Description

一种可预设铺光效果的画相框 技术领域
本发明涉及画框/相框领域，具体涉及一种可预设铺光效果的画相框，对现有铺光相框铺光质量有实质性的增强和改进。
背景技术
铺光画相框作为画相作品的承载和陪衬，有两个非常重要的指标：铺光效果和画相框整体的纤薄程度，铺光的理想效果是画相作品呈现出中间位置的亮度稍微高于四周以衬托出画相作品的展示主题，或者画相作品整体表面的光线均匀铺射。为了达到这种效果，目前常用的手段都是通过在画框外设置射灯直接对画相框投射光线。
现有的内发光画相框结构都是由设置在画相框内视窗外围的光源发光向视窗中心投射光线，底板或画相作品设置在底部，从而光线铺射在底板或画相作品的表面。(如专利号：2020201106663所述技术方案)
现有的内发光画相框技术方案在实际应用中有个不可避免的缺陷：由于光线是从视窗外围的四周向视窗中间的聚光槽投射光线，底板或画相作品表面有明显的光斑效应和亮度分界线，即离光源远的中央位置大部分面积的亮度暗而靠边缘离光源近的周边面积明显亮(界内比较忌讳的铺光效果)，导致不能完美衬和展示托画像作品的整体艺术效果。
发明内容
本发明的目的在于提供一种可预设铺光效果的画相框，确保画相作品靠中 央部分表面的铺光强度和周边部分表面的铺光强度是可设置的，可以根据需要使画相作品表面的铺光达到更佳视觉效果。
基于上述目的，本发明提供的一种可预设铺光效果的画相框，包括投光件、上导光檐和下导光檐；
由上下设置并间隔一定距离的所述上导光檐和所述下导光檐构成横向铺光通道，并对接所述投光件；由至少包含一段铺光方向向内的所述横向铺光通道围成中间的聚光槽；所述投光件设置在所述聚光槽外围，使所述下导光檐至少有一部分位于所述投光件与所述聚光槽之间，形成檐状结构，所述投光件发出的光线经过与其对应的所述檐状结构上方并向所述聚光槽以及位于所述聚光槽下方的空间投射光线。
其中，所述上导光檐和所述下导光檐之间的上下位置关系为基于纵向方向的位置关系，包括两者纵向投影面积之间至少有交集或者完全没有交集的位置关系。构成横向铺光通道的必要条件之一是必须对接有相应的投光件，没有对接投光件的上导光檐和下导光檐不能称为横向铺光通道；所述横向铺光通道与所述投光件对接是指所述投光件发出的光线能经过所对接的横向铺光通道向所述聚光槽方向(即铺光方向向内)横向投射光线。

进一步的，所述闭合铺光结构的所述聚光槽形状为矩形或者三角形或者其它多边形或者圆形或者椭圆形或者心形或者扇形。所述闭合铺光结构的聚光槽相当于一段铺光方向向内且首尾相连的所述横向铺光通道围合而成。
进一步的，还包括底板，所述底板位于所述聚光槽的下方，即所述聚光槽的纵向投影面积与所述底板至少有交集部分，使所述檐状结构表面至少有一部分高于位于所述聚光槽纵向投影面积内的所述底板表面，使向所述聚光槽下方空间投射的所述光线铺射在所述底板表面。
进一步的，所述檐状结构靠近所述聚光槽一侧的外缘与所述投光件之间的距离不小于所述檐状结构正表面的最高处与所述上导光檐背面之间的纵向距离；
所述聚光槽下方的所述底板表面与所述檐状结构正表面最高处之间的纵向距离不小于所述檐状结构正表面最高处与所述上导光檐背面之间的纵向距离。

所述上导光檐为水平檐或斜坡檐或弧形檐或台阶檐；
所述上导光檐和所述下导光檐的形状设置有利于实现不同的铺光效果。
进一步的，所述投光件侧向发光，发光方向朝向所述聚光槽，直接向所述聚光槽投射光线；或者，
所述投光件纵向发光，通过所述上导光檐背面和所述下导光檐正面两者中至少一个的反射和散射间接向所述聚光槽投射光线。
进一步的，所述底板与所述檐状结构为一体结构。
进一步的，与所述底板为一体结构的所述檐状结构为台阶状或凸起状。
