Four-chip encapsulation lens
Four-chip encapsulation is a common configuration for UV LEDs that pursue single-point high intensity, mainly for short-distance irradiation, such as printing or curing. Without any aging phenomenon, it is very suitable for short-distance industrial UV LEDs.
However, in terms of optics, the geometric alignment of four arrayed chips and the optical lens is not optimized, therefore there are still limitations for application. Deviated optical axis of the four-chip encapsulation is not suitable for long-distance applications, such as exposure systems and surface sterilization modules. For such applications, please refer to the array encapsulation lens design.
