Abstract
An LED human centric lighting device includes a substrate, an LED light emitting chipset and at least two blue light chipsets with different color temperatures arranged on the substrate, a fluorescent colloid and an enclosure. The LED light emitting chipset includes multiple LED light emitting chips, and each of the blue light chipsets includes multiple blue light emitting chips with same color temperature. Each of the blue light chipsets forms a color temperature light emitting area, and the different color temperature light emitting areas are separated by the enclosure. The substrate is provided with a control circuit for controlling light emission of the corresponding color temperature light emitting area, and the fluorescent colloid is arranged in the enclosure. The LED light emitting chip and at least two blue light emitting chips with different color temperatures are assembled in the device, which can reduce a volume of the device.
