摘要： The present application involves in the field of electronic circuit technologies, and particularly to a smart lamp and its light and color adjustment circuit connected to a light emitting module. The light emitting module includes a string of green LEDs and a string of red LEDs, and further includes a first string of blue LEDs and a second string of blue LEDs emitting light with different preset wavelengths. The light and color adjustment circuit includes an induction circuit, a filter circuit, a radio frequency circuit and a control circuit, and outputs an induction signal through acquiring illumination intensity of a surrounding preset area, and filters the induction signal to acquire a feedback signal, and finally adjusts luminous flux of the first string of blue LEDs, the second string of blue LEDs, the string of green LEDs and the string of red LEDs according to the feedback signal, so as to synthesize a multiple modes of spectra. As a result, the brightness and color of the smart lamp can be adjusted, strengthen or weaken, according to different illumination intensity, which realizes a full spectrum mode, improves the user experience, and solves the problems that the existing lamps cannot realize the full spectrum mode and are provided with a relatively single light-emitting mode.

摘要： A lighting apparatus includes a LED module (661) and a driver (669). The LED module includes a first LED chip (662), a second LED chip (663), a first fluorescent layer (664), a second fluorescent layer (665) and a package frame (6610). The first LED chip and the second LED chip are respectively disposed at a first area (6612) and a second area (6611) of the package frame. The first fluorescent layer covers the first area. The second fluorescent layer covers the second area. The first fluorescent layer and the second fluorescent layer have different types of fluorescent materials. The driver (669) generates a driving current (6613) supplied to the LED module (661) so that the LED module emits a first light (6615) above the first area and a second light (6614) above the second area for generating a mixed light (6616) from the first light and the second light.
