Working Principle Of High Pressure Mercury Vapour Lamp

Lamps of today are high pressure lamps with a fused quartz inner discharge tube.

Working principle of high pressure mercury vapour lamp.

The high pressure helps increase efficiency and this was developed in 1936 35 years after the low pressure lamps came out. Friends is video me ham discuss karenge mercury vapour lamp ke bare me. Mercury vapour contained in an evacuated glass bulb vapour warmed high voltage applied to electrodes inside lamp vapour conducts and allows current flow excitation causes vapour to glow brightly. Working principle of mercury vapor lamp author.

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. After that the lamp would heat fast and mercury became a vapor. A mercury vapor lamp is a gas discharge lamp that uses an electric arc through vaporized mercury to produce light the arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb. Electrical articles 8 may 18 the extensive use of the mercury vapor lamp depends entirely upon the versatility of the mercury vapor as regards pressure temperature voltage and other characteristics each change resulting in a lamp of different spectral quality and.

The light would intensify as the arc grew stronger in the tube. 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. Is video me ham mercury vapour lamp ke working principle construction or uske connection ke bare me discuss krenge ki.
