面光源组件及具有其的冰箱

技术领域
本发明属于家用电器技术领域，尤其涉及一种面光源组件及具有其的冰箱。
背景技术
目前，冰箱的制冷间室的顶部照明灯已无法满足照明需求，因为其灯光仅能照亮部分空间，若搁物架上放置较多物品时就会遮挡灯光，间室的边缘或下部会出现暗影，不方便用户查找与拿取食物。
因此，现在有一种可设置在间室后壁的面光源组件，将导光板设置在间室后壁，使用光源竖直照射导光板，从而整块导光板上发出均匀柔和的光，可照亮整个间室。但是对于一些超宽冰箱来说，需要在导光板中间开设通孔，以将一些装置穿过通孔固定在间室后壁等。但是开设通孔之后，通孔周围的导光板上会出现过亮或过暗的部分，从而造成整个导光板上的光线不均匀，照明效果不好。

具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
应该理解，本文使用的例如“上”、“上方”、“下”、“下方”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。
如图1-3所示，介绍本发明的面光源组件的第一实施方式。在本实施方式中，所述面光源组件1设置在冰箱的制冷间室2内，所述面光源组件1包括：光源100及被光源100垂直照射的导光板200，所述光源100沿所述导光板200的第一侧边250设置；所述导光板200的前表面210设置多个导光点211。在本发明实施方式中，所述导光板200竖直设置在制冷间室2内并覆盖部分间室后壁，光源沿导光板200的上边缘设置并垂直照射导光板200。
目前，在冰箱内设置的面光源组件，其导光板一般为光学级的亚克力/PC板材，这种板材具有极高反射率且不吸光。在导光板的表面用激光雕刻等技术印上导光点，导光点为多个在导光板 表面的小凹陷。接着将光源竖直照射导光板，此时光线会照射到各个导光点。在导光点处，反射光会向各个角度扩散，最终由导光板表面射出。为了使整个导光板的均匀发光，一般会在导光板上设置各种疏密、大小不一的导光点。在本发明实施方式中，在导光板开设通孔之前，所述导光板上的导光点的变化规律为：沿远离光源的方向，导光点的直径逐渐增大，所述导光点的密度逐渐增大。
在本发明实施方式中，所述导光板200的中间位置竖直开设一通孔220，所述通孔220包括靠近所述光源100的上边缘221及远离所述光源100的下边缘222。在超宽冰箱中，若使用面光源组件用来照明，需要在导光板200的中间开设通孔220，以将一些装置(如悬臂搁物架等)穿过通孔固定在间室后壁等。在本发明实施方式中，所述通孔220开设在导光板200宽度方向的中线上，并偏下设置。
在本发明实施方式中，所述导光板200前表面210靠近所述通孔220上边缘221的位置设置第一区域230，所述第一区域230内的每个导光点231的直径小于所述第一区域周边区域内的每个导光点211的直径，所述第一区域230内的导光点231的密度小于所述第一区域230周边区域内的导光点211的密度。
当导光板开设通孔之后，光线传导会被通孔220的上边缘221所阻挡，在上边缘221附近的表面，光线无法继续向下传导，则在此区域内的亮度会比其周边区域的亮度更大。也就是说，在导光板200前表面210会形成一个第一区域230，在第一区域230内的亮度会比其周边区域的亮度更大，于是造成导光板200的亮度不均匀。因此，需要对第一区域230内的导光点231的直径及密度做调整。在本发明实施方式中，将第一区域内的每个导光点231的直径调整为小于所述第一区域周边区域内的每个导光点211的直径；将第一区域230内的导光点231的密度调整为小于第一区域230周边区域内的导光点211的密度。
在调整之后，则可使得第一区域230的亮度与其周边区域的亮度一致。进一步地，为了使第一区域230内的光线亮度均匀，在所述第一区域230内，各导光点231的直径也会变化，其变化规律为沿远离所述光源100的方向，导光点231的直径逐渐减小。
在本发明实施方式中，所述导光板200前表面210靠近所述通孔220下边缘222的位置设置第二区域240，所述第二区域240内的每个导光点241的直径大于所述第二区域周边区域内的每个导光点211的直径，所述第二区域内240的导光点241的密度小于所述第二区域240周边区域内的导光点211的密度。
当导光板开设通孔之后，光线会被通孔220的上边缘221所阻挡，造成光线无法继续向下传导。则在通孔220的下边缘222附近的表面，会出现一片暗影区域。也就是说，在导光板200 前表面210会形成一个第二区域240，在第二区域内无光线从而形成一片暗影，于是造成导光板200的亮度不均匀。因此，需要对第二区域240内的导光点241的直径及密度做调整。在本发明实施方式中，将第二区域内的每个导光点241的直径调整为大于所述第二区域周边区域内的每个导光点211的直径；将第二区域240内的导光点241的密度调整为大于第二区域240周边区域内的导光点211的密度。
