Question
Which lens is used in sodium reflector lamp
?ÂSolution
Convex mirrors are used as reflectors in sodium reflector lamps because they are able to spread the light over a wide area. The neon gas lights at a lower temperature. As the temperature increases the sodium begins to vaporize and the lamp turns to a pure yellow. Argon has a lower glow voltage, argon helps the smaller lamps start at a lower voltage. The larger LPS lamps used in street lighting for the most part do not use argon.Â
