There are three key lens design schemes:
One, the lens is selected from the outside to face the scale armor, and the compound eye design scheme of the bright surface management center.
Two, the outer wall of the lens adopts a random slope design scheme, the near-bright surface is compound eyeball surface, the light-emitting angle is 250-600 adjustable, and the PC material is generally used. The reasonable transmittance of electron optics can be as large as 95%.
The three lenses and the second lens are generally made of PC material, which has high heat resistance. The light source can be integrated with SMD light source or COB light source. The light output angle is 300-600 adjustable, and the light output is uniform. During external vision, the integrated SMD light source can be sprinkled on the surface of the compound eyeball, and the visual impact is like COB, which expands the selectivity of the light source.
The optical lens is customized according to the parallel line of the center of the refractive index management of the 2 curved surfaces of the lens, which is called the main optical axis or main shaft bearing of the lens. There is a unique point on the spindle bearing, which will not change according to its light source dispersal orientation, which is called the optical center of the lens, and is indicated by the English letter "O". The convex lens can make the light source parallel to the main optical axis converge to a point on the main optical axis, which is called the focal point.
There is a focal point on both sides of the convex lens, and the relative symmetry with the optical center, the focal point is indicated by the English letter "F". The distance from the focal point to the optical center and center of the convex lens is called the focal length of the lens, which is indicated by the English letter "f". Because the convex lens has the effect of converging the light source, it is also called a converging lens. The light irradiated to the concave lens is more and more distributed after the concave lens, because the concave lens has the effect of dissipating the light source, so it is also called a dispersing lens.
When the distance between the object and the convex lens exceeds 2 times the focal length of the lens, it becomes a real image that is inverted and becomes smaller; when the distance between the object and the convex lens is between the 2 times the focal length of the lens and the focal length of the lens, it becomes a real image that is inverted and becomes larger; When the distance is lower than the focal length of the lens, it becomes an upright and larger person.
