Abstract

A light emitting diode (LED) for automotive lamp is described. The LED has a cross-axis symmetrical optical structure on a light emitting path. When the LED emits light, a light form of the light assumes a symmetrical cross-axis distribution due to the optical structure.

Claims

1. A light emitting diode (LED) for an automotive lamp, comprising:

a support, having a reflection accommodation area;

a chip, planted in the reflection accommodation area; and

a molding compound, covering the chip,

wherein the LED has a cross-axis symmetrical optical structure on a light emitting path.

2. The LED for an automotive lamp as claimed in claim 1, wherein the molding compound is a cross-axis symmetrical optical structure, when the LED emits light, the light passes through the optical structure of the molding compound, such that a light form of the light assumes a cross-axis distribution.

3. The LED for an automotive lamp as claimed in claim 1, wherein the reflection accommodation area is a cross-axis symmetrical optical structure, when the LED emits light, the light form of the light assumes a cross-axis distribution due to the optical structure of the reflection accommodation area.

5. The LED for an automotive lamp as claimed in claim 2, wherein two ends of an axis of the optical structure are in the same shape.

6. The LED for an automotive lamp as claimed in claim 5, wherein the two ends of the axis optical structure are in an arc shape, a triangular shape, or a square shape.

4. The LED for an automotive lamp as claimed in 1, wherein the LED is a Through-Hole LED, a SuperFlux LED, or Top LED.

7. A light emitting diode (LED) for an automotive lamp, comprising:

a support, having a reflection accommodation area;

a chip, planted in the reflection accommodation area; and

a molding compound, covering the chip,

wherein the molding compound has a cross-axis symmetrical optical structure, when the LED emits light, the light passes through the optical structure of the molding compound, such that a light form of he light assumes a cross-axis distribution.

8. The LED for an automotive lamp as claimed in claim 7, wherein the LED is a Through-Hole LED, a SuperFlux LED, or a Top LED.

9. The LED for an automotive lamp as claimed in claim 7, wherein two ends of an axis of the optical structure are in the same shape.

10. The LED for an automotive lamp as claimed in claim 9, wherein the two ends of the axis of the optical structure are in an arc shape, a triangular shape, or a square shape.

11. A light emitting diode (LED) for automotive lamp, comprising:

a support, having a reflection accommodation area;

a chip, planted in the reflection accommodation area; and

a molding compound, covering the chip,

wherein the reflection accommodation area has a cross-axis symmetrical optical structure, when the LED emits light, a light form of the light assumes a cross-axis distribution due to the optical structure of the reflection accommodation area.

12. The LED for an automotive lamp as claimed in claim 11, wherein the LED is a Through-Hole LED, a SuperFlux LED, or a Top LED.

13. The LED for an automotive lamp as claimed in claim 11, wherein two ends of an axis of the optical structure are in the same shape.

14. The LED for an automotive lamp as claimed in claim 13, wherein the two ends of the axis of the optical structure are in an arc shape, a triangular shape, or a square shape.
