Description

智能灯光装置
技术领域
本发明为一种智能灯光装置， 详而言之为关于一种能因应既定范围内的环 境亮度而调整照明强度， 并兼具节省电力功能， 及使环境亮度有一致或有差别 性的设计。 背景技术
现有的灯体请参阅中国台湾专利公告号第 M418231号的省电灯具结构， 其 为一种省电灯具结构， 尤指一种可节省灯具多余的电流供应， 并能大幅减少电 力资源的支出及浪费的创新结构； 主要的一灯具为一中央处理器 (CPU)、 一光敏 电阻、 一红外线人体传感器所构成； 借此创新独特设计， 使本专利的灯具借由 光敏电阻及红外线人体传感器， 而可节省灯具多余的电流供应， 并能大幅减少 电力资源的支出及浪费， 进而使本专利能达到电力能源的节省的实用进步性。 然而， 该种习用的灯体虽可配合环境光线充足与否而自动调整光通量， 然 其采用的是以光敏电阻感应环境周遭光线强度， 但事实上， 光敏电阻仅会感受 环境光线亮度的差别， 但不能适当的被限制在感应既定范围内， 特别是室内通 常会安装多个灯体， 而仅有人为活动的区域需要较大的照明亮度， 或者靠近窗 户边的灯体在白天有光线透射进来时， 应该采取较为省电的降低亮度状态， 又 或者是当部分灯体损坏、 不慎被调控在低照明亮度状态时， 也应该要有其它灯 体为照明亮度的补强， 但该光敏电阻显然不能为机动性的判断， 而无法因应较 亮处、 较暗处或者是两灯体照明交会处， 于照明亮度随时变化时， 作有效照明 亮度补强、 降低， 致使容易发生下列状况：
1、 不能感应既定范围内的光照程度， 来调整灯体自身应该补强、 降低的光 照量， 使得室内呈现过于显著明暗不一的状况。
2、 灯体间不能相互感应光照量而据以补强、 降低光量， 造成过度光照时的 电源浪费， 或者是光照不足时的过暗状况。
3、 室内各活动区块的光照量并非要一致， 但各活动区块也应有维持照明需 求的某光照定值， 因此若不能因应区块间的灯体为相互感应、 改变光量的设置， 显然不能为各区块亮度值的对应调整。 另外， 现有灯体多有采用太阳能板供电， 而太阳能板吸收阳光能量蓄积转 换为电能， 因此其能量储蓄程度受到气候的影响， 阴天时蓄积的能量有限， 而 夜间时则无阳光不能蓄积能量， 若灯体在阴天或夜间发光时无所节制， 则容易 使得太阳能板的蓄积电量快速耗尽， 使灯体发光微弱或者不发亮， 特别是太阳 能板使用在路灯时， 路灯于电力的缺乏势必需配以额外的电厂供电来发光， 如 此即有违以自然供能、 环保的本意， 足见若太阳能板灯体不能依环境亮度变化 而自我调控发亮度时， 则容易浪费不必要的蓄积电能， 也难以达到确实节能省 碳的效用。
由于上述现有灯体不能因应既定范围内的环境亮度而补强、 降低照明亮度， 以及不能节省电力， 或容易造成过暗等缺点， 以及太阳能板灯体蓄积的电力有 限， 若灯体不能自我调控发亮度时， 则容易快速耗尽蓄积电能， 因此本发明人 认有必要加以改良， 应设计一种能因应既定范围内的环境亮度而调整照明强度， 并兼具节省电力功能， 及使环境亮度有一致或有差别性的灯体结构。 发明内容
本发明主要目的是提供一种智能灯光装置， 其可改善现有技术灯体不能因 应既定范围内的环境亮度而补强、 降低照明亮度， 以及不能节省电力， 或容易 造成过暗等缺失。
为了达成上述的目的与功能， 本发明智能灯光装置包括至少一可安装于对 象物的灯壳， 该灯壳内设有至少一发光单元及至少一集光单元， 其中该发光单 元设于灯壳处， 并可受电后往灯壳外界方向发光， 而该集光单元同设于灯壳处， 且该集光单元朝向灯壳外的一待探测区域。
该集光单元设有一微控制单元及一脉宽调制单元， 其中该集光单元可感应 待探测区域的环境光线亮度， 并把感应信息传输给微控制单元运算， 而微控制 单元具有预设的环境亮度值， 待微控制单元经由所接收的感应信息及预设的环 境亮度值相比较后， 计算得出环境亮度的差值， 并将该差值以命令信息传输给 脉宽调制单元， 由脉宽调制单元调控发光单元发出对应该差值的亮度， 以对应 待探测区域的环境亮度增加或降低发光亮度。
