[0025] The features and performance of the light guide structure of the luminous LOGO lamp for vehicles of the present application are further described in detail below in conjunction with the embodiments.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, the present application provides a light guide structure of a vehicle luminous LOGO lamp, which includes a detachably connected outer lens 100 and a lamp housing 110; the outer lens 100 includes an opaque area 101 and a translucent LOGO area 102; the outer lens 100 and the lamp housing 110 enclose a receiving cavity 120, a PCB board 130 and a light guide plate 140 located between the outer lens 100 and the PCB board 130 are arranged in the receiving cavity 120, one side of the light guide plate 140 is bent toward the PCB board 130 to form a light input end 150, and one side of the PCB board 130 is connected to a row of 10 LED lamps 160 arranged at intervals and arranged opposite to the light input end 150. The side of the light guide plate 140 away from the outer lens 100 is recessed to form a conical reflective point 170 arranged in an array. The outer lens 100 and the light guide plate 140 are arranged in parallel. The outer lens 100 and the light guide plate 140 are both made of transparent polycarbonate material. The outer lens 100 is shadingly treated with paint to form a light-proof area 101, and a light-transmitting LOGO area 102 is formed in the uncoated area. The lamp housing 110 is made of an opaque plastic material. In this embodiment, the lamp housing 110 is made of polyethylene material.

[0028] The vehicle luminous LOGO lamp light guide structure provided in the embodiment of the present application is provided with a PCB board 130 and a light guide plate 140 located between the outer lens 100 and the PCB board 130 in the accommodating cavity 120 formed by enclosing between the outer lens 100 and the lamp housing 110. One side of the light guide plate 140 is bent toward the PCB board 130 to form a light input end 150, and a row of LED lamps 160 arranged opposite to the light input end 150 is provided on the PCB board 130. The light emitted by the LED lamp 160 can enter the light guide plate 140 through the light input end 150 and then diverge and evenly emit through the light-transmitting LOGO area 102 of the outer lens 100, thereby ensuring that fewer LED lamps 160 can evenly pass through the light guide plate 140 to achieve the lighting effect, avoiding the need to evenly arrange LED lamps on the PCB board 130 in existing vehicles, and effectively reducing costs.

[0029] In addition, the side of the light guide plate 140 away from the outer lens 100 is recessed to form conical reflective points 170 arranged in an array. When the light emitted by the LED lamp 160 enters the light guide plate 140 through the light incident end 150 and then diverges, the conical reflective points 170 can be used to further reflect the light entering the light guide plate 140, thereby ensuring that the light guide plate 140 emits the light evenly in all directions, thereby achieving even lighting of the LOGO light in a smaller car light space, achieving a good lighting effect while saving costs.

[0030] In other optional embodiments, the number of LED lamps 160 arranged on the PCB board 130 and opposite to the light incident end 150 can be adjusted according to actual conditions, and can be less than 10 or more than 10.

[0031] Example 2

[0032] like Figure 3 As shown, the embodiment of the present application provides a light-guiding structure for a vehicle luminous LOGO lamp, which is substantially the same as the structure of the light-guiding structure for a vehicle luminous LOGO lamp provided in Example 1, with the difference that, in the present embodiment, both sides of the light guide plate 140 are bent toward the PCB board 130 to form a light input end 150, and both sides of the PCB board 130 are respectively connected to a row of spaced-apart LED lamps 160, and the two rows of LED lamps 160 are respectively arranged opposite to the two light input ends 150.

[0033] In the embodiment of the present application, a light input end 150 is formed by bending the two sides of the light guide plate 140 toward the PCB board 130, and a row of LED lamps 160 are respectively connected to the two sides of the PCB board 130, which are arranged at intervals and opposite to the corresponding light input ends 150. This ensures that the light emitted by the LED lamp 160 enters the light guide plate 140 through the light input end 150, and then diverges and is evenly emitted through the light-transmitting LOGO area 102 of the outer lens 100.

[0034] In other optional embodiments, three, four or multiple sides of the light guide plate 140 may be bent toward the PCB board 130 to form a light input end 150, and multiple LED lights 160 aimed at each light input end 150 may be arranged on the PCB board 130.

[0035] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
