The use of light emitting diodes (LEDs) for lighting requires high level of thermal management. In fact, the lamp is more efficient when operating under lower junction temperature. In this paper, we present a three dimensional analysis of 106 W multi-chip LEDs lamp using finite element method. A comparison between two different substrate designs was carried out and showed that using separated substrates (an individual substrate for each chip) ameliorates the heat transfer rate more than the case of using one continuous substrate for all chips. The design of separated substrates was then optimized taking into account the substrate dimension, the spacing between adjacent chips and the number of chips on each substrate. It was found that using the optimal design of separated substrates instead of continuous one leads to a decrease of 14.38% of the junction temperature, an amelioration of 11.82% of the light output and an augmentation of 105212 hours in the lamp lifetime.

We report a methodological approach for simulating luminary output radiation, which is achieved by mixing light-emitting diodes (LEDs) in order to match any plant absorption spectrum. Various recorded narrow-band LED spectra of different colors were first characterized and then fitted with a multi-Gaussian model. An optimizing procedure computed the optimal weighting of the relevant parameters so as to minimize the discrepancy between the combined spectrum and the reference target curve. The particle swarm optimization (PSO) method was applied because it is the most suitable technique for mono-objective situations. Within the useful spectral interval, the worst relative standard deviation between the optimized curve and recorded LED spectral power distribution (SPD) was 3.4%. When combining different LED types, the simulated light output showed that we could limit ourselves to selecting only five colored sources. This work will help us to design an optimized 200 W laboratory luminaire with a pulse-width switched-mode power supply.

In this work, a new flexible antenna integrated with OLED light sources is presented for WiMAX wireless communication systems. The proposed antenna was placed on a 100% polyester base with a thickness of 1.5 mm and achieved a high gain. We evaluated and tested its performance, including reflection coefficient, radiation pattern and gain. The flexible and simple patch antenna has been designed to operate at 3.5 GHz for WiMAX wireless communication systems with a gain value of 5.38 dB. This article proves the applicability of the proposed material for the integration of flexible antennas in OLEDs while maintaining gain performance similar to conventional flat antennas.

The system under calibration has been previously characterized in photopic conditions. Due to increased interests in mesopic conditions, it was adapted to be usable in such an environment. Preliminary tests raised concerns about the stability of the generated stimulus. This paper retraces the steps which were consequently applied to fully capture, analyze and comprehend the source of observed stimulus instabilities. Through statistical analysis of the numerical results, some hypotheses were dismissed. The purpose of this paper is to expose a rigorous methodology in order to establish a well-controlled experimental environment.

In this study, we present a new transparent flexible coplanar waveguide (CPW) bandpass filter using polyethylene terephthalate (PET) substrate while the simulation results permit to characterize the filter in terms of bandwidth, S-parameters, and current distribution. The resonator of the filter is implemented using a special compact square ring resonator patterned in the central conductor of a CPW transmission line. The impedance bandwidth of the proposed bandpass filter in the lower and higher frequency bands are 5.4% (10.3 to 10.87 GHz) and 11.2% (12.7 to 14.2 GHz) respectively, making this transparent filter suitable for dual-band X and Ku bands applications. Due to its foldable, bendable and transparent qualities, this filter can easily be integrated together with an OLED light source.

The luminance degradation studies of OLEDs light sources under thermal and electrical stress conditions are normally achieved in order to estimate the OLEDs lifetime. In this study, the colorimetric parameters have been measured and calculated at different durations to understand the behaviour of OLED’s spectral distribution power over time. The spectral quantities of the studied OLEDs were measured using a MINOLTA-CS-1000 spectroradiometer, these measurement were treated afterwards in the “ANSI-IES TM-30-18 Basic Calculation Excel Tool”. Results shows that not all the OLED colorimetric parameters know a deterioration in terms of visual comfort when submitted to stress conditions.

Diffuse reflectance spectroscopy (DRS) is a technique that illuminates the surface of the tissue and analyzes the spectrum of backscattered light, in which the signature of various biochemical species can be identified. This promising technique is established in this article for the non-invasive and in vivo characterization of the optical properties of tissues for diagnostic applications. We have introduced a new compact and inexpensive architecture for DRS based on the use of a multispectral image sensor and LEDs to obtain a diffuse reflectance signal in contact with the skin. For the proof of concept, a prototype device, involving a spectrometer coupled to an optical fiber, a microcontroller, a set of 8 LEDs and a computer, was developed, manufactured and set up. Diffuse reflectance profiles were acquired at 438.2 nm, 544.5 nm and 613.7 nm. Indeed, the spectrum of Mycobacterium ulcerans was established by this method at 256 nm and 365.2 nm. The results obtained confirm the potential of our approach for the quantitative characterization of the optical properties of tissues.

In this paper, a new concept of an optically transparent antenna integrated in OLED (Organic Light Emitting Diodes) is proposed for the 5G mobile applications. This proposed antenna is designed for future millimeter-wave (mm-Wave) 5G applications. The proposed optically transparent antenna is a network of micrometric hexagonal cells deposited on a glass substrate. By using this hexagonal geometry, we obtained a theoretical optical transparency of about 920%. This antenna can cover the 28 GHz band from 27.43 GHz to 28.88 GHz with a width of 1.45 GHz. The suggested design has a gain and directivity about 5.07 dB and 6.27 dBi at 28.27 GHz, respectively.

A new flexible antenna made entirely from a transparent conductive fabric VeilShield has been designed to be integrated in OLED light sources as well as flexible or rollable displays. It was layered on a 100% polyester support with a thickness of 1.5 mm and achieves a good adaptation and high gain. The simple and flexible patch antenna has been designed to operate at two frequencies bands: the first one operating at 3.15 GHz in S-band and the second operating at 3.5 GHz for WiMAX wireless communication systems. We have evaluated and tested its performances, including the reflection coefficient, the gain, the radiation pattern and the surface current distribution, with gain values of 5.76 dB and 1.66 dB respectively. This article demonstrates the applicability of the material proposed for the design of flexible antennas integrated into OLED light sources while maintaining gain performance comparable to conventional planar antennas.

