Abstract

Take the perspective of cool hue and warm hue, this paper investigated atmosphere perception of LED dynamic colored lighting, as well as physical parameters effects. An experiment was carried out in a LED lighting lab with 8 fully functioned LED cubes, which can produce temporal color-varied lighting. 30 Chinese observers (14 males, 16 females, mean age=25.43, SD= 2.86) evaluated 36 Light conditions (2 lightness levels × 2 chroma levels × 3 hue range types × 3 speed) with 25 word pairs questionnaire. 4 atmosphere dimensions were extracted as coziness, soberness, liveliness and warmness. High speed and high chroma is helpful to create liveliness; low speed and low chroma is more cozy. Warm hue range makes intimate and warm space; cool hue range usually increase soberness. Differences caused by gender and design background were also found.
LED动态照明的氛围感与色彩的冷暖色调变化
本文从冷色调和暖色调的角度,研究了LED动态彩色照明的氛围感受,以及物理参数的影响。在LED照明实验室中,用8个功能齐全的LED立方体进行了实验,这些立方体可以产生瞬时变色照明。30名中国观察员(男14名,女16名,平均年龄25.43岁,SD= 2.86)采用25词对问卷对36种光照条件(2种亮度水平× 2种色度水平× 3种色调范围类型× 3种速度)进行评价。提炼出舒适、清醒、活泼、温暖4个大气维度。高速和高色度有助于创造活泼;低速低色度更舒适。暖色调范围使空间亲切温馨;冷色系通常会增加清醒度。性别和设计背景造成的差异也被发现。
