Multiobjective optimal design of Light Emitting Diode (LED) lightings
In this paper, a Pareto multiobjective optimization is performed to design new luminaires, finding the optimal forward current, number of LEDs and proper heatsink by taking into account the cost, the energy consumption and the impact on the environment (life cycle analysis from cradle to grave). Three commercialized white LEDs have been studied and modelled in terms of optical, electrical, ther...
متن کاملA low-power, LED-based, high-brightness anomaloscope
Color matches made with a Nagel anomaloscope are used in the differentiation of color vision deficiencies. When these color matches are made over a wide range of retinal illuminances, the changes in the color match provide information about the regeneration kinetics and the absorption spectra of the middle- and long-wavelength cone photopigments. These steady-state color matches vary with a var...
متن کاملLED brightness control for video display application
The technique is suggested for a kind of pulse-width-modulation LED dimming in LED video displays. The significant increase of the gray levels number and image refresh frequency can be achieved when the large number of LEDs is controlled serially. The need for a large number of grayscale levels and high refresh rate is explained. The controlling data flow and the amount of buffer memory are the...
متن کاملTraffic congestion control using Smartphone sensors based on IoT Technology
Traffic congestion in road networks is one of the main issues to be addressed, also vehicle traffic congestion and monitoring has become one of the critical issues in road transport. With the help of Intelligent Transportation System (ITS), current information of traffic can be used by control room to improve the traffic efficiency. The suggested system utilize technologies for real-time collect...
