Description

LED灯具的改良结构 技术领域
本发明涉及一种LED灯具的改良结构。
背景技术
有一种灯具结构，是将发光体安装在反光杯的内侧底部，如图1所示，当灯亮起时，发光体发出的光大部分直接从灯具内射出，只有侧边的小部分光通过反光杯反射之后再射出灯具之外。这种结构的灯具由于发光体发出的光直射出来，当人的眼睛正对灯具时，很容易被光线直射，而给人以刺眼的感觉。对于有些大功率的LED发光体来说，光线很强烈，直射眼睛还会有刺痛的感觉。
为此，出现了一种改进的灯具结构，如图2所示，该灯具将发光体设置在一个从反光杯底部伸出的垂直柱体的侧面，这样发光体发出的光将直射在反光杯上，再由反光杯反射出灯具。这种灯具结构由于发光体的主要发光区域并不直接射出灯具之外，因此可以解决刺眼的问题，但是却有一部分光线被柱体遮挡，因此该灯具的光强较弱，通常会在灯具的照射区域中心形成暗区，而影响照明效果。
发明内容
本发明所要解决的技术问题在于提供一种LED灯具的改良结构，其不但可避免光线直射眼睛而产生刺眼的感觉，而且还可使光强均匀不产生暗区。
为解决上述技术问题，本发明的技术解决方案是：
一种LED灯具的改良结构，该灯具在其灯体的外侧设置有反光杯，该反光杯的底部设有向外延伸的固定座，该固定座上设有斜面，该斜面相对灯具轴线的夹角大于0度小于90度，斜面上安装有至少一个发光体。
所述固定座上的斜面设置有多个，且多个斜面绕灯具轴线均匀公布，每个斜面上均安装有至少一个发光体。
所述固定座下主设置有一帽盖。
所述反光杯的反光面成由若干小块的棱面组成。
采用上述方案后，由于本发明所述的灯具将发光体安装在与灯具轴线具有一夹角的斜面上，而不是象现有技术那样将发光体安装反光杯的底部朝向灯具的外侧，这样在灯亮起时，发光体发出的大部分光线将射向反光杯，再由反光杯反射后从灯具射出，因为光线不是垂直射出，所以没有直射形的灯那么不刺眼，而发光体也不是设置在竖直面上的，因此也不存在光线被遮挡的问题，不会形成暗区。
另外，本发明可以设置多个均匀公布的斜面，使发光体均匀公布，这样反射出来的光线更为均匀更为柔和。
附图说明
图1是现有一种灯具的发光光线示意图；
图2是现有另一种灯具的发光光线示意图；
图3是本发明第一实施例的立体示意图；
图4是本发明第一实施例的剖视示意图；
图5是本发明第一实施例反光杯及LED固定座的立体示意图；
图6是本发明发光体发光光线示意图；
图7是本发明第二实施例的剖视图；
图8是本发明第二实施例的立体分解图；
图9是本发明第三实施例的剖视图。
具体实施方式
下面结合附图和具体实施例对本发明作进一步详述。
本发明所揭示的是一种LED灯具，如图3、4、5所示，为本发明的较佳实施例。所述LED灯具在其灯体1的外侧设置有反光杯2，该反光杯2的底部设有向外延伸的固定座3，该固定座3上设有斜面31，该斜面31相对灯具轴线的夹角大于0度小于90度，斜面31上安装有至少一个LED4。
由于所述的灯具将LED4安装在与灯具轴线具有一夹角的斜面31上，这样在灯亮起时，LED4发出的大部分光线将射向反光杯2，再由反光杯2反射后从灯具射出，如图6所示。因为光线不是垂直射出，所以没有直射形的灯那么不刺眼，此外LED也不是设置在竖直面上的，因此也不存在光线被遮挡的问题，不会形成暗区。
更进一步的，为了使光线更为均匀，所述固定座3上的斜面31可以设置多个，且多个斜面绕灯具轴线均匀公布。例如本实施例设置有三个均匀公布的斜面31，每个斜面31上均安装有至少一个LED4，这样反射出来的光线更为均匀更为柔和。
另外，所述的反光杯2的反光面可以设置成由若干小块的棱面21组成，将整块较大的反光面打碎成小块的棱面之后，通过减少每块反光面的面积，可以避免形成大块的反射光斑，使形成的光线更为柔和舒适。
需要说明的是，所述的斜面31与灯具轴线的夹角虽然理论上只需大于0度小于90度，但是实际上，其角度越小，所向外直射的光线也越小，效果就越好。如图7、8所示，本实施例所述的固定座3上设有三个斜面31，该斜面31与灯具轴线的夹角为15度。如图9所示，该实施例所述固定座3上的斜面31相对灯具轴线的夹角为5度。图7、8、9所示实施例的其它结构及标号均与第一实施例相同。
再者，继续配合图7、8、9所示，本发明还可以在所述固定座3的下方设置一个帽盖5，用以遮挡LED4，可以进一步避免光线直射而导致的刺眼问题。
