[0001] The present invention relates to the technical field of color-changing vehicle lamps, and in particular to a color-changing vehicle lamp structure, a control system and a control method. Background Art

[0002] Car styling is becoming more and more cool, and many car owners will stick films of the same color as the car body on the lamps to achieve the effect of being integrated with the car body. However, the light transmittance of the lamp film is low, which makes it difficult for the normal light of the lamp to pass through the lamp film, making the light emitted by the lamp darker, increasing driving risks.

[0003] Chinese patent CN111322583A discloses a color-changing vehicle lamp, which adds a color-changing film structure between the LED light source board and the outer lampshade. The color-changing film changes in different colors by powering on and off, so that the LED light source board projects light sources of different colors when passing through the lampshade. However, this solution only uses the color-changing property of the color-changing film when it is powered on to form light sources of different colors, and cannot solve the problem of reducing the transparency of the lampshade so that the lampshade and the vehicle body are integrated, while ensuring that the light intensity emitted by the vehicle lamp meets the regulatory requirements. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a color-changing vehicle lamp structure, a control system and a control method to ensure the intensity of light emitted by the vehicle lamp while achieving the visual integration of the lampshade and the vehicle body.

[0005] To achieve the above-mentioned purpose, the present invention provides a color-changing vehicle lamp structure, comprising a lampshade and an LED color-adjusting lamp, the lampshade comprising an outer lampshade, an electrochromic film and an inner lampshade arranged in sequence from the outside to the inside, the electrochromic film being connected to a color-changing film power supply, the electrochromic film being used to change its own transparency when powered on, an optical structure being provided on the inner lampshade, the LED color-adjusting lamp being located on the inner side of the inner lampshade, the LED color-adjusting lamp being used to emit light of different colors, and the optical structure being used to evenly display the light emitted by the LED color-adjusting lamp on the inner lampshade.

[0006] Furthermore, at one end of the LED color-adjusting lamp close to the inner lampshade, the optical structure includes a plurality of circular arc grooves, and the farther away from the LED color-adjusting lamp, the smaller the spacing between the plurality of circular arc grooves.

[0007] Furthermore, the LED color-adjusting lamp is a three-primary-color matching lamp, and the three-primary-color matching lamp controls the displayed color by adjusting the intensity of the three primary colors.

[0008] Furthermore, it also includes a vehicle lamp shell connected to both ends of the lampshade, the vehicle lamp shell is provided with a daytime running light bracket, and the daytime running light is fixedly provided on the daytime running light bracket.

[0009] Furthermore, a headlight light source is provided in the headlight housing, and reflectors are provided on both sides of the headlight light source.

[0010] The present invention also provides a color-changing car light control system, comprising the color-changing car light structure described above, and also comprising a car light controller and a car light control panel, wherein the car light controller is respectively communicated with the color-changing film power supply, the LED color-adjusting lamp and the car light control panel, and the car light control panel is used to set the lampshade target color and the transparency threshold, and the car light controller is used to control the luminous color of the LED color-adjusting lamp according to the lampshade target color, and is also used to control the output current of the color-changing film power supply according to the transparency threshold.

[0011] Furthermore, the headlight controller is also communicatively connected to a light intensity sensor, a daytime running light and a headlight light source, and is also used to determine the light transmittance of the lampshade according to a transparency threshold and a target color of the lampshade, and to control the output power of the daytime running light or the headlight light source according to the light transmittance of the lampshade.

[0012] Furthermore, the headlight controller is also used to turn off the daytime running lights and turn on the headlight light source when the light intensity is less than the set light intensity, and turn on the daytime running lights and turn off the headlight light source when the light intensity is greater than or equal to the set light intensity.

[0013] The present invention also provides a control method based on the above-mentioned color-changing car light control system, including: obtaining the target color and transparency threshold of the lampshade, controlling the LED color-adjusting lamp to display the target color of the lampshade, controlling the output current of the color-changing film power supply according to the transparency threshold, and obtaining the lampshade transmittance according to the transparency threshold and the target color of the lampshade, and determining the output power of the daytime running light or the car light source according to the lampshade transmittance and the target light intensity after the daytime running light or the car light source passes through the lampshade.

The output power of the daytime running light or headlight light source is controlled according to the light transmittance of the lampshade and the target light intensity after the daytime running light or headlight light source passes through the lampshade, which can ensure that the light intensity emitted by the headlight meets the regulatory requirements.

DETAILED DESCRIPTION

[0021] The following specific implementations are used to further explain the technical solutions of the claims of the present invention in detail, so that those skilled in the art can more clearly understand the claims. The protection scope of the present invention is not limited to the following specific embodiments. The technical solutions of the claims of the present invention made by those skilled in the art but different from the following specific implementations are also within the protection scope of the present invention.

[0022] like Figures 1-2As shown, a color-changing vehicle lamp structure is installed as a whole between the vehicle body environment parts 700, including a lampshade 100 and an LED color-adjusting lamp 200. The lampshade 100 includes an outer lampshade 101, an electrochromic film 102 and an inner lampshade 103 arranged in sequence from the outside to the inside. The outer lampshade and the inner lampshade are both colorless and transparent. Placing the electrochromic film in the middle can prevent the electrochromic film from being damaged by the outside and prevent outsiders from contacting the electrochromic film in the power-on state. The electrochromic film 102 is connected to a color-changing film power supply. The electrochromic film changes color under different currents. The grain arrangement structure of the inner part changes, so that the electrochromic film changes from a completely regular arrangement to a disorderly arrangement. When light passes through the electrochromic film, it is scattered and refracted, so that the object inside the lampshade cannot be imaged regularly on the outside of the lampshade and becomes blurred, thereby changing the transparency of the electrochromic film. An optical structure 104 is provided on the inner lampshade 104, and the LED color-adjusting lamp 200 is located on the inner side of the inner lampshade 103. The LED color-adjusting lamp 200 is used to emit light of different colors, and the optical structure 104 is used to evenly display the light emitted by the LED color-adjusting lamp 200 on the inner lampshade 104.

