为了更清楚地说明本发明实施例或现有技术中的技术方案， 以下将对实施 例或现有技术描述中所需要使用的附图进行论述， 显然， 在结合附图进行描述 的技术方案仅仅是本发明的一些实施例， 对于本领域普通技术人员而言， 在不 付出创造性劳动的前提下，还可以根据这些附图所示实施例得到其它的实施例 及其附图。

以下将结合附图对本发明的各实施例的技术方案进行清楚、 完整的描述， 显然， 所描述的实施例仅仅是本发明的一部分实施例， 而不是全部的实施例。 基于本发明中所述的实施例， 本领域普通技术人员在不需要创造性劳动的前提 下所得到的所有其它实施例， 都在本发明所保护的范围内。
根据本发明的一个方面， 提供一种具有散热功能的玻璃照明灯， 包括： 灯头；
λτ_¾.；
灯杯， 其具有连接到所述灯头的上开口和连接到所述灯盖的下开口； 和 发光组件， 其安装在由所述灯杯和所述灯盖限定的内空间中；
其中， 所述灯杯的侧壁的下部分或所述下开口具有从所述内空间通向所述 玻璃照明灯外的进气口， 所述灯杯的侧壁的上部分或所述上开口具有从所述内 空间通向所述玻璃照明灯外的出气口， 所述进气口与所述出气口在所述内空间 中连通。
这样， 从灯杯的进气口经由灯杯内空间到灯杯的出气口， 形成散热路径。 发光组件工作（发光）时会散发出一部分热量， 由此被加热的空气会上升而从 上方出气口排出， 使得灯内 （灯杯内空间中）的气压降低， 灯外的较冷空气在 灯内外压力差的作用下从下方进气口被吸入灯内， 并在被发光组件加热后上升 而从上方出气口排出。 这样， 利用烟囱效应， 外部较冷空气经由下方进气口被 吸入灯内， 在玻璃照明灯的内空间中被发光组件的散热加热之后上升， 并可经 由上方出气口排出灯外， 由此实现沿所述散热路径的散热循环而实现对流， 从 而能够连续不断地将由发光组件散发的热量排出到灯外， 因而使本发明所提供 的玻璃照明灯具有良好的散热性， 以确保玻璃照明灯的正常工作。
应理解， 进气口既可以设置在灯杯侧壁的下部分上以形成连通灯内灯外的 通孔， 也可以设置在灯杯下开口边缘处以形成连通灯内灯外的凹口； 类似地， 出气口既可以设置在灯杯侧壁的上部分上以形成连通灯内灯外的通孔，也可以 设置在灯杯上开口边缘处以形成连通灯内灯外的凹口。
下方的进气口和上方的出气口的数量可以相同也可以不同。 不过， 灯杯的 下部分（延伸到与灯盖连接的下开口）和上部分（延伸到与灯头连接的上开口） 在尺寸上可能不同， 例如， 下部分大于上部分， 或者下开口大于上开口， 因此， 由于在空间布置上的限制， 下方的进气口可以多于上方的出气口。
图 1是根据本发明的第一实施例的具有散热功能的玻璃照明灯的剖视图。 在图 1所示的实施例中， 所述玻璃照明灯包括：
灯头 100;
灯盖 500;
灯杯 400,其具有连接到所述灯头 100的上开口 401和连接到所述灯盖 500 的下开口 402; 和
发光组件 300,其安装在由所述灯杯 400和所述灯盖 500限定的内空间 440 中；
其中， 所述灯杯 400的侧壁的下部分或所述下开口 402具有从所述内空间 440通向所述玻璃照明灯外的进气口 412, 所述灯杯的侧壁的上部分或所述上 开口 401具有从所述内空间 440通向所述玻璃照明灯外的出气口 411 , 所述进 气口 412与所述出气口 411在所述内空间 440中连通。
