Description
一种LED灯具
技术领域
[0001] 本发明涉及LED照明领域，更具体地说，涉及一种LED灯具。 背景技术
[0002] LED发光体作为第五代光源，具有节能、环保、寿命长、体积小等特点，可以广泛应 用于各种指示、显示、装饰、背光源、普通照明和城市夜景等领域。LED发光体在工作时会产 生大量的热，如果这些热量不能及时的导走，会导致LED发光体温度过高，从而降低LED的 光通降低和使用寿命减小，所以LED发光体的散热问题是限制LED应用的一个关键因素。 [0003] 目前针对大功率LED灯具， 一般是增加散热风扇，或者在灯具的外侧增大散热板 的面积。对于有防爆要求的灯具，增加风扇不符合防爆的标准，而且风扇的寿命与LED的寿 命不匹配；单纯的增大散热板的面积则会导致灯具体积过大，影响灯具的外观和安装。
发明内容
[0004] 本发明要解决的技术问题在于，针对现有技术LED灯具的上述散热不合理的缺陷 缺陷，提供一种散热结构合理的LED灯具。
[0005] 本发明解决其技术问题所采用的技术方案是：构造一种LED灯具，包括金属灯体，
所述金属灯体具有用于贴装LED发光体的安装面，其特征在于，所述金属灯体还具有由上
到下贯穿所述金属灯体的散热通道，所述散热通道的上端和下端分别于大气连通。
[0006] 在本发明所述的LED灯具中，所述散热通道的内壁上设置有多条沿所述散热通道
方向延伸的散热鳍片。
[0007] 在本发明所述的LED灯具中，所述金属灯体具有一锥形台，所述安装面为锥形台
的锥面，所述散热通道沿所述锥形台的轴线贯穿锥形台。
[0008] 在本发明所述的LED灯具中，所述锥形台为圆锥台或多棱锥台。
[0009] 在本发明所述的LED灯具中，所述金属灯体由金属材料铸造而成。
[0010] 在本发明所述的LED灯具中，所述锥形台具有连通锥面和散热通道的导线通道。
[0011] 在本发明所述的LED灯具中，所述导线通道内设置有防水胶套。
[0012] 在本发明所述的LED灯具中，所述LED灯具还包括透明或半透明的灯罩，所述灯罩
罩住所述锥形台，所述灯罩上具有正对所述散热通道的通孔。
[0013] 在本发明所述的LED灯具中，所述锥形台的根部具有一凸缘，所述LED灯具还包括 第一压环和第二压环，所述第一压环将所述灯罩的开口端固定在所述凸缘上，所述第二压 环将所述灯罩的底部固定在所述锥形台的锥顶。
[0014] 在本发明所述的LED灯具中，所述安装面与竖直方向的夹角为45度。 [0015] 实施本发明的LED灯具，具有以下有益效果：本发明的LED灯具在其金属灯体上具 有由上到下贯穿灯体的散热通道，贴装金属灯体上的LED工作时产生的热量由金属灯体传 导到散热通道，散热通道内的空气加热后上升形成空气对流，加快金属灯体的散热，能够满 足大功率LED发光体的散热需要。附图说明
[0016] 下面将结合附图及实施例对本发明作进一步说明，附图中：
[0017] 图1是本发明的LED灯具第一实施例的金属灯体的剖视图；
[0018] 图2是本发明的LED灯具第一实施例的剖视图；
[0019] 图3是本发明的LED灯具第一实施例的示意图；
[0020] 图4是本发明的LED灯具第一实施例的灯罩的示意图；
[0021] 图5是本发明的LED灯具第一实施例中第一压环的示意图；
[0022] 图6是本发明的LED灯具第一实施例中第二压环的示意图；
[0023] 图7是本发明的LED灯具的第二实施例的剖视图。
具体实施方式
[0024] 如图1、图2和图3所示，在本发明的LED灯具的第一实施例中，金属灯体1为铸造 件，可由铁、铝、铜、铝合金以及其他具有良好导热性的金属或合金铸成，保证金属灯体1具 有良好的导热性能。金属灯体的下部为锥形台10，在本实施例中为一个八棱锥的棱锥台，每 个锥面11为贴装LED发光体20的安装面，贴装在安装面上的LED发光体20产生的热量传 递给金属灯体1，由金属灯体1向外散热。为了改善金属灯体1的散热效果，金属灯体1具 有由上到下贯穿金属灯体1的散热通道12，散热通道12的上端和下端分别与大气相连通， 散热通道12沿锥形台10的轴线贯穿锥形台。当LED发光体20工作时，其产生的热量传导 到金属灯体1上，散热通道12内的空气被金属灯体1加热后由于比重减小而上升，在散热 通道内形成上升气流将热量带走，下部的冷空气被吸入与散热通道12的内壁进行热交换， 如此循环，能够有效的改善金属灯体l的散热，满足大功率LED发光体的散热需要。为了进 一步改善散热的效果，在散热通道12的内壁设置有多条沿散热通道12方向延伸的散热鳍 片121，散热鳍片121的存在，大大增加了散热通道12与空气的热交换面积，进一步提高了 散热效率。参看图3，为了使散热通道12与顶部的连接部13不发生干涉，在金属灯体1的 上部侧面上开设有两个通孔122，通孔122与散热通道12相连通，实际应用中，也可以在图 1中123所示的位置开设通孔，使散热通道12与外部保持连通。
[0025] 参看图2、图3、图4、图5和图6，为了保护LED发光体20，在本实施例中，还包括一 灯罩30，灯罩30为有机玻璃制成，可以根据需要选择透明或半透明，灯罩30的底部31正对 散热通道12的地方具有一通孔311，用于保证灯罩30罩住锥形台10之后，散热通道12通 过通孔311与外部保持连通。透明灯罩30通过第一压环41和第二压环42固定在金属灯 体1上，具体是锥形台10的根部具有一凸缘14，灯罩30的开口端的边缘32被第一压环41 压在凸缘14上，第一压环41与凸缘14通过螺钉固定，灯罩30底部31通过第二压环42压 在锥形台10的锥顶15上，第二压环42与锥顶通过螺钉连接。在本实施中，LED发光体20 的导线可以有由灯罩30底部31与锥顶15之间进入到散热通道12中，并由散热通道中引 出。
[0026] 如图7所示，为本发明的LED灯具的第二实施例，第二实施例的结构基本与第一实 施例的结构相同，不同之处在于，为了方便导线引出，并保证导线引出的可靠性，金属灯体l 的锥形台10的锥面上开设有连通锥面和散热通道12的导线通道16，并在导线通道16内设置有防水胶套17， LED发光体20的导线穿过防水胶套17进入散热通道12，并由散热通道 12引出。
[0027] 在本发明的LED灯具的第一和第二实施例中，锥形台都是多棱锥台，实际中也可 以采用圆锥台，LED发光体贴装在圆锥面上。无论是圆锥台还是多棱锥台，为了保证灯具具 有更好的照明效果，锥面与竖直方向夹角为45度，这样在锥面上贴装LED发光体之后，可以 保证光照中心不会出现空洞或暗斑。
[0028] 上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体 实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员 在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多 形式，这些均属于本发明的保护之内。
