Description

对流换热音响灯具 技术领域
本发明涉及一种照明装置，尤其涉及一种对流换热音响灯具。
背景技术
目前市售的发光组件多种多样，其中，发光二极管（LED）因体积小、使用寿命长以及省电等优点，深受用户青睐并且已广泛应用于各种不同的用途。
为了增加发光二极管与照明灯具的应用性，在发光过程中，如何散热以避免发光二极管烧毁一直是发光二极管的发展重点之一。传统的发光二极管灯具的散热方法是将发光二极管热能传导或者辐射至周围空气中，然而，散热元件周围的空气若缺乏流动性，将影响发光二极管的散热效果。因此，传统的发光二极管灯具仍有很大改进空间。同时，传统的发光二极管灯具仅限于照明的单一用途，因此，整合其他功能与发光二极管灯具中亦可为发光二极管灯具的发展方向之一。
目前最常见的散热方式是为LED灯板加入金属材料散热器，通常根据LED灯具的外形设计散热器的形状，金属材料一般使用铝合金。LED灯板产生的热量经金属材料散热器导出后再散发到外部空间，通常是利用自然传导、辐射和自然对流散热三种形式，有时还加上小风扇利用强制对流进行散热。
虽然上述措施实施起到了一定的散热作用，但散热的效果并不理想，因此需要寻找更好的散热方式。同时根据市场需要，如何将适当的其他功能整合于发光二极管灯具，并增加发光二极管灯具的散热效果，也是目前急需努力的目标。
发明内容

图1示出了本发明第一实施例中的对流换热音响灯具，该对流换热音响灯具包括外壳1、扬声器3、电路板、发光组件2、安装座6、散热件4以及散热腔道7，通过将扬声器3和发光组件2合二为一，一方面方便声音的布局，另一方面具备照明的作用。
该外壳1包括第一外壳18与第二外壳17，该第一外壳18的一端设置有一个开口11，该开口11的相对的另一端设有灯头12。该灯头12为电源接头，主要用于将灯具连接到灯座上，接入电源。可以理解地，该外壳1的形状可以根据需要做成各种形状，例如圆柱形、方形等；为了更好的散发灯具的热量，该外壳1可以采用良导热材质做成，例如铝外壳、铜外壳等各种金属制成的外壳。
进一步地，该外壳的侧壁还可以设置有散热结构，例如，在外壳1的内壁和/或外壁制作散热筋等增大散热面积的结构。
一同参阅图2、图3，该开口11位置处安装有安装座6，该安装座6的形状与外壳1的开口11形状相适配。可以理解地，该安装座6可以为与外壳1相互独立的两个构件，通过紧固机构紧固连接（如螺接、卡扣、铆接、焊接等）；安装座6和外壳1也可以是一整体构件，通过一体成型的方式形成。
在该安装座6中部上设置有一个安装位及设置在安装位外围的间隔分布分第二通道61，扬声器3封闭连接在该安装座6的安装位内，并通过安装座6封闭安装在外壳1的开口11处，将整个灯具分隔出两个相互隔离的腔室，即外壳1的内侧形成内腔14、外侧形成外腔15。可以理解地，扬声器3的安装可以采用现有的各种安装方式，例如采用螺接、焊接及卡扣等方式固定安装。
可理解地，该扬声器3也可为通过其他方式连接在外壳1的开口11处，例如直接连接，具体为在扬声器3上一体设置与外壳1的开口11相对应的封闭、支撑装置，然后直接将扬声器3封闭安装于外壳1开口11处即可。
在扬声器3安装后，外壳1与扬声器3的下部形成内腔14，利于扬声器3的发声，具有使扬声器3放大声音、加强原声的作用。
该扬声器3的上方设置有发光组件2及散热件4，其中散热件4与该扬声器3正对，而发光组件2设置在散热件4的外围。
该发光组件2可安装在安装座6上，其可包括LED灯板22以及透光件21。透光件21设置在LED灯板22的上方，可以根据需要使得LED灯板22出光更加均匀或改变光线的方向等。
本实施例中，该LED灯板22呈圆环形，并环绕扬声器3布置在扬声器3外围的安装座6上，与之相对应的透光件21为圆环状，该圆环状透光件21有一定高度。透光件21的内壁与外壁之间设置有用于容纳LED灯板22的容置部23，该容置部23主要起容纳、保护LED灯板22的作用，并且适当的减小了灯具的体积，该容置部23与外腔15连通。
可理解地，该LED灯板22也可为其他形式安装，例如，直接在壳体内设置用于安装LED灯板22的支架，将LED灯板22直接安装于外壳1内。
一同参阅图1、图2及图3，散热件4的形状为圆柱体状，该散热件4与扬声器3正对，并且散热件4与发光组件2导热连接，以便于快速地将发光组件2产生的热量导出。圆柱体状散热件4的直径与圆环状透光件21内径相适配，以便散热件4能够纵向插接在透光件21内，并且散热件4的高度与透光件21的高度相当。该散热件4主要起到散热作用，并且在散热件4上设置有散热孔41，该散热孔41沿散热件4的轴线方向设置。散热孔41连通至外腔15，使得外腔15与外界联通起来，从而在扬声器3工作时，扬声器3的膜片32产生震动，在膜片32凸起时，将扬声器3外腔15中的空气及LED灯板22周围的热空气，通过散热件4上的散热孔41排出；在膜片32凹进时，将扬声器3外腔15的外部的冷空气通过散热件4上的散热孔41吸入，形成强制的空气流动，可以加快散热件4的表面换热，提高散热效率。当然，散热件4还可为与透光件21适配的其他形状。
