Sodium vapor lamps

sodium vapor lamp consists of an exhaust pipe from a heat resistant glass, containing a small quantity of metallic sodium, neon gas and two electrodes, the neon gas, the discharge start and sodium develop enough heat to evaporate. The pressure inside the pipe case, a tube of sufficient length necessary to obtain more light. To reduce the total length of the tube lamp that is usually U-shaped bent

The light produced by this> Lamp is yellow, which generates at its optimum pressure at 0.004 mm of mercury. This pressure is produced at a temperature of about 280 ° C and is necessary to maintain this temperature. To this end, even the U-tube into a container with double wall is to prevent heat loss. The double cylinder is interchangeable and can be mounted to another U-tube When replacing the inner U-tube must be very careful, because if it is broken and the ash is in contacthumidity, can cause a fire.

All discharge lamps require a higher voltage to the start time and low voltage during operation. In general, sodium vapor lamps powered by a high reactance transformer losses. At the beginning of a high voltage of 450 volts is applied across the discharge lamp, sufficient to be started. When the lamp is fully operational after 10-15 minutes, the voltage drops to about 150 volts. Due to the highReactance of the circuit is the power factor is lower, and then a pf improvement capacitor is connected.

The efficiency of a sodium vapor lamp low pressure is very high (about 40-50 lumens per watt) and produces a specific wavelength of light with a yellow color. Sodium lamps are mainly for roads, airfield lighting and high distinction, where color is not used as required.

However, the evening was not without problems. Ferdinand Ries, musician, composer and closeKnowledge of Beethoven, described the concert: "Beethoven had a great concert December 22, 1808 in the Theater an der Wien, where for the first time in C minor and Pastoral Symphony and Fantasia for piano and orchestra and choir.
