Abstract:

This article discusses the possibility of reducing the dimensions of ultraviolet and infrared radiation devices through the use of more compact infrared lamps, evaluates the quality indicators of halogen lamps by the method of analysis of variance. The parameters of the lamps were measured in the measuring laboratory of SSZ Lisma LLC during the service life: at the beginning of operation and then after 1800 and 3750 hours. Samples of five pieces were taken from batches of lamps. The main analyzed parameter was the correlated color temperature. The test protocols for the studied lamps are presented. The analysis carried out indicates, in general, the stability of quality indicators when comparing two types of lamps during their service life, which suggests the possibility of their use in irradiators for infrared heating of animals. In the course of the work, recommendations were given on the development of a small-sized combined irradiator using a lamp of the KGT 220-600 type.

Abstract:

This study was conducted to develop an accurate quality evaluation system based on optimized factors such as light source array and light power, which are used in non-destructive fruit sorter to obtain the internal quality information of fruits using the near infrared transmittance spectra. It is necessary to provide the proper design guide for the light source part in the existing non-destructive fruit sorters for apples and pears, and to measure the real-time near infrared transmittance spectrum without the leakage of light. The near infrared transmittance spectrum detection system was developed with the light source part which has the power-controllable 12 halogen lamps (100W/12V) with gold coating, light detection part, and transfer line. By using the accurate control of the voltage and current (maximum power is 1.2kW) in light power control part, it is concluded that the minimum power for the internal quality evaluation of apples and pears was over 0.5 kW. To prevent the leakage of light, the array of light source was rearranged and tested. Without changing the tray structure, it is concluded that the leakage of light can be prevented by the proper array of light source and power. For the irradiation for the moving apples and pears, 2 upper lamps and 4 lower lamps combination did not have leakage of light and the correlation coefficient of this combination shows the 0.90 for apples and 0.96 for pears.

Abstract:

PET prefom surface temperature distribution is a key factor for getting the better quality of construction a bottle by stretch blow molding (SBM) machine. To get a better temperature distribution, different types of prefom under different number of infrared lamps heating conditions are worth to investigate the position of each lamp as well as its power intensity. In this study, we first try to use adaptive finite volume method to estimate the proper intensity of each lamp so that the combination strength will make good result about the temperature distribution. Then we make experiments to confirm each case. We have five, six, and seven heating lamps cases to present. With these estimations, we find that five lamps case can do equal quality about the temperature distribution comparing with six and seven lamps cases. This means that we offer a method for finding one saving energy way to produce PET bottle by SBM machine. A more detail analysis about inside PET bottle temperature distribution will be deliberated in future.

Abstract:

In this study, the effectiveness and feasibility of a flame detector using a 4-wavelength infrared sensor that can compensate for the non-fire alarm disadvantages of the existing infrared flame detector was analyzed. The proposed flame detector adds an additional infrared sensor to the existing flame detector that uses two or three infrared sensors. The information from the additional sensor was used to determine non-fire alarms. To determine the fire/non-fire, wavelength information of the flame emitted from the fire source is required. To obtain this wavelength information, various fire sources, such as halogen lamps, spectrum analysis, fan heaters, and arc welding, were analyzed. To analyze the wavelength characteristics of each fire source, spectrum analysis (fast fourier transform, FFT) of wavelengths was performed in the central processing unit (CPU) of the flame detector, and the intensity of each wavelength was measured. Additionally, two wavelengths (3.95 μm and 5.3 μm) were used to discriminate non-fire alarms, and the parameters for judging fire/non-fire more accurately were derived using the information on these two wavelengths. To confirm the operation characteristics of the 4-wavelength infrared sensor flame detector, a fire test was performed using n-heptane. The results of the experiment indicate that the fire signal was generated accurately in the fire source experiment using n-heptane, and the non-fire alarm could be accurately identified in the non-fire source experiment of halogen lamps, fan heaters, and arc welding.

