Easily-maintained LED street lamp

Abstract

The invention discloses an easily-maintained LED street lamp. The street lamp comprises a shell front panel, a shell back board and multiple groups of LED lamp units, wherein the LED lamp units consist of a single LED lamp, a double-side convex lens component and a semi-cylindrical arc-shaped lens arranged on the shell back board in turn; the double-side convex lens component is connected with the single LED lamp through a buckle structure of a base; and the semi-cylindrical arc-shaped lens is arranged on the shell front panel. An assembling structure is optimized when the structure in a patent document numbered CN201259147Y is realized. When a single LED lamp is damaged, the damaged single LED lamp can be replaced by opening the shell front panel, unscrewing the buckle between the double-side convex lens component and a corresponding single LED lamp and taking the double-side convex lens component down. After replacement is finished, recovery is performed in a reverse sequence so as to finish the maintenance of the LED street lamp. The street lamp has the advantages of simple and convenient operation, high maintainability and corresponding reduction in use cost of a customer.

Description

technical field [0001] The invention relates to an LED street lamp, in particular to an LED street lamp which is easy for daily maintenance. Background technique [0002] I disclosed an LED street lamp lens device in the Chinese patent document CN201259147Y earlier, which can meet the needs of LED high-power light sources of more than 1W applied to street lamps, and can make the optical path longer and the light distribution more uniform. The device includes an LED lamp, a convex lens, a housing and a bracket fixed inside the housing. Its special feature is that an arc-shaped lens is arranged outside the convex lens, which is semi-cylindrical and can diverge the incident circular light spot in the longitudinal direction. Make the outgoing light grow into an ellipse or rhombus. The use of curved lenses can achieve a smooth transition while increasing the irradiation area, effectively controlling the light attenuation, improving the effective luminous rate of the LED light so...

AI Technical Summary

Problems solved by technology

[0003] However, the power of a single LED lamp is relatively low. This inherent characteristic requires that its application to street lamps must be composed of multiple LED lamps. That is to say, it is inevitable to assemble multiple such LED street lamp lens devices and LED lamps in one street lamp. The combination of lamps has a relatively complicated assembly structure, and a negative effect is that if some LED lamps of the street lamp are damaged, it is impossible to easily remove the corresponding lens device on site to complete the replacement of the damaged LED lamp, resulting in poor maintainability. , which on the other hand leads to an increase in the user's cost of use
