How to calculation the LED strips power?
The power (Watts) is divided into theoretical power and actual power:When we calculate the theoretical power, we only need to know the power of the single SMD and then multiply it by the number of lights. With 5050 SMD 60pcs per meter LED strips, the power per meter is 14.4W, it is because, 5050 SMD single SMD watts 0.24W x SMD quantity number 60LEDs = 14.4W / M; conventional 3528 SMD power is 0.08W, 2835 SMD The power is 0.1W or 0.2W, and other SMD models are: 3014, 5630 and so on. For a detailed description of the SMD model, please see the connection: https://rolllights.com/smd-led-sizes
The actual power (Watts) means that the power of the LED strips made by the real thing is much smaller than the theoretical one. For example, the 5050 SMD 60pcs LED strips per meter has a theoretical power of 14.4W, which is only about 12W. If it is 2835 SMD 120pcs, the theory The power is: 0.2W x 120 = 24W, but it is only about 14W.
Why is there a difference between theoretical power and actual power?
There are two reasons: maintaining 80% of the power of the LED strips can greatly increase the life of the SMD; in addition, in order to better improve the luminous efficiency, the heat energy is converted into light energy to the greatest extent. When the flexible LED strips is 24W per meter, it must consider its heat dissipation problem. The usual way to dissipate heat is to attach a blue backing to the back of the strip and attach it to the aluminum profile to help dissipate heat.
General LED strips power per meter:
|SMD type||SMD per M||Voltage||Watts / M|
|5050 4in1||60 SMD/M||12V/24V||18W|
|5050 4in1||84 SMD/M||12V/24V DC||24W|
|5050 5in1||60 SMD/M||12V/24V DC||20W|
|5050 5in1||96 SMD/M||12V/24V DC||28W|
How to choose the right power source according to the watts of LED strips?
First, must choose the right voltage. The 12V LED strips should be equipped with a 12V input power supply. In addition, according to the actual power of the LED strips plus 20% to select the appropriate power supply: for example, 5M 5050 SMD 60pcs per meter light bar, one meter power is 12W, It is equipped with: 12W x 5 x 1.2 = 72W. The need to pay attention to this is to match the power supply according to your own installation scenario. If the total power needs to be 350W, but because the installation is not convenient, it is recommended to choose 2-3pcs small wattage power supply for easy install.
Can I get a quotation with provide led strip watts?
In fact, only provide LED strips request wattage is not enough to quote. Take the 7.2W LED strips as a comparison, customers generally have the following options:
3528 120led per meter
2835 60led per meter
5050 30led per meter
It is not difficult to see from here that different SMD models, different quantity can make the same wattage. The highest price in this is: 3528 120led per meter; the most cost-effective is: 2835 60led per meter, and their brightness is similar, 2835 60led per meter will be a little brighter.
The higher the wattage, the brighter it is?
In theory, the higher the wattage, the brighter the LED strips. But the brightness is not only determined by the wattage. So what are the factors that determine brightness? The brightness is also related to the number of SMD per meter, indicating the size of the SMD chip and the color temperature. Therefore, the wattage is not the only determinant of brightness. On the contrary, the number of wattages of the LED strips should not be more than the normal wattage. As mentioned above, the wattage is too high and the heat dissipation is not good, which will affect the service life of the LED strips.
Ways to increase brightness:
Frequent customers will ask us: Can you do 39W or 48W? In fact, there are many ways to increase the brightness. The biggest advantage of LED is not only environmental friendly, but also there is one point: energy saving. We really don't need to make bigger wattage products to increase brightness. At present, our company has made a high-brightness LED strips. The luminous efficiency of the normal LED strips is: 100-110LM/W. Our product can achieve 160-170LM /W.
Its luminous efficiency is 172.6LM/W, which is indicated as 80.
That is to say, in the LED strips with normal brightness of 100-110LM/W, do 28W brightness: 28W x 100LM =2800LM, but if you use our high LED strips 172LM/W, as long as 2800LM / 172LM = 16W or so. Really achieved high brightness, energy saving and long service life.
