本申请涉及照明领域， 尤其涉及一种 LED灯具。
背景技术
现有的 LED灯具， 如图 1所示， 包括： 基板 11、 散热器 12, LED灯 带 14。 其中， LED灯带 14 ( 0点的位置）置于基板上。 而对于 LED灯带 14的排放是随基板 11 ( C点到 D点之间的位置 )延伸结构进行顺序排放， 就形成了 LED灯带 14置于 180度平面排放， 那么所释放的光角最大形成 180度。 显然， LED灯带 14发光范围受 LED灯管的平面设计限止而局限 了发光面积。
并且， 现有技术的设置还无法避免因 LED灯带直射而产生的眩光。 那 么为了避免眩光产生， 还会在 LED灯带上置相应的灯罩 13。但是， 灯罩确 也是直接影响 LED灯带发光效果的。 发明内容

为使本申请的目的、 技术方案和优点更加清楚， 以下结合附图及具体 实施例， 对本申请作进一步地详细说明。
实施例一：
如图 2-7所示， 根据本申请的实施例， 提供了一种 LED灯具， 包括： LED灯壳 25、 LED灯管和反射器 21。
LED灯管
如图 2-7所示， 所述 LED灯管， 进一步包括： 由 CO和 DO所表示的 基板 22、 由 A点与 B点所表示的 LED灯带 23 , 所述基板 22沿所述 LED 灯管的延伸方向具有一延伸结构 （即， 图 3中 COD延反射器 21的延伸方 向的部分） ， 所述延伸结构具有截面呈三角形或 V型的凸起（点 COD所 示的部分） ， 所述延伸结构的底面具有一平面结构， 所述 LED灯带 23贴 合于所述凸起两侧的斜面上（即， CO所示出的斜面和 DO所示出的斜面） 从而形成两个出光面，所述两个出光面组合所构成的出光角大于 180度（优 角 COD ) 。 如图 2-7所示为解决只局限于平面式光线射出的范围的局限， 使其可以实现多角度发光调节。 对基板 22沿 LED灯管的延伸方向的延伸 结构进行改进。
图 2-7所示， 在所述基板 22沿所述 LED灯管的延伸方向具有一延伸 结构， 对所述延伸结构具有截面呈三角形或 V型的凸起的设置 （由 COD, 以 0为中间轴线的延伸方向），并且所述延伸结构的底面具有一平面结构。 此处的设计可以有效地解决 LED 灯管中只局限于平面投影映射光线的范 围。 其次， 所述 LED灯带 23贴合于所述凸起两侧的斜面上从而形成两个 出光面（即 CO所处的斜面与 DO所处的斜面）； 即， LED灯带 23的排放 并没有局限于在基板 22平面上排放， 而是排放于截面呈三角形或 V型的 凸起的两侧， 即 CO所处的斜面与 DO所处的斜面， 这样就会形成两个出 光面， 且所述两个出光面具有一夹角， 所述夹角为所述三角形或 V型的顶 所述优角大于 180度， 覆盖面积更大。
反射器 21
本申请中对反射器 21的安装有效地避免了图 1中现有技术所出现的眩 光及 LED灯带输出光的发光率不均勾等问题， 并且也是本申请的核心。 图 2-7所示， 反射器 21沿所述 LED灯管的延伸方向具有一延伸结构， 所述延 伸结构的横截面为两个并排相连的穹顶 （即反射器的凸起部分） ， 所述穹 顶的底端具有开口。 并且所述穹顶的开口朝向所述出光面， 每个出光面分 别位于一个穹顶的包围中 （穹顶呈倒抛物面将出光面全部包括） ， 所述穹 顶的开口面积大于所述出光面面积； 每个出光面的光线射向相应的穹顶内 壁， 经所述穹顶内壁反射并由所述穹顶的开口中未被所述出光面遮挡的部 分射出。
LED灯壳 25
