The L2S15 is a portable LED headlight system designed for medical use, particularly for illuminating wounds or surgical sites. It utilizes a lithium-ion battery and an LED light source, offering co-axial and shadow-free illumination with consistent brightness and excellent color rendering. As a portable device, it eliminates the need for supplementary holders or fiber optic cables.
Function Description:
The L2S15 operates by delivering DC voltage from its battery to an LED device via a step-down circuit, generating light through a lens. This design ensures consistent brightness even as the battery voltage decreases. The system includes a main control unit, a battery pack, an LED lens module, and a remote controller for ease of use. It is designed with a latching power switch circuit and protection circuits for overcurrent and overvoltage, ensuring safe charging and operation.

Usage Features:
Preparation before usage:
- Component Check: Verify all components are present as listed in the manual.
- Battery Charging & Assembly: Fully charge the battery pack before first use. Connect the power supply to the charger. A green light on the charger LED indicates a full charge. Assemble the control unit with the charged battery, then connect the LED lens module wire to the circular connector of the control unit.
Operating Instructions:
- Placement: Secure the main body to a waist belt or inside a pocket.
- Headband/Glasses Attachment: When using a headband, connect the LED lens module to the headband attachment and adjust it to your head. For surgical telescopes, connect the LED lens module to the glasses nose bridge.
- Wire Management: Use gown clips to fix the wire and remove the protection cap from the LED lens module.
- Power On & Adjustment: Turn on the control unit to activate the light. Adjust the LED lens module's position as needed. The external LED lens module's temperature can reach up to 54℃ during use, so caution is advised.
- Intensity Change: Press the intensity change button on either the control unit or the remote controller to adjust the light intensity (1st to 4th step).
- Battery Status: The control unit displays the remaining battery percentage (0-99%) or "FU" for fully charged. A "Beep" alarm sounds when the remaining charge is below 10%, indicating the need for recharging. The device will shut down 10 minutes after the "Beep" sound.
- Battery Pack Release: To release the battery pack, align the two charging terminals of the control unit and battery pack. Press the battery release button with one hand while holding the sides of the battery pack with the other, then pull the battery pack downward to disassemble.
Remote Controller (RC15):
- Power On/Off Button: Turns the LED lens on/off.
- Intensity Change Button: Changes LED intensity from 1 to 4.
- Battery Entrance: Requires two 1.5V AAA batteries.
- Pairing: The control unit and remote controller are pre-paired. Instructions are provided for setting up or releasing pairing if needed. To pair, turn on the control unit, push the pairing switch for one second (blue light blinks), then push and release the On/Off button of the remote controller (blue light lingers and turns off). To release pairing, turn on the control unit, push and hold the pairing switch for more than 5 seconds (blue light blinks), then push and release the On/Off button of the remote controller (blue light lingers and turns off).
