Abstract:
1. A light emitting module, comprising: a substrate having a cross-shaped central region and a peripheral region surrounding the cross-shaped central region; a plurality of first light emitting diode (LED) chips disposed on the substrate and at least located in the cross-shaped central region, wherein a dominant wavelength of the first LED chips is in a wavelength range of a specific color light, and a difference between the dominant wavelengths of at least two first LED chips is greater than or equal to 5 nm, and the first LED chips are blue LED chips having dominant wavelengths of 440-480 nm; and a plurality of second LED chips disposed on the substrate and at least located in the peripheral region, wherein a size of each second LED chip is smaller than a size of each first LED chip, the number of the first LED chips located in the peripheral region is smaller than the number of the first LED chips located in the cross-shaped central region, and the number of the second LED chips located in the cross-shaped central region is smaller than the number of the second LED chips located in the peripheral region, a dominant wavelength of the second LED chips is in a wavelength range of a specific color light, and a difference between the dominant wavelengths of at least two second LED chips is greater than or equal to 5 nm, the second LED chips are red LED chips having dominant wavelengths of 600-760 nm.
