Providing the driver with the effect of illuminating the road to ensure safe driving when the driver is dim, the line of sight is unknown or driving at night.

Among them, in the case of locomotive headlights, when the regulations are verified, when the near-light car light is illuminated on a vertical screen 10 meters away, the near-light type is a horizontal straight line cut-off line, which is divided into bright The area and the dark area, and the near-light beam is only slightly semi-circular when projected on the ground. Please refer to the M623226 "Structure of LED locomotive headlights" announced on October 11, 102, which mainly includes: a lamp housing. Defining an opening; a reflector lamp cup fixed at the opening; a heat dissipation module housed in the lamp housing defines a base portion through which the reflector lamp cup is disposed; at least one is disposed at a front end of the base portion a first light-emitting element; at least one second light-emitting element disposed at one side of the base and horizontally disposed; and at least one third light-emitting element disposed at the other side of the base and horizontally disposed. Wherein the reflector lamp cup is located at one side of the base to define a high-beam reflection portion that provides a light source with a refraction angle, and the reflector lamp cup is located at the other side of the base portion to define a near-light reflection that provides a light source with a refractive angle closer to the base. unit.

However, the above-mentioned "structure of the LED locomotive headlight" allows the second illuminating element to be projected by the near-light reflecting portion to achieve the intended effect of producing a downward refracting near-light effect, but it is also found in its actual implementation. The near-light type projected by the near-light reflection portion is only slightly semi-circular when projected onto the ground, and is linear in the front end of the near-light type [refer to the light pattern diagram of the near-light illumination area in the fifth figure) It is not possible to have a large range of illumination on the front side of the locomotive knight, which limits the range of illumination that can be illuminated by the near-light type, so that there is still room for improvement in the overall structural design.

In the light of this, the creators have made a lot of research and development and practical production experience in the relevant industries for many years, and researched and improved the existing structures and defects, and provided a projection locomotive headlight with two sides extending light distribution, with a view to Those who achieve better practical value.

The main purpose of the present invention is to provide a projection locomotive headlight with a light distribution on both sides, which mainly enables the light emitted by the illuminating source to utilize the light incident surface of the projection optical lens and the arc on both sides of the light incident surface. Forming into the light flap for projection, and the projected overlapping near-light illumination region extends forwardly on both sides to form an illumination extension section, so that the formation of the illumination extension section can have a wider illumination area, This allows the locomotive knight to obtain better lighting effects, which can increase the safety of driving, and it has more practical functions in its overall implementation.

The main purpose and effect of the projection locomotive headlights with extended light distribution on both sides are achieved by the following specific technical means:
