Figure 1 a typical high pressure mercury lamp.
High pressure mercury vapour lamp diagram.
In case of fluorescent lamp the mercury vapour pressure is maintained at lower level a schematic diagram of mercury lamp is shown below.
Diagram working principle march 15 2020 august 13 2018 by electrical4u a low pressure sodium vapor lamp or lpsv lamp is termed as a miscellaneous discharge lamp as it possesses some characteristics of high intensity discharge hid lamps as well as it resembles fluorescent lamps in other areas.

High pressure sodium ballast wiring diagram sodium vapor lamp circuit diagram unique low pressure sodium vapour lamp perfect lamp efficacy efficiency.
The mercury vapor ballast wiring diagram is the blueprint for the ballast circuitry including the input supply voltage and grounding methods.
At the heart of the lamp is an arc tube which is fabricated from quartz with a tungsten electrode disposed at either end.
This is different from fluorescents which use the mercury vapor arc to create a weaker light that mainly creates uv light to excite the phosphors.
A sodium vapor lamp is a gas discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm.
A ground connection must be made to all ballasts to avoid shock hazard personal injury or damage to the luminaire or installation.
The tube contains a few milligrams of mercury and around 25 50 torr of pure argon as a buffer gas to carry the discharge while the lamp warms up producing.
Low pressure and high pressure low pressure sodium lamps are highly efficient electrical light sources but their yellow light restricts applications to outdoor lighting such as street lamps where they are widely used.
It uses an arc through vaporized mercury in a high pressure tube to create very bright.
In case of fluorescent lamp the mercury vapour pressure is maintained at lower level such that 60 of the total input energy gets converted into 253 7 nm single line.
The mercury vapor lamp is a high intensity discharge lamp.
Again transition of the electrons requires least amount of input energy from a colliding electron.
As pressure increases the chance of multiple collisions gets increased.
The mercury vapor lamp is a high intensity discharge lamp.
When a mercury vapor lamp is first turned on it will produce a dark blue glow because only a small amount of the mercury is ionized and the gas pressure in the arc tube is very low so much of the light is produced in the ultraviolet mercury bands.
