What is the luminous efficiency of high pressure sodium lamp?
High pressure sodium lampLuminous efficiency 90~130Color rendering 30~60Yellow light, fog goodSmall, often used in street lamps, industrial and mining lightsLow pressure sodium lampLuminous efficiency 130~170Color rendering 10~30Yellow light with excellent fogging,Large, often used in tunnels, mines, lamps
The average luminous efficiency of sodium light is 130 lumens per wattIn general, high pressure sodium lamp is mainly used in the street lightsThe main I features are: yellow light penetration is better, foggy weather or better resultsThe average color rendering index is about 50, which belongs to a relatively poor kindHigh pressure sodium lamp generally power is relatively large, suitable for industrial lighting
High pressure sodium lamp has the advantages of high luminous efficiency, low power consumption, long service life, high fog resistance and no lure. 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.
High pressure sodium light effect 90~130, color 30~60 yellow light, fog good, small size, more used for street lamps, industrial and mining lights.
