After receiving the voltage signal from pin 3 of the programmable MCU U2, the switch is turned off, and the value of pin 6 VCC1 of the LED constant voltage driver IC U1 inside the LED light source control circuit 7 rises to the preset value V, and at this time, the LED The constant voltage drives the ICU1 to be in the open state, and output voltage to the LED light source, that is, the LED light source is in the light-on state; since the photoreceptor and the photosensitive signal detection circuit 5 are inside the light-controlled lamp, when the When the phase signal V phase of the power supply circuit 1 is at 0°, 180° and 360°, pin 6 of the programmable MCU U2 will simultaneously receive the self-reflected light and natural light of the LED light source provided by the photosensitive signal detection circuit 5 The V2 value of the mixed signal (in this embodiment, the value is taken three times, of course it can be more, and this process lasts about 30s to ensure that the sampling signal is correct), and the V1 and V2 values fed back by the internal module of the programmable MCU U2 Perform difference processing (i.e. V2-V1) to get the difference (three groups or more), then the module randomly selects two groups from the three groups (or more groups) of difference and then performs difference processing, and finally converts the obtained The result is compared with the second preset value, if it is less than the second preset value (in this embodiment, the set illuminance is 150Lux, the data is obtained from multiple tests with an illuminance meter according to the actual daylight process), it is judged to be still dark Or if the surrounding environment is very dark, you need to turn on the light, so as to distinguish the self-reflected light of the LED light source from the natural light. light, prevent self-excitation, ensure that the LED light source is on (the LED light source is bright), and will not be affected by the self-reflected light of the LED light source; after that, the V2 value remains basically unchanged throughout the night. When the environment becomes bright or the sky is bright, the V2 value Changes will occur. At this time, when the phase signal V phase of the power supply circuit 1 is at 0°, 180° and 360°, the 6 pins of the programmable MCU U2 will receive the natural light provided by the photosensitive signal detection circuit 5 The change signal and the mixed signal V3 value of the self-reflected light of the LED light source (take three values in this embodiment, of course, can also be more, this process lasts about 30s, to ensure that the sampling signal is correct), through the programmable MCU U2 The internal module performs difference processing on V2 and V3 (i.e. V3-V2), if the difference is greater than the second predetermined value, the pin 3 of the programmable MCU U2 will output a high level, and the switch The switch of the control circuit 6 is turned on, and the value of pin 6 VCC1 of the LED constant voltage driver IC U1 inside the LED light source control circuit 7 is pulled down to the preset value V. The output voltage of the LED light source, that is, the LED light source is in the state of turning off the light; in this cycle, automatic judgment and automatic switching control of the light are realized according to the light.
另外，在某些特殊情况下如果光控灯出现误动作，如灯长亮，则通过所述中央控制器2进行如下预置功能：在灯亮起来的时候，计时器开始计时(假设晚上6点)，设定在若干小时后(如13个小时后为早上7点)，灯如果还没灭，系统判断为出现故障，并控制所述开关控制电路6开关开启，所述LED光源控制电路7内部的LED恒压驱动IC U1的6脚VCC1被拉低到预设值V关，此时LED恒压驱动IC U1处于关闭状态，不向所述LED光源输出电压，即所述LED光源处于关闭熄灯状态，以实现强制关闭LED灯；然后重新初始化，重复上述检测光感信号的过程，以决定是否开灯或者关灯；上述预置的时间间隔可根据实际使用环境进行设置调整。In addition, in some special cases, if the light-controlled lamp malfunctions, such as the lamp is always on, the following preset function is performed by the central controller 2: when the lamp is on, the timer starts counting (assuming 6 o'clock in the evening) ), set after several hours (as 7 o'clock in the morning after 13 hours), if the light has not gone out, the system judges that there is a fault, and controls the switch control circuit 6 switch to open, and the LED light source control circuit 7 The 6-pin VCC1 of the internal LED constant voltage driver IC U1 is pulled down to the preset value V off, at this time the LED constant voltage driver IC U1 is in the off state, and no voltage is output to the LED light source, that is, the LED light source is turned off Turn off the light to realize the forced turning off of the LED light; then re-initialize and repeat the above process of detecting the light sensor signal to decide whether to turn on or off the light; the above preset time interval can be set and adjusted according to the actual use environment.
