路明白光LED新荧光材料打破国际专利壁垒

Source: 阿拉丁照明网 Views: 8174

  昨日,记者从大连市科技局获悉,大连路明集团“硅酸盐荧光粉”系列专利已成功在美国、欧洲和中国台湾获得授权。该系列专利的授权将使我国LED灯用荧光粉的生产突破国际专利封锁和垄断,大大降低白光LED的生产成本,提高我国半导体照明产业的国际竞争力。


  据了解,自白光LED问世以来,国际上一直使用两种不同的荧光材料体系,其专利权分别掌握在日本和德国企业手中,我国企业不但要购买荧光材料,还要向专利所有者交纳专利使用费,并将利润的10%分给专利所有者。这样,产品的生产成本将增加70%左右。而作为世界上LED封箱第一大国,我国有4000多家封箱企业,产品主要以出口为主,产品走向国际市场时,经常因为专利壁垒受到重重阻碍,整个行业一直处于受制于人的境地。


  大连路明集团从2003年开始进行技术研发,在原有技术基础上研制出了“硅酸盐荧光粉”系列。在性能稳定和使用寿命上毫不逊色于现有的两大垄断材料,而且这种材料不仅能使LED发出白光,还能使其发出其他各种颜色的光,这是目前其他材料做不到的。


  据悉,为了推广这一新材料,路明对国内企业不收任何专利费,为国内企业省下了向国外交纳的巨额专利费。
