Abstract

Abstract This work reports an optomechanical, electronic system consisting of LEDs emitting light in the near-infrared region. The 147 light-emitting diodes were distributed in a semi-spherical dome so that each focused light upon the center of the radius. The LEDs received electrical polarization so that the optical power of each provided 16 ± 0.36 mW for a total of 2.4 W. The developed system allows multifunctional applications in phototherapy, making it possible to perform this clinical technique for the treatment of skin lesions and contusions at the musculoskeletal level. The geometry of the developed system also allows the use of phototherapy in the treatment of neurological pathologies. In terms of instrumentation, the three-dimensional light intensity distribution and the thermographic images were obtained using three working distances from the system to the target. Three-dimensional light intensity distributions were obtained considering each working distance. These were inserted in the thermographic images as indications of the emitted temperature distributions. This work verified that the optomechanical and electronic system developed with LEDs may be used for multiple applications in phototherapy.

用于光疗应用的基于LED的光机仪器的开发

摘要:本文报道了一种由发光二极管组成的光机械电子系统，该系统在近红外区域发光。147个发光二极管分布在一个半球形的圆顶中，这样每个发光二极管都将光聚焦在半径的中心。led接受电偏振，每个led的光功率为16±0.36 mW，总计为2.4 W。开发的系统允许在光疗中的多功能应用，使得在肌肉骨骼水平上执行这种临床技术来治疗皮肤病变和挫伤成为可能。开发系统的几何结构也允许在神经系统疾病的治疗中使用光疗。在仪器方面，利用系统到目标的三个工作距离，获得了三维光强分布和热成像图像。得到了考虑各工作距离的三维光强分布。这些被插入到热成像图像中作为发射温度分布的指示。这项工作验证了用led开发的光机械和电子系统在光疗中的多种应用。

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
