Abstract
A light emitting module including a substrate, a plurality of first light emitting diode (LED) chips and a plurality of second LED chips is provided. The substrate has a cross-shaped central region and a peripheral region surrounding the cross-shaped central region. The first LED chips are disposed on the substrate and at least located in the cross-shaped central region. The second LED chips are disposed on the substrate and at least located in the peripheral region. 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 that in the cross-shaped central region. The number of the second LED chips located in the cross-shaped central region is smaller than that in the peripheral region.
