Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories. Background Art

[0002] With the continuous development of the automotive industry, consumers' demands for in-car entertainment are becoming increasingly demanding. Ambient lighting has become an indispensable part of automobiles. While being both practical and aesthetically pleasing, it also enhances the functionality of car interiors. However, current ambient lighting on the market lacks interactive features, cannot be linked to in-car entertainment, and features a single color scheme, failing to fully meet consumers' individual needs. Utility Model Content

[0003] In view of the above technical problems, the utility model provides an atmosphere lamp control system and an atmosphere lamp.

[0004] An atmosphere light control system, such as Figure 1 As shown, it includes a main control module, a multi-channel LED module, an audio acquisition module and a power module;

[0005] The LIN control unit of the main control module is connected to the LIN communication interface for accessing the vehicle body communication network, the SPI control unit is connected to the multi-channel LED module, and the ADC control unit is connected to the audio acquisition module. The audio acquisition module collects the vehicle body audio and outputs the signal to the ADC control unit. After receiving the audio data, the main control module performs FFT calculation and feeds the result back to the multi-channel LED module to realize linkage with the in-vehicle entertainment. The power supply module is used to supply power to the main control module and the multi-channel LED module.

[0006] An ambient light, such as Figure 2-3 As shown, light board brackets 2 are installed on both sides of the shell 1, and an RGB light board 3 with multiple LEDs is installed on the inner surface of the light board bracket 2. Multiple light guides 4 pass through the positioning holes on both sides of the shell 1 and correspond to the LEDs on the RGB light board 3 respectively. A mask 5 covers the front surface of the shell 1, and the inner surface of the mask 5 is a laser engraved pattern. The shell 1 also includes a circuit board integrated with the atmosphere light control system.

[0007] Technical effect:

[0008] The utility model solves the technical problem that the existing atmosphere lights cannot be linked with in-vehicle entertainment through an atmosphere light control system. It is connected to the vehicle body control system through the LIN communication interface. The audio acquisition module collects the vehicle body audio and outputs the signal to the ADC control unit. The main control module performs FFT calculation after receiving the audio data and feeds the result back to the multi-channel LED module, thereby controlling the light color and brightness of the left and right LEDs to achieve color adjustment, light intensity and other effects. At the same time, the pattern and color of the inner surface of the mask can be customized according to customer needs, which increases the functionality of the atmosphere light. The utility model has a simple design structure, is easy to install, and is not restricted in position. The overall thickness of the atmosphere light is ultra-thin. Compared with the existing 10-15mm thick atmosphere lights, the thickness of the entire lamp of the utility model is 7-8mm. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is the overall structural block diagram of the atmosphere light control system of this utility model.

[0010] Figure 2 This is a schematic diagram of the structure of the atmosphere lamp of the present utility model.

[0011] Figure 3 This is a schematic diagram of the decomposition of the atmosphere light of the present invention. DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and technical effect of the present invention more clear, the specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, it should be noted that for ease of description, the accompanying drawings only show parts relevant to the present invention and not all of the contents.

[0013] The main control module uses YTM32B1LE05H0VLFT as the main control chip, and the M0+ core MCU main frequency can reach 48M; the audio acquisition module uses MAX4466 microphone amplifier for audio acquisition.

[0014] The power supply module consists of two parts. One part is provided by TPS5430 DCDC step-down to provide 5V power, which is mainly used to power multiple LED modules. The other part is provided by ASM1117 to provide 5V power, which is mainly used to power the main control module.

[0015] The inner surface of the ambient light housing is aluminum-plated, and screw holes are distributed around it, and it is assembled with the car body by screws.

[0016] Five independent light guides pass through the middle of the shell. The light guides are evenly distributed with light guide rulers. LED side lighting is used, and the side of the light guide is used as the light input end. The light enters the light guide, making the light distribution even and without bright spots. It can be added according to actual needs and is not limited to 5 independent light guides.

[0017] The LED is OSRAM's KRTBID2LM31.31 SmartLED, which uses serial communication to minimize the number of inter-board connections and is extremely easy to expand. It also has internal RGB calibration data to make the displayed colors more realistic.
