以下, 一边参照附图一边大致说明本发明的优选实施方式。 另外, 本发明的实施方式并不限定于下述实施方式, 能够采用在本发明的技术 构思范围内的各种各样的实施方式。
本实施方式首先提供了一种照明系统, 以下参考图 1从各个方面对 本实施方式提供的照明系统进行介绍。
网络
本实施方式中, 多个光单元 10之间以及多个光单元 10与遥控器 20 之间, 均采用蓝牙网状网络 (Bluetooth Mesh)连接, 进一步地, 本实施 方式中的蓝牙网状网络为基于蓝牙标准协议 4.0 以上的低功耗版本构建 的网络拓扑, 即蓝牙低功耗网状网络 ( BLE Mesh , Bluetooth Low Energy Mesh)
每个光单元 10 以及遥控器 20所具有的蓝牙通信模块 ( 10BLE和 20BLE ) 均为该蓝牙低功耗网状网络中的一个节点, 蓝牙低功耗网状网 络中的节点之间可以双向互传, 光单元 10的蓝牙通信模块 10BLE能够 作为遥控器 20的蓝牙通信模块 20BLE的信号中继, 进而使得遥控器 20 可以借由光单元 10之间的网络连接广播数据,将控制信号发送至遥控器 20信号发送工作距离以外的光单元 10处实施控制。 在传统的灯具控制方式中, 夜晚休息之前, 需要关闭当前房间内的 灯具并离开, 若屋内无其他光源辐照, 就需要用户从关闭当前房间内的 灯具到打开另一房间灯具的这段时间内在黑暗环境中行动, 用户体验较 差。 而通过以上网状网络连接的方式, 用户可以选择暂不关闭当前房间 的灯具, 而在移动至另一房间之后, 利用携带的遥控器 20将原先房间的 灯关闭, 而无需在黑暗环境中行动, 也降低了灯具在初期设计布局过程 中所要考虑的使用要求。
光单元
在一些实施方式中, 光单元 10可以是选自白炽灯、 装饰用白炽灯、 封闭式灯泡、 红外灯、 素灯、 LED灯、 焚光灯、 日光灯、 钠灯、 氣气 灯、 天棚灯、 枝形吊灯、 天棚吊灯、 吸顶灯、 嵌入式天棚灯、 壁灯、 壁 挂灯、 壁直挂灯、 台灯、 落地灯、 路灯、 庭院灯、 门灯、 手电筒、 袖珍 灯、 手提灯、 探照灯、 聚光灯或者其他任何合适的可控光源的一种或几 种的组合, 也可以是上述任何合适的可控光源以及自然光光源、 蜡烛、 油灯等任何合适的不可控光源与能够改变光源照明状态的配件, 如可控 的百叶窗帘、 灯罩、 挡板等之间的组合, 还可以是上述任意一种或多种 光源或配件中的可控的模块或组件。
参考图 2 , 本实施方式中, 光单元 10为 LED灯, LED灯利用 PWM 调光电路 102经由驱动电源 104 , 对 LED灯的发光组件 106进行调光控 制。 本实施方式中, 场景一和场景二以 50%亮度和 100%亮度分别构建 完成, 以之为例, 对本实施方式的系统和方法进行说明, 在本发明的其 他实施方式中, 场景的构建也可以采用其他更为复杂的方式实现, 由于 本实施方式主要涉及光单元 10的分组控制部分,对于场景的构建和切换 仅作简单说明。
本实施方式中, LED灯 (光单元 10) 还具有低功耗的蓝牙通信模块
10BLE , 该蓝牙通信模块 10BLE与光单元 10的 PWM调光电路 102电 性连接, 或者, 与 PWM调光电路 102集成在同一主控芯片 10C中, 能 够基于蓝牙通信模块 10BLE获得的控制指令, 对光单元 10的开关以及 调光参数进行调节。将 PWM调光电路 102与蓝牙通信模块 10BLE集成, 可以有效降低成本。 此外, 为了使集成的蓝牙通信模块 10BLE和 PWM 调光电路 102可以适配于不同种类的光单元 10 , 可以采用多种类型的芯 片分别适配, 也可以采用通用蓝牙模块配合不同外围电路的形式适配, 以降低适配不同类型光单元的成本。
在一些实施方式中, 对于一些至少部分利用配件对其光性能进行控 制的光单元 10, 蓝牙通信模块 10BLE还可以与其配件的控制部分通信 连接,以对配件的工作状态进行控制,例如与灯罩的驱动部件通信连接, 以对灯罩的开闭程度进行调节。
本实施方式中, 光单元 10还具有机械开关 108(例如可以是墙面开 关) , 机械开关 108与光单元 10电性连接, 能够对光单元 10实施开关 控制。
