LED module and LED dot matrix display

摘要

An LED module A1 includes LED chips 3R, 3G, 3B, and a module substrate 1 on which the LED chips 3R, 3G, 3B are mounted. A wire 4R is connected to the LED chip 3R, and the LED chips 3G and 3B are arranged to face each other across the wire 4R. With this arrangement, the LED module A1 is reduced in size, and red light, green light and blue light are properly mixed.

主权项

1. An LED module comprising:
a first LED chip, a second LED chip and a third LED chip; a module substrate on which the first LED chip, the second LED chip and the third LED chip are mounted; a wiring pattern formed on the substrate and including a first pad connected directly to the first LED chip; and a first wire connected to the first LED chip; wherein the first LED chip, the second LED chip and the third LED chip are disposed at three vertexes of a triangle, respectively, and the first wire extends between the second LED chip and the third LED chip in a manner such that the first wire intersects a direction in which the second LED chip and the third LED chip are spaced apart from each other, wherein the wiring pattern further includes a second pad and a third pad both of which are spaced apart from the first pad, wherein the LED module further comprises a second wire and a third wire connected to the second LED chip and the third LED chip respectively, the second wire extends from the second LED chip and away from the first wire, and the third wire extends from the third LED chip and away from the first wire, wherein the second wire is attached to the second pad, and the third wire is attached to the third pad, and wherein the second LED chip, the third LED chip, the second wire, the third wire, the second pad and the third pad are arranged substantially on a common straight line.
