Description

基于多通道LED的对色灯箱 技术领域
本发明属于LED照明领域，特别涉及基于多通道LED的对色灯箱。
背景技术
标准对色灯箱广泛应用在纺织品、印染、印刷、塑胶、颜料、油漆、油墨、摄影等颜色领域，对一些要求高的商品，特别是出口产品，品牌商对颜色的一致性要求非常高，有一项重要的指标就是要在符合国际标准的对色灯箱下检查物品的颜色偏差，如生产样品与目标样品的色差。
对色灯箱通常提供多种光源，如模拟国际照明委员会标准日光D50或D65的光源，商店展示厅灯光的TL84、CWF、U30，水平日光HORIZON、紫外灯管UV等。传统的对色灯箱通常采用普通的荧光灯作为照明光源，在使用超过2000小时之后，光源亮度就会明显降低，就需要更换灯管；荧光灯管组成的灯箱可实现的光谱功率分布固定，如若需要其他光谱分布，则需要增加灯箱的荧光灯管，十分不便；此外，荧光灯在使用时需要较长的预热时间。
LED光源具有发光效率高、耗电量少、使用寿命长、安全可靠性强、无频闪和有利于环保等诸多优点，因此采用LED光源替代对色灯箱中的荧光灯光源是大势所趋。由于LED光源的光谱窄带性和多样性，因此通过多种不同出射波长的LED灯珠发光混光达到光谱功率分布的可调，从而实现高质量复现标准日光D50、D65和其他光源。将LED技术应用于传统的对色灯箱，将大大提高灯箱的使用寿命，缩短灯箱照明所需的预热时间。
