Definitions
- the present invention concerns a reflector device having an internal structure in the shape of a regular pyramid, whose specular surfaces consist of isosceles, equal triangles, with a light or heat source provided onto the central median axis.
- the aim set forth is reached by means of the device according to the present invention, comprising an internal specular surface having the shape of a regular pyramid consisting of a plurality of isosceles triangles so as to have at the basis of said pyramid a shape of a regular polygon; the sum of the angles at the vertex of said triangles is of about 256" and the inclination is constant - about 32° - with respect to the central axis, where the light or heat source is provided, so as to produce a multipolar and not dazzling reflection.
- the specular surfaces of said isosceles triangles may be slightly concave instead of being plane.
- Figures 1 and 2 show an axonometric and transparent view of two variants of the reflector device with an internal structure in the shape of a regular pyramid having respectively a square and octagonal basis, and with a light or heat source on the central median axis.
- the enclosed figures show a reflector device with an internal structure in the shape of a regular pyramid, having a square or a polygon basis with a plurality of sides, comprising:
- a structure 4 of the reflector having the shape of a regular pyramid, consisting of a plurality of isosceles specular triangles 5, and the angles at the vertex, in correspondence with said sleeve 2, reach a sum of 256° when they are inclined of 32° with respect to the median axis M; said inclination remains constant even if the number of said isosceles triangles, and therefore the base polygon of said pyramidal shape - side 6 - varies;
- the number of the sides 6 of said base polygon and therefore the number of said isosceles triangles 5 and the pyramidal shapes of the structure 4 may change from three to any other number, maintaining the regular structure of the base polygon and the sum of the angles of the vertex of the isosceles triangles 5, corresponding to about 256°, so as to be each 64° in case of a square pyramidal structure and 32° in the octagonal structure.
