High voltage sodium lamp working principle circuit diagram
The high voltage sodium lamp generates high voltage (starting voltage about 1000V) through the energy storage of the ballast and trigger, and triggers the lamp to be lighted.
And by ionized into the excited state, then turn back to the base e, and has an infinite loop, then the electric energy will be in excess of light radiation release, which generates a source of high pressure sodium lamp, this is the working principle of high pressure sodium lamp.
While the emission cathode end tube power, in the movement process of steering the anode, the electric atoms emitted by the impact, the atom can obtain electric energy, and to stimulate ionization degree from excited states began to turn back to the stable state
When the high-pressure sodium lamp bulb open at both ends of the arc tube electrode will produce an arc, so the arc is made of sodium mercury arc tube all by the heat of evaporation, a sodium vapor, or mercury vapor
