PURPOSE: A streetlight is provided to prevent the contamination of a lamp cover and improve the illumination of a lamp by exterminating vermin. CONSTITUTION: A streetlight includes a controller which controls electrically connected components according to a preset program. A balance arm(14) is integrated with the upper side of the streetlight and is extended to a rod. A lamp device(16) is integrated with the end of the balance arm and is made of aluminum. A lamp(18) is electrically connected to the controller and is turned on according to the control signal from the controller. A plastic cover(20) protects the lamp. An air spray nozzle(38) instantaneously sprays strong air through a spray hole. A wire net(40) is installed to prevent foreign materials from being inputted to the inside of an inhalation pipe. A vermin sensor(28) senses vermin collected in the streetlight and transmits the vermin value to the controller. |
