• intros：{"brand_intro":"雷士（NVC）成立于1998年，中国本土照明领军品牌，以\"光环境专家\"为定位，产品覆盖商业、工业及家居照明。雷士在工业照明领域拥有完整的供应链体系，其卤素机床灯主打高性价比和本土化设计。创始人吴长江以\"让中国制造照亮世界\"为愿景，强调品控中的\"零缺陷\"理念——每盏灯出厂前需经过72小时老化测试。雷士在中国拥有超过3000家专卖店，市场份额在国产机床灯品牌中排名第一。","product_intro":"雷士卤素机床灯以\"加长臂\"为差异化卖点，臂展达80cm，适合大型机床或需要远距离照明的场景。核心卖点：灯头采用防爆玻璃罩，耐冲击且防油污；内置散热风扇，主动降低灯体温度；底座为重型铸铁材质，稳定性极佳。与进口品牌相比，雷士价格仅为欧司朗的60%，但显色指数（CRI≥85）稍低，更适合对色彩要求不高的粗加工、焊接或仓库照明。灯管寿命约1200小时，更换成本仅25元/支。","key_specs":{"功率":"55W","色温":"2800K（暖黄光）","显色指数":"CRI≥85","灯臂长度":"80cm（可折叠）","散热方式":"主动风扇散热","底座重量":"3.5kg（铸铁）"}}
