In Los Angeles (California, USA) completed usai lighting the first phase of a large-scale usai lighting project to translate street lighting with sodium discharge lamps to LED light sources (LED). A total of 141,089 modified light district! What benefits will municipality and residents of this initiative?
LED Lighting in Los Angeles (here and below the picture Bureau urban street lighting). First of all - saving energy. It is estimated that street usai lighting lighting accounts for up to 40% of the total costs of state agencies on electricity costs. Besides the issue of budget spending, there is an environmental issue: because of the generation of electricity in the atmosphere tens of millions of tons of harmful substances. Rejection of sodium discharge lamps in favor of LED-emitters can reduce energy usai lighting consumption by 40%. Moreover, in practice, usai lighting depending on the operating conditions savings usai lighting can be even more impressive - up to 63%. In monetary terms, LED bulbs will save the City Hall every year at least $ 7 million budget. Another important factor - the frequency of service. The service life of LED-emitters is equal to an average of 10-15 years. Sodium vapor lamps "live" much less - about 4-6 years. Thus, the transition to LED technology reduces maintenance costs and reduce the number of technicians. usai lighting And this is - $ 2.5 million annual savings.
One of the city streets usai lighting to the introduction of LED-lighting ... LED-lamps provide higher brightness and have better color reproduction characteristics. usai lighting Furthermore, color hue and color rendering index can be adjusted by selecting the lamp for a particular application. But what is the price? The cost of LED lamps are often significantly higher than traditional lighting. But in view of the fact that the replacement usai lighting of bulbs in street usai lighting lights associated with significant costs and require usai lighting special equipment, the use of LED-sources provides considerable savings in the short term. In addition, LED-lights constantly getting cheaper. Thus, in 2009, the cost of such a street lamp was on average $ 432, then at the end of 2012-th - $ 245. In this case, the service life increased from 80 to 150 thousand hours, and manufacturer's warranty - 5 to 7 years. In the second phase of the project to modernize the lighting Los Angeles led lights will appear in the 70 th decorative streetlights.
And ... after. Program for the introduction of LED street lighting realize many other American and European cities. For example, a Los Angeles-based colleagues agree completely Perridzho Tom (Tom Perrigo), head of the Las Vegas Strip Development, who said that you can save more than 60% of electricity by installing in LED light sources. Read also about the "smart" system of street lighting Tvilight, able to automatically usai lighting change the intensity of the glow lamps, depending on the current situation. usai lighting Prepared according to Forbes.
