Abstract

The invention relates to the field of lighting devices, in particular to an LED street lamp comprising a lamp holder, a radiating piece and a ventilation device. The radiating piece is arranged on theupper portion of the lamp holder; the ventilation device is mounted on the upper portion of the radiating piece; an air inlet communicating with air is formed in the left end of the ventilating device, and an air outlet is formed in the right end of the ventilation device; a rotating shaft is mounted inside the ventilation device; fan blades same in size are mounted on the rotating shaft; a ceramic layer is arranged outside of the radiating piece in an embracing mode; a plurality of radiating fins are arranged on the side face of the lamp holder; a lamp plate is arranged in the lamp holder, an LED lamp panel is arranged on the lamp plate and covered with a protective board; LED lamp beads are arranged on the LED lamp panel, and radiating holes are further formed in the exterior of the LEDlamp panel; and a protective cover is arranged outside the lamp holder, a fogging surface coating is arranged on the protective cover, and a light guide plate is arranged on the inner side of the protective cover. The LED street lamp has the advantages of reasonable structure and good radiating effect.

Description

technical field [0001] The invention belongs to the field of lighting devices, and in particular relates to an LED street lamp. technical background [0002] With the rapid development of social economy and the enhancement of people's awareness of energy conservation and environmental protection, the old-fashioned incandescent lamps have already left people's sight, and energy-saving LED lamps have emerged. In recent years, with the rapid development of LED technology, its luminous efficiency has doubled, and its cost has also dropped significantly. It has many advantages such as energy saving, environmental protection, and long life, and is widely used in various lighting fields. [0003] However, since LED lamps are extremely sensitive to temperature, a rise in temperature will affect the lifespan, effect, and reliability of LEDs. Therefore, how to ensure the heat dissipation of LED street lamps has become an important issue that users pay attention to. Contents of the i...
