Semiconductor laser beam bending
This study is about a single-component cylindrical structured lens with a gradient curve that was used for bending laser beams. It operates under atmospheric conditions and bends the laser beam independently of temperature, pressure, polarity, polarization, magnetic field, electric field, radioactivity, and gravity. A single-piece cylindrical lens that can bend laser beams was developed. Lenses are made of transparent, tinted, or colored glass and are used to undermine or absorb the energy of laser beams. This study is not a work of a plasma filamentation, nor is related to a self-accelerating wave packet. Rather, it focuses on bending the laser beam as required. The dimensions of the light-bending curvatures vary depending on the source and the lens. This is an application of laser beam bending. The dimensions of the captured images are 500 $\times $ 700 mm.
The invention relates to a radiating structure of an LED (light-emitting diode) lamp. The LED lamp comprises a substrate for bearing integrally packaged LED lamp beads, the radiating structure comprises a heat conducting part and a radiating layer exposed in the air, the heat conducting layer is fitted with the substrate, the outer side of at least part of the heat conducting part is coated with the radiating layer, the heat conducting part and the radiating layer are both made of heat conducting composite plastics, the heat conducting coefficient of the heat conducting part is greater than that of the radiating layer, and the radiating coefficient of the radiating layer is greater than that of the heat conducting part. The invention aims to provide the radiating structure of the LED lamp, which is good in heat radiating capability, convenient to process and easy for realizing automated mass production.
