具体实施方式
下面参考附图对本发明的优选实施例进行描述。
如图 1—4所示, 本发明实施例提供了一种背光模组, 包括光源 1、 散热 装置 2以及前框 3, 所述光源 1装设在所述散热装置 2上, 所述前框 3包括 至少一个限位部, 所述限位部将所述光源 1紧固在所述散热装置 2上。 具体 的, 前框 3包括互成一定角度的横板 31和竖板 32, 散热装置 2设置在竖板 32的内侧, 光源 1装设在散热装置 2远离竖板 32的一侧, 限位部设置在横 板 31的内壁上。
本发明的背光模组通过在前框 3上设置限位部,使光源 1能够与散热装 置 2紧密接触, 光源 1产生的热量能够由散热装置 2迅速传递到外部, 提升 了散热装置 2的散热效率, 有利于背光模组更高效地散热。 以下具体说明背 光模组的结构。
其中, 散热装置 采用铝挤或其他材料的型材, 光源 1可以采用 LED 与 MCPCB ( Metal Core PCB, 金属基印刷电路板)进行封装形成 LED灯条 的形式, 通过胶带或螺丝等方式固定在散热装置 2的内侧壁上。
第一实施例:
请具体参照图 1所示, 本实施例的背光模组具有光源 1、 铝挤 2以及前 框 3。
前框 3设置在铝挤 2的邻侧, 其具有的限位部在本实施例中为一条凸设 在前框 3的横板 31的内壁上的凸棱 33。 当组装前框 3在背光模组上时, 该 凸棱 33抵压在光源 1上, 使光源 1与铝挤 2相紧固。 这样, 就能够使光源 1 和铝挤 2保持紧密接触的状态, 发挥铝挤 2的导热效能。 本实施例中, 该凸 棱 33并不与该背光模组的光学部材 4相接触, 这样可以减少对光学部材 4 的影响。
本实施例中, 凸棱 33设置的位置可以根据光源 1和铝挤 2的厚度进行 调整, 只要满足在装配前框 3时, 凸棱 33可以抵压在光源 1上。
第二实施例:
请具体参照图 2所示, 本实施例中, 限位部仍采用上述第一实施例中凸 棱的结构(本实施例中标号为 34 ), 凸棱 34设置在横板 31的内壁上。 此外,
在光源 1与光学部材 4之间形成用于容纳上述凸棱 34的凹腔 5。 光学部材 4 从上至下包括扩散板, 棱镜, 扩散板, 导光板等。 光学部材 4安装在光源 1 的发光侧。
当组装前框 3在背光模组上时, 凸棱 34位于光源 1与光学部材 4之间 形成的凹腔 5中。 凸棱 34具有两个斜面, 其中一个斜面抵压在光源 1上, 其另一斜面抵压在光学部材 4上, 从而使光源 1与铝挤 2相紧固。 这样, 光 源 1和铝挤 2之间能够保持紧密接触的状态, 发挥铝挤 2的导热效能。 这种 两面抵压的方式可以使抵压效果更稳固。 由此可见, 本实施例与第一实施例 的不同之处在于, 本实施例中凸棱 34是分别与光源 1和光学部材 4相接触 的; 而第一实施例中凸棱 33只与光源 1相接触, 并不与光学部材 4相接触。
本实施例中, 凸棱 34设置的位置可以根据光源 1和铝挤 2的厚度进行 调整, 只要满足在装配前框 3的过程中, 凸棱 34可以容纳到上述凹腔 5中, 并且可以分别 4氏压在光源 1和光学部材 4上即可。
上述第一和第二实施例在具体实施时, 凸棱经沖压就可以在前框 3上形 成, 制成工序筒单, 也利于成本控制。
第三实施例:
请具体参照图 3所示, 本实施例与第一实施例不同之处在于, 限位部体 现为凸柱 35。 该凸柱 35抵压在光源 1上, 使光源 1与铝挤 2相紧固。 这样, 就能够使光源 1和铝挤 2保持紧密接触的状态, 发挥铝挤 2的导热效能。 本 实施例中, 该凸柱 35并不与该背光模组的光学部材 4相接触, 这样可以减 少对光学部材 4的影响。
本实施例中, 凸柱 35设置的位置可以根据光源 1和铝挤 2的厚度进行 调整, 只要满足在装配前框 3时, 凸柱 35可以抵压在光源 1上。
第四实施例:
请具体参照图 4所示, 本实施例与第三实施例一样, 限位部体现为凸柱 36。 凸柱 36位于光源 1与光学部材 4之间形成的凹腔 5中。 凸柱 36—侧抵 压在光源 1上, 其另一侧抵压在光学部材 4上, 从而使光源 1与铝挤 2相紧 固。 这样, 光源 1和铝挤 2之间能够保持紧密接触的状态, 发挥铝挤 2的导 热效能。 这种两侧 4氏压的方式可以使 4氏压效果更稳固。 本实施例与第三实施
例的不同之处在于, 本实施例中凸柱 36是分别与光源 1和光学部材 4相接 触的; 而第三实施例中凸柱 35只与光源 1相接触, 并不与光学部材 4相接 触。
本实施例中, 凸柱 36设置的位置可以根据光源 1和铝挤 2的厚度进行 调整, 只要满足在装配前框 3的过程中, 凸柱 36可以容纳到上述凹腔 5中, 并且可以分别 4氏压在光源 1和光学部材 4上即可。
在前述第一至四的各实施例中, 凸棱或凸柱并不限于呈整条状的形式, 也可以设置为在前框 3的横板 31 内壁上多个间隔的凸棱或凸柱, 这些凸棱 或凸柱位于同一直线上。凸棱或凸柱的形状亦可以采用多种形式,只要满足: 在第一和第三实施例中该凸棱或凸柱能够抵压在光源 1上; 在第二和第四实 施例中该凸棱或凸柱能够分别抵压在光源 1和光学部材 4上。
本发明还公开了一种液晶显示装置, 该液晶显示装置包括上述任一实施 例中的背光模组, 具体实施方式不再赘述。
实施本发明的背光模组及采用该背光模组的液晶显示装置, 具有如下有 益效果: 通过在前框上设置限位部, 使光源能够与散热装置紧密接触, 光源 产生的热量可由散热装置迅速传递到外部, 提升了散热装置的散热效率, 有 利于背光模组更高效地散热。