[0023] The LED color-adjusting lamp 200 is a three-primary color matching lamp, including lamp cores of three primary colors of red, green and blue. The color after the three primary colors are mixed and superimposed is controlled by independently controlling the light intensity of the three primary color lamp cores, thereby controlling the color displayed by the inner lampshade.

[0024] The LED color-adjusting lamp 200 is close to the lower end of the inner lampshade 103, and the optical structure 104 includes a plurality of arc grooves, and the distance between two adjacent arc grooves is getting smaller and smaller from bottom to top along the inner lampshade 103. In this way, the light emitted by the LED color-adjusting lamp can be more evenly displayed on the inner lampshade after passing through the arc grooves.

[0025] The lamp housing 600 is also provided with a daytime running light bracket 301, and a daytime running light 300 is fixedly provided on the daytime running light bracket 301. The daytime running light is used to be turned on during normal daytime driving. A lamp light source 400 is also provided in the lamp housing 600, and reflectors 500 are provided on both sides of the lamp light source 400. The lamp light source is reflected by the reflector and then emitted through the lamp housing. The lamp light source includes a low beam and a high beam.

[0026] The present invention also provides a color-changing headlight control system, including the above-mentioned color-changing headlight structure, and also including a headlight controller 800, a headlight control panel and a light intensity sensor. The headlight controller 800 is arranged on the inner wall of the headlight housing 600, and the headlight control panel is arranged on the main console for the driver to set the target color and transparency threshold of the lampshade. The light intensity sensor is arranged on the vehicle body environment part outside the lampshade to obtain the light intensity of the external environment. The headlight controller 800 is respectively connected to the color-changing film power supply, the headlight control panel communication, the light intensity sensor, the LED color adjustment lamp 200, the daytime running light 300 and the headlight light source 400.

[0027] The car light controller 800 is used to control the light intensity of the three primary color wicks in the LED color-adjusting lamp 200 according to the target color of the lampshade, thereby controlling the display color of the inner lampshade. Since the transparency of the electrochromic film is obtained by current calibration, the car light controller is also used to control the output current of the color-changing film power supply according to the transparency threshold so that the actual transparency is equal to the transparency threshold.

[0028] The vehicle lamp controller 800 is also used to determine the light transmittance of the lampshade according to the transparency threshold and the target color of the lampshade, and to control the output power of the daytime running lamp 300 or the vehicle lamp light source 400 according to the light transmittance of the lampshade and the target light intensity after the daytime running lamp 300 or the vehicle lamp light source 400 passes through the lampshade 100. The light transmittance of the lampshade is equal to the product of the light transmittance of the electrochromic film and the light transmittance of the inner lampshade. The light transmittance of the electrochromic film can be calibrated according to the set transparency threshold, and the light transmittance of the inner lampshade can be directly calibrated according to the target color of the lampshade; the output power of the daytime running lamp 300 or the vehicle lamp light source 400 is calibrated by the output light intensity of the daytime running lamp 300 or the vehicle lamp light source 400, and the output light intensity of the daytime running lamp 300 or the vehicle lamp light source 400 is obtained by dividing the target light intensity after the daytime running lamp 300 or the vehicle lamp light source 400 passes through the lampshade 100 by the light transmittance of the lampshade.

[0029] The vehicle light controller 800 is also used to turn off the daytime running light 300 and turn on the vehicle light source 400 when the light intensity is less than the set light intensity, and turn on the daytime running light 300 and turn off the vehicle light source 400 when the light intensity is greater than or equal to the set light intensity.

[0030] The control method of the above color-changing lamp control system is as follows:

[0031] 1. Obtain the target color and transparency threshold of the lampshade, control the LED color-adjusting lamp 200 to display the target color of the lampshade, control the output current of the color-changing film power supply according to the transparency threshold, and obtain the light transmittance of the lampshade according to the transparency threshold and the target color of the lampshade, and determine the output power of the daytime running light 300 or the headlight light source 400 according to the light transmittance of the lampshade and the target light intensity after the daytime running light 300 or the headlight light source 400 passes through the lampshade 100.

[0032] The light intensity is also obtained. When the light intensity is less than the set light intensity, the daytime running light 300 is turned off and the headlight light source 400 is turned on. When the light intensity is greater than or equal to the set light intensity, the daytime running light 300 is turned on and the headlight light source 400 is turned off.

[0033] The present invention controls the intensity of the three primary colors in the LED color-adjusting lamp to make the lampshade display different colors. The driver can set the lampshade color to be consistent with the vehicle body according to preference, and changes the transparency of the electrochromic film by controlling the output current of the color-changing film power supply, so that the internal structure of the lampshade is not easy to see when observing the headlight from outside the vehicle, thereby forming a visually integrated effect of the lampshade and the vehicle body.

[0034] Since the electrochromic film can reduce transparency, the lampshade can display different colors, which both affect the overall light transmittance of the lampshade and thus affect the light intensity of the headlight after passing through the lampshade. Therefore, the light transmittance of the lampshade is obtained according to the transparency threshold and the target color of the lampshade. The output power of the daytime running light or headlight light source is controlled according to the light transmittance of the lampshade and the target light intensity of the daytime running light or headlight light source after passing through the lampshade, thereby ensuring that the light intensity emitted by the headlight meets regulatory requirements.
