Abstract:
The present invention is concerned with an LED packaging unit, a manufacturing method for the same, and an LED lamp. The LED packaging unit has a common substrate, N number of red LED chips, M number of green LED chips and X number of blue LED chips. The N number of red LED chips, the M number of green LED chips and the X number of blue LED chips are arranged and packaged on a bottom surface of a recess of the common substrate. The red LED chips, the green LED chips and the blue LED chips are all monochromatic LED chips, with N, M, and X being integers greater than 1. The distances between any adjacent two red LED chips (or green LED chips or blue LED chips) are substantially consistent.
