Because the intelligent probe is used for receiving the operation information of the lamp and transmitting the operation information to the intelligent module for processing the information, one or more detection probes such as a microwave probe, a temperature sensing probe, an infrared receiving probe and the like can be adopted. The intelligent probe in the embodiment is a microwave probe, the microwave probe can detect human body activities around the lamp, when the human body activities are around the lamp, the probe outputs information to the intelligent module, the intelligent module controls the power supply 9 to supply power and starts the driving motor 5, so that the light source plate 1 starts to emit light when being electrified, and the heat radiation body 4 starts to rotate to drive the convection of air inside and outside the lamp, so as to accelerate the heat radiation; when the probe detects that the human body activity around the lamp disappears, the probe sends a signal to the intelligent module, the intelligent module firstly controls the power supply 9 to stop supplying power to the light source plate 1, the driving motor 5 continues to work, and when the probe still does not detect the signal of the human body activity after the preset time is reached, the intelligent module controls the driving motor 5 to stop running again, so that the heat radiation body 4 stops rotating. The temperature sensing probe can be used for detecting the temperature in the lamp and sending temperature information to the intelligent module, the intelligent module controls the rotating speed of the driving motor 5 according to the temperature information, the rotating speed of the driving motor 5 is linearly related to the temperature in the lamp and accelerates along with the rise of the temperature, and particularly the driving motor 5 can be set to start to drive the heat radiator 4 to run at the lowest speed, such as 10 circles per minute after the lamp is powered on; as the lamp works, the internal temperature of the lamp begins to rise, the driving motor 5 also begins to accelerate, and the speed and the temperature are linearly related; when the temperature reaches a certain level, for example, over 80 degrees celsius, the driving motor 5 drives the heating body 4 to operate at a permissible maximum, for example, 100 revolutions per minute. If an infrared receiving probe is adopted, the lamp needs to be matched with a remote controller for use, data of an idle mode is preset in the intelligent module, the infrared receiving probe receives signals sent by a user through the remote controller, such as turning on the lamp, turning off the lamp, radiating in different modes and the like, and then transmits the signals to the intelligent module, and the intelligent module controls the power supply 9 and the driving motor 5 to operate according to instructions; for example, when a light-on signal is received, the intelligent module controls the power supply 9 to start supplying power, the driving motor 5 is started to drive the heat radiation body 4 to rotate at a preset rotating speed, such as 50 circles per minute, when a light-off signal is received, the intelligent module firstly controls the power supply to stop supplying power to the light source plate 1, and the driving motor 5 continues to work for a preset time, such as 1 minute after the light is turned off, and then stops running or directly stops running.
Different intelligent probes can be installed on the lamp according to different use environments and requirements in production, different modes are set for the intelligent module, and the intelligent module controls the lamp to operate according to data of the intelligent probes.
