  • The current passing through the LED is between 300mA to 350mA with the maximum absolute forward current being 350mA.

What Is The Purpose Of Using 1W LED PCB?

Here are some cases to consider when you need to understand the purpose of 1W LED PCBs:

  • Luminous outputUsing a 1W LED PCB is suitable for applications that need a high light output within a small system.5mm LEDs offer a considerable light intensity but that does not meet conventional lighting needs.

    Besides, it will be troublesome when you consider stacking them up on one another.

  • Power handling1 watt LED PCBs have mounting facilities for heat sinks.This feature allows the 1W LED PCBs to dissipate heat and handle 1W power effectively.

    Besides, the standard 5mm LEDs do not come with heat sink mounting features, enabling them to burn out when the current exceeds the normal value.

  • Power saving1 watt LED PCBs have a high luminous output per watt than other conventional lighting systems such as incandescent lights.This feature means you will save a lot of power when you use lighting systems that have 1W LED PCBs.

  • Sign and channel letters
  • Cove lighting
  • Edge-lit sign
  • Architectural detail
  • Mini-accent

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

1W LED PCB with different colors

These lights come in various colors such as:

  • Red 1W LED PCB
  • Blue 1W LED PCB
  • White 1W LED PCB
  • Yellow 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.

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?

5mm LED

5mm LED

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?



Here is how these two compare:

    Surface Mounted Devices [SMD] are a new generation of lighting LEDs.
    Most of the LEDs contain SMD chips enabling the LED to be brighter than old generation LEDs.
    The 1W SMD LED is directly soldered on the printed circuit board meaning you require minimal space.
    Besides, SMDs also improve thermal connections on the PCBs.
    Chip on Board [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?

Mechanical Layer

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.

Fabricators will cut the 1W LED PCB in the right size from the available stock materials.

Besides, it can come in various shapes such as round-cornered, rectangular, or other custom shapes.

Also, you will rarely add detail tooling specifications or other mechanical data on the mechanical layer.

Routing Layer

This layer forms the area where the parts will interconnect and designers will spend more time making this layer perfect.

Routing layers are available on the outer and inner layers of the 1W LED PCBs.

Keep-out Layer

This is the layer that shows the working area of the PCB design.

For instance, the keep-out layer may draw back the parts to half an inch from the mechanical layer.

Keep out layer identifies the area on the PCB not meant for mechanical, or other purposes.

Power And Ground Planes

This layer enhances the performance of the 1W LED PCB and enables the distribution of ground and power across various components.

Also, they are available on the bottom, top, or internal components of the PCB.

When customizing 1W LED PCBs, ensure you provide the fabricators with all files that illustrate the planes in the design.

Silkscreen Layer Or Overlay

This layer offers text designators on the parts that are at the bottom and top part of the layer.

Also, you need to supply fabricators with additional files when manufacturing the bottom and top silkscreen layers.

Silkscreen layers are optional if you plan not to include texts on the PCB.

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.

Split Planes

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.

Solder Paste Layer

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.

Solder Mask Layer

This is a thin layer that offers protection to the top and bottom parts of the PCB.

Also, it prevents shorting of the traces when the PCB has debris.

What Quality Standards Should 1W LED PCB Comply With?
