Description

灯具 技术领域
本发明涉及照明设备技术领域，尤其涉及一种灯具。
背景技术
灯具是人们生产生活中一种不可或缺的产品，灯具通常包括光源和电源，在灯具的工作过程中，电源和光源通常均会产生一定的热量，且电源和光源产生的热量还会相互影响，导致灯具的散热效率相对较低，造成灯具的使用寿命较短。
发明内容
本发明公开一种灯具，以解决目前灯具中光源和电源相互影响，整个灯具的散热效率较低，使用寿命较短的问题。
为了解决上述问题，本发明采用下述技术方案：
一种灯具，其包括：
外壳，所述外壳包括安装座、电源安装区和光源安装区，所述安装座配置为安装于灯杆，所述电源安装区和所述光源安装区均与所述安装座连接，且所述电源安装区和所述光源安装区之间设有散热孔，所述散热孔沿所述外壳的厚度方向贯穿所述外壳；
电源，所述电源安装于所述电源安装区；
发光组件，所述发光组件安装于所述光源安装区，所述发光组件包括透镜和光源，所述透镜与所述光源配合，且所述光源与所述电源电性连接。
本发明采用的技术方案能够达到以下有益效果：
本发明公开的灯具中，外壳上设置有安装座，在安装座的作用下，可以将整个灯具安装在灯杆上。外壳上的光源安装区和电源安装区分别用于安装发光组件和电源，由于电源安装区和光源安装区之间设置有散热孔，因而可 以使电源和发光组件隔绝开，使二者互相独立，防止在灯具的工作过程中，电源和发光组件产生的热量相互影响，提升电源和发光组件各自的散热效率；同时，由于散热孔沿外壳的厚度方向贯穿外壳，在灯具的工作过程中，气体可以在外壳的两侧流动，且带走电源和光源工作产生的热量，这可以进一步提升灯具的散热效率，达到提升灯具使用寿命的目的。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
以下结合附图，详细说明本发明各个实施例公开的技术方案。
如图1-图9所示，本发明实施例公开一种灯具，其包括外壳100、电源200和发光组件300。灯具可以为落地灯，或者灯具还可以为路灯的灯头。
其中，外壳100包括安装座110、电源安装区121和光源安装区122，安装座110配置为安装于灯杆400，电源安装区121和光源安装区122均与安装座110连接，且电源安装区121和光源安装区122之间设有散热孔140，散热孔140沿外壳100的厚度方向贯穿外壳100。电源200安装在电源安装区121，发光组件300安装在光源安装区122，发光组件300包括透镜310和光源320，透镜310与光源320配合，光源320与电源200电性连接。
在上述结构的情况下，整个灯具可以借助与外壳100连接的安装座110安装于灯杆400上。外壳100上的光源安装区122和电源安装区121分别用于安装发光组件300和电源200，由于电源安装区121和光源安装区122之间设置有散热孔140，因而可以使电源200和发光组件300隔绝开，电源200和发光组件300相互独立，在灯具的工作过程中，可以防止电源200和发光组件300各自产生的热量相互影响，进而提升电源200和发光组件300各自的散热效率；同时，由于散热孔140沿外壳100的厚度方向贯穿外壳100，在灯具的工作过程中，气体可以在外壳100的两侧流动，且带走电源200和 光源320工作产生的热量，这可以进一步提升灯具的散热效率，达到提升灯具使用寿命的目的。
具体地，外壳100的形状可以为长方形、正方形或圆形等。为了保证灯具具有较高的结构强度，外壳100和安装座110均可以采用塑料或金属等硬质材料制成，优选地，二者可以由金属材料经一体成型形成。安装座110与灯杆400等安装基础可以采用螺栓组件等连接件相互固定。散热孔140可以随外壳100的成型过程中直接形成，散热孔140的尺寸和形状均可以根据实际需求确定，可选地，散热孔140可以为方形孔，且散热孔140的数量为多个，多个散热孔140可以成行列式排布，在这种情况下，可以使散热孔140之间的连接结构的面积更小，进而增大散热孔140的散热面积，且可以减小整个外壳100的重量。
