LED street lamp for urban lighting

Abstract

The invention relates to the technical field of LED street lamps, and discloses an LED street lamp for urban lighting, which comprises a lamp post, a fixing frame fixedly sleeves the top of the outersurface of the lamp post, a water inlet hopper is fixedly connected to the left side of the lower surface of the fixing frame, a communicating pipe is fixedly connected to the interior of the water inlet hopper, and an annular transparent heat dissipation shell fixedly sleeves the bottom of the water inlet hopper; the bottom of the annular transparent heat dissipation shell is sleeved with a transparent temporary storage hopper in a threaded mode. According to the LED street lamp for urban lighting, through cooperation of the water collecting funnel, the annular groove and the gravity water dispersing device, rainwater collected by the water collecting funnel can be conveniently used for cooling and dissipating heat of the lamp tube, it is guaranteed that heat dissipating water in the annular groove is flowing rainwater, the lamp tube is effectively cooled, the situation that dead water is formed when rainwater is stored in the annular groove, the annular transparent heat dissipation shell is corroded due to bacteria breeding can be avoided, so that the effect of protecting the annular transparent heat dissipation shell is achieved, and the service life of the annular transparent heat dissipation shell is prolonged while the lamp tube is effectively cooled.

Description

technical field [0001] The invention relates to the technical field of LED street lamps, in particular to an LED street lamp for urban lighting. Background technique [0002] Street lamps refer to lamps that provide lighting functions for roads, and generally refer to lamps within the range of road lighting in traffic lighting. Urban street lamps not only beautify the urban environment, but also have an important impact on urban traffic and the personal safety of citizens, and can maintain urban infrastructure. And the appearance of the city, it is convenient for residents to live, beautify the city, and can also establish a good investment environment for the city. With the continuous expansion of the city, the number of street lights in the city is increasing, and the probability of street light damage, the power energy consumed by street lights, etc. Costs are also increasing. [0003] The difference between LED street lamps and conventional street lamps is that the LED ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides an LED street lamp for urban lighting, which has the advantages of effectively dissipating heat from the lamp tube, prolonging the service life of the annular transparent heat dissipation shell, improving the light efficiency utilization rate of the LED street lamp, and solving the problem of existing LED lamps. Street lamps are generally located outdoors. In order to adapt to the temperature difference between the ambient temperature and the temperature of the lamp tube, it is necessary to use a lampshade material that is resistant to high temperature and low temperature. Due to changes in the external environment and climate, in order to protect street lamps, the existing sacrificial anode cathodic protection treatment is generally used, or spraying paint, but the sacrificial anode cathodic protection method takes a long time, because of oxidation and discoloration, it needs to be replaced again Installation, but the addition of spray paint can not effectively dissipate heat, and it is easy to reduce the luminous power of LED street lights.
