近两年,受全球经济低迷和地缘政治冲突影响,全球LED照明市场增速明显放缓、/p>
作为LED照明产业链的中游环节,近两年LED封装的增速也有所放缓。据LED研究院(GGII)统计,2020年中国LED白光封装产值约665.5亿元,同比下?.3%:/p>
2021年,在通用照明出口、显示市场回暖、Mini背光渗透率快速提升等因素推动下,LED行业整体将复苏、/p>
LED研究院(GGII)的数据也显示,2021年中国LED白光封装产值将达到?95亿元,同比增?.4%、/p>
近日,LED产业链相关企业发布了2021年年报。高工LED编制?1家LED封装上市公司业绩报告。结果是什么?
报告称,在下游市场需求旺盛的带动下,上述11家LED封装上市公司整体营收水平总体保持平稳增长,仅联创光电营收出现下滑、/p>
不过,虽然各LED封装厂商营收总体保持增长,但近半数企业营收不增不减,包括万润科技、联创光电、聚飞光电等、/p>
对于净利润的下降,各公司给出的原因主要集中在以下几个方面:资产减值准备、经营成本增加、经济下行等、/p>
由于各公司主营业务占比不同,高工LED分别汇总了各公司的LED封装业务。结果显示,东山精密、兆驰、木林森、国星光电、宏利智汇、瑞丰光电、万润科技、长方集团等8家企业营收保持稳定增长。创光电、聚飞光电等3家企业下跌、/p>
This is the surest way to move beyond design for design’s sake and give consumers a brand that is both undeniably relevant and incredibly engaging. Sure, it’s also a process by which we’ve been competing with world’s leading brands and won many respectable awards. But awards aren’t our goal. While they provide proof of our creativity, the appreciation of our works and offer credibility that comes from peer recognition, they are ultimately a means to acquiring ever more difficult challenges. And that is ultimately what get’s us up in the morning:the thrill of working with clients to try and tackle increasingly challenging branding problems that then lead to successful businesses for clients. Intrigued? Why not give us a shout today and see how we can transform your brand and your business.
