The system does not need to use external equipment, such as a photocell, an NEMA base, a modem, a control / monitoring center or an internet data network service, so that the system becomes an innovative technology with greater advantages, specific faults and implementation cost caused by no need of external accessories are reduced, and economic benefits and energy conservation are further maximized.

Description

Technical Field

[0001] This utility model belongs to the technical field of control systems, and in particular relates to an electronic control system for LED street lighting. Background Technology

[0002] Currently, public lighting fixtures used in cities and roads are connected to external devices to enable better control and efficiency improvements, thereby reducing costs and saving energy.

[0003] Current technologies include remote management, adding communication and control modules via wireless internet, radio frequency, etc., to the phototube base in the lamps to control and monitor them, and enabling this communication through concentrator links to transmit it to the power plant. This means additional investment in installation and operation, with additional hidden costs not being seen until the medium term. Therefore, the actual benefits are not as expected, resulting in overinvestment that is higher than the cost of the lamps themselves. Utility Model Content

[0004] The device proposed and intended for protection in this application is an electronic control system for LED street lighting. This system is programmable, uses LED luminaires, and can achieve different times and levels of illumination, dimming, and extinguishing, following a specific schedule and taking seasonal changes into account. Integrated into the driver, it employs GNSS, GPS, or other geolocation systems, has a built-in antenna to receive satellite signals, includes a real-time satellite clock, and optionally a light sensor, enabling it to operate autonomously and follow user-preset programs. It does not require external equipment such as photovoltaic cells, NEMA bases, concentrator modems, or data network services.

[0005] It is important to note that the electronic control system described in this application is not a telemetry or remote management system; it only utilizes open one-way signals from geolocation satellites to acquire time and geographic location information. This information allows for the precise setting of on / off times to optimize LED public lighting services, reduce power consumption, and extend their lifespan. Eliminating the need for components such as photovoltaic cells and their mounting bases reduces the risk of failure and system implementation costs, thereby maximizing the service provided.

[0006] The advantage of this invention is that the installation of lamps using this unidirectional driver is very simple, requires no user intervention, is completely autonomous, and is very economical in the medium to long term.

[0007] The details of this innovative electronic control system are described below, as shown in the description and accompanying figures. Attached Figure Description

[0009] Figure 2 This is a schematic diagram of the present invention. Detailed Implementation

[0010] This utility model provides an electronic control system for LED street lighting, the system comprising:

[0011] The electronic real-time geolocation module can receive GNSS / GPS positioning information and real-time local time via satellite link and with the help of an integrated antenna;

[0012] The antenna, used for connecting to satellite networks, is integrated inside the device and receives time and location information from geolocation satellites in a one-way open manner.

[0013] The memory will store information about sunrise and sunset times based on geographical location, and through non-volatile memory, the information can be retained even when the power is interrupted;

[0014] The microcontroller, as the central processing unit of the device, receives all information from the geolocation / real-time time module, antenna, memory, light sensor and bus interface. The information includes data uploaded by the user / manufacturer. The microcontroller automatically sends the necessary commands to the LED driver circuit to perform the functions of turning on, turning off and dimming, and provides real-time location information.

[0015] A light sensor can be integrated inside the device or connected to the outside of the luminaire via a cable.

[0016] This electronic control system, which can be integrated into LED luminaire drivers, has the following innovations:

[0017] The electronic control system integrated into the drive unit has the function of automatically identifying the geographical location and local real-time time of the LED street light, and uses GNSS, GPS or other geolocation technologies to receive satellite information in conjunction with the built-in satellite antenna.

[0018] As needed, an electronic light sensor can be selectively integrated to control the forced activation of lighting fixtures based on factors other than local day and night times, such as weather and fog.

[0019] Implement software with intelligent algorithms inside the microcontroller to perform functions and decisions in an intelligent and autonomous manner (without relying on remote communication with the user or central control), including turning on, dimming, turning off, positioning, date and time (recognizing geographic coordinates, season and time).

[0020] Utilizing existing hardware technology, the lighting attenuation level is controlled through pre-programmed, user-determined events, operating precisely based on satellite-acquired location and actual time (without using an internal hour counter, as this would introduce offsets due to annual variations in sunrise and sunset times). The time and date data used is acquired directly from the satellite. This data is obtained in real-time via satellite, requiring no intervention from the user or monitoring center.

[0021] The advantage of this invention is that the installation of lamps using this unidirectional driver is very simple, requires no user intervention, is completely autonomous, and is very economical in the medium to long term.

[0022] This application includes a system block diagram (Figure 1), which details the control system.

[0023] The complete device can be integrated with certain existing drivers on the market and is suitable for the assembly of LED technology lighting fixtures. It maintains updated time and location information by connecting to open satellite network signals, and updates automatically each time the lighting fixture is turned on from the grid or at preset time intervals (Figure 2).
