Abstract

The present disclosure provides a technology of achieving a compact configuration of efficiently guiding a light incident on an incident portion to an emitting portion. The vehicle lamp includes a light guide lens. The light guide lens includes an incident portion on which light is incident from the LEDs, an emitting portion which emits the incident light, and a main body portion which guides the light from the incident portion to the emitting portion. The incident portion has a larger width than the main body portion, and the emitting portion has a larger width than the main body portion.

Claims (18)

1. A vehicle lamp comprising:

a light guide body,

wherein the light guide body includes:

an incident portion on which light is incident from a light source;

an emitting portion which emits the incident; and

a main body portion which guides the light from the incident portion to the emitting portion,

wherein a width of a cross-section of the incident portion in a first direction is larger than a width of a cross-section of the main body portion in the first direction, and a width of a cross-section of the emitting portion in the first direction is larger than a width of a cross-section of the main body portion in the first direction, and

a width of a cross-section of the incident portion in a second direction crossing first direction is larger than a width of a cross-section of the main body portion in the second direction, and a width of a cross-section of the emitting portion in the second direction is smaller than a width of a cross-section of the main body portion in the second direction.

2. The vehicle lamp of claim 1 , wherein a cross-sectional area of the incident portion is larger than a cross-sectional area of the main body portion, and

a cross-sectional area of the emitting portion is larger than the cross-sectional area of the main body portion.

3. The vehicle lamp of claim 1 , wherein the emitting portion includes a reflective surface on an extension line of the main body portion, the reflective surface being configured to perform reflection in the second direction.

4. The vehicle lamp of claim 1 , wherein the incident portion has a shape which condenses the incident light to the main body portion.

5. The vehicle lamp of claim 2 , wherein the incident portion has a shape which condenses the incident light to the main body portion.

6. The vehicle lamp of claim 3 , wherein the incident portion has a shape which condenses the incident light to the main body portion.

7. The vehicle lamp of claim 1 , wherein the main body portion has a maximum width of 5 mm.

8. The vehicle lamp of claim 2 , wherein the main body portion has a maximum width of 5 mm.

9. The vehicle lamp of claim 3 , wherein the main body portion has a maximum width of 5 mm.

10. The vehicle lamp of claim 4 , wherein the main body portion has a maximum width of 5 mm.
