In the above, since one lens cut 91a corresponds to one LED lamp 80, when the emission color is the same and the tail lamp and the stop lamp which are different only in the brightness standard are used, the LED is used. The current applied to the lamp 80 must be changed, which causes a problem that the cost is increased, for example, an external power supply circuit is required.

There is also proposed means for turning on the LED lamp 80 of low luminance when used as a tail lamp, but in this case, at least one of the LED lamps 80 is arranged at an optimum position with respect to the lens cut 91a. This causes another problem that the display quality is deteriorated, such as causing uneven light emission in the lens 91, and cannot be an essential solution.

ランプ１に対して１対１で対応するレンズカット１１ａ
が設けられている。Next, according to the present invention, a configuration of a vehicle lamp 10 adapted to the above-described LED lamp 1 will be described. First, the vehicle lamp 10 is provided with a lens 11, and the lens 11 has an LED.
Lens cut 11a corresponding to lamp 1 on a one-to-one basis

均一に光り輝くものとなる。The lens cut 11a is, for example, a convex spherical surface, and refracts light emitted from the front LED chip 2 and emitted by the lens portion 4a at an appropriate emission angle α again. To give a new radiation angle β. Therefore, the radiation angle α when radiated from the lens portion 4a is set to cover the entire surface of the lens cut 11a, and the radiation angle β when radiated from the lens cut 11a is set to satisfy the light distribution characteristics. For example, when the surface of the lens 11 is viewed from the outside, the entire surface shines almost uniformly.

2, the main reflecting mirror 12 is provided on the first reflecting surface 5a.
Is formed as a paraboloid of revolution having substantially one focal point sf1. Therefore, light emitted from the rear LED chip 3 is reflected by the first reflecting surface 5a, and after being reflected by the main reflecting mirror 12, is incident on the lens cut 11a as substantially parallel rays. After being imaged once by the lens cut 11a, the light is emitted as diffused light having an emission angle γ.

満足するものと成る。Here, if the radiation angle γ is set to approximately 1.7 times (≒ √3 times) the radiation angle β, when the same LED chip is used, the brightness when the front LED chip 2 is turned on is increased. That is, three times the brightness when the rear LED chip 3 is turned on can be obtained, and this difference satisfies the specified brightness difference between the stop lamp and the tail lamp.

Is not always the same as the above calculation, but in any case, the prescribed difference in brightness can be provided based on the above principle.
