How Do You Use A 1W LED PCB?
1W LED PCBs have a high lumen output per watt efficacy and this makes them suitable for home lighting, office interior, and various appliances.
Anyone can easily implement and wire a 1W LED PCB as they have two terminals, a negative and positive terminal.
All you need to do is connect these two terminals in the right polarity to a 3.3-volt direct current [DC] source.
For optimal brightness, you should rate the DC source to around 1 ampere.
Besides, the voltage is not a fixed requirement as it may vary between 3 volts and 3.5 volts, but should not surpass 3.5 volts.
Also, you can obtain a DC source from the following:
- Standard 3 volts and 1 ampere SMPS adapter units
- 3 volts and 1 AH [ampere hour] batteries
- A transformer power supply that is home built
However, you should take care of one thing when using 1W LED PCBs, that is, the current should not surpass 350mA.
This means the 1W LED PCB will operate effectively when the voltage is equal to or below 3.5 volts.
Therefore it means the DC source should contain built-in voltage regulators.
The voltage regulators will maintain a constant voltage between 3 volts and 3.5 volts.
Besides, there are instances you may have crude, unregulated power supply sources whose voltage surpass the 3.3-volt threshold.
In such a scenario, use calculated resistors in a series configuration with the 1W LED PCB to ensure it operated optimally.
What Colors Do 1W LED PCBs Come In?
1W LED PCB with different colors
These lights come in various colors such as:
- Red 1W LED PCB
- Blue 1W LED PCB

- Green 1W LED PCB
What Is The Purpose Of Heatsinks In 1W LED PCBs?
1W LED PCBs emit intense lights meaning they get extremely hot in a few seconds.
When the heat level exceeds 100 degrees Celsius, these devices will permanently get damaged.
This feature means you should fit heatsinks at the base of 1W LED PCBs to assist in dissipating the heat that these lights generate.
Instead of mounting heatsinks, you can opt for heatsink-based 1W LED PCBs to perform the same task.
Dissipador de calor em LED PCB
Why Are 1W LED PCBs Popular?
1W LED PCBs are popular as they generate intense light with minimum power consumption, and are highly advanced than conventional lighting systems.
How Does A 1W LED PCB And 5mm LED Compare?
1W LED PCBs are similar to standard 5mm LEDs that are common in devices such as DVD players, television sets, music systems, etc.
The difference between 5mm LEDs and 1W LED PCBs lies in the current [Ampere] specification.
Standard 5mm LEDs, or even 3mm LEDs, need a current of about 10mA to30mA while a 1W LED PCB will need a current of about 300mA.
However, when you consider the voltage they require, it is fixed at about 3.3 V for both of them.
To produce a high-intensity beam of light, 1W LED PCBs require 3.3 volts with a current of about 300mA.
This light is very intense and may damage your eyes permanently, or partially blind you, when you look at them directly for a long duration.
How Does 1W SMD LED PCB And 1W COB LED PCB Compare?
1W COB LED PCB
Veja como esses dois se comparam:

Besides, SMDs also improve thermal connections on the PCBs.
- 1W COB LED PCB
Chip a bordo [COB] is the recent advancement in LEDs that use chips containing several diodes, numbering 9 or more.
Besides, COB technology has no casing thereby the light array of this LED will be dense than SMDs.
Also, they emit consistent beams of light with no visible individual point of light hence offering superior optics.
1W COB LED PCBs have more lumen per watt ratio than other technologies of LEDs like SMD or DIP.
Besides, COB technology offers suitable conditions for optimal cooling which enhance the efficiency and longevity of the lamps.
What Are The Layers You Can Find In 1W LED PCB?
1W LED PCBs contain many mechanical layers but you require one mechanical layer to assemble the board.
The mechanical layer will also outline the configuration of the printed circuit board.

However, the texts are vital when you are debugging 1W LED PCBs in laboratories.
For instance, locating R1 text assists you in finding the potential of single terminals of the R1 resistor.
When you have no texts, you need to refer to the original design.
Also, you can print blank boxes which enable one to revise and place serial numbers with sharpies or through stamping.
You can modify power and ground planes to have many copper sections with varying potentials.
Besides, they will enhance the convenience of the planes.
For example, the split plane can allow the board to pass several voltages on varying sections of the board.
Camada de pasta de solda
This is the layer that you will use to mount surface components on the printed circuit board.
The solder paste layer is important when you plan to mount several components on the board.
The solder paste enables the solder to flow effectively when sticking the parts on the PCB.
