DIY USB Mini Led Lamp Using JLPCB SMT Assembly Services.

In this article, We are going to make a Mini USB Led Lamp. this is kind of a night lamp. and this led lamp is very small in size and very useful.

I have made this Mini USB Led Lamp using the JLCPCB SMT assembly Services.

I have also designed the case and diffuser for this led lamp, By using diffuser we got even diffused warm light.

We can use this USB Led lamp for various purpose.

Like We can use as...

•  Night bulb.
• Warm light for rooms.
• Emergency lights for trips.

This led lamp produces dim warm light which is eye soothing.

Size of this USB Led lamp is so small , that we can easily carry inside our pocket.

This lamp has USB-A Connector. And through this USB connector we can connect to any travel adapter, most of adaptor comes with USB-A interface.

Just connect this USB Led lamp to adapter and plugin the adapter to electrical board.

And your night bulb is ready.

So to power-up this lamp we only required an adapter and nowadays everyone has these adapters in their houses.

And apart from this adapter we can also give power Supply from the power banks.

Power banks also has USB-A interface.

And we all know laptops are also comes with USB-A interface. So we can connect this lamp to Laptop as well. and enjoy the dim warm light from this lamp.

This USB Lamp has 2 LED which consume few milliwatts of power. So by using this led lamp we can save electricity as well.

I have used PLA filament, i.e. Polylactic acid, To make the case and diffuser and we all know PLA is biodegradable , So in this way, this USB Led lamp is also environmental friendly. 

This is the Schematic of PCBs. If you want Your own custom designed PCBs, Then you can download this schematic.

After making the Schematic, Convert it into PCB, Arrange and place all the components in desirable places, Once the layout is ready route the wiring and complete the design of PCB.

After The completion of PCB design, You need to download three files which will required during PCB order. These files are BOM, Gerber and CPL that is pick and place file.

This project is sponsored by JLCPCB. JLCPCB is a full feature Printed Circuit Board manufacturing service.

Turn your DIY breadboard circuits into professional PCBs– get 10 boards for approximately $5 + shipping (which will vary depending on your country).

Once you have your Gerber files, you can order the PCB. Follow the next steps.

1. Download the Gerber files –click here to download the.zip file.

2. Go to JLCPCB website and Click on Quote Now button under PCB assembly.

3.Upload the Gerber file you downloaded in the last step. Upload the.zip file or you can also drag and drop the Gerber files.

After uploading the zip file, you’ll see a success message at the bottom if the file is successfully uploaded. You can review the PCB in the Gerber viewer to make sure everything is good.

JLCPCB can grab all the PCB details and automatically fills them for you.

Select the PCB quantity and color masking of PCB by your self. I am selecting white color.

Scroll down below and select for PCB assembly.

Scroll down below and select for PCB assembly.

Here you have to select on which Side you want to PCB assembly top side or bottom side or on both side. In my case I want only on top sides. After that click on confirm button.

For PCB assembly we need two more files, One is BOM that is bill of material and the second one is CPL that is pick and place file, Upload these two files one by one.

After that click on next button.

All the components were shown here that are to be assembled.

In case if you want to not assemble any particular component then you can de-select that components.

After checking all the components click on next button.

Here you will see a computer version of components placement which seems not accurate. This is only for reference purpose.

Now click on save to cart to complete your order.

After seven days, PCBs arrived at my place. As usual the quality of PCB is very premium, and the Components are soldered very well.

Traces are perfect, silkscreen is fine, White color PCB masking looks very beautiful and PCBs look pretty professional.

This is the 3d Model of case and diffuser.

Download these files and print your own case and diffuser.

Click here to download the CAD file.

Here our case and diffuser is ready, let's quickly attached the PCB to this case and diffuser.

Our USB Mini lamp looks beautiful with the case.

Power up the lamp using adapter or power bank and enjoy the dim warm light with your favourite person.

That's it for this article. 

Thank you so much for reading.

Stay healthy stay safe and keep Learning, bye bye.