本发明中该集光单元进一步包括一差分放大单元及一模数转换单元， 其中 该差分放大单元可感应待探测区域的环境光线亮度， 并把感应信息以讯号放大 后传输给模数转换单元， 模数转换单元则将该感应信息由模拟信息转换为数字 信息并传输给微控制单元运算， 供微控制单元经由所接收的数字信息及预设的 环境亮度值相比较后， 计算得出环境亮度的差值， 提供更为精确的感应、 运算 效果。
本发明中当多个灯壳间产生照明区域相互涵盖状况时， 可将各灯壳的集光 单元朝向适当的相交照明区域为待探测区域， 而微控制单元除具有预设或受调 整命发光单元发出预定亮度的光线外， 集光单元会感受环境亮度给予待探测区 域的照明量， 并与发光单元本欲发出的预定亮度值、 其它灯壳投射过来的亮度 值为复合的差值计算， 使发光单元对应该差值补充或降低照明度， 因此各灯壳 间可以集光单元为交叉辅助感应， 据以对环境亮度、 相交照明区域的灯壳投射 光线亮度为计算， 而决定投射出对应差值的适当光量。 本发明中该集光单元进一步包括一缓冲单元， 该缓冲单元具有预设的缓冲 数值， 当集光单元感测待探测区域方向的亮度改变时间在缓冲数值之下时， 其 会经微控制单元、 脉宽调制单元命令发光单元不需要调整发光亮度， 让本发明 遇待探测区域为环境亮度短时间闪灭时， 集光单元命令发光单元不需调整发光 亮度而避免造成本发明动辄闪烁的状态； 而感测待探测区域方向的亮度改变时 间在缓冲数值之上时， 缓冲单元判断待探测区域处有显著、 非短暂性的亮度改 变， 使缓冲单元配合微控制单元会将亮度改变时间与亮度的数值为整合计算， 经微控制单元、 脉宽调制单元命令发光单元增加或降低发光亮度。 本发明中该集光单元设有感光半导体组件， 该感光半导体组件包含差分放 大单元及发光单元， 成为具有光的发射、 光的接收及光的信号放大的整合组件。
本发明中该集光单元可受控制而改变方向， 借此调整待探测区域的位置， 例如该集光单元可为机械自动或人为调控， 借以受使用者设定该集光单元朝向 适当的待探测区域。
本发明中该灯壳内设有一集光曲面， 而发光单元设于集光曲面处， 借该集 光曲面以反射发光单元发出的光线往灯壳外界方向， 并配合集光曲面的曲率值， 使光线往既定方向照射。
本发明中该灯壳进一步设有一与微控制单元连接的调整单元， 该调整单元 可供手动调整发光单元的发光效果， 因而使用者可依其喜好而手动调整发光单 元的发光亮度等， 提供更为舒适的照明效果。 附图说明

具体实施方式
本发明有关于一种智能灯光装置， 请如图 1和图 2所示， 其为本发明的主 实施例， 包括至少一可安装于对象物 （室内壁面） 的灯壳 1(可为台灯、 日光灯 或者路灯等)， 该灯壳 1内设有至少一发光单元 2及至少一集光单元 3， 其中： 该发光单元 2设于灯壳 1处， 并可受电后往灯壳 1外界方向发光， 而该集 光单元 3同设于灯壳 1处， 且该集光单元 3朝向灯壳 1外的一待探测区域 4， 如 图 1所示， 该灯壳 1实施为安装在室内天花板处， 该灯壳 1 内设有一集光曲面 11， 而发光单元 2、 集光单元 3设于集光曲面 11处， 借该集光曲面 11以反射发 光单元 2发出的光线往灯壳 1外界方向， 并配合集光曲面 3的曲率值， 使光线 往既定方向照射， 即如本实施例所示， 两灯壳 1受各集光曲面 11的影响， 该待 探测区域 4为至少两灯壳 1的发光单元 2的相交照明区域， 而集光单元 3朝向 该待探测区域 4， 另外该集光单元 3可受控制而改变方向 (例如可为机械自动或 人为调控)， 借此调整待探测区域 4的位置， 例如朝向本实施例灯壳 1的相交照 明区域， 或者是非相交照明区域， 而且各灯壳 1可设置多个集光单元 3， 灯壳 1 间的集光单元 3可以单一、 组合式的对应既定待探测区域 4;
