Helmet with hidden light source and method for manufacturing same

1. A method for manufacturing a helmet with a hidden light source, comprising:

providing a transparent base film and a screen printing plate, wherein the base film comprises a first portion and a second portion, and the screen printing plate covers and corresponds to the first portion;

printing a lightproof ink layer on the second portion and the screen printing plate;

removing the screen printing plate;

coating a light transmitting ink layer on the lightproof ink layer;

attaching at least one light source on the light transmitting ink layer corresponding to the first portion; and

forming a helmet base to cover the at least one light source.

2. The method for manufacturing a helmet with a hidden light source of claim 1 , wherein the step of printing a lightproof ink layer comprises distributing lightproof ink material on the second portion and the screen printing plate and then squeegeeing from one side of the base film to another side of the base film.

3. The method for manufacturing a helmet with a hidden light source of claim 1 , wherein the base film, the lightproof ink layer, and the light transmitting layer are deformed to be helmet shaped by thermoforming technology before or after the step of attaching at least one light source.

4. A helmet with a hidden light source, comprising:

a helmet housing comprising a transparent base film, a lightproof ink layer and a light transmitting ink layer in sequence, wherein the base film comprises a first portion and an adjacent second portion, the lightproof ink layer comprises a mesh-like third portion corresponding to the first portion and a fourth portion corresponding to the second portion;

at least one light source attached on the light transmitting ink layer and corresponding to the mesh-like third portion; and

a helmet base covering the at least one light source and the light transmitting ink layer.

5. The helmet with a hidden light source of claim 4 , wherein the at least one light source comprises a plurality of light sources arranged along a line.

6. The helmet with a hidden light source of claim 5 , wherein a plurality of diffusion structures corresponding to light sources one by one are formed at the base film of the helmet housing.

7. The helmet with a hidden light source of claim 6 , wherein each diffusion structure includes a protruding portion, which defines a convex surface and an annular groove surrounding the convex surface.

8. A helmet with a hidden light source, comprising:

a helmet housing comprising a transparent base film, a lightproof ink layer and a light transmitting ink layer in sequence, wherein the base film comprises a plurality of first portions and a second portion, the lightproof ink layer comprises a plurality of mesh-like third portions corresponding to the first portions one by one and a fourth portion corresponding to the second portion;

a plurality of light sources attached on the light transmitting ink layer, wherein each third portion corresponds to at least one light source; and

a helmet base covering the light sources and the light transmitting ink layer.

9. The helmet with a hidden light source of claim 8 , wherein the third portions correspond to the light sources one by one.

10. A helmet with a hidden light source, comprising:

a helmet housing comprising a transparent base film, a lightproof ink layer and a light transmitting ink layer in sequence, wherein the base film comprises a first portions and a second portion, wherein the lightproof ink layer comprises a mesh-like third portion corresponding to the first portion and a fourth portion corresponding to the second portion, wherein the helmet housing has a light transmitting portion and a lightproof portion, the light transmitting portion is consisted of the first portion, the third portion, and portion of the light transmitting layer, and the lightproof portion is consisted of the second portion, the fourth portion, and the other portions of the light transmitting layer;

a plurality of light sources attached on the light transmitting portion; and

a helmet base covering the light sources and the light transmitting ink layer.
