Secondary light distribution structure of directional light source

Abstract

The present invention discloses a secondary light distribution structure of a directional light source comprises a lamp cup having a cone shape, wherein the lamp cup is provided with a lamp cap at an end having a smaller diameter, and the lamp cap is connected with the lamp cup; a reflective cup disposed in the lamp cup, an outer wall of the reflective cup fits into an inner wall of the lamp cup, an inner wall of the reflective cup is coated with a reflective layer, and a light source plate is attached to a bottom of the reflective cup; a power supply disposed between the reflective cup and the lamp cap, one end of the power supply is connected to the lamp cap, the other end of the power supply passes through the bottom of the reflective cup and is connected to the light source plate; and a lens structure fixed at the end of the lamp cup having a larger diameter. The invention has a reflector to have higher light distribution efficiency through a secondary light distribution structure, so as to obtain a desired light distribution.
