Vehicle lamp

1. A vehicle lamp comprising:

a light source part having a semiconductor-type light source;

a second lens having a second lens part which is disposed at a front side of the light source; and

a first lens disposed between the light source and the second lens and having a first lens part to convert a light cone of the light source to a cone which connects the second lens part and a basic focal point of the second lens part to each other,

wherein the first lens part is formed to inwardly convert and radiate light from the light source allowed to enter an incident surface outside in a horizontal direction of the first lens part so as to be allowed to enter an incident surface outside a horizontal direction of the second lens part, and

wherein in a case where a cutout is present at a part of a light emitting chip which is provided at the light source, the light emitting chip is disposed so that a cut out portion is positioned at a lower side in a vertical direction.

2. The vehicle lamp unit according to claim 1 , wherein the second lens part is formed so as to radiate light from outside to inside from a central side towards outside in a horizontal direction.

3. The vehicle lamp unit according to claim 1 , wherein an incident surface in a range in a vertical direction of the first lens part, in which an irradiation angle of light from the light source is a predetermined angle or less with reference to a light source optical axis of the light source, is formed so that a focal point position of the second lens part is shifted in a vertical direction with respect to the basic focal point of the second lens part.

4. The vehicle lamp unit according to claim 1 , wherein

the first lens part has a backward focal distance of 3 mm or more and 10 mm or less,

the first lens is formed of a material with a higher heat resistivity than a material for the second lens, and

the first lens is disposed so that a light emission center of the light source part is positioned at or near a backward focal point of the first lens part.

5. The vehicle lamp unit according to claim 1 , wherein the second lens is formed of an acrylic resin.

6. The vehicle lamp unit according to claim 1 , wherein

at the light source part, a plurality of light emitting chips are provided,

at the first lens, the first lens part that corresponds to a respective one of the light emitting chips is formed in plurality, and

at the second lens as well, the second lens part that corresponds to a respective one of the light emitting chips is formed in plurality.

7. The vehicle lamp unit according to claim 6 , comprising a lamp unit for low beam, which is disposed outside of a vehicle, wherein

the light emitting chips, the first lens part, and the second lens part are disposed so as to be arranged in a vertical direction at positions adjacent to the lamp unit for low beam at the inside of the vehicle.

8. A vehicle lamp comprising:

a light source part having a semiconductor-type light source;

a second lens having a second lens part which is disposed at a front side of the light source; and

a first lens disposed between the light source and the second lens and having a first lens part to convert a light cone of the light source to a cone which connects the second lens part and a basic focal point of the second lens part to each other,

wherein the first lens part is formed to inwardly convert and radiate light from the light source allowed to enter an incident surface outside in a horizontal direction of the first lens part so as to be allowed to enter an incident surface outside a horizontal direction of the second lens part, and

wherein the semiconductor-type light source includes a light emitting chip, the light emitting chip including a light emitting chip having a cutout at a part thereof, and the light source part being arranged such that as to the light emitting chip having a cutout at a part thereof, the light emitting chip is disposed so that a cut out portion is positioned at a lower side in a vertical direction.
