Road lamp heat radiation outer housing

Abstract

A road lamp heat radiation outer casing comprises a lamp body supporting base for mounting the road lamp on the lamp post and a lamp body base for connecting the lamp body supporting base. The lower surface of the lamp body base is provided with at least one downwardly-extending radiating fin, and the distance from the resultant mass centre of all the radiating fins to a first end surface of the lamp body base is smaller than the distance from the resultant mass centre of all the radiating fins to a second end surface of the lamp body base. Adopting such design, the whole lamp body volume is less, the weight is lightened, the installation is convenient, the mass center of the lamp body moves backward, the applied force at the connection point of the lamp body supporting base and the lamp body base is reduced, and the applied force point is transferred, thereby leading the product to be more fixed.

Description

technical field [0001] The invention relates to the field of street lamps, in particular to a heat dissipation housing for street lamps. Background technique [0002] Modern urban road construction requires the lighting rate of street lights to be above 98%. If the street lights cannot work normally, it will not only affect the image of the city, but also cause traffic safety accidents. At present, the lamp tubes of street lamps used on roads generally adopt high-pressure sodium lamps or halogen lamps, which have the disadvantages of large energy consumption and short service life. [0003] In order to alleviate the pressure of urban electric energy use, high-power LED lamps with low energy consumption and long service life are gradually used to replace the traditional high-pressure sodium lamps or halogen lamps. However, whether it is the traditional high-pressure sodium lamp or halogen lamp, or the high-power LED lamp, a large amount of heat will be generated during use. ...

AI Technical Summary

Problems solved by technology

However, whether it is the traditional high-pressure sodium lamp or halogen lamp, or the high-power LED lamp, a large amount of heat will be generated during use. If the heat cannot be dissipated in time, the service life and lighting effect of the street lamp will be seriously affected.

[0004] Therefore, in order to increase the service life of the street lamp and enhance the lighting effect, people have developed a heat dissipation shell, but the heat dissipation efficiency of the existing heat dissipation shell is not high, and the size of the heat dissipation shell needs to increase relatively with the size of the high pressure sodium lamp or halogen lamp. Large, the volume will increase accordingly, causing installation inconvenience, and increasing the force at the connection point between the lamp body and the lamp body of the street lamp, thereby reducing the firmness of the product
