本文以中国古代豆形灯为例,分别从席地而坐、席地而坐向垂足而坐转化及垂足而坐这三个不同时期,来探讨人们坐姿方式的改变对古代灯具的影响,从而得出伴随人们坐姿方式由原先的席地而坐转化为垂足而坐及家具高度的提高,豆形灯的高度呈现降低趋势,形式也变得更为灵巧,纹饰部位也随之降低。这种设计上的变化充分体现了古代灯具设计中的和谐设计观念。 Taking the ancient Chinese bean-shaped lamp as an example, this paper discusses the influence of the change of sitting posture on the ancient lamp from sitting and sitting on the ground, taking the place of sitting on the foot and sitting on the foot and sitting on it.
