Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0027] see figure 1 , figure 2 and image 3 As shown, a light distribution structure of an automobile headlight is composed of a sunshade 1, an LED light source 3, an LED lens 4, a reflector 2 and a tongue-shaped reflector 5, and the tongue-shaped reflector 5 is arranged at the lower part of the sunshade 1, Figure 11 and Figure 12 The shown LED lens 4 covers the light-emitting surface of the LED light source 3 and is installed in the reflector 2 to form a whole. The whole is installed in the shading cover 1. For the structure of the shading cover 1, refer to Figure 4 , Figure 5 and Figure 6 shown. The opening of the reflector 2 is inclined downward by 40°, and the tongue-shaped reflector 5 is made of reflective material. For its structure, see Figure 7 , Figure 8 , Figure 9 and Figure 10 shown. This light distribution structure can form ...

The invention discloses an automobile headlamp grading structure and a light-emitting diode (LED) automobile headlamp using the structure. The automobile headlamp grading structure comprises a lens hood, an LED light source and an LED lens, and the automobile headlamp grading structure is characterized by further comprising a reflector and a tongue-shaped reflector, the tongue-shaped reflector is arranged on the lower portion of the lens hood, the LED lens is covered on a lighting surface of the LED light source and installed in the reflector, a whole is formed, and the whole is installed in the lens hood. The automobile headlamp grading structure forms a duck tongue-shaped distribution curve flux, irradiating light intensity of upwards horizontal light is limited in a certain scope when two automobiles meets due to the grading structure, glare problems caused by automobile lamps at night can be solved, and the light can be sufficiently used due to reflection effects of the tongue-shaped reflector. The automobile headlamp grading structure can be applicable to various automobile headlamps.
Description
technical field [0001] The invention relates to a light distribution structure of an automobile headlight and an LED automobile headlight designed using the structure, so as to effectively control the irradiation height of the light of the automobile headlight during normal driving, reduce light pollution, and prevent the light from dazzling drivers, passengers or pedestrians on the opposite side The utility model belongs to the field of lighting appliances or auto parts. Background technique [0002] The structure design of existing automobile headlights utilizes the principle of light reflection. It is usually composed of a light source and a parabolic reflector cavity. It is divided into two types: low beam and high beam. When driving normally at night, especially on the highway at night, the high beam is used. Lighting, with a high lighting angle, is likely to cause glare to drivers or pedestrians facing the same direction ahead, while the low beam lighting angle is too ...
