5730 5V 3W Yellow Led Module

5730 5V 3W 31mm Yellow Led Module

Aluminum Pcb 6 Led Lamp Lighting Light

     The 5730 5V 3W yellow led module is a small lighting board made of 6 pieces of 5730 SMD LEDs arranged on a 31mm ring shaped aluminum PCB, giving a yellowish warm white light. Thanks to its warm light colour it is preferred in jobs that need warm toned light suitable for the home, such as bedside lamps, night lights, cabinet interiors and showcase lighting.

     The board works with DC 5V and draws about 3W at 5V (about 600mA). Since there are current limiting resistors on the board, it can be powered from fixed 5V sources such as a USB output, a 5V adapter or a powerbank. The connection is made by soldering wires to the solder pads marked + and - on the front side.

     The aluminum base spreads the heat of the LEDs; the board can be fixed to a heat sink surface or a metal luminaire body with screws through its two mounting holes or with thermal adhesive. The 10mm hole in the middle can be used for a cable or screw passage. The same family also has a white light 3W version and a 20 LED 10W version.


Features:

• Product type: Yellow (warm white) light, round 5730 SMD LED module with 6 LEDs
• Operating voltage: DC 5V (constant voltage)
• Power: 3W
• Operating current: about 600mA (at 5V)
• LED count and type: 6 pieces 5730 SMD LED (5.7mm x 3.0mm package)
• Light tone: yellowish warm white
• Beam angle: 120 degrees (5730 LED)
• Current limiting: 3 pieces 10Ω (code 100) SMD resistors on the board; no separate constant current LED driver is needed with a 5V supply
• Power supply: USB 5V output, 5V adapter or powerbank (at least 1A recommended)
• Connection: solder pads marked + and - on the front side
• Heat spreading: aluminum base, can be mounted on a heat sink surface or a metal body
• PCB structure: ring shaped aluminum PCB
• Material: aluminum PCB, white surface
• Mounting holes: 2 screw holes (4mm) and 1 passage hole (10mm) in the middle
• Outer diameter: 31mm
• Inner diameter: 10mm
• Weight: 3gr

Usage information:

• Solder the red (+) wire to the + pad of the board and the black (-) wire to the - pad; 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 surface or a metal luminaire body with screws through the two mounting holes or with thermal paste / thermal adhesive.
• Since the board draws about 600mA, if you switch it on and off or dim it from a control circuit, drive the board through a logic level MOSFET or transistor, not directly from a control pin.

Application areas:

•  Making bedside and desk lamps
•  Night lights and warm decorative lighting
•  Cabinet, drawer and shelf interior lighting
•  Showcase and product display lighting
•  Scale models, dioramas and hobby projects
•  Repair of faulty LED bulbs and spot luminaires (light board replacement)
•  Camping lamps powered by USB and powerbank
•  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 600mA. A computer USB 2.0 port (500mA) may not be enough; use a 5V adapter or powerbank that supplies at least 1A.
•  For long operation mount the board on a heat sink surface or a metal body; a board run in the air without heat spreading gets hot and the LED life is shortened.
•  Do not look directly at the lit LEDs from close up for a long time.

Package contents:
