A circuit board (3) is electrically connected to the lower part of the lamp holder (1). A radiator (2) is disposed between the lamp holder (1) and the circuit board (3). An alarm layer is connected to the lower part of the circuit board (3). The alarm layer is sealedly connected to the lampshade. The alarm layer comprises a circuit board temperature probe (6) close to the circuit board (3) and comprises a buzzer (4). A lamp post temperature probe (7) is disposed in the lamp post (5). An alarm switch (8) is disposed on the outer side of the alarm layer. The lamp post (5), the circuit board temperature probe (6), the lamp post temperature probe (7) and the alarm switch (8) are all electrically connected to the circuit board (3). The LED lamp can automatically detect the temperature in the LED lamp and give an alarm, and can also turn off the alarm switch or a power supply according to conditions. |
