Unternehmensnachrichten über LED Application Scenarios: High Voltage 36V 1W 2835 SMD LED for Driverless Bulbs, Tubes & Linear Modules

In a low-cost LED bulb, the driver is often 30–40% of the bill of materials — and the single most common reason the bulb comes back. Electrolytic capacitors dry out, ICs fail on surge, and the whole assembly grows taller than the shade allows. The alternative that Chinese fixture engineers have quietly adopted is simpler: move the voltage into the chip itself.

The Model: High Voltage 36V 1W 2835 SMD LED

The 36V 1W 2835 SMD LED from the BOSMFC range is a high-voltage emitter that runs directly from a 36 V rail, with a 2.8 × 3.5 × 0.8 mm footprint, CRI 85 and a colour temperature span from 2700 K warm white to 12,000 K cool white. Instead of stringing eleven or twelve low-voltage chips in series to reach mains-derived voltage, one chip handles the drop — fewer solder joints, a shorter board, and a much thinner finished lamp.

Why a 36 V Chip Changes the Bill of Materials

Five Application Scenarios That Fit This Emitter

1. Driverless LED Bulbs (A60, A70, Candle, Golf Ball)

A 36 V platform lets a bulb reach a 220 V rail with a compact linear IC instead of a transformer driver. The result is a lighter lamp, a shorter neck and one less component family to qualify.

2. Linear Tubes and Battens

Long aluminium boards love high-voltage strings: fewer chips per metre means wider spacing, easier thermal spreading and a lower component count on the SMT line.

3. Downlight and Spotlight Engines

Small apertures cannot host a bulky driver. A high-voltage chip plus a linear IC fits inside a GU10 or a shallow recessed can, and CRI 85 keeps retail and hospitality colour rendering acceptable.

4. Mirror Lights, Cabinet Lights and Appliances

Wherever a 36 V DC rail already exists — range hoods, bathroom mirrors, display cabinets — the chip can be driven with a simple constant-current stage and no mains isolation.

5. Backlight and Indicator Modules

The 120° beam and stable 2700–12,000 K range make it usable in signage backlighting and panel indicators where a 36 V bus is already routed.

Four Design Notes Before You Commit a Board

• Mind the Vf window: 34–38 V binning gives the linear IC its headroom; calculate dissipation at the top of the window, not the typical value.
• Cool the IC, not just the LEDs: the aluminium core should carry both the emitters and the linear device.
• Keep the string below the bus: total Vf at minimum line voltage must stay under the rectified rail, or flicker appears at 10% dimming.
• Match CCT across bins: mixing 2700 K and 6500 K parts in one lamp is the fastest route to a warranty argument.

Sourcing the Chip

The emitter is produced by Dongguan Lanjin Optoelectronics Co., Ltd. (东莞市蓝晋光电有限公司), the manufacturer behind BOSMFC. Founded in 2005, the company runs a 2,500 m² facility with constant-temperature anti-static workshops, holds ISO9001:2015 certification and two national invention patents, and supplies SMD LED, through-hole LED, LED displays and LED PCB assemblies. All products meet EU RoHS, reels ship with anti-static bag and carton, and the factory quotes 500KK pcs monthly capacity with 5–15 day delivery.

Send your bulb or tube design and target lumen output to the Lanjin team — they will confirm the 36 V bin, CCT and reel quantity before you lock the PCB layout.
