1.Multiple lenses are scientifically arranged to achieve uniform mixed light. Based on the principle of mixing white light by the RGB primary color light source lens wavelength and combining with the ideal lighting effect of the lamp that conforms to the “△”(Delta) distribution, this product restricts the position and spacing relationship between multiple lenses in the optical module, so that the light emitted by multiple lenses in the same optical module can be fully mixed, with the same illumination effect in different directions, and meet the lighting needs of floodlights. 2.The similarity of light spots corresponding to different beam angles is high. Under the premise of restricting different lens positions and distances, this product changes the structure of the microstructure layer on the emitting surface to change the beam angle. As the beam angle increases, the three-dimensional shape or arrangement of the microstructures in the microstructure layer changes to ensure a high degree of similarity in light spots under different beam angles.
