When used, high-pressure sodium lamps emit a golden-white light, featuring high luminous efficiency, low power consumption, long lifespan, strong fog penetration ability and corrosion resistance. The high-pressure sodium lamps made of niobium-zirconium alloy are the third-generation new type of electric light sources. Usually, niobium-zirconium alloy is used. The niobium-zirconium processing materials (Nb-1Zr alloy tubes or Nb-1Zr alloy wires), although their proportion in high-pressure sodium lamps is relatively small, directly affect the stability and lifespan of the lamps. During the lighting process of the lamps, the niobium-zirconium alloy relies on its good arc starting performance, corrosion resistance, high strength at high temperatures and good processing performance.
High Intensity Discharge Lamp, abbreviated as HID, is a gas discharge lamp that generates arc light through the activation of xenon gas by high voltage current. It consists of a lamp head, an electronic rectifier (stabilizer), and a wiring group, and requires a light intensifier to achieve a stable working voltage.
It is mainly used in automotive headlights, motorcycle lighting, household and commercial lighting, street lighting, and other fields.
