Description

一种护眼LED光源
技术领域
本发明涉及LED制造领域,特别涉及一种护眼LED光源。
背景技术
由于LED技术的迅猛发展,新型的LED照明光源以其节能、环保、耐用等特点越来越被人们所使用,正逐渐取代常规照明光源。但同时,LED光源对视网膜的危害以及对生物日常生活节律的影响也在提示我们要清醒地看到LED照明对人体生物安全方面的风险。
现有的技术方案一:采用高能量蓝光芯片激发荧光粉,将CRI数值做高,实际照射时颜色还原度高,但是其为了提升颜色还原逼真度和光效,使用的高能量蓝光比例较大,而高能量蓝光对人眼伤害最大;技术方案二:使用紫光芯片激发RGB荧光粉,蓝光相对较少,经过适当调整,CRI值较高,引入了紫外线光谱,同时,高能量蓝光比例相对较高,同时成本很高,市场使用率较低;技术方案三:采用的是OLED电流注入型发光显示器,在外加电压的驱动下,空穴和电子分别从正极和负极注入到有机材料中,空穴与电子在有机层中相遇、复合,释放出能量,将能量传递给有机发光物质的分子,使其从基态跃迁到激发态,激发态很不稳定,受激分子从激发态回到基态,辐射跃迁而产生发光现象,此光源光效低、容易破碎,生产时控制比较困难,并且由于尺寸比较大,使用较大功率照明时,结构受到很大限制,不良率非常高,成本昂贵,寿命短。
发明内容
为了克服现有技术的上述缺陷,本发明提供一种护眼LED光源,将高能量蓝光比例做到最低,而有益的蓝光比例基本不改变,同时将CRI值调整到90以上,使物体显色更真实,照射物体还原更逼真,眼睛更舒适。
本发明解决现有技术中的问题所采用的技术方案为:一种护眼LED光源,包括LED支架、碗杯、点胶区,所述碗杯设置在LED支架上,碗杯内设置有点胶区,该点胶区上设有固晶区,所述固晶区设置有LED芯片,所述点胶区上还覆盖有荧光胶,该荧光胶完全包裹着LED芯片,所述LED支架的正负极通过金线连接,其特征在于:所述荧光胶由荧光粉和硅胶组成,该荧光粉和硅胶的比例为1:4,所述荧光粉为530nm绿粉、585nm黄粉、630nm红粉和670nm红粉按质量比为(14-18):(0.5-1.5):(2-4):(1-3)的混合物。
作为本发明的优选方案,所述固晶区的金属片为高导热红铜支架,LED芯片固定在金属表面。
作为本发明的优选方案,所述LED芯片的波长范围为455nm-460nm的蓝光,型号为三安 1734芯片。
作为本发明的优选方案,所述碗杯采用高导热PCT材质,碗杯的杯体可固定胶水成型。
与现有技术相比,本发明具有以下技术效果:
本发明通过所调试的一定比例荧光粉配比,将高能量蓝光比例做到最低,而有益光比例基本不变,同时调整各色粉和LED芯片的波长,将CRI值调整到90以上,使物体显色更真实,照射物体还原更逼真,眼睛更舒适。
