Description

Technical field The present invention is developed in the technical field of interior lighting, and in particular it relates to a recessed lighting appliance, in accordance with the preamble of claim 1. State of the art Lighting appliances are known in the art, such as for example spotlights, which can be mounted inside a wall, such as for example a false ceiling. Usually, such appliances are installed in the wall without protruding therefrom (so-called "flush" installation), or protruding by a minimum length. In detail, the aforesaid lighting appliances provide in their front part, a support structure, with a concave element and a rotatable support, rotatably mounted to the concave element. The edge of the concave element is usually placed flush with the wall, so that the concavity recesses towards the inside of the wall. Behind the concavity, i.e. inside the false ceiling, the rear part of the appliance is placed. For example, such parts of the appliance placed behind the concavity are a lighting assembly with a heatsink, and to them can be connected other components such as electronics and power and/or signal wiring. The lighting assembly comprises a lighting element that is visible through a central hole of the concave element. The rear elements, therefore, once the appliance is recessed, are hidden from view while the front part of the appliance is the one visible to the user. Lighting appliances are also known in which the lighting assembly is rotatable to change the orientation of the light beam, i.e., so that the light beam is no longer perpendicular to the wall in which it is installed but is actually inclined. In this case, the support structure of the spotlight remains fixed to the wall, while the lighting assembly rotates with respect to it. An example of a lighting appliance having a rotatable lighting assembly is shown in document JP 6405340 B2. Problem of the prior art With the rotation of the lighting assembly, spaces open up between the lighting element and the hole of the concave element. Consequently, components behind the optical assembly, such as the heatsink, cables, terminals, etc., which are usually aesthetically unpleasant, can potentially become visible again. In some prior art appliances, to overcome this problem a membrane is fixed between the concave element and the lighting assembly. With the rotation of the lighting assembly, the membrane stretches and keeps the rear parts hidden. However, usually in these solutions the membrane is only suitable for small inclinations of the lighting assembly, and therefore the functionality of the spotlight is limited. In other prior art appliances, for example the one shown in document JP 6405340 B2, the entire structure of the lighting appliance is shaped in a way that, by rotating the lighting assembly, the view of the components behind it is prevented or limited. However, these devices involve high manufacturing and design costs, as the entire apparatus must be shaped and specifically designed in advance, also taking into account the recess in which it will be installed. By way of example, the appliance of JP 6405340 B2 requires the provision of a fixed cover element, formed in the support structure, suitable for concealing the environment behind the lighting assembly on a side opposite to that of rotation. Furthermore, this appliance requires the formation of a sliding portion between the heatsink and the support structure, which is provided with specific guides along which a cover panel can slide during the rotation of the lighting assembly. It is therefore evident that the appliance of the aforesaid document needs to provide a priori a panel and respective guides on one side of the lighting assembly, and a cover element on the opposite side. Summary of the invention The object of the present invention is to solve the drawbacks mentioned in reference to the prior art, and in particular to provide a tiltable recessed lighting appliance in which the rear parts remain hidden, without limiting the functionality of the spotlight or the freedom of its design. This and other objects are achieved by a recessed lighting appliance according to any one of the appended claims. The lighting appliance of the invention provides a support structure, and a lighting assembly connected to the support structure and rotatable with respect to it. One or more cover flaps each have two end portions and a panel interposed between them. During the rotation of the lighting assembly with respect to the support structure, the first end portion remains constrained to the support structure, while the second end portion is constrained to move along the lighting assembly towards and away from the support structure. The panel of each flap, in a respective inclination of the lighting assembly, visually occupies a free space between the lighting element and the edge of the hole of the concave element. Advantageously, the panel of each cover flap can follow the rotational
