Street lights commonly use sodium vapor discharge lamps that produce light through ionizing gas with electrodes when high voltage is applied, without a filament. Discharge lamps have a glass tube containing gas at low pressure with electrodes at each end, and work by ionizing the gas which causes electrons and ions to collide and produce light of different colors depending on the gas used, such as yellow light from sodium.

Discharge lamps In most of the streets sodium vapor lamps are used as street lights. These lights has no filament . They are called discharge lamps.
PARTS AND WORKING OF DISCHARGE LAMP PARTS A glass tube having a suitable gas at low Pressure Electrodes are connected at the ends of the glass tube
WORKING WHEN A HIGH VOLTAGE IS APPLIED TO THE ELECTRODES THE GAS GET IONIZED . THESE IONS AND ELECTRONS ARE COLLIDE WITH EACH OTHER & LIGHT IS PRODUCED. THESE IONS AND ELECTRONS ARE COLLIDE WITH OTHER MOLECULES LIGHT IS PRODUCED.
