Abstract

The invention relates to a waterproof cover of an LED (Light Emitting Diode) street lamp. The waterproof cover of the LED street lamp comprises an upper casing and a lower casing; the upper casing is an integrally formed arc-shaped top cover; the lower casing comprises connection sections which are arranged at the two ends and a middle arc-shaped section; and the connection sections are connected with an inner edge portion of the upper casing in a sealing mode through an annular-shaped concave portion. Ventilation holes are arranged in the annular-shaped concave portion and protective screen sheets are arranged inside the ventilation holes to serve as optimization. The waterproof cover of the LED street lamp has the advantages of avoiding rainwater leakage of the upper casing due to the fact the upper casing is the integrally formed arc-shaped top cover and avoiding entering of side rainwater due to the fact that the connection sections of the lower casing are connected to the inner edge portion of the upper casing through the annular-shaped concave portion.

Description

technical field [0001] The invention relates to a protective cover for street lamps, in particular to a waterproof cover for LED street lamps. Background technique [0002] LED (Light Emitting Diode) has many advantages such as long life, low energy consumption, small size, strong shock resistance, short response time, less heat generation and variable light color. In order to achieve the purpose of energy saving and emission reduction, LED street lamps are being vigorously promoted in various places. [0003] At present, the shell of the existing LED street lamp is divided into upper and lower parts, the upper and lower parts are casted from aluminum, the middle part has a hollow part, and a reflector is installed in the hollow part. Due to the inconsistency of the expansion coefficient of the materials of each component, the change of temperature will cause gaps at the connection of each component, and the leakage of rainwater is prone to cause short circuit and damage of...
