LED street lamp easy to clean

Abstract

The invention provides an LED street lamp easy to clean. The LED street lamp comprises a lamp post, a lamp arm arranged on one side of the lamp post, a lamp holder arranged on the lower side of the lamp arm, and an LED bulb installed on the lamp holder; the exterior of the lamp post is fixedly provided with a water storage barrel in a sleeving manner; an closed annular water storage tank with an upward opening is formed between the water storage barrel and the lamp post, and the bottom wall of the annular water storage tank is closed; the exterior of the lamp post is further fixedly provided with an annular filter plate in a sleeving manner, and the annular filter plate is used for covering the opening of the annular water storage tank; the annular water storage tank is internally providedwith a water pump; the exterior of the LED bulb is provided with circular rings in a sleeving manner, and the circular rings are internally provided with ring cavities; nozzles are arranged between the circular rings and the LED bulb, and water inlets of the nozzles communicate with the ring cavities; water outlets of the nozzles directly face the LED bulb, and the lamp arm is fixedly provided with an electric push rod which can be used for driving the circular rings to do translation motion up and down; the side wall of the water storage barrel is provided with a drainage outlet, and the circular rings are provided with water inlets; and an outlet of the water pump communicates with the drainage outlet through a connecting pipe, and the drainage outlet communicates with the water inletsthrough stainless steel corrugated hoses. The LED street lamp has the advantage that the LED bulb is easy to clean.

Description

technical field [0001] The invention relates to a street lamp, in particular to an LED street lamp which is convenient for cleaning. Background technique [0002] With the development of technology, LED has been widely used. LED lighting is light-emitting diode lighting, which is a semiconductor solid light-emitting device. Energy causes photon emission, and directly emits red, yellow, blue, and green light. On this basis, using the principle of three primary colors, adding phosphors can emit red, yellow, blue, green, blue, orange, purple, white, etc. Light of any color. LED lamps are lighting fixtures that use LEDs as light sources. [0003] With the popularity of LED lights, not only many LED lights are used in homes, but also a large number of LED lights are used as street lights. Existing LED street lamps generally include a base, a lamp post vertically fixed on the base, a lamp arm arranged on one side of the lamp post, a lamp holder fixed on the lower side of the la...

Problems solved by technology

[0004] In actual use, because the LED bulb is directly exposed to the external environment, a thick layer of dust will adhere to the outer surface of the LED bulb under long-term use, which will affect the light transmittance of the LED bulb and make the area illuminated by the street lamp more difficult. getting smaller
