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
发光二极管光源作为一种新兴的第三代光源，虽然现在还不能大规模取代传统的白炽灯，但是其具有工作寿命长、节能、环保等优点，而普遍被市场看好。而且，目前由发光二极管组成的模块能产生大功率、高亮度的光源，因此将广泛地、革命性地取代传统的白炽灯等现有的光源，进而成为符合节能环保主题的主要光源。
目前，常用的发光二极管灯具一般是以恒定的功率提供照明灯光，无法根据具体场景的需要提供不同功率的照明灯光。因此，此类发光二极管灯具不仅造成不必要的使用浪费，同时，也难于满足使用者在不同情况下对不同照明强度的要求。
发明内容
有鉴于此，有必要提供一种可调节出光功率的发光二极管灯具。
一种发光二极管灯具，包括一灯体和安装于灯体内的若干发光二极管，还包括安装在灯体上的一控制开关，通过转动操作所述控制开关，可以对所述发光二极管模组进行I1、I2……In等n种导电连接方式连接，来实现n种不同功率的输出，其中发光二极管灯具处于Ix点连接状态时，具有Qx个发光二极管处于回路连接状态，此时光二极管灯具的输出功率为Wx；发光二极管灯具处于Iy点连接状态时，具有Qy个发光二极管处于回路状态，此时光二极管灯具的输出功率为Wy；当x＞y时，Qx＞Qy，Wx＞Wy；当x＜y时，Qx＜Qy，Wx＜Wy。
上述发光二极管灯具可以根据不同场景的具体需要，通过旋转操作控制开关，改变处于工作状态下的发光二极管数量，来提供不同功率不同强度的照明光线，从而既能满足各种各样的照明需求，同时也能避免不必要的浪费。
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为本发明发光二极管灯具的一优选实施例的立体示意图。
图2为图1中发光二极管灯具的电路示意图。
图3为本发明发光二极管灯具的另一优选实施例的立体示意图。
具体实施方式
请参阅图1，本发明一实施例中的发光二极管灯具用于为室内和户外一些特定的场合提供可调节光强的照明灯光，该发光二极管灯具包括一灯体10、安装在灯体10上的控制开关20、覆盖灯体10顶部的一透明灯罩30和安装在灯体10内并面向灯罩30的一发光二极管模组40
上述灯体10呈圆台状，其较小的一端形成一灯头12，该灯头12可适用目前长的标准白炽灯灯座，可以理解的是，该灯头12可以使其他类型或形状的连接结构，以适用不同的灯座。
上述灯罩30由灯体10顶端部的内侧向上拱起，以将发光二极管模组40罩设于灯体10内。
上述发光二极管模组40包括一圆形电路板42和安装在电路板42上的若干发光二极管44。该电路板42呈圆形，正好容置并固定在灯体10的上端部内。所述发光二极管44在本实施例中的数量为九个，均匀安装在电路板42朝向灯罩30的一侧，以便所述发光二极管44发出的灯光直接透过灯罩30照射出去。
上述控制开关20位于灯体10的上端缘处，其包括一固定部分22和一转动部分24。所述固定部分22呈圆环状，由灯体10的顶端周缘向外延伸。所述转动部分24也呈圆环状，可转动安装在灯体10的周面上并毗邻该固定部分22。
所述控制开关20通过所述转动部分24相对固定部份22转动，来改变发光二极管模组40的导电连接方式，从而改变发光二极管模组40发出灯光的强度。在不同的导电连接方式下，所述发光二极管模组40上处于工作状态的发光二极管44数量不同，而实现发光二极管灯具出光功率的不同。
请同时参阅图2，在本实施例中，该发光二极管灯具具有I、II、III等三种导电连接模式，所述固定部分22与供应电源的负极连接，所述I、II、III分别对应发光二极管44串联电路上的不同点位，且所述I、II、III的导电接入点分别设置于固定部分22上。当控制开关20的转动部分24转到其上的箭头正对I时，图2中开关与I点连接，其中有三个发光二极管44处于回路状态，而其他六个发光二极管处于开路状态；当控制开关20的转动部分24转到固定部分22上的箭头正对II时，图2中开关与II点连接，其中有六个发光二极管44处于回路状态，而其他三个发光二极管处于开路状态；当控制开关20的转动部分24转到固定部分22上的箭头正对III时，图2中开关与III点连接，所有发光二极管44均处于回路状态，此时，发光二极管灯具的出光功率达到最大。
如图3所示，本发明另一种实施方式的发光二极管灯具，该发光二极管灯具的控制开关50，可以通过连接I1、I2……In等n种导电连接方式，来实现n种不同功率的输出。当发光二极管灯具处于Ix点连接状态时，发光二极管模组60上具有Qx个发光二极管64处于回路状态，既是，此时的光二极管灯具有Qx个发光二极管64发光，其他处于熄灭状态，此时光二极管灯具的输出功率为Wx；当发光二极管灯具处于Iy点连接状态时，发光二极管模组60上具有Qy个发光二极管64处于回路状态，此时光二极管灯具的输出功率为Wy；当x＞y时，Qx＞Qy，Wx＞Wy；当x＜y时，Qx＜Qy，Wx＜Wy。
由此可见，上述发光二极管灯具可以根据不同场景的具体需要，通过旋转操作控制开关，改变处于工作状态下的发光二极管数量，来提供不同功率不同强度的照明光线，从而既能满足各种各样的照明需求，同时也能避免不必要的浪费。
