Description

Technical Field

[0001] The present invention relates to the technical field of intelligent automobile lamps, and more specifically, to a color projection lamp module. Background Art

[0002] At present, cars have become the main means of transportation and means of travel for ordinary people. Car lights are generally used for lighting, such as high beam lighting and low beam lighting. The wave of automotive intelligence and the continuous iteration of underlying light source technology have promoted the evolution of car lights from the previous single lighting to the direction of intelligence and emotionality. Tens of thousands or millions of pixel projection headlights that can realize intelligent lighting, projection interaction and more possible shapes are becoming a new trend.

[0003] Currently, million-pixel projection generally adopts a solution based on Texas Instruments' DMD chip. The image is projected and output by irradiating the DMD chip with light, adjusting the micromirror switch on the DMD chip, and cooperating with the projection lens. The color of the light source is white light, so the final output of the projection headlight is also white light.

[0004] The invention patent with announcement number CN220981088U discloses a multi-pattern projection lamp, including: a multi-pattern projection lamp, including: a shell, a light-transmitting portion is provided at the upper end of the shell; a circuit board is arranged in the shell, a plurality of light-emitting elements are arranged on the circuit board, and the plurality of light-emitting elements are distributed below the light-transmitting portion and distributed on the circuit board at circumferential intervals; a plurality of optical modules are arranged in the shell and respectively located between the plurality of light-emitting elements and the light-transmitting portion, the optical module includes a shell and a focusing lens group, a film and an imaging lens group arranged in sequence from bottom to top in the shell: the circuit board is used to individually control the on and off state of each light-emitting element, the focusing lens group is used to focus and deflect the light emitted by the corresponding light-emitting element, so that the light emitted by different light-emitting elements is imaged at the same position of the imaging surface after being emitted through the corresponding optical module, without splicing to form the required light type; and when forming projections of different patterns, it is only necessary to control a single light-emitting element to light up.

[0005] However, the above technical solution only supports monochromatic light emitted by the light-emitting element, which cannot meet the demand for color images. In view of this, the present invention proposes a color projection light module so that the final output of the projection headlight can also present color light. Summary of the invention

[0006] In view of this, in order to solve the above problems, the present invention proposes a color projection light module, including a lens barrel 1, a light source 3, a color wheel 4 and a lens group 2, characterized in that: the interior of the lens barrel 1 is a hollow structure, the lens barrel 1 contains a lens group 2, the lens group 2 is composed of a plurality of lenses, the light inlet of the lens barrel 1 is connected to a light board, the light board is provided with a light source 3, the light source 3 can map a screen image through the light board and the lens group 2, the color wheel 4 is arranged between the lens group 2 and the light source 3 or between adjacent lenses in the lens group 2, a motor 5 is arranged at the center point of the color wheel 4, the motor 5 rotates at a certain frequency, thereby driving the color wheel 4 to rotate, the center point of the color wheel 4 is located near the edge of the light source 3, and the top of the motor 5 is arranged near the edge of the light source 3, when the light color of the light source 3 changes, the color wheel 4 can be replaced to change to a light-transmitting area or a transmission area.

[0007] In some embodiments, the color wheel 4 is circular or polygonal in shape, and a plurality of color partitions are arranged on the color wheel 4. Adjacent color partitions are of the same or different colors, and the plurality of color partitions are of at least two different colors.

[0008] Furthermore, the image projected by the light source 3 through the light board and / or the lens group 2 does not exceed the area where each color partition is located.

[0009] In some embodiments, when the light color emitted by the light source 3 is consistent with the desired picture image color, a color partition on the color wheel 4 can be made into a transparent light-transmitting area, which is a light-transmitting sheet or a non-color wheel 4 notch area, and the picture image stays in this area.

[0010] Furthermore, when the light color emitted by the light source 3 is white light, the color wheel 4 is provided with a plurality of non-transparent light-transmitting areas and a transparent light-transmitting area, wherein the transparent light-transmitting area is a light-transmitting sheet or a non-notch area of ​​the color wheel 4, and each color partition can adopt a light-transmitting sheet of a certain color.

[0012] Furthermore, when the light color emitted by the light source 3 is white light, and the light color of the picture image is required to be colored, the color wheel 4 can be divided into four color partitions, namely: a transparent light-transmitting area, a blue light-transmitting area, a green light-transmitting area and a red light-transmitting area. The motor 5 rotates at a certain frequency to separate different monochromatic lights on a specified light path, and finally synthesizes them in time sequence to project a colored picture image.

[0013] Furthermore, when the light color emitted by the light source 3 is blue light, and the required image light color is color, the color wheel 4 can be divided into four color zones, namely: a transparent light transmission zone, a yellow light transmission zone, a green light transmission zone and a red light transmission zone, and each color transmission zone is coated with a fluorescent coating. The motor 5 rotates at a certain frequency to separate different monochromatic lights on a specified light path, and finally synthesizes them in time sequence to project a color image.

[0014] Furthermore, when the light color emitted by the light source 3 is blue light, and the image light color is required to be colored, the color wheel 4 can be divided into three color partitions, namely: a transparent transmission area, a green transmission area and a red transmission area, and each color transmission area is coated with a fluorescent coating.