电源200与发光组件300中的光源320连接，为光源320配电，以使输入光源320的电流和电压等参数满足光源320的需求。光源320可以为LED灯，光源320的数量可以为一个，或者，光源320的数量还可以为多个，以提升整个灯具的照明效果。在光源320的为多个的情况下，多个光源320可以呈行列式排布，也可以交错排布，或者还可以呈同心圆式排布等。
透镜310为配光元件，以为光源320提供配光作用，透镜310可以具有光线扩散效果，以增大灯具的照明范围，或者，透镜310还可以提升光源320发出的光线的均匀度。透镜310可以采用亚克力等透光塑料制成，在光源320设置有多个的情况下，透镜310可以设置有一个，借助一个透镜310为多个光源320提供配光作用，或者，透镜310也可以设置有多个，多个透镜310与多个光源320一一对应设置，多个透镜310可以分体设置，或者多个透镜310相互连接为一体，这便于灯具加工和组装工作的进行。
需要说明的是，电源安装区121和光源安装区122均可以仅为安装位置，而无法为电源200和光源320提供封装或容纳的作用，在这种情况下，电源200、透镜310和光源320均可以借助螺钉等连接件固定在外壳100上。如上 所述，在灯具为路灯灯头的情况下，为了防止外界的水和灰尘进入电源200和光源320内，可以增设电源安装盒和光源安装盒，以为电源200和光源320提供封装作用。
为了提升灯具的整体性能，优选地，电源安装区121和光源安装区122二者还可以为电源200和光源320的安装提供容纳和封装的作用。进一步地，外壳100包括壳体120和盖体130，电源安装区121和光源安装区122均凹陷设置在壳体120上，盖体130盖设于电源安装区121，且围成电源容纳腔，电源200安装在电源容纳腔内；光源安装区122的开口处盖设有封装部，且围成光源容纳腔，光源320安装在光源容纳腔内，这使得灯具自身即具备容纳和封装电源200和光源320的作用，进而将水和灰尘等杂质隔绝在电源200和光源320之外。同时，可以使电源安装区121的开口和光源安装区122的开口分别位于壳体120的相背两侧，这使得灯具的空间利用效率能够得到有效提升。
具体地，电源安装区121和光源安装区122的形状和尺寸可以对应电源200和光源320的形状和尺寸。盖体130和壳体120之间，以及封装部和壳体120之间可以通过螺栓组件连接，或者，还可以通过卡接或粘接等方式固定在一起。
进一步地，封装部可以为硬质透光板，在这种情况下，透镜310和光源320均可以被封装在光源安装腔内。或者，封装部即为透镜310，透镜310能够封装在光源安装区122的开口处，这可以减少灯具中零部件的数量，且可以在一定程度上降低额外的部件对光源320发出的光线产生阻挡和削弱作用。
可选地，盖体130和壳体120之间，以及透镜310和壳体120之间均可以通过卡接的方式固定为一体。例如，盖体130和壳体120二者中，一者上可以设置有卡扣，另一者上可以设置有凸起，从而通过使卡扣产生一定的弹性形变而与凸起形成卡接限位关系，即可将壳体120和盖体130固定为一体， 相似的，壳体120和透镜310二者可以采用类似的连接方式相互固定。
具体地，壳体120上可以设置有第一卡扣510和第二凸起540，盖体130上对应第一卡扣510设置有第一凸起530，透镜310上对应第二凸起540设置有第二卡扣520，第一卡扣510和第一凸起530卡接连接，第二卡扣520和第二凸起540卡接连接，即可将盖体130和透镜310分别固定在壳体120上电源安装区121的开口和光源安装区122的开口处，实现封装电源200和光源320的目的。并且，这种结构的卡接限位关系便于拆卸，且无需借助工具。
