参图1、图2和图6所示为本发明冰箱制冷间室10的一较佳实施方式。本发明的冰箱制冷间室10包括内胆11和L型面光源组件12。其中，内胆11包括内胆的后壁111、顶壁112、底壁(未标号)及侧壁113，内胆的后壁111、顶壁112、底壁及侧壁113共同限定了储物空间。优选地，该制冷间室10为冷藏间室。
在制冷间室10中还设有抽屉组件20，在抽屉组件20上设有至少一个可沿竖直方向上下移动搁板组件30。其中，抽屉组件20包括抽屉本体22和抽屉盖板21，搁板组件30包括搁板本体31和搁板支架32，在本发明的其他实施方式中，搁板组件30也可以是固定的，在此不做详细赘述。
L型面光源组件12设置在内胆11上，用于对制冷间室10内部的照明。L型面光源组件12包括第一面光源本体121和第二面光源本体122，第一面光源本体121覆盖内胆的后壁111且与内胆的后壁111之间形成有风道40，第二面光源本体122覆盖至少部分的内胆顶壁112。优选地，第一面光源本体121和第二面光源本体122的连接处123弧形过渡。
在本实施方式中，第一面光源本体121的一端与第二面光源本体122弧形连接，另一端延伸至抽屉盖板21的下方，第二面光源本体122远离第一面光源本体121的一端延伸至胆口，即靠近制冷间室10的门体(图未示)，这样的设置的好处在于：用户在打开冰箱门体 时，看到的L型面光源组件12是完全覆盖内胆顶壁112和后壁111的，照明面积大，视觉效果好。
进一步地，结合图3、图4及图5所示，在第一面光源本体121沿竖直方向的至少一侧设有第一饰条13，在本实施方式中，在第一面光源本体121沿竖直方向的两侧均设有第一饰条13，第一饰条13与内胆的侧壁113之间具有间隙(未标号)，该间隙与风道40中的风道盖板41配合形成出风口50。风道40中的风通过出风口50进入制冷间室10内。由于风道盖板41与内胆的侧壁113配合形成一个相对密闭的通道，使得送风更加顺畅。
第一饰条13上还设有开口131，搁板支架32在开口131定义的轨迹内运动以实现搁板组件30沿竖直方向上下移动，使得制冷间室10的存储空间灵活多变。
参图6-7所示，第二面光源本体122与所述内胆的顶壁112之间具有闪缝50，在本发明中，为了遮盖闪缝16，在第二面光源本体122远离第一面光源本体121的一端设有装饰灯15，即装饰灯15靠近制冷间室10的门体(图未示)设置。具体地，在第二面光源本体122远离第一面光源本体121的一端设有第二饰条14，装饰灯15设于第二饰条14上。进一步地，装饰灯15包括光源151和灯罩152，灯罩152将光源151发出的光线导引至内胆的顶壁112以遮盖闪缝50。另外，装饰灯15还起到装饰的作用。
优选地，参图5和图7所示，在第一饰条13上设有与第一面光源本体121适配的第一安装槽132，在第二饰条14上设有与第二面光源本体122适配的第二安装槽141，第一饰条13通过第一安装槽132与第一面光源本体121相互卡合固定，第二饰条14通过第二安装槽141与第二面光源本体122相互卡合固定。
L型面光源组件12还包括分别设置在第一面光源本体121中的第一LED灯条(图未示)和设置在第二面光源本体122中的第二LED灯条(图未示)。优选地，第一LED灯条设置在第一面光源本体121远离第二面光源本体122的一端，第二LED灯条设置在第二面光源本体122远离第一面光源本体121的一端。两个LED灯条发出的光分别射入第一面光源本体121和第二面光源本体122，点亮第一面光源本体121和第二面光源本体122，增大了制冷间室10内的照亮面积，使得冰箱制冷间室10内部具有良好的照明。其中，只有一个LED灯条发出的光为可调节的彩色光，另一个LED灯条发出的光为单一颜色的白光。第一面光源本体121和第二面光源本体122均包括反射片(图未示)、导光板(图未示)、扩散片(图未示)、菲林片(图未示)等，且均具有铝合金材质的边框结构。
在本发明中，L型面光源组件12可以发出不同颜色灯光以对应制冷间室10内不同的功能指示。设置在第二面光源本体122端部的第二LED灯条发出的光为可调节的彩色光， 其包括能发出红、绿、蓝三种颜色的LED灯及控制红、绿、蓝三种颜色的LED灯的开关及亮度的驱动电路(图未示)，驱动电路采用PWM信号控制红、绿、蓝三种颜色LED灯的开闭，并调节三种颜色灯的亮度并相互混合，从而形成更多的色彩效果，冰箱(图未示)还包括用于感测制冷间室10中温度的温度传感器(图未示)，温度传感器电性连接驱动电路，驱动电路被配置为根据温度传感器反馈的温度信号控制红、绿、蓝三种颜色的LED灯的开关及亮度。而设置在第一面光源本体121端部的第一LED灯条只发单一颜色的白光。第一LED灯条和第二LED灯条发出的光分别从L型面光源组件12的射入并在第一面光源本体121和第二面光源本体122的弧形连接处123交汇，满足照明作用的同时，也实现了多彩光的效果。
具体地，参图8所示，第二LED灯条包括LED红灯、LED绿灯、LED蓝灯及控制三种灯开关和亮度的驱动电路。LED红灯、LED绿灯、LED蓝灯的正极接LED_VDD的驱动电压，负极分别与LED_G、LED_R、LED_B控制信号连接，这三个控制信号分别通过限流电阻R404、R405、R406后分别与MOS管Q401、Q402、Q403电性连接，MOS管作为开关分别由LED_PWM_R、由LED_PWM_G、由LED_PWM_B信号控制，LED_PWM_R、LED_PWM_G、LED_PWM_B信号均与冰箱的温度传感器电性连接。设置在第二面光源本体122端部的LED灯条发光原理为：在二极管驱动电压的作用下，通过改变流过PN结电流强弱来调节发光强度，由图9可知，在LED_PWM_R输入高电平时，MOS管Q401导通，LED_VDD作用在LED红灯上且与GND形成回路，通过合适的限流电阻R404驱动LED红灯发光，当在LED_PWM_R输入低电平时，MOS管Q401截止，LED_VDD作用在LED红灯上但与GND形成断路，LED红灯无电压电流通过，LED红灯熄灭。同理，LED绿灯和LED蓝灯也是分别通过驱动LED_PWM_G和LED_PWM_B的高低电平来控制发光和熄灭的。
当LED_PWM_R输入PWM信号时，MOS管Q401在PWM信号控制下变成高频开关，把作用在LED红灯上的LED_VDD电压转变成高频方波信号，经过滤波电容D604的滤波平滑，实现变压，变压的大小可以通过调节PWM信号的占空比来调节，从而改变流过LED红灯的电流来调节发光强度。同理，LED绿灯和LED蓝灯也是分别通过到输入PWM信号LED_PWM_G和LED_PWM_B上来调节发光强度的。由此，温度传感器感测制冷间室对应位置处的温度，驱动电路根据温度传感器反馈的温度信号控制第二LED灯条的出光效果，从而实现在不同温度下控制LED红灯、LED绿灯、LED蓝灯的开关及其各自的发光强度，L型面光源组件12显示不同的颜色。
相应地，本发明还提供一种冰箱(未图示)，该冰箱通过采用上述各实施方式中介绍的冰箱用制冷间室，可以取得上述各实施方式中冰箱用制冷间室具有的有益效果，并且，由于对该冰箱的其他结构或功能并未做出改进，故在此对该冰箱的其它结构也不再赘述。
