Different Illumination Source

An All-in-one solar street light has an LED fixture as its main illumination source. Traditional solar street lights use metal halide (MH) or high pressure sodium (HPS). Recently, solar street light manufacturers have become competitive with their All-in-one solar street light products and has improved the quality of LED modules.

As a buyer, you have to look out for the brand or type of LED the manufacturer uses. Cree 3030, Bridgelux (3030/5050) or Philips 3030 are usually the best brands for the LED.

A highly efficient LED can not only save tons of energy, but can also last longer as they don’t easily overheat. Whereas before, LED can only sustain up to 100 lumens per watt, now it can reach up to 200 lumens per watt. This can potentially save you a lot from maintenance expenses and sustain better illumination.

Lithium Battery Evolution

Traditional solar street lights used to be sustained by inefficiently-developed lithium batteries. Now, the all-in-one solar street light battery has significantly improved and is currently being developed to store more energy for sunlight-less days. In the past, the working temperature was the main issue.

Lithium-ion batteries used to fail under 0 deg Celsius. But today, it can work up to -30 deg Celsius. Lithium-iron batteries are also used in all-in-one solar lighting technologies and it can work even more flexibly at lower temperatures.

How Does an All-in-One Solar Street Light Work?

The All-in-One Solar Street light works similar to the traditional street light or other types of solar street lights, but it has several special smart features. Here’s how it works.

  1. When the sun rises and the temperature in the area increases, the sensor tells the LED lamp to switch off.
  2. As the temperature further rises, it prompts the solar panel to begin harnessing the sun’s energy. The energy harnessed will then be stored in the battery.
  3. To prevent the battery from overcharging, a smart charge controller will disconnect the battery from the solar panel whenever it’s fully charged.
  4. During the night, the LED light is prompted to switch on. Unlike a normal solar street light that just stays lit the whole night, an all-in-one solar street light does more than that. It has pre-set functions such as automatic dimming, lighting and energy conservation. It’s also made to follow a schedule profile that you can set according to lighting demands in your area.

Here’s a video on how an all-in-one solar street light works.

For HeiSolar, you can easily set these functions so that solar energy optimization and lighting conservation are easily met.

Time Control Function

This function works alongside the microwave motion sensor. With the time control function, you can simply adjust the lighting mode according to the specific hours where traffic occurs in a particular zone.
For example:

  • At 6:00 pm to 8:00 pm (2hrs), there are many people on the streets. You would want to set the brightness at this time of the day at 70% brightness.
  • At 8:00 pm to 10:00 pm (2hrs), the streets are packed with people. You would want to set the brightness at this time of the day at 100% brightness.
  • At 10:00 pm to 12:00 pm (2hrs), there are few people on the streets. You would want to set the brightness at this time of the day at 50% brightness.
  • At 12:00 pm to 5:00 am (5hrs), there are few to no people on the streets. You would want to set the brightness at this time of the day at 30% brightness.

Motion Sensor Control Function

When the motion sensor detects a person on the street at a certain distance, it prompts the LED lamp to increase its brightness. You can easily set the intensity level you think best for your area.
For instance:

  • 100% if people come close
  • 30% far away (Default)