这样， 从灯杯进气口 412经由灯杯内空间 440到灯杯的出气口 411 , 形成 散热路径。 发光组件 300工作（发光）时会散发出一部分热量， 由此被加热的 空气会上升而从上方出气口 411排出， 使得灯内 （灯杯内空间 440中）的气压 降低，灯外的较冷空气在灯内外压力差的作用下从下方进气口 412被吸入灯内， 并在被发光组件 300加热后上升而从上方出气口 411排出。 这样， 利用烟囱效 应 ,外部较冷空气经由下方进气口 412被吸入灯内 ,在玻璃照明灯的内空间 440 中被发光组件 300的散热加热之后上升， 并可经由上方出气口 411排出灯外， 由此实现沿所述散热路径的散热循环而实现对流，从而能够连续不断地将由发 光组件 300散发的热量排出到灯外， 因而使本发明所提供的玻璃照明灯具有良 好的散热性， 以确保玻璃照明灯的正常工作。
在图 1所示的实施例中可见， 进气口 412设置在灯杯下开口 402边缘处以 形成连通灯内灯外的凹口； 类似地， 出气口 411设置在灯杯上开口 401边缘处 以形成连通灯内灯外的凹口。
较佳地， 在本发明的各实施例中， 所述的具有散热功能的玻璃照明灯可进 一步包括：
引导通路， 其设置在所述灯杯的内壁上， 并沿从所述进气口到所述出气口 的方向延伸； 其中， 所述引导通道从所述进气口延伸到所述出气口， 或者所述 弓 ]导通道的至少一端与所述进气口或出气口分开一段距离。
为了增强散热循环， 可在灯杯的进气口与出气口之间设置引导通路， 引导 从进气口被吸入灯内的空气从出气口排出。 应理解， 引导通道既可以是在进气 口与出气口之间全程延伸的完整的引导通道，也可以是在进气口与出气口之间 部分延伸的引导通道（即， 引导通道的一端或两端可以与进气口或出气口分开 一段距离）。 也就是说， 引导通道不必是封闭的通道。
在一个实施例中， 引导通道可以是连续延伸的； 但在另一实施例中， 引导 通道可以是断续延伸的， 即， 采用类似于虚线的形式， 以实现一定程度的气流 引导。
优选地所述引导通道在所述灯杯的内壁上的多条凸棱之间形成或者通过 所述灯杯的内壁上的凹槽形成。 这样， 所述引导通道既可以在灯杯内壁上相邻 的凸棱之间形成， 也可以由灯杯内壁上的凹槽直接形成。
在一个实施例中， 凸棱具有楔形形状， 所述楔形从所述灯杯的内壁沿径向 向内突起的高度沿从所述进气口到所述出气口的方向而变小。
应理解， 用于形成所述引导通道的凸棱可以是连续延伸的， 也可以是断续 延伸的， 以实现连续延伸或断续延伸的引导通道。 较佳地， 在本发明的各实施例中， 所述发光组件包括： 光源支架， 其安装 到所述灯杯的内壁上， 并处于所述进气口与所述出气口之间； 和光源， 其安装 在所述光源支架的朝向所述灯盖的一侧上， 其中：
在所述光源支架的边缘与所述灯杯的内壁之间形成沿所述玻璃照明灯的 轴向贯穿的空隙； 或
在所述光源支架的边缘与所述灯杯的内壁之间形成沿所述玻璃照明灯的 轴向贯穿的空隙， 且所述光源支架包括沿所述玻璃照明灯的轴向贯穿的通气 孔； 或
所述光源支架的边缘与所述灯杯的内壁封闭接触， 且所述光源支架包括沿 所述玻璃照明灯的轴向贯穿的通气孔。
