Garden Light Wiring Diagram (High Voltage and Low Voltage)

Hi, in this article, we are going to see the Garden Lighting System Wiring Diagram. We will see the connection with a timer also, so the light can automatically get turned on or turned off. We will learn the connection for both High Voltage and Low Voltage Systems. Garden lighting is a great way to make the garden more beautiful and useful after dark. It can turn a simple garden into a magical and inviting space. 

Garden lighting not only helps to make the garden attractive at night but also helps improve safety by lighting up areas like pathways, steps, and corners of the garden. So anyone can move around the garden safely at night and enjoy the natural beauty of the garden. The main purpose of garden lighting is to provide enough light for safety and to highlight special features of the garden at Night or after dark.

When designing the garden lighting system one important decision is whether to use low-voltage or high-voltage systems. Each option has its own advantages and disadvantages which depend on factors like safety, installation requirements, energy efficiency, and cost. 

The Low-voltage lighting operates at 12 volts or 24 volts power supply which is much lower than the standard 120/230 volts of household electricity. It requires a transformer or power adapter to reduce the voltage from the main power supply. Low-voltage lighting systems are much safer to use in gardens because they reduce the risk of electric shock. 

The high-voltage garden lighting system operates at the same voltage as household electricity (120V or 230V, depending on the country standard). High-voltage lighting systems provide strong and bright light which is suitable for lighting large areas but it has a greater risk of electric shock. Here Professional installation is required to handle the higher voltage safely.

Low Voltage Garden Light Wiring Diagram

Here, you can see the Low Voltage(12V DC) Garden Lighting System Wiring Diagram.

Connection Description

1. First of all the main 230V or 120V AC is connected to the input of the main breaker(Here a double pole MCB is used).
2. The output of the breaker is connected to the input of the contactor.
3. The output of the contactor is connected to a power converter (230V or 120V AC to 12V DC). Sometimes a low-voltage transformer is used to step down the voltage.
4. Finally, the output of the power converter is connected to all the garden lights.
5. The coil of the contactor is connected through a timer.

Operation

Power Input and Protection (MCB)

The system starts with the main power supply, either 230V or 120V AC(as per country standard). The 2-pole MCB (Miniature Circuit Breaker) protects the system from overcurrent or short circuits. If there is any electrical fault, the MCB trips and cuts off the power to the whole system.

Automation with the Digital Timer

The digital timer is programmed to control when the garden lights turn on and off. At the preset time (e.g., after sunset), the timer sends a signal to the contactor to start the system. Similarly, the timer turns off the system at the preset "off" time (e.g., at sunrise).

Switching the Power (Contactor)

The 2-pole contactor basically acts as a switch. When the timer sends a signal to the contactor coil, it closes the contactor and allows the power flow to the Power Converter to turn on the lights. When the timer signal stops, the contactor opens and cuts off power to the power converter to turn off the lights.

Voltage Conversion (AC to DC)

Once the contactor is closed, power flows to the AC to 12V DC converter. This converter transforms the high-voltage AC electricity (230V or 120V) into safe, low-voltage 12V DC power required by the garden lights.

Garden Lights

The 12V DC garden lights are connected to the output of the converter. When the converter receives power it supplies 12V DC to the lights.

High Voltage Garden Light Wiring Diagram

Here, you can see the High Voltage(230V or 120V AC) Garden Lighting System Wiring Diagram.

The connection and the operation principle of this high voltage system are the same as the low voltage system just the difference is in the low voltage system, there is a power converter that converts high voltage to low voltage but here no power converters. Here, high-voltage garden lights are used which are directly connected to the high-voltage power supply from the output of the contactor.

Remember that although the wiring system or circuit connection is almost same for the both systems but there is a huge difference in practical installation. The high-voltage system requires more professional installation by professional persons to ensure safety from the high voltage.