该集光单元 3设有一微控制单元 33及一脉宽调制单元 34(进一步包括一差 分放大单元 31及一模数转换单元 32)， 如图 2所示， 其中该差分放大单元 31可 感应待探测区域 4 的环境光线亮度， 并把感应信息以讯号放大后传输给模数转 换单元 32(差分放大单元 31属现有构造，主要可以将感应信息有效的放大输出)。
模数转换单元 32(指 Analog-to-digital converter, 通称为 A/D, 是用于将模拟 形式的连续讯号转换为数字形式的离散讯号的设备)则将该感应信息由模拟信息 转换为数字信息并传输给微控制单元 33运算， 而微控制单元 33(属微型处理器 的一种， Micro Control unit, 通称为 MCU)具有预设的环境亮度值， 待微控制单 元 33经由所接收的数字信息及预设的环境亮度值相比较后， 计算得出环境亮度 的差值，并将该差值以命令信息传输给脉宽调制单元 34(Pulse Width Modulation, 缩写为 PWM， 是将模拟信号转换为脉波的一种技术， 一般转换后脉波的周期固 定， 但脉波的占空比会依模拟信号的大小而改变)， 该增设的差分放大单元 31 及模数转换单元 32提供更精准的感测效果， 让微控制单元 33读取更为精确的 数值。
值得一提的是， 该集光单元 3 设有感光半导体组件， 该感光半导体组件包 含差分放大单元 31及发光单元 2， 成为具有光的发射、 光的接收及光的信号放 大的整合组件； 该灯壳 1进一步设有一与微控制单元 33连接的调整单元 36， 该 调整单元 36可供手动调整发光单元 2的发光效果， 因而使用者可依其喜好而手 动调整发光单元 2的发光亮度等， 提供更为舒适的照明效果。 其后由脉宽调制单元 34调控发光单元 2发出对应该差值的亮度， 据以对应 待探测区域 4处的环境亮度增加或降低发光亮度， 因此该上述集光单元 3的组 成及作用以差分放大单元 31感应并放大对待探测区域 4探得的光线强度， 而模 数转换单元 32、微控制单元 33传输并运算内建环境亮度与待探测区域 4的环境 亮度差值， 经由脉宽调制单元 34命令发光单元 2对待探测区域 4照射对应差值 的补强或降低环境亮度， 因此本发明有下列特点：
1、 当对应为本实施例的相交照明区域为待探测区域 4时， 其可让其中一灯 壳 1的集光单元 3探测另一灯壳 1发光单元 2照射至待探测区域 4的亮度值， 据以自我感应并调整发光亮度， 例如单一活动区块需求某亮度值， 相邻多个灯 壳 1间的集光单元 3可为单一或交叉对应待探测区域 4，当某些灯壳 1发亮度不 足时， 其它灯壳 1 可为均等或不同程度的补足亮度至该活动区块需求亮度值， 让该活动区块保持适当、 恒定的照明亮度。
2、 当非对应本实施例的状态时， 例如窗户边某透光区域可为待探测区域 4， 而靠进窗户灯壳 1的集光单元 3可单一或组合式的朝向该待探测区域 4，让靠近 窗户灯壳 1 的发光单元 2降低光量， 或者透光不足时补强光量， 具有因应外界 透光强度而节省光照电力， 或防止过暗的优点。
3、 室内的活动区块可分为主要活动区、 次要活动区及鲜少活动区， 三活动 区的需求照明度虽不相同， 但是在活动区的过度地带也不能在亮度上未予衔接， 否则容易造成照明亮度明显落差的异样感， 因此活动区相靠进的灯壳 1 应该要 使集光单元 3互相朝往恰当的待探测区域 4，让过度地带的光照量差异较为缓和， 并由各区的其它灯壳 1替过度地带为光照度与各区所需值的差值补强、 降低等， 使得各区域可满足所需的光照量， 让鲜少活动区以省电为主， 主要活动区以明 亮为主， 次要活动区与主要、 鲜少活动区为光照度的柔和衔接， 这都是现有室 内灯体采用光敏电阻不能达到的优点， 本发明实可以集光单元 3 达到机动性感 应既定区域的环境亮度而调整照明量的效果。 