这样， 安装在光源支架上的光源发射的光可经由灯盖发出灯外进行照射。 由于光源支架将由灯杯和灯盖限定的内空间大致分为沿玻璃照明灯轴向的上 下两个空间， 其中发光的光源处于光源支架与灯盖之间的下空间中， 因此， 为 了有效散热， 需要在上、 下空间之间形成沿玻璃照明灯轴向贯穿的边缘空隙和 /或通气孔，以在处于下空间中的进气口与处于上空间中的出气口之间保持散热 路径通畅， 从而利用烟囱效应将在下空间中被光源加热的空气排出灯外。
应理解， 玻璃照明灯的轴向是从灯盖、 灯杯下开口、 光源支架、 灯杯上开 口、 到灯头延伸的方向， 在这些部件具有圓形形状的情况下， 玻璃照明灯的轴 向可穿过灯盖、 灯杯下开口、 光源支架、 灯杯上开口、 灯头的中心而为对称轴 方向。
在图 1所示的实施例中， 所述发光组件 300包括： 光源支架 301 , 其安装 到所述灯杯 400的内壁上， 并处于所述进气口 412与所述出气口 411之间； 和 光源 303 , 其安装在所述光源支架 301的朝向所述灯盖 500的一侧上， 其中： 在所述光源支架 301的边缘（在图 1中显示为左右边缘）与所述灯杯 400的内 壁之间形成沿所述玻璃照明灯的轴向（在图 1中显示为大致上下方向）贯穿的 空隙。 由此， 在以光源支架 301为界的上、 下空间之间形成沿玻璃照明灯轴向 贯穿的边缘空隙， 以在处于下空间中的进气口 412 与处于上空间中的出气口 411之间保持散热路径通畅， 从而利用烟囱效应将在下空间中被光源 303加热 的空气排出灯外。
图 2是根据本发明的第二实施例的具有散热功能的玻璃照明灯的剖视图。 在图 2所示的第二实施例中， 与图 1所示的第一实施例相比， 在所述光源支架 301的边缘（在图 1中显示为左右边缘） 与所述灯杯 400的内壁封闭接触， 且 所述光源支架 301包括沿所述玻璃照明灯的轴向（在图 1中显示为大致上下方 向）贯穿的通气孔 305。 由此， 在以光源支架 301为界的上、 下空间之间形成 沿玻璃照明灯轴向贯穿的通气孔 305 , 在处于下空间中的进气口 412与处于上 空间中的出气口 411之间经由通气孔 305保持散热路径通畅， 从而利用烟囱效 应将在下空间中被光源 303加热的空气排出灯外。
应理解， 虽然在图 2所示的第二实施例中光源支架 301的边缘与灯杯 400 的内壁封闭接触，使得所述散热路径从进气口 412仅经由通气孔 305到出气口 411 实现空气流通， 不过在另一实施例中， 光源支架的边缘与所述灯杯的内壁 之间同时还可形成沿所述玻璃照明灯的轴向贯穿的空隙（其类似于在图 1所示 第一实施例中的大致轴向贯穿空隙）， 由此不仅形成与图 2所示第二实施例中 类似的从进气口 412经由通气孔 305到出气口 411的散热路径， 同时还形成与 图 1 所示第一实施例中类似的从进气口 412经由所述轴向贯穿空隙到出气口 411的散热路径， 从而更有利于空气流通散热。
较佳地， 在本发明的各实施例中， 所述通气孔相对于所述光源处于径向向 外的位置。 也就是说， 通气孔处于光源的径向外侧位置， 即， 与玻璃照明灯的 轴向 （轴线）的径向距离更远。 不过， 在其它实施例中， 特定的通气孔可能会 设置在光源的径向内侧位置， 即， 与玻璃照明灯的轴向 （轴线）的径向距离更 近， 或者设置为具有相同的径向距离。
优选地， 多个光源可在光源支架上以阵列形式安装排布。
图 5是根据本发明的一个实施例的具有散热功能的玻璃照明灯的发光组件 的示意图。 在图 5所示实施例中， 光源 303 (在图中显示为五个）安装在光源 支架 301上， 光源支架 301上未设置通气孔。 在这种情况下， 图 5所示的发光 组件可用于图 1所示的根据本发明第一实施例的玻璃照明灯中。
