Problems solved by technology

[0007] That is, only by arranging a cylindrical lens on the front side of a plurality of light emitting elements, the lateral width of the light distribution pattern becomes wider, and as a result, the front side of the vehicle lamp cannot be brightly illuminated.
That is, it is impossible to form a so-called dot-like light distribution pattern where light is condensed.
In addition, even if the size of the cylindrical lens in the left and right direction is increased in order to effectively utilize the light radiated to the front from the plurality of light emitting elements and diffused in the left and right direction, the characteristics of the cylindrical lens cannot form a converging light. light distribution pattern
On the other hand, if a lens other than a cylindrical lens is used in order to form a so-called point-like light distribution pattern that is condensed, and to effectively utilize the light that is diffused in the left and right directions among the lights radiated to the front from a plurality of light emitting elements, Then the size of the left and right directions of the vehicle lamps will become larger

Abstract

Provided is a vehicle lamp to reduce the horizontal size of a cylindrical lens and illuminate the front of a vehicular lighting fixture brightly. The vehicular lighting fixture comprises a plurality of LEDs (1A, 1B, 1C, ..., 1M) arranged on a straight line (L) extending in a horizontal direction, and a cylindrical lens (2) for condensing light emitted forward from the LEDs (1A, 1B, 1C, ..., 1M) in the vertical direction of the vehicular lighting fixture. In this vehicular lighting fixture, condensing lens sections (3A, 3B, 3C, ..., 3M) that exhibit a higher degree of light condensing in the horizontal direction than in the vertical direction are provided between the cylindrical lens (2) and the respective LEDs (1A, 1B, 1C, ..., 1M).

Description

technical field [0001] The present invention relates to a lamp for vehicles, which has a plurality of light-emitting elements arranged on a straight line extending in the left-right direction, and is provided with a cylindrical lens that directs the light radiated from the plurality of light-emitting elements to the front side up and down. Focusing light in a direction, in particular, relates to a vehicle lamp capable of reducing the lateral dimension of a cylindrical lens and brightly illuminating the front side of the vehicle lamp. [0002] More specifically, the present invention relates to a vehicle lamp that irradiates arbitrary light such as infrared rays or visible light to the front side of the vehicle lamp. Background technique [0003] Conventionally, there is known a vehicle lamp in which a plurality of light emitting elements are arranged in a straight line and a cylindrical lens is provided. As examples of such vehicle lamps, there are, for example, those descr...
