Abstract
Description
The present invention relates to a vehicle headlamp, and more particularly, to a vehicle headlamp that can improve the light efficiency of light irradiated from a light source.
In general, a vehicle lamp includes a head lamp installed at the front of the vehicle and a rear lamp installed at the rear of the vehicle.
The headlamp is a lamp that illuminates the front to illuminate the vehicle during night driving, and includes a fog light that makes it easy for other vehicles and pedestrians to recognize the vehicle in the event of snow, rain, and fog, and a direction indicator indicating the direction of the vehicle. .
The rear lamp includes a brake light that is turned on when the driver operates the brake, a rear light that is turned on when the vehicle reverses, and a direction indicator that informs the direction of travel of the vehicle.
Recently, various light sources such as LEDs have been applied to vehicle lamps, and include a light source for irradiating light and a reflector installed at the rear of the light source to reflect light emitted from the light source to the front.
The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.
The headlamp for a vehicle according to the prior art has a problem that the light efficiency of the light source is not good and the light distribution pattern is not good because the amount of light that is not irradiated to the front of the vehicle is lost when the light emitted from the light source is reflected forward by the reflector. There is this.
Therefore, there is a need for improvement.
SUMMARY OF THE INVENTION An object of the present invention is to provide a headlamp for a vehicle capable of securing a driver's field of view by allowing light emitted from a light source to be irradiated farther and diffused laterally.
The present invention to achieve the above object, the light source for irradiating light; And a reflector for reflecting forward the light emitted from the light source; The Z optical axis of the light source provides a headlamp for a vehicle, which is disposed to be spaced apart from the Z axis.
In addition, the Y optical axis of the light source of the present invention is characterized in that it is arranged to be spaced apart clockwise from the Y axis around the X axis.
In addition, the Y optical axis of the light source of the present invention is characterized in that disposed 1 to 5 degrees spaced apart in the clockwise direction from the Y axis around the X axis.
In addition, the Z optical axis of the light source of the present invention is characterized in that it is disposed clockwise spaced from the Z axis around the Y axis.
In addition, the Z optical axis of the light source of the present invention is characterized by being disposed 1 to 5 degrees in the clockwise direction from the Z axis around the Y axis.
In addition, the X optical axis of the light source of the present invention is characterized in that it is disposed clockwise from the X axis along a horizontal plane around the second focus of the reflector.
In addition, the X optical axis of the light source of the present invention is characterized in that disposed 1 to 5 degrees clockwise from the X axis along the horizontal plane around the second focus of the reflector.
Since the light source according to the present invention is disposed to be inclined to the rear and one side of the reflector, the light irradiated to the front of the vehicle through the lens is irradiated farther and wider in the lateral direction, thereby effectively securing the driver's field of view. .
