Behind every fogged glass door, inside every beverage cooler and walk-in cold room, a light source does one of the hardest jobs in lighting: staying bright at −25°C, shrugging off condensation, and refusing to fail where nobody wants to send a technician. That job usually belongs to a small side-emitting LED — and the 3014 Side View White SMD LED has become the workhorse of the cold chain.
A refrigerated display case is a hostile home for any light source. The lamp sits inches from a cold glass door and cycles between cabinet temperature and sales-floor temperature dozens of times a day. Moisture creeps in through gaskets, optics fog over, and drivers are squeezed into spaces with almost no airflow. The result is a familiar failure pattern: generic LEDs that look fine on a datasheet but drift in colour, dim, or die within the first year — right where replacement is most expensive.
What buyers actually need: a stable white point across the whole cabinet, a package narrow enough to hide inside a door frame, low power per unit so dozens can run from one driver, and a temperature rating that starts at −40°C rather than +25°C.
BOSMFC’s 3014 Side View SMD LED measures just 3.0 × 1.4 × 1.37 mm and emits from its side face, so the light travels parallel to the PCB. That single design detail solves the cold case problem: the chip can be mounted at the edge of a light guide or a door frame, and the beam is injected sideways into the cabinet instead of blinding the shopper. Running at 20 mA and 2.8–3.6 V, it produces 8–12 lm across a 2800–12000 K range, backed by a 50,000-hour lifetime and a 3-year warranty.
| Parameter | Specification | Why It Matters in a Cold Case |
|---|---|---|
| Package | 3.0 × 1.4 × 1.37 mm side view (3014) | Fits inside slim door frames and edge-lit light guides |
| CCT range | 2800–12000 K white | One platform covers warm deli cases and cool beverage coolers |
| Drive | 20 mA, VF 2.8–3.6 V, 60 mW | Dozens of chips per door run from one low-cost driver |
| Output | 8–12 lm, 120° viewing angle | Even shelf illumination without hot spots on packaging |
| Temperature | −40 to +85 °C operating | Rated for freezer cycling, not just room-temperature benches |
| Reliability | 50,000 h, San’an chip, 3-year warranty | Fewer service calls where access is hardest |
| Check | What to Ask |
|---|---|
| Colour consistency | Ask for binning data — a mixed reel shows as visible patches across a glass door. |
| Condensation path | Confirm the LED sits behind a sealed lens or is potted, not exposed to drip lines. |
| Thermal derating | Verify current at the highest cabinet temperature, not at 25 °C on a bench. |
Dongguan Lanjin Optoelectronics Co., Ltd. (东莞市蓝晋光电有限公司), trading under the BOSMFC brand, has manufactured LEDs since 2005 from a 2,500 m² anti-static, constant-temperature workshop in Dongguan, China. The company holds ISO9001:2015 certification, two national invention patents and twelve utility patents, and ships roughly 500KK pieces per month with a 5–15 day lead time on standard reels — including this 3014 side view white series at 3000 pcs per reel.
The same side-view platform covers the rest of the cabinet: the ultra-thin 020 and 215 side view LEDs for tight light guides and TV-style backlights, the 335 series for decorative edge lighting, and 2835 / 5730 white chips when higher flux is needed. Buyers who want the whole door assembly rather than loose components can also use Lanjin’s aluminium PCB and SMD LED PCBA service, including sensor-ready boards. Samples are available for evaluation, and OEM/ODM colour sorting is offered on request.
LED lights the world, Lanjin lights your life. If you are sourcing lighting for freezers, coolers or cold rooms, send your cabinet drawing and target CCT — the engineering team will match the right side-view bin for your door.