进一步的，所述投光件和所述檐状结构为一体结构，即所述投光件自带所述檐状结构。
进一步的，还包括画相外框，所述上导光檐的外缘设置在所述画相外框的正面框檐下；或者，

进一步的，所述上导光檐设置有镂空透光图案。
进一步的，还包括画相作品，所述画相作品设置在所述底板表面；或者，
所述画相作品本身就是底板；

所述上导光檐设置在所述透明保护层的上方；
所述透明保护层的纵向投影面积覆盖所述上导光檐的全部面积和部分面积两者中的一种面积，并且覆盖所述聚光槽槽口的全部面积。
进一步的，所述透明保护层为单向玻璃或者覆有单向膜的玻璃，即能从正面看到其背面(后方)的景象，反向则不行，设置在所述透明保护层下方的所述投光件发光，一部分光被封盖在所述聚光槽正面槽口处的具有单向透光特征的所述透明保护层反射到所述聚光槽下方，提升铺光亮度和质量。
进一步的，还包括横向透光罩，所述横向透光罩横向封盖所述横向铺光通道靠近所述聚光槽的一侧，所述横向透光罩用来保障所述横向铺光通道内的清洁。
本发明中的技术方案和关键特征是在现有内铺光画相框的技术方案实施调试过程中意外发现的。意外发现：在包含有横向相对投射光线的聚光槽结构中，在投光件下方与底板表面之间设置向聚光槽方向延伸出的针对投光件的檐状结构，能特别有效的解决现有铺光画相框技术方案无法解决的技术问题以及与实际应用要求之间的矛盾，即现有技术方案中底板表面明显的光斑和亮度分界线问题以及整体厚度和铺光均匀质量之间的矛盾。
在实验中意外发现，檐状结构的宽度以及上导光檐和檐状结构两者之间的纵向距离乃至两者之间相对宽度和面积的设置是影响铺光效果的重要因素，檐状结构的宽度以及横向铺光通道的纵向高度发生变化，底板表面中央部分相对亮度和相应亮度面积会跟着变化；上导光檐相对檐状结构的宽度和面积发生变化，底板表面周边部分相对亮度和相应亮度面积也会跟着变化。
设置下导光檐的檐状结构是解决现有铺光画相框铺光质量以及光斑问题的关键特征，通过本技术方案的实施达到的效果如下：
1，根据具体铺光需求用带有一定宽度的檐状结构的扁平状横向铺光通道构成的相应的聚光槽结构(各种非闭合铺光结构和闭合铺光结构)能有效的实现对底板表面不同区域铺光效果的设置，可以实现多种特殊的画相作品表面铺光效果，比如均光效果、中间稍亮边缘稍暗的突出主题效果、指定某个区域稍亮的效果以及非对称的亮度渐变效果等，对现有铺光画相框铺光质量有实质性的增强和改进。
2，在保证底板表面铺光均匀度的前提下，本技术方案实施的画相框相比于现有技术方案，整体厚度可以至少减少80％，即至少用五分之一的厚度实现相同铺光均匀度。同时，铺光的光照强度(即亮度)却大大增加了；
3，上导光檐除了用来遮盖从正面观看时投光件或/和其他不必要发光的部位对视觉造成不必要光线干扰外，还配合下导光檐，使其与下导光檐的檐状结构配合构成扁平状的横向铺光通道，保证更多的光线横向投射到底板表面；更重要的是，在下导光檐的檐状结构能单独实现意外的均匀铺光效果的基础上，作为檐状结构的辅助结构，通过设置和调节上导光檐在聚光槽内的延伸宽度和面积，可以再次意外的对画相作品表面的铺光效果进行更细腻的二级设定和调整，使铺光效果更趋于完美。

具体实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例
如图1A和图1B，本实施例提供聚光槽10的形状为矩形的一种可预设铺光 效果的画相框，包括：投光件、上导光檐4和下导光檐3。
聚光槽10为矩形的闭合铺光结构，相当于由一段铺光方向向内且首尾相连的所述横向铺光通道围合而成的矩形聚光槽10；横向铺光通道由上下间隔一定距离设置的上导光檐4和下导光檐3构成，横向铺光通道内部设置有投光件(即下导光檐3设置在投光件下方，上导光檐4设置在投光件上方，投光件位于聚光槽10的外围)，即投光件与横向铺光通道对接。
