在另一个实施方式中，多个LED灯可以呈大面积点阵式排布，大面积点阵式LED灯可以设置在导光件14后侧，可以直接依靠导光件14导光，以实现面发光。
在某些实施方式中，发光件12采用COB(Chip On Board，COB)灯，COB灯可以理解为集成封装的LED灯，COB灯的制作工艺可以是在LED芯片直接贴在高反光率的镜面金属基板上的。COB灯形成的光源可以简单理解为高功率集成面光源，COB灯电性稳定、散热设计科学合理、能够形成均匀且清晰的光束。如此，能够使得导光件14产生明亮且均匀的面光源以照亮微波炉内部。
在某些实施方式中，发光件12还可以包括卤素灯、白炽灯、白光LED、RGB灯珠、UV-LED 等，此处不作限定。值得一提的是，RGB灯珠是能够发出红(R)、绿(G)、蓝(B)等彩色光线的灯珠。RGB灯珠产生的光线可以充当氛围灯，提升用户的使用感受。家用电器100可以在不同的功能的情况下，发光组12能够发出不同颜色的光线。

UV-LED也被称为紫外发光二极管，UV-LED的光线能够将能量高度集中在紫外光谱段，通过UV-LED产生的光线可以实现对腔体20内部、餐具或者食物进行杀菌消毒，也即是说，UV-LED具有杀菌消毒的功能，使用UV-LED作为发光件12的情况下，通过导光件14产生的面光源具有杀菌消毒的作用，能够实现消毒杀菌无死角。
导光件14包括导光板，导光件14呈薄板状，导光件14设置在腔体20的内部。在某些实施方式中，导光件14的大小、形状、面积和厚度均与腔体20内部的空间容量相关。在一个例子中，腔体20内部的空间为：40厘米宽、50厘米高和55厘米长的空间容量。若导光件14设置在家用电器100内部的宽与高的对应连接的一侧的情况下，导光件14的长可以小于或等于40厘米，导光件14的高可以小于或等于50厘米(导光件14的长与家用电器100内部的宽对应设置，导光件14的高与腔体20内部的高对应设置)。导光件14的宽(厚度)可以为3毫米、5毫米、7毫米、1厘米、2厘米等，此处不作限定。

在一个实施方式中，家用电器100包括微波炉，微波炉包括腔体20，微波炉能够使用磁控管或固态源产生微波信号，再通过天线将微波信号馈入至腔体20内以加热食物。可以将导光件14设置在腔体20内以实现对整个腔体内的照明，发光件12设置在腔体20外可以延长发光件12的使用寿命，避免高温等原因对发光件12造成损坏。值得一提的是，天线也可以替换为电缆、波导等，用于将微波信号馈入到腔体20中。
请一并参阅图3和图4，腔体20开设有导光孔22，在发光件12处于发光的情况下，光可以通 过导光孔22照射到导光件14上，使得导光件14将发光件12发射的光源转换成面光源。值得一提的是，发光件12与导光件14相对设置。腔体20包括多个内壁，内壁包括内侧面和外侧面，内侧面靠近腔体20内部的空间，外侧面与内侧面相背。发光件12可以设置在其中一个内壁的外侧面，导光件14可以设置在同一个内壁的内侧面，如此发光件12与导光件14相对设置。

在某些实施方式中，导光孔22的上方、下方均可以设置导光结构，导光结构具有微波屏蔽功能，如此导光结构既能够将发光件12产生的光通过导光孔22和导光结构传递至导光件14上，也能够避免导光孔22处产生微波泄露。
在某些实施方式中，导光孔22的最大宽度小于或等于8毫米。
在某些实施方式中，对于特定的家用电器100，例如微波炉，导光孔22的最大宽度应小于或等于8毫米。对于微波炉来说，导光孔22若开设过大，则会造成微波泄露。导光孔22的最大宽度小于或等于8毫米既能够光的传播，也能够避免较大的微波泄露。

如此，导光件14可以通过丝印、镭雕、凹点、凸点、磨砂、条纹等结构进行光的折射、反射，利用光的折射和反射等原理，能够将导光件14周边的线光源转换成面光源。面光源能够避免腔体20内器具或食物阻挡无法观察到整个腔体20的情况，同时面光源光照均匀不刺眼，照明效果好，实用性强。
值得一提的是，丝印、镭雕、凹点、凸点、磨砂、条纹等结构可以是在导光件14上一体形成 的，例如通过腐蚀、雕刻、粘贴、高温压制等方式形成的，此处不做限定。在某些实施方式中，导光件14可以采用镭雕技术，镭雕技术具有呈现效果好和实用价值高等优点。

在又一个实施方式中，导光件14的材质为复合材质。例如：导光件14由玻璃-塑料-玻璃构成，两侧玻璃可以与中间的塑料粘合连接，也可以在两侧玻璃中间真空设置塑料。如此有利于家用电器100的密闭性。
在又一个实施方式中，导光件14包括异形玻璃，玻璃上包括多个反射结构，如此可以利用反射结构均匀地进行导光，异形玻璃可以是一体形成的，此处不作限定。
在某些实施方式中，家用电器100还包括散热组件，散热组件可以包括散热风机和散热孔。散热风机和散热孔可以对发光组件10进行散热，避免发光组件10在使用时温度过高，也可以避免发光组件10用于高温的家用电器100(例如烤箱)导致温度过高难以散热。散热风机可以是轴流风扇，也可以是涡流风扇。散热风机的数量是可以是单个，两个或多于两个，对应于散热风机的位置开设有散热孔，以使得散热风机排出的气流能够流出家用电器100。
在本说明书的描述中，参考术语“一个实施方式”、“一些实施方式”、“示意性实施方式”、“示例”、“具体示例”或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施方式进行变化、修改、替换和变型。
