摘要： A vehicle lamp of a direct projection type is configured to control deflection of direct light from a light emitting surface 14A serving as a surface light source using a convex lens 12. A lower end edge of the light emitting surface 14A includes a first side 14A1 and a second side 14A2, each extending linearly so as to form an obtuse angle with each other in a front view of the lamp, a point of intersection thereof is positioned on a rear focal point F of the convex lens 12, and is disposed to face forward such that the first side 14A1 is disposed on a horizontal plane including an optical axis Ax. It is configured such that, using first and second lens portions 12Z1, 12Z2 of the convex lens 12 respectively, the light from the light emitting surface 14A is deflected and/or diffused in directions respectively parallel to the first side 14A1 and the second side 14A2. According to this vehicle lamp, it is possible to form a light distribution pattern having horizontal and oblique cutoff lines on an upper end portion thereof, while providing a degree of freedom for a light intensity distribution on the light distribution pattern and suppressing generation of great unevenness in light distribution on a road surface ahead of a vehicle.

摘要： A vehicle headlamp (1A, 1B, 1C) is provided which includes a light source (11), a projection lens (30) that is disposed in front of the light source (11) and which projects light from the light source (11) to the front, a first shield member (40) that is disposed near a rear focal point of the projection lens (30) and which can switch light distribution patterns between at least one of a right high beam light distribution pattern and a left high beam light distribution pattern in both of which light from the light source (11) is partially cut off and at least one of a normal high beam light distribution pattern in which no part of light from the light source (11) is cut off and a low beam pattern, and a second shield member (50) that is disposed in a position which is spaced by a predetermined distance forwards or rearwards away from the rear focal point of the projection lens (30) and which cuts off light of a high beam which illuminates an upper area.

摘要： A vehicle headlamp system (100) includes a plurality of shades (12a, 12b, 12c, 112a, 112b, 112c, 102, 106) and a shade control section (58). When a first shade is in an operative position, the first shade shields light from a light source (14) in a first light shielding area. When a second shade is in an operative position, the second shade shields the light in a second light shielding area. When observed from a front of the vehicle headlamp (210), the first light shielding area and the second light shielding area overlap each other in a common light shielding area. The shade control section (58) is configured to control a shade actuating section (29, 114) such that, when moving the first shade from the operative position to the retracted position and moving the second shade from the retracted position to the operative position to switch a light distribution pattern, the light is continuously shielded in the common light shielding area.