LED灯壳 25、 反射器 21和 LED灯管存在两种连接关系：
1 )如图 2、 3和 4所示， 所述 LED灯壳 25由所述穹顶的背侧罩扣在 所述反射器 21上并卡合固定， 所述 LED灯壳 25的壁面由所述反穹顶的开 口的侧面伸出， 所述基板 22通过所述延伸结构的中心轴位置与所述 LED 灯壳伸出的壁面固定从而使所述基板绕所述中心轴转动固定， 并且所述穹 顶的开口朝向所述出光面， 所述基板 22的凸起（优选顶点位置）与所述反 射器 21的穹顶的相连端相对应并间隔一段距离， 具体来说， 是与所述基板 22的凸起的顶点位置（0点处） 间隔一段距离。 所述距离的设置与所述穹 顶的高度、 由所述穹顶的开口中未被所述出光面遮挡的部分的宽度、 基板 22的宽度（CD间的距离）有关， 一方面可以保证所述 LED灯管沿中心轴 转动从而可以将贴有 LED灯带 23的面转向下方便装卸 LED灯带 23 ,另一 方面可以保证 LED灯带 23的部分光线（射向 0点的光线）可以从所述距 离形成的开***向另一侧的反射器 21并经过 1-2次反射后由这一侧的穹顶 的开口中未被所述出光面遮挡的部分射出。
2 )如图 5、 6和 7所示， 所述 LED灯壳 25由所述穹顶的背侧罩扣在 所述反射器 21上并卡合固定， 所述 LED灯壳 25的壁面由所述反穹顶的开 口的侧面伸出， 所述基板 22与所述 LED灯壳伸出的壁面固定， 所述反射 器 21通过所述穹顶的相连端与所述基板的凸起（优选顶点位置）相连并且 所述穹顶的开口朝向所述出光面。这样就会形成 LED灯带的每个出光面都 分别位于一个穹顶的包围中，并且穹顶的开口面积大于 LED灯带的出面面 积。 当出光面的光线射向相应的穹顶内壁时， 光线会由穹顶的开口中未被 所述出光面遮挡的部分射出。 即， 形成两个出光面， 分别通过设置两个出 光面所对应的反射器 21 , 来对 LED灯带 23发光效果的调节与分配。
所述 LED灯带 23射出的光线经过反射器 21的反射后向下方射出， 所 述反射起到了柔光效果， 可以有效避免眩光， 还可以获得更加均匀的出光。 图 2-7所示， 还包括： 由 CED所示的散热型材 24, 安装在所述延伸结 构的底面（CD示为基板底面）， 所述散热型材 24的外形与所述 LED灯管 的轮廓相适应。 再由， 图 2-7 中所示的由所述延伸结构具有截面呈三角形 或 V型的凸起结构，其所述凸起具有中空式结构从而形成一通风散热通道； 由所述散热型材 24结合延伸结构与截面自然成形的通风散热通道，有效地 实现了双向散热的方式， 以达到 LED灯使用寿命。
本申请所提出的一种 LED灯具， 为使 LED灯带产生最佳发光效果， 优选地， 所述 LED灯带 23在所述延伸结构两侧的斜面上沿所述灯具的延 伸方向排列， 所述 LED灯带 23设置在所述斜面沿所述灯具的延伸方向的 中轴线上。 但是， 对于 LED灯带 23的排列， 本申请并不限于此。
实施例二：
如图 8-13所示， 本申请提出另一种 LED灯具， 包括： LED灯壳 45、 LED灯管和反射器 41。
LED灯管
所述 LED灯管， 进一步包括： 基板 42 ( C与 D之间的位置）和 LED 灯带 43 (八与8的位置） ， 所述基板 42具有一平面结构， 所述 LED灯带 43 固定在所述基板 42沿所述灯具的延伸方向的中轴线的两侧从而形成两 个出光面（CO与 DO构成两个出光面）。 由于现有的 LED灯管的 LED灯 带都是直接垂直于基板平面上安装， 为了节约资源并且可以最好地利用 LED灯带发光效果， 将 LED灯带设置在两个出光面上， 即 LED灯带固定 在所述基板沿所述灯具的延伸方向的中轴线的两侧从而形成两个出光面。
