ASMTLED Super Bright 12V Integration COB LED Chip Instruction Manual

1. Introduction

Thank you for choosing the ASMTLED Super Bright 12V Integration COB LED Chip. This high-power integrated chip is designed for various DIY lighting applications, including floodlights, spotlights, landscape lighting, and more. Available in 10W, 20W, 30W, and 50W variants, these chips provide efficient and powerful illumination when properly installed with a compatible LED driver and heat sink.

2. Safety Information

• Always disconnect power before installation or maintenance.
• This product is an electrical component. Installation should be performed by qualified personnel if you are unsure.
• Ensure proper heat dissipation. Operating the LED chip without an adequate heat sink will lead to overheating and premature failure.
• Use only a compatible DC 12-15V LED driver (not included) that matches the wattage requirements of the chip.
• Do not look directly into the illuminated LED chip for extended periods, as it can cause eye strain or damage.
• Keep out of reach of children.

3. Product Overview

The ASMTLED COB LED Chip is a high-power, integrated light source. It features a compact design with a central light-emitting area and mounting points for secure attachment to a heat sink. Each chip has clearly marked positive (+) and negative (-) terminals for electrical connection.

4. Setup and Installation

This COB LED chip requires careful installation due to its high power output and the need for external components.

4.1 Required Components (Not Included)

• LED Driver: A constant current LED driver with a DC 12-15V output, matching the wattage of your COB chip (e.g., a 30W driver for a 30W chip).
• Heat Sink: An appropriately sized aluminum heat sink to dissipate heat generated by the LED chip. Thermal paste or thermal adhesive is also recommended.
• Mounting Hardware: Screws or other fasteners to secure the LED chip to the heat sink.

4.2 Installation Steps

1. Prepare the Heat Sink: Ensure the surface of the heat sink where the LED will be mounted is clean and flat. Apply a thin, even layer of thermal paste or thermal adhesive to the back of the LED chip or the mounting area on the heat sink.
2. Mount the LED Chip: Carefully place the LED chip onto the heat sink, aligning the mounting holes. Secure the chip using appropriate screws, ensuring firm contact for optimal heat transfer. Do not overtighten.
3. Wire the LED Chip: Identify the positive (+) and negative (-) terminals on the LED chip. Connect the positive output from your LED driver to the positive terminal of the LED chip, and the negative output from the driver to the negative terminal of the LED chip. Ensure all connections are secure and insulated.

5. Operating Instructions

Once properly installed and connected to a compatible LED driver, the ASMTLED COB LED chip will illuminate when power is supplied to the driver. There are no user-adjustable controls on the chip itself.

6. Maintenance

• Keep the LED chip and heat sink clean from dust and debris to ensure optimal performance and heat dissipation.
• Periodically check electrical connections for tightness and signs of wear.
• Ensure the heat sink has adequate airflow and is not obstructed.

7. Troubleshooting

• No Light: Check the power supply to the LED driver, ensure the LED driver is functioning, and verify all wiring connections (positive to positive, negative to negative) are correct and secure.
• Dim Light: Ensure the LED driver is providing the correct voltage and current for the specific wattage of your LED chip. Check for any loose connections.
• Overheating/Premature Failure: This is almost always due to insufficient heat dissipation. Ensure the LED chip is firmly mounted to an adequately sized heat sink with thermal paste/adhesive. Verify the heat sink is not obstructed and has proper airflow.
