摘要： A vehicular lamp with an LED light source in which the translucent member includes a pillar-shaped portion that has at its rear end a condenser lens portion and at its front end a substantially bowl-configured parallel translation controlling portion. Light from the LED light source is formed into parallel light fluxes by the condenser lens portion, and this parallel light fluxes strike the pillar-shaped portion, and then the light path of the parallel light fluxes is formed into a crank configuration in a direction in which the light path separates from the axis of the pillar-shaped portion, thus allowing the reflected light from the parallel translation controlling portion to be resulted in parallel light fluxes that travels toward the front of the lamp and allowing the translucent member to appear to be lit uniformly

摘要： A vehicular lamp with an LED light source in which light from the LED light source is formed into parallel light fluxes by an optical member, and the parallel light fluxes are reflected by a reflector in the forward direction of the lamp. The bottom-face wall of the lamp body that houses the reflector has a translucent portion, and the LED light source and the optical member are disposed outside the translucent portion so that they are unrecognizable. The reflector is formed by a translucent member and is provided at a distance from the translucent portion of the lamp body and from the rear-face wall of the reflector, so that the parallel light fluxes from the optical member is subject to internal reflection.

摘要： A vehicular lamp which irradiates a light by means of indirect illumination employing an LED light source and having an improved appearance when the lamp is lit. Light from an LED light source is formed into an upward parallel light flux by a Fresnel lens and reflected toward the front of a lamp by a reflector. The reflecting surface of the reflector is formed in a stepped shape by providing a reflective element and a step portion in each of a plurality of segments which are sectioned at a uniform interval in a vertical direction. The width in the longitudinal direction of the lamp of each of the reflective elements is gradually increased as the distance of the reflective elements increases from the intersection of the central axis of the parallel light flux and the reflecting surface. Accordingly, the incident light flux is made substantially constant among all the reflective elements, and hence the brightness of the light emitted by the lamp is made uniform.

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： A vehicle lamp is constructed such that light exiting from an LED light source is converted into collimated light and such that the collimated light is reflected forward of the lamp by means of a reflector. At that time, the reflector portion has a stepwise reflection surface in which there are alternately formed a plurality of light incidence sections into which the collimated light enter and a plurality of intermediate sections into which no collimated light enters. Further, each of the intermediate sections is formed from an irregular surface formed so as to recess rearward of the lamp with respect to a plane parallel to the direction of radiation of the collimated light. By means of the irregular surface, stray light or the like included in the collimated light exiting from the optical member is reflected forward of the lamp. As a result, when the lamp is viewed from the front, the light incidence sections appear to glare, resembling spread spots, and the intermediate sections also appear to glare.

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 light emitted by LED light sources through indirect illumination and which has uniform brightness. Light emitted from the LED light sources is directed upward and formed into parallel beams by Fresnel lenses, and the parallel beams are reflected by a reflector in a frontward direction of the lamp. The reflector is divided into sub reflectors that differ in height and angle of forward inclination according to the areas on which the parallel light beams impinge. The distance between each of the LED light sources and the corresponding one of the Fresnel lenses increases in proportion to a decrease in the height of the corresponding one of the sub reflectors, and the intensity of the luminous flux impinging on each of the Fresnel lenses decreases in proportion to the decrease in the height of the corresponding one of the sub reflectors. Hence, the intensity of the luminous flux impinging on the reflecting surface of each of the sub reflectors decreases in proportion to the decrease in the projected area in the forward direction of the lamp, and thus the sub reflectors have a uniform luminance and the entire reflecting surface of the reflector appears uniform in brightness.
