Lamp For Vehicle And Method For Controlling The Same
A vehicle lamp includes: a light source unit including one or more light sources and configured to generate light; a reflector configured to reflect at least part of the light generated by the light source unit; and a lens configured to transmit therethrough a first portion of the light that is generated by the light source unit and that is reflected by the reflector to the lens. The reflector includes: a reflective part configured to reflect, to the lens, the first portion of the light generated by the light source unit; and a non-reflective part configured not to reflect, to the lens, the light generated by the light source unit. The reflective part and the non-reflective part of the reflector are configured to selectively reflect the light generated by the light source unit towards the lens to output a light distribution pattern from the vehicle lamp.
Lighting apparatus, automobile, and projection lens
A lighting apparatus includes: a projection lens; a light source behind the projection lens; a reflector that reflects light from the light source toward the projection lens; and a shield that blocks a portion of the light reflected by the reflector to form a cutoff line in a distribution pattern of the light. A textured section demarcated by unit regions is formed on a surface of the projection lens, and when a region in a center of the projection lens is defined as a central region, and regions left and right of the central region are defined as left and right regions, respectively, in a front view, a proportion of the unit regions in the central region is greater than a proportion of the unit regions in each of the left region and the right region.
VEHICLE HEADLAMP
A present invention is equipped with a semiconductor light source, a reflector, and a projection lens. The reflector comprises a first reflective surface and a second reflective surface. The first reflective surface comprises a first focal point and a second focal point positioned near a lens focal point. The second reflective surface comprises a first focal point and a second focal point positioned on a light-emitting surface side relative to the lens focal point. As a result, the present invention provides a high beam light distribution pattern having a hot zone in the center.
Vehicle lamp
In a vehicle lamp in which a plurality of lamp units is arranged side by side in a direction intersecting with a lamp longitudinal direction, a central luminous intensity of a light distribution pattern is increased while securing a sufficient irradiation light quantity. A first additional reflector 34A configured to reflect the light from a second light emitting element 22B toward the front is disposed in the vicinity of a front end edge 24A1 of a first reflector 24A.

Light emitting module with lens
A light emitting module includes a reflector, a lens and a light source disposed in the reflector. The lens is disposed in front of the reflector to refract light forwards so that the illuminating area of the light emitting module is adjustable. The light emitting module is particularly suitable for head light of vehicles. The light emitting module has a high illuminating efficiency and prevent light from dazzling a driver's eyes.
Lighting apparatus and mobile object including the same
A lighting apparatus to be installed on a mobile object includes: a heat dissipator having a first outer surface and a second outer surface different from the first outer surface; a first light-emitting device thermally coupled to the first outer surface of the heat dissipator; a second light-emitting device thermally coupled to the second outer surface of the heat dissipator; a reflector that reflects light emitted from the first light-emitting device; a first lens that is disposed in a path of light reflected by the reflector and that transmits the light from the reflector along a predetermined lighting direction; and a second lens disposed in a path of light from the second light-emitting device.
Head lamp for vehicle
A head lamp includes a plate-shaped base supported in a housing. A first light source is disposed on an upper surface of the base. A second light source is disposed on a lower surface of the base. An upper reflector extends from the upper surface of the base and is configured to reflect incident light emitted from the first light source in a forward direction. A lower reflector extends from the lower surface of the base and is configured to reflect light emitted from the second light source in the forward direction. A shield main body extends from an end of the base and is configured to: block a portion of light reflected from the upper reflector and the lower reflector, and form a beam pattern. A shield protrusion protrudes from the shield main body and is configured to block another portion of the light reflected by the lower reflector.
Vehicle lamp structure
Disclosed is a vehicle lamp structure including a lamp cup structure and a light-emitting structure. The lamp cup structure has a first light-reflecting surface and a second light-reflecting surface. The first light-reflecting surface has a first focal point and a second focal point. The second light-reflecting surface has a third focal point and a fourth focal point. The light-emitting structure includes a first light-emitting element and a second light-emitting element. The first light-emitting element corresponds to the first focal point. The second light-emitting element corresponds to the third focal point. The first light-emitting element generates a first light source projected onto the first light-reflecting surface to form a first reflection light source through the second focal point. The second light-emitting element generates a second light source projected onto the second light-reflecting surface to form a second reflection light source through the fourth focal point.
