How many lumens do you need for bright solar lights?

How Many Lumens For Outdoor Landscape Lighting – The best range of lumens for outdoor lighting is 12 to 1,300 lumens. How many lumens you need for outdoor landscape lighting is between 50 and 700. The amount of brightness most people want changes based on location.

How long do solar lights Last?

So how long do solar lights last? – Generally speaking, the batteries in outdoor solar lights can be expected to last about 3-4 years before they will need to be replaced. The LEDs themselves can last ten years or more. You will know that it is time to change parts when the lights are unable to maintain charge to illuminate the area during the night.

  • There are a few adjustable factors that can also affect the lifespan of your outdoor solar lights.
  • For one, their placement in relation to other artificial lighting can diminish or enhance their longevity.
  • Make sure that your outdoor solar lights are placed in direct sunlight at a distance from street lighting or house lighting, as too close of a proximity can throw off the sensors that cause them to kick on in low lighting.

Apart from their location, the cleanliness of the solar panels can also be a factor in solar light upkeep. Especially if you have your lights located near a garden or other typically dirty area, be sure to wipe off the panels every other week so that they get sufficient sunlight.

What is the difference between LED lights and solar lights?

Hello, everyone. In this video, I will use several very simple tools to tell you the difference between LED lamp and solar lamp. Now many friends are not sure what the actual power of 50W solar lamp is. Whether the 50W of most solar lamps can really achieve the brightness of 50W of LED lighting? Today, I have prepared a street lamp with the same appearance to test and analyze for you. Before we start, we should have a clear basic understanding of LED lighting and solar lighting, that is, they are essentially different. LED lighting is the direct power supply of the grid (that is, the voltage we use to connect household appliances), and solar energy is the battery power supply, which needs to be charged. The picture above is a laptop battery with a 95.04Wh in the red circle. What does this Wh mean? W is the unit of energy, W is tile, h is hour. Popularly speaking, the physical meaning of battery capacity is how much charge the battery can hold or release.

  • We often use Ah (ampere time) or mAh (milliampere time) to express it.
  • According to the definition of current: I = Q / t, we know that Q = It, mA (milliampere) in unit time of current I, T represents time, unit hour (time), so our battery capacity unit is mAh.
  • That is to say, if the capacity of a battery is 1000 mAh, and if the current is 100 mA when he works, the power supply can theoretically be used for 10 hours.

But we can see from the formula that Q = It does not involve voltage, so this unit can only show how many coulombs of charge can be contained inside the battery. But it can’t explain how much work this battery can do and what the maximum power it can provide.

  • The working voltage of different types of products is different.
  • So we often see a number in Wh next to mAh.
  • The work W = UIt = UQ and the unit of voltage U* current I is W (watt), so the W in the battery is expressed in Wh, which indicates how much work the battery can do.
  • The voltage of the 6600 mAh battery mentioned above is 14.4V, 14.4 *6600=95.04Wh, and the total work that he can do is 6.6 *14.4 *3600=342144 joules.

Wh is a quantity proportional to voltage, current and time. MAh is usually used as a battery charge and discharge index. It is directly proportional to the charge (discharge) current and time of the battery. To make it comparable or convertible with Wh, it is necessary to know the voltage of the battery. As you can see from the picture above, the connection between the two street lamps is different. The LED street lamp on the left is connected to 220V market power, while the solar panel on the right is connected to DC power supply. Now I’ll take the two lights apart and have a look at the internal structure. As you can see from the picture above, the two street lamps look exactly the same in appearance, and the internal structure is totally different. The LED street lamp on the left is powered by an LED driver, while the lithium-ion battery on the right. Let’s take a step-by-step analysis of its internal composition, starting with the led light source. Above are two kinds of LED light sources for street lamps. As you can see, they all have the same appearance. So what’s the difference? Let’s take a look at the lower left corner of the LED light source. You can see the sign on the left is: 50C3B (50 strings 3 parallel), and on the right is: 150B1C (150 strings 1 parallel) which represents the voltage and current of the lamp chip. It is well known that in parallel connection, the voltage is constant and the current is added; in series connection, the current is constant and the voltage is added.

  1. The normal 1W LED lamp c to have a voltage of 3.2V and a current of 300 mA.
  2. The rated power of this LED street lamp is 50W.
  3. From this, we can deduce that each packaged chip of this light source is about 0.3W.
  4. At the same time, we can also know that the current of each packaged chip is about 100 mA.
  5. In the first case, 50C3B, the output current is about 300 mA and the voltage is about 150 V to light the light source.

In the second case, 150B1C, the output current is about 15 000 mA and the voltage is about 3.2 V. So the power is equal to the current multiplied by the voltage, so we can now calculate the actual power of this LED street lamp is about 45W. From the light source point of view, both lamps use 50W LED light source, but change the way of packaging, so that the voltage and current of the driving light source have changed. Above are the internal components of two street lamps. On the left is the LED driving power supply, and on the right is the lithium-ion battery. Let’s start with the driver section: Driving Power Supply of LED Street Lamp You can see the electrical parameters in the red ring: the output voltage is DC150V-170V, and the output current is +300mA, which is also consistent with the bulb voltage and current we calculated before. Let’s look at solar street lamp batteries: From the figure above, we can see clearly that the lithium-ion battery model is 32560, the capacity is 18Ah, and the voltage is 3.2V. Then the physical capacity of the battery pack is: 3.2 times 18Ah equals 57.6Wh. In theory, the battery pack can provide 57.6W solar light for up to an hour. As you can see from the picture above, there are three parts in the interior of the solar lamp: light-controlled and power-adjusted PCB board, remote sensing head and lithium battery pack. We will focus on the optical control and power-regulating PCB board.

  • This component can explain the question we raised above: “Why do many manufacturers claim that solar lights can be on for five to seven rainy days? This PCB board can realize the controllable power output of solar cells.
  • What does that mean? That is to say, the circuit board can adjust the output power of the solar lamp at different time periods to ensure that the lamp is on for a long enough time.

For example, if our solar lamp lights up at 7:00 p.m., we can achieve a brightness 20% higher than that after 10:00 in the period of 8:00-10:00 crowds, and then decrease the brightness to save the battery power and achieve longer lighting. Believe to see here, everybody understands why the solar lamp can last for 5-7 days. As you can see from the naked eye in the picture above, the brightness of the LED street lamp is much higher than that of the solar street lamp. At the same time, you can also see the reading on the power tester. This picture is not obvious enough. Let’s look at the following one. In the figure above, you can see that the input voltage is 237.2V, the output current is 338mA, the power is 43.69W, and the power factor is 0.55 (that is 55%). These data basically accord with our calculation results. Below is a comparison of the brightness of LED street lamp and solar street lamp. The brightness of LED street lamp is about 1460 Lx. The brightness of solar street lamps is about 198Lx. From the above two comparisons, the brightness of the solar street lamp is much lower than that of the LED street lamp. Although the test equipment is relatively simple, we can also see the difference from the test results. All right, I’ll share the above with you today. I hope it will be helpful to you.
