Abstract
Disclosed herein is a lens of an optical fiber lamp apparatus, which allow light to be entirely collected uniformly on an optical fiber when lighting using the optical fiber to minimize a difference in brightness for each optical fiber, improving quality of lighting through the optical fiber, and an optical fiber lamp apparatus having the same.
Claims18
A lens of an optical fiber lamp apparatus, the lens comprising:
- a first portion including:
- an incident portion having one side to which light from a light source is incident;
- and
- a first total reflector having a diameter increased toward a first side of the first total reflector from the incident portion disposed at a second side of the first total reflector, wherein the light irradiated from the light source is reflected to travel from the second side of the first total reflector toward the first side of the first total reflector;
- and
- a second portion including:
- a second total reflector extending from the first side of the first total reflector and having a diameter which is decreased from the first side of the first total reflector;
- and
- an exit portion facing optical fibers on one side of the second total reflector,
- wherein the light which is incident to the first portion and then reflected is guided through the second portion and the exit portion to be collected on the optical fibers, and
- wherein a total length of the first portion and the second portion is greater than twice or more and less than or equal to four times of a diameter of the exit portion of the second portion.

An optical fiber lamp apparatus, comprising:
- a light source configured to irradiate light;
- an optical fiber spaced from the light source and configured to irradiate the light to an outside of the optical fiber lamp apparatus when the light is incident on the optical fiber;
- and
- a lens mounted between the light source and the optical fiber,
- wherein the lens includes:
- a first portion having an incident portion, wherein the light from the light source is incident on a side of the incident portion, and a first total reflector having a diameter which is increased toward a first side of the first total reflector from the incident portion disposed at a second side of the first total reflector, wherein the light irradiated from the light source is reflected to travel toward the first side of the first total reflector from the second side of the first total reflector;
- and
- a second portion including a second total reflector disposing from the first side of the first total reflector and having a diameter which is decreased from the first side of the first total reflector, and an exit portion facing the optical fiber on a side of the second total reflector, guiding the light which is incident to the first portion and then reflected in the second portion to be collected on the optical fiber,
- wherein a total length of the first portion and the second portion is greater than twice or more and less than or equal to four times of a diameter of the exit portion of the second portion.
