Abstract: A lighting device and incubator for microalgae growth experiments. The device includes at least one light source having light emitting diodes for illuminating microalgae, and a control unit configured to control the switching on and off of the light emitting diodes and to vary the light intensity of the light emitting diodes. The light source includes RGB LEDs, and each RGB LED has a housing that houses a red light emitting diode, a green light emitting diode, a blue light emitting diode and a microcontroller that communicates with the control unit to vary the light intensity of the red light emitting diode, the green light emitting diode and the blue light emitting diode of the RGB LED, such that the color and intensity of the light emitted by each RGB LED are modified by the control unit.
