Disclosed is a multi-combination downlight, comprising a cavity, a light-emitting component, an inner cavity reflector, an outer reflector (101) and a face mask, wherein the light-emitting component, the inner cavity reflector and the outer reflector (101) are arranged in the cavity, the light-emitting component is arranged in a light inlet of the inner cavity reflector, the diameter of a light inlet of the outer reflector (101) is the same as the diameter of a light outlet of the inner cavity reflector and the two are connected, and the arc face of the side face of the inner cavity reflector is designed to be a paraboloid which enables light emitted from a geometric centre point of a light source and light emitted from the inner cavity reflector to be parallel to each other. In the present invention, principally with the design of the inner cavity reflector of the downlight, combined with a transparent face mask with high transmittance and a low dispersive angle, and by utilizing different surface processing modes of the reflectors, batwing, water droplet shaped, inverted triangle and Lambert type light distribution can be obtained; and a diffuser plate is placed in the front, the same light distribution angle or the uniform effect of a light-emitting face mask can be obtained built-in by utilizing different combination modes. |
