Problems solved by technology

[0005] However, due to the positional relationship between the reflector for the condensing area and the reflector for the diffusion area, a part of the light reflected by the reflector for the diffusion area is blocked by the reflector for the condensing area, and the irradiation area in front of the vehicle may be blocked. Reduced visibility of the side of the

Embodiment Construction

[0022] Hereinafter, a vehicle lamp according to an embodiment of the present invention will be described in detail with reference to the drawings. In addition, in this specification, when terms indicating directions such as "upper", "lower", "front", "rear", "left", "right", "inside" and "outside" are used, they are Indicates the direction in the posture when the vehicle lamp is mounted on the vehicle.

[0023] figure 1 It is a schematic horizontal cross-sectional view of the vehicle lamp 10 according to the embodiment of the present invention. in addition, figure 2 yes figure 1 AA cross-sectional view of the illustrated vehicle lamp 10 . figure 1 The illustrated vehicle lamp 10 is a headlamp in which one lamp is disposed on each of the left and right sides of the front of the vehicle. Since its structure is substantially the same on the left and right, the structure of the vehicle lamp disposed on the left side of the vehicle is represented. illustrate.

Abstract

A vehicle lamp 10 includes a first parabolic high-beam condensing reflector 16b, a second parabolic high-beam condensing reflector 17c and a parabolic high-beam diffusing reflector 16a. The first and second parabolic high-beam condensing reflectors 16b, 16c forms a high-beam condensed light distribution pattern by reflecting light emitted from light sources 18b, 18c. The high-beam diffusing reflector 16a forms a high-beam diffused light distribution pattern by reflecting light emitted from a light source 18a. A part 21 of a reflection surface of the high-beam diffusing reflector 16a is located in front of front end portions of the first and second parabolic condensing reflectors 16b, 16c.

Description

technical field [0001] The present invention relates to a vehicular lamp, and particularly relates to a vehicular lamp using a light-emitting element such as an LED and a parabolic reflector. Background technique [0002] Conventionally, a vehicular lamp is known that includes a plurality of LEDs and a plurality of reflectors that reflect light from the LEDs (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2011-81975 [0004] Usually, when a predetermined light distribution pattern is formed using a plurality of reflectors, some of the reflectors are formed to irradiate light to a light-condensing area in a light distribution pattern called a hot spot, and other reflectors are formed to irradiate light to a hot spot. The surrounding diffused area shines light. [0005] However, due to the positional relationship between the reflector for the condensing area and the reflector for the diffusion area, a part of the light ref...
