Abstract
The present invention discloses a backlight module, which includes a light source and an aluminum extrusion. The aluminum extrusion forms at least one thermal chamber. The thermal chamber is a penetrating hollow structure having an opening. The present invention also discloses a liquid crystal display device having the backlight module. Practicing the backlight module of the present invention and the liquid crystal display device using the backlight module allows a channel for air flow to be formed in the interior of the thermal chamber to enhance heat dissipation performance, eliminate the operations of forming a light bar through packaging the light source and an MCPCB and bonding the light bar to the aluminum extrusion, decrease thermal resistance interface, and saves assembling material.
