具体实施范例
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方 案进行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本实用新型一部分实 施例， 而不是全部的实施例。基于本实用新型中的实施例， 本领域普通技术人 员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型 保护的范围。
由图 1可见， 一种 LED与荧光灯照明控制装置， 该控制装置包括人体探 测器 1、 控制器 2、 LED驱动电路 4、 荧光灯驱动电路 6和照度传感器 9， 其中 人体探测器 1、 照度传感器 9、 荧光灯驱动电路 6和 LED驱动电路 4分别与控 制器 2相连； 所述人体探测器 1为热释电人体红外探测器或超声波探测器， 用 于检测周边是否有人体进入与活动， 将检测到的数据输入给控制器 2 ; 所述的 照度传感器 9， 用于检测周边环境的亮度， 将检测到的亮度数据输入给控制器 2； 所述的 LED驱动电路 4， 与控制器 2的 K2相连接， 由 K2控制 LED驱动电 路的导通与断开，进而达到控制 LED的开与关； 所述的荧光灯驱动电路 7为电 子镇流器或电感镇流器， 与控制器 2的 K3相连接， 由 K3控制荧光灯驱动电路 的导通与断开， 进而达到控制荧光灯的开与关； 其中， 当照度传感器 9检测到 环境亮度低于设定值 D1时， 同时人体探测器探测到探测范围内有人体进入或 活动时 K3才导通， 当不存在人体时控制 K2导通， K3断开； K2和 K3正常时工 作状态互为相反， 但两个切换的时候， 先让 K3导通， 经延时一段时间后才断 开 K2开关， 在环境亮度低于设定值时， 保证同一时刻不出现同时关断 K2和 K3的情况。
由图 2可见， 当有人体进入由微波的多普勒效应产生、 由热释电红外传感 器产生或由超声波的多普勒效用产生构成的人体探测器 11的探测区域内， 人 体探测器 11 得到一个微弱的电信号， 并加以放大后传送到信号处理判断电路 12， 由信号处理判断电路 12处理并判断信号是否真实有效为人体进入探测区 域； 环境照度传感器 13也将信号传递到信号处理判断电路 12， 由信号处理判 断电路 12处理并判断环境照度是否低于设定值或高于设定值， 输出一路控制 信号到信号处理延时与执行控制电路 14; 输出一路控制信号传递到执行控制 电路 15， 信号处理延时与执行控制电路 14先对输入的控制信号的极性进行取 反操作并延时； 当信号处理判断电路 12判断出环境照度感应器检测到环境的 亮度低于用户实现的设定值时， 则向信号处理延时与执行控制电路 14和执行 控制电路 15输出控制信号， 执行控制电路 15的控制动作为开启,而信号处理 延时与执行控制电路 14由于对信号反相后反而由原来的开启状态经由一段延 时后变为关闭状态。 信号处理延时与执行控制电路 14连接 LED驱动器 16， LED驱动器 16连接 LED灯 17， 信号处理延时与执行控制电路 14通过控制 LED驱动器 16来最终控制 LED灯 17。而另一路执行控制电路 15连接电子镇 流器或电感镇流器 18， 电子镇流器或电感镇流器 18连接荧光灯管 19， 执行控 制电路 15通过控制电子镇流器或电感镇流器 18来最终控制荧光灯管 19。
同样：可以实现为当信号处理判断电路判断出环境照度感应器检测到环境 的亮度高于用户实现的设定值时， 需要同时关断 LED和荧光灯； 可以实现为 当人体探测器检测到人体离开的信号时， 同样需要实现控制先开启 LED, 延 时一段时间后再关闭荧光灯； 进而实现在 LED和荧光灯切换光源时都可以保 证不出现同时关闭的情况发生。
以上所揭露的仅为本实用新型一种实施例而已，当然不能以此来限定本实 用新型之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部 分流程，并依本实用新型权利要求所作的等同变化或满足不同应用所加的部分 附加电路， 仍属于实用新型所涵盖的范围。
