LED POLARITY
January 04, 2022
LED arrays, components and wiring are color-coded, usually red (+), and black (-). Unlike traditional incandescent/halogen lamps, an LED array will function only when voltage is applied in the forward direction of the diode. If voltage is reversed, no current flows thus no light emitted. If the reverse voltage exceeds the LED chip ‘breakdown’ voltage, the LED array will be damaged.
Installers should always pay attention to the wiring, connectors, and color-coded polarity.
