为使本申请的目的、技术方案和优点更加清楚,下面将结合本申请具体 实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然,所描述的实施例仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
以下结合附图,详细说明本申请各实施例提供的技术方案。
本申请实施例提供一种LED散热装置,如图1所示,LED散热装置具备散热侧1、集热侧2和连接耳部3,其中集热侧2用于贴合LED光源并将LED光源发出的热量传递至与集热侧2相对的散热侧1以提高散热效率,为便于描述各部件之间的位置关系,将集热侧2指向散热侧1的方向为第一方向a。
本申请实施例所述的LED散热装置,通常的使用环境是集热侧2朝下,散热侧1朝上,通过连接耳部3安装在框架或其他载体上,即适用于出光方向朝下的使用环境,当然也可以根据需要将出光方向安装为朝向其他方向。
如图1及图3所示,槽底102具备沿第一方向a凸起的凸出部1026,凸出部1026可以如图1所示连接V字形的顶端,也可以设置为槽底102的一条边缘,如图3所示,槽底102自凸出部1026向第一方向a的反方向逐渐平滑延伸,这样当槽内存在积水时,由于存在***的凸出部1026,可以自槽中沿排水孔1028或侧端口108流出,同时由于凸出部1026的存在,使得槽底102相当于拥有一根贯穿槽底的加强筋,增加了对扭转力的抗性。
本申请采用在LED散热装置上的散热槽的槽底设置凸出部,并使槽底自凸出部逐渐降低,形成一个平滑的排水通道,可以通过如排水孔或侧壁等结构将积水排出,同时可以清除槽底的污物,实现了自动排水排污的技术效果。
如图1所示,散热侧1具备散热槽10,本申请所述的散热槽10如图1所示,为散热侧1向第一方向a的反方向凹陷形成的一个凹槽,散热槽10具备槽口100、槽底102和散热鳍片结构104,槽口100与槽底102相对,槽口100可以如图1所示与槽底102形状相同,也可以设置为不同,散热鳍片结构104自槽底102凸起,散热鳍片结构104可以是如图1所示的阵列排布, 也可以不具备一定的排列顺序而散乱排布,只要在第一方向a上不超过槽口100即可,这样,槽口100可以为散热鳍片结构104提供一定的阻挡作用。
为进一步增加散热鳍片结构104受保护的程度,散热侧1还具备散热侧外缘12,连接耳部3自散热侧外缘12向背离槽口100的方向延伸,连接耳部3可以如图1所示设置为两个且相对于散热槽对称设置,也可以设置为多个并沿槽口100的周向均匀排布等。连接耳部3上设置有用于与外部连接的连接件30,连接件30可以是如图1所示的连接孔,也可以是挂钩等其他结构,槽口100在第一方向a上不超过连接耳部3,可以是连接耳部3超过槽口100,也可以是两者如图1所示相互平齐。通过如上设置,可以有效的降低散热鳍片结构104直接受压而损坏的概率,从而保证散热效率。
为增强连接耳部3的机械强度,在本实施例中,连接耳部3具备朝向方向为第一方向a的承压面32和背离承压面32的加强面34,如图1所示,承压面32与散热侧1相互平齐,也可以设置为承压面32在第一方向a上超过散热侧1,加强面34上设置有凸出的加强筋340,通过使用加强筋340增加了连接耳部3的机械强度。在本实施例中,如图1所示,还具备散热装置侧面4,集热侧2通过散热装置侧面4与散热侧1相连,连接耳部3与散热装置侧面4相临接,加强筋340可以如图1所示,自散热装置侧面4延伸并贯穿加强面34,这样加强筋340的一端可以被固定,加强作用更好。
为增加散热效果,在本实施例中,散热鳍片结构104自槽底102沿第一方向a延伸,并延伸至槽底102,这样可以在散热鳍片结构104之间形成相对通畅的空气流动通道,并将散热鳍片结构104的表面积增加至最大。
为增加散热鳍片结构104本身的机械强度,在本实施例中,散热鳍片结构104包括第一鳍片组1040和第二鳍片组1042,槽底102具备槽底中心1020,第一鳍片组1040和第二鳍片组1042相对于槽底中心1020对称排布,如图1所示,在散热槽10内可以设置多个对称排布的第一鳍片组1040和第二鳍片组1042,这样可以形成较为均匀的受力结构,增加机械强度。为进一步增加 散热鳍片结构104的机械强度,第一鳍片组1040和第二鳍片组1042在垂直于第一方向a上的截面形状可以如图1所示设置为V字形,V字形的顶端指向槽底中心1020,这样在V字形的顶端形成筋位,增加机械强度。
在LED散热装置使用过程中,不仅会受到外界的压力,还有可能受到扭转力,为增强本申请实施例所述的LED散热装置对扭转力的抗性,如图1所示,槽底102包括第一散热面1022和第二散热面1024,第一散热面1022与第二散热面1024相临接并形成自槽底102沿第一方向a凸起的凸出部1026,凸出部1026连接V字形的顶端,进一步增加了对扭转力的抗性。
如图1所示,为增加散热效率,本申请实施例所述的散热槽10为U形槽,U形槽具备相对的侧壁106,相对的侧壁106与槽底102形成了一对相对的侧端口108,散热鳍片结构104贯穿两个侧端口108,这样空气可以从一个侧端口108流入,经过散热鳍片结构并从另一个侧端口108流出,提升了散热效率。
为提升排水性能,槽底102开设有贯穿散热侧1与集热侧2的排水孔1028,这样当散热侧1朝上设置时,可以有效排出其中的雨水等积水。同时集热侧2开设有贯穿散热侧1与集热侧2的电源通孔20,电源通孔20用于穿过给LED供电的LED电源线,在电源通孔20内设置有通孔防水结构5,通孔防水结构5可以是橡胶制成,也可以是发泡胶制成,能够填充LED电源线与电源通孔20之间的间隔并阻止水分穿过电源通孔20即可。为保证LED散热装置整体机械强度,电源通孔20在散热侧1的开口200位于槽底中心1020,电源通孔20沿第一方向a延伸。
本申请实施例还提供一种使用上述LED散热装置的灯具6,如图4及图5所示,该灯具6具备灯体60,图4、图5、图6所示的灯体60设计为适用于路灯的灯具造型,也可以设计为适用于其他用途的灯具造型,灯体60上开设有贯通的安装腔62,如图5所示,安装腔62具备相互背离的第一开口64和第二开口66,以方便安装内部结构和出光。
如图4所示,当设计为路灯时,图4所示的为灯具6的朝上一侧,LED散热装置并排安装在安装腔62内,散热侧1朝上,从而使固定LED光源68的集热侧朝下,根据上述的LED散热装置结构,此时朝上的散热侧1可以有效排出其中的积水和污物。
图6所示的为灯具6的第二开口66一侧,多个LED光源68固定于集热侧2上,在设置为路灯时可以向下出光。
本申请采用在LED散热装置上的散热槽的槽底设置凸出部,并使槽底自凸出部逐渐降低,形成一个平滑的排水通道,可以通过如排水孔或侧壁等结构将积水排出,同时可以清除槽底的污物,实现了自动排水排污的技术效果。
本申请上文实施例中重点描述的是各个实施例之间的不同,各个实施例之间不同的优化特征只要不矛盾,均可以组合形成更优的实施例,考虑到行文简洁,在此则不再赘述。
以上所述仅为本申请的实施例而已,并不用于限制本申请。对于本领域技术人员来说,本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等,均应包含在本申请的权利要求范围之内。
