Components of Sodium Vapor Lamp
The components of sodium vapor lamp are discussed below in detail:
- Outer Bulb : The outer bulb is the first part, usually made of borosilicate glass. The inner components of the sodium vapor lamp are shielded from the elements and provided with thermal insulation by this bulb. The bulb’s external structure also helps to maintain the necessary operating temperature for optimal performance and efficiency.
- Ballast: To manage the current that is passing through the sodium vapor lamp, a ballast is very importantly employed. The ballast controls the flow of electrical energy ensuring and guarantees that the lamp works safely and efficiently. It keeps excessive current from current to and contacting the light, prolonging its lifespan and maintaining stable illumination.
- Sodium and Mercury: A sodium vapor lamp’s primary illuminating agents are sodium and mercury. The arc tube contains exceptionally little measures of these components in their vapor forms. At the point when the lamp is ignited, an electric discharge through the arc tube, making the sodium and mercury fumes become ionized and emit light.
- Electrodes: To light and support the electric release inside the curve tube, two anodes are significantly fundamental. These electrodes, which are made of a refractory metal like tungsten, are coated in a material that makes it easy to start them up and keeps them running smoothly. The terminals give the fundamentally electrical associations with the light to work in an extremely legitimate manner.
- Neon Gas (Ne): A limited quantity of neon gas is used to initiate the discharge in the light.
- Arc Tube: Contained inside the outer bulb is the core of the sodium vapor light – the arc tube. A small, cylindrical design made of an extremely top notch transparent material, such as, aluminum oxide is the arc tube. A mixture of noble gases, typically argon, and a small amount of neon can be found inside the arc tube, which serves as a very useful starting aid.
- Sodium (Na) Metal: The light contains a modest quantity of metallic sodium, which is a key component for producing the yellow-orange light when it is vaporized and excited by an electric discharge.
Sodium Vapor Lamps
A light where an electric discharge happens all through a metallic vapor is known as a vapor lamp. These lights are accessible in two types sodium vapor lamps and mercury vapor lamps which emit various shades of light like thick blue and yellow respectively. These lights are highly efficient and provide concentrated illumination, making them ideal for open spaces and for lighting up large distances.
A vapor lamp typically includes a double tube where vapor is enclosed within the tube while the outside tube is empty with air, so it retains risky hazardous UV radiation.
