Abstract

Provided is a lamp for a vehicle. The lamp includes: a first reflector disposed above an LED array and including an elliptical reflective surface that defines a first focal point and a second focal point; and a second reflector disposed below the LED array and including a parabolic reflective surface that defines a third focal point, and may increase an amount of light in a front region and a light width region of a vehicle by utilizing the existing light source without adding a separate light source.

First claim

What is claimed is:

1. A lamp for a vehicle, comprising:
a first reflector disposed entirely on a first side of an LED array and including an elliptical reflective surface that has a first focal point and a second focal point, the first reflector reflecting light emitted from the LED array, the first reflector being coupled to a module; and
a second reflector disposed on a second side of the LED array and including a parabolic reflective surface that has a third focal point, the second reflector reflecting the light reflected by the first reflector, the second side being opposite to the first side with respect to a line perpendicular to a surface of the LED array, the surface of the LED array being disposed on the module,
wherein the LED array includes:
a first array configured to produce a high beam; and
a second array disposed parallel to the first array and configured to produce a low beam, and

wherein the first focal point of the first reflector lies on a center of the second array.

2. The lamp of claim 1 , further comprising an aspherical lens, wherein the aspherical lens is provided in front of the LED array.

3. A lamp for a vehicle, comprising:
a first reflector disposed entirely on a first side of an LED array and including an elliptical reflective surface that has a first focal point and a second focal point, the first reflector reflecting light emitted from the LED array, the first reflector being coupled to a module; and
a second reflector including a planar reflective surface and disposed on a second side of the LED array, the second reflector reflecting the light by reflected the first reflector, the second side being opposite to the first side with respect to a line perpendicular to a surface of the LED array, the surface of the LED array being disposed on the module,
wherein the LED array includes:
a first array configured to produce a high beam; and
a second array disposed parallel to the first array and configured to produce a low beam, and

wherein the first focal point of the first reflector lies on a center of the second array.

4. The lamp of claim 3 , further comprising an aspherical lens, wherein the aspherical lens is provided in front of the LED array.

5. The lamp of claim 3 , wherein the LED array includes an LED chip, and wherein the elliptical reflective surface of the first reflector has a third focal point, the first and third focal points being spaced apart by a distance corresponding to a width of the LED chip.