在调整之后，则可使得第二区域230的亮度与其周边区域的亮度一致。同样地，为了使第二区域240内的光线亮度均匀，所述第二区域240内，各导光点241的直径也会变化，而其变化规律为沿远离所述光源100的方向，导光点241的直径逐渐增大。
进一步地，所述第一区域230为由通孔220上边缘221向上延伸的扇形，所述第二区域240为由通孔220下边缘222向下延伸的扇形。
为了保证整个导光板200的光亮均匀，在所述导光板200前表面210除所述第一区域230及所述第二区域240以外的区域上的导光点221的直径及密度的变化规律与导光板200开设通孔220之前的变化规律相同。
优选地，将所述第一区域230周边的一个区域定义为第一对比区域232，所述第一对比区域232与第一区域230的竖直高度及面积均相同。举例来说，在第一对比区域232内，其导光点211的平均直径为0.5mm，导光点211的密度为每平方厘米325个；此时，第一区域230内的导光点231的平均直径设置为0.2mm，导光点231的密度设置为每平方厘米152个。
同样地，将所述第二区域240周边的一个区域定义为第二对比区域242，所述第二对比区域242与第二区域240的竖直高度及面积均相同。举例来说，在第二对比区域242内，其导光点211的平均直径为0.2mm，导光点211的密度为每平方厘米152个；此时，第二区域240内的导光点241的平均直径设置为0.5mm，导光点241的密度设置为每平方厘米325个。当然，依据导光板的通光率和需求特性，以上参数也可调整，可通过多次试验获得。
需要说明的是，为了示意第一区域230中的导光点231的变化及第二区域240中导光点241的变化，图x中仅示出了第一区域230中的导光点231和第一对比区域232中的导光点211，以及第二区域240内的导光点241和第二对比区域242内的导光点211。实际上，本发明实施方式中，所述导光板200的前表面210的所有区域均设置有导光点，其他区域的导光点未图示。
在本发明实施方式中，所述面光源组件1还包括一补充光源110，所述导光板200包括与所述第一侧边250相对的第二侧边260，所述补充光源110沿所述导光板200的第二侧边260设置。在整个面光源的下边条设置与顶部一样的灯条，针对第二区域240的暗影进行光度补偿。
所述导光板200还包括与所述前表面210相对的后表面(未示出)；所述通孔220边缘设置 第一防撞框223，所述第一防撞框223从所述导光板200前表面210的通孔220边缘向所述通孔220延伸并包裹至所述导光板200后表面的通孔220边缘。在通孔的220的边缘设置第一防撞框223，则可遮挡光线反射的较亮的区域，同时也可以在将一些装置(如悬臂搁物架等)穿过通孔安装在间室后壁时，防止装置的连接结构碰撞导光板200而造成损坏。
所述导光板200还包括与第一侧边250相邻的两个第三侧边270，所述第三侧270边沿长度方向设置第二防撞框271，所述第二防撞框271从所述导光板200前表面210的边缘向所述第三侧边270延伸并包裹至所述导光板200后表面的边缘。在本发明实施方式中，所述第三侧边270为导光板200的左右两个侧边，在导光板200的左右侧边设置第二防撞框271，同样可以在第三侧边270周围的后壁安装一些装置(如悬臂搁物架)时，防止相应的连接结构碰撞导光板200而造成损坏。
在本发明实施方式中，所述面光源组件还包括与所述导光板层叠设置的扩散板以及反射片(未示出)，所述扩散板贴合所述前表面设置，所述反射片贴合所述后表面设置。扩散板以及反射片的结构及作用为现有技术，在此不再赘述。
本发明实施方式还公开了一种冰箱，包括制冷间室2，所述冰箱还包括上述的面光源组件1，所述面光源组件1安装于所述制冷间室2内。
在本发明实施方式中，所述制冷间室1内还包括至少两个并排设置的悬臂搁物架，所述悬臂搁物架后部的两端分别设置连接件；所述制冷间室1的后壁400对应所述通孔220的位置设置通孔固定件430，所述后壁400对应所述导光板200两侧的位置分别设置左侧固定件410及右侧固定件420；
在本发明实施方式中，所述制冷间室2内设置两个并排设置的悬臂搁物架，分别为第一悬臂搁物架310及第二悬臂搁物架320；所述第一悬臂搁物架310的后部相对的两端分别设置第一左连接件311及第一右连接件312，第一左连接件311与左侧固定件410连接，第一右连接件312与通孔固定件430连接。
相应地，所述第二悬臂搁物架320后部相对的两端分别设置第二左连接件321及第二右连接件322，第二左连接件321与通孔固定件430连接，第二右连接件322与右侧固定件420连接。所述第一悬臂搁物架310及第二悬臂搁物架320与通孔固定件430，所述左侧固定件410及所述右侧固定件420的连接处的高度均相同，以使第一悬臂搁物架310及第二悬臂搁物架320可以水平安装在制冷间室内。
由此，第一悬臂搁物架310及第二悬臂搁物架320可并排设置在制冷间室2内。
