Corresponding pointing light distribution type led lights for ground vehicles area

Abstract

The invention discloses an area-corresponding pointing light-distribution type LED lamp of a ground transportation tool. The LED lamp comprises an LED light source, a light distributor, a light reflector and a light shade, wherein the light distributor is arranged on the path of some light from the LED light source, some light passes through the light distributor and is refracted outside to provide lighting of a main lighting area, the light distributor directly forms a clear cut-off line between the main lighting area and a right dark area and between the main lighting area and a side lighting area; the light reflector is arranged on the periphery of the LED light source and the light distributor to reflect some light from the LED light source to the side lighting area, a side high lighting area and other areas in need of uniform lighting supplement and connection lighting respectively; the light reflector directly forms a broken line which is a 45-degree upward inclined line relative to the horizontal line and turns into a horizontal direction line when the horizontal vertical distance is 25 cm or after the reflection surface rotates, a 15-degree upward inclined line relative to the horizontal line is formed; and the light shade shades the fifth part of light except from the light distributor and the light reflector wrap corners, and light leakage is avoided.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with area-corresponding pointing light distribution on a ground vehicle. Background technique [0002] Headlights, also called headlights, are installed on both sides of the head of vehicles such as automobiles for nighttime lighting. Because the lighting effect of the headlight directly affects the operation and traffic safety of driving at night, the traffic management departments of various countries in the world have stipulated its lighting standards in the form of laws. With the continuous development of technology, the incandescent vacuum lamps of the past have been eliminated successively. Now the headlights of automobiles are mainly halogen lamps and xenon lamps. [0003] The headlights of vehicles, such as car headlights, have their own unique light distribution structure, which can also be divided into high beam and low beam according to the type of light. For example, the l...

Problems solved by technology

These two solutions have corresponding defects. The former needs to install side lights, and needs to sample the steering wheel signal, which increases the complexity of the system.

The latter uses the traditional mechanical principle, there are mechanical failures, and the response time is slow
