What is the luminous flux of 250W and 400W high pressure sodium lamps? Would you like to replace them with 120 180W LED street lamps?
Calculate the light efficiency of high pressure sodium lamp will know, the luminous efficiency of high pressure sodium lamp is 70 80lm/w, and 06 - 0.7 use factors come to the conclusion that, the number of alternative to LED street light in your view that "
When the high pressure sodium lamp is used, the golden colored light is generated, and the utility model has the advantages of high luminous efficiency, low power consumption, long service life, strong fog permeability, no insect trapping, etc.. Widely used in roads, highways, airports, docks, docks, stations, plazas, street junctions, industrial and mining enterprises, parks, courtyards, lighting and plant cultivation. High color high pressure sodium lamp is mainly used in stadiums, exhibition halls, casinos, department stores and hotels and other places lighting.
At present, the light efficiency of high-pressure sodium lamp is generally 70 - 80lm/w, plus the use of factors 06 - 0.7, we can draw a conclusion.How many substitutes for a LED street light will depend on your light effects.
