Description
散热灯体及其构成的LED灯
技术领域:
本实用新型涉及铝合金型材和铝合金压铸件以及LED照明技术领域。
背景技术:
LED照明是一种很有发展前景的节能照明技术。现已有不少厂家推 出了各种各样款式的LED灯。半导体LED的发光特点之一是单向平面发 光,即出光角度小于18(T ,同白炽灯泡和荧光节能灯的全方位出光特点 比较,在某些情况下是一种优点,例如用于台灯、路灯和某种局部照明, 光的指向性好,光能利用率更高、更节能。但用于泛光照明的场合下,照 明效果就差强人意,例如用于住房厅室的泛光照明以及用于商店内的照 明,由于LED灯的光线集中向下照射,侧向照射光很弱,向上发射的光更 是没有,造成四面墙壁光照不足,天花板顶棚更是昏暗。人们曾经习惯了 白炽灯泡和荧光灯的光照环境,进入这样的LED光照环境后会产生一种 压抑感。 发明目的:
本实用新型的目的是要设计一种侧向出光被加强的LED灯,并且同 时要较好地解决LED的散热问题,设计出一种能实现上述目的的散热灯 体。
发明内容:
本实用新型的技术解决方案是:散热灯体采用铝合金材料由挤压工艺 或压铸工艺制成,灯体的一端设计有散热翅片,另一端设计成多边形棱柱
3体或棱台形状,LED发光元件安装在各侧面和端面,这样就使LED灯的 侧向出光有了加强,侧面和端面的LED功率可以根据实际需要调整设计, 使LED灯的照明效果符合人的视觉要求。
技术效果:
本实用新型LED灯增强了侧向出光强度,使之更适用于泛光照明场 合,最大限度发挥出半导体照明的节能优势。 附图说明-
图1是本实用新型的实施例之一的结构示意图; 图2是图1的横截面视图;
图3是本实用新型的实施例之二的结构示意图; 图4是图3的A—A截面视图; 图5是图3的B向视图。 具体实施方式:
请参见图1和图2,这是实施方案之一的结构示意图。图中示出灯头 1和与灯头连接的塑料壳盒2,其中放置有电源模块,与壳盒连接的是具 有本实用新型特征的散热灯体3,它是采用铝合金材料由挤压工艺制成, 其特征是:该灯体型材的中心部位为一棱柱体或圆柱体4a,与棱柱体各 侧面或圆柱体侧面相连接的是若干条散热翅片8,棱柱体内或圆柱体内可 以是实心体,也可以有圆形管道或多边形管道腔,灯体型材上有一段棱柱 体或棱台4b无散热翅片,通常有两种办法实现之, 一是另加工一段棱柱 体或棱台与灯体中心相连接;二是用机加工方法除去灯体型材上一段长度 的翅片,将这段长度的型材加工成棱柱体或棱台,使得这段无翅片棱柱体 或棱台4b与灯体中心的棱柱体或圆柱体4a为一整体无缝隙连接,后者更 有利于热量的有效传导;采用上述散热灯体3构成的LED灯,其特征将多颗LED发光元件5安装在灯体中心棱柱体或棱台4b的各侧面和端面 上,使LED灯有了侧向出光被加强的特点。图中灯罩7与灯体3连接, 由透明或半透明塑料制成,或玻璃制成。但是当灯的功耗比较大时,例如 灯功率大于7W,则必须相应增大散热表面积,即要增长灯体型材的长度, 这时从LED到灯体型材顶端散热翅片的距离就增大了,散热性能和效果 就变差,LED芯片的结温就会偏高,将縮短LED灯的有效工作寿命。采 用下述的技术措施可以解决这个问题,这就是在散热灯体3中心加工出一 管道腔,管道腔的两端被堵塞密封,并且管道腔中被注入适量的单质液体 或混合液体6。液体的沸点温度与需要控制的芯片结温相适应,例如选择 沸点温度为45X:的液体,当LED产生的热量使管腔中液体温度达到45 'C时,液体将沸腾汽化,蒸汽将热量带到管腔的上部传导给管壁,热量再 经翅片表面散发到环境空气中去,蒸汽放热后凝结成液滴下流,如此循环 不断带走LED部位的热量,使LED部位的温度维持在45'C上下。液体 起到加快热量传递速度的作用,并使整个散热灯体的各处温度趋于均衡, 提高了灯体的散热性能,确保LED灯的长寿命。
图3、图4、图5是实施方案之二的结构示意图。与图1和图2所示 的方案不同的是散热灯体13由铝合金压铸而成,其特征是:散热灯体13 的一端为棱柱体或棱台14,另一端连接有若干散热翅片18,中心部位可 以是实心,也可以有管道腔;当有管道腔时,又可以将管道腔两端堵塞密 封,并且在管道腔中注入适量的单质液体或混合液体6;采用上述散热灯 体13构成的LED灯,其特征是多颗LED发光元件5安置在灯体中心的 棱柱体或棱台14的各侧面和端面上,LED灯的侧向出光被加强。图中灯 头l、塑料壳盒2、透光灯罩7与方案之一功能相同,详细说明不作重复。