此外, 本实施方式中的光单元 10的主控芯片 10C集成有或者连接 有存储器 10MEMO, 主控芯片 10C能够获取光单元 10的开关状态以及 调光参数, 并将采集的关于开关状态以及调光参数的运行数据保存在存 储器 10MEMO中。 在一些实施方式中, 也可以在照明系统中仅部分光 单元 10的主控芯片 10C中设置存储器 10MEMO, 该一个或者多个设置 有存储器 1 OMEMO的主控芯片 10C能够经由蓝牙通信模块 10BLE建立 的网状网络,获取其他光单元 10的运行数据, 并将运行数据保存在存储 器 10MEMO 中。 仅在部分光单元 10 的主控芯片 10C 中设置存储器 10MEMO, 可以有效降低系统的硬件成本。
在一些实施方式中, 存储器 10MEMO可包含非易失性存储器, 例 如只读存储器 (ROM) 、 可编程只读存储器 (PROM) 、 可擦除可编程 只读存储器 (EPROM) 、 快闪存储器 (FLASH) 或能够在有或者没有 应用电力的情况下存储程序指令或数据的任何其他装置。 存储器还可包 括易失性存储器, 例如随机存取存储器 (RAM) 、 静态随机存取存储器 (SRAM) 、 动态随机存取存储器 (DRAM) 和同步动态随机存取存储 器(SDRAM),还可使用其他类型的 RAM来实现存储。存储器 10MEMO 可使用单个存储器模块或多个存储器模块来实现, 也可以被配置为与光 单元 10或者遥控器 20分离的云端存储器。
分组
本实施方式以家居照明为例进行说明, 其中, 同一照明系统中的多 个光单元 10根据其所处的空间位置(本实施方式中以所在房间为分组条 件) 而被分为两个控制组, 其中, 位于客厅的五个光单元 10被分在第一 控制组 la中, 位于卧室的三个光单元被分在第二控制组 lb中, 同一控 制组中的各个光单元 10之间均具有互联的蓝牙通信信道,不同控制组的 至少部分光单元 10之间也具有蓝牙通信信道。
在本发明的其他实施方式中,该照明系统也可以被使用在商业照明、 户外照明等其他照明形式中, 为不同空间或者区域的场景提供照明。 此 外, 分组条件也不限于基于光单元 10的空间位置, 也可以基于实际使用 逻辑 (例如将相互远离但向同一区域打光的射灯设为一组) 或者其自身 特性 (例如根据灯光颜色、 光强) 等进行分组。 此外, 虽然本实施方式 中, 同一光单元 10在照明系统中可被分在单一控制组中, 但是在本发明 的一些实施方式中, 同一光单元也可以被不同控制组所兼用; 而控制组 的数量也不限于本实施方式中所采用的两个, 可以根据实际需要设置三 个或者四个以上。
蓝牙信号容易受到墙壁、 金属等物体的阻挡, 因此, 不同房间或者 区域内的蓝牙信号强度往往差别较大。 本实施方式中的控制系统可以利 用以上信号强度的差别, 将蓝牙通信方式原先在信号传输方面的缺点转 化为优势, 高效地识别出同一房间或者区域内的所有光单元, 具体的识 别和分组流程将在方法流程部分予以详述。
遥控器
参考图 3 , 本实施方式中照明系统所使用的遥控器 20包括分组控件 200、 场景控件 202以及蓝牙通信模块 20BLE。
其中, 分组控件 200为拨动开关, 系统内的多个光单元 10可以被分 为两个控制组分别控制, 相应地, 采用双位拨动开关在两个控制组之间 进行切换。 在本发明的其他实施方式中, 也可以采用多位拨动开关, 例 如采用四位拨动开关实施四个控制组之间的切换, 还可以增加不与控制 组对应的其他档位来丰富控制功能。
分组控件 200能够在用户交互过程中作为供用户选择分组的机构。 例如, 将分组控件 200拨到对应第一控制组 la的位置: 在分组过程中, 指示本次分组动作将把待分组光单元 10分配到第一控制组 la中; 在控 制过程中,指示本次控制动作将针对第一控制组 la中的光单元 10实施; 在解除或初始化分组过程中, 指示将解除第一控制组 la中光单元 10的 分组或者初始化设置第一控制组 la中的光单元 10。