反射器 41
本申请中对反射器 41的安装有效地避免了图 1中现有技术所出现的眩 光及 LED灯带输出光的发光率不均勾等问题， 并且也是本申请的核心。 如 图 8-13所示，所述反射器 41沿所述 LED灯管的延伸方向具有一延伸结构， 所述延伸结构的横截面为两个并排相连的穹顶 （即反射器的凸起部分） ， 所述穹顶的底端具有开口。 并且所述穹顶的开口朝向所述出光面， 每个出 光面分别位于一个穹顶的包围中 （穹顶呈倒抛物面将出光面全部包括） ， 所述穹顶的开口面积大于所述出光面面积（即， CO与 DO的出光面面积小 于反射器 41所构成的倒抛物面）；每个出光面的光线射向相应的穹顶内壁， 经所述穹顶内壁反射并由所述穹顶的开口中未被所述出光面遮挡的部分射 出。 以此， 避免由 LED灯带强光所产生直射时造成的眩光情况。
LED灯壳 45
LED灯壳 45、 反射器 41和 LED灯管存在两种连接关系：
1 )如图 8-10所示， 所述 LED灯壳 45由所述穹顶的背侧罩扣在所述 反射器 41上并卡合固定， 所述 LED灯壳 45的壁面由所述穹顶的开口的侧 面伸出， 所述基板 42通过所述延伸结构的中心轴位置与所述 LED灯壳 45 伸出的壁面固定从而使所述基板绕所述中心轴转动固定， 并且所述穹顶的 开口朝向所述出光面， 所述基板 42与所述反射器 41的穹顶的相连端相对 并间隔一段距离， 具体来说， 所述反射器 41的穹顶的相连端是与所述基板 42的中轴线位置（0点处）对应并间隔一段距离。 所述距离的设置与所述 穹顶的高度、 由所述穹顶的开口中未被所述出光面遮挡的部分的宽度、 基 板 42的宽度（CD间的距离 )有关， 一方面可以保证所述 LED灯管沿中心 轴转动从而可以将贴有 LED灯带 43的面转向下方便装卸 LED灯带 43 ,另 一方面可以保证 LED灯带 43射向 0点的光线可以从所述距离形成的开口 射向另一侧的发射器 41并经过 1-2次反射后由这一侧的穹顶的开口中未被 所述出光面遮挡的部分射出。
2 )如图 11-13所示， 所述 LED灯壳 45由所述穹顶的背侧罩扣在所述 反射器 41上并卡合固定， 所述 LED灯壳 45的壁面由所述穹顶的开口的侧 面伸出，所述基板 42与所述 LED灯壳 45伸出的壁面固定， 所述反射器 41 通过所述穹顶的相连端与所述基板 42相连，并且所述穹顶的开口朝向所述 出光面； 本实施例中， 对于反射器 41的设置^^于所述基板 42呈垂直平 面安装。 例如， LED灯带 43位于基板中轴线的两侧排放（以 0点为中心 点两侧排放 LED灯带）， 反射器 41通过穹顶的相连端与所述基板 42相连 并与基板的中轴线位置固定； 由于设置的穹顶的开口朝向 LED灯带 43的 出光面， 所以， 每个 LED灯带 43出光面都被所在穹顶面给包围 （即， CO 与 DO的出光面面积小于反射器 41所构成的倒抛物面）。 由于所述穹顶的 开口面积大于所述出光面面积； 每个出光面的光线射向相应的穹顶内壁， 经所述穹顶内壁反射并由所述穹顶的开口中未被所述出光面遮挡的部分射 出。
基于对上述反射器的设置，有效地避免了 LED灯带直射所产生的眩光。 现光效利用输出最佳效果。 并且， 无须现有技术中由灯罩对 LED灯带光效 进行控制。 对于上述 LED灯带的排列， 优选地， 所述 LED灯带 43在所述 中轴线的两侧沿所述灯具的延伸方向排列。 可以有效地实现光效最大化。
