Campo de la invencionField of the Invention

[0001] La presente invencion se refiere al campo tecnico de los aparatos de iluminacion y, en particular, al campo tecnico de los aparatos de iluminacion que comprenden reflectores adaptados para optimizar la emision de luz.[0001] The present invention relates to the technical field of lighting apparatus and, in particular, to the technical field of lighting apparatus comprising reflectors adapted to optimize the emission of light.

Estado de la tecnicaState of the art

[0002] Se conoce el modo en que uno de los parametros mas importantes en relacion con los aparatos de iluminacion esta constituido por su emision de luz. Los reflectores, difusores y dispositivos de emision de luz estan disenados y elegidos para proporcionar condiciones de iluminacion precisas, en terminos de diagrama de emision e intensidad de luz emitida.[0002] It is known how one of the most important parameters in relation to lighting apparatus is constituted by its emission of light. The reflectors, diffusers and light emitting devices are designed and chosen to provide precise lighting conditions, in terms of emission diagram and emitted light intensity.

[0003] En el caso de aparatos de iluminacion del tipo suspendido, el diseno de la emision de luz del propio aparato tiene lugar de una manera relativamente mas simple con respecto al caso de los aparatos de iluminacion equipados, por ejemplo, con postes de soporte para la fijacion al suelo. Un aparato de iluminacion para el montaje en un poste se divulga en el documento US 6502 965 B1. De hecho, en este caso, el diagrama de emision, y por lo tanto la emision de luz general del aparato de iluminacion, esta fuertemente influenciado por la presencia de dichos soportes que a menudo se colocan en posiciones tales como constituir un obstaculo para la propia emision y, por lo tanto, proyectar areas de sombra sobre el objeto o sobre el area que se va a iluminar.[0003] In the case of lighting apparatus of the suspended type, the design of the light emission of the apparatus itself takes place in a relatively simpler manner with respect to the case of lighting apparatus equipped, for example, with support posts for fixing to the ground. A lighting apparatus for pole mounting is disclosed in US 6502 965 B1. In fact, in this case, the emission diagram, and therefore the general light emission of the lighting apparatus, is strongly influenced by the presence of said supports that are often placed in positions such as constituting an obstacle to the own emission and, therefore, project shadow areas on the object or on the area to be illuminated.

[0004] Esta desventaja es mas importante cuanto mayores sean las dimensiones de los postes de soporte del aparato de iluminacion que se encuentran en la posicion intermedia entre los dispositivos de emision de luz y el objeto o el area que se va a iluminar, y es evidente la necesidad de evitar el problema tecnico descrito para recuperar la fraccion perdida del flujo de luz y obtener una emision de luz optima o casi optima, incluso en presencia de aparatos de iluminacion equipados con postes de soporte para la fijacion al suelo.[0004] This disadvantage is more important the larger the dimensions of the support posts of the lighting apparatus that are in the intermediate position between the light emitting devices and the object or area to be illuminated, and is The need to avoid the technical problem described to recover the lost fraction of the light flow and obtain an optimal or almost optimal light emission, even in the presence of lighting equipment equipped with support posts for fixing to the ground.

[0005] Por lo tanto, un objeto de la presente invencion consiste en proporcionar un aparato de iluminacion, que comprenda, por ejemplo, postes de soporte para la fijacion al suelo o a las paredes, adaptados para emitir una iluminacion optimizada y para corregir la presencia de posibles areas de sombra causadas por dichos postes de soporte y garantizar una correcta iluminacion del objeto o area que se va a iluminar.[0005] Therefore, an object of the present invention is to provide a lighting apparatus, comprising, for example, support posts for fixing to the floor or walls, adapted to emit an optimized lighting and to correct the presence of possible shadow areas caused by said support posts and guarantee a correct illumination of the object or area to be illuminated.