Blue light effect on the human circadian cycle is not considered in a wide available lighting systems product on the market. The blue part of the white light received by a human act as a switch for the production of the melatonin by the pineal gland and can disrupt the sleeping period. The photopigment so called Melanopsin is responsible of transmitting the information “day or night” to the SCN (Suprachiasmatic Nucleus) and is sensitive to light at a bandwidth wavelength around 420 nm to 560 nm with a maximum sensitivity at 480 nm, meaning that a light source containing a significant proportion of blue light will stimulate this photopigment and then will suppress melatonin production. The link between the appearance of white light (warm, neutral or cold) and how it affects sleep in humans is generally misinterpreted. This is because at sunset, the spectral distribution of the sunlight contains a low amount of “melanopic light” (light spectrum for melatonin suppression for humans with a peak around 490 nm) and therefore does not cause a high melatonin suppression. Thus, it is commonly assumed that orange light does not affect the regulation of the biological clock. This applies only to sunlight, as well as, to blackbody emitters and not for all artificial lighting systems and in particular for LED (Light Emitting Diode) sources. Contrary to general accepted ideas, our results suggest that it is possible to create a combination of RGB LED components simulating warm white with high Melanopic Efficiency Factor (MEF), which involves the activation of melanopsin and, thus suppress the melatonin production.

In this paper a tunable Light Emitting Diodes' (LEDs) spectrum is proposed to match the plant's spectrum based on the relative quantum efficiency (RQE), proposed by McCree as a reference curve. Various LED spectra with different peak wavelengths are combined into a single one, in order to match the reference target spectrum. Based on optical and electrical experiments, nearly monochromatic LED spectra are measured. A multi-Gaussian function is adopted in order to model the best fitting of the different LED's spectrum. Three different kinds of LED combinations are proposed in order to achieve the optimal spectrum for plants. MATLAB simulation is used to show the matching of LEDs using the proposed LED combinations.

Measurement of reflectance properties of asphalt is an insufficiently addressed problem, although this parameter is involved in three major directions in which the development of roads and lighting takes place: new technologies for materials, including solar energy harvesting, energy efficiency of road lighting and light pollution reduction. For each of these directions, concerns for improving performance have been identified, in which for each percentage gained, significant efforts and costs are registered. It is thus shown that although the reflectance properties of asphalt can change the results to a large extent (even 47%), this parameter is considered as a material constant and is not measured, although it is variable over time. After evaluating some landmarks regarding the geometric domain for which this parameter must be measured, a photographic method is presented and exemplified by which the desired values can be obtained insitu conditions.

The high electricity bills of houses have triggered a significant research for solutions to mitigate this issue. The house automation systems offer everything necessary to put an end to these inconveniences as, most often, they incorporate a number of smart devices (microcontrollers and sensors). The presented work outlines the development of a microcontroller-based automation system of a solar smart house using automatic lighting and thermal comfort sensors (temperature, humidity) and safety functions (gas leakage, smoke detection). This system is based on PIC microcontrollers and is applied through the implementation of a complete algorithm. The program is written on Micro C, and in order to realize the control circuit and the simulation, the testing software made use of Proteus software which is freely available from the Internet. The control of temperature and air pollution was implemented using the PIC16F877A, while the light control was applied with the PIC18F4550. The hardware prototype was also provided to experiment on the designed control strategy. The results of this work allowed some conclusions to be reached and confirmed the benefits of this kind of automation systems.

Because of the absence of lighting calculation tools at the initial stage of tunnel design, the lighting systems are usually over-dimensioned, leading to over illumination and increased energy consumption. For this reason, a fine-tuning method for switching lighting stages according to the traffic weighted L20 luminance is proposed at no additional cost. The method was applied in a real –case scenario, where L20 luminance of the access zone at eleven (11) existing tunnels was calculated. The traffic weighted method of CR14380 was used in order to calculate the actual luminance levels for the entrance zone. The new transition zone, which decreases luminance curves, was produced and compared with the existing ones. Thus, a new switching control was proposed and programed for the Supervisory Control and Data Acquisition (SCADA) system of the tunnel. The signals of the corresponding eleven L20 meters for a period of eight days were used and the corresponding annual energy consumptions were calculated using the proposed switching program for each tunnel. The results were compared with a number of scenarios in which the existing lighting system was retrofitted with Lighting Emitting Diodes (LED) luminaires. In these scenarios, the new luminaire arrangement was based not only on the existing luminance demand value for the threshold zone, but also on the newly proposed one with two different control techniques (continuous dimming and 10% step dimming). The fine-tuning method for switching resulted in energy savings between 11% and 54% depending on the tunnel when the scenario of the existing installation at no extra cost was used. Energy savings, when LED luminaires were installed, varied between 57% (for the scenario with existing luminance demand value for the threshold zone and 10% step dimming) and 85% (for the scenario with the new calculated luminance demand and continuous dimming).

In the context of an aging population, it is important today to take into account the needs of our seniors, to help them better live their aging. The design of colour and lighting ambiance contributes in the practice of their daily activities in their living environment. This study postulates a protocol of good practices in terms of colour and lighting to design a visual environment adapted to the needs of these users. The protocol is based on a combination of chromatic and lighting expertise. Chromatic colour matching based on Natural Colour System tools is combined with a photometric survey to characterize the visual environment. These data make it possible to establish a protocol used to design new chromatic ranges applied to new environments or to evaluate the applicability of the existing ranges.