本实施方式中,遥控器 20的场景控件 202包括消灯按键和两个预设 场景按键, 可以供用户按压, 以将对应的控制组中的所有光单元熄灭(消 灯) 、 设定为 50%光强 (场景一) 或者 100%光强 (场景二) 。 在本发 明的其他实施方式中, 场景控件 202中的按键数量也可以根据控制功能 的需要进行增加或删减。 本实施方式中, 场景设定出厂时即被保存在光 单元 10的存储器 10MEMO中。在本发明的其他实施方式中, 用户也可 以采用单灯调节的方式,在将控制组内光单元 10的调光参数调至满意状 态之后,将光单元 10的调光参数保存在遥控器 20或者光单元 10的存储 器 10MEMO或者 20MEMO中。
本实施方式中, 遥控器 20所携带的蓝牙通信模块 20BLE能够进行 信号强度检测, 且根据信号强度检测结果实施对信号强度高于规定阈值 的单个或者多个光单元的选取、 分组和控制。
遥控器 20 检测到的各蓝牙通信连接的信号强度以 Qualcomm
Atheros®提供的 RSSI(Received Signal Strength Indicator) 值为单位 进行计量, RSSI值为根据 dbm为单位的信号强度计算得出的参考数值, 其数值范围在 0-127之间变化,其中, RSSI=127表示信号无衰减, RSSI=0 表示无信号接收, RSSI的数值越大表示信号强度越高。在本发明的其他 实施方式中, 该信号强度还可以采用 Rx值或者任何合适的计量方式和 计量单位进行计量。
在本发明的一些实施方式中, 遥控器 20 还可以具有多个且均作为 BLE Mesh网络中的节点使用, 不同遥控器 20之间的设定并保存的信息 可以保持同步, 用户可以利用每个房间对应的遥控器 20实施控制。
此外, 本实施方式中的遥控器 20和光单元 10上均设置有指示灯, 包括遥控器 20的指示灯 210和光单元 10的指示灯 110, 指示灯 110与 光单元 10的主控芯片 10C通信连接, 指示灯 210与遥控器 20的主控芯 片 20C通信连接, 以利用指示灯 110、 210的闪烁等状态变化指示遥控 器 20和光单元 10的工作状态, 例如单灯选择状态、 配对状态等。 在一 些实施方式中, 光单元 10也可以利用其自身的状态变化(例如闪烁、 熄 灭和点亮的状态变化或者调光参数的调整, 例如冷暖色调的改变) 实现 指示功能。 在另一些实施方式中, 也可以采用蜂鸣器 (未示出) 的发声 来向用户提示。蜂鸣器或者指示灯可以单独设置在光单元 10上, 也可以 单独设置在遥控器 20上,还可以在光单元 10或者遥控器 20上相互配对 地设置, 或者设置在其他任何合适的位置。
本实施方式中, 遥控器 20上设置有单独控制激活键 204, 长按单独 控制模式激活键 204能够激活遥控器 20和光单元 10的单独控制功能。 被激活单独控制功能的遥控器 20将首先进入信号强度检测模式,检测遥 控器 20与各个光单元 10的蓝牙通信模块之间的蓝牙通信连接的信号强 度, 后续的操作流程将在方法流程部分予以详述, 此处不再赘述。
此外, 遥控器的单独控制激活键 204还集成有单选键的功能, 若在 信号强度检测模式下,检测到信号强度达到规定阈值的光单元 10的数量 超过 1个, 通过单次按压单独控制激活键 204, 还可以在被选中为单独 控制光单元 10TBC的多个光单元 10中依次逐一跳转并进行连接。 跳转 所依照的顺序可以基于信号强度的排序,也可以基于 MAC地址的排序, 还可以是可以任何其他合适的排序方式。
遥控器上的反馈键 206用于收集用户对分组、 单独控制光单元、 参 数的保存、 场景的生成等状态的确认或者取消信息。 此外, 遥控器 20 还具有调光键 208, 能够针对光单元 10的亮度进行调节。 在本发明的其 他实施方式中, 遥控器 20还可以具有其他的调光功能, 例如可以调节单 独控制单元 10TBC色温、 延时消灯功能、 蜂鸣器控制功能中的一项或多 项。
方法流 ^程 (初期设定方法)
本实施方式还提供了可应用于上述照明系统的初期设定方法。
参考图 4, 本实施方式提供的初期设定方法具体包括以下步骤:
501.上电。
用户购买、 安装后, 接通各光单元 10以及遥控器 20的电源。
