Abstract
High power Ultraviolet Light-Emitting Diode (UV-LED) is currently in high demand for a variety of applications including lighting, printing, and polymer curing, with its' advantages of durability, reliability, non-hazardous and safety. Recently, the technology of Semiconductor Light Matrix (SLM) by multiple individual LEDs mounted on panels was put forward to obtain higher power for curing application. However, the illumination uniformity of high power LED arrays still remains an issue. On the other hand, it has been also predicted previously that the lifetime of a device decays exponentially as the temperature increases. Therefore, the thermal management of high power LEDs is also a critical factor to the development of high-power UV-LED array light source. This paper presents our latest investigations of illumination uniformity and thermal management to satisfy the requirements of packaging UV-LED arrays for curing application.
