Guitar (100) having a reinforced structure and consisting of mountable and/or dismountable components, the same guitar (100) comprising: - a main body (104) and a neck (102, 103) with a relative head (101), in which one end of the neck (102, 103) is connected to a respective housing (108) obtained in the main body (104), the connection occurs through primary coupling elements (130); the neck (102, 103) consists of a proximal part (103) and a distal part (102), in which the proximal part (103) and the distal part (102) are connected to each other at their respective ends through elements of secondary coupling (140), in such a way that the structure of the guitar (100) can be assembled and/or disassembled with respect to its three components, in correspondence with its primary (130) and secondary coupling elements (140), and these three components consist of: the main body (104), the proximal part (103) of the neck and the distal part (102) of the neck with respective head (101); in such a way that, after repositioning the strings (105) and/or their relative disassembly, it is possible to store the entire guitar (100), in a disassembled configuration, inside a container (110) of reduced dimensions that allows an easy transportation, the same guitar (100) characterized by the fact of further comprising: - a rigid bar (120), arranged longitudinally inside the above said neck (102, 103), and having a first section (121) and a second section (122), connected to each other through the above said secondary coupling elements (140 ), which in turn comprise reinforced interlocking means; the above said primary coupling elements (130) in turn comprise a reinforced interlocking mechanism, in such a way that the overall structure of the guitar (100) is particularly rigid and robust, and in such a way that the assembly and disassembly operations do not affect, over time, the stability of the above said primary (130) and secondary coupling elements (140).

A projector (1) with solid-state light sources (6) for street lighting or the like, comprises a case (2) that defines a main extension plane (Σ), a longitudinal axis (L) and a transverse axis (W) in mutually orthogonal relationship. The case (2) houses a plurality of LED light sources (6', 6", 6'") and a cap (3). Each of the LED light sources (6', 6", 6'") has a predetermined FWHM value and a main axis of the FWHM parameter (H, H', H", H'"). The cap (3) comprises a plurality of reflective surfaces (7', 7") for reflecting at least part of the emission of the LED sources (6', 6", 6'"). The LED sources (61, 6", 6'") are in such an arrangement relative to the reflective surfaces (71, 7") that none of them is subjected to at least one total reflection of the whole light emission within its optical FWHM parameter, at least one of the LED sources (6', 6", 6'") having its main optical axis (H', H", H'") oriented toward a target (T) without impinging upon none of said reflective surfaces (7', 7"). Advantage: reflections of the light emission within the optical FWHM parameter are reduced and the performance of the projector (1) is maximized.
