Description

灯具
技术领域
本发明涉及一种照明装置。
背景技术
一些特定灯具，诸如洗墙灯、隧道灯、景观性投射灯等，通常需要多个方向的照明，但现有技术下的单盏灯具的光源通常只能朝一个方向发光，为满足不同方向发光的照明需要，就必须同时使用多盏这样的灯具。
发明内容
有鉴于此，有必要提供一种单盏可同时满足不同方向照射的灯具。
一种灯具，包括一主体及位于主体相对侧的第一发光体和第二发光体，第一发光体、第二发光体与本体之间均呈一夹角，以使第一发光体和第二发光体发出的光在本体前方交汇。
与现有技术相比，本发明的二发光体位于单盏灯具两侧，且与灯具的本体之间均呈一夹角，使二发光体发出的光可在灯具前方交汇，从而使单盏灯具可以同时满足不同方向的照明要求，适宜应用在洗墙灯，隧道灯，景观性投射灯等照明场合。
下面参照附图，结合具体实施例对本发明作进一步的描述。
附图说明
图1是本发明一些实施例中灯具的立体组装图。
图2是图1中灯具的倒置图。
图3是图1中灯具的立体分解图。
图4是图1中灯具的出光示意图。
具体实施方式
本发明一些实施例中的灯具主要用作洗墙灯、隧道灯、景观性投射灯等。如图1至图4所示，本发明一些实施例的灯具大体上包括一主体1及位于主体1两相对侧的第一发光体2和第二发光体3，第一发光体2、第二发光体3与本体1之间均呈一夹角θ(如图4所示)，以使第一发光体2和第二发光体3发出的光在本体1前方交汇混合，该二夹角θ根据需要可以相等，也可以不相等，在一些实施例中，θ可为10～20度，优选地，可为15度，可以理解地，根据需要θ值也可以改变。
本体1包括一矩形盒状本体框体12。所述本体框体12底部具有一开口，一驱动电路组件80容置在本体框体12内，一盖板16罩设本体框体12的底部开口，以形成一密封的盒体，防止雨水、灰尘等物进入其中。本体框体12的一对纵长的侧壁上各开设有二固定孔120，以与螺钉(图未示)配合而将一支架20固定其上。本体框体12一较短的侧壁上安装有一防水接头18，用以供电线穿过与本体框体12内的驱动电路组件80相连。
所述第一、二发光体2，3均包括一矩形发光体框体14、一安装在发光体框体14底部的散热器30、一贴置于散热器30的发光二极管模组40、容置于发光体框体14内且罩设发光二极管模组40的一导光模组50、容置于发光体框体14内且罩设导光模组50的一导光罩60及抵压导光罩60的一按压件70。第一、二发光体2，3的发光体框体14自本体框体12顶部两相对侧朝相反方向斜向上延伸而出，每一发光体框体14包括一口字形基壁142及自基壁142外侧缘向上延伸出的三侧壁144，三侧壁144与本体框体12的纵长侧边围成一具有一定高度的容置空间，其中连接本体框体12的二侧壁144在临近本体框体12处各开设一漏水槽148，以便灯具在户外使用时积水可沿漏水槽148流出。基壁142的四角处开设四通孔146。
在一些实施例中，可以通过压铸等手段将上述本体框体12及由本体框体12顶部两相对侧朝相反方向斜向上延伸出的上述二发光体框体14一体成型，形成的一V形框体10。
每一支架20包括一连接件22及一支撑件24。连接件22为三角形金属片，其每一角的边缘处开设一通孔220，二螺钉穿过连接件22顶端的二通孔220螺锁固定于本体框体12侧壁的二固定孔120内。该连接件22中央开设一指示孔222。支撑件24由一金属板一体弯折而成，其包括一本体242及沿本体242一端垂直延伸出的一折边244。该折边244上开设二条形通孔248，用以供螺钉穿过将灯具固定在安装面(如地面)上。该本体242中央开设一枢接孔243，一铆钉穿过连接件22底端的一通孔220铆合固定于该枢接孔243内，从而将框体10与支架20枢接。与折边244相对的本体242另一端呈弧形，沿该弧形端缘设有一弧形滑孔246，当框体10相对于支架20的支撑件24转动时，连接件22的指示孔222可同时沿支撑件24的弧形滑孔246移动以指示框体10相对于支架20的支撑件24转动的角度。
每一散热器30由导热性能良好的材料一体制成，其包括一基呈矩形板32及从基板32底表面垂直向下延伸的若干散热片34。所述基板32顶表面间隔开设有若干安装孔(图未标)，以与螺钉配合而将发光二极管模组40固定其上，基板32四角处边缘各开设有一与框体10基壁142的通孔146对应的固定孔320。
每一发光二极管模组40包括若干平行排列的矩形电路板42及均匀固定于每一电路板42一侧面的发光二极管44。电路板42的另一侧面贴合于散热器30的基板32上。当然这些电路板42也可以由一整块电路板替代，这些发光二极管44则在电路板42上呈矩阵排列。所述电路板42开设有与基板32上安装孔对应的若干穿孔(图未标)。在一些实施例中，两个发光二极管模组40发出不同颜色的光a，b。由于本体框体12与发光体框体14之间存在夹角θ，使本体框体12左右两侧的发光二极管模组40发出的不同颜色的光a，b在本体框体12正前方交叉混合而生成第三种颜色的光，以适应一些特定场合的需求。
每一导光模组50包括一矩形固定架52及安装在固定架52上的若干透镜54。所述固定架52的尺寸略大于电路板42以完全覆盖对应的发光二极管模组40。固定架52对应电路板42上的发光二极管44处设有若干矩形的透孔520。所述透镜54对应安装在固定架52的透孔520处，发光二极管44发出的光经透镜54向外射出。固定架52底部的四角处一体凸伸出开设有通孔524的四定位柱522，定位柱522抵靠于发光体框体14的基壁142上。
每一导光罩60为一矩形平板，由透明或半透明材料如玻璃等制成。导光罩60的尺寸与发光体框体14尺寸对应，使其正好容置于发光体框体14内。该导光罩60的四角处设有对应于发光体框体14的通孔146的四孔洞600。该二导光罩60根据需要可以采用具有相同颜色的透明材料制成，也可以采用不同颜色的材料制成，使发光二极管44发出的光透过导光罩60后颜色发生改变。
所述呈矩形条状的按压件70用以按压于导光罩60的边缘处，其外围尺寸大小与导光罩60尺寸一致，以将导光罩60夹置于按压件70与导光模组50之间。按压件70的四角处设有对应于导光罩60的孔洞640的孔口700。
组装该灯具时，将发光二极管模组40贴设并固定于散热器30的基板32上；将导光模组50置于框体10的二发光体框体14内；再将导光罩60置于发光体框体14内使其抵压导光模组50；再将按压件70置于导光罩60上；再将散热器30置于发光体框体14底部；四螺钉顺次穿过按压件70的孔口700、导光罩60的孔洞600、导光模组50的定位柱522、发光体框体14的通孔146，并螺锁固定于散热器30的固定孔320内，从而将按压件70、导光罩60、导光模组50、框体10及散热器30固定在一起。
本发明的灯具使用时，由于本体框体12与发光体框体14间存在夹角θ，以使第一发光体2和第二发光体3发出的光在本体1前方交汇混合，特别地，在一些其他场合，可使置于发光体框体14内的二发光二极管模组40发出的不同颜色的光在本体框体12正前方发生混合而生成第三种颜色的光，从而使单盏灯具可以同时满足多种颜色光的照明要求。
