[0017] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0018] The following first explains the names involved in this application:

[0019] Solar controllers are mainly used in off-grid solar power generation systems. They can automatically control the charging and discharging of batteries by multiple solar panels, coordinate the work of solar panels, batteries, and loads, monitor the charging status, and display the current, voltage, and battery status of the solar panels charging the batteries. They can effectively prevent overcharging of the batteries and have reverse connection and short circuit protection functions. Solar controllers need to coordinate the work of solar panels, batteries, and loads to ensure the stable operation of the entire off-grid solar power generation system.

[0020] D4i (DALI for Intra-Luminaire, DALI in lamps) is a standard for smart IoT lamps. D4i is an extension of DALI-2 certification, adding support for data-related functions on the basis of DALI-2. D4i is built on global standards and focuses on interoperability between equipment from different manufacturers. D4i defines a unified communication interface and data format so that lamps and sensors produced by different manufacturers can be compatible with each other, thereby achieving interconnection between lamps. The D4i standard supports the collection and analysis of data such as lighting assets, energy and diagnostics, which is a function not available in DALI-2. Through the D4i standard, sensors and communication modules can be easily integrated into LED lamps without the need for additional DALI lines. This integrated approach can provide more efficient and precise lighting control, while also helping to save energy and increase the life and reliability of lamps.

[0021] like Figure 1 As shown, Figure 1 The solar lamp with controller based on D4i communication provided by the embodiment of the utility model comprises: a D4i module 100, a photovoltaic panel 200, a solar controller 300, a battery 400 and a lamp 500; the photovoltaic panel 200, the solar controller 300 and the battery 400 are electrically connected in sequence, the solar controller 300 is also electrically connected to the D4i module 100, and the D4i module 100 is electrically connected to the lamp 500; the D4i module 100 is signal-connected to the photovoltaic panel 200 and the battery 400 respectively;

[0022] The photovoltaic panel 200 is used to convert solar energy into low-voltage direct current electricity;

[0023] The solar controller 300 is used to boost the low-voltage DC power to high-voltage DC power and then reduce the voltage to constant-voltage DC power; to provide the constant-voltage DC power to the battery 400 for charging, and to stop charging the battery 400 when the voltage of the battery 400 rises to a set voltage; and to provide the D4i module 100 with the constant-voltage DC power output by the battery 400;

[0024] Specifically, the solar controller 300 controls the photovoltaic panel 200 to charge the battery 400, and manages the discharge process of the battery 400 to the D4i module 100. It ensures that the battery 400 will not be damaged due to overcharging or over-discharging, and provides stable power output according to the needs of the D4i module 100.

[0025] The D4i module 100 is used to read the power generation data of the photovoltaic panel 200 and the charge and discharge data of the battery 400, and control the lamp 500 using the DALI dimming mode.

[0026] Specifically, the existing technology uses a high-voltage power supply from the mains, which is affected by the mains power supply, has the risk of power outages, and can only read the mains data; the present application provides a constant-voltage DC output power supply through the solar controller 300, which is not affected by the mains power supply and can provide a stable power supply guarantee. In addition, the D4i module 100 of the present application can read the power generation data of the photovoltaic panel 200 and the charge and discharge data of the battery 400, which is convenient for autonomous and controllable power supply management; the conventional solar controller 300 uses the PWM dimming mode, and the D4i module 100 of the present application uses the DALI dimming mode, which has a better dimming effect and more precise control;

[0027] The solar lamp with controller based on D4i communication provided by the present application, by integrating the solar controller 300 and the D4i module 100, has opened up the last mile of solar street lamp networking control. The sensor that meets the D4i standard can take over the lamp 500 that meets the D4i standard and control the lamp 500, without any concerns about compatibility and Internet of Things security. The present application improves the compatibility and security of solar street lamp networking.

[0028] In some embodiments, the solar lamp controller further includes a D4i sensor 600 , which is connected to the D4i module 100 via a DALI bus signal. The D4i module 100 is used to receive and process the DALI control signal sent by the D4i sensor 600 .

[0029] Specifically, the D4i sensor 600 is designed using the D4i standard to facilitate seamless integration into the LED lamp 500. The D4i sensor 600 can directly receive and process DALI control signals through the DALI bus.

[0030] In some embodiments, the D4i module 100 is also used to send the power generation data of the photovoltaic panel 200 and the charge and discharge data of the battery 400 to the D4i sensor 600 .

[0032] In some embodiments, the voltage of the constant voltage direct current is 24V.

[0033] In some embodiments, the solar controller 300 is an MPPT solar controller 300 or a PWM solar controller 300 .

[0034] It should be noted that the MPPT (Maximum Power Point Tracking) solar controller 300 and the PWM (Pulse Width Modulation) solar controller 300 are both key components in solar power generation systems for optimizing battery charging and improving system efficiency. The MPPT controller monitors the output voltage and current of the solar panel in real time, tracks and operates at the maximum power point to maximize the output power of the solar panel. It is suitable for large solar power generation systems or when the solar panel voltage does not match the battery voltage. The PWM controller controls the charging process by adjusting the pulse width of the voltage and current output by the solar panel to ensure that the solar panel charges the battery with optimal efficiency. It is suitable for small solar systems, especially when the voltage of the solar panel matches the battery voltage and the budget is limited.