其中，投光件为由LED带状光源1和横向设置的透明导光板5组合的发光结构，LED带状光源1侧向发光并设置在透明导光板5开设的凹槽内，并围绕矩形的聚光槽10一周，LED带状光源1发光方向朝向聚光槽10。投光件设置在横向铺光通道内，使下导光檐3在靠近聚光槽10一侧形成檐状结构2，即檐状结构2为下导光檐3位于投光件与聚光槽10之间的部分。
此实施例中，上导光檐4和下导光檐3都是水平檐；檐状结构2的宽度(即投光件与下导光檐3靠近聚光槽一侧外缘之间的距离)不小于横向铺光通道的高度(即上导光檐4和檐状结构2之间的纵向距离)；上导光檐4从正面完全遮盖投光件，并且上导光檐4的面积小于下导光檐3的面积，且上导光檐4遮盖檐状结构2的部分面积，使下导光檐3上的檐状结构2靠近聚光槽一侧的部分外露，从正面看，看不到投光件，能看到上导光檐4、中间镂空的矩形聚光槽10以及檐状结构2的外露部分(即与矩形的聚光槽10相对应的矩形环形状)。
当LED带状光源1发光时，光线进入透明导光板5的内部全反射横向传输，并从透明导光板5靠近聚光槽10的侧端面散射出来，散射出来的光线纵向的发散角度大，散射的光线经过檐状结构2上方的横向铺光通道时，光线的散射角度受到上导光檐4背面和檐状结构2正面的上下“挤压和导向”，光线的传输方向和投射特征发生变化。来自聚光槽10四周的横向铺光通道投射出来的光线集中向聚光槽10投射，并能更均匀的投射到聚光槽10下方的空间。如果没有设置檐状结构2，散射出来的光线投射到聚光槽10下方的空间时，光线产生不均匀的严重光斑，聚光槽10下方空间的周边亮度会明显高于靠近中央的区域亮度。
进一步的，如图1C所示，与图1B所示结构不同的是，投光件为由LED带状光源1与非透明的透光材料6组合的发光结构，其中，LED带状光源1设置在横向U型的箱体内并侧向发光，非透明的透光材料6封盖在U型箱体的开口处，形成一个横向发光箱体，箱体的上侧壁为上导光檐4，下导光檐3设置在横向U型发光箱体的下方，并朝聚光槽10的方向延伸出檐状结构2，因为横向U型发光箱体内的LED带状光源1发光通过U型箱体的开口处的非透明的透光材料6后，投射出来的光线具有大散射角度的特征，所以需要设置下导光檐3来提供檐状结构2。
可选的，横向U型发光箱体的下侧壁可以与下导光檐3为一体结构，这样，上导光檐4与下导光檐3为一体结构，分别为U型箱体的上下两个侧壁，作为下导光檐的下侧壁应向聚光槽方向延伸出檐状结构。
可选的，可以在横向U型发光箱体(即横向铺光通道)的内壁相应位置覆有反光层。
进一步的，在横向U型发光箱体的上侧壁(即上导光檐4)设置镂空透光图案，在横向铺光通道内传输的光线可以通过镂空透光图案透露出发光图案，可以从正面观看到透光的图案，对整体铺光效果起到装饰的效果。
进一步的，如图1D所示，与上述实施例结构主要不同的是，LED带状光源1本身就是投光件，LED带状光源1设置在下导光檐3的正表面，并且纵向向上发光；还包括横向透光罩12，横向透光罩12为透明材料且横向封盖在横向铺光通道靠近聚光槽的一侧，横向透光罩12用来保障横向铺光通道内的清洁。LED带状光源1发出的光线通过横向的U型箱体内壁(即横向铺光通道)的反射和散射，并经过横向透光罩12间接的投射到聚光槽10的下方空间。此结构中，透明材料的横向透光罩12没有改变穿过其厚度方向的光线的传输方向和角度，即没有引发光线散射，故其不是投光件的一部分。另外，此结构中，可以看作是上导光檐4和下导光檐3为一体结构的特殊实施例。另外，此结构中，上导光檐4遮盖檐状结构2以及整个下导光檐3的全部面积。
