摘要:本申请提供一种直下式背光模组及LED阵列。所述背光模组包括:承载板;LED阵列,设置于承载板上,LED阵列包括LED光源;光学透镜,围绕LED光源,光学透镜包括LED光源发出之光线的入光面和出光面;调光结构,与承载板相距一段距离,调光结构和承载板之间定义出腔体;以及支撑结构,设置于光学透镜的出光面上,沿着背离承载板的方向,在腔体内向调光结构延伸,支撑结构用于支撑调光结构。本申请能够抑制暗影生成,提示支撑结构的结构强度。
Abstract:The invention provides a direct-light-type backlight module and an LED array. The backlight module comprises a bearing plate, the LED array, an optical lens, a dimming structure and a support structure. The LED array is arranged on the bearing plate and comprises an LED light source. The optical lens surrounds the LED light source and comprises a light-in face and a light-out face for a light rayemitted by the LED light source. A distance exists between the dimming structure and the bearing plate. a cavity is defined between the dimming structure and the bearing plate. The support structure is arranged on the light-out face of the optical lens, extends in the cavity towards the dimming structure in the direction away from the bearing plate, and is used for supporting the dimming structure. Through the direct-light-type backlight module and the LED array, shadow generation can be restrained, and the structure strength of the support structure is improved.