502.初始化
各光单元 10以及遥控器 20读取固件中的初始数据, 初始化光单元 设置。
503.建网
各光单元 10以及遥控器 20进入配对等待模式, 配对等待模式下, 光单元 10的蓝牙通信模块 10BLE利用短距离广播模式相互通信, 在短 距离广播模式下, 通过设定信号强度阈值, 小于信号强度阈值的信号将 被忽略, 以减少待配对的光单元 10被其他照明系统的网络误绑的可能。
本实施方式中, 光单元 10能够检测其机械开关 108的动作(或者开 关状态) , 响应于上述动作或者状态满足预设条件, 强制初始化光单元 10。 通过以上方式, 即使部分光单元 10被其他网络误绑, 也可以利用其 机械开关 108触发光单元 10的初始化, 将已被误绑的光单元 10强制从 其他网络中解绑。
例如, 可以将一定时间内反复开闭机械开关 108的动作 (抑或检测 到开关状态的反复切换)作为光单元 10初始化的触发动作, 响应于检测 到该触发动作,光单元 10将被强制性地初始化为出厂状态而从已经配对 完成的 BLE Mesh网络中移除。 在一些实施方式中, 响应于来自不同房 间或区域的分别确认,将这些不同房间或区域内的光单元 10加入同一个 网络中。
S04确认建网结果。
用户可以通过光单元 10以及遥控器 20上的指示灯 110, 210的指示 获知建网结果。若光单元 10与遥控器 20配对完成, 光单元 10与遥控器 20上的指示灯 110、 210将借助闪烁行为、 点亮熄灭、 闪烁频率、 呼吸 灯变化等方式通知用户建网结果。
若用户利用反馈键 206确认建网成功, 则转向 S05分组步骤。 本实 施方式中, 建网成功后, 指示灯 110将闪烁一次后点亮, 作为预定的提 示方式。
若用户利用反馈键 206取消建网结果, 则返回至 S01上电步骤。
S05分组。
光单元 10 自动或者响应于遥控器 20的指令, 进入分组设定模式。 在分组设定模式下, 可以利用任何合适的方式, 实现对于光单元 10 的分组, 将照明系统中的多个光单元 10编制为若干控制组。
S06确认分组结果。
若用户利用反馈键 206确认分组结果, 则初期设定完成。
若用利用反馈键 206取消分组结果, 则转向 S05分组步骤。
方法流程 (分组控制方法)
在初期设定完成之后,当遥控器 20上的拨动开关 200被拨动至第一 档位 (组一) 时, 可以对该档位对应的第一控制组 la 中的若干光单元 10作为一个整体进行分组控制。 例如, 可以通过操作场景控件 202, 调 取预先设定的场景下每个光单元 10的调光参数信息,并相应地载入到第 一控制组 la的各个光单元 10中, 实施分组控制。
此外, 在一些实施方式中, 还可以配合遥控器 20的其他控件实现组 内光单元 10的分组解除 (仍在网络中) 和网络解绑的操作。 例如, 当将 拨动开关 200拨动至第一档位 (组一) 时, 若检测到用户对遥控器的预 定动作, 可以将第一控制组 la解除。 网络解绑的操作可以在光单元 10 处利用光单元 10上安装的机械构件激活并实施,将单个光单元初始化而 从网络中解绑;也可以从遥控器 20处分组地进行,例如可以将拨动开关 200拨动至第一档位 (组一) , 并通过预定动作, 将第一控制组 la内的 所有光单元 10全部初始化, 从网络中解绑。
方法流程 (单独控制方法)
对于已经由以上初期设定方法完成分组的系统, 本实施方式还提供 了一种利用能够实施分组控制的遥控器 20来实施单独控制的控制方法。
以用户需要选择特定的一个光单元 10作为单独控制光单元 10TBC 为例, 以下给出了本实施方式提供的单独控制方法至少能够使用的几种 策略:
策略一: 在一些实施方式中, 可以将 RSSI值的规定阈值设置得较 高, 例如可以为 110~125 , 只有高于这一规定阈值的光单元 10方可被选 中。 该较高的规定阈值能够使得遥控器 20仅可在贴近该光单元 10时方 可将该光单元 10选中为单独控制光单元 10TBC。
