LED Application Scenarios: Bi Color 3030 SMD LED in Red & Blue

Two-tone lighting has become a signature of modern product design, from warning indicators that must switch between red and blue to decorative fixtures that blend warm and cool accents. A bi-color LED lets a single component deliver two distinct colors, which simplifies the layout, cuts component count and improves reliability compared with pairing two separate lamps.

This article highlights one specific model from Dongguan Lanjin Optoelectronics Co., Ltd. — the Bi Color 3030 SMD LED (Red & Blue). As a practical LED SMD bicolor built on a compact 3.0 × 3.0 × 0.62mm package, it pairs a red channel at 620–630nm with a blue channel sitting precisely in the smd led wavelength 460-473nm range, giving designers crisp, high-contrast dual-color effects from a single 1W-class emitter.

Highlight Model: Bi Color 3030 SMD LED Red & Blue

• Package: 3030 SMD, 3.0 × 3.0 × 0.62mm surface-mount footprint
• Emitting color: red & blue in a single device
• Wavelength: red 620–630nm / blue 460–473nm
• Power & drive: 1W, 150mA forward current, 1.8–2.4V / 2.8–3.4V forward voltage
• Optics: 120° viewing angle for wide, even coverage
• Reliability: 60,000-hour lifespan, 2-year warranty, low thermal load
• Compliance & packing: RoHS & Reach certified, 5,000pcs per reel

Technical Parameters

Electrical and optical data are measured under standard conditions. The 120° beam and 1W-class output make this bi-color 3030 a natural fit for fixtures that must switch or blend red and blue light without adding a second emitter.

Application Scenarios

1. Status, warning & indicator lights: the red/blue dual output is ideal for equipment that signals different states — for example red for fault, blue for standby — using one compact device.
2. Automotive & traffic electronics: cabin accent lighting, dashboard indicators and auxiliary signaling benefit from the robust 3030 package and 60,000-hour life.
3. Signage & two-tone displays: the 460–473nm blue balances the 620–630nm red for high-contrast lettering, logos and backlit panels.
4. Smart lighting & decoration: designers blend the two channels to create vivid color-rich ambience in lamps, toys and home electronics.
5. SMD LED PCBA light bars: the same chips are assembled onto the company’s PCB boards, including an aluminum 4014 SMD LED PCBA rigid bar that can carry up to 144 LEDs — the practical 144 LED PCBA bar format used in linear lighting, strip and backlight designs.

Why the 460–473nm Blue Channel Matters

The 460–473nm band is a deep, saturated blue that reads clearly against red and remains stable across temperature and drive current. Pairing it with a red channel in one package keeps the two colors perfectly registered, so mixed effects stay clean and the emitted smd led wavelength 460-473nm output supports everything from crisp two-tone signage to soft decorative glows.
