18W LED PCB board use 9V High Volt LED Chip to parallel LEDs directly in order to avoid one being defective.

LED light PCB board, 12V constant voltage PWM dimmable LED light for DC dimmer. 12V LED light that uses 9 V High Volt 2835 SMD chip to connect parallel LEDs directly, Avoid one light that is not working and the whole light will not turn on.

3 LEDs are wired in series to share a resistor that limits current as shown in the figure. All LEDs (with the same resistor) are connected in parallel to the Power supply.

LEDs running in parallel using High Volt 2835 SMD Chip, There is a possibility of varying in the forward current of an LED. The variation might be reduced by using LEDs from the same manufacturing lot, but companies don't depend on this. They use "binning" to sort LEDs into matching lots for sensitive applications.

A High Volt 2835 SMD Chip 1W 130-140lm offers choice of 3V6V9V18V 36V.High high brightness, compact design and a standard smd package 2835 0.2W 0.5W 1W that comes with several volt choices 3V 6V 9V 18V 36V to satisfy the wide variety of lighting application requirements. Compact and high-quality design that is extensively used in a variety of lighting applications.

Notes:
1. The led lighting board is able to directly operate on DC 12V. Please contact us If you require 24V 28V 32V 36V 48V LED light with the High Volt 2835 SMD Chip to direct LEDs in parallel.
2. LED PCB board lighting source Aluminum plate base board must be fitted with a heater or cooling fan. The majority of the aluminum and coper housing bodies make a good heatsink.
3. Make sure that the wire and LED welding temperature is at or below 85 (or less)degC Celsius
