China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Light source of visible light produced by sodium vapor discharge. low-pressure sodium lamp and high pressure sodium lamp. The low pressure sodium vapor pressure not more than a few. The low pressure sodium lamp discharge radiation is concentrated in 589.0 nm and 589.6 nm two double D lines. They are very close human visual curves of the highest value (555 nm), so that the luminous efficiency is extremely high, at present has reached 200 lumens per watt (LM / W), become all kinds of electric light source in the luminous efficiency highest energy-saving light source. High pressure sodium vapour pressure greater than 0.01 MPa work. High pressure sodium lamp is for low pressure sodium lamp color is too strong, the color is very poor, and the development of long tube discharge faults. The high pressure sodium lamp is divided into ordinary type (standard type), the luminous efficiency of 130lm / W, color rendering index RA = 25; improved, the luminous efficiency of 75lm / W) was, color rendering index RA = 60; high color color, its luminous efficiency is 45 ~ 60lm / W, color rendering index RA = 80 ~ 85 high-voltage sodium lamp used a golden white light, it has a luminous efficiency, less power consumption, long service life, through fog and luring etc. advantages. Widely used in road, highway, airport, dock, dock, station, square, street intersection, industrial and mining enterprises, parks, garden lighting and plant cultivation.

High color high-pressure sodium lamp is mainly used in gymnasium, exhibition hall, amusement parks, department stores and hotels and other places lighting. High pressure sodium lamp discharge material vapor pressure is very high, namely high atomic density of sodium, sodium atoms and electron collision between the number of frequent, the resonance radiation broadening of spectral lines and other visible spectrum of radiation, so the high-pressure sodium lamp light color is better than that of low pressure sodium lamp. High pressure sodium lamp is a kind of high intensity gas discharge lamp. Due to the negative resistance characteristics of the gas discharge lamp, if the bulb is connected to the grid, its working condition is unstable, and the discharge process continues. Sodium lamp and low-pressure sodium lamp and high pressure sodium lamp. The low pressure sodium vapor pressure not more than a few.

Due to the negative resistance characteristics of the gas discharge lamp, if the bulb is connected to the grid, its working condition is unstable, and with the discharge process continues, it will lead to the infinite current in the circuit.
