Abstract
The present invention discloses a multiple light distribution structure of a directional light source, which comprises a reflective cup having a bowl shape, an inner wall of the reflective cup being coated with a reflective layer; a light source plate disposed inside the reflective cup, the light source plate being fixed to a bottom of the reflective cup by means of a plurality of screws, and the light source plate having a plurality of light emitting units which are provided thereon; a lens facing the light source plate, the lens having a plurality of lens units which are provided thereon, each of the plurality of lens units facing one of the plurality of light emitting units; and a multi-point lens, covering on the reflective cup. Owning to multiple light distributions performed through the reflective cup, the lens and the multi-point lens, light in the beam angle may be evenly distributed.
