Outdoor LED lighting device

Abstract

The invention relates to an outdoor LED lighting device. The device comprises a rear shell, an LED lamp panel, a lampshade and a lamp post, the lamp panel is fixed in the rear shell, the lampshade is connected with the rear shell, the rear shell is fixed to the lamp post, a heat dissipation column is arranged in the center of the LED lamp panel, a plurality of first heat dissipation holes are evenly formed in the heat dissipation column, the heat dissipation column penetrates through the LED lamp panel, and the rear end is flush with the back face of the LED lamp panel; a plurality of reflecting covers are arranged on the LED lamp panel, the reflecting covers are arranged in the circumferential direction with the heat dissipation column as the center, LED light sources are arranged in the reflecting covers, and light transmitting parts are arranged at the positions, corresponding to the reflecting covers, of the lampshade; first cooling fins are arranged on the two sides of the lampshade and make contact with the cooling columns; a second cooling fin is arranged on the back face of the LED lamp panel, the second cooling fin is attached to the LED lamp panel, a third cooling fin perpendicular to the second cooling fin is arranged on the second cooling fin, the third cooling fin extends towards the direction of the rear shell, and a distance is formed between the third cooling fin and the rear end of the rear shell; and a heat dissipation opening is formed in the position, close to the rear shell, of the lamp post. The device is good in heat dissipation effect, and meanwhile, the leakproofness is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an outdoor LED lighting device. Background technique [0002] With the development of LED technology, LED has become more and more widely used in the field of lighting. Its superior energy-saving performance makes it the development direction of lighting. The existing outdoor LED lighting devices generally use LED lamp beads or LED lamp panels as light sources. Set in a closed shell, the shell is fixed on the lamp post, and the light-transmitting glass is set on the shell so that the light emitted by the light source can diffuse out. With the application of outdoor LED lighting devices, it is found that when the light source emits light in this structure, there will be The heat is difficult to dissipate, and the light source is easily damaged under continuous use. Contents of the invention [0003] The object of the present invention is to provide an outdoor LED lighting devi...
