    摘要: A method for monitoring temperature in at least one location of an electromagnetic coil assembly having at least one electrical winding. The method includes passing a light through a non-magnetic optical fiber inserted into a sheath that is wound with the electrical winding. The sheath is wound and cast with the electromagnetic coil assembly, and the optical fiber is slidably inserted therein. The optical fiber has a core containing at least a first Bragg grating etched therein. The method further includes detecting a wavelength of light reflected from the first Bragg grating and determining a temperature of the electromagnetic coil assembly at a location of the first Bragg grating utilizing the detected wavelength of the light reflected from the first Bragg grating.

    摘要: A lighting system has a heat sink for removing the heat released by LED chips by means of natural convection and thermal radiation. A center opening formed between air and heat sink fins enables the transfer of heat generated by LEDs, electronic driver circuit and phosphor on said heat sink fins to the flowing air inside and removing from the system, and increases the contact surface of heat sink fins with the air that enables to transfer the heat effectively from heat sink fins to flowing air and also with effective radiative heat transfer. The heat sink has a chimney inlet where air enters into said center opening, on which the PCB and said LED package are positioned, and which interconnects LED package and heat sink, which has an optimized structure and base angle, that maximize the heat removal by natural convection and thermal radiation.