Abstract:

Light-emitting diodes (LEDs) are a potential irradiation source for intensive plant culture systems and photobiological research. They have small size, low mass, a long functional life, and narrow spectral output. In this study, we measured the growth and dry matter partitioning of `Hungarian Wax' pepper (Capsicum annum L.) plants grown under red LEDs compared with similar plants grown under red LEDs with supplemental blue or far-red radiation or under broad spectrum metal halide (MH) lamps. Additionally, we describe the thermal and spectra1 characteristics of these sources. The LEDs used in this study had a narrow bandwidth at half peak height (25 nm) and a focused maximum spectral output at 660 nm for the red and 735 nm for the far-red. Near infrared radiation (800 to 3000 nm) was below detection and thermal infrared radiation (3000 to 50,000 nm) was lower in the LEDs compared to the MH source. Although the red to far-red ratio varied considerably, the calculated phytochrome photostationary state (φ) was only slightly different between the radiation sources. Plant biomass was reduced when peppers were grown under red LEDs in the absence of blue wavelengths compared to plants grown under supplemental blue fluorescent lamps or MH lamps. The addition of far-red radiation resulted in taller plants with greater stem mass than red LEDs alone. There were fewer leaves under red or red plus far-red radiation than with lamps producing blue wavelengths. These results indicate that red LEDs may be suitable, in proper combination with other wavelengths of light, for the culture of plants in tightly controlled environments such as space-based plant culture systems.

Abstract:

We report the single-crystal growth of the unconventional superconductor Sr2RuO4, on which research has reached a turning point recently. In order to optimize the quality of crystals grown by the floating-zone method using an infrared image furnace, we focus on an improvement of the structure of the filament in the halogen lamps. By reducing the thickness of the total filament, the form of the molten zone was narrowed. More importantly, the molten zone was observed to be more stable during the growth process. Finally, we obtained the crystals with a length of 12 cm. Additionally, the grown crystal has high quality, displaying the 1.5 K transition temperature expected only for the purest crystals. We also discuss the availability of the newly developed halogen lamps.

Abstract:

The formation of nanocomposite Nd-Fe-B/Mo/FeCo multilayered magnet films using the infrared laser annealing technique. The perpendicular magnetic anisotropy of the film with Mo interlayer was larger than that of the film without Mo interlayer before annealing. Magnetic properties of both films were drasticly changed from soft magnetism to hard magnetism with in-plane magnetic anisotropy after the infrared laser annealing process at 760°C. Coercivity of in-plane annealed film with Mo interlayer was about 10 kOe which was double that of the film without Mo interlayer. In second quadrant, squareness of demagnetization curve of infrared laser annealing processed film with Mo interlayer was better than that of film without Mo interlayer. The infrared laser annealing process crystallizes the amorphous phase of the Nd-Fe-B layer as well as the multi-step annealing, even though the infrared laser annealing process time is only 1/100 of the process time of the multi-step annealing using halogen lamps reported previously.

Abstract The article is devoted to the study of infrared drying of products in a reduced pressure chamber using the convection effect. With the use of drying, canning of fruits, vegetables, herbs and meat is achieved, which reduces not only the volume, but also the weight of the processed raw materials. The paper presents the main parameters of drying products online, such as relative humidity, pressure, radiation intensity of infrared lamps, drying temperature. The uniqueness of this unit in comparison with similar dryers is a one-time treatment of the product with infrared rays under reduced pressure, convection of air flows inside the drying chamber and full automation of the drying process of any product of plant and animal origin. Determination of parameters and modes of drying was carried out on products of plant origin. During the experimental part, bananas and apples were used. In experimental studies, products such as bell peppers, apples and bananas with various slicing thicknesses were used. The greatest drying effect was obtained with a drying product thickness of 5 mm, and the worst with a product thickness of 10 mm. For example, pepper has decreased in weight from 79.84 grams. up to 23.43 gr., which is his weight loss by 70.65%.

A new confocal microscope has several unique features which differentiates it from other in vivo confocal imaging systems.is described. • The light source is a halogen lamp. This source has many advantages over the mercury or xenon arc lamps used in other confocal designs. The mercury or xenon arc lamps have the problem of arc jitter which results in changing illumination intensity. Filters are inserted in the lamp housing to remove both short ultraviolet and infrared light. • The microscope uses standard microscope objectives which are readily interchangeable. Other in vivo confocal systems are limited to a built in objective which is not removable. In these studies we used a Leitz 50X, NA 1.0 water immersion objective.• The detection system consists of an intensitified video camera with video output to a Sony U-matic tape recorder. In parallel with the video recording there is a video monitor in order that the operator can observe in real-time the confocal images of the subject's eye.

