Antecedentes de la invención Background of the invention
Se conocen en la técnica varios sistemas de tubos de LED cuyo objetivo es proporcionar tubos que puedan sustituir a los tubos fluorescentes usados actualmente, aprovechando los mismos tipos de conexión sin tener por tanto que realizar ninguna modificación en los portalámparas actuales.

Several LED tube systems are known in the art whose objective is to provide tubes that can replace the fluorescent tubes currently used, taking advantage of the same connection types without therefore having to make any modifications to the current lampholders. These LED tubes provide a diffused light that cannot be directed towards the specific area to be illuminated, which presents the main drawback of a large loss of light produced that is not used optimally.
El documento WO 2009/085529 da a conocer un aparato de iluminación de LED con una o más conexiones giratorias, de modo que puede ajustarse el ángulo de inclinación del aparato de iluminación de LED para dirigir la luz producida hacia una superficie o zona deseada. Sin embargo, aunque mejorando en parte la técnica anterior por permitir dirigir la iluminación hacia una zona concreta, esta solución es relativamente compleja y resulta por tanto costosa. Además, el aparato propuesto por este documento sigue presentando el inconveniente de que la luz emitida es difusa y por tanto no se aprovecha de manera óptima.

In addition, the apparatus proposed by this document continues to have the disadvantage that the emitted light is diffuse and therefore is not optimally utilized.
Por tanto, sigue existiendo en la actualidad la necesidad de un tubo de iluminación por LED que permita mejorar el aprovechamiento de la luz emitida por el mismo. Therefore, there is still a need for an LED lighting tube that allows to improve the use of the light emitted by it.
