As a motor vehicle, motorcycle has complex mechanical components, and the parts of the vehicle are independent and connected with each other. Understanding the parts of the motorcycle will help us to further deepen our understanding of the vehicle and help us to solve problems independently when we have problems. Today, our motorcycle class will talk about the car's headlights and explore the mystery of the vehicle's headlights. We all know that different models have different headlight shapes, but the ultimate goal is to use for lighting. So, does the shape of motorcycle headlight affect the brightness?

Motorcycle headlamp is generally composed of bulb, reflector, lens, etc. if LED bulb composed of multiple small light sources is used in multi reflection headlamp, a new lighting design will appear. The traditional motorcycle headlamp is generally composed of halogen lamp, that is, the lamp with yellow lighting. However, the halogen lamp only has one bulb, which can not fully meet the performance requirements of the headlamp. The headlamp needs to use the reflector and lens to irradiate the light emitted by the light source to the appropriate direction and range. Therefore, the headlamp is not only a light source, but also depends on the quality of light distribution.

Nowadays, with the progress of science and technology and industry, the development of motorcycles has been very advanced. Most motorcycles bid farewell to halogen lamps and adopt LED lights with more obvious lighting. We can find that there is almost no cutting multi reflection headlamp in the headlamp lens. In this way, the reflector composed of multiple small mirrors is used to control the light distribution while reflecting. Halogen lamp and high pressure gas discharge lamp can be used in this way. Its biggest advantage is that the brightness is greatly improved by careful calculation of reflector and uncut lens. Moreover, the shape design of lamp is larger and personalized lamp can be realized without the restriction of lens shape.

Now in the motorcycle circle, many car friends who advocate individuality will refit their cars when they buy their cars. Many of them choose to add lens or replace the whole headlight. In order to show its uniqueness, some motorcycles often use projection bulb. This method adopts the principle of projector and uses lens to control light distribution. The biggest advantage is that the volume can be reduced and the light diffusion can be reduced. However, there is a disadvantage that the light scattering is less and the feeling is dim.

At present, the headlight of locomotive is equipped with low beam lamp and high beam lamp, which can be used alternately according to driving conditions. Generally speaking, the high beam is used when there is no vehicle at night, and the low beam lamp is used for meeting. In theory, the effective illumination distance of the low beam lamp is 40 meters, but in fact, the distance you can see with your helmet is not so much. Therefore, it is better to use high beam light at night when there is no car to see more clearly and farther.
