  • the heat sink is a semi-circular cylinder, and the semi-circular surface is processed into the shape of a hollow grid, which increases its contact area with air, and further optimizes heat conduction. Because LED lamps are in the heat dissipation process, the most important thing is the convection heat transfer between the radiator and the air. Under the influence of external winds, natural convection is mainly relied on. Natural convection is caused by the cold air that is in contact with the radiator and is naturally heated by the radiator. The surrounding cold air continues to be replenished and continuously circulates to carry away the heat. By setting the shape of the hollow grille and increasing the contact area with the air, the heat on the heat sink can be removed to the utmost extent.

If the size of the radiator is too large, the hot air in the middle part will rise and there will not be enough cold air around it to be replenished. In this case, the heat dissipation efficiency of the middle portion is lowered, the temperature is increased, and the life of the "heat island effect" light source is lowered. With this in mind, the design of the size of the heat sink does not produce a heat island effect while maximizing the heat dissipation efficiency.

具体实施方式
本发明提供的新型道路照明用灯照明组件，其包括：驱动电源、固定支座、胶圈、水平仪、基座、散热器、堵头、LED光源和透镜。
本发明提供的新型道路照明用灯照明组件，其包括：驱动电源、支座、 水平仪、散热器、堵头、LED光源和透镜。
所述驱动电源与散热器通过支座相连接，散热器与LED光源相连接，这三者构成了灯照明组件的主体结构。
所述LED光源和所述散热器构成光源组件。
在本发明中，驱动电源与基座连接，基座与固定支座相连接，在固定支座和基座的连接位置处设置胶圈，固定支座还与散热器相连接，LED光源通过包含石墨烯的导热硅脂贴合在散热器的水平端面上并固定，透镜固定安装在散热器的水平端面上，LED光源设置在散热器和透镜之间。
在另一个实施方式中，驱动电源与支座连接，支座进一步与散热器相连接，LED光源通过包含石墨烯的导热硅脂贴合在所述散热器的水平端面上并固定，透镜固定安装在所述散热器的水平端面上，LED光源设置在所述散热器和透镜之间。
在一个具体的实施方式中，所述驱动电源与所述基座通过螺丝连接固定，所述基座与所述固定支座相连接，在所述固定支座和所述基座的连接位置处设置胶圈，用于两处密封连接，所述固定支座进一步与散热器相连接，所述堵头通过螺丝安装在散热器的前端，作为前盖使用。
将水平仪设置在基座上部，基座与驱动电源接触连接的位置处。
所述光源通过包含石墨烯的导热硅脂贴合在散热器的水平端面上，进一步通过例如螺丝固定，所述透镜通过例如螺丝固定安装在散热器的水平端面上，将光源设置在散热器和透镜之间。在光源和散热器之间设置包含石墨烯的导热硅脂用于实现传热，降低热阻。所采用的包含石墨烯的导热硅脂材料在申请人之前的专利CN201210119361.9已经公开，在此不再详述。
所述散热器优选采用铝材料或者市售的任何铝合金材料制作，此外也可选择陶瓷材料、铁材料。这是散热器起到热传导的主要媒介。
