摘要
有色宝石种类繁多,由于所含化学物质的不同,其颜色往往具有多样性、渐变性和不规则性。使用市场上常见的普通珠宝展柜灯进行照射时,由于灯具光谱的不连续性,较难还原有色宝石在日光下的夺目光彩。本实验选用了12种单色光LED芯片制作了一款LED全光谱组装灯,更好地复现多彩宝石在阳光的下的本来面貌。通过实测反射光谱以及肉眼主观评价的方式,将LED组装灯与普通珠宝展柜灯进行了对比,我们发现,自制的全光谱珠宝灯具有更好的珠宝展示表现力,也更受消费者欢迎。
There are many kinds of colored gemstones. Because of the different chemical substances, their colors are often diverse, gradual and irregular. Under the traditional LED lamps, due to the discontinuity of the spectrum, the color of the jewelry is difficult to be restored to the shining brilliance under the sun. In this experiment, 12 kinds of LED chips were selected to fit the solar spectrum, and colorful gems were reproduced in the sunlight. From reflectance spectrum test and subjective naked eye observation, we’ve discovered that in between LED assembly lamp and traditional LED lamp, the solar spectrum lamps presents jewelry better and much more popular among consumers.
