Abstract
A light-emitting device includes a number (N) of light-emitting units, a number (a) of first metal pads and a number (b) of second metal pads. Each of the light-emitting units includes a number (n) of light-emitting chips each having two distinct terminals, where N and n are integers and N>1, n>≥3. The numbers (a) and (b) are integers and a>1, b>1, and the terminals of each of the light-emitting chips are electrically connected to a unique combination of one of the number (a) of first metal pads and a number (b) of second metal pads, respectively. The numbers (N), (n), (a) and (b) satisfy the equation: a*b=n*N.
