LED lenses are generally divided into primary condensing lens and secondary condensing lens. The primary condensing lens is a silica gel lens, which is usually directly packaged on the LED chip because of its high temperature resistance (or over reflow soldering). Generally, the silica gel lens has a small volume and a diameter of 3-10mm. And LED lens is generally closely connected with LED, which is helpful to improve the light output efficiency of LED and the optical system where the lens changes the light field distribution of LED. Optical grade PMMA/PC or glass is generally used as the material of the secondary focusing lens. The secondary lens and LED are two independent objects, but they are inseparable in application. The function of the secondary lens is to focus the luminous angle of the LED light source again into any desired angle between 5 ° and 160 °. The distribution of the light field can be mainly divided into round, oval, rectangular, etc. The specifications of the secondary focusing LED lens are classified into penetrating (convex lens), Catadioptric (cone or cup type), lens module type.
