A decorative COB (Chip-on-Board) LED shaped like a snowflake, using the same technology found in Edison-style LED bulbs. Dozens of micro LED diodes are bonded onto a rigid metal backing and coated in silicone, producing a bright, warm, and uniform glow.
The ultra-thin PCB substrate allows light to softly shine through the back as well, creating a subtle diffused effect even though the LEDs are placed on one side only.
Key Features
- Warm Uniform Glow – Mimics a classic tungsten filament aesthetic
- 3 V Power – Simple parallel LED wiring, 100 mA maximum with current-limiting resistor
- PWM Dimmable – Adjustable brightness via pulse-width modulation
- Rigid Construction – Metal-backed PCB substrate
- Silicone Coated – Protected LED surface
How to Use
Connect 3 V to both ends of the filament. The cathode (negative) side is marked with a "−" symbol on the PCB. If it doesn't light up, reverse the connection. Use a current-limiting resistor to keep current at or below 100 mA.
Ideal For
- Miniature winter scenes and dioramas
- Dollhouses and model displays
- Decorative lighting projects
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
