2835 Dome Narrow Beam SMD LED 15° 30° Red 620nm IR730 850 940nm For Automotive

This narrow-beam dome-lens 2835 SMD LED is a compact surface-mount optoelectronic component with overall physical dimension of 3.5(L)×2.8(W)×2.45(H) mm, adopting precision hemispherical convex silicone dome encapsulation for focused beam shaping. The product supports customizable narrow viewing angles including 15° and 30°, and multiple optional emitting spectrums covering visible red light (620~630nm) and infrared wavelengths at 730nm, 850nm, 940nm to satisfy diversified application requirements across automotive lighting, traffic warning equipment, medical beauty apparatus and industrial infrared inspection instruments.

The LED is built with high thermal conductivity modified PPA lead frame, which effectively accelerates internal heat conduction during continuous energized operation, restraining excessive junction temperature rise and long-term lumen depreciation. Designed with standard dual-terminal pad layout marked IR+ (Anode) and IR- (Cathode), the component is fully compatible with high-speed automatic SMT pick-and-place equipment and lead-free reflow soldering processes, suitable for large-scale automated PCB assembly. All production batches comply with international RoHS and REACH environmental control regulations, restricting hazardous substances to meet global electronic and lighting product import standards.

Two lens surface options are available for flexible optical matching: clear transparent dome for high-concentration spotlight output and frosted diffused dome for mild uniform illumination, allowing customers to select appropriate versions according to their finished luminaire optical design scheme. The rated standard operating forward current is 20mA per chip, with stable electrical parameters and consistent chromaticity performance during mass production.

Forward Voltage tolerance: ±0.1V; Dominant wavelength tolerance: ±5nm; Luminous intensity tolerance: ±15% within production batches.

Only single-time reflow soldering is permitted; repeated high-temperature oven passing will damage internal chip and silicone lens structure.

• Lead-free soldering: peak temperature ≤260℃, heating rate ≤4℃/s, soaking duration over 120s within 180~200℃;
• Leaded soldering: peak temperature ≤230℃, heating rate ≤4℃/s, soaking duration over 120s within 140~160℃.

• Unopened original moisture-proof reel packaging should be stored at ambient temperature 0~30℃ with relative humidity below 60%, valid storage period up to 60 days;
• After unpacking the tape reel, all LEDs shall be fully used within 24 hours; leftover unused components must be baked at 60℃ for 12~24 hours before subsequent SMT processing to eliminate internal moisture.

All products pass standard reliability tests including high-low temperature cycling (-40℃~+85℃ for 100 cycles), high temperature & high humidity aging (85℃, RH85% for 1000H), long-time powered aging at rated current, with final lumen decay controlled below 30% after full testing.