进一步的，如图2所示，与图1B所示结构主要不同的是，还包括底板7和画相作品8，其中，画相作品8设置在底板7表面，且位于底板7的中央位置，底板7和画相作品8设置在聚光槽10的下方，聚光槽10的纵向投影面积覆盖画相作品8的面积，檐状结构2通过台阶状结构与底板7结合为一体结构，即与7底板为一体结构的檐状结构2为台阶状，通过台阶状结构使底板7形成凹陷状，画相作品8设置在底板7的凹陷状结构底部，从而保障檐状结构2高于位于聚光槽10下方的画相作品8表面，并且画相作品8表面与檐状结构2表面之间的纵向距离不小于檐状结构2表面与上导光檐4背面之间的纵向距离。向聚光槽10下方空间投射的光线最终铺射在所述画相作品8的表面。画相作品8可以为绘画书法作品或者相片或者印刷品或者针织刺绣作品或者雕刻作品或者古董收藏作品或者带有发光图案的基板。可选的，画相作品与底板为一体结构，即画相作品本身就是底板或底板本身就是画相作品。
还包括画相外框9，上导光檐4和下导光檐3(即底板7的周边外缘)以及投光件三者都设置在画相外框9的正面框檐下，画相外框9有装饰以及稳固整体结构的作用。
还包括透明保护层11，透明保护层11为透明材料，透明保护层11设置在上导光檐4的上方，透明保护层11从正面覆盖上导光檐4的全部面积以及聚光槽10的整个槽口面积。透明保护层11起到保持聚光槽10内清洁的作用。
可选的，上导光檐4可以设置在透明保护层11的上方。
进一步的，透明保护层11为单向玻璃或者覆有单向膜的玻璃，即能从正面看到其背面(后方)的景象，反向则不行或反向透光性能小于正向透光性能，设置在透明保护层11下方的投光件发光，一部分光被聚光槽10正面槽口处的具有单向透光特征的透明保护层11反射到聚光槽10下方，提升铺光亮度和质量。
另外，图2所示的结构中，投光件是由LED带状光源1与横向设置的透明导光板5以及非透明的透光材料6三者组合的发光结构，其中，在透明导光板5 上开设的用来放置LED带状光源1的槽为通透槽，对比于图1B所示结构中的投光件，在透明导光板5的出光侧端面对接非透明的透光材料6，起到均光效果，因为如果没有对接非透明的透光材料6，从透明导光板5出光的侧端面能看到LED带状光源1的光斑，即能看到LED带状光源1上每个LED灯珠，因为透明导光板5是透明材料；对接非透明的透光材料6后，就看不到LED灯珠了，并且整个非透明的透光材料6均匀发光。而且，对比图1B所示结构，图2所示结构的檐状结构2的宽度(即檐状结构2靠近聚光槽10一端的外缘与投光件之间的距离)明显加宽，意味着从投光件的非透明的透光材料6散射出来的光线在横向铺光通道内传输的距离更长，这样会使光线在画相作品8表面的铺光均匀度和效果更佳。
进一步的，如图3所示，与上述实施例结构主要不同的是，投光件中的LED带状光源1设置在画相外框9的内侧壁上，侧向发光并直接向非透明的透光材料6投射光线；与底板7为一体结构的檐状结构2为另一种台阶状，如图3所示；台阶状的檐状结构2上有一部分明显高于位于聚光槽10的纵向投影面积内的底板7表面，并且聚光槽10下方的底板7表面与台阶状檐状结构2最高处之间的纵向距离不小于台阶状檐状结构2最高处与上导光檐4背面之间的纵向距离。此结构中的台阶状檐状结构2中向上隆起的台阶部分遮挡了一部分从投光件向聚光槽10直接投射的光线，同时减少了横向铺光通道的高度；此结构说明可以通过在檐状结构2靠近聚光槽10的位置设置高度较高部分(即凸起的台阶)以及其与投光件之间的距离来调节铺光效果：凸起的台阶高度与铺光均匀度成正比；隆起的台阶与投光件之间的距离(即与非透明的透光材料6之间的距离)与铺光均匀度成正比。另外，此结构中的下导光檐3为台阶檐；上导光檐4和下导光檐3(即底板7外缘)以及投光件中的LED带状光源1都设置在画相外框9的正面框檐下。
