Baby nursing apparatus and control method of blue-light irradiation intensity thereof

The invention relates to a baby nursing apparatus and a control method of blue-light irradiation intensity thereof. The baby nursing apparatus comprises an infanette, a circuit control assembly, a blue-light irradiation assembly, a first detector assembly and a second detector assembly. The collimating lens of the blue-light irradiation assembly can be moved to adjust the size of an irradiation light spot; the first detector assembly can detect position coordinates of each position of a baby in a two-dimensional coordinate system taking the center of the irradiation light spot as an original point and can transmit the position coordinates of each position of the baby to the circuit control assembly; the second detector assembly can detect the temperature of a blue-light lamp and obtain a temperature value; and the circuit control assembly can calculate the area of the irradiation light spot and, according to the area of the irradiation light spot, the temperature value and a preset irradiation intensity value, obtain driving currents so as to drive a blue-light source through the driving currents. The baby nursing apparatus provided by the invention can improve the utilization rate of blue light and can control the blue-light irradiation intensity according to the size of the irradiation light spot after adjustment.
