Reflector assembly using multi-light-source for changing illumination effect

A reflector assembly using a multi-light-source for changing illumination effect, wherein the reflector assembly comprises a reflector cup (1), a first light source (2) and a plurality of second light sources (3), the first light source (2) and the second light sources (3) are independently controlled from each other, the plurality of the second light sources (3) are arranged around the first light source (2), the reflector cup (1) has a light inlet (11) and a light outlet (12), and the first light source (2) and the second light sources (3) are located in the light inlet (11), a reflective curved surface (13) for reflecting light rays emitted by the first light source (2) and the second light sources (2) is formed at an inner wall surface of the reflector cup (1);

• when the first light source (2) and the second light sources (3) are turned on simultaneously, the light rays emitted by the first light source (2) forms a first light spot (4) through the light outlet (12), and the light rays emitted by the second light sources (3) forms a second light spot (5) through the light outlet (12);
• an interval region (6) is formed between the first light spot (4) and the second light spot (5), and a microstructured reflective part (7) for reflecting part of the light rays emitted by the first light source (2) or/and the second light sources (3) towards the interval region (6) is formed on the reflective curved surface (13) along circumference of the reflective curved surface (13);
• wherein the microstructured reflective part (7) is distributed in a shape of an annular band on the reflective curved surface (13), and the microstructured reflective part (7) comprises several rings of spherical base circles (71) formed on the reflective curved surface (13);
• and
• wherein the microstructured reflective part (7) extends from a position of the light inlet (11) towards a direction of the light outlet (12) to a middle position of the reflective curved surface (13), and a vertical height between the microstructured reflective part (7) and the light inlet (11) is P, wherein P=h*0.6*tan 30° and h represents a height of the reflector cup.