该散热腔道7包括第一腔道16以及第二腔道61；该第一通道16连通内腔14，第二通道61为间隔地设置在安装座6上。该第一通道16与第二通道61连通，该第二通道61另一端又连通容置部23，该容置部23有进一步连通外腔15。
本实施例中，该第二外壳17安装在第一外壳18的内侧，此处所说的安装可为第二外壳17一体成型设置在安装座6上，或者为固定安装在安装座6上，第一外壳18及第二外壳17之间的间隙即为第一通道16，并且第二外壳17的下端与第一外壳18内壁之间设有间隙。
当然，在其他一些实施例中，散热腔道7也可为其他结构，例如依附在第一外壳18内壁上的管件，该管件上端连通第二通道61，下端连通内腔14。当然，在其他一些实施例中，第二外壳17也可通过其他方式安装在第一外壳内18部，并与第一外壳18形成第一通道，例如，第二外壳17外壁上间隔设置支撑柱，然后通过该支撑柱固定连接到第一外壳18内壁面上。
在该灯具使用时，内腔14中的热气流会流经第一通道16、第二通道61、容置部23、外腔15及散热件41，此时若扬声器的膜片32凸出，热气流会流经散热孔41排出，带走内腔14、散热通道7及LED灯板22周围的热量，同时内腔14中的部分热气流还可通过透气孔13排出；此后扬声器的膜片32凹进，外界的冷气流流经散热孔41、外腔15、容置部32、第二通道61及第一通道16后会进入内腔14，冷气流对LED灯板22、第一、二通道壁面及内腔14进行冷热空气交换，进而起到冷却作用。在灯具使用时，该散热腔道7结合透气孔13交换气流，大大增加了灯具的散热效果。
该外壳1内还安装有电路板，为发光组件2和扬声器3提供工作电源以及控制信号。在本实施例中，该电路板包括与控制LED灯板22连接的第一电路板221、以及与控制扬声器3连接的第二电路板31。可以理解地，该第一电路板221、第二电路板31可以通过现有的各种固定方式固定，例如螺钉、卡扣等。
该第一电路板221与LED灯板22导电连接，为LED灯板22供电，并可输出控制信号，对LED灯板22的开关、色彩等进行控制。
该第二电路板31与扬声器3导电连接，用于为扬声器3供电及控制开关等，本实施例中，该第二电路板31位于扬声器3的下方、并位于第一电路板221上方。
可理解地，在其他一些实施例中，该电路板还可为一块，该一块电路板同时控制LED灯板22及扬声器3。
进一步地，在外壳1靠近灯头的位置处还设有透气孔13，通过该透气孔13将内腔14连通至外界，从而将内腔14内的热空气，通过透气孔13向外界排出散热。特别地，当扬声器3工作时，会产生空气振动，可将内腔14内的热空气强制从透气孔13中排出，以提高散热效率。
进一步地，在透气孔13相对应的外壳1的内部设置有防尘网5。该防尘网5主要用于防止外部的尘埃进入内腔14，以防止外界灰尘对灯具内的电路板、扬声器3等造成不利的影响。
图4、图5所示为该对流换热音响灯具的第二优选实施，在该第二实施例中，该灯具包括外壳1、扬声器3、电路板、发光组件2、安装座6及散热件4，本实施例中，该外壳1包括第一外壳18与第二外壳17，该第一外壳18采用了更为美观的中间小、两头大的结构，但其材质及功能与第一实施例基本相同，第二外壳17设置在第一外壳18内。
该第二实施例中，该散热件4为一体成型于安装座6上，散热件4的散热孔41穿透散热件4及安装座6，在散热件4正对的安装座6的另一面设置有安装位，扬声器3安装在安装位中，并且带有膜片32的面正对散热件4；在散热件4与扬声器3的膜片32之间为外腔15，散热件4上设置的散热孔41将外腔15与外界连通。
在第二实施例中，该透光件21包括壳体，该壳体为采用透光材料制作的壳体，壳体罩在LED灯板22上，与安装座6形成容置部23，该壳体通过底部设置的螺纹连接在安装座6上，并且安装座6上设置有连通容置部23与外腔15的小孔62；LED灯板22固定则可通过在固定座上设置卡槽等结构，将LED灯板22进行固定连接，当然，还可有其他方式来固定连接此LED灯板22。在壳体上还设置有通孔，通孔的形状与散热件4的形状相适配，并且散热件4穿过该通孔将外腔15与外界进行连通，为了使灯具可效散热且又能进行实时保护，在该通孔上还设置了防护盖211，该防护盖211上设置了孔。可以理解地，壳体也可通过其他方式连接到安装座6上，例如卡扣，螺接或者焊接等。
本第二实施例的其他组成元件的材质、各部件的组合、作用及带来的效果等，与第一实施例基本相同，此处不再赘述。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。
