Abstract
Provided are a light guide column, a luminaire, and a method for manufacturing a light guide column. The present disclosure relates to the field of lighting equipment. The light guide column includes a columnar structure. The columnar structure is made of a transparent material, an interior of the columnar structure includes at least one first annular region centered on an axis of the columnar structure, an interior of the first annular region has bubbles, and at least a portion of a luminous intensity distribution curve of the light guide column has a serrated pattern.
Claims20
A light guide column, comprising:
- a columnar structure, wherein the columnar structure is made of a transparent material, an interior of the columnar structure includes at least one first annular region centered on an axis of the columnar structure, an interior of the at least one first annular region has bubbles;
- and
- at least a portion of a luminous intensity distribution curve of the light guide column has a serrated pattern;
- a count of the at least one first annular region is two or more, and the bubbles include first bubbles and second bubbles;
- and
- an interior of one or more of the at least one first annular region has the first bubbles, and an interior of one or more remaining first annular regions has the second bubbles.
A method for manufacturing a light guide column, wherein the light guide column includes a columnar structure, the columnar structure is made of a transparent material, an interior of the columnar structure includes at least one first annular region centered on an axis of the columnar structure, and an interior of the at least one first annular region has bubbles;
- at least a portion of a luminous intensity distribution curve of the light guide column has a serrated pattern;
- and
- the method comprises:
- providing a light guide column material, wherein the light guide column material includes a material for forming the at least one first annular region, and the material includes a plastic material, a fast-acting foaming agent, and a slow-acting foaming agent;
- performing temperature control and pressure control on the light guide column material to form the bubbles inside the light guide column material;
- and
- performing cooling control on the light guide column material to cure the light guide column material, to obtain the light guide column.