Abstract:

Purpose. The paper considers peculiarities of using artificial illumination sources with effective spectral composition of radiation for conditions of closed soil. Methodology. High-intensity sodium lamps (DNaT400), high- intensity sources with composition of sodium amalgam with cesium additives were investigated (Hg-20%, Na-7 5%, Cs-5%), potassium (Hg-20%, Na-79%, K-1%). Results. As a result of experiments, it was determined that the spectral radiation composition of lamps with additives Cs, K, Rb has a lower radiation intensity compared to standard high pressure sodium lamps (DNaT) in the region of 500-600 nm and significantly higher intensity in red (600-700 nm) and near infrared regions. The physicochemical properties of the sodium-cesium-mercury system have been studied. Melting points of ternary alloys, thermodynamic properties of melts of ternary system Na-Cs-Hg and double system of Na-Hg system are determined. The parameters of batch pressures of component vapors are calculated. The composition of the discharge tube amalgam is selected, in which the ratio of sodium and mercury concentrations is close to the corresponding ratio in a standard sodium lamp, and cesium additives vary in the range from 5 to 10 atm. %. The influence of cesium content in amalgams on light and color parameters of lamps is considered. Tomatoes were used in the experiment, which were additionally illuminated with lamps DNaT400, high intensity discharge tube filled light sources (20at.% Hg, 77at.% Na, 3at.% Cs20); (20at.% Hg, 75at.% Na, 5at. % Cs); (20 at. % Hg, 73 at. % Na, 7 at. % Cs); (20 at. % Hg, 70 at. % Na, 10 at. % Cs). Originality. In the use of high-pressure sodium lamps with a filling of the discharge tube in different weight ratios of Hg, Na, Cs. Practical value. When using high-intensity light sources with additives Cs having amalgam composition (20 at.% Hg, 75 at.% Na, 5 at.% Cs), growing tomato plants in the early stages of development is most effective. The total content of chlorophyll in tomatoes when irradiated with a high- pressure sodium lamp with cesium additives is 1.4 ÷ 2.5 times higher than when irradiated. DNaT400.

Abstract:

This study aimed to determine the effects of infrared lamps on survival rates of mature and immature common sun skinks (Eutropis multifasciata) in semi-natural conditions in Quang Binh Province, Vietnam, in the cold weather. A sample size of 400 mature (28 weeks old) and 120 immature common sun skinks were used in a completely randomized design with two variables of different lighting methods: infrared and incandescent light. Suitable food and water were freely provided. Results showed that the survival rates of the mature and juvenile common sun skinks were 82.5% and 39.2% with infrared light and 30.5% and 0% with incandescent light. Compared to incandescent light, the growth of young offsprings in the first 4 weeks after birth was greater with the infrared light and the average cumulative growth weight reached 2.18 g per individualby the fourth week. With incandescent light, common sun skinks lost their weight over time and gradually died out by the third week. Thus, infrared light which can be used to warm up pens may be an effective techniquein raising common sun skinks in semi-natural conditions in Quang Binh.

Abstract:

Various electric lamp sources have been proposed for growing plants in controlled environments. Although it is desirable for any light source to provide as much photosynthetically active radiation (PAR) as possible, light spectral quality is critical in regard to plant development and morphology. Light-emitting diodes (LEDs) and microwave lamps are promising light sources that have appealing features for applications in controlled environments. Light-emitting diodes can illuminate a narrow spectrum of light, which corresponds with absorption regions of chlorophyll. The sulfur-microwave lamp uses microwave energy to excite sulfur and argon, which produces a bright, continuous broad-spectrum white light. Compared to conventional broad-spectrum sources, the microwave lamp has higher electrical efficiency, and produces limited ultraviolet and infrared radiation. Experiments were conducted with spinach to test the feasibility of using LEDs and microwave lamps for spinach production in controlled environments. Growth and development comparisons were made during 28-day growth cycles with spinach grown under LED (at various red wavelengths), microwave, cool-white fluorescent, or high-pressure sodium lamps. Plant harvests were conducted at 14, 21, and 28 days after planting. At each harvest under all broad-spectrum light sources, spinach leaf growth and photosynthetic responses were similar. Major differences were observed in terms of specific leaf area and weight between spinach plants grown under 700 and 725 nm LEDs as compared to plants grown under shorter red wavelengths.

Abstract:

Abstract In several countries, an application of general anesthesia for pain prevention during castration is discussed. A disadvantage is the prolonged recovery phase, accompanied by severe body temperature drops in piglets. Aim of this study was to investigate effects on body temperature during recovery after anesthesia. Piglets were anesthetized, castrated and placed in boxes (0.24m2) for 4h. Before, 2 and 4h after the application (0.3ml ketamine+azaperone/kg BW), rectal temperatures (RT) and skin temperatures behind the ear (ST) were measured. In a first trial, impacts of infrared lamp (250W, 50-55cm height) and number of animals per box (3 vs 6) were analyzed (n = 30). In a complementary trial, infrared lamps’ height (60 vs 70cm) and piglet age were varied (n = 27) and temperatures measured half-hourly. Differences were estimated in linear models (SAS® 9.4). Mean RT before anesthesia was 39.1±0.4°C with ranges of less than 1.9°C. After 2h, mean RT in lamp-warmed piglets increased to 40.8°C (P < 0.01), whereas in absence of lamps RT dropped to 37.3 (P < 0.001), with significant differences between groups (P < 0.001). To prevent life-threatening cooling, piglets with RT as minimal as 33.5°C were warmed immediately, so that their mean RT after 4h was not different from initial temperatures. Animal number per box caused no differences. Variation between individual RT was up to 8.2°C at 2h (first trial). Means in the second trial did not differ, but variation pattern of individual temperatures was highest after 1h (6.1°C), indicating that individual differences regarding anesthetics or external factors might occur. When lamps hung lower ST were higher after 3h (P < 0.05) and 4h (P < 0.01). RT and ST were dependent on age after 0.5h (P < 0,05, respectively) and tendentious at 1h and 2h, indicating that older piglets can rely on more distinct temperature regulation abilities and use endogenous energy resources to regain homeostasis.

Abstract:

Erythema ab igne is a localised, cutaneous condition consisting of reticulate hyperpigmentation, epidermal atrophy, and telangiectasias. It is caused by repetitive and prolonged exposure to moderate heat that is insufficient for producing burns. Currently, erythema ab igne is most commonly observed following repeated use of hot water bottles, infrared lamps and heating pads. If not properly treated, erythema ab igne can become chronic and even malignant. We report a case of erythema ab igne, successfully treated with systemic mesoglycan-based therapy, and local therapy with bioflavonoids.

Abstract:

Purpose Active infrared (IR) thermography, because of its high productivity and illustrativeness, is a promising technique in nondestructive testing (NDT). The purpose of this paper is to discuss a concept and practical implementation of a portable experimental unit intended for IR thermographic NDT of corrosion in metallic shells. Design/methodology/approach The basic theory relates to the analysis of heat conduction in a plate with rear-surface material loss subjected to pulse, thermal wave or arbitrary heating. Findings The amplitude of temperature anomalies over defects and their characteristic observation times depend on material loss, size and shape of corrosion defects. A flexible architecture of the inspection unit is proposed to include flash tubes, halogen lamps and laser-emitting diode (LED) panels as sources of stimulating thermal radiation. In particular, LED heaters might be perspective due to their narrow spectral band, which is beyond a spectral sensitivity of modern IR imagers. It has been found that the IR thermographic technique is convenient for detecting material loss of up to 15–20 per cent in uniformly painted steel shells with thickness up to 8 mm. The concept of signal-to-noise ratio has been applied to evaluate efficiency of data processing techniques, such as Fourier transform and principal component analysis. Originality/value The developed equipment and inspection guidelines can be used for detecting hidden corrosion in metallic objects, such as above-ground tanks, pipes, containers, etc.

Abstract:

Smart street light is an intelligent control of street lights to optimize the problem of power consumption of the street, late in night. Conventional street lights are being replaced by Light Emitting Diode (LED) street lighting system, which reduces the power consumption. The focus of this project is to design a system of street lights controller to provide a reduction in power consumption. The prototype was designed by using Light Dependent Resistor (LDR), Infrared sensor (IR), battery and LED. The brightness of the lamps is being controlled in this project to reduce the power consumption. The dimming of the lamps depends on the speed of object motion detected such as pedestrians, cyclists and cars. The higher speed of moving object, the greater the level of intensity. For this idea, the innovation of street lights is not quite the same as conventional street lights that are controlled by timer switch or light sensor which automatically turns light on during sunset and off during sunrise. According to the study, motion detection devices may help to save up to 40% of energy per month.

Abstract:

Infrared thermography (IRT) is a full-field, contactless technique that has been widely used for nondestructive evaluation of structural materials due to many advantages. One of the major limitations of IRT is the fuzzy edge and low contrast in the inspected images—as well as the cost of the system. An efficient image post-processing with an affordable and portable device is of great interest to the engineering society. In this study, a convenient and economical inspection system using common halogen lamps was constructed. The corresponding image-processing scheme, which includes Fourier phase analysis and specific image enhancement was developed to identify defects with sharp and clear edges and good contrast. This system was applied to localized of defects in glass-fiber-reinforced composite panels. The results showed that defects with an effective diameter as small as 5 mm can be detected with excellent image quality. As a conclusion, the developed system provides an economic alternative to traditional infrared thermography which is able to identify defects with good qualities.

Abstract:

Infrared therapy is a therapeutic tool that has the function of dilating blood vessels so that blood flow becomes smoother and the healing process of wounds or inflammation in the body is faster. The heat from infrared therapy lamps can also reduce joint or muscle pain. The purpose of this research is to design an infrared therapy device equipped with light intensity settings and a timer controlled by an android. The contribution of this research is the infrared lamp irradiation media system and has also been equipped with a safe distance of 30-70cm using the HC-SR04 sensor, then equipped with a choice of a maximum therapy time of 10-30 minutes which is used to select the length of the therapy process. In addition, it can adjust the light intensity as needed via Android which is connected via the HC-05 Bluetooth module which is enabled to regulate how much light intensity is emitted by the lamp. After carrying out the measurement process, the error value on the timer measurement is obtained from the selection of Low, Medium, and High switches, 10 minutes (1%), 15 minutes (0.6%), 30 minutes (0.3%). The distance measurements are, 10cm (10%), 20cm (2.5%), 30cm (1.6%), 40cm (0%), 50cm (4%), 60cm (1.6%), 70cm (0%).

Abstract:

Abstract. This paper presents research into a method of processing thermal images aimed at detecting and characterizing material defects, or non-uniformities, of the internal structure of materials. Active thermography was chosen as the NDT method. Hidden defects were revealed by analysing the temperature field of the tested material's front surface which was externally excited with heating lamps. Background removal and image segmentation were applied to the last thermogram in the sequence recorded at the end of the heating phase. The paper focuses on the quality of determining lateral dimensions of subsurface flaws in a polymethylmethacrylate slab with bottom holes drilled to imitate flaws. The following accuracy-affecting factors were taken into account: defect depth, emissivity of the inspected surface as an input, user-set parameter for the IR camera, type of filtering used to eliminate the effect of non-uniformity when heating the object surface with an external source, and global and local thresholding as a segmentation method used for defect detection and sizing.

Abstract:

The spectroscopically important performance capabilities of a linear charge-coupled device detector system, along with the methods used to evaluate the detector performance, are described. The linearity, read noise, full-well capacity, charge transfer efficiency, and ultraviolet to near-infrared quantum efficiency of the detector are presented along with the methods required to operate the detector in unconventional modes allowing low noise and antiblooming operation. With the antiblooming mode of operation, the detector performance is shown to be unaffected by light overloads hundreds of times over the saturation level. The performance of the detector for high-resolution diagnostic studies of hollow cathode lamps as well as for molecular fluorescence is presented.
