| Zusammenfassung: | An LED light-emitting unit comprising: a base (1) provided with an accommodating cavity (11) and, arranged within the accommodating cavity (11), a red light LED chip (2), a blue light LED chip (3), and a green light LED chip (4). The accommodating cavity (11) is provided with a side opening (12). The red light LED chip (2), the blue light LED chip (3), and the green light LED chip (4) are arranged in a preset arrangement at different heights in the direction from the opening (12) of the accommodating cavity (11) to a bottom part (13). With the three LED chips being arranged at different heights and separated by gaps in the axial direction of the accommodating cavity (11), a light mixing area is enlarged and the degree of light mixing evenness is increased.
