A linear regulator (40) supplies a first drive current (I1) to a first light source (24) in a first period in which the first light source (24) is turned on and a second light source (25) is not turned on, and in a second period in which the first light source (24) and the second light source (25) are turned on, and stops the supply of the first drive current (I1) in a third period in which the first light source (24) and the second light source (25) are turned off. A switching regulator (41) supplies a second drive current (I2) to the second light source (25) in the second period, and stops the supply of the second drive current (I2) in the third period.

To provide a vehicular lamp that can improve the degree of freedom in the arrangement position of a road surface irradiation unit. The vehicular lamp comprises a road surface irradiation unit for forming an irradiation pattern around the vehicle with light from a light emitting portion for a road surface; and a shielding part for covering the light emitting portion for the road surface when the road surface irradiation unit is viewed from the front. The vehicular lamp may further comprise a lamp unit housed in a lamp chamber together with the road surface irradiation unit, and the road surface irradiation unit may be turned on and off interlocked with the lamp unit.

The present invention may include a replaceable vehicle light including a lamp body, a printed circuit board (pcb) supported by the lamp body, and the pcb may include a plurality of individual lights arranged in a radial pattern. A controller chip may be included on the pcb, the controller chip may provide electrical energy to each of the individual lights, thereby enabling selective illumination of each of the individual lights. The controller chip may provide a lighting designation, wherein some of the individual lights are designated as primary lights being illuminated at a first brightness, which may illuminate in a radial pattern. The radial pattern may provide a more visible pattern which may be more distinguishable from other roadway lighting, thereby increasing visibility of the replaceable vehicle light.

A rear light unit of a vehicle is provided. The rear light unit includes an array of first light sources, arranged angularly offset along a first inner circumferential arrangement region, and an array of second light sources, arranged angularly offset at least along a second outer circumferential arrangement region concentric to the first inner circumferential arrangement region of the first light sources. The first and second light sources are made by one or more light-emitting diodes with which a light diffusing body is associated, the first light sources having a diffuser body in the form of a prismatic pinnacle, and the second light sources having a blade-shaped diffuser body along whose median axis emerges orthogonally a septum which enters the first inner circumferential arrangement region of the first light sources according to radial directions inserted between two successive light sources.

The invention relates to a motorcycle lamp (2) for implementing at least one lamp function. The motorcycle lamp (2) comprises a housing (4) having a light-emission aperture (6), a bracket (8) mounted on the housing (4) for securing the motorcycle lamp (2) to a motorcycle, at least one light source (10) disposed in the housing (4) and a front optics (12) made of a solid transparent material disposed between the at least one light source (10) and the light-emission aperture (6), wherein the at least one light source (10) comprises an LED and is disposed and oriented in the housing (4) such that it emits light in a main radiation direction (14) extending through the light-emission aperture (6), and wherein the front optics (12) closes the light-emission aperture (6) and deflects and shapes the light emitted by the at least one light source (10) to generate a light distribution corresponding to a lamp function implemented by the motorcycle lamp (2). In order for the lamp (2) to improve the lateral perceptibility without the use of additional optical elements in the optical path, it is proposed that a light-emission surface (16) of the front optics (12) has a first convex curvature when viewed in a horizontal plane (yz) and a second convex curvature when viewed in a vertical plane (xz), the latter being smaller than the first convex curvature in the horizontal plane (yz) or flat.
