The high-pressure sodium lamp, like other gas discharge bulbs, works in the arc discharge state, with the negative slope of the volt - ampere characteristic curve, that is, the bulb current rises, while the bulb voltage drops.Under the condition of constant power, in order to guarantee the stability of the light bulb, series circuits must be a positive resistance characteristic of circuit components to balance the negative resistance characteristics of stable working current and the element called ballast or current limiter.The high pressure sodium lamp is used to emit gold and white light. It has the advantages of high luminous efficiency, low power consumption, long service life, strong ability to penetrate fog, and not to attract insects.It is widely used in road, expressway, airport, dock, dock, station, square, street intersection, industrial and mining enterprise, park, courtyard lighting and plant cultivation.The high color high pressure sodium lamp is mainly used for lighting in gymnasium, exhibition hall, entertainment field, department store and hotel.Road Lighting Series,Road Lighting,Road Lighting Decoration,Road Lighting Book High Power LED Street Lamp,Led Street Lamp,Led Street Lamp Bulbs,Led Street Lamp Price
