摘要： A translucent member is arranged so as to cause light originating from an LED light source oriented toward the front of a lamp to enter the translucent member. Outgoing LED light that has entered the translucent member is reflected rearward by a front surface, and then the light is reflected forward by a rear surface, to thereby exit forward of the lamp from the translucent member. At that time, an area on the front surface located in the vicinity of an optical axis Ax is formed as a normal reflection section subjected to reflection surface treatment. The other area of the front surface is formed as an internal reflection section which causes the outgoing LED light to undergo internal reflection. A plurality of reflection elements are formed on the rear surface of the translucent member so as to cause the outgoing LED light reflected from the front surface to enter the internal reflection section at an incidence angle which is smaller than or equal to a critical angle.

摘要： Light from an LED light source, which is placed to be directed toward the front of a lamp, is incident on a translucent member, and the light that is transmitted through the translucent member is reflected by a reflector toward the front of the lamp. An internal reflection portion that internally reflects light which is incident on the translucent member at a small angle with respect to an optical axis of the LED light source, in a direction which is substantially perpendicular to the optical axis, and a refraction portion that refracts light which is incident at a large angle with respect to the optical axis, in a direction which is substantially perpendicular to the optical axis, are formed on the surface of the translucent member. The LED emitted light can be caused to be incident on a reflective surface of the reflector in the form of substantially parallel beams which are directed in a direction that is substantially perpendicular to the optical axis. The LED emitted light can be caused to be incident on the range extending even to the peripheral edge of the reflective surface, without increasing the depth of the reflector. The reflection due to the reflector can be easily controlled.

摘要： A vehicular lamp which radiates a light by indirect illumination using a plurality of LED light sources which has a thin structure while providing sufficient light output to the front of the lamp, even in the case where the lamp is mounted in a wrap-around portion of the vehicle body. Respective Fresnel lenses which form light from respective LED light sources into parallel light fluxes are arranged so as to align the directions of the parallel light fluxes upward, and the parallel light fluxes are then reflected toward the front of the lamp by a reflector. The reflector is separated into sub-reflectors for every area which the parallel light fluxes from the respective Fresnel lenses strike, and the sub-reflectors are arranged in a stepped configuration extending in a lateral direction of the reflector from the front of the lamp toward the rear of the lamp. Accordingly, it is possible to form the reflector so as to wrap around to the rear of the lamp while the reflected light from the respective sub-reflectors is radiated toward the front of the lamp.

摘要： A vehicular lamp radiating light emitted by LED light sources through indirect illumination and having uniform brightness. Light from LED light sources is directed upward into parallel beams by Fresnel lenses. The parallel beams are reflected in a frontward direction. A reflector is divided into sub reflectors that differ in height and angle of forward inclination The distance between each LED light source and a corresponding Fresnel lens increases in proportion to a decrease in height of a corresponding sub reflectors, and the intensity of the luminous flux impinging on each Fresnel lens decreases in proportion to a decrease in height of a corresponding sub reflectors. The intensity of luminous flux impinging on each sub reflectors decreases in proportion to a decrease in projected area in a forward direction of the lamp. The sub reflectors have uniform luminance and the entire reflecting surface appears uniform in brightness.

摘要： A vehicular lamp which radiates light by indirect illumination using a plurality of LED light sources and which has an improved appearance when the lamp is lit. Light from a plurality of LED light sources is formed into parallel light fluxes by a plurality of Fresnel lenses, and the parallel light fluxes are reflected toward the front of the lamp by a segmented reflector. The LED light sources and the lenses are divided into first and second groups which form respective light fluxes directed in orthogonal directions in a front view of the lamp. The reflecting surface of the reflector is divided into a plurality of segments, and first and second reflective elements, which reflect the parallel light fluxes from the respective lens groups, are provided in each of the segments. With this structure, a portion of all reflective elements can be seen brightly when viewing the lamp from a position directly in front of the lamp and within certain angular limits.

摘要： The shape of a horizontal cross section Sho including a reference axis Ax on a reflective surface 14a is set to a curved shape for focusing and reflecting light from a light source 12a closer to the reference axis Ax within the horizontal cross section Sho. The shape of a vertical cross section including the axis in the direction of emitting reflected light at each of the points on the horizontal cross section including the reference axis Ax on the reflective surface 14a is set to a curved shape for reflecting the light from the light source in substantially parallel to the axis in the direction of emitting the reflected light in a central reflective area near the lateral reference axis Ax. The shapes of peripheral reflective areas 14a2 on both sides of the central reflective area are respectively set to curved shapes for focusing and reflecting the light from the light source 12a closer to the axis in the direction of emitting the reflected light. It is thus possible to obtain a light distribution pattern with less nonuniformity in light and a substantially laterally long rectangular shape.
