Abstract
A lamp shade includes a light permeable bottom layer and a light reflection structure provided on the light permeable bottom layer and including a plurality of reflective stripes formed and distributed on a surface of a side of the light permeable bottom layer and a plurality of recessed gaps formed between the reflective stripes and each located between any two adjacent reflective stripes. Each of the recessed gaps has a depth direction extending into a thickness direction of the light permeable bottom layer. Thus, the light patterns of the lamp shade will produce variations by provision of the reflective stripes and the recessed gaps of the light reflection structure, thereby enhancing the aesthetic quality of the lamp shade.

A lamp shade, comprising:
- a light permeable bottom layer;
- and
- a light reflection structure provided on the light permeable bottom layer and including:
- a plurality of reflective stripes formed and distributed on a surface of a side of the light permeable bottom layer;
- and
- a plurality of recessed gaps formed between the reflective stripes and each located between any two adjacent reflective stripes;
- wherein each of the recessed gaps has a depth direction extending into a thickness direction of the light permeable bottom layer, and the recessed gaps has a distribution density of about five to eight (5 to 8) pieces per millimeter (mm) width.
A lamp shade, comprising:
- a light permeable bottom layer;
- and
- a light reflection structure provided on the light permeable bottom layer and including:
- a plurality of reflective stripes formed and distributed on a surface of a side of the light permeable bottom layer;
- and
- a plurality of recessed gaps formed between the reflective stripes and each located between any two adjacent reflective stripes;
- wherein each of the recessed gaps has a depth direction extending into a thickness direction of the light permeable bottom layer, and each of the recessed gaps has a depth of about 0.01 to 0.05 millimeter (mm).
A lamp shade, comprising:
- a light permeable bottom layer;
- and
- a light reflection structure provided on the light permeable bottom layer and including:
- a plurality of reflective stripes formed and distributed on a surface of a side of the light permeable bottom layer;
- and
- a plurality of recessed gaps formed between the reflective stripes and each located between any two adjacent reflective stripes, wherein:
- each of the recessed gaps has a depth direction extending into a thickness direction of the light permeable bottom layer;
- each of the recessed gaps has a first side and a second side opposite to the first side;
- the first side of each of the recessed gaps has a first normal line;
- and
- the second side of each of the recessed gaps has a second normal line which is not parallel with the first normal line of the first side.
A method for forming reflective stripes on a surface of a lamp shade, comprising:
- preparing a bottom layer that is made of light permeable material;
- forming a reflective plated layer on a surface of the bottom layer by a plating process;
- and
- applying a force to press the plated layer by a cutting tool which has predetermined patterns and stripes to form a plurality of reflective stripes and a plurality of recessed gaps on the plated layer, wherein each of the recessed gaps is located between any two adjacent reflective stripes and has a depth extending into the bottom layer.
