• intros：{"brand_intro":"乐凯（Lucky）是中国感光材料行业巨头，前身是保定电影胶片厂，成立于1958年。乐凯曾与柯达、富士并称世界三大胶片巨头，在相纸、胶卷领域拥有深厚技术积累。进入数码时代后，乐凯转型特种感光材料与暗房配件研发，其安全灯产品继承了胶片时代的色彩科学经验，主打低功耗、高显色性。品牌以\"安全、环保、精准\"为品控理念，所有LED灯珠均通过RoHS认证，无紫外辐射。","product_intro":"乐凯LK-LED5R是一款采用LED光源的暗房安全灯，功率仅5W但亮度相当于15W白炽灯。核心卖点是其窄波段红光LED（波长620-630nm），能完美避开黑白相纸的感光区间，同时比传统白炽灯节能70%，发热量极低。产品自带磁吸底座和1.5米USB供电线，可灵活吸附在金属暗房架或墙壁上。相比海鸥的灯泡方案，乐凯LED灯寿命长达50000小时，几乎免维护。适合追求现代暗房效率的进阶用户。","key_specs":{"光源类型":"窄波段红光LED，波长620-630nm","功率":"5W（等效15W白炽灯亮度）","寿命":"50000小时，免更换灯泡","供电方式":"USB 5V/1A，可接充电宝或插座","安装方式":"磁吸底座 + 可旋转支架","适用相纸":"黑白相纸（ISO 100-800）"}}
