TIR technology is the first application of Bi LED Projector Lens.
TIR lenses are formed by collecting and processing light based on the principle of total reflection. It is designed to use a penetrating spotlight in the front, and the conical surface can collect and reflect all side light. The superposition of these two kinds of light can achieve perfect light utilization and beautiful focusing effect. The efficiency of TIR lenses can reach more than 90%. It has the advantages of high light energy utilization, small light loss, small light focusing area, and good uniformity.
