bedrijfsnieuws over LED Application Scenarios: 2W 3535 SMD LED Dome Lens Bi-Color Red & White for Headlamps & Work Lights

Portable lighting designers keep asking the same question: how do you fit a bright white work beam and a red night-vision beam into one 3.5×3.5mm footprint? The answer is the 2W 3535 SMD LED dome lens bi-color red & white from BOSMFC — a two-die package driven at 350mA that delivers 100–140lm of white light or 70–90lm of 620–630nm red, selected by simply reversing the polarity of the drive channel.

One Footprint, Two Lighting Modes

Traditional dual-mode lamps need two separate emitters, two optical paths and twice the board space. A bi-color 3535 with an integrated dome lens collapses that into a single reflow step:

• White mode (6500–10000K) — 100–140lm for inspection, work and general illumination.
• Red mode (620–630nm) — 70–90lm at a low 1.8–2.4V, preserving natural night vision and cutting glare.
• 30° dome lens — moulded silicone optic throws a tight, uniform spot without a secondary lens holder.
• 350mA, 2W — a single constant-current channel does the job; no dual driver architecture required.
• 99.99% gold wire bonding — superior ESD protection and stable lumen maintenance over 50,000 hours.

A Full Bi-Color Family on the Same Platform

Red and white is only the most popular pairing. The same 3535 dome-lens body is binned in four combinations, so a product family can share one PCB, one optic and one gasket set.

Where Dual-Color 3535 LEDs Earn Their Place

Electrical & Mechanical Quick Reference

Design tip: keep the thermal pad soldered to at least 100mm² of copper and drive both dies with a two-channel constant-current IC so the white and red modes can be switched without a mechanical shutter.

Quality and Supply Behind the Part

The 3535 bi-color dome lens is manufactured by Dongguan Lanjin Optoelectronics Co., Ltd. (东莞市蓝晋光电有限公司), an LED factory established in 2005 with a 2,500m² constant-temperature, anti-static workshop in Dongguan, China. The company is ISO9001:2015 certified, holds 2 national invention patents and 12 utility-model patents, and ships every part RoHS and Reach compliant. Monthly capacity reaches 500KK units, with MOQ from 2,000pcs, 5–15 day lead times and a 3-year warranty; the same lines also run 3030, 2835 and 5050 dome-lens platforms plus full through-hole, SMD and LED PCB assembly services for buyers consolidating their lighting BOM.
