Applications

• Red light and near-infrared phototherapy equipment, including medical devices, facial beauty panels, deep-tissue heating pads, joint relief and muscle recovery equipment (photobiomodulation / PBM).
• Horticultural grow lights for the Emerson effect, plant photoperiodism, shade avoidance response and flowering phases.
• Optical sensing and machine vision, including specialized camera illuminators, barcode readers, spectral inspection and night vision enhancement setups.
• R&D and laboratory prototypes, biomedical research setups and custom DIY optical equipment.

Operating and Safety Guidelines

• Current-limiting circuit required: With a forward voltage of 1.8V–2.0V DC, the LED must be driven by a dedicated constant current driver (600mA–700mA) or an appropriate current-limiting circuit. Direct connection to a constant voltage supply (e.g., 5V, 12V) without current control can cause thermal runaway and burn out the LED.
• External aluminum heatsink required: 3W LEDs generate localized heat during continuous operation. Mount the LED directly onto an adequate external aluminum heatsink using thermally conductive adhesive or thermal grease before applying power to prevent permanent chip failure.
• Invisible radiation / eye safety: At 730nm–740nm, the light appears very faint to the human eye, but high-intensity near-infrared energy is emitted. Do not stare directly into the LED beam when powered on. Wear appropriate infrared eye protection during testing or operation.
