an output end e5 of the first color temperature lamp plate control chip U5 is electrically connected with a first end of the first color temperature lamp plate L1 and a first end of the second color temperature lamp plate L2 respectively; an output end f8 of the second color temperature lamp plate control chip U6 is electrically connected with a second end of the first color temperature lamp plate L1 and a second end of the second color temperature lamp plate L2 respectively;

wherein, the clock signal of the first clock signal control end c10 of the MCU module U3 is opposite to the level of the clock signal of the first clock signal output end d6 of the clock control chip U4; the clock signal at the second clock signal control end c13 of the MCU module U3 has the opposite level to the clock signal at the second clock signal output end d3 of the clock control chip U4.

For example, when a barrier stays on the light emitting surface of the light emitting diode D1 and the sensing surface of the photo-transistor Q1, for example, when a human hand is placed on the light emitting surface of the light emitting diode D1 and the sensing surface of the photo-transistor Q1, the light emitting diode D emits light, the light is reflected to the photo-transistor Q1 by the human hand, the pulse signal output end c7 of the MCU module U3 continuously emits a pulse signal, and when a high level is output, the photo-transistor Q2 is turned on to output a high level signal; when the output low level is detected, the light-on triode Q2 is turned off, a low level signal is output, the infrared sensor 304 feeds the output high and low signals back to the infrared sensing receiving terminal c16 of the MCU module U3, and then the clock duty ratios of the first output end and the second output end of the infrared control circuit 303 are controlled through the clock control chip U4, the first color temperature lamp panel U5 and the second color temperature lamp panel U6, so that the first color temperature lamp panel L1 and the second color temperature lamp panel L2 are controlled to be turned on and turned off, and the effect of adjusting the color temperature is achieved. For example, the color temperature of the first color temperature lamp panel L1 is 3000K, the color temperature of the second color temperature lamp panel L2 is 6000K, and the color temperature of the final light emission of the lamp can be between 3000K-6000K by adjusting the duty ratio of the light emission period of the first color temperature lamp panel L1 and the duty ratio of the light emission period of the second color temperature lamp panel L2.

For another example, when the duration of the human hand on the light emitting surface of the light emitting diode D1 and the sensing surface of the phototransistor Q1 is less than the preset time, the infrared control circuit 303 controls the first color temperature lamp panel L1 and the second color temperature lamp panel L2 in the lamp panel 12 to turn on or off. When the duration time of the human hand on the light emitting surface of the light emitting diode D1 and the sensing surface of the phototriode Q1 is greater than or equal to the preset time, the clock duty ratios of the first output end and the second output end of the infrared control circuit 303 are controlled, the lamp panel 12 enters a color temperature adjusting mode until the human hand is taken away, and the color temperature of the lamp panel keeps the color temperature corresponding to the moment when the human hand is taken away.
