• the redirection optics 5 is against or as here fixed peripherally by a double-sided adhesive or an adhesive 63 to the face F2.
• a rear PVB sheet 22 is also added.
• Figure 10 is a sectional view of a glazing 1 10 (bezel or baffle) with LEDs collimated light and redirected according to the invention. This figure differs from the previous one in that the diode 4 is reverse-mounted, the diode support 3 is closer to the face F2 and is perforated and receives the optics 5a, 5.
• the diode support 3 is closer to the face F2 and is holed and receives this optical.
• Figure 1 1 is a sectional view of a glazing 120 (bezel or deflector) with LEDs with collimated light and redirected according to the invention.
