LED module

摘要

A lead 1 includes a die-bonding portion 11 with an opening 11a penetrating in a thickness direction. Another lead 2 is spaced from the lead 1. An LED unit 3 includes an LED chip 30 with a electrode terminal 31 connected to the lead 1 and another electrode terminal 32 connected to the lead 2. The LED unit 3, mounted on a surface of the die-bonding portion 11 on a first side in z direction, overlaps the opening 11a. A wire 52 connects the lead 2 and the electrode terminal 32. A support member 4 supporting the leads 1-2 is held in contact with another surface of the die-bonding portion 11 on a second side in z direction. These arrangements ensure efficient heat dissipation from the LED chip 30 and efficient use of light emitted from the LED chip 3.

1. An LED module comprising:
a first lead including a die-bonding portion formed with an opening penetrating in a thickness direction; a second lead spaced apart from the first lead; an LED unit including an LED chip provided with a first electrode terminal and a second electrode terminal, the first electrode terminal being electrically connected to the first lead, the second electrode terminal being electrically connected to the second lead, the LED unit being mounted on a surface of the die-bonding portion disposed on a first side of the die-bonding portion in the thickness direction; a wire connecting the second lead and the second electrode terminal to each other; and a support member supporting the first and the second leads and held in contact with a surface of the die-bonding portion disposed on a second side of the die-bonding portion in the thickness direction; wherein the opening is smaller than the LED chip as viewed in the thickness direction, and the opening is covered entirely by the LED chip as viewed in the thickness direction, wherein the opening is filled with a part of the support member, and wherein the support member is made of a white resin.
