Abstract

The invention discloses a direct downward backlight assembly comprising a frame, at least a lamp tube support, at least a lamp tube and an spreading board. The frame has a base board, on which at least one hole is provided, and the lamp tube support is clamped in the opening. The lamp tube support comprise a base and at least one support fastener. The base is located outside the frame and the support fastener is located on the base and passes the hole. The support fastener has a lamp tube chuck and a clamping part. The clamping part clamps in the hole, and the lamp tube chuck is for clamping the lamp tube. The spreading board is located above the lamp tube. In this way, the direct downward backlight assembly is furnished with steady quality and good assembling efficiency.

Description

Technical field [0001] The present invention relates to a light source assembly, and particularly relates to a direct type backlight assembly. Background technique [0002] With the advancement of modern video technology, liquid crystal display devices have been widely used on the display screens of consumer electronic products such as LCD TVs, mobile phones, notebook computers, personal computers, and personal digital assistants. However, since the liquid crystal display panel of the liquid crystal display device does not have a light-emitting function, it is necessary to arrange a backlight assembly on the back of the liquid crystal display panel to provide the surface light source required by the liquid crystal display panel, so that the liquid crystal display panel can achieve the display effect. [0003] FIG. 1A is a perspective exploded view of a conventional direct type backlight assembly, and FIG. 1B is a partial cross-sectional view of the direct type backlight assembly ...
