LED light-emitting unit and light-emitting assembly

The utility model relates to an LED light-emitting unit and a light-emitting component, the top surface and the side surfaces of a carrier body of the LED light-emitting unit can transmit light, and light emitted by a micro LED chip arranged in an accommodating cavity can be emitted through the top surface and each side surface of the carrier body, so that the LED light-emitting unit can emit light from multiple directions and multiple surfaces. Therefore, the light-emitting angle and the light-emitting effect can be greatly improved. When the LED light-emitting unit is arranged on the external circuit board to manufacture the light-emitting assembly, the light-emitting normal direction of the main light-emitting face of the LED light-emitting unit is perpendicular to the normal direction of the circuit board, the LED light-emitting unit can emit light from multiple directions and multiple faces, and the light emitted by the LED light-emitting unit is emitted out from the light-emitting face of the light-emit
