The first power supply device 21 is completed, li 230 〇^2; t?; a regenerative energy device 212 and a battery 214, & 匕V/B Regenerating the source splicing 212 i or the solar power generation module, and selecting two according to requirements: the γ Γ two electric connection is connected to the regenerative energy device 212 and the switch generates a force, and the 胄 battery 214 is used to store the regenerative energy device 212 4 forces. The second power supply device is fine for the mains 22 AC conversion 1 224 'where DC/AC transfer & 222 and switch element (4), and DC / AC conversion; t = : electrical AC conversion to the required power supply Form re-= 200933328 26518twf.doc/p The luminaire 250 is electrically connected to the switching element 230, wherein the switching element 23 is used to control the supply of lightning energy to the luminaire 250 by the first power supply device 210 or the second power supply device 22 . The control component 240 is electrically connected between the luminaire 25 and the illuminating component 230, and the control component 240 is configured to control the amount of power supplied by the first power supply device 21 or the second power supply device 220 to the luminaire 250 to adjust the brightness of the luminaire 250. . In view of the above, the luminaire 250 of the present embodiment is a street lamp for use in a street, or other luminaires for indoor or outdoor use. Take street lights as an example. The regenerative at* source device 212 in the first power supply device can convert solar or wind power into electrical energy and store the electrical energy in the battery 214, typically in the event of a sun or wind during the day. When the night is turned on, the luminaire 25 is turned on to increase the visibility of the street. At this time, the switching element 230 detects the amount of power in the battery 214, and then determines the result of the detection to be powered by the first power supply device 210 or by the second power supply. The device 22 is powered to the lamp 25 〇. In detail, in order to utilize the regenerative energy efficiently, in the smart power saving system 200 of the present embodiment, the switching element 230 normally controls the power supply of the luminaire 250 by the first power supply device 210. However, sometimes the energy of the regenerative month b source device 212 converted from solar energy or wind power and stored in the battery 214 is not sufficient to provide the electric power of the lamp 250 to be lit overnight, so that when the switching element 230 detects that the battery 214 can be supplied to the lamp 250 When the amount of power is less than a preset value, the preset value is 1 volt in the embodiment, the switching element 230 switches the power supply source, and the second power supply device 220 supplies power to the luminaire 250 ′ so that the luminaire 250 can maintain the whole The night lights up. It is worth noting that since the brightness of the luminaire 250 is proportional to the power consumption of the luminaire 250 for 200933328 26518 twf.doc/p, the brightness of the luminaire 25 可以 can be adjusted by the control element 24 ,, thereby saving the power consumption of the luminaire 250. the amount. In detail, the 'control element 240 can be set to control the brightness of the lamp 25 定时, for example, after five o'clock in the afternoon, after the sky is darkened, the vehicle and pedestrians on the road are more f, and the visibility of the environment is higher. Therefore, the luminaire 25 〇 maintains a high degree of shell, and the corresponding amount of power required for the luminaire 25 较大 is large. For example, after two o'clock in the morning, there are fewer vehicles or pedestrians passing through the road, and the visibility of the environment needs to be lower. Therefore, the brightness of the lamp 250 is reduced to 1% to 30% when the lamp is relatively bright, and the corresponding lamp is 25〇. The amount of power required will be small. In this way, the brightness of the luminaire 250 is adjusted by the demand to save the power consumption of the lamp 25 。. In addition, the smart power saving system 2 can further include a sensor 260 electrically connected to the control element 240. The sensor 260 can be disposed adjacent to the lamp 250 or directly disposed on the lamp 25〇. on. The sensor 26A is used to sense whether an object is close to the luminaire 250 to cause the control element 24 to adjust the brightness of the luminaire 250. In detail, by the setting of the sensor 26, the illuminator 250 can be set to a relatively dark state to save power. When the sensor 260 senses that an object approaches the luminaire 250, the sensor 260 transmits a sensing signal to the control element .240, after which the control element 240 raises the party of the luminaire 250 to enhance the visibility of the surrounding environment. . In this embodiment, the sensor 260 can be an optical sensor, a thermal sensor, or other type of sensor, which is selected according to requirements. When the object is away from the lamp 250, the control element 240 then lowers the brightness of the luminaire 250 to reduce the use of power. It can be seen from the above that by the setting of the sensor 26〇, 26518twf.doc/p 200933328 can save power and maintain visibility to maintain the safety of passers-by. In summary, the intelligent power saving system of the present invention has at least the following advantages: 1. Using a regenerative energy device and a commercial power supply as a power supply device, and using a switching element as a power supply device, and preferentially utilizing the power provided by the renewable energy device. Therefore, renewable energy can be used effectively, and at the same time, the amount of utility power can be saved. Second, the use of control components to adjust the brightness of the luminaire, because the brightness of the luminaire is proportional to the amount of power required by the luminaire, it can effectively reduce the amount of electricity required for the luminaire. Second, the addition of the f-tester can more effectively reduce the amount of electricity required for the luminaire' to achieve energy-saving purposes. The present invention has been described above with reference to the preferred embodiments thereof, and is not intended to limit the scope of the invention, and may be modified by those skilled in the art without departing from the spirit and scope of the invention.
