Description

汽车照明灯具及其灯具散热机构
【技术领域】
本发明涉及照明技术，特别是涉及一种灯具散热机构及使用该灯具散热机构的汽车照明灯具。
【背景技术】
汽车灯具，为保证安全行车而安装在汽车上的各种交通灯。汽车灯具可分为用来为驾驶员提供照明的汽车照明灯具及用来提示车辆信息的汽车信号灯两类。
传统的汽车照明灯具一般为以铝基板、铜基板或是铝合金散热器一体的导热结构。汽车照明灯具的灯珠设置于基板上，灯珠产生的热量由基板的正面传递至基板的反面，位于基板的反面的热量再经由导热率较高的导热柱传导至散热结构上进行散热。然而，热量从基板的正面传递至反面的过程中，中间需经过多层结构，所以热量的传导路径较长，其散热效果不好，因此传统的汽车照明灯具普遍具有寿命较短的缺点，需要经常对汽车照明灯具进行养护和更换，提高了用户的使用成本。
【发明内容】
基于此，有必要提供一种散热性能较好的灯具散热结构，还提供了一种使用该灯具散热结构的汽车照明灯具。
一种灯具散热机构，用于对光源产生的热量进行散热，包括：
散热器；
导热片，包括两个相对的侧表面以及连接两个侧表面的侧边，所述一侧边与所述散热器相抵持；及
基板，设置于所述导热片的侧表面上；
其中，所述光源设置于所述基板上，所述光源、所述基板及所述导热片依次层叠，所述光源产生的热量能够通过基板及所述导热片传递至所述散热器。
一种汽车照明灯具，包括：
上述灯具散热机构；及
光源，所述光源设置于所述导热层上。
本发明的一个或多个实施例的细节在下面的附图和描述中提出。本发明的其它特征、目的和优点将从说明书、附图以及权利要求书变得明显。

图2为图1所示汽车照明灯具的结构示意图。
【具体实施方式】
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本发明。本文所使用的术语“及／或”包括一个或多个相关的所列项目的任意的和所有的组合。
请一并参阅图1及图2，一实施例中的灯具散热机构100，用于对光源200进行散热。在本实施例中，灯具散热机构100具体用于汽车照明灯具10。在其他实施例中，散热机构100还可以用于隧道灯或家用照明灯等其他灯具。灯具散热机构100包括散热器110、导热片130及基板150。
导热片130包括两个相对的侧表面以及连接两个侧表面的侧边。导热片130的一侧边与散热器110相接触。基板150设置于导热片130的侧表面上。具体的，基板150为铝基板、铜基板或陶瓷基板。散热器110为铝合金散热器110。基板150与导热片130之间可通过螺纹固定件、铆接件进行固定，也可以通过导热胶进行粘接。
光源200设置于基板150上。光源200具体可包括LED灯珠（图未示）。光源200、基板150及导热片130依次层叠。光源200与基板150，以及基板150与导热片130之间具备较大的散热贴合面积，有助于将光源200产生的热量发散。
具体在本实施例中，导热片130延伸超出基板150，基板150只占据部分导热片130的表面，以使得基板150整个表面均与导热片相贴合，最大化的增加散热面积。
光源200具体可包括多个LED灯珠。多个LED灯珠在基板150上排布。可以理解，在其它实施例中，光源200还可为白炽灯、卤素灯、荧光灯等，其类型不限于上述的LED灯珠。
具体在进行工作时，光源200产生的热量能够通过基板150及导热片130传递至散热器110，以将热量迅速发散出去，降低了灯具的温度，有助于灯具寿命的延长，无须频繁的对其进行保养或更换，进而降低了使用成本。
可以理解，基板150也不限于铝基板或铜基板或陶瓷基板，还可由其它材料制成。散热器110还可为其它材质的散热器，不限于铝合金材料。
具体在本实施例中，导热片130为石墨片130。基板150的数量为两个，两个基板150分别贴合于导热片130的两个相对的侧表面上。光源200的数量也可为两个，两个光源200分别设置于两个基板150上，且两个光源200均位于基板150的外侧的侧表面上。
石墨的导热系数高达1500W/(m•K)，因此，导热片130为石墨片130，可以加大导热片130的散热效率，更好的进行散热。需要指出的是，上述导热片130还可为导热硅胶垫、相变导热材料片、纳米碳铜箔或金刚石片，其并不限于上述石墨材料。
具体的，导热片130可包括两个子导热片132，两个子导热片132相层叠，并且，两个子导热片132的同一侧均与散热器110相贴合。子导热片132均可为石墨等材料制成。
基板150为两个，两个基板150分别设置于两个子导热片132上。光源200也可为两个，两个光源200分别设置于两个基板150上。
可以理解，导热片130还可为一体成型的片状结构，而不限于上述两个子导热片132的结构。
具体在本实施例中，导热片130整体厚度为0.1~0.8毫米，以使得位于导热片130两侧的两个LED灯珠的间距更小。两个LED灯珠的间距越小，经过光学模拟测试所得到的光形就更好。
可以理解，导热片130还可通过其它具备高导热系数的材料进行取代，不限于石墨材料。导热片130的厚度可根据实际需求而改变。
此外，请再次参阅图1及图2，本发明还提供了一种汽车照明灯具10，汽车照明灯具10包括上述灯具散热机构100及光源200，光源200设置于的灯具散热机构100的基板150上。光源200包括LED灯珠。
具体在本实施例中，LED灯珠可为多个，多个LED灯珠排布于基板150上
上述汽车照明灯具10及灯具散热机构100，光源200产生的热量能够通过基板150及导热片130快速传递至散热器110，以将热量迅速发散出去，降低了灯具的温度，有助于灯具寿命的延长，无须频繁的对其进行保养或更换，进而降低了使用成本。
并且，导热片130可为石墨片130，石墨的导热系数高达1500W/(m•K)，因此，导热片130为石墨片130，可以加大导热片130的散热效率，更好的进行散热。
此外，导热片130整体的厚度为0.1~0.8毫米，以使得两个LED灯珠的间距更小，光形更好。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
