[00078] According to a preferred embodiment, on the other hand, the transparent portion 44 extends perimetrically along the entire side wall 43, ie at 360 degrees, as shown by way of example in figure 2?.

[00079] In other words, the lighting assembly 1 has a chamber 40 and a transparent portion 44 of larger dimensions than those necessary for the punctual or defined lighting required. Thanks to these characteristics, the lighting assembly 1 has a desired aesthetic effect, both in the off configuration and in the particular on configuration. With the transparent portion 44 extending perimetrically, the lighting assembly 1 appears to be specifically suited to perform 360° lighting, but by virtue of of the presence of the angular opening 65, the lighting assembly 1 illuminates the external environment in a punctual manner, for example for a 90?, 180?, or 270? line. according to the size of the angular opening 65. In addition, thanks to the exploitation of the reflection of the light beam, the entire chamber 40 is in any case illuminated at 360?.

Advantageously, the lighting assembly ? suitable for illuminating a walkway, leaving surfaces of less interest in dim light or shade, such as a hedge or a low wall. In other words, advantageously the lighting assembly clearly delimits the region of the floor or wall illuminated by an intense light beam, leaving the other regions in shadow.

[00083] Advantageously, the lighting assembly ? suitable for lighting, i.e. for presenting the room lit in its entirety, regardless of the directionality? of the intense light beam.
