5730 5V 10W White Led Module

5730 5V 10W 48mm White Led Module

Aluminum Pcb 20 Led Lamp Lighting Light

     The 5730 5V 10W white led module is a high power white light board made of 20 pieces of 5730 SMD LEDs arranged on a 48mm round aluminum PCB. It draws about three times the power of the 6 LED 3W boards of the same family and lights a wide area; it is suitable for jobs that need strong light such as worktop, workshop, camping and emergency lighting.

     The board works with DC 5V and draws about 10W at 5V (about 2A). Thanks to the current limiting resistors on the board it is powered from a fixed 5V source; a 5V adapter or power supply with at least 2.5A output that can easily supply this current should be used. The connection is made by soldering wires to the solder pads marked + and - on the front side.

     At 10W the board produces noticeable heat while working. The aluminum base is there to transfer this heat to a heat sink; the board must be fixed to a heat sink surface or a metal luminaire body with screws through its three mounting holes or with thermal adhesive. The 6mm hole in the middle can be used for a cable or screw passage.


Features:

• Product type: High power white light, round 5730 SMD LED module with 20 LEDs
• Operating voltage: DC 5V (constant voltage)
• Power: 10W
• Operating current: about 2A (at 5V)
• LED count and type: 20 pieces 5730 SMD LED (5.7mm x 3.0mm package)
• Light tone: white, 5000K colour temperature
• Beam angle: 120 degrees (5730 LED)
• Current limiting: 2 pieces 2Ω (code 2R0) SMD resistors on the board; no separate constant current LED driver is needed with a 5V supply
• Power supply: 5V adapter or power supply with at least 2.5A output; a computer USB port is not enough
• Connection: solder pads marked + and - on the front side
• Heat spreading: aluminum base; must be mounted on a heat sink surface or a metal body while working
• PCB structure: round aluminum PCB
• Material: aluminum PCB, white surface
• Mounting holes: 3 screw holes and 1 passage hole in the middle
• Outer diameter: 48mm
• Inner diameter: 6mm
• Weight: 4gr

Usage information:

• Solder the red (+) wire to the + pad of the board and the black (-) wire to the - pad; use wire of at least 0.5mm² (about 20AWG) for 2A. If the polarity is reversed the LEDs do not light and are stressed at their reverse voltage limit (5V); check the wiring before applying power.
• Fix the board to a heat sink or a metal luminaire body with screws through the three mounting holes or with thermal paste / thermal adhesive; do not run it for a long time without a heat sink.
• Since the board draws about 2A, use a logic level MOSFET that can carry at least 3A if you switch it on and off or dim it from a control circuit; do not drive the board directly from a control pin.

Application areas:

•  Kitchen worktop and work desk lamps
•  Workshop and electronics repair bench lighting
•  Camping lamps and portable lighting
•  Emergency lighting (with a 5V battery / power supply)
•  Spot, downlight and ceiling luminaire conversion
•  Repair of faulty LED bulbs and luminaires (light board replacement)
•  Showcase, shelf and storage lighting
•  Smart lighting projects with Arduino and ESP32
•  Education, STEM and DIY electronics projects
   

Points to consider:

•  The board is for DC 5V only. Do not connect a voltage higher than 5V (such as 9V or 12V); the current rises quickly and the LEDs and resistors will burn.
•  The board draws about 2A. A standard computer USB port (500-900mA) cannot supply this current; use a 5V adapter or power supply that gives at least 2.5A. A weak adapter heats up and its voltage drops.
•  When run without a heat sink the 10W board gets very hot in a short time; the LEDs darken and their life is shortened. Always mount it on a heat sink or a metal body and do not touch the board with bare hands while it is working.
•  Do not look directly at the lit LEDs from close up for a long time.

Package contents:
