We will optimize your lighting and illumination systems
As much as we as an engineering firm are concerned, Illumination Engineering is the branch of engineering concerned with the use of radiant energy containing visible wavelengths (light). Illumination engineering investigates principles and develops methods for generating and spatially redistributing light, measuring light characteristics, and converting light into other forms of energy. It also deals with the technological development, setting of standards and design of light sources, lighting, irradiating, and signaling instruments, devices and systems, as well as control systems for light sources. In illumination engineering, installations of lighting devices are classified according to the field of light utilization as lighting, irradiation, signaling and motion picture & projection systems. We have dedicated optical engineers specialized in these areas. Using advanced software tools such as Zemax and Code V and many years of experience in optical design and development we are able to help you in any challenges you may have in the field of illumination. Here are the specific areas of illumination engineering we specialize in:
Lighting installations provide the necessary conditions for visual reception (seeing), through which man receives approximately 90 percent of the information about his physical surroundings. Therefore the importance of this field in engineering is obvious. In architecture and design, illumination engineering is concerned with the propagation and distribution of the radiant energy of the sun as well as from artificial sources containing visible wavelengths in buildings and outdoor premises. Our illumination engineers have also in-depth knowledge on the optical properties of building materials and structures, the effect of light on visual perception in the interiors of buildings, and the aesthetic function of light in the architecture of public buildings, squares, and architectural complexes. Engineering calculations need to take into account the required level of lighting in work areas. Our illumination engineers perform theoretical calculations based on established physical parameters and through evaluations of the characteristics of rooms with the aid of models. Our illumination engineers also conduct laboratory tests of light-transmitting building materials and structural components of windows, skylights, and sun-screening units, and conduct observations and measurements at the structures themselves. We use photometric, and in particular colorimetric techniques. Specially designed photometric sphere are used, with a model of the natural sky on the inner surface, and a light-receiving chamber. The sample being tested is mounted in an aperture of the chamber. Illumination engineering work for lighting applications can be found widely in modern cities, industrial buildings, factories, picture galleries, museums, monuments, exhibition pavilions…etc. Illuminating engineering has great importance for lighting systems in production environments because optimal quantitative and qualitative lighting characteristics increase labor productivity and the quality of work. Lighting also contributes to productivity in animal husbandry and horticulture. Lighting standards take into account the complex ways in which the light and color environment affects architectural and aesthetic sensibilities and the efficiency, productivity and health of persons. Optimization for lighting systems needs to be in accordance with requirements that determine the operational properties of buildings and the climate of rooms. This means, besides illumination engineering, we need to take into consideration heat engineering, structure strength, acoustics and more. This requires special expertise in this field, for which we are well qualified.
Irradiating installations are used to produce certain effects on humans, animals, and plants. Irradiation systems can also be used in diverse industrial processes. The irradiation of organisms by ultraviolet (UV), visible (VIS), or infrared (IR) light improves vitally important morphological and functional processes such as metabolism, sanguification, regulation of cardiovascular activity, photosynthesis..etc. Bactericidal irradiation used widely in hospitals, operating rooms, surgical facilities, pharmaceutical or food manufacturing & processing plants, water disinfection & bottling has a significant hygienic effect, killing harmful bacteria. Irradiation systems are also being used in physical therapy. Irradiation installations used in agriculture have shown significant economic results. Artificial light is used in the commercial growing of vegetables and fruits. Irradiation systems are also used in photolithography, a technique used to produce semiconductor microchips, in the drying of paint and varnish coatings, and in photochemical and other technological processes.
Signaling devices and systems are used for transmitting coded information in the form of signals produced by signaling devices such as traffic lights, lighthouses, running lights, and landing lights. Signals are received either by our eyes or by other radiation receptors, such as photoelectric cells.
Motion-Picture and Projection Systems
Another area of illumination engineering deals with the use of light in all stages of the cinematographic and projection processes. Illumination engineering in the motion-picture industry deal with the production of a film, the preparation of prints, and the projection of the finished product. In the shooting of films, illumination engineering deals with the development and application of light sources and lighting devices for illuminating the shooting process and of lighting systems and screens for special types of shooting (special effects), the parameters of light sources and lighting devices, and the lighting conditions during filming, development and use of light filters and photometric apparatus for investigating the properties of photosensitive materials. Problems of film exposure and certain artistic and creative problems encountered in filming under certain environmental conditions such as fog or underwater, can be resolved by the methods of illumination engineering. In film printing, illumination engineering deals with the development of lighting systems and photometric instruments for motion-picture film printers. Our well-versed optical design and test engineers are a perfect fit for any motion-picture and projection system application.
