AUTOMOTIVE LAMP AND METHOD OF CONTROLLING THE SAME
First Claim
1. An automotive lamp, comprising:
- a light irradiation device configured to form a first pattern and a second pattern that at least partially overlap each other by irradiating light; and
a control device configured to adjust the light irradiation device to form a shadow area at a position of a second vehicle when the second vehicle exists in an area of a beam pattern in which the first pattern and the second pattern are synthesized with each other,wherein the control device is configured to determine a size of the shadow area by referring to whether the second vehicle exists in a non-uniform overlap section, in which the first pattern and the second pattern overlap each other to a non-uniform degree, in an irradiation section of the light.

Abstract
An automotive lamp which reduces dazzle to the drivers of other vehicles by adjusting a light pattern of irradiated light and a method of adjusting the automotive lamp is provided. An automotive lamp includes a light irradiation device which forms first and second patterns at least partially overlapping each other by irradiating light and a control device configured to adjust light irradiation device to form a shadow area at a position of a second vehicle when the second vehicle exists in an area of a beam pattern in which the first and second patterns are synthesized with each other. The control device is configured to determine a size of the shadow area by referring to whether the second vehicle exists in a non-uniform overlap section, in which the first pattern and the second pattern overlap each other to a non-uniform degree in an irradiation section of the light.

9. A method of controlling an automotive lamp, comprising:
-
forming, by a controller, a first pattern and a second pattern, which at least partially overlap each other, by irradiating light; determining, by the controller, whether a second vehicle exists in an area of a beam pattern in which the first pattern and the second pattern are synthesized with each other; and forming, by the controller, a shadow area at a position of the second vehicle by adjusting a light irradiation device based on the determination result, wherein the forming of the shadow area includes setting a size of the shadow area by determining whether the second vehicle exists in a non-uniform overlap section, when the first pattern and the second pattern overlap each other to a non-uniform degree in an irradiation section of the light. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