在本发明实施方式中，所述第一左连接件311、第一右连接件312、第二左连接件321及第 二右连接件322的结构相同，均为一卡扣件，卡扣件分别固定连接在各悬臂搁物架后部的两端。
所述左侧固定件410上设置卡槽401，所述第一左连接件311可与所述卡槽401卡扣或脱离连接，同样地，所述右侧固定件420上设置卡槽401，所述第二右连接件可以所述卡槽401卡扣或脱离连接；而所述通孔固定件430上设置卡槽402，所述第一右连接件312及第二左连接件321均可与所述卡槽402卡扣或脱离连接。从而，第一悬臂搁物架310及第二悬臂搁物架320可拆卸式地安装在制冷间室2的后壁400上。
进一步地，所述卡槽401为多个，并分别于竖直方向上间隔排布在所述左侧固定件410及所述右侧固定件420上。所述卡槽402也为多个，并于竖直方向上间隔排布在通孔固定件430上，每个所述卡槽402的高度均与每个所述卡槽401的高度一致。
将第一悬臂搁物架310的第一左连接件311及第一右连接件312，分别与所述左侧固定件410的卡槽401及通孔固定件的卡槽402卡扣连接，则即可将第一悬臂搁物架310安装到制冷间室2内。
将第二悬臂搁物架320的第二左连接件321及第二右连接件322，分别与所述通孔固定件的卡槽402及右侧固定件420的卡槽401卡扣连接，则即可将第二悬臂搁物架320安装到制冷间室2内，在安装时，将两个悬臂搁物架安装入同样高度的卡槽401及卡槽402内，则可保持两个悬臂搁物架的高度相同，并排水平设置。
当所述第一悬臂搁物架310的前端向上抬起时，第一左连接件311及第一右连接件312，分别与所述左侧固定件410的卡槽401及通孔固定件的卡槽402脱离连接，则所述第一悬臂搁物架310可沿竖直方向运动。
同样地，当所述第二悬臂搁物架320的前端向上抬起时，第二左连接件321及第二右连接件322，分别与所述通孔固定件430的卡槽402及所述右侧固定件410的卡槽401脱离连接，则所述第二悬臂搁物架320可沿竖直方向运动。
从而，在用户根据食物体积的不同需要调节搁物架所限定的空间的大小时，可将第一悬臂搁物架310及第二悬臂搁物架320的前端向上抬起，并在制冷间室内上下移动。确定所需要的空间大小之后，可将第一悬臂搁物架310的前端放平，并使得第一左连接件311及第一右连接件312分别与所述左侧固定件410的卡槽401及通孔固定件的卡槽402卡扣连接，将第二悬臂搁物架320的前端放平并使得第二左连接件321及第二右连接件322分别与所述通孔固定件的卡槽402及右侧固定件420的卡槽401卡扣连接，即可将两个悬臂搁物架固定在制冷间室内。
如图4所示，当所述连接件上的卡扣与所述通孔固定件的卡槽配接时，所述卡槽水平方向的尺寸大于两个所述卡扣水平方向上的尺寸之和。为了使第一悬臂搁物架310的第一右连接件312 及第二悬臂搁物架320的第二左连接件321均可以与所述通孔固定件430的卡槽402卡扣连接，则需要卡槽402的宽度大于第一右连接件312及第二左连接件321的在水平方向上的厚度之和。
综上所述，本发明实施方式的面光源组件1，通过调整导光板200的通孔220的上边缘221及下边缘222的导光点的直径及密度，使得第一区域230的光线不会太亮，第二区域240的光线不会出现暗影，使第一区域230及第二区域240与周围区域的光线亮度一致，最终可使整个导光板200的光线均匀，满足了冰箱整体照明效果。并且，通过在所述导光板200的第二侧边260设置补充光源110，针对第二区域240的暗影进行光度补偿。在通孔220的边缘设置第一防撞框223，可遮挡光线反射的较亮的区域，同时也可以在将一些装置(如悬臂搁物架等)穿过通孔安装在间室后壁时，防止装置的连接结构碰撞导光板200而造成损坏。在导光板200的左右侧边设置第二防撞框281，同样可以在第三侧边周围的后壁安装一些装置(如悬臂搁物架)时，防止相应的连接结构碰撞导光板200而造成损坏。同时，通过在制冷间室2的后壁400对应通孔220的位置设置通孔固定件430，并在后壁400对应面光源1两侧的位置分别设置左侧固定件410及右侧固定件420，则并排的悬臂搁物架后部的连接件可分别与通孔固定件430、左侧固定件410及右侧固定件420连接，以实现在制冷间室2内设置并排的悬臂搁物架。并且，悬臂搁物架后部的连接件为一卡扣件，可分别与通孔固定件430、左侧固定件410及右侧固定件420上设置的卡槽卡扣连接，从而悬臂搁物架可拆卸式安装在制冷间室内。通孔固定件430、左侧固定件410及右侧固定件420上于竖直方向间隔排布多个卡槽，则将悬臂搁物架抬起时可使连接件与卡槽脱离连接，并将悬臂搁物架在制冷间室内上下移动后再次将连接件与卡槽卡扣连接，从而悬臂搁物架的高度可调节，以适应不同体积的食物。本发明的冰箱，可实现面光源的均匀照明及并排悬臂搁物架的固定，解决了超宽冰箱的制冷间室在设置面光源时的左/右并排搁物架无处悬挂固定的问题。
