Abstract
An LED package has a light emitting element, a first optical section that is disposed around the light emitting element, and a second optical section that is disposed around the first optical while being separated from the first optical section. A gap is formed between the first and second optical sections. The gap allows part of light emitted from the light emitting element to be radiated from the first optical section as nearly parallel light converged in the direction perpendicular to the center axis of the light emitting element. The second optical section includes a reflection surface to reflect the nearly parallel light in the direction parallel to the center axis of the light emitting element.

A light emitting diode (LED) package, comprising:
- a light emitting element;
- a first optical section that is disposed around the light emitting element;
- and
- a second optical section that is disposed around the first optical section while being separated from the first optical section;
- wherein a gap is formed between the first and second optical sections, the gap allowing a part of light emitted from the light emitting element to be radiated from the first optical section as nearly parallel light converged in the direction perpendicular to the center axis of the light emitting element, and the second optical section includes a reflection surface to reflect the nearly parallel light in the direction parallel to the center axis of the light emitting element.
A light emitting diode (LED) package, comprising:
- a light emitting element;
- a first optical section that is disposed around the light emitting element;
- and
- a second optical section that is disposed around the first optical section, wherein the first and second optical sections are in contact with each other in a region of a range of about 45 degrees or less to the center axis of the light emitting element,
- wherein a gap is formed between the first and second optical sections, the gap allowing part of light emitted from the light emitting element to be radiated from the first optical section as nearly parallel light converged in a direction perpendicular to the center axis of the light emitting element, and the second optical section includes a reflection surface to reflect the nearly parallel light in the direction parallel to the center axis of the light emitting element.
A light emitting diode (LED) package, comprising:
- a light emitting element;
- a first optical section that is disposed around the light emitting element;
- and
- a second optical section that encloses the first optical section,
- wherein the first and second optical sections are in contact with each other in a region between about 45 degrees or less to the center axis of the light emitting element, and the center axis of the lighting element, and
- wherein a gap is formed between the first and second optical sections in a region between about 45 degrees or less to the center axis of the light emitting element, and 90 degrees to the center axis of the lighting element, the gap allowing a part of light emitted from the light emitting element to be radiated from the first optical section as nearly parallel light converged in a direction perpendicular to the center axis of the light emitting element, and the second optical section includes a reflection surface to reflect the nearly parallel light in the direction parallel to the center axis of the light emitting element.
