Abstract
An exemplary light pipe includes a main pipe and branch pipes. The main pipe includes a light inputting segment, an end portion, and a light outputting segment between the light inputting segment and the end portion. The light inputting segment includes connecting openings defined therein. A distance between each connecting opening and the end portion of the main pipe is different from a distance between each other connecting opening and the end portion of the main pipe. The branch pipes connect with the light inputting segment at the respective connecting openings.
Claims19
A light pipe comprising:
- a main pipe, the main pipe comprising:
- a light inputting segment, the light inputting segment having a plurality of connecting openings defined therein;
- an end portion;
- and
- a light outputting segment between the light inputting segment and the end portion, a distance between each connecting opening and the end portion being different from a distance between each other connecting opening and the end portion;
- and
- a plurality of branch pipes connecting with the light inputting segment at the connecting openings, respectively.
A light guiding device comprising:
- a light pipe, the light pipe comprising:
- a main pipe, the main pipe comprising:
- a light inputting segment, the light inputting segment having a plurality of connecting openings defined therein;
- an end portion;
- and
- a light outputting segment between the light inputting segment and the end portion, a distance between each connecting opening and the end portion being different from a distance between each other connecting opening and the end portion;
- and
- a plurality of branch pipes, the branch pipes connecting with the light inputting segment at the connecting openings, respectively;
- and
- a plurality of light sources having brightness output capabilities that are different from each other, the light source with the highest brightness output capability being attached to the branch pipe farthest away from the light outputting segment, and the light source with the lowest brightness output capability being attached to the branch pipe nearest to the light outputting segment, the branch pipes capable of guiding light emitted by the light sources to the light outputting segment.
A light guiding device comprising:
- a light pipe, the light pipe comprising:
- a main pipe, the main pipe comprising:
- a light inputting segment, the light inputting segment having a plurality of connecting openings defined therein;
- an end portion;
- and
- a light outputting segment between the light inputting segment and the end portion, a distance between each connecting opening and the end portion being different from a distance between each other connecting opening and the end portion;
- and
- a plurality of branch pipes, the branch pipes connecting with the light inputting segment at the connecting openings, respectively;
- and
- a plurality of light sources, the light sources being attached to ends of the branch pipes, respectively,
- wherein each of the light sources has a different luminosity from each other light source, and the luminosities of the light sources increase with increasing distance of the corresponding connecting openings from the end portion.
