Description

一种自散热路灯
技术领域
本发明属于路灯照明设备技术领域，具体涉及一种自散热路灯。
背景技术
随着照明技术的不断发展，传统的白炽灯泡因其能耗大，发光效率低而逐渐被淘汰，而现有使用较多的荧光灯泡虽然发光效率较高，但实际使用寿命较短。因此发光效率高、能耗低且使用寿命极长的LED灯泡逐渐成为了现有灯泡中最受欢迎的种类。不过由于LED灯泡的发光体体积较小，散热面积有限，因此其在使用过程中的温度很高，常常会对其周边电路造成一定的影响，因此为了解决LED灯泡的散热问题，就需要对其结构进行改进。
发明内容
为实现上述目的，本发明提供如下技术方案：
一种自散热路灯，包括灯柱，灯柱侧面开有多个孔洞；灯柱上端安装有灯罩；灯罩内部安装有LED灯泡；LED灯泡下方安装有散热格栅；散热格栅下方安装有风扇。
所述风扇为轴承静音风扇。
所述散热鳍片为铝制散热鳍片。
本发明的有益效果是：该自散热路灯采用了散热鳍片与风扇结合的散热系统，对LED灯泡的发光片底部进行不断鼓风，起到散热作用，同时灯柱上开有多个孔洞，使灯柱内部与外部空气更加流通，提升散热效果。
附图说明
为了更清楚的说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要的使用的附图进行简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来说，在不付出创造性劳动的前提下，还可以通过这些附图获得其他的附图。
图1为本发明的结构示意图；
图中：1-LED灯泡：2-灯罩；3-散热鳍片；4-风扇；5-孔洞；6-灯柱。
具体实施方式
下面详细描述本发明的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本发明的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
实施例：
如图1，一种自散热路灯，包括灯柱6，灯柱6侧面开有多个孔洞5；灯柱6上端安装有灯罩2；灯罩2内部安装有LED灯泡1；LED灯泡1下方安装有散热格栅3；散热格栅3下方安装有风扇4。
具体的，所述风扇1为轴承静音风扇，工作时噪音小，能耗低，减少对周边环境的影响。所述散热鳍片3为铝制散热鳍片，密度低导热性好，成本低，降低设备的生产成本，提升散热效果。
本发明中的自散热路灯采用了散热鳍片与风扇结合的散热系统，对LED灯泡的发光片底部进行不断鼓风，起到散热作用，同时灯柱上开有多个孔洞，使灯柱内部与外部空气更加流通，提升散热效果。在路灯作为绿地景观路灯时，在温度较低的季节可以通过孔洞鼓出灯体内部的热空气，对周围环境起到一定的保温作用。
在本说明书的描述中，参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
