Solar street lights support time-based dimming. Through the solar street light controller, users can set different lighting time periods according to their needs and adjust the brightness output within each time period. This function is mainly achieved through the controller's time control function, adjusting the brightness of each time period according to actual needs.

In addition, some new controllers also support multi-time control, allowing users to set the luminous power of lamps in different time periods according to actual needs. This flexibility enables solar street lights to use energy more efficiently and meet different lighting needs.

1. Implementation of time-based dimming

(1) Built-in intelligent MPPT controller

Time control: automatically adjust the brightness during the preset time period, for example:

18:00-21:00: 100% brightness (peak traffic)

21:00- 0:00: 60% brightness (energy-saving mode)

0:00-6:00: 30% brightness (second half of the night safety lighting and morning transition)

Light control + time control dual mode: based on the comprehensive judgment of ambient light (dusk/dawn) and time.

You can also set the induction mode in the second half of the night according to project requirements: 30% brightness when no one is around, and automatically adjust to 60% brightness when someone is around.

(2) Remote intelligent management (high-end model)

4G/NB-IoT Internet of Things: Remotely set the time-sharing strategy through mobile phone APP or cloud platform.

In addition: Solway has launched the latest Internet of Things technology, using a dedicated Dali controller. Users can directly connect to the local DALI system through the Zhaga interface for unified management. This technology is widely used in Europe, the Middle East, and parts of Southeast Asia and Africa where there are local DALI system management. If you have project requirements in this regard, please contact our sales for further details!

2. The core advantages of time-sharing dimming

Energy saving: Reducing the brightness during the rest period at night can reduce energy consumption by about 50%, thereby extending the backup time.

Extending battery life: Avoid deep discharge of the battery (especially suitable for lithium batteries).

Reducing light pollution: Reducing the brightness in residential areas after midnight not only provides a certain degree of safety at night, but also meets the current global environmental protection requirements.

3. Customer FAQ

Q1: Will dimming affect the lighting effect?

Reasonable setting of time periods and brightness ratios (such as reducing to 30% in the second half of the night) will have no impact on road safety and avoid glare.

Q2: Can dimming be done normally on rainy days?

Yes, the dimming logic prioritizes basic lighting (minimum brightness), and non-essential functions will be automatically turned off when the battery is low.

Q3: How to customize the time period?

1. The manufacturer sets the settings when making the goods (operated by professional technical installers), and the customer installs and uses it directly when receiving the goods. The customer does not need to operate, which is simple and convenient.

2. The customer uses a computer/mobile phone to adjust according to actual needs, which is suitable for remote IoT intelligent management.

5. Purchase suggestions

Basic requirements: Optional PWM controller for conventional solar street lights (supports 2~3 time period presets).

Basic requirement 2: Optional MPPT controller, which is more advanced than PWM. Supports 3 time periods and above presets. At the same time, MPPT can monitor and track the maximum power point of solar panels in real time, significantly improving the power generation efficiency of the system and accelerating the charging time.

High-end demand: optional 4G/IoT intelligent control, suitable for smart city projects.

High-end demand 2: optional D4i (DALI controller)

Tips to avoid pitfalls:

Confirm whether the dimming gear is smooth (inferior products may have sudden changes in brightness).

Require suppliers to provide dimming test related videos before shipment.

Summary:

The time-sharing dimming function of solar street lights is already an industry standard, which can not only meet lighting needs, but also maximize energy efficiency. Choose the appropriate solution according to the project budget and intelligence requirements.
