[0020] It should be noted that the terms "first", "second", "third", "fourth", etc. in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0021] See also Figure 1 The present invention discloses an intelligent reading light system, including a human eye sight tracking module, a control module, a reading light module, a switch module and an information transmission module. The human eye sight tracking module is used to obtain the user's sight point location information, the control module is used to obtain the sight point location information and calculate the target irradiation position, the reading light module is used to illuminate the target irradiation position, the switch module is used to control the start and stop of the human eye sight tracking module, the control module and the reading light module, the information transmission module is used to transmit the sight point location information to the control module, and the information transmission module is also used to transmit the sight point location information to the reading light module. Specifically, the switch module in the present invention can be set as a mechanical switch, a program switch based on the central control of the car, or a voice switch based on the voice recognition function. The user can enable or stop the human eye sight tracking function of the intelligent reading light system through the switch module. For example, when the user says "tracking lighting for the main driving", the human eye sight tracking module starts to track the user's sight in the main driving position and obtains the sight point location information; the control module in the present invention can be set as the ECU of the car or a chip integrated on the ECU of the car, and the information transmission module in the present invention can be set as a corresponding communication unit of the ECU of the car. The present invention identifies the direction and position of human eyes through a human eye sight tracking module, and illuminates the direction and position of human eyes through a reading light module, thereby realizing directional follow-up lighting of a car reading light, which has a high degree of intelligence and a strong sense of technology.

[0022] Furthermore, the human eye sight tracking module in the present invention includes a visible light camera unit and an infrared camera unit, the visible light camera unit is used to obtain the user's sight point location information within the visible light band, and the infrared camera unit is used to obtain the user's sight point location information within the infrared light band. Specifically, the working principle of the human eye sight tracking module in the present invention is similar to the fatigue driving capture system or life detection system in the car. It is a module that uses a related device with a camera function to capture and track the user in real time to obtain relevant information, and is set above the central rearview mirror of the car or on the ceiling near the central rearview mirror. It is easy to understand that the visible light camera unit can capture and track the user's sight point in a scene with relatively bright light in the car, such as during the day or on a sunny day. In a preferred embodiment of the present invention, EyeLink 1000plus or a similar eye tracker device is selected as the visible light camera unit to achieve real-time capture and tracking of the user's sight direction and point; similarly, the infrared camera unit can capture and track the user's sight point in a scene with relatively dim light in the car, such as at night or in a parking lot. In a preferred embodiment of the present invention, a portable Portable Duo or a similar infrared eye tracker device is selected as the infrared camera unit, thereby achieving real-time capture and tracking of the user's sight direction and point. In addition, as mentioned above, the switch module in the present invention can be set as a voice switch based on a voice recognition function. When the user says "tracking lighting for the main driver", the visible light camera unit and the infrared camera unit are set to track the user's sight point in the main driver's seat, and when the user says "tracking lighting for the co-driver", the visible light camera unit and the infrared camera unit can also be set to track the user's sight point in the main driver's seat. In some other embodiments of the present invention, in order to track the sight point of the user in the back seat of the car, the visible light camera unit and the infrared camera unit may also be arranged on the ceiling above and near the B-pillar.

The driving device also comprises an X-direction driving gear 13, an X-direction passive gear 14, a Y-direction driving gear 15 and a Y-direction passive gear 16, the X-direction driving gear 13 and the Y-direction driving gear 15 are arranged on the lamp housing 11 and are transmission-connected to the driving device, the X-direction passive gear 14 and the Y-direction passive gear 16 are arranged on the lamp body 12 and are meshed with the X-direction driving gear 13 and the Y-direction driving gear 15 respectively, and the X-direction passive gear 14 and the Y-direction passive gear 16 can drive the lamp body 12 to rotate along the X-direction and the Y-direction respectively under the drive of the X-direction driving gear 13 and the Y-direction driving gear 15. The lamp body 12 in the present invention can realize X-direction and Y-direction rotation through the X-direction driving gear 13 and the Y-direction driving gear 15, so as to adjust the irradiation direction according to the target rotation angle to illuminate the target irradiation position. Correspondingly, the control module in the first embodiment includes a first information processing unit, which is used to process the line of sight point position information and calculate the target rotation angle of the driving device. The driving device can drive the lamp body 12 to rotate according to the target rotation angle, so that the lamp body 12 rotates to a position that can illuminate the target irradiation position. In particular, the driving motor 17 in the first embodiment is a stepping motor. After the control module calculates the target rotation angle, it is also necessary to calculate the number of revolutions required for the stepping motor, and then control the stepping motor to rotate the corresponding number of revolutions.

[0024] Furthermore, in the second embodiment of the present invention, the reading light module of the present invention includes the same lamp housing 11, lamp body 12, X-axis driving gear 13, X-axis passive gear 14, Y-axis driving gear 15 and Y-axis passive gear 16 as those in the first embodiment.

When the LED lighting unit numbered 1 is lit, the area to be illuminated numbered 1 and its surroundings are illuminated. When the target lighting group is numbered 4, numbered 7 and numbered 8, the LED lighting units numbered 4, 7 and 8 are correspondingly lit. Correspondingly, the control module in the third embodiment includes a second information processing unit, which is used to process the sight point position information and calculate the target lighting group of the LED light group. All LED light groups can be lit or extinguished according to the target lighting group, so that the LED light group illuminates the target irradiation position, and all LED lighting units can be lit or extinguished according to the target lighting group. When calculating the target lighting group, the second information processing unit in the third embodiment needs to calculate the direction vector angle of the sight point position information and the vector angle relationship of the irradiation range of all LED lighting units according to the sight point position information. For example, when it is calculated that the current sight point position of the user coincides with the irradiation range vector angle of any LED lighting unit, the LED light group is controlled to light up the LED lighting unit. In particular, the control module in the third embodiment also includes a brightness control unit, which is used to control the brightness of the LED light group according to the target lighting group, so that the corresponding LED lighting units are alternately lit or changed to light up, and the light is softer.
