Embodiment Construction

[0020] It can be seen from Fig. 1 that an LED street lamp provided in this specific embodiment includes: a light pole 1 and a lamp body; the lamp body includes: a lampshade 2, a radiator assembly 3, a sealing ring 4, a connecting column 5, a driver 6, Light source assembly 7 and reflector 8.

[0021] The end of the light pole 1 (because the light pole is very long, only the part where the upper end of the light pole is bent downward) is bent downward, and the light pole 1 is hollow and has an exhaust channel 10; The end is also provided with a lamp body mounting plate 11 .

[0022] The lampshade 2 is arranged at the extreme end of the lamp pole 1 and is fixedly installed on the mounting plate. In order to prevent rainwater from entering the interior of the lampshade 2 from the gap between the lamppost 1 and the lampshade 2 , the sealing ring 4 is arranged between the lamp body mounting plate 11 of the lamppost 1 and the lampshade 2 . The radiator assembly 3 , the driver 6 , ...

Abstract

The invention discloses an LED street lamp which comprises a lamp pole, a lamp shade, a connection column, a light source component, a reflective cover, a radiator component and a driver; the tail end of the lamp pole bends down, the lamp shade is arranged at the most tail end of the lamp pole, a radiator is fixedly connected with the most tail end of the lamp pole through the connection column, the light source component and the radiator component are fixedly connected and the two are electrically connected with the driver, the reflective cover is covered around the light source component, and the light source component, the reflective cover and the radiator component are arranged in the lamp shade; the driver is arranged on the radiator, and between the radiator and the tail end of the lamp pole; and an exhaust channel is arranged in the lamp pole. In the LED street lamp of the technical scheme, because the driver is arranged in the lamp body and the position is very close to the light source component, the line resistance is small, and electric power is saved; and in addition, the invention further optimizes the structure in the lamp body so that the structure of the lamp body is compacter, can produce forced convection effect when the street lamp works and better takes away the heat on the radiator and the driver, so that the cooling effect is better.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED street lamp. Background technique [0002] LED (Light Emitting Diode) has the characteristics of high luminous efficiency and long life, so it has been loved by people since its appearance. However, LED has been mostly used in the field of indication for a considerable period of time, and its application in the field of lighting is seldom. In recent years, with the emergence of blue high-brightness LED technology, LEDs can mix white light suitable for lighting. Therefore, high-brightness white LEDs are more and more widely used in the field of lighting, especially in the field of street lighting. In recent years, the number of patents related to LED street lamps has grown rapidly, and related technologies have become more and more mature, but there are still some areas that need to be further improved. For example, the drivers of existing LED street lamps are mostly inst...
