Abstract

Dispositivo de alumbrado que comprende una cubierta (10) que presenta un perfil interior cóncavo adaptado para alojar por lo menos una fuente luminosa -provisto de unos medios aptos de soporte y de fijación, y de unos medios aptos de suministro energético- y un marco (11) destinado a comprender una pantalla (12), caracterizado porque presenta una curvatura sustancialmente cóncava de tal modo que, para cada dirección principal de emisión del rayo de luz de dicha por lo menos una fuente luminosa, es sustancialmente perpendicular a la dirección de la propia emisión de luz.

Claims (10)

1. Dispositivo de alumbrado que comprende una cubierta (10) que presenta un perfil interior cóncavo adaptado para alojar por lo menos una fuente luminosa -provisto de unos medios aptos de soporte y de fijación, y de unos medios aptos de suministro energético- y un marco (11) destinado a comprender una pantalla (12), caracterizado porque presenta una curvatura sustancialmente cóncava de tal modo que, para cada dirección principal de emisión del rayo de luz de dicha por lo menos una fuente luminosa, es sustancialmente perpendicular a la dirección de la propia emisión de luz.
2. Dispositivo según la reivindicación 1, caracterizado porque el perfil de curvatura de dicha pantalla (12) está conformado de tal modo que no permita ninguna emisión de luz hacia arriba con respecto a la dirección horizontal.
3. Dispositivo según la reivindicación 2, caracterizado porque dicho perfil de curvatura sustancialmente cóncavo de dicha pantalla (12) está constituido por una superficie única y continua, exactamente ortogonal con respecto a los rayos de luz correspondientes que proceden de dichas fuentes lumino-
sas.
4. Dispositivo según la reivindicación 2, caracterizado porque dicho perfil de curvatura sustancialmente cóncavo de dicha pantalla (12) está constituido por una superficie que a su vez comprende un conjunto de superficies de un tamaño inferior, caracterizada cada una de las mismas por ser ortogonales al rayo de luz incidente correspondiente.
5. Dispositivo según cualquiera de las reivindicaciones 1 a 4, caracterizado porque dichos medios de soporte y de fijación se disponen y se realizan de tal modo que se garantice que la iluminación producida por cada fuente luminosa individual utilizada presenta una orientación específica sustancialmente ortogonal a la parte de dicha pantalla (12) que corresponde a la misma.
6. Dispositivo según cualquiera de las reivindicaciones 1 a 5, caracterizado porque la parte exterior de dicha cubierta (10) presenta una serie de ranuras (13), delimitadas por unas aletas (14).
7. Dispositivo según la reivindicación 6, caracterizado porque dichos medios de soporte y de fijación y se disponen en filas sustancialmente paralelas.
8. Dispositivo según la reivindicación 7, caracterizado porque dichas aletas (14) se disponen en dichos medios de soporte y de fijación de tal modo que actúan como disipadores térmicos para el calor producido por dichas fuentes luminosas durante su funcionamiento.
9. Dispositivo según cualquiera de las reivindicaciones 6 a 8, caracterizado porque se realizan dichas ranuras a fin de permitir que la lluvia circule efectivamente hacia el exterior y para evitar el estancamiento del agua en el caso de que el dispositivo según la presente invención se utilice al aire libre.
10. Dispositivo según cualquiera de las reivindicaciones 1 a 9, caracterizado porque dicha cubierta (10) se caracteriza por un perfil redondeado y dichas aletas (14) describen unos arcos que se extienden sustancialmente desde un extremo de dicha cubierta hasta el otro.
