IX. Description of the invention: [Technical field to which the invention pertains] A power control circuit for a solar lighting system, in particular, a circuit for determining the amount of power stored in a solar lighting system to adjust the power of the lighting. [Prior Art] In the era of energy shortage and environmental protection becoming an urgent need, solar panel power generation has become one of the alternative sources for promotion and utilization, and it is too flexible to use solar energy to generate electricity with a high-capacity storage battery; Solar power can be used for public lighting, and some public lighting equipment • 帛 曰 曰 曰 曰 曰 曰 ' ' ' ' ' ' ' 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若The time when the device is scheduled to turn off and the energy is turned off, and the use of power lighting after sunset is used to enable the public lighting device to regularly perform the cycle of energy storage and lighting on day and night, respectively. Public lighting equipment makes good use of environmentally friendly energy. However, the above-mentioned conventional architecture has the inherent obstacles of solar power generation. When the weather is not good, the solar panels absorb the sunlight and effectively generate electricity, which makes the battery charge less than the design time. Value, the battery still needs to be released during the night, if the battery is not good for several consecutive days, the battery is not the same. 』It can't be lit normally or extinguished at night, causing public safety problems; and then, ^Long-term weather is not good, so that the battery is often kept at low power, which will significantly shorten the effective life of the battery, and cost a lot of maintenance and maintenance. Costs; as noted above, solar lighting systems that utilize public lighting in conventional techniques do not have mechanisms to improve such deficiencies, resulting in difficulties in promotion or loss of use. SUMMARY OF THE INVENTION As described in the prior art, the conventional solar lighting system uses only the timing controller to illuminate with a fixed output power during a fixed slump period, thereby causing the weather to affect the lack of the lighting system, and thus the object of the present invention. That is, a control circuit design is provided to enable the lighting system to adjust the output power according to the solar panel's 5 1362159 power during the lighting period, thereby reducing the loss of the solar lighting system due to poor weather. The invention relates to a power control circuit of a solar lighting system, the solar lighting system comprising at least one solar panel connected to a charging controller, thereby charging at least one battery, and controlling a driving unit to obtain a battery by a power control circuit Saving at least one light bulb group, wherein the power control circuit includes a power detection circuit and an output control circuit, the power detection circuit is connected to the solar panel and the battery, and further generates power according to the solar panel and The battery power correspondingly generates a power generation signal and a power storage signal, and the output control circuit is connected to the power detection circuit to obtain the power generation signal and the power storage signal to determine the output power of the light bulb group. The power control circuit further sets a timing mode for controlling the lighting period and a power distribution mode having a different power output ratio during the fixed lighting period, and generates a driving signal in the timing mode or the power distribution mode to activate the Drive unit, converted by the drive unit Saving the electric power and outputting a driving power to illuminate the light bulb group; adjusting the output power by determining the power generation amount and the electric storage amount by the above-mentioned circuit structure, the solar lighting system can have different working modes and adjust the lighting according to the weather change The power used by the system achieves the effect of extending the battery power supply time, thereby slowing the loss of the solar lighting system due to poor weather.