所述散热器是半圆形柱体，半圆形表面加工成镂空格栅的形状，增加了其与空气的接触面积，进一步优化了热量的传导。因为LED灯具在散热过程，最主要还是靠散热器和空气的对流换热。在排除外界风力的影响下主要还是靠自然对流。自然对流是靠和散热器接触的冷空气被散热器加热后自然上升，周围的冷空气继续补充进来，不断循环把热量带走。通过设置镂空格栅的形状，增加与空气的接触面积，可以最大限度的带走散热器上的热量。
但是散热器的尺寸也会影响到散热效果。如果散热器尺寸过大的话，其 中间部分的热空气上升后，周围并没有足够的冷空气可以补充进来。这种情况下，就会导致中间部分散热效率低下，温度升高，形成“热岛效应”光源寿命会降低。考虑到这一点，对于散热器的尺寸的设计，在最大化保证散热效率的同时，又不能产生热岛效应。经我们研究发现，散热器形状不变的情况下，就散热器水平长方形纵截面尺寸而言，该长方形纵截面的长度为100～300mm，优选为150～250mm，进一步优选为180～220mm，例如可以为190mm，195mm、200mm，205mm、210mm等等，其宽度为20mm～80mm，优选为30～70mm，进一步优选为40～60mm，可以为45mm，46mm、47mm、48mm、49mm、50mm，51mm、52mm、53mm、54mm、55mm等等。该散热器是半圆形柱体，其横切面的半圆形的半径通常为10～40mm，优选为15～35mm，进一步优选为20～30mm，可以为21mm、22mm、23mm、24mm、25mm、26mm、27mm、28mm、29mm、30mm等等。通常尺寸控制在上述范围散热效果是相对较好的，通过大量的尝试，采用这个尺寸也便于后期安装操作，更方便的放入到钠灯壳中。
在形状和尺寸优化的前提下，为了进一步增加热传导和热辐射率，在本发明中将含有石墨烯的氟树脂复合材料与散热器结合起来。通过采用含有石墨烯的氟树脂散热材料喷涂在散热器的半圆形的外表面，提升了散热器的散热效率。所采用的包含石墨烯的氟树脂复合材料(也可以称为RLCP石墨烯氟树脂复合材料)在申请人之前的专利CN201310089504.0已经公开，在此不再详述。
所述电源部件，采用的是高效率，高功率因数的恒流隔离驱动电源，由多个电子元器件组成的一个整体。该电源部件采用圆柱型一体化的设计，美观的同时，该柱体是一个高度5-6cm的中空圆柱体，保证驱动电源良好散热的同时，不让电子元器件暴露在外面，提高了安全系数。驱动电源工作时产生的热量以热传导的方式传递给固定的散热器，再以辐射及对流的形式进行散热，防止电源核心电气元件的受损，提高了驱动电源的使用寿命。
所述LED光源部件，可以采用各种类型的灯光源，优选COB光源，是一种集成灯珠。相比普通LED灯珠，COB集成光源光效更高，色容差小。并且COB光源的芯片优选采用倒装技术的COB光源，倒装技术取消了蓝宝石衬底，减少了热阻，进一步提升了LED灯的散热功能。
本发明提供的所述COB光源的灯珠以一字型分布在基板上，经过大量 筛选，考虑热量问题，基板选用的材质为超导铝，在热传导效率方面达到最佳的效果。进一步降低光衰，延长使用寿命。
本发明提供的透镜的材料可以为玻璃、PC或PMMA，优选为玻璃。
目前，大部分LED灯发出的光是呈郎伯型分布，中心光强比较强，而且为对称的圆形光斑分布，不能用于直接的道路照明。本发明优化了透镜，直接在二次光学透镜上做配光，配光呈蝠翼型分布，光照均匀，防止出现眩光现象、并且出光效率达到95％以上，并且用于固定LED的载体PCB基板可以采用任何符合设计需求的形状，外观可以多样化。
所述固定支架可以为任意的导热性，结构良好的材料，优选铜、铁、陶瓷、铝以及相应的合金材料，进一步优选铝及其合金材料、陶瓷，最优选铝合金材料。本发明中固定支架采用铝合金材质，强化了热传导和热辐射的效果，本发明将支架整体设计成与散热器截面高度贴合并且契合面形状一样的半圆型。安装操作时，通过螺丝将照明组件结构牢牢固定在固定支座上，再将固定支架与基座通过螺丝进行连接。散热器与空气传递热量的同时，一部分热量以热传导的形式传递给固定支架，固定支架弧形的表面，与散热器高度贴合，最薄贴合处距离达到0.3cm。一方面起到固定作用的同时，固定支架还分担传递了来自光源工作产生的热量，降低了光衰发生速率，延长了使用寿命。
连接固定支架与驱动电源的基座部件材质可为尼龙、金属、PTFE任意其中一种。本发明中优选PTFE，考虑到灯具是暴露的形式安装在周围环境当中，要与空气中的物质发生化学反应，从而产生腐蚀老化等现象，选用PTFE材料可以最大限度的降低腐蚀老化情况的发生。此外，因为PTFE的热阻非常大，可以更好的避免前端散热器与驱动电源之间相互热影响、热干扰。
基座整体结构设计成中间沉降的柱体，考虑到灯具安装角度的特殊性，又有来自水平力矩的影响。经实验发现，基座柱体中间结构下沉距离5cm至6cm时是稳定性最好的。这种结构起到稳定连接的作用，且固定支架不影响安装操作。
如果支座为一体成型结构时，支座采用铝合金或其他材质，优选铝合金材质。
