[0028] By adopting the above technical solution, the service life of the power controller 4 of the street lamp is generally 2-3 years, which is lower than that of other components such as the LED light row 3. Therefore, the power controller 4 needs to be replaced in time after reaching the service life. When replacing the power controller 4, the bolts connecting the light board 1 and the shell 5 are removed to separate the light board 1 from the shell 5. Then, the power controller 4 in the shell 5 is taken out and replaced. After replacing the new power controller 4, the light board 1 and the shell 5 are fixedly connected. It is very convenient to remove and install the power controller 4.

[0033] The working principle of the present invention is as follows: the connector 6 is sleeved with the end of the connecting rod 11, and the insertion of positioning pins into the multiple positioning holes 10 on the connector 6 can increase the stability of the connection between the connector 6 and the connecting rod 11; the power controller 4 generates heat during operation, and this heat can be dissipated to the outside through the multiple heat dissipation slots 9 at both ends of the housing 5, thereby preventing heat from accumulating in the housing 5 and preventing high temperature from having a negative impact on the power controller 4, thereby ensuring the normal operation of the power controller 4 and extending the service life of the power controller 4;

[0034] The service life of the power controller 4 of the street lamp is generally 2-3 years, which is lower than that of other components such as the LED light row 3. Therefore, the power controller 4 needs to be replaced in time after reaching the service life. When replacing the power controller 4, the bolts connecting the light board 1 and the shell 5 are removed to separate the light board 1 from the shell 5. Then, the power controller 4 in the shell 5 is taken out and replaced. After replacing the new power controller 4, the light board 1 and the shell 5 are fixedly connected. It is very convenient to remove and install the power controller 4.

[0035] When connecting the connector 6 to the housing 5, the connection direction of the connector 6 and the housing 5 can be changed by rotating the connector 6, so that the connector 6 and the housing 5 can be connected at a 180° angle or a 90° angle; by changing the connection position relationship between the connector 6 and the housing 5, the angle between the light board 1 and the multiple LED light rows 3 and the ground can be changed, so that the rear lamp head can adapt to the usage needs of different regions and different road sections, thereby increasing the applicability of the lamp head.
