Regarding to the high price and low market popularity of current LED indoor lighting products, a LED indoor lighting platform is proposed based on Web3D technology. The internet virtual reality technology is integrated and applied into the LED collaborative ecommerce website with Virtools. According to the characteristics of the LED indoor lighting products, this paper introduced the method to ...
This paper presents the performance of solar cells under different electric lighting sources in indoor environments. Experiments are conducted for different solar technologies like polycrystalline Silicon, Amorphous Silicon and DyeSensitized .Measurements are done under illumination from incandescent, fluorescent and LED light sources in this paper. Also, simulations are done to find out the ma...
A novel sustainable source was developed for an existing Italian lighthouse, exploiting the light emitting diode (LED) technology and the norms evolution. The research work started with the optical design of the device, while this work concerns the realization, installation, and test of the new LED lamp. The lamp recombines multiple separated LEDs, realizing a quasipunctual localized source. Af...
The paper describes the development and application of several techniques for knowledge extraction from trained ANN models, such as the identification of redundant inputs and hidden neurons, deriving of causal relationships between inputs and outputs, and analysis of the hidden neuron behavior in classification ANN. Example of the application of these techniques is given of the faulty LED displ...
A Two-metric Proposal to Specify the Color-rendering Properties of Light Sources for Retail Lighting
Lighting plays an important role in supporting retail operations, from attracting customers, to enabling the evaluation of merchandise, to facilitating the completion of the sale. Lighting also contributes to the identity, comfort, and visual quality of a retail store. With the increasing availability and quality of white LEDs, retail lighting specifiers are now considering LED lighting in stor...
Light emitting diodes (LEDs) and SSL (solid state lighting) are relatively new light sources, but are already widely applied for outdoor lighting. Despite this, there is little available information allowing planners and designers to evaluate and weigh different sustainability aspects of LED/SSL lighting when making decisions. Based on a literature review, this paper proposes a framework of sus...
Economic growth is a macroeconomic variable that always the government's attention. This because economic an indicator of country's performance. If grows high, then development goes well, so people are more prosperous. study aims to examine and analyze role FDI exports on in ASEAN. The research method used causality panel with period 2010-2020. this detects how relationship between FDI, exports...
