It is understood that the first illumination device 20 can be provided with a desired number of different types and specifications of LED lamps.

The second illumination device 30 is used for providing illumination and forming a second illumination area 300. In this embodiment, the second lighting device 30 is provided with a plurality of white LEDs, a plurality of red LEDs, a plurality of yellow LEDs and a plurality of green LEDs, so as to generate white light, red light, yellow light and green light with different light intensities, thereby forming white light with different color temperatures. It is understood that the first illumination device 20 can be provided with a desired number of different types and specifications of LED lamps.

The control device 40 includes a central control unit 410 and a first control unit 420. The control device 40 is used for controlling the first lighting device 20 and the second lighting device 30 to be turned on or off.

Further, the central control unit 410 can be used to control and switch the initial states of the first and second lighting devices 20 and 30. In one embodiment of the present invention, the central control unit 410 sets the first lighting device 20 to be turned on and the second lighting device 30 to be turned off, and when the first control unit 420 is turned on, the first lighting device 20 is turned on and the second lighting device 30 is turned off. In another embodiment of the present invention, the central control unit 410 sets the second lighting device 30 to be turned on and the first lighting device 20 to be turned off, and when the first control unit 420 is turned on, the second lighting device 30 is turned on and the first lighting device 20 is turned off. In this embodiment, the central control unit 410 is a single-chip microcontroller, and it is understood that any integrated circuit capable of implementing the functions described in this embodiment may be adopted as the central control unit 410. The first control unit 420 may be located anywhere in the environment in which the downlight illumination system 10 is used, such as on a wall, or elsewhere, as desired. It is understood that the central control unit 410 may be any integrated circuit that can implement the functions described in the embodiment of the present invention.

Further, the first control unit 420 is connected to the central control unit 410, the first lighting device 20 and the second lighting device 30.