所述堵头的材质可为尼龙、金属、PTFE任意一种。本发明中也优选了 铝合金，使得灯具整体显得更加的协调与美观，也进一步加速了对于散热器热量的传递，起到辅助散热的作用。考虑到灯具是封闭的形式安装在周围环境当中，使用周期一长，难免要与空气中的物质发生化学反应，也会从内部产生腐蚀老化等现象。由于散热器采用一体化的加工，散热器的顶部处会存在毛刺，给安装操作的人员带来一定的安全隐患的同时，美观的程度也会下降，为了解决这个问题，将堵头设计成紧贴散热器顶部半圆形状，且堵头重量控制在250克至300克的范围，避免产生一定的力矩，影响灯具安装的稳定性。
所述水平仪为任何市售水准泡，形状可为圆柱型、方形等任意形状。材质选为塑料。本发明优化了安装操作过程，考虑到灯具整体特殊的安装角度，将水平仪与基座结合起来，将水平仪设置在基座上部，位于基座与驱动电源接触连接的位置处，离驱动电源最低端距离6cm-7cm处。让水平仪达到最佳使用效果。也在安装操作的过程中，给予安装操作人员一个水平的参考值，衡量是否安装到位。从侧面加强了灯具的整体稳定性，提高了安全系数。
本发明还提供一种道路照明用灯，其包括灯壳和照明组件，所述灯壳可以采用传统钠灯灯壳。
所述照明用灯还具有支架和反光罩，反光罩通过螺丝固定安装在灯壳内，在反光罩的尾部设有圆形口，供照明组件穿过。
照明组件外接在支架上，支架通过螺丝固定在灯壳上。
以下采用实施例和附图来详细说明本实用新型的实施方式，借此对本实用新型如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。
如图1所示，本发明提供的新型道路照明用灯照明组件，其包括：驱动电源1、固定支座2、胶圈3、水平仪4、基座5、散热器7、堵头8、LED光源9和透镜10。所述驱动电源1与所述基座2通过螺丝6连接固定，所述基座5与所述固定支座2相连接，在所述固定支座2和所述基座5的连接中间位置处设置胶圈3，用于两处密封连接。此外虽然图1中画出了基座5与固定支座2为彼此分开的结构，但是也可以将这两个结构统一制模，以一个构件的形式出现，此时也可以将其称为支座。所述固定支座2进一步与散热器7相连接，所述堵头8通过螺丝6安装在散热器的前端，作为前盖使用。将水平仪设置在基座5上部，基座5与驱动电源1接触连接的位置处。所述 透镜10通过螺丝固定安装在散热器的水平端面上，将光源9设置在散热器7和透镜10之间，通过包含石墨烯的导热硅脂贴合在散热器7的水平端面上，一步通过螺丝固定。在所述散热器7的半圆形外表面的整个表面上喷涂包含石墨烯的氟树脂复合材料。

热线法：GB10297-88非金属固体材料导热系数的测定方法。多路温度测试仪热电偶分别连接在光源基板、散热器翅片处，点亮样品持续120分钟，设定每隔10分钟记录当前温度。对比实施例1和实施例2温差，结果数据如表1所示。
表1

针对实施例1，可以看出，通过将散热器设置成半圆形柱体，实施例1的得到的道路照明用灯组件，实现了一体化的结构设计，缩小了灯组件的安 装体积，在实施例1的灯具上配以传统的钠灯或LED灯通用连接部件，达到与传统路灯内部光源总成的结构紧密连接。
而实施例2中进一步组入两种石墨烯材料，从表1中可以看出使用石墨烯材料的实施例2的光源基板温升明显比未使用石墨烯材料实施例1的样品缓慢，最终稳定状态下温差达13℃，说明使用石墨烯材料后系统散热能力较强；从光源基板与散热器翅片温差可以看出，喷涂石墨烯材料后温差在3℃左右，而未喷涂温差达到6℃左右，可见使用石墨烯材料后系统具有了更好的热辐射能力，降低了LED芯片温度。可见本发明通过进一步添加RLCP氟树脂复合材料涂层和石墨烯导热硅脂材料更进一步提升了光源光效，降低了光衰，提高了散热器的散热效率。
综上，本发明提供了一种光源组件、照明组件以及道路照明用灯，在本发明的光源组件、照明组件以及道路照明用灯中使用的散热器设置成半圆形柱体。本发明通过一体化的结构设计，缩小了安装体积，在本发明的灯具上配以传统的钠灯或LED灯通用连接部件，达到与传统路灯内部光源总成的结构紧密连接。本发明的灯具将多颗大功率LED灯珠集成在一块基板上，配以特定配光的一体式透镜，另配合散热器结构的设计并加以导热、储热、散热材料的应用，解决了传统路灯及普通LED路灯的缺点，并达到低光衰、高光效、高节能率、长寿命及快速无损替换等优点。
所有上述的首要实施这一知识产权，并没有设定限制其他形式的实施这种新产品和/或新方法。本领域技术人员将利用这一重要信息，上述内容修改，以实现类似的执行情况。但是，所有修改或改造基于本发明新产品属于保留的权利。
以上所述，仅是本发明的较佳实施例而已，并非是对本发明作其它形式的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例。但是凡是未脱离本发明技术方案内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与改型，仍属于本发明技术方案的保护范围。
