Abstract
The present invention relates to a rear combination lamp of a vehicle, comprising: a light guide panel (LGP) having a light diffusion pattern printed on a rear surface thereof; At least one LED for rear light, which is located at the side of the light guide panel, in which irradiated light is totally reflected in the light diffusion pattern and diverted forward; At least one LED for brake lights positioned at the rear of the light guide panel; Located at the rear of the light guide panel, characterized in that it comprises a brake lamp reflecting member for reflecting the light emitted from the LED for the brake lamp to the front.
As a result, a rear light having a low light distribution value and a braking light having a high light distribution value can be simultaneously implemented using the light guide panel, thereby improving design freedom.
Description
The present invention relates to a rear combination lamp of a vehicle, and more particularly, to a rear combination lamp of a vehicle that can implement a taillight region and a braking lamp region together.
In general, a combination lamp is detachably mounted at the front and the rear of the vehicle, which informs the driver of the front and subsequent vehicles of their driving intentions during the night driving so that they can drive safely. The driver of other vehicles of the vehicle can be identified to allow defensive driving.
In particular, the rear combination lamp mounted on the left / right side of the rear of the vehicle incorporates a reversing light, a tail light and a braking light, and a turn signal.
1 is a photograph showing a state in which the LED for the rear light is turned on in the rear combination lamp of a conventional vehicle, Figure 2 is a cross-sectional view taken along the line XX of Figure 1, showing a path of light irradiated from the LED for the rear light of Figure 1 schematically. .

Accordingly, an object of the present invention is to provide a rear combination lamp of a vehicle that can implement a rear light having a low light distribution value and a braking light having a high light distribution value at the same time by using a light guide panel.
According to the rear combination lamp of the vehicle of the present invention, the object is a light guide panel (LGP, Light Guide Panel) printed with a light diffusion pattern on the back; At least one LED for rear light, which is located at the side of the light guide panel, in which irradiated light is totally reflected in the light diffusion pattern and diverted forward; At least one LED for brake lights positioned at the rear of the light guide panel; The light guide panel is located behind the light guide panel, and the light emitted from the LED light for the braking lamp reflecting member is achieved by the front.
Here, when the tail light LED is turned on, the light irradiated from the tail light LED flows along the light guide panel, and is totally reflected in the light diffusion pattern to diverge forward, and when the brake light LED is turned on, from the LED for the brake light It is preferable that the irradiated light is emitted forward through the defect-free area of the light guide panel on which the light diffusion pattern is not printed after being reflected by the reflective member for the brake lamp.
The LED for the brake lamp is disposed so that the irradiation direction of the light from the top to the bottom, the reflective member for the brake lamp is preferably located below the LED for the brake lamp.
In this case, the light guide panel is made of an acrylic material, the light diffusion pattern is preferably laser processed on the back of the light guide panel.
As described above, according to the present invention, a rear combination lamp of a vehicle in which a rear light having a low light distribution value and a braking light having a high light distribution value can be simultaneously implemented using a light guide panel, thereby improving design freedom.
