Abstract
An LED module 100 includes LED chips 21, 22 spaced apart from each other, and an LED chip 23 offset from a straight line connecting the LED chips 21 and 22 and located between the LED chips 21, 22 in the direction in which the LED chips 21, 22 are spaced. The module further includes a lead 31 with a bonding portion 31a and a mounting terminal surface 31d, a lead 32 with a bonding portion 32a and a mounting terminal surface 32d, and a lead 33 with a bonding portion 33a and a mounting terminal surface 33d. The mounting terminal surfaces 31d, 32d, 33d are flush with each other. Light from the LED chips 21, 22, 23 is emitted in the direction in which the mounting terminal surfaces 31d, 32d and 33d extend. Thus, light of different colors properly mixed can be emitted from a compact LED module.
