Sodium Vapor Lamp Circuit
The sodium vapor lamp circuit diagram is shown in below. Here, the type of lamp uses in this circuit is a low-power sodium vapor lamp (LPSVL). The construction of this light is like a mercury vapor lamp. In this lamp configuration, two electrodes, E1 and E2, along with a capacitor (C), a choke (L), and a small step-down transformer (T) are connected in series with the lamp. The choke (L) is an inductor is Connected in series with a low-power sodium vapor lamp. It stabilizes the discharge in the same way that overload protection does. The transformer utilized in the above circuit is a step down transformer for reducing the voltage supply and settling the circular segment. The vapor lamp, choke, and transformer are all connected in series to heat the cathode electrode “E1” inside a G1 glass tube that contains sodium and a small amount of argon or neon gases. This G1 glass tube is set in a G2 evacuated external tube.
Sodium vapor is extremely active chemically, so the glass lamp is planned firmly to Withstand the hot sodium vapor action. By keeping the discharge tube’s exact temperature at 300 degrees Celsius, so we can achieve maximum efficiency and operating conditions and reduce the heat loss from the tube.
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.
