[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0014] See also Figure 1-4 The technical solution provided by the utility model is: an optical structure for preventing the glare of a reversing light, comprising an LED module 1 and a thick-walled member 2, wherein the light emitted by the LED module 1 is incident on the thick-walled member 2, reflected in the thick-walled member 2 and then emitted to send a signal to the vehicle behind, a concentrator 21 is arranged on the thick-walled member 2, a horizontal block 22 is arranged above the concentrator 21, a side surface of the horizontal block 22 is arranged as a light emitting surface 23, and the other side surface is arranged as an inclined surface 24, the cross section of the horizontal block 22 is a trapezoid, the concentrator 21 is located below the inclined surface 24 on the horizontal block 22, a light emitting pattern 25 is arranged on the light emitting surface 23, a plurality of arc surfaces 26 are arranged on the light emitting pattern 25, and the plurality of arc surfaces 26 are arranged on the left and right water surfaces. They are connected in sequence in the horizontal direction to form an arc surface group, and several arc surface groups are connected in sequence in the vertical direction to form a wavy light-emitting pattern 25. The two sides of the arc surface 26 are set as inclined planes 27. The light emitted by the LED module 1 enters the concentrator 21 and reaches the inclined plane 1 24 on the horizontal block 22. The light is reflected by the inclined plane 1 24 and then emitted from the light-emitting surface 23 on the horizontal block 22. When emitted, it is acted upon by the light-emitting pattern 25 on the light-emitting surface 23 to be emitted downward. Since the human eye is in a top-down state relative to the installation position of the lamp, the light irradiated obliquely upward is pressed down by the light-emitting pattern 25, thereby reducing the intensity of the light entering the human eye and preventing glare to the rear vehicle or personnel when reversing.
[0015] Specifically, the inclined plane 27 on both sides of the arc surface 26 on the light emitting pattern 25 is inclined toward the inside of the arc surface 26, and the inclination angle of the inclined plane 27 on both sides of the arc surface 26 toward the inside of the arc surface 26 is greater than the inclination angle of the arc trajectory of the arc surface 26, so that the base surface of the light emitting pattern 25 is inclined downward, so that the light emitting light is pressed downward, and the angle between the light emitting surface 23 and the vertical direction is b. This setting can prevent the light from being completely pressed downward and causing the rear vehicle or personnel to be unclear. The angle between the inclined plane 1 24 and the vertical direction is a, and a>b.
[0016] Specifically, the concentrator 21 and the inclined surface 24 on the horizontal block 22 have the same horizontal length, so that the reversing lights emit light together within the horizontal length, providing a better signal display to the rear vehicle or person.
[0017] Specifically, the angle a between the inclined plane 24 on the horizontal block 22 and the vertical direction is 45°. When the light enters from the concentrator 21 and reaches the inclined plane 24, it is reflected by the inclined plane 24 and then emitted horizontally in the horizontal block 22. The light output is stronger, providing a better signal display to the rear vehicle or personnel.
[0018] Compared with ordinary reversing lights, the utility model suppresses the light downwards without reducing the light intensity, thereby reducing the intensity of the light entering the human eye and preventing glare to the rear vehicle or personnel when reversing. Light is emitted by the LED module 1, and the light enters the concentrator 21, and is gathered by the concentrator 21. The light is emitted from the concentrator 21 to the inclined surface 1 24, and is reflected by the inclined surface 1 through the horizontal block 22 to the front to the light emitting surface 23, and then the light is suppressed and emitted by the light emitting pattern 25 with a base surface inclined downward on the light emitting surface 23. The human eye is in a top-down state relative to the installation position of the reversing light, which reduces the intensity of the light entering the human eye and prevents glare to the rear vehicle or personnel when reversing.
[0019] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