进一步地， 还包括： 由 CED面所示的散热型材 44, 安装在所述基板 42上远离所述出光面的一面， 所述散热型材 44的***轮廓与所述 LED灯 管的轮廓相适。
另外， 对于上述实施例一和实施例二， 反射器的穹顶开口的伸出端的 长度设置的要求如下： 所述每个出光面的最外侧的出光光路与所在出光面 的法线所形成的夹角， 小于等于， 所述每个出光面上所述 LED灯带的侧向 线与所在出光面的法线所形成的夹角， 其中， 所述每个出光面上所述 LED 灯带的侧向线为所述每个出光面上所述 LED灯带与相应穹顶开口的伸出端 点的连线。
具体来说， 参见图 14-17, 设置在基板 OD面上的 LED灯带 43 ( B的 位置）， 其光线出射的角度区间为 ΥΒΖ' , 其中， BY为最内侧的出光光路， BZ'为最外侧的出光光路， BY和 BZ'相对于垂直于 B点的法线（法线如图 14-17中的虚线所示）对称， 其中最外侧的出光光路 BZ'与法线形成的角度 为 α' , 同时 Β点与穹顶开口的伸出端点 Ζ的连线为 BZ, BZ与法线形成的 角度为 α, 当 α'小于等于 α时， 即穹顶开口的伸出端点 Ζ向下方伸出的深 度超过 Ζ' , 可以使得 LED灯带 43 ( B的位置） 的全部直接出光的光路均 要经过反射器 41的反射， 而不会有部分直接出光的光线未被反射器 41拦 截从而漏出， 这样可以保证 LED灯带 43 ( B的位置）的全部直接出光光线 均经过了反射器 41 的反射柔光， 而不会有直接出光的光线漏出以发生眩 光。
而设置在基板 OC面上的 LED灯带 43 ( A的位置）与设置在基板 OD 面上的 LED灯带 43 ( B的位置）完全对称， 穹顶开口的伸出端点 Z向下方 伸出的深度也要超过 Ζ' , 因此不再赘述。
此外，对于上述实施例一和实施例二中， 所述反射器 41的穹顶的相连 端是与所述基板 42的中轴线位置 （0点处）对应并间隔一段距离的情况， LED灯带的最内侧的出光光路可以通过所述间隔的距离射向另一侧的 LED 灯带所在反射器的穹顶内壁，经反射后由所述另一侧的 LED灯带的穹顶的 开口中未被出光面遮挡的部分射出，从而对另一侧的 LED灯带的穹顶的开 口的射出光线的照度进行补偿。
具体来说， 参考图 2、 14和 8、 16, 由于所述反射器 41的穹顶的相连 端是与所述基板 42的中轴线位置（0点处）对应并间隔一段距离， B位置 的 LED灯带 43的最内侧的出光光路 BY可以通过间隔的距离射向 A位置 的 LED灯带 43所在反射器 41的穹顶内壁，经反射后由所述 A位置的穹顶 的开口中未被出光面遮挡的部分射出， 从而对 A位置的穹顶的开口的射出 光线的照度进行补偿； 同样， A位置的的 LED灯带 43的最内侧的出光光 路也可以通过同样的方式射向 B位置的 LED灯带 43所在反射器 41的穹顶 内壁，经反射后由所述 B位置的穹顶的开口中未被出光面遮挡的部分射出， 从而对 B位置的穹顶的开口的射出光线的照度进行补偿。
以上所述仅为本申请的实施例而已， 并不用于限制本申请， 对于本领 域的技术人员来说， 本申请可以有各种更改和变化。 凡在本申请的精神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本申请的权 利要求范围之内。
