Description

一种白光LED用的透明陶瓷
技术领域
本发明涉及一种白光LED陶瓷材料,尤其涉及一种具有透明功能的白光LED用的透明陶瓷。
背景技术
白光LED自问世以来,便因其使用寿命长、高效节能、绿色环保等优点被誉为继白炽灯、荧光灯、气体放电之后的***照明光源,被广泛用于LCD、手机、数码相机等领域。近年来,随着以白光LED为主的半导体照明产业的飞速发展,白光LED在固态照明方面显示出了巨大的市场潜力和应用前景,引起了各界的高度重视,纷纷设立专利的机构来推动半导体照明技术的发展。
目前的白光LED是利用蓝光LED激发黄色荧光粉涂覆层发出黄色,进而蓝色与黄光复合后发出白光。这种白光LED具有寿命长、绿色环保等特点,蕴含巨大市场潜力和应用前景。
但是现有技术的LED用的陶瓷的传热性差,稳定性差,导致白光LED的寿命短,影响了产品的稳定性。
发明内容
本发明是为了要克服现有技术的缺陷,目的在于提供一种白光LED用的透明陶瓷,该白光LED用的透明陶瓷具有导热效率高,化学稳定性好,寿命长,稳定性好等特点。
本发明解决其技术问题所采用的技术方案是:一种白光LED用的透明陶瓷,由以下份数的组分煅烧组成:70-80份莫来石粉,80-100份钛白粉,50-75份石英粉,100-120份活性高岭土,15-20份二氧化锆 ,8-10份氧化镱,5-8份氧化镧,5-7份硅酸钠,6-10份纳米氧化钬,5-8份氧化镝,8-10份碳酸钙。
进一步的,由以下份数的组分煅烧组成:70份莫来石粉,80份钛白粉,50份石英粉,100份活性高岭土,15份二氧化锆 ,8份氧化镱,5份氧化镧,5份硅酸钠,6份纳米氧化钬,5份氧化镝,8份碳酸钙。
或者是,由以下份数的组分煅烧组成:80份莫来石粉,100份钛白粉,75份石英粉,100-120份活性高岭土,15-20份二氧化锆 ,8-10份氧化镱,8份氧化镧,5-7份硅酸钠,6-10份纳米氧化钬,5-8份氧化镝,8-10份碳酸钙。
综上所述,本发明的白光LED用的透明陶瓷具有导热效率高,化学稳定性好,寿命长,稳定性好等特点。
