1. Introduction
This manual provides instructions for the LCFOCUS LC-L67 SERIES LED Lens Kit. This kit is designed to focus light from high-power LED chips, offering various beam angles for different lighting applications. It includes an optical glass lens, a reflector, and a fixed bracket for secure mounting.
2. Safety Information
- Do Not Disassemble: Unauthorized disassembly of the lens components beyond the intended assembly process may damage the product or affect its optical performance.
- Handle with Care: The optical glass lens is fragile. Avoid dropping or subjecting it to impact.
- Keep Away from Water: Avoid use in damp environments to prevent damage to the lens or associated electrical components (if used with an LED chip).
- Temperature: Ensure the operating temperature is within the specified range (-30 to 200 degrees Celsius) to prevent damage to the lens material.
3. Product Overview
The LCFOCUS LC-L67 SERIES LED Lens Kit consists of an optical glass lens, a reflector, and a fixed bracket. These components work together to collimate and focus light from a high-power LED chip.
4. Setup and Assembly
Follow these steps to assemble your LCFOCUS LED Lens Kit:
- Carefully unpackage all components: the optical glass lens, reflector, fixed ring, and fixed holder.
- Remove any protective films from the reflector and lens surfaces.
- Place the reflector into the fixed holder, ensuring it sits flush.
- Position the optical glass lens on top of the reflector within the fixed holder.
- Secure the lens and reflector by screwing the fixed ring into the fixed holder. Ensure a snug fit without overtightening.
- Mount the assembled lens kit over your high-power LED chip, aligning the lens with the LED emitter. The fixed holder has four 4.5mm holes for mounting.

5. Operating Instructions
The LCFOCUS LED Lens Kit is a passive optical component designed to work in conjunction with a high-power LED chip. Its operation is primarily determined by the chosen lens angle and proper alignment.
- Beam Angle Selection: Choose the appropriate lens (30, 45, 60, 90, or 120 degrees) based on your desired light distribution. A lower degree provides a more focused beam, while a higher degree offers a wider spread.
- Alignment: Ensure the lens is perfectly centered over the LED emitter for optimal light output and beam uniformity.
- Powering the LED: Once the lens kit is securely installed, power on your LED chip according to its manufacturer's instructions. The lens will then direct the light as designed.
6. Maintenance
- Cleaning: Gently clean the glass lens surface with a soft, lint-free cloth and a suitable optical cleaning solution. Avoid abrasive materials that could scratch the glass.
- Inspection: Periodically check for any dust accumulation on the lens or reflector, which can reduce light output. Ensure all components remain securely fastened.
- Storage: When not in use, store the lens kit in a clean, dry environment to prevent dust and damage.
7. Troubleshooting
- Uneven Light Distribution:
- Check if the lens is properly centered over the LED chip.
- Ensure the reflector and fixed ring are correctly seated and secured.
- Reduced Light Output:
- Inspect the lens and reflector for dust, dirt, or smudges and clean as per maintenance instructions.
- Verify that the LED chip itself is functioning correctly.
- Loose Components:
- Tighten the fixed ring gently to secure the lens and reflector.
- Ensure the entire assembly is firmly mounted to the fixture.
