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 (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- 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.