通过以上方式,用户可以将遥控器 20贴近需要执行单独控制的光单 元 10 ,将该光单元 10选中为单独控制光单元 10TBC,并实施单独控制。 响应于被选中为单独控制光单元 10TBC, 光单元 10的指示灯 110发出 提示信息, 通知用户该选中动作已经完成。
具体地, 参考图 5和图 6, 以选中某射灯作为单独控制光单元 10为 例, 该单独控制方法包括以下步骤:
首先,长按单独控制激活键可以激活遥控器 20的信号强度检测模式, 进入信号强度检测模式的遥控器能够执行:
S07检测步骤, 检测各个光单元 10与遥控器 20之间的无线连接的 信号强度。
当用户手持遥控器 20时,遥控器 20与各个光单元 10的距离均较远, 客厅内隶属第一控制组 la的每个光单元 10的信号强度均无法达到规定 阈值, 遥控器 20保持该信号强度检测模式, 持续地检测各个光单元 10 与遥控器 20之间的蓝牙连接的信号强度。 为了将目标光单元 10选中, 用户可以移动至目标光单元 10附近, 并托举遥控器 20与目标光单元 10 进一步接近, 当遥控器 20与目标光单元 10的接近程度达到阈值 (在一 些实施方式中, 该阈值可以与信号强度的规定阈值相互转换) 时, 遥控 器 20与目标光单元 10之间的蓝牙连接的信号强度也将达到规定阈值。 该时刻的检测结果如图 5所示。
在一些实施方式中, 当遥控器 20的分组控件 200位于第一控制组 la相对应的档位时, 也可以仅检测第一控制组 la内各个光单元 10的信 号强度。
在 S07检测步骤之后, 执行:
S08对象选择步骤, 选中当前光单元 10与遥控器 20之间的无线连 接信号强度达到规定阈值的光单元 10 ,作为单独控制光单元 10TBC。 由 于当前时刻, 目标光单元 10与遥控器 20之间的无线连接信号强度达到 规定阈值, 目标光单元 10将被选中, 作为单独控制光单元 10TBC。
当目标光单元被选中, 作为单独控制光单元 10TBC时, 执行:
S09提示步骤, 当前光单元与遥控器之间的无线连接的信号强度达 到规定阈值, 而被选中为单独控制光单元时, 通过预定方式, 发出提示 信息。
本实施方式中, 光单元 10的指示灯可以通过闪烁、 点燃、 熄灭或者 任何合适方式发出提示信息。 在其他实施方式中, 也可以利用单独控制 光单元 10TBC本身的规定闪烁或者规定开关来发出提示信息。在另一实 施方式中, 也可以利用蜂鸣器的声音来发出提示信息。
接着, 执行:
S10单独控制步骤, 对 S08对象选择步骤所选中的单独控制光单元 10TBC实施单独控制。
通过以上方式, 用户可以精确地选择特定光单元 10进行单独控制, 有效提高遥控器 20选择光单元 10的精度。
策略二: 在一些实施方式中, 可以将 RSSI值的规定阈值设置在较 低范围内 30~60, 以 60为例。 由于只有高于这一阈值的光单元方可被选 中, 其他房间的灯具 (例如卧室灯一、 卧室灯二等) 由于存在墙壁或者 金属的干扰信号强度较弱, 无法被选中, 而在同一房间的灯具, 由于不 存在墙壁或者金属的干扰, 信号强度很容易达到规定阈值, 用户可以通 过合理设置该规定阈值的大小以及通过在客厅移动遥控器 20 ,在有限的 次数内将所要选取的光单元 10全部选中。
如图 5所示,遥控器 20内预设 RSSI值大于 60的光单元将被选中, 当用户将遥控器 20移动至图示的位置时, 客厅内的各个光单元 10由于 处于同一空间内, 信号传输较少受到墙壁、 金属的干扰, 其蓝牙通信模 块 10BLE的信号强度相较于其他房间的光单元 10更高, 因此, 在图示 位置, 客厅内的其他各个光单元 10的蓝牙信号强度均高于 60, 可以一 次性地将所有客厅内的光单元 10选中,对客厅内的所有灯具统一实施调 光控制。 通过以上方式, 该分组设定方法可以将蓝牙通信原先在信号传 递方面的缺点转化为优势,有效提高遥控器 20在分组的过程中对光单元 10进行选取的效率。
