Background technique

According to the BP Energy Report and EIA related data, the global power consumption in 2004 was as high as 15.4 million gigawatts. It accounts for 1/3 of the global energy consumption, while motors, lighting and power supply rank in the top three, with the combined proportion of the three items reaching 61%. While the quality of life has been generally improved, people have also put forward higher requirements for green, environmental protection, and energy conservation. The advantages of LED lights are energy saving, environmental protection, and long life, and LED lights have the characteristics of ordinary diodes, and can work in high-speed switching states. For example: there are 10 small rooms in a house, and each small room uses a 3W lamp LED lights, 10 rooms are lit at the same time, it will consume 30W of power. If the LED lights of these 10 rooms are lit up sequentially at high speed, only one light is on at the same time point, and because of the high speed, it will be seen that all the LED lights of all 10 rooms are lit up. This will save 50%-80% of electric energy. However, in the prior art, there is no such energy-saving control system designed for LED lighting lamps.

Detailed ways

Preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

Example:

As shown in Figure 1 and Figure 2, an LED lighting energy-saving control system includes a field effect switch circuit, a counter, a light control circuit, an oscillation circuit and a power supply for the field effect switch circuit, the counter, the light control circuit, and the oscillation circuit respectively Module, the output end of the light control circuit and the output end of the oscillation circuit are respectively connected to the first input end and the second input end of the counter, and the output end of the counter is connected to the input end of the field effect switch circuit end connection. The counter is a decimal counter, and its 10 output terminals output high levels in order to control the work of the CMOS power field effect transistor. The oscillating circuit is composed of a first inverter U1A, a second inverter U1B, a first resistor R1 and a first capacitor C1, and the generated waveform is output to the counter after passing through the third inverter U1C.

In this embodiment, the function of the light control circuit is very simple, that is, to prevent the LED lights from being turned on during the daytime. Resistor R01 and third resistor R3 form a voltage divider circuit. During the daytime or when there are lights nearby, the resistance value of resistor R01 will be very small, so that the input terminal of the fourth inverter U1D will be pulled high, and the output terminal will become low potential. The potential of the output terminal directly controls the transistors Q11 and Q12. Since the low-potential transistors Q11 and Q12 are all cut off, the output signal of the oscillation circuit cannot be sent to the input terminal of the counter due to the cut-off of the transistor Q12, and the counter stops working. At night, the resistance value of the resistor R01 will be very large, so that the input terminal of the fourth inverter U1D is pulled down by the third resistor R3, and the output terminal becomes a high potential. The transistors Q11 and Q12 will be turned on at the same time, and the transistor Q11 The conduction is to make the input point of the fourth inverter U1D firmly locked at a low potential (to prevent the change of light from affecting the normal operation of the LED lamp). The conduction of the transistor Q12 sends the signal of the oscillation circuit to the counter, so that the counter starts Counting work, the output pins of the counter will light up the LED lights in turn.

One of the 10 LEDs in the circuit of this embodiment is not controlled by light, and can be used according to the actual situation when wiring.

The counter part is composed of a decimal counter, and its 10 output terminals output high level in order to control the work of the CMOS power FET. The on-resistance of this FET should be very small (its size will affect the efficiency of the entire circuit).

Energy saving is achieved by using the characteristics of light and persistence of vision. In such a period of energy shortage, the inventors found that many places would turn on lights in places that should not be turned on during the day. The utility model can control the LED lamp to be unable to be turned on in a bright place, and can automatically lock the turned-on LED lamp in a dark place so as not to be affected by its own light. Use this function to turn on the switch (the light is off) when you go out during the day, and the light will automatically turn on when you come back at night.

Finally, it should be noted that the above is only a preferred embodiment of the utility model, rather than a limitation to the technical solution of the utility model, and any equivalent replacement or corresponding improvement made to the technical features of the utility model is still within the scope of the utility model. within the scope of protection.
