Description
Technical Field
The invention relates to the technical field of optical films, in particular to a frosted microstructure anti-glare film and a plate material.
Background
Before the popularization of LED lamps, the traditional anti-glare lamp for office lighting is a grille lamp, the lamp light is hidden in a metal reflecting cover, the shielding angle reaches more than 30 degrees, and meanwhile, axial glare is further shielded by an aluminum partition at the outer side. The UGR <13 can be easily achieved by the traditional grille lamp, but for the LED panel lamp, the structure of the LED panel lamp is not suitable for anti-glare treatment, and high-angle light can be collected to a middle working surface only through an anti-glare film or a plate.
At present, anti-glare products commonly used for LED flat lamps comprise an extrusion-molded prism crystal plate and a hot-press-molded prism crystal plate. The extruded prismatic crystal plate is formed by directly extruding a prismatic crystal shape on the surface of a steel roller mould with a negative prism structure when a PS or PMMA plate is extruded and produced, the precision and the consistency of the prismatic crystal structure are difficult to guarantee during high-temperature forming due to the influence of thermal expansion and water absorption of the PS and PMMA, and in addition, a steel mould is easy to wear during continuous rolling at high temperature and needs to be repaired regularly. The other type of prismatic crystal plate is formed by heating an optical transparent PMMA plate and hot-pressing the optical transparent PMMA plate by using a large-size plane steel die, the process has higher precision than extrusion forming, but the cost is too high, the die opening cost of the large-size high-precision flat steel die is high, the investment cost of large-size hot-pressing forming equipment is also high, in addition, the hot-pressing production time of a single prismatic crystal plate is longer, and the efficiency is lower. The biggest defect of prismatic crystal plates produced by the two types of processes is that UGR <16 cannot be realized when lamp UGR test is carried out.