图 6是根据本发明的另一实施例的具有散热功能的玻璃照明灯的发光组件 的示意图。 在图 6所示实施例中， 光源 303 (在图中显示为五个）安装在光源 支架 301上， 光源支架 301上还设置多个通气孔 305。 在这种情况下， 图 6所 示的发光组件既可用于图 1所示的根据本发明第一实施例的玻璃照明灯中， 也 可用于图 2所示的根据本发明第二实施例的玻璃照明灯中。
在图 6所示的实施例中可见， 所述通气孔 305相对于所述光源 303 (或者 由多个光源 303构成的光源阵列）处于径向向外的位置。 在图 6所示的实施例 中， 多个通气孔 305沿光源 303 (或者由多个光源 303构成的光源阵列） 的外 圓周均匀布置。
较佳地， 在本发明的各实施例中， 所述灯杯的内壁包括台阶， 所述光源支 架安装到所述灯杯的台阶上。 这样， 光源支架的安装定位更加准确牢靠。 优选 地， 光源支架进一步通过胶粘方式安装到所述台阶上以增强牢固性。
较佳地， 在本发明的各实施例中， 多个所述进气口可沿所述灯杯的下开口 的边缘沿周向分布。 在这种情况下， 进气口可以是下开口边缘上形成的凹口， 且在下开口边缘上沿周向分布。
较佳地， 在本发明的各实施例中， 多个所述出气口可沿所述灯杯的上开口 的边缘沿周向分布。 在这种情况下， 进气口可以是上开口边缘上形成的凹口， 且在上开口边缘上沿周向分布。
应理解， 下开口边缘上的进气口和上开口边缘上的出气口的数量可以相同 也可以不同。 不过， 灯杯的下开口 （连接到灯盖）和上开口 （连接到灯头）在 尺寸上可能不同 （例如下开口大于上开口）， 因而由于在空间布置的限制， 在 下开口边缘上的进气口可多于在上开口边缘上的出气口。
图 3是根据本发明的实施例的具有散热功能的玻璃照明灯的灯杯的出气口 的示意图。 在图 3所示的俯视图中 （例如， 沿图 1 中从上向下的方向所见）， 多个所述出气口 411可沿所述灯杯 400的上开口的边缘沿周向分布， 在图 3中 显示为四个出气口 411沿灯杯 400的上开口的边缘沿周向均匀分布。
图 4是根据本发明的实施例的具有散热功能的玻璃照明灯的灯杯的进气口 的示意图。 在图 4所示的仰视图中 （例如， 沿图 1 中从下向上的方向所见）， 多个所述进气口 412可沿所述灯杯 400的下开口的边缘沿周向分布， 在图 4中 显示为八个出气口 412沿灯杯 400的下开口的边缘沿周向均匀分布。
在图 4所示实施例中可知， 下开口边缘上的进气口 412和上开口边缘上的 出气口 411的数量是不同的。 由于灯杯下开口 （连接到灯盖）通常大于上开口 (连接到灯头）， 因而由于在空间布置的限制， 在下开口边缘上的进气口 412 可多于在上开口边缘上的出气口 411。 在图 4所示的实施例中显示出八个进气 口 412和四个出气口 411。
较佳地， 在本发明的各实施例中， 多个所述通气孔沿所述光源支架的边缘 沿周向分布。 在这种情况下， 通气孔实际上可以是在光源支架的边缘上形成的 凹口， 且在光源支架边缘上沿周向分布， 由此与灯杯内壁之间形成沿玻璃照明 灯的轴向贯穿的空隙。
在一个优选实施例中， 所述光源支架为光源支板。
