Combined type modularized LED streetlamp

Abstract

The invention relates to a combined type modularized LED streetlamp. The combined type modularized LED streetlamp comprises a sealed electric appliance box (1), and a power drive module (2) is arranged in the sealed electric appliance box (1). A connecting device (3) used for being connected with a lamp pole is arranged at the tail end of the sealed electric appliance box (1). A frame (4) is arranged at the front end of the sealed electric appliance box (1). A modularized LED lamp (5) used for illumination is arranged in the frame (4) and electrically connected with the power supply drive module (2). A heat dissipation piece (6) is arranged on the back side of the modularized LED lamp (5) and provided with a plurality of through holes (7) communicated with the upper and lower end surfaces of the LED streetlamp. Rainwater can be utilized to automatically clean the LED streetlamp to keep the LED streetlamp clean and prolong the service life of the LED streetlamp; air convection can be utilized to facilitate heat dissipation of the LED streetlamp.

Description

【Technical field】 [0001] The invention relates to a combined modular LED street lamp. 【Background technique】 [0002] As a solid-state lighting source, LED has become the development trend of a new generation of light sources due to its long life, high luminous efficiency, multiple light colors, one-time light distribution and directional irradiation function, and can work under safe voltage. Based on the above advantages, now Some street lamps use a large number of LED light sources as the lighting source. Due to the relatively large dust on the road, the existing LED street lamps tend to accumulate dust, which is not easy to clean the LED street lamps. On the other hand, the dust accumulates on the LED street lamps. Impregnation is easy to cause corrosion to LED street lights, affecting the appearance and service life of LED street lights. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a combined modular LED str...
