Description

Technical Field

[0001] This utility model relates to commonly used control electrical appliances in industrial production, specifically to a fully automatic street light and community courtyard light energy-saving controller, belonging to the field of low-voltage electrical appliances. Background Technology

[0002] Streetlights and courtyard lights are essential public facilities that people rely on every day, especially in cities where they are mandatory. However, many streetlights and courtyard lights remain on all night, from dusk till dawn, wasting a significant amount of electricity – a highly unreasonable phenomenon. As we all know, for thousands of years, people have generally lived by working at sunrise and resting at sunset, meaning that nighttime is when most people go to bed. Of course, some people, for various reasons, cannot return home immediately after dark, making streetlights crucial for their convenience. However, after midnight, there are very few pedestrians and vehicles on the road, yet streetlights and courtyard lights remain 100% lit – clearly an unnecessary waste.

[0003] Another point is that some streetlights or courtyard lights are equipped with time-controlled switches to automatically control their on / off times. However, the time settings are quite simplistic. Most are set according to the time of nightfall and sunrise in winter. For example, the streetlights turn on at 6:30 pm and turn off at 6:30 am the next day. This setting is definitely unreasonable.

[0004] As we all know, in a year of 365 days, except for the winter and summer solstices when day and night are of equal length, the rest of the time the daylight hours change linearly with the passage of time. The summer solstice in the Northern Hemisphere has the longest daylight hours, while the winter solstice has the shortest. Therefore, fixing the on / off time of streetlights to a fixed point is clearly unreasonable. Most regrettably, on a bright summer evening at 6:30 pm, many streetlights automatically turn on, and by morning, when it is already quite bright, they are still on. This waste of electricity is heartbreaking.

[0005] We shouldn't underestimate the small amount of electricity wasted by just a few streetlights. The key is that when the number is large, it becomes a significant figure. Consider this: in our country alone, how many streetlights and residential lights provide illumination every day? The combined effect of these instances of wasted electricity is enormous. Therefore, saving energy on streetlights is no small matter, especially given the global push to peak carbon emissions and meet carbon emission standards. Solving the energy-saving problem for streetlights and residential lights is therefore of paramount importance. Summary of the Invention

[0006] This utility model provides a fully automatic energy-saving controller for streetlights, community lights, and courtyard lights to overcome the drawback of wasting electricity.

[0010] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0011] 1. Inside the chassis (12), an air switch (1), a light control module (2), a contactor A (3), a time control switch (5), a contactor B (6), and a step-down module (7) are installed. The upper end of the light control module (2) is electrically connected to the L terminal of the lower side of the air switch (1), and its lower end is electrically connected to the neutral line N. The upper end of the contactor A (3) is electrically connected to the F terminal of the light control module (2) through the normally closed contact J2-F of the contactor B (6), and the other end is electrically connected to the upper end of the time control switch (5). The upper end of the contactor B (6) is electrically connected to the output terminal E of the time control switch (5). The power input terminal R of the step-down module (7) is electrically connected to the left side of the air switch (1) and the normally open contact J1-1 (4) of the contactor A (3) through the normally open contact J2-1 (8) of the contactor B (6). The output terminal (E) of the step-down module (7) is electrically connected to the lower end of the normally open contact J2-2 (9) of the contactor B (6) and the upper end of the electric fan (11). The upper end of the normally open contact J2-2 (9) of the contactor B (6) is electrically connected to the right side of the normally open contact J1-1 (4) of the contactor A (3) and the output terminal P1.

[0012] When a fully automatic street light and courtyard light energy-saving controller is connected to the mains power and the controlled street light, the controller automatically enters the working state. When the outdoor light dims to a certain level, the F point of the light control module (2) flips from low level to high level, the contactor A (3) is energized and enters the energized state, the normally open contact (4) J1-1 of the contactor A (3) closes, and the street light (13) is energized and lit.

[0013] When the F point of the light control module (2) flips from low level to high level, the time control switch (5) also enters the standby state. At this time, the time control switch (5) will control the street light to enter the midnight light time according to the time set by people. For example, we set the time of the first output instruction of the time control switch to 0 o'clock, the time of the second output instruction to 9 o'clock the next day, and enter the automatic operation state.

[0014] When the time reaches 0 o'clock, the output terminal E of the time control switch (5) changes from low level to high level, the contactor B (6) is energized and closes, its normally closed contact J2-1 is opened, and its normally open contact (4), namely J1-1, returns to the open state, and the line from the street lamp 13 directly to the air switch 1 is cut off. At the same time, the normally open contact (8), namely J2-1, of the contactor B (6) is turned on, the step-down module (7) and the air switch (1) are turned on and start to work. At the same time, the normally open contact (9) J2-2 connected in series between the output terminal E of the step-down module (7) and the street lamp (13) is turned on. At this time, the entire street lamp is controlled by the step-down module (7). Assuming that the output voltage of the step-down module (7) is 110V, the entire street lamp will become half-lit and enter the power-saving state, which is the so-called midnight light state.

[0015] When the weather brightens to a certain level the next day, the light control module will automatically turn off, and the system will automatically return to its initial state, thus achieving the purpose of saving power.

[0016] The invention and implementation of a fully automatic street light and community courtyard light energy-saving controller not only saves a lot of electricity bills for users, but also saves a lot of energy for the country, and saves labor costs. This is beneficial to both the country and users. After the project is implemented, it has high economic and social benefits.

[0017] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the spirit of the invention should fall within the protection scope defined by the claims of the present invention.