另外，盖体130上第一凸起530的位置处还可以设置有限位结构，限位结构具有开口，第一凸起530可以设置在前述开口内，在连接壳体120和盖体130的过程中，第一卡扣510伸入前述开口与第一凸起530卡接固定，在限位结构的作用下，还可以防止第一卡扣510与第一凸起530之间的连接失效，保证壳体120和盖体130之间具有较高的连接可靠性。同样地，透镜310或壳体120上也可以设置有类似的限位结构，以保证透镜310和壳体120之间的连接关系具有较高的可靠性。
为了保证壳体120和盖体130之间，以及壳体120和透镜310之间均具有较高的连接可靠性，第一卡扣510、第二卡扣520、第一凸起530和第二凸起540均可以设置有多个，且多个第一卡扣510和多个第一凸起530一一对应配合，多个第二卡扣520和多个第二凸起540一一对应配合。多个第一卡扣510和多个第二卡扣520分别可以设置在壳体120和透镜310的不同方位处，以进一步提升壳体120和盖体130之间的连接可靠性。
为了进一步提升壳体120和盖体130之间的密封性能，可选地，盖体130朝向壳体120的表面可以设有容纳槽，且在容纳槽内设置密封圈150，通过使壳体120伸入容纳槽，且使壳体120与密封圈150挤压配合可以进一步提升壳体120和盖体130之间的气密性，进而防止水和灰尘进入电源200密封腔，对电源200的正常工作产生不利影响。
具体地，容纳槽可以随盖体130的形成过程一体形成，密封圈150可以采用橡胶或泡棉等柔性材料制成，在灯具的组装过程中，将密封圈150塞入盖体130的容纳槽内，且在连接盖体130和壳体120的过程中，使壳体120伸入容纳槽内。在壳体120和盖体130相互挤压的情况下，可以保证盖体130和壳体120之间具有较高的气密性。
相应地，发光组件300还可以包括密封垫340，密封垫340为环形结构，密封垫340密封连接在透镜310和壳体120之间，在密封垫340的作用下，透镜310和壳体120之间的密封性能也相应提升。具体地，密封垫340可以为橡胶或泡棉等柔性材料制成，密封垫340可以夹设于透镜310和壳体120之间，在第二卡扣520和第二凸起540相互连接之后，可以使密封垫340固定于透镜310和壳体120之间，且可以通过设计第二卡扣520、第二凸起540和密封垫340等部件的尺寸，使夹设固定于第二卡扣520和第二凸起540之间的密封垫340产生一定的弹性形变，以提升壳体120和透镜310之间的密封性能。
进一步地，透镜310可以包括透光部311和封装边沿312，封装边沿312连接于透光部311的外周，在组装灯具的过程中，可以使密封垫340套设在透光部311的外周，且使密封垫340和至少部分透光部311伸入至凹陷设置于壳体120上的光源安装区122内。同时，沿垂直于外壳100的厚度方向的方向，使密封垫340夹设于壳体120和透光部311之间，沿外壳100的厚度方向，所封装边沿312与壳体120贴合设置。
采用上述结构的情况下，外壳100、透镜310和密封垫340三者可以为光源安装区122提供多次密封。详细地，封边边沿连接在透光部311的外周，且至少部分透光部311伸入至光源安装区122内，封装边沿312与壳体120沿外壳100的厚度方向贴合设置，可以为光源安装区122提供一次密封；通过使密封垫340沿垂直于外壳100的厚度方向的方向夹设于壳体120和透光布置，可以为光源安装区122提供二次密封，同时，在密封垫340的作用下， 还可以提升透光部311和壳体120之间的固定连接效果。
为了进一步提升灯具的散热效率，电源200可以通过导热胶粘接于盖体130朝向壳体120的表面，这使得电源200因工作产生的热量可以在导热胶的作用下传递至盖体130上，进而通过盖体130散发处出去，进一步提升电源200的散热效率，从而进一步防止电源200产生的热量对光源320的散热过程产生不利影响，提升整个灯具的散热效率。
