Novel Method

This paper experimentally investigates light intensity distribution in a paraboloid of thin shell irradiated by a laser. Light intensity distribution needs to be understood for solar energy heat receiver or laser drilling cavity. A novel method is utilized to measure the light intensity distribution in a paraboloid of thin shell irradiated by a laser. The results are explained by simple geometric optics.

Freeform Lens

In this study, our proposed ultraviolet light-emitting diode (UV LED) mosquito-trapping lamp is designed to control diseases brought by insects such as mosquitoes. In order to enable the device to efficiently catch mosquitoes in a wider area, a secondary freeform lens (SFL) is designed for UV LED. The lens is mounted on a 3 W UV LED light bar as a mosquito-trapping lamp of the new UV LED light bar module to achieve axially symmetric light intensity distribution. The special SFL is used to enhance the trapping capabilities of the mosquito-trapping lamp. The results show that when the secondary freeform surface lens is applied to the experimental outdoor UV LED mosquito-trapping lamp, the trapping range can be expanded to 100π·m2 and the captured mosquitoes increased by about 300%.
