[0042] See also Figure 1 As shown, the present application provides a train passenger compartment lighting device that is easy to maintain, which is arranged in the train passenger compartment for illuminating the train passenger compartment. The train passenger compartment lighting device that is easy to maintain includes a light-emitting device, a guide device and a light-guiding device.

[0043] The light-emitting devices are arranged at intervals at one end of the train passenger compartment, the light-emitting devices are used to emit illumination light, the guiding device is arranged at the output end of the light-emitting device, and is used to change the illumination light path of the light-emitting device, the light-guiding device is arranged at the top of the train passenger compartment, the light-guiding device is used to receive the illumination light and emit the illumination light into the train passenger compartment, and the light source is provided by the light-emitting device. Conventional train passenger compartment lighting devices arrange the light sources at the top of the train passenger compartment, and when inspection and maintenance are required, staff need to climb up to maintain them. The light-emitting device in the easy-to-maintain train passenger compartment lighting device provided in the present application is arranged on one side of the train passenger compartment, which is convenient for staff to maintain, and the path of the light path of the light-emitting device is changed by the guiding device, so that the illumination light is delivered to the light-guiding device, and the illumination light is diffused into the train passenger compartment through the light-guiding device.

[0044] The light-emitting device includes an LED lamp 100 and a reflective cup 110. The LED lamp 100 is arranged at one end of the train passenger compartment. The LED lamp 100 is used to emit irradiation light. The reflective cup 110 is set as a cup-shaped structure with two ends open. The reflective cup 110 includes an input end and an output end. The input end of the reflective cup 110 is connected to one side of the LED lamp 100. The inner wall of the reflective cup 110 can reflect the irradiation light. The LED lamp 100 is used to emit irradiation light. The irradiation light is continuously reflected on the inner wall of the reflective cup 110 and finally gathered into a light beam and emitted from the output end of the reflective cup 110.

[0045] The light-emitting device includes a lens 120, which is connected to the output end of the reflective cup 110. The lens 120 includes a connecting portion 121 and a focusing portion 122. The connecting portion 121 is configured as a circular plate structure, and the focusing portion 122 is configured as a hemispherical structure. Through the configuration of the lens 120, the illumination light of the light-emitting device enters the lens 120 through the connecting portion 121, and is then further focused by the focusing portion 122.

[0046] The guiding device also includes a first reflector 130, which is arranged on one side of the light-emitting device. The first reflector 130 has a 45-degree angle with the optical path of the illumination light. Through the setting of the first reflector 130, the illumination light of the light-emitting device is changed in direction for the first time, so that the illumination light is directed toward the top of the train passenger compartment.

[0047] The guiding device also includes a second reflector 140, which is arranged at an interval on one side of the first reflector. The second reflector 140 is arranged parallel to the first reflector, and the reflecting surface of the second reflector 140 is arranged opposite to the reflecting surface of the first reflector. Through the setting of the second reflector 140, the irradiation light reflected from the first reflector is reflected for a second time, so that the irradiation light is irradiated toward the light guide device.

[0048] The guiding device also includes a first partition 150, which is arranged between the light-emitting device and the first reflector. The first partition 150 is arranged as a straight plate structure.

By arranging the second partition 160 between the light-emitting device and the second reflector 140, the diffusion leakage of the illumination light is reduced, thereby improving the lighting effect.

[0050] The guiding device also includes a third partition 170, which is arranged on the side of the first reflector away from the first partition 150. The third partition 170 is arranged as a straight plate structure. Through the arrangement of the third partition 170, it is used to cooperate with the first partition 150 and the second partition 160 to enclose the light-emitting device, the light-guiding device, the first reflector and the second reflector 140 to prevent the diffusion and leakage of the illuminated light and improve the illumination effect.

[0051] The light guide device includes a light guide plate 180, which is configured as a translucent straight plate structure. The surface of the light guide plate 180 close to the train passenger compartment is configured as a frosted structure. Through the configuration of the light guide plate 180, after the irradiation light enters the light guide plate 180, it is irradiated into the train passenger compartment from the side close to the train passenger compartment. Since the light guide plate 180 close to the train passenger compartment is configured as a frosted structure, the irradiation light is diffusely reflected, so that the irradiation light is evenly irradiated in the train passenger compartment.

[0052] In summary, the train passenger compartment lighting device provided in this application that is easy to maintain has a simple overall structure, and the light-emitting device is arranged on one side of the train passenger compartment. Workers do not need to climb high for inspection, which improves the convenience of inspection and maintenance.