可选地，电源200粘接于盖体130表面的情况下，可以使电源200不与壳体120接触，从而进一步防止电源200产生的热量对光源320的散热过程产生不利影响；或者，也可以使电源200在粘接在盖体130上的同时还支撑于壳体120上电源安装区121的底部，从而提升电源200的安装稳定性。
如上所述，电源200的数量可以设置有多个，多个电源200可以提升灯具的照明效果，尤其是在灯具为路灯灯头的情况下，更好的照明效果可以在夜间为行人和来往的车辆提升可靠的照明作用。具体地，多个光源320可以安装在同一光源安装区122，可选地，光源安装区122可以设置有多个，多个光源320安装可以设置在电源安装区121的同一侧，也可以设置在电源安装区121的相对两侧，在电源安装区121的两侧均设置有光源安装区122的情况下，为了保证各光源安装区122所安装的发光组件300的散热效果均相对较高，可以使在各光源安装区122和电源安装区121之间设置散热孔140，这使得各光源安装区122所安装的发光组件300均与电源200相互独立，从而防止电源200和各光源320因工作产生的热量相互影响，而造成灯具的整体散热效果较差。
具体地，位于电源安装区121两侧的光源安装区122的形状可以相同，且光源安装区122内安装的发光组件300的规格也相同，这使得整个灯具的重心相对稳定，且使整个灯具所发出的光线的均匀度相对较高，光照效果较好。
进一步地，电源安装区121一侧可以设置有多个光源安装区122，且各 光源安装区122均安装有发光组件300，任一光源安装区122与电源安装区121之间均设有散热孔140，且任意相邻的两个光源安装区122之间也设置有散热孔140，在这种情况下，光源安装区122的数量得到进一步增加，并且，通过使任一光源安装区122与其他光源安装区122和电源安装区121均相互独立的方式，也可以保证整个灯具的散热效率相对较高，且还可以提升照明效果。
具体地，电源安装区121两侧的任一侧可以设置有数量相同的光源安装区122，各光源安装区122的形状和尺寸均可以完全相同，且可以使多个光源安装区122呈行列式排布，这可以进一步提升灯具的照明效果。更具体地，任一发光组件300内均可以包括多个光源320，透镜310上光源320对应的设置有多个配光结构，从而为多个光源320一一配光。在发光组件300设置有多个，且结构相同的情况下，为了提升灯具的组装效率，可以在透镜310和/或光源320上设置防呆结构330。
为了使整个灯具的散热效果更好，在电源安装区121两侧均设置有光源安装区122的情况下，沿外壳100的厚度方向，可以使电源安装区121的投影位于电源安装区121两侧的光源安装区122之外，在这种情况下，可以进一步防止电源200和光源320产生的热量相互影响而不利于电源200和光源320的散热工作的进行。
进一步地，可以使安装座110与壳体120上电源安装区121所在的位置处连接，这使得安装座110相对壳体120居中设置，从而保证安装座110的受力较为均衡，能够为整个灯具提供较为可靠的固定效果。
进一步地，安装座110可以包括容纳部111和定位部112，容纳部111具有灯杆腔111a，灯杆腔111a可以容纳灯杆400的一部分，以保证安装座110与灯杆400之间具有较为可靠的固定关系；定位部112安装在容纳部111上，且定位部112上设置有定位孔112a，在灯杆400与安装座110的组装过程中，灯杆400可以穿过定位孔112a且伸入至灯杆腔111a内，同时，在垂 直于定位孔112a轴向的方向上，定位孔112a可以与灯杆400形成限位配合关系，从而保证灯杆400与安装座110形成更为可靠的固定关系，防止安装于灯杆400上的灯具存在晃动的情况。
具体地，容纳部111与壳体120可以采用一体成型的方式形成，以保证二者之间具有较高的连接可靠性。定位部112可以为板状结构，其可以借助螺钉等连接件固定安装在容纳部111上，且定位孔112a的尺寸可以根据灯杆400的尺寸和形状等实际情况灵活设计。
