21W LED PCB board use 9V High Volt LED Chip parallel directly in order to avoid one being defective and the whole light will not turn on

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 parallel to share a common current-limiting resistor like in the figure. More than all three LEDs (with common resistor) are connected in parallel to Power supply.

LEDs in parallel using High Volt 2835 SMD Chip. There is a possibility of varying in the forward current that is generated from the LEDs to. The variance could be decreased by using LEDs from the same manufacturing lot, but manufacturers don't rely on this and use "binning" to classify LEDs into matched lots for sensitive applications.

It is a High Volt 2835 SMD chip 1W 130-140lm offers the option of 3V 6V 9V 36V.High bright compact design, and a standard smd package 2835 0.2W 0.5W 1W that comes with several Volt options of 3V6V9V 18V 36V for an array of diverse lighting requirements. A high-quality compact design, extensively used in numerous lighting applications.

Notes:
1. The led lighting board can directly function on DC 12V. Please contact us if you require a 24V, 32V, 36V or 48V LED light, using the High Volt 2835 SMD Chip. It can be used to parallel LEDs directly.
2. LED PCB board lights source Aluminum plate base board has to be paired with a heatsink as well as a cooling fan. The majority of the aluminum and housing bodies made of coper are good heatsink.
3. Check that the wire's and LED welding temperatures are lower than 85 It is recommended to keep the temperature below 85degC Celsius
