LED road lamp

Abstract

The invention relates to a LED street lamp, in particular to a tubular LED street lamp. The LED street lamp comprises a lamp body and is characterized in that the lamp body comprises a head body, a middle body and a tail body; the head body and the tail body are respectively connected with both ends of the middle body; the head body is provided with a hole position used for connecting with the lamp stem of the LED street lamp; the front surface of the middle body is provided with an open lamp tube cavity; the inverse surface of the middle body is provided with a head dissipation hole used forcommunicating the lamp tube cavity with the external space; the LED street lamp also comprises a group of lamp tubes which are arranged in the lamp tube cavity. The invention provides a LED street lamp which has replaceable lamp tubes. The invention also provides a LED street lamp which has good heat dissipation performance.

Description

technical field [0001] The invention relates to an LED street lamp, in particular to a tube-type LED street lamp. Background technique [0002] Compared with traditional street lights, LED street lights not only have the characteristics of good chromaticity, maintenance-free, and long life, but more importantly, they are more energy-efficient than traditional street lights. For the industrialization of LED street lamps, heat dissipation is the biggest problem. There are also LED street lamps that use ordinary lamp bodies and fans to dissipate heat, but it is difficult to popularize. The energy consumption of the fan itself is one aspect. More importantly, the life of the fan is very short, and the advantages of LED lamps cannot be fully utilized. [0003] For the traditional integral LED street lamp, its maintenance work is complicated, and even the work of the LED street lamp is affected because the maintenance time is too long. And outdoor maintenance is not only costly,...

AI Technical Summary

Problems solved by technology

There are also LED street lamps that use ordinary lamp bodies and fans to dissipate heat, but it is difficult to popularize. The energy consumption of the fan itself is one aspect. What is more important is that the life of the fan is very short, and the advantages of LED lights cannot be fully utilized.

[0003] For traditional integral LED street lights, the maintenance work is complicated, and even the work of LED street lights is affected because of the long maintenance time.

Moreover, outdoor maintenance is not only costly, but also limited by weather and other factors, making it inconvenient to operate

In fact, most of the failures of LED street lamps are caused by the scrapping of LED chips due to poor heat dissipation or other reasons.