较佳地， 在本发明的各实施例中， 多个所述进气口沿所述灯杯的周向均匀 分布。
较佳地， 在本发明的各实施例中， 多个所述出气口沿所述灯杯的周向均匀 分布。
较佳地， 在本发明的各实施例中， 多个所述引导通路在所述灯杯的内壁上 沿周向均匀分布。 也就是说， 引导通路本身沿灯杯内壁沿从进气口到出气口的 方向延伸， 不过各弓 ]导通路之间沿周向均匀地相互分开。
较佳地， 在本发明的各实施例中， 多个所述通气孔在所述光源支架的周边 区域沿周向均匀分布。 较佳地， 在本发明的各实施例中， 所述进气口的直径为 3.5 - 4.5mm, 优选 地为 4mm。
较佳地， 在本发明的各实施例中， 所述出气口的直径为 1.5 - 2.5mm, 优选 地为 2mm。
应理解， 为了增强排气散热效果， 出气口的尺寸可大于进气口的尺寸。 在 一个实施例中， 灯杯的下开口大于上开口， 在下方的出气口多于在上方的进气 口， 数量较少的出气口在尺寸上大于数量较多的进气口。
较佳地，在本发明的各实施例中，所述引导通道的周向宽度为 2.5 - 3.5mm, 优选地为 3mm。在引导通道在灯杯内壁上的相邻凸棱之间形成时，所述周向宽 度为相邻凸棱之间的间距； 在引导通道由灯杯内壁上的凹槽直接形成时， 所述 周向宽度为 槽的宽度。
较佳地， 在本发明的各实施例中， 所述通气孔的直径为 3.5 - 4.5mm, 优选 地为 4mm。
应理解， 在本发明的各实施例中， 灯杯（及其上下开口）和灯盖可以具有 圓形的形状， 玻璃照明灯的轴向可为对称轴方向， 在这种情况下， 光源支架可 以是圓形的光源支板且其外边缘轮廓与灯杯内壁轮廓对应。 不过， 根据需要， 灯杯（及其上下开口）和灯盖也可为非圓形的形状， 例如正方形或正六边形的 形状或其它非规则形状。
在本发明各实施例中所述的具有散热功能的玻璃照明灯中， 一些重要部件 (例如灯杯或灯盖）可通过玻璃制成。 不过应理解， 不必要采用玻璃制成所述 玻璃照明灯中的所有部件。
较佳地， 在本发明的各实施例中， 所述灯杯通过玻璃制成。
较佳地， 在本发明的各实施例中， 所述灯盖通过玻璃制成。
这样， 能够通过玻璃材料制成玻璃照明灯的部件（例如灯杯和灯盖）， 在 实现如前所述的高效散热效果的同时， 一方面降低了材料成本和加工难度， 从 而使玻璃照明灯的制造成本降低； 另一方面使玻璃照明灯不仅具有良好的照明 性能（例如通过采用玻璃灯盖而提高照明质量）， 而且具有更好的耐高温性能 (优于塑料部件）。 此外， 由于采用可再循环的玻璃为原料制造其部件， 因而 与传统上采用金属材料或塑料材料相比， 在制造过程中不会或很少产生废料 (例如废水或废气）， 不会污染环境， 因而还具有显著的环保意义。
较佳地， 在本发明的各实施例中， 所述玻璃照明灯是 LED灯或金卤灯或 通用射灯。 在优选实施例中， 所述玻璃照明灯是 LED灯， 则所述光源是 LED 光源， 且更优选地多个 LED光源以阵列布置共同发光。
通过本发明的实施例提供的玻璃照明灯， 能够实现良好散热性。
本发明提供的各种实施例可根据需要以任意方式相互组合， 通过这种组合 得到的技术方案， 也在本发明的范围内。
显然， 在不脱离本发明的精神和范围的情况下， 本领域技术人员可以对本 发明进行各种改动和变型。 这样， 如果对本发明的这些改的和变型属于本发明 权利要求及其等同方案的范围之内， 则本发明也将包含这些改动和变型。
