Problems solved by technology

However, because the opening of the heat dissipation channel near the end of the first lamp body is blocked by the first lamp body, the air flow is not good, and the heat taken away is less, and after long-term use, dust and other sundries are easy to accumulate in the heat dissipation channel, which is difficult to remove , when it rains, the accumulated rainwater is also difficult to discharge, which will seriously affect the heat dissipation effect of street lamps

Abstract

The invention relates to a LED street lamp body, comprising a first lamp body and a second lamp body which are connected. The first lamp body has a first containing chamber for containing part of parts of the LED street lamp body for controlling the circuit. The second lamp body bottom face has a second containing chamber for containing the LED light source of the LED street lamp body. The bottom face of the first lamp body and the bottom face of the second lamp body constitute the bottom face of the LED street lamp body. The top face of the second lamp body has a plurality of heat radiating fins. Two adjacent heat radiating fins constitute a heat radiating channel. At least a part of the heat radiating channel is far away from one end of the first lamp body and extends to the first lamp body. A ventilation channel for communicating the heat radiating channel is arranged in the first lamp body. One end of the ventilation channel is opened on the bottom face of the first lamp body. The LED street lamp body has a good heat radiation effect and long service life.

Description

Technical field: [0001] The invention relates to road lighting equipment, more specifically, to a lamp body of an LED street lamp. Background technique: [0002] Due to the advantages of high efficiency, energy saving, safety and reliability, and long service life, LED light-emitting diodes have been widely used in various fields, especially lighting equipment, and have gradually replaced traditional light-emitting components. [0003] Especially with the emergence of high-power LEDs, the application fields of LEDs have spanned from indicator lights and instrument panels to high-efficiency road lighting. However, due to the dense application of high-power LEDs and the general need for sealing of lamps, it is difficult to dissipate heat and seriously reduce the service life of LEDs. In order not to make the heat affect the life of the light-emitting diodes, adopting an appropriate heat dissipation structure has become a problem that must be solved for street lamps. [0004]...
