Energy-saving LED street lamp

Abstract

The invention discloses an energy-saving LED street lamp structurally comprising a wire embedding supporting seat, a supporting rod, a mounting ring and a lighting mechanism; the top of the embedded wire supporting seat is welded with the bottom of the supporting rod; the angle of a light outlet hole is adjusted through the overall rotation of a steering plate; light is subjected to wavy reflection through a reflection plate on the inner wall of an irradiation groove; in the rotating process of the steering plate, a push plate drives an irradiation plate to generate angle deviation; therefore,the irradiated light is reflected to two sides; the range of light irradiation is enhanced, illumination is more uniform, heat is conducted into a gas inlet through cooling fins. Heat is prevented from flowing back through the gas inlet; an expansion block is expanded through heat, at the moment, a plug and a rubber ring move at the same time, the rubber ring is pushed out of the lower end of a heat discharging opening, the heat discharging opening discharges the heat, after heat dissipation is completed, the plug and the rubber ring reset to block the heat discharging opening, and rainwaterand dust are prevented from entering a cover shell from the heat discharging opening.

Description

technical field [0001] The invention relates to the field of LEDs, and more specifically, relates to an energy-saving LED street lamp. Background technique [0002] Street lamps are an important part of urban lighting. Traditional street lamps use high-pressure sodium lamps. The overall low luminous efficiency of high-pressure sodium lamps causes a huge waste of energy. High-power LED street lamps are green, environmentally friendly, and pollution-free, and are more widely used in street lamp products. , but because the irradiation of high-power LED street lights is relatively concentrated, the range of light intensity dispersion of LED street lights is narrow, and the irradiation light intensity is linear, resulting in low uniformity of irradiation, and in order to prevent rain and dust from entering To the interior of high-power LED street lamps, LED street lamps must be kept sealed, resulting in high-power LED street lamps accumulating more heat inside when working in rai...

Reduced, resulting in continuous shortening of the irradiation distance of LED street lights in the distance
