Knowledge Area provided by GMKJ LEDs
Using 2020 SMD LEDs (smaller package) instead of 3535 SMD LEDs (larger package) makes sense in certain special applications because of these technical and practical reasons:
🔹 1. Optical Design & Beam Control
Smaller LED packages (2020) allow tighter spacing and higher packing density on a PCB.
This creates smoother light mixing (no visible hot spots) - especially important in backlighting, displays, signage, or small light guides.
With 3535, the emission area is larger, which can cause non-uniform illumination in compact optical systems.
🔹 2. Size & Space Constraints
In compact devices (wearables, medical instruments, fine-pitch LED displays), space is very limited.
2020 LEDs fit into miniaturized designs where 3535 packages simply cannot be used.
Above picture is for 2020 smd led application for the photography lights.
It needs small size with high power. So 2020 smd leds should be better compared with 3535 smd leds.
🔹 3. Thermal & Power Distribution
3535 LEDs usually run at higher power per chip → more heat per point.
2020 LEDs, being lower power per unit, spread heat more evenly when many are used.
This is better for applications where heat management is critical and no heavy heat sink is possible.
🔹 4. Electrical Characteristics
2020 LEDs typically have lower forward current rating and can be driven in large arrays with precise control.
For display or horticulture light panels, using many small LEDs helps achieve fine current distribution and adjustable spectral control.
🔹 5. Cost & Flexibility
Sometimes, multiple 2020 LEDs can be cheaper and more flexible in design than fewer 3535 LEDs.
Designers can combine different colors/spectra in close proximity (e.g., RGB or full spectrum) using small packages.
✅ In short:
Use 2020 SMD LEDs when you need compact size, fine optical control, better uniformity, or multi-color mixing.
Use 3535 SMD LEDs when you need higher power per LED, stronger radiant flux, or easier thermal handling with fewer components.
