Detailed Description

The present application will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1, a first prior art is a typical structure of a reflective atmosphere lamp, and includes an upper decorative plate 1a, a light guide strip 2a, a light transmission frame 3a, incident light 4a, an illuminated surface 5a, and a lower decorative plate 6a, where the light transmission frame 3a is connected and fixed to the upper decorative plate 1a by ultrasonic welding. The light of the atmosphere lamp is transmitted along the light guide strip 2a after being emitted by the lamp holder at one end, and the incident light 4a is irradiated on the illuminated surface 5a through the translucent component light-transmitting frame 3 a. Wherein, the upper plaque 1a and the lower plaque 6a are fixed in position in the vehicle.

There are two disadvantages of the existing reflective atmosphere lamp solutions. Firstly, the light of the reflective atmosphere lamp needs to be emitted through a gap hidden between the two parts of the upper decorative plate 1a and the lower decorative plate 6a, which leads to a large gap between the upper decorative plate and the lower decorative plate, and the visual effect is not beautiful. Secondly, the width of the light irradiated on the illuminated surface 5a is fixed, and no matter how the color and the brightness of the light change, the illuminated width is always unchanged, and new originality and change are lacked.

As shown in fig. 2, a second prior art is a typical structure of a direct-lighting atmosphere lamp, and the second prior art includes an inner frame 1b, a support frame 2b, a light-transmitting frame 3b, a light-guiding strip 4b, a light-transmitting gap 5b, and an outer plate 6b, where the inner frame includes an integrated vertical plate and an integrated sloping plate, and the outer plate 6b and the sloping plate are fixed in parallel with each other, so that the outer plate 6b is obliquely arranged, and an accommodating space 7b is defined between the vertical plate and the outer plate 6 b. The light of atmosphere lamp is sent back along leaded light strip 4b by the lamp holder of one end and is transmitted, directly conducts light out through translucent component printing opacity frame 3 b. Wherein, the lamp holder can adopt the matrix LED lamp to realize that RGB changes colors, flowing rhythm and light effect such as breathing.

The existing direct-lighting atmosphere lamp technical scheme has the defects that the appearance of the atmosphere lamp light guide strip 4b is directly visible without hidden feeling, the lighting position and the irradiation width of the lamp light in the vehicle are unchanged, and the technical scheme is applied in a common and uniform way and lacks of novelty.

To sum up, its main function of atmosphere lamp of present many automotive interiors still stops on basic lighting and discolours, and the leaded light strip of atmosphere lamp also is fixed mounting in the position of car, that is to say, the colour of atmosphere lamp is decided by the atmosphere lamp holder, drives atmosphere lamp leaded light strip through this light source colour of atmosphere lamp holder and shows same colour, and the width of the light that atmosphere lamp leaded light strip sent is unchangeable all the time on the face of being shone. The traditional atmosphere lamps are single in change mode, the realized functions are only basic atmosphere backing, dynamic change effects are lacked, and novel and special visual science and technology atmosphere feelings cannot be brought to users. Therefore, it is necessary to improve the installation form and control method of the conventional atmosphere lamp, to meet the user demands in different states, and to improve the comfort, technological and luxurious feeling in the vehicle.

The relative angle between the two decorative boards changes along with the music rhythm, namely the movable first decorative board 1c and/or the movable second decorative board 2c in the atmosphere lamp device dance along with the music rhythm, so that a brand new experience of dance accompaniment is provided for a user.

The releasing condition of the music mode is that the light control signal is a mode closing signal, the mode enters other modes, the position light is closed, or a user inputs a mode closing signal through the large central control screen.

Preferably, when the operation mode of the atmosphere lamp is switched to the warning mode, if the danger warning signal indicates that a dangerous situation exists, the atmosphere lamp is lighted in red, the light intensity changes along with the dangerous situation, and the decorative plates of the atmosphere lamp are opened and closed in a cycle of 1s, namely, the opening and closing frequency of the movable first decorative plate 1c and/or the movable second decorative plate 2c in the atmosphere lamp device is fast. If the danger warning signal is to remove the dangerous condition, the atmosphere lamp is extinguished, and the decorative plate of the atmosphere lamp is restored to the hidden position.

The releasing condition of the warning mode is that the light control signal is a mode closing signal, enters other modes, a position lamp is closed, or a user inputs a mode closing signal through a large central control screen.

Preferably, when the operation mode of the atmosphere lamp is switched to the emotion mode, the light control signal is obtained according to facial emotion information contained in the image signal, and after the atmosphere lamp is lightened, the light effect and the relative angle between the two decorative plates change along with the facial emotion types. The classes of facial emotions include calm, excited, sad and angry.

The face is calm and the color of the light is green, the brightness is 10cd/m2, and the movable first plaque 1c and/or the second plaque 2c are opened by half of the full opening angle and are kept still.

The facial emotion is excited, the color of the light is orange, and the brightness is 15cd/m 2. The movable first decorative plate 1c and/or the second decorative plate 2c are opened at the full opening angle first and then restored to the full opening angle of half of the opening angle and reciprocate with 2s as a cycle.

The light color is blue when the face emotion is sad, and the brightness is 5cd/m 2. The movable first plaque 1c and/or the second plaque 2c are opened at the full opening angle first and then are restored to the full opening angle of one quarter and are kept still.

The face emotion is anger, the color of the light is purple, and the brightness is 20cd/m 2. The movable first decorative plate 1c and/or the second decorative plate 2c are opened at first to enable all full-open angles and then are quickly restored to the initial state, the atmosphere lamp is turned off, after the first decorative plate stays for 2s, the first decorative plate is opened at all full-open angles again, after the first decorative plate stays for 5s, the first decorative plate is quickly restored to the initial state, the atmosphere lamp is turned off, and the process is repeated until anger is eliminated.

Referring to fig. 9, an embodiment of the present invention further discloses an atmosphere lamp control method, including:
