After the light bulb starts, an 1C31132G01  is generated between the electrodes at both ends of the arc tube. Due to the high temperature effect of the arc, the sodium mercury inside the tube is heated and evaporated into mercury vapor and sodium vapor. The electricity emitted by the cathode collides with atoms in the discharge material during its movement towards the anode, causing it to obtain energy and generate ionization excitation. Then, it returns from the excited state to a stable state; Or it can change from an ionized state to an excited state, and then return to the infinite cycle of the pentane. The excess energy is released in the form of light radiation, producing light.
The vapor pressure of the discharge material in a high-pressure sodium lamp is very high, which means that the density of sodium atoms is high, and the number of collisions between electrons and sodium atoms is frequent, which widens the resonance radiation spectrum and produces radiation from other visible spectra. Therefore, the light color of a high-pressure sodium lamp is better than that of a low-pressure sodium lamp. High pressure sodium lamp is a high-intensity gas discharge light bulb. Due to the negative resistance characteristics of gas discharge bulbs, if the bulbs are connected separately to the power grid, their working state is unstable. As the discharge process continues, it will inevitably lead to an infinite increase in current in the circuit, and finally, the 1C31132G01  or components in the circuit will be burnt out by overcurrent.

High pressure sodium lamps, like other gas discharge bulbs, operate in an arc discharge state, with a negative slope in the volt ampere characteristic curve, meaning that the bulb current increases while the bulb voltage decreases. Under constant power supply conditions, in order to ensure the stable operation of the light bulb, a circuit component with positive resistance characteristics must be connected in series in the circuit to balance this negative resistance characteristic and stabilize the operating current. This component is called a ballast or current limiter. 1C31132G01 , capacitors, inductors, etc. are all capable of limited current action. Resistive ballasts are small in size and cheap in price. When used in conjunction with high-pressure sodium lamps, they may encounter difficulties in starting. During operation, the resistance generates a high amount of heat, requiring large heat dissipation space and high power consumption, which will lead to a decrease in the overall lighting efficiency of the circuit.