本实施方式中,遥控器 20上的单独控制激活键 204还集成有单选键 的功能, 通过单次按压单独控制激活键 204, 还可以在被选中为单独控 制光单元 10TBC的多个光单元 10中依次逐一跳转并进行连接。 若要进 一步实施对于某个单独光单元的单灯控制, 还可以利用该单选键功能, 逐一跳转并切换至需要实施单灯控制的光单元, 与之建立持续的蓝牙通 信连接, 并对其实施单灯控制。 在本发明的另一实施方式中, 若要实施 对于某个光单元 10的单灯控制, 也可以将遥控器 20配置为仅对达到规 定阈值的多个光单元 10中的信号强度最高者实施单灯控制。
策略三: 在一些实施方式中, 若仅需要对客厅内的部分光单元 10 单独控制, 可以首先将 RSSI的阈值规定为 30~60内的某数值, 以 60为 例, 与策略二类似地, 对应的蓝牙连接的信号强度高于 60的光单元 10 将被选中, 亦即在类似位置可以将客厅内的所有光单元 10全部选中,作 为单独控制光单元 10TBC。
之后, 继续检测遥控器 20接收的信号强度, 响应于检测到当前光单 元 10与遥控器 20之间的蓝牙连接信号强度大于 120, 移除该光单元 10 的选中状态。
类似地,用户还可以在初步选择部分光单元 10作为单独控制光单元 10TBC之后, 建立其他光单元 10的选中状态、 锁定部分光单元 10的选 中状态或者移除部分光单元 10的选中状态。
虽然本实施方式中的策略一到策略三中, 规定阈值均被设置为下限 值, 只有信号强度高于规定阈值的光单元 10才会被选中。但在本发明的 一些实施方式中, 规定阈值也可以作为上限值, 以限定信号强度的具体 范围。 例如, 可以通过调整规定阈值为上限值 =100 , 使信号强度<100的 光单元 10均被选中并实施单独控制, 用户可以使用上述方式, 快速地将 其他房间的全部光单元 10关闭。 在一些实施方式中, 信号强度的范围也可以通过多个阈值的配合使 用而被限制为多段的范围,例如可以设定信号强度达到第一规定阈值(上 限值 60) 或者达到第二规定阈值 (下限值 100) 的光单元 10被选中。
此外, 在一些实施方式中, 检测到的信号强度除了可以使用例如 RSSI值、 Rx值等方式计量, 也可以将其等价转换为距离数值后, 直观 地呈现给用户。例如 RSSI>100对应 lm以内的范围, 则在说明书或者遥 控器的用户界面上以相应方式记载或者显示距离数值。
优选地,光单元 10的蓝牙通信模块 10BLE安装在光单元 10使用时 朝向用户的一侧, 以进一步防止光单元 10被安装完毕后, 蓝牙通信模块 10BLE的信号受到墙壁或者光单元 10本身的干扰, 在 S05分组步骤中 因其信号受阻而难以被选中。
在 S 10单独控制步骤之后,本实施方式的单灯控制方法还可以包括:
S 11设定保存步骤,若接收到用户利用反馈键 206反馈的确认信息, 则更改特定光单元的调光参数并将更改后的调光参数保存在存储器 10MEMO或者存储器 20MEMO中,进而对场景一和场景二等场景控件 202所对应的调光参数的出厂设定进行修改。
S 12场景生成步骤,基于被保存的同一控制组中的各个光单元 10的 调光参数, 为该控制组创建场景并保存在存储器 20MEMO中。
在一些实施方式中, 用户可以利用遥控器 20上的场景设定按键(未 示出) 进入场景设定模式, 在对控制组内所需调整调光参数的光单元均 完成单独控制之后, 将最终的单独控制结果确定、 汇总并生成为场景, 将该场景保存在存储器 20MEMO中,供遥控器 20在后续的控制过程中 利用场景控件 202直接调用, 以重现用户自定义的场景设定。
通过以上方式, 本实施方式提供的控制方法可以利用无图形用户界 面, 或者只具备简单图形用户界面的遥控器 20 , 实现对于复杂照明系统 的分组控制和单独控制。 而且, 系统内各光单元 10、 各控制组的控制可 以利用同一个遥控器 20实施, 极大地提高了控制设备的集成度。 再者, 基于单独控制结果还可以生成由用户自定义的场景, 供分组控制的场景 控件 202直接调取。
至此, 已经结合附图描述了本发明的技术方案, 但是, 本领域技术 人员容易理解的是,本发明的保护范围显然不局限于这些具体实施方式。 在不偏离本发明的原理的前提下, 本领域技术人员可以对相关技术特征 作出等同的更改或替换, 这些更改或替换之后的技术方案都将落入本发 明的保护范围之内。
