本发明的路灯，在LED灯头开启时，正常情况下，当温度传感器的测量值小于设定阈值时，LED灯头温度不算高，此时为了避免开启两个散热风扇能耗高，如图1所示，第二风扇关闭，第一风扇开启，第一风扇产生的气流先经过蓄电池，一部分从第二通孔出去，另一部分继续向上经过第三圆孔经过LED灯头将热量带走(当气流经过蓄电池时被加热了，因此对LED灯头散热效果稍差)；当温度传感器的测量值不小于设定阈值时，此时LED灯头需要加强散热，因此如图2所示，第一风扇对蓄电池散热，第二风扇对LED灯头散热，形成两个独立的散热系统，此时从第三通孔进来的是冷风，并且经过LED灯头的气流风量更大，对LED灯头的散热效果更好。In the street lamp of the present invention, when the LED lamp holder is turned on, under normal circumstances, when the measured value of the temperature sensor is less than the set threshold, the temperature of the LED lamp holder is not too high. At this time, in order to avoid the high energy consumption of two cooling fans, as shown in Figure 1 As shown, the second fan is turned off, the first fan is turned on, the airflow generated by the first fan first passes through the battery, part of it goes out from the second through hole, and the other part continues upward through the third round hole and passes through the LED lamp head to take away the heat (when the airflow It is heated when passing through the battery, so the heat dissipation effect on the LED lamp head is slightly worse); when the measured value of the temperature sensor is not less than the set threshold, the LED lamp head needs to strengthen heat dissipation at this time, so as shown in Figure 2, the first fan has a cooling effect on the battery For heat dissipation, the second fan dissipates heat to the LED lamp head to form two independent heat dissipation systems. At this time, the cold air comes in from the third through hole, and the airflow passing through the LED lamp head has a larger air volume, which has a better heat dissipation effect on the LED lamp head.
