参阅图 7所示,为本发明的电路原理示意图之四,与电路原理示意图之二基本相同, 不同处是交 /直流电源电路 3采用开关电源。
本发明具体使用时, 参阅图 1和图 8所示, 智能灯可通过国际标准的灯头 10直接 连接在普通照明线路的 220V交流输入线路的灯座 16上, 通过原照明开关 17就可以控 制智能灯开关,达到正常照明开启和关闭灯光及无市电自动转应急照明的目的, 无需改 动用户线路, 安装、 使用非常方便。
本发明工作原理: 本发明通过其单片机 5a来控制交、 直流照明转换, 充电控制, 其中分流电阻 Rl、 R2串联后一端与比较器 4a反相输入端连接并与可充电电池 6的正极 相通, 作基准电压, 串联的分流电阻 Rl、 R2中间与比较器 4a的正相输入端连接,并与 同向串接的保护二极管 Dl、 D2的中间相连, 其中保护二极管 Dl、 D2起保护作用, 比较 器 4a的正相输入端接虑波电容 Cl, 其起到抗干扰作用。 工作时(1 )当市电 11正常时, 比较器 4a的正相的电压大于或等于反相的基准电压, 比较器 4a输出高电平输出给单片 机 5a, 故单片机 5a为交流供电, 此时 LED灯组合体 2亮。 (2 ) 当市电 15无时, 由于 线路上有其他电器存在所以内阻较低(小于兆欧), 故比较器 4a的正相的电压低于反相 的基准电压,比较器 4a输出低电平输出给单片机 5a,故单片机 5a为直流供电,此时 LED 灯组合体 2亮。 (3) 当用户通过开关关灯时, 线路为高阻, 此时所述的比较器 4a的结 果与 (1 ) 相同, 此时可充电电池 6不能供电, 所以 LED灯组合体 2也不亮。
本发明的一种两用智能灯还具有 (1 ) 开启灯光时为自动由暗逐渐变亮, 可防止了 开启时电压不稳定对 LED的大电流冲击;关闭时为由亮逐渐变暗,防止 LED温度的突变, 有效地保护了 LED的使用寿命。 (2) 当内部电池使用到某一容量时(%;), 可分级逐渐减 少 LED亮的个数或组数(通过增加单片机的电池供电的控制输出一路以上, 即增加三极 管 Q3), 使用分级或分组亮灯以达到有效地保护电池照明的使用时间达到真正的节能目 的。 (3) 按一定的应急照明时间 (定时)分级逐渐减少 LED亮的个数或组数来达到节能 目的。
总之, 本发明虽然列举了上述优选实施方式, 并且可通过改变 LED的数量和排列结 构安装于其它照明灯具上 (传统灯头上安装的灯具、 吸顶灯、 条型灯、 吊挂灯等), 但 是应该说明, 显然本领域的技术人员可以进行各种变化和改型。 不论是外加还是内置运 算放大器作比较器的,并且使用了所述的 Rl、 R2、 Dl、 D2、 CI连接结构的, 因此, 除非 这样的变化和改型偏离了本发明的范围, 否则都应该包括在本发明的保护范围之内。
