Light bar and backlight module

摘要

A light bar includes a wiring substrate, a plurality of light sources, and at least one high efficient heat-dissipating component. The wiring substrate has a first surface and a second surface opposite to the first surface. The second surface is divided into at least one high efficient heat-dissipating section and at least one low efficient heat-dissipating section. The light sources are respectively disposed on the first surface opposite to the high efficient heat-dissipating section and the low efficient heat-dissipating section. The high efficient heat-dissipating component is disposed on the high efficient heat-dissipating section.