并且， 当多个灯壳 1 间产生照明区域相互涵盖状况时， 可将各灯壳 1的集 光单元 3朝向适当的相交照明区域为待探测区域 4， 而微控制单元 33除具有预 设或受调整命发光单元 2发出预定亮度的光线外， 集光单元 3会感受环境亮度 给予待探测区域 4的照明量， 并与发光单元 2本欲发出的预定亮度值、 其它灯 壳 1投射过来的亮度值为复合的差值计算， 令发光单元 2对应该差值补充或降 低照明度， 因此各灯壳 1间可以集光单元 3为交叉辅助感应， 据以对环境亮度、 相交照明区域的灯壳 1 投射光线亮度为计算， 而决定投射出对应差值的适当光
请如图 3所示， 其显示一排多个灯壳 1设置的状态图， 而灯壳 1间有相互 交集的照明区域， 其中多个灯壳 1 的集光单元可朝向交集的照明区域为待探测 区域 4， 设待探测区域 4的需求亮度为 A数值， 外界环境给予的亮度为 B数值， 因此第一个灯壳 1(左边数起)的集光单元 3感测 B数值后， 命令发光单元 2给予 A扣减 B的数值 (假定 A数值大于 B数值)等于 C发光数值， 而 C发光数值让第 二个灯壳 1集光单元 2感测到的亮度为 D数值， 因此第二个灯壳 1命发光单元 2应给予的亮度为 A扣减 B、 D数值等于 E发光数值，而 E数值让第三个灯壳 1 集光单元 2感测到的亮度为 F数值， 因此第三个灯壳 1命发光单元 2应给予的 亮度为 A扣减 B、 F数值等于 G发光数值， 如此可了解灯壳 1间可由待探测区 域 4、 集光单元 3的相互配合， 而获得计算差值予以配出适当发光量的功用， 如 佐以太阳能板的结构使用， 可有效地节省太阳能板灯体的储蓄能量， 而该图 3 是采用并排式为示意说明， 当然多个灯壳 1为多个排、 列或不规则样相搭配时， 计算差值应配予的光量亦随着改变。
再请如图 4所示， 其显示当汽车行经多个排列的灯壳 1时， 左边数起的第 一个灯壳 1会感应汽车车灯的亮度， 而命发光单元 2补强或降低发光亮度， 而 第一、 二、 三个灯壳 1因有待探测区域 4的交集涵盖 (例如第一、 二个灯壳 1相 涵盖， 第二、 三个灯壳 1相涵盖)， 因此第一个灯壳 1改变亮度时， 第二、 三个 灯壳 1也会逐渐感应前一个灯壳 1 的发出亮度而配给汽车适当的照明亮度， 因 此驾驶者可以观看到汽车前方在理想的可视距离处有亮度改变的状况， 供驾驶 者看清路况避免危险， 而汽车通过后， 灯壳 1 可随之发出较低的亮度以节省能 源。
以及， 该集光单元 3进一步包括一缓冲单元 35， 该缓冲单元 35具有预设的 缓冲数值， 当集光单元 3感测待探测区域 4的亮度改变时间在缓冲数值之下时， 其会经微控制单元 33、 脉宽调制单元 34命令发光单元 2不需要调整发光亮度， 让本发明遇待探测区域 4为环境亮度短时间闪灭时，集光单元 3命令发光单元 2 不需调整发光亮度而避免造成本发明动辄闪烁的状态。
而感测待探测区域 4的亮度改变时间在缓冲数值之上时， 缓冲单元 35判断 待探测区域 4处有显著、 非短暂性的亮度改变， 使缓冲单元 35配合微控制单元 33会将亮度改变时间与亮度的数值为整合计算， 经微控制单元 33、 脉宽调制单 元 34命令发光单元 2增加或降低发光亮度。 图 5为本发明投射区环境亮度等级-时间、 驱动电流值等级-时间、灯光投射 区亮度等级-时间的曲线图， 该所述的投射区环境亮度等级是指环境给予投射区 的亮度值， 而驱动电流值等级指当本发明实施于电子机械上时， 电子机械对应 发光亮度的驱动电流值， 而灯光投射区亮度等级则指投射区受到光线投射与环 境亮度的总和值， 因此在该图 5中可见到， 投射区 (可对应本发明的待探测区域 4)环境亮度等级较低时， 发光单元 2应补上较高的投射亮度， 当然驱动电流值也 会提高， 但发光单元 2补上投射亮度配上投射区环境亮度的结果， 仍是让灯光 投射区的亮度总值保持在预设的恒定值处。
