Embodiment

[0035] First, the light engine is electrically connected to the power supply structure and the lightning protector; then the mica sheet is set on the surface of the lamp body, and the light engine is set in the plastic isolation board and placed on the surface of the mica sheet, so that the mica sheet can be used to The heat of the light engine is transferred to the radiating fins to realize heat dissipation. Finally, the first / second waterproof ring, glass lens, aluminum decorative plate, pressure ring and other structures are placed and fastened with screws to complete the installation.

Abstract

The invention discloses an LED (light-emitting diode) street lamp which comprises a lamp body, a power supply mechanism, a light engine, a mica spacer, a separator and a glass lens, wherein the light engine is arranged on the surface of the lamp body, the mica spacer is arranged between the light engine and the surface of the lamp body, the separator is arranged at the top of the light engine, the glass lens covers the surface of the lamp body corresponding to the light engine, and the power supply mechanism is electrically connected with the light engine. The LED street lamp has the advantages that a lightning arrester is additionally connected between the light engine and an external wire, lightning resistance is higher than 10KV, a mica plate is added between the light engine and a radiator to function in radiating and insulating, a plastic cover is arranged between the light engine and a screw, a fixing hole of the light engine is fixed by the plastic cover in an insulating manner, the problem of failure due to surge of an existing light engine is solved, and the problems of insufficient voltage resistance and electro-migration of the light engine are solved.

Description

Technical field [0001] The invention relates to the technical field of LED lighting, in particular to a new type of LED street lamp. Background technique [0002] LED street lights, as the name suggests, are lamps used in road lighting. At present, LED street lights are mostly manufactured in the form of separate light sources and power sources. The light source is mainly modular or integrated, and the power source is mainly driven by low-voltage output. In order to meet the reliability of street lamps, the manufacturing cost is high, and the reliability of many components is not high. [0003] The light engine (LED light Engine) refers to an overall combination of LED packages (components), LED drivers, and other brightness, thermal, mechanical, and electrical components. Its high system efficiency and low cost have become the focus of future research and promotion of major lighting manufacturers. But its reliability (surge resistance, insulation, electromigration) needs to be ...
