Problems solved by technology

[0003] The LED street lamps of the prior art follow the traditional high-power LED lamp tubes for high-pressure mercury lamps, which are composed of a lamp housing and a lampshade. The heat decay of the lamp tube is accelerated, which greatly shortens its service life, resulting in high maintenance costs for replacing LED lamp tubes in municipal street lamp management; therefore, the existing technology has poor heat dissipation of lamps, short service life of LED lamp tubes, and high maintenance costs of LED street lamps. problems and deficiencies

Abstract

The invention discloses a one-piece enhanced heat emission LED (light-emitting diode) street lamp. The street lamp comprises a lamp housing (1), an LED tube (2), a diffusing lens (3) and an electronic driver (4). With adoption of the components, the lamp housing adopts a monomer structure blackened aluminum alloy component and is provided with a lamp trough, an electrical chamber, a chamber cover, a connector, and a large area upper radiating rib and a lower radiating rib; the LED tube is fixed in the lamp trough and is sealed through the diffusing lens; the electronic driver is fixed in the electrical chamber and is sealed through the chamber cover; the LED tube and the electronic driver are mutually connected through a wire. The operating heat of the LED tube is rapidly emitted through the upper radiating rib and the lower radiating rib during operation, and purposes of enhancing heat emission, prolonging the service life of the LED tube and reducing the maintenance cost are achieved through a technical scheme of prolonging the service life of the LED tube by reducing the operating temperature and slowing down thermal decay.

Description

technical field [0001] The invention relates to a street lamp, in particular to a single-piece LED street lamp with enhanced heat dissipation for road lighting using a high-power LED lamp tube as an electric light source. Background technique [0002] The LED lamp is an electroluminescent device of a semiconductor light-emitting diode. The brightness of the high-power LED lamp will be irreversibly attenuated by the heat generated during its own work, which is called thermal attenuation; [0003] The LED street lamps of the prior art follow the traditional high-power LED lamp tubes for high-pressure mercury lamps, which are composed of a lamp housing and a lampshade. The heat decay of the lamp tube is accelerated, which greatly shortens its service life, resulting in high maintenance costs for replacing LED lamp tubes in municipal street lamp management; therefore, the existing technology has poor heat dissipation of lamps, short service life of LED lamp tubes, and high maint...