可选的，图3所示结构中，投光件可以为单独的LED带状光源1，即不设置非透明的透光材料6，LED带状光源1发光通过横向铺光通道直接投射到聚光槽 10中以及其下方空间的底板7表面。
进一步的，如图4所示，与上述实施例结构主要不同的是，与底板7为一体结构的檐状结构2为凸起状，凸起状的檐状结构2顶部表面高度高于聚光槽10下方的底板7表面，并且聚光槽10下方的底板7表面与凸起状檐状结构2最高处之间的纵向距离不小于凸起状檐状结构2最高处与上导光檐4背面之间的纵向距离，保证向聚光槽10下方的底板7表面铺射的光线都是经过凸起状的檐状结构2的上方投射的。此结构中的凸起状的檐状结构2所起到的效果和作用与图3所示结构中的台阶状檐状结构类似。此结构中，与底板7为一体结构的下导光檐3(包括凸起状的檐状结构2)为台阶檐。另外，画相外框9的正面框檐充当了上导光檐4的角色，即画相外框9的正面框檐与上导光檐4为一体结构。
进一步的，如图5所示，与上述实施例结构主要不同的是，投光件和檐状结构2为一体结构，即投光件中的非透明的透光材料6自带檐状结构2。其中，檐状结构2的宽度不小于投光件的高度，如图5所示。此结构中，檐状结构2也是下导光檐3，投光件设置在聚光槽10的外围并且也设置在下导光檐3的外围，即投光件不在下导光檐的正上方，但投光件发出的光线要经过檐状结构2的正上方。此结构中，底板7周边部分从下方向上抵住投光件底部以及部分檐状结构2的底部，起到图2所示结构中的下导光檐一部分作用，只不过与檐状结构2不是一体的；另外，上导光檐4遮盖檐状结构2(即下导光檐)的全部面积，从正面观测，视觉上只能看到画相外框9的正面框檐和上导光檐4以及聚光槽10范围内的底板7表面，而看不到投光件和檐状结构2。
可选的，与非透明的透光材料6为一体的檐状结构2的背面可以覆有遮光涂层。
可选的，如图6所示，与上述实施例结构主要不同的是，上导光檐4为弧 形檐，下导光檐3为斜坡檐。
进一步的，如图7所示，与上述实施例结构主要不同的是，上导光檐4只遮盖投光件的部分面积，且不遮盖檐状结构2。外露的一部分投光件也是对整体的铺光效果起到辅助的装饰作用。
以上所述的实施例中，聚光槽10为矩形的由横向铺光通道向内围合成的闭合铺光结构，可选的，根据具体效果的需要，闭合铺光结构的聚光槽还可以设置为三角形或者圆形或者椭圆形或者其他多边形或者心形或者扇形。
进一步的，如图8所示，与上述实施例结构主要不同的是，聚光槽10为用左右相对设置的两段横向铺光通道构成的非闭合相对铺光结构，并设置在画相外框9内，画相外框9的正面框檐为上导光檐。从正面看，能通过左右两侧的横向铺光通道以及画相外框9上下两边的框檐围成的矩形视窗看到底板7。因为上下两端开口结构的聚光槽10(即非闭合相对铺光结构)被画相外框9把上下两端的开口遮挡住(实际上聚光槽10是上下开口结构)，而矩形视窗的上下两端外围并没有设置投光件以及横向铺光通道。这种开口结构的聚光槽能实现特殊的铺光效果。
进一步的，图8所示的结构中，可以把左右相对设置的两段横向铺光通道构成的非闭合相对铺光结构改为由一段铺光方向向内的所述横向铺光通道构成的非闭合单段铺光结构，即把矩形视窗的一条边或者相邻的两条边或者三条边用铺光方向向内的所述横向铺光通道实施代替，从而实现单边投光结构的聚光槽或双边投光结构的聚光槽或者三边投光结构的聚光槽，以展示特殊的铺光效果。
其他实施例
可以根据以上实施例中的具体特征进行变化和组合，构成其他形式和结构 特征并满足本发明技术特征的其他实施例。
