Led multi-chip bonding die and light strip using the same

A light strip made of LED multi-chip bonding die, wherein the strip comprises:

• a plurality of bonding die sections, wherein each section comprises 4 LED multi-chip bonding dies and a current-limiting resistor in series connection, and each bonding die section is connected in parallel;
• a strip-like circuit board, wherein one of the surfaces of the circuit board is divided into lower and upper parts by height;
• on the upper part is equipped with power terminal through-hole contacts, through-hole weld joints for current-limiting resistor and through-hole weld joints for connection cable of negative pole, while on the lower part is equipped with a pad for power electrode of a plurality of LED multi-chip bonding dies;
• heat-dissipating copper sheet is equipped on the part of another surface of the circuit board where it is placed back-to-back with the electrode of the LED power;
• the LED multi-chip bonding dies for each bonding die section are installed at certain interval on the LED power electrode of the circuit board, wherein the positive and negative poles of the LED multi-chip bonding dies are connected with the through-hole contacts of the power terminal and the through-hole weld joints of the connection cable of negative pole, respectively;
• and the current-limiting resistor is welded with the through-hole weld joint of the current-limiting resistor and is connected between the two LED multi-chip bonding dies connected in series in each bonding die section.
