Abstract
The present invention provides a backlight module includes a light source, a heatsink, and a front frame. The light source is arranged onto the heatsink, and the front frame is provided with at least a limiting arrangement pressing the light source intimately seated onto the heatsink. The present invention further discloses a liquid crystal display device incorporated with the backlight module described above. With the provision of the limiting arrangement installed on the front frame of the backlight module, the light source can be securely and closely in thermal contact with the heatsink. As a result, the heat generated by the light source can be readily and effectively dissipated by the heatsink. With the performance of the heat dissipation increased, the light source installed on the backlight module can also be upgraded with their power. Further, the liquid crystal display device incorporated with such backlight module is also benefited.
