Description

发光二极管灯具
技术领域
本发明涉及一种照明装置，特别涉及一种发光二极管灯具。
背景技术
相比于传统的发光源，发光二极管具有重量轻、体积小、污染低、寿命长高等优点，其作为一种新型的发光源，已经被越来越多地应用到各领域当中，如路灯、交通灯、信号灯、射灯及装饰灯等等。
在一些专业用途如作为户内外照明设备时，发光二极管模组在工作时会产生大量的热量，如若这些热量不能得到及时地散发，将容易导致发光二极管过热，使其发光效率降低，甚至于直接烧坏而无法继续工作。现有的发光二极管灯具往往通过在照明设备内设置与发光二极管模组相固定接触的散热器以对发光二极管模组进行散热。然而，此类散热器通常以锁螺钉的方式固定安装于到发光二极管灯具上，当需要更换散热器，或者发光二极管模组与散热器一体更换时，需要使用相关的专业工具拆卸、安装散热器，更换流程较复杂。
发明内容
有鉴于此，有必要提供一种方便安装、拆卸散热器的发光二极管灯具。
一种发光二极管灯具，包括一座体、一散热器和贴设于散热器上的若干发光二极管模组及若干固定所述散热器的扣具，所述散热器包括一基板及由基板底面向下延伸的若干散热鳍片，所述座体内具有一隔板，所述散热器的基板卡置在隔板上而散热鳍片向下穿过隔板，所述扣具横跨所述散热器基板将该散热器固定于座体上，而扣具中部抵压在所述基板上，所述扣具由一弹性金属线体连续弯折而成，其包括一枢接固定于所述隔板上的卡持部、分别由该卡持部两端延伸而出并抵压在基板上的二夹持部及分别由二夹持部的自由端向外延伸出并活动连接到所述隔板上的二插入部，所述每一夹持部包括间隔交替设立的二平直压制段及二n形把持段，所述扣具的插入部通过操作二夹持部的把持段发生弹性形变靠紧或回复原状从而活动连接到隔板上。
与现有技术相比，本发明发光二极管灯具通过若干扣具将所述散热器与座体相固定安装，拆卸及安装该散热器只需手动操作所述扣具即可，不需使用相关工具，方便安装、拆卸，从而简化了更换流程，提高了工作效率。
下面参照附图，结合实施例对本发明作进一步的描述。
