Headlights for two-wheeled motorcycles

Abstract

In the headlamp in which the low beam and the high beam of the LED light source are integrated, the light distribution characteristic necessary for the headlamp can be obtained without making the luminous impression of the high beam too prominent. The reflector (341) for high beam is arranged below the LED light source (46) for high beam, and reflects light from the LED light source (46) for high beam toward the front of the vehicle. The reflectors (342, 343) for low beams are arranged below the LED light sources (45) for low beams, and reflect light from the LED light sources (45) for low beams toward the front of the vehicle. The LED light sources (45) for low beams are located on the left and right sides of the LED light sources (46) for high beams, and are arranged in front of the LED light sources (46) for high beams. The reflector for high beam (341) is longer in the front-rear direction than the reflector for low beam (342, 343), and the reflector for low beam (342, 343) and the reflector for high beam (341) compared to the front.

Description

technical field [0001] The present invention relates to a headlight device for a motorcycle, and more particularly to a headlight device for a motorcycle suitable for emphasizing the light emission impression of the low beam with respect to the low beam and the high beam housed in an integral housing. Background technique [0002] Conventionally, in a headlight device for a two-wheeled motorcycle in which a low beam and a high beam are integrally accommodated, a configuration has been disclosed in which a bulb light is arranged as a high beam in the center of the vehicle width direction, Project lights are arranged as low beams on the left and right of the high beams. In addition, hereinafter, "low beam light" and "high beam light" are simply described as "low beam" and "high beam", respectively.

AI Technical Summary

Problems solved by technology

Then it can be considered that, in the headlight device in which the low beam and the high beam are housed integrally, it is necessary to make the reflector for the high beam shorter than the reflector for the low beam in order to ensure the light distribution characteristics of the high beam. longer, so the shape of the high beam is noticeable and the luminous impression of the low beam becomes unobtrusive
