[0002] Car headlights are one of the most important components of a car, providing illumination at night or in inclement weather. The distance and range of headlight illumination reflect its performance. In addition to high and low beams, headlights also have daytime running lights (DRLs). DRLs serve to indicate width and provide warnings. Their illumination distance and range are limited, but their main purpose is to improve visibility, show the width of the vehicle, and make it easier for other drivers to identify. DRLs have a wide illumination range and high illumination intensity, which can assist high and low beams and improve the overall performance of the headlights. To improve the lighting performance of DRLs, a type of car headlight that can illuminate over long distances has been developed. Utility Model Content

[0018] A long-distance illumination automotive headlight includes: a rear housing and a front lamp cover; the rear housing has an inner lamp housing 1, on which a high / low beam assembly and a turn signal assembly are mounted. The inner lamp housing 1 has mounting holes for the high / low beam assembly and recessed holes for the turn signal cover 9 of the turn signal assembly. The high / low beam assembly has a high / low beam lens assembly and a daytime running light assembly 2. The daytime running light assembly 2 is annular in shape and is fixed at the mounting holes of the high / low beam assembly. The lens 3 of the high / low beam lens assembly is located at the center hole of the daytime running light assembly 2. The daytime running light assembly 2 has an annular housing 4, a lamp panel, and a daytime running light cover 5. The lamp panel is an LED lamp panel and is annularly fixed in the lamp groove 6 of the annular housing 4. The daytime running light cover 5 is fixed to the annular housing 4 by screws.

[0019] The daytime running light cover 5 has a raised first light-emitting cover 7 and a second light-emitting cover 8. The first light-emitting cover 7 and the second light-emitting cover 8 are arranged in an alternating ring array. The light-emitting surface of the first light-emitting cover 7 is composed of an array of multiple unit surfaces 10. Each unit surface 10 is composed of three intersecting surfaces. The unit surface 10 can scatter the light source in multiple directions and expand the illumination range. The light-emitting surface of the second light-emitting cover 8 is a plane 11, which can concentrate the light source and increase the scattering intensity.

[0020] There are ten first light-emitting covers 7 and ten second light-emitting covers 8. The first light-emitting covers 7 and the second light-emitting covers 8 are arranged close to each other and alternately, so that the resulting diffused light source is more recognizable.

[0021] The second light cover 8 extends into the inner side of the daytime running light cover 5 in a raised shape. The inner end of the second light cover 8 protrudes from the inner end of the adjacent first light cover 7 on the left and right, and the outer end of the first light cover 7 protrudes from the outer end of the second light cover 8.

[0022] The first light-emitting cover 7 has two intersecting light-emitting surfaces. The dividing line between the two surfaces is an arc drawn with the center of the daytime running light cover as the center. The two surfaces of the first light-emitting cover 7 are inclined inward and outward respectively with the dividing line as the high point. The inclination of the two surfaces expands the illumination range. One end of the second light-emitting cover 8 extends outward to the dividing line between the two surfaces of the first light-emitting cover 7.

[0023] This utility model designs the daytime running light in a ring shape, and sets a first light-emitting cover 7 and a second light-emitting cover 8 on the daytime running light cover 5. The light-emitting surface of the first light-emitting cover 7 can radiate light both outward and inward, expanding the illumination range and intensity. The setting of the second light-emitting cover 8 further improves the radiating point of the light source and concentrates the light source to improve the illumination intensity, and radiates the light source to form a ring matrix shape, thereby improving the visibility of the daytime running light.
