A hanging ring 25 and a hanging piece 26 are also provided on the outer side of the back plate 20, which can facilitate the installation of the lamp.

[0036] In this embodiment, a control board 11, a wiring terminal 12 and a fan 13 connected to the control board 11 are provided inside the housing 10. The control board 11 is provided with five 0-10V output signals and one PWM output signal. The five 0-10V output signals are used to control the lamp board 30, and the one PWM output signal is used to control the fan 13.

[0037] In this embodiment, three fans 13 are provided. The three fans 13 are all installed on the back plate 20. An air inlet 21 is provided on the back plate 20, and an air outlet 31 is provided on the lamp board 30. The fans 13 blow external air from the air inlet 21 into the housing 10 and blow the hot air inside the housing 10 out of the housing 10 through the air outlet 31. An air outlet grille 22 is also provided on the outer wall of the housing 10 for discharging the hot air inside the housing 10. The plant lamp of this embodiment is provided with multiple fans 13 and air outlets 31 to timely remove the heat inside the lamp body and ensure the service life of the lamp as much as possible.

[0038] In this embodiment, five constant-current dimming power supplies 16 and one fan power supply 17 are further arranged inside the housing 10. The five constant-current dimming power supplies 16 are signal-connected to five 0-10V output signals through the terminal blocks 12. The output ends of the constant-current dimming power supplies 16 are connected to the lamp board 30. The fan power supply 17 is signal-connected to the PWM output signal through the terminal block 12, and the fan 13 is connected to the fan power supply 17. The five constant-current dimming power supplies 16 and the fan power supply 17 are also connected to the external AC power grid.

[0039] In this embodiment, an LED array is provided on the lamp board 30. The LED array is composed of five groups of lamp beads. The five groups of lamp beads are connected to the five constant-current dimming power supplies 16 in one-to-one correspondence, so that the five groups of lamp beads are connected in parallel to the control board 11. The five groups of lamp beads respectively adopt white light lamp beads, 390nm lamp beads, 450nm lamp beads, 660nm lamp beads and 730nm lamp beads. The white light lamp beads, 390nm lamp beads, 450nm lamp beads, 660nm lamp beads and 730nm lamp beads are evenly arranged in the LED array of the lamp board 30.

[0041] In this embodiment, as Figure 3 and Figure 4 shown, this page displays 6 channels currently, including 5 0-10V output signals and 1 PWM output signal. Among them, 1 PWM controls the fan 13, and 5 0-10V control the lamps. Each of the channels controlling the lamps can be individually timed on and off, and at the same time, the brightness of the 5 lamps can be adjusted together. Press the "ON / OFF" key to turn on or off the output signals of the 6 channels. This brightness can only be set by timing, cannot be adjusted manually, and can only be turned on and off manually. On the main page, pressing the "Return", "+", "-" keys has no action or function. Short pressing the "Channel Selection" key has no action or function. Dimming is adjusted by multiplying the coefficient based on the current duty cycle of all CHs, without changing the percentage setting and display of the current CH. For example: Dimming is 80%, CH1 is 30%, at this time, the percentage output by CH1 is 0.8 * 30% = 24%. The duty cycle of FAN is separate and does not multiply with Dimming.
