisceau LASER dans des lieux QU le public est aamis est soumis a des règlements très stricts en raison des dangers d'illumination et qui limitent considerablement le domaine d'emploi de ces appareils. But the use of a LASER beam in places WHERE the public is friends is subject to very strict regulations because of the dangers of lighting and which considerably limit the field of use of these devices.

La présente invention consiste à remplacer le LASER par une source de lumière a émission spontanée. The present invention consists in replacing the LASER by a light source with spontaneous emission.

Un rayon lumineux de faible divergence peut etre obtenu en d'une source de lumiére quasi ponctuelle 1, d'une lentille convergente 2, d'un diaphragme 3 placé au foyer d'une lentille convergente 4. La divergence du faisceau est égale au rapport d/F, d étant le diametre du diaphragme et F la distance focale de la lentille 4. A light beam of low divergence can be obtained from a quasi-point light source 1, a converging lens 2, a diaphragm 3 placed at the focus of a converging lens 4. The beam divergence is equal to the ratio d / F, d being the diameter of the diaphragm and F the focal length of the lens 4.

En disposant en 5 un système de filtre à variation discrète ou continue de couleur on peut colorer le faisceau sortant 6. By having a filter system with discrete or continuous color variation at 5, the outgoing beam 6 can be colored.

On dispose le filtre en 5 afin que celui-çi soit de petite dimension, donc d'inertie réduite ce qui permet de modifier rapidement la couleur du faisceau, une fréquence de lUO Hz est courante. Cette faculté permet d'obtenir des effets colorés nouveaux. We have the filter in 5 so that it is small, therefore of reduced inertia which allows to quickly modify the color of the beam, a frequency of 10 Hz is common. This faculty makes it possible to obtain new colored effects.

Par rapport au LASER ce dispositif permet de choisir la couleur du faisceau sans etre tributaire de raies imposées par le type de LASER utilisé.  Compared to LASER this device allows you to choose the color of the beam without being dependent on lines imposed by the type of LASER used.
