本发明涉及一种发光散热结构及其发光散热方法,特别是指一种针对LED光源的发光散热结构及其发光散热方法。
背景技术
众所周知,为了有效运转,传统的LED光源需要有效的散热装置来散热,PCT国际申请号为PCT/CN2011/000756中公开了一种LED光源及其制造方法的技术,其记载了一种LED元件,其能通过两侧面发光,从而避免热量聚集在结传统LED光源的结合面和基片上,其LED元件与两荧光元件以三明治的方式直接连接,从而形成一个或多个通道口以藉此达到通过该通道口导引LED元件的热传递。
其结构主要包括一个或多个LED光源组,其中每所述LED光源组包括:至少一LED元件,其中所述LED元件具有一第一发光面和在反面的一第二发光面,其中所述LED元件适于在每所述第一发光面和所述第二发光面通过电致发光提供大于180°角度的照明;两荧光元件,所述两荧光元件分别位于所述LED元件的所述第一发光面和所述第二发光面上部以保持所述LED元件就位,从而使所述LED产生的照明分别从所述发光面出发经过所述两荧光元件;和一电子元件,所述电子元件与所述LED元件藕接以将所述LED元件电连接于一电源。
所述LED元件被所述两荧光元件以三明治方式夹在中间从而保持所述LED元件就位,以使所述第一发光面和所述第二发光面直接压向所述荧光元件上以得到支撑并导引热传递离开所述LED元件,并且所述LED元件被保持在所述荧光元件之间空隙的一LED容纳腔内。
上述的技术应用到具体产品上其产品具有体积小发光效果好,能够利用一个LED光源同时向各个方向同时发光,但是在具体实施的时候,由于其只是通过第一发光面和第二发光面对LED元件进行散热,其思路虽然较好,但是在具体实施的时候存在散热效果不理想,热量散发较慢而引发LED元件过热的情况,更严重的情况下会烧毁整个LED光源,而此是为传统技术的主要缺点。

  11. 如权利要求5所述的一种LED光源发光散热结构,其特征在于:该LED光源为一LED灯具的光源,该LED灯具包括灯座以及灯罩,其中,该灯罩连接在该灯座上,该透明散热板为环状,该散热架连接在该灯座中,该LED双面发光芯片环设在该透明散热板四周,该LED双面发光芯片上包裹有硅胶层,在该灯罩中灌充有导热气体,通过该导热气体能够提升该LED双面发光芯片的散热效率。
  12. 如权利要求1或11所述的一种LED光源发光散热结构,其特征在于:该满附部分包括若干导电散热部分,若干该导电散热部分彼此独立设置,若干该导电散热部分同时附着在该透明散热基板的外表面上,该发光体设置在任意相邻的两个该导电散热部分之间,相邻的该发光体的电连接线分别与该导电散热部分电连接,从而使若干该发光体形成串联并连接关系。
  13. 如权利要求1所述的一种LED光源发光散热结构,其特征在于:该散热导电薄膜层还与外接散热部分相连接,通过该外接散热部分进一步辅助该散热导电薄膜层散热。
