(5) Specific implementation methods

Below in conjunction with accompanying drawing and embodiment, the utility model is described further:

As shown in Figure 2, the block diagram of the circuit principle is composed of solar panels, intelligent controllers, batteries, new centralized control circuits, and LED light sources. The solar plate converts the received solar light and heat into electrical energy, and charges the battery through an intelligent controller. The intelligent controller has the functions of automatically detecting the amount of existing electricity and implementing automatic protection for overcharging and overdischarging. The output end of the storage battery is connected to the centralized control circuit to deliver controlled electric energy to the LED light source, thereby emitting constant light. the

Example:

As shown in Figure 3, the new centralized control light source circuit is composed of centralized control circuit 1, light source circuit 2, and LED 3. The centralized control circuit 1 is mainly composed of a control module LM317, and fewer components reduce internal friction accordingly. The control module LM317, also known as an adjustable three-pin integrated voltage regulator and constant current chip, can be purchased from the market. It has various functions required by the voltage stabilized power supply. When assembling, its one-pin ADJ, two-pin UOUT, and three-pin VZV should be connected to both sides of the resistor R of VCC respectively. The "centralized control" means that there is no control setting except for one control circuit in the entire light source circuit. the

In the light source circuit 2, at least 16 LEDs should be selected to form a group of square-shaped LED1, and the two units in the group are respectively connected in series and parallel, and then connected in parallel, wherein the positive pole is connected to VCC, and the negative pole is connected to GND. Multiple sets of LEDn can be connected in parallel in the back to form a higher power LED light source circuit. The LEDs are self-photodiodes of all large and small powers; the light source circuit is composed of "n" square LED1

The square structure and multi-head connection are conducive to maintaining the front and rear balance of "voltage drop" and improving the luminous efficiency. the
