Lighting device with spherical modulator

A lighting device includes a light source, an optic holder, and a spherical modulator. The optical device fixing device is provided with a concave part and a shielding part surrounding the concave part. The bottom of the recessed portion has an opening. The spherical modulator has at least one material, and the refractive index of the material is in the range of 1.3 to 2.7. The optical device holder is located between the light source and the spherical modulator. The spherical modulator is disposed in the recess of the optical device holder and shields the opening. The light source provides light towards the opening, and the light source and the opening are arranged along the optical axis of the spherical modulator. 一种照明装置，其包括光源、光学器件固定器以及球型调制器。光学器件固定器具有凹陷部以及环绕凹陷部的遮蔽部。凹陷部的底部具有开口。球型调制器具有至少一种材料，且此材料的折射系数落在1.3至2.7的范围。光学器件固定器位于光源以及球型调制器之间。球型调制器配置于光学器件固定器的凹陷部并遮蔽开口。光源朝向开口的方向提供光，且光源以及开口沿着球型调制器的光轴排列。
