Why should i choose 48VDC lighting system solution

A 48V lighting system could be the solution to your problems like voltage drop and too much wiring during outdoor landscape ultra long illumination or indoor large scale bright illumination
Do we really need 48V LED strips for your LED project?
Voltage drop is a common problem when installing long runs of LED strips. There are many ways to solve this problem: wire sizes, parallel connections, amplifiers/power repeaters, etc. But now more economic way simply choosing the right LED strip voltage 48V can save our time and money.
For projects where we need longer runs of lights, 48-voltage DC lighting system could be the solution, they are less susceptible to voltage drop, meaning we can connect longer lines of lines without needing an amplifier or parallel wires.
How 48VDC strip lights reduce the effects of voltage drop?
LED chips are wired in series into groups. Each group contains some LED chips and a resistor. Every section has a certain amount of resistance to electricity being pushed through it. The longer the combined sections get, the bigger the resistance (and the voltage drop) gets. Eventually, it gets large enough to impact the LED brightness. When the voltage gets doubled (24V to 48V), the current is halved, which causes the voltage drop to be reduced by half as well.
48V DC light fixtures suffer from less wasted energy. LEDs use such a small amount of energy that this doesn’t add up to much for small installations. But, the difference in power usage can become significant for commercial installations. Commercial installations also require a larger amount of wires and connectors, a 48V LED light bar or a 48V LED light strip system can get away with half of the electrical conductor requirements.Like wire gauge can be smaller as well.
IC design:
A stable circuit is very important to guarantee good quality of led strip lights, adding IC design can steady current to protect the circuit
3oZ PCB:
The thickness of a led flexible strip PCB is often 2oz and 3oz selectively and the width is designed as 8mm,10mm, or 12mm. The thicker, the better heat dissipation, and the longer life span. The constant current 48V led strip used 3oz PCB.
A thicker layer of copper means electricity can flow through more easily (less electrical resistance). This will create less voltage drop and allow longer runs.
It will also dissipate heat more quickly. The LEDs will stay cooler, which will ultimately help to maximize their lifespan.
The amount of copper in an LED strip is usually measured in ounces per square foot. Typical values for an LED strip are 1oz-4oz. Higher power requires more copper.
Once we have an application that requires long runs of strips, it may be a good idea to use a 48V LED strip. But even 48V LED lights have a limit. we may have to use other techniques to stop our LEDs from fading at the end. For example, using one of our amplifiers.
Frequently asked questions
Q: Do all LED strip lights have a voltage drop?
A: All low-voltage LED strips, such as 12V, 24V, or 48V DC LED lights, will have a voltage drop. Because for the same power consumption, the lower the voltage, the bigger the current. According to Ohm’s law, voltage equals resistance multiplied by current. The resistance of a conductor is constant. The greater the current, the greater the voltage drop. This is also the reason why people use high voltage to transmit electricity.
Q: What can I do to avoid voltage drop on my 48V DC light fixtures?
A: Divide long runs of LED strip lights into shorter strips, then connect additional “Parallel” wires from the power supply to each new LED strip. This process can be repeated as many times as needed as long as the power supply can handle the LED strips total wattage consumption.
Q: How does voltage drop affect 48 Volt LED strip lights?
A: A voltage drop on our 48V light basically means a loss of brightness towards the end of the LED strip. Less than the minimum current can cause an LED to flicker, operate less brightly, or shift in the color.
Q: Why do we develop extra-long 48v led strip lights?
A:With the LED technology development and we seek higher-quality lighting effect, now these 48V SMD led strip lights are highly recommended by lighting engineers and lighting designers
Lighting designers use the extra-long 48v led strip lights to create innovative shape lamps and ultra-long led strip lighting without voltage drop.
More and more companies like Tridonic/XAL/Signify/Osram promote their 48V lighting system and 48-volt lights,the related 48V power supply,48VDC color controller system.
Q:What is the constant current 48V led strip?
A:The 48V led strip light is a led strip built-in constant current IC components (diodes), Working with constant current under the input voltage fluctuates within a certain range, solved the constant voltage led strip’s voltage drop problem and can run 50M max length.
Q:How to cut, connect, install and power 48V LED Strip Lights?
Q.1How to cut 48V led strip lights?
A.1:48V led strip just like 12v,24V led strip,can be cut,cutting line on the dc 48v led strip light, then use a scissor to cut it ,our 48VDC is 10cm cut unit.
Q:How to connect the 48V LED Strip Light by electric iron welding?
1.Prepare the two 48V led strips you need to weld and align the welding points on the same line.
2. Heat the iron to 350 degrees Fahrenheit.
3. Stick a bit of solder on the iron
4. Put the tin wire on the solder joints, and put the soldering iron on for 1-2 seconds.
5. Solder tin on both ends of the strips
6. Align the two ends of the soldering points and put the iron on them for 1 second to 2 seconds
7. After finishing welding, wait for it to cool.
Q:How to install the 48V led strip?
A:
1.Cut off the power supply before connection.
2. Tear off the back adhesive from the connection point in turn and stick it to the installation position of profiles or your applications.
(Please pay attention do not tear off the adhesive tape on the back of the strip light at one time,section by section.)
3. Connect the cables of the 48V led strips with the power supply.
4. When finished sticking and cables connection, then turn on the power supply.
Q:How to connect the 48V led strip with the power supply?
A:The commonly led strip VS 48VDC led strip:
Compared with DC12V and DC24V led strips, the 48V led strip driven by a power supply is enough, even 50m, also just need to connect the driver at one end
Q:What do we benefit from a 48V led strip?
① Max length is 50m driven by single end power supply, can satisfy your choice of all lighting lengths, fewer drivers, less wiring, faster installation, and less installation cost.
②Compared to the constant voltage led strip, the 48V led strip is driven by a constant current, with no voltage drop problem, and the brightness of the strip is uniform from one end to another end.
③3oz PCB and with 3M heat dissipation backing tape, good heat dissipation function, less lighting degradation, longer lifetime.
⑤ultra long-running, less cut, and less soldering,convenient for electrician installation,electrician like 50m package.
