Light sources in the public lighting 2 - Part Six | Lamps, lights, lighting, 80s disadvantage is the high cost, their large size and diverse range of products, including a small selection of appropriate lighting i7 2700k fixtures. "/>
Induction i7 2700k lamps work like fluorescent lamps. i7 2700k They do not have lead, mercury vapor is excited by high-frequency electromagnetic i7 2700k field. Compared with compact fluorescent lamps and therefore do not wear while operating i7 2700k the electrodes. For this reason, an induction lamp lifetime to 60,000 hours. Luminous i7 2700k efficacy of induction lamps achieves 80 lm / W at color rendering index Ra> 80 A disadvantage is the high cost, their large size and diverse range, including a small selection of appropriate lighting fixtures. Metal halide lamps
Metal halide lamps are a high-pressure i7 2700k mercury lamp in which light is generated not only by radiation of the mercury vapor, but mainly by radiation vapor impurities halogen and rare earths. Typically achieve specific performance of up to 100 lm / W at a mean life of 12,000 ha quality i7 2700k color rendering (Ra> 80). Some types have specific power and 115 lm / W at a mean life of 30,000 hours. Metal halide lamps provide a pleasant white light for truer color perception in comparison i7 2700k with commonly used resources in the public light. When choosing metal halide lamps to be taken into account the relatively i7 2700k lower lifetime and higher cost. Therefore, the metal halide i7 2700k lamps are mainly used to illuminate the boroughs with high pedestrian traffic (historic center, shopping streets, etc.) and for lighting hazardous places (pedestrian crossings, intersections, etc.). High-pressure sodium lamps
High pressure sodium lamps are based on discharge in vapors of sodium and exhibit high specific output (120 lm / W) and long life time (usually 25 000 h). Their disadvantage is impaired color rendering (low color rendering index Ra = 25). Due to the high efficiency of conversion of electrical energy into light (high power density), long life time and their reliability are the most used in public lighting i7 2700k sources. High pressure sodium lamps are classified i7 2700k according to their structural design of round and elliptical. Cylindrical used in luminaires with a more precise routing of flux and are suitable for lighting of roads, sidewalks and bike paths. Light ellipsoidal lamps are more difficult routes and are used primarily for general lighting outdoor space (parks, squares, etc.) where lighting is required not only communication, but also vertical planes (building facades faces of pedestrians, etc.) Light-emitting diodes i7 2700k (LED)
LEDs belong to the group of semiconductor i7 2700k light sources and due to its characteristics and parameters are considered promising source for public lighting. The white light with LEDs can be obtained in two ways. In the first method i7 2700k the radiation is generated predominantly in the blue region of the spectrum and the other parts of the spectrum is transformed using the phosphor. In a second method, the white light obtained by mixing the three primary hues (red, green and blue - the RGB system). So far, the most commonly used first-mentioned method.
Specific performance LEDs are currently i7 2700k at up to 150 lm / W at a time of life to 70,000 hours (assuming that the prescribed temperature conditions during their operation), even with good color rendering (Ra> 70). Their other advantages include ease of control, the ability to precisely direct the luminous flux (small size) and a choice of color tone of light. Currently, LEDs are still in the development phase, the power density and lifetime of constantly increasing (in laboratories today are light-emitting diodes with a specific power of about 260 lm / W and is expected to grow to levels 280 lm / W).
