Product composed by an optical unit and a recess box, to be purchased separately. The recess box is manufactured in extruded primary aluminium, anodized in black colour. Patent pending optical group, consisting of a system of lenses made of aluminised PMMA. The optical group, with IP65 protection rating, can be connected in series or in parallel in order to create almost infinite lines of light. The PCB is protected by conformal coating process, which prevents oxidation. Before fixing the diffuser on the Platek products a Pre-treatment using an atmospheric pressure plasma process is carried out on the surface. The process activates the ionic load on the surface exactly where it is needed, thus promoting the best silicone grip possible and removing any residual release of agents for a longer lasting seal. The next steps are the coating of silicone and the assembly of the diffuser on the lighting fixture, with an automated process to guarantee the perfect sealing of the lamp.
