Given the importance of lighting and lighting calculations that are often overlooked in our country decided to offer a series of articles to colleagues and friends wishing to become familiar with this important issue to apply. Light flux: the light emitted from a light source in all directions in space at the same time the light flux say. Light flux unit "lumen" is the Lm show. In terms of lighting calculations, the luminous flux (Φ) show. View the full light of the lamp and the lamp manufacturer will be included in the Catalogue. So the flux of light a bulb is brighter than the bulb. The point that must be considered in the light flux is the number of optical flux profile along the tube inserted in the light flux of the lamp, most of the light bulbs are after the slows flux of a of the passage lifes, The light flux decline due to fatigue and reduced efficiency of the various components making up the building, such as the fluorescent lamps, norveski radijatori gas chamber, tungsten filament evaporation and more. Thus, the stability of the optical flux at the beginning and end of lamp life is an advantage during the preparation of the lamp should be noted. norveski radijatori For example, the luminous flux of the lamp current to have a better understanding norveski radijatori of the optical flux is noticed: inflammatory norveski radijatori lamps (conventional incandescent lamps) .................... 100 W ............ standard 36-watt fluorescent lamp lumens 1360 ............................... .................... ..................... 70 watt 2300 lumen lamp Metal Halayd two heads ........................................ 6500 lumens brightness (Illuminance): the amount of flux the optical unit area (1 m) is the intensity (E) is called lighting and lighting calculations is one of the important parameters. Lux is the intensity of the show. Average brightness level, the luminous flux per unit area: Lux = Lumen / m brightness in the calculation of the amount required in the light intensity is determined according to standard tables. The intensity of each table space is based on the type of activity that occur in the environment and the accuracy is determined. For example, according to intensity required for the repair of small parts such as repair shops and h ... 500 lux brightness and 200 to 300 lux for office lighting, and the little traffic warehouse or parking 50 deluxe sufficient is. So Simply optical flux of the light from the lamp is removed, and the brightness, the amount of light emitted by the light and reflect different after finally reaches the surface. There are tables that have been developed by the standards organizations and the local illumination intensity required is determined norveski radijatori by the tables. Should be pointed out that international standards often can not be used because the light is largely cultural characteristics and interests of the people associated. Light intensity norveski radijatori (Luminous Intensity): The luminous flux emitted per unit of angular space with the intensity (I) show. In other words, a lamp luminous flux in all directions and with different strength and weakness emits the light spread in a particular direction in the space of light intensity norveski radijatori or say, and the same Candela (cd) or candle. Since the reflector lamps emit light in a particular direction in space (such as halogen reflector lamps) To mention the amount of light emitted from the lamp unit used Candela. So obviously, for the lamp with the same characteristics quite similar, only with different angles of the reflector, norveski radijatori the reflector angle is smaller than most, because virtually all of the light intensity of light flux emitted by the lamp in the smaller the angle focus Therefore, the light intensity increases. For a curved reflector light bulb inserted into the Arctic as part of the profile, indicating the intensity of light at different angles and lighting design must be used. The first part of
