Except the adhesive force with the increase coating of etching concave point or salient point on coated face, can also little lattice point (salient point) be set at that side surface of the uncoated coating of diffuser, can play good sheen effect to light equally, such as the inboard coating composition of the safety glass of diffuser, and forming numerous little lattice points in the outside of safety glass, these little lattice points can play astigmatic sheen effect equally.Can certainly be coating composition and salient point is set at inner surface or the outer surface of diffuser on the reflective surface of reflector, also can salient point be set at the reflective surface of reflector conversely and at the inner surface of diffuser or/and the outer surface coating composition.
In addition, also can be on the reflective surface of the inner surface of diffuser and reflector the two one of or concave point all is set, and at the outer surface Coating of diffuser, or at the reflective surface of reflector concave point is set, and at the inner surface of diffuser or/and Coating on the outer surface.
Comprehensive, the face that arranges of sags and crests and the coated face of coating can have multiple combination, and the technical staff can decide as required.Namely in the reflective surface of the interior outer surface of diffuser and reflector, can not be provided with salient point (lattice point) or concave point on the face of coating composition, and salient point or concave point can be set and coating composition only on the coated face of coating composition, also can be after on the coated face concave point or salient point being set still coating composition again, with the effect of further reinforcement sheen and increase adhesive force.
Because when the outer surface of diffuser arranged concave point, some organic particles that do not decompose fully can be deposited in the concave point gradually in airborne dust and the vehicle exhaust, affect luminous efficiency and the brightness of LED lamp, also are difficult to wash, and were therefore not preferred.
In addition, above-mentioned concave point or salient point as etching on diffuser or reflector, be called at the face with etching concave point or salient point in the situation of etched surface, can be only etching concave point or salient point on an etched surface, also can be that existing concave point has again salient point on the etched surface, mix to arrange, perhaps to the adhesive force that increases coating, the sheen effect of light is more produced effect.
