4020 Side-Emitting RGB LED
4020 Side-Emitting RGB LEDs - Hongcheng Optoelectronics LED Manufacturer
Product Overview:
The 4020 side-emitting RGB LED uses a 4020 SMD package integrating red, green and blue chips. Side emission facilitates integration with light guide plates, light guide bars and edge-lighting structures. External driver circuitry adjusts the three colors' brightness to enable multicolor mixing, color switching, fades and flashing, for equipment status indication, button backlighting, electronic product decoration and ambient lighting.
Key Advantages:
- 4020 SMD package for compact circuit board layouts
- Side-emitting design for light-guide components and edge-lighting structures
- Integrated red, green and blue chips support multicolor mixing
- External drive enables dimming, color adjustment and fade effects
- A single device provides status indication in multiple colors
- Surface-mount design facilitates SMT production and assembly
Product Features:
Chips: Integrated red, green and blue LED chips produce different mixed colors by independently adjusting each color's brightness.
Emission: the side-emitting structure suits edge coupling into light-guide plates or strips. Actual lighting effects depend on light-guide design and mounting position.
Control: an external RGB driver circuit can use PWM dimming to produce color switching, fades, flashing and other effects.
Package: The 4020 SMD structure allows multicolor light sources in limited space. Confirm outline dimensions and pad layout against the corresponding datasheet.
Soldering: Suitable for surface-mount assembly. Check pin definitions and polarity during assembly, and follow datasheet requirements for reflow temperature and time.
Packaging: tape specifications, quantity per reel and supply format are confirmed for each model to match placement equipment and volume-production arrangements.

Q: What placement-machine accuracy does this LED require?
A: This product uses a 4020 package (4.0×2.0mm) with relatively large pads. Ordinary high-speed placement machines meet its needs, with no special equipment accuracy requirements. Its multiple-pad structure requires each stencil aperture to align with its corresponding pad. Supports lead-free reflow soldering (peak ≤260℃/≤3s).
