Besides the telecommunication connection between the width indicating lamp and the controller, the light combination assembly and the automobile instrument panel are connected through the bus, so that the effective work between the automobile instrument panel and the light combination assembly can be ensured.
As a further aspect of the present invention: the dipped headlight D2 is connected with the switch K2 and then connected with the width indicator in parallel, the high beam D3 is connected with the switch K3 and then connected with the width indicator in parallel, and one end of the width indicator, the dipped headlight D2 and one end of the high beam D3 are connected with a power supply through the switch K1.
The scheme is a specific connection structure among the dipped headlight, the high beam and the width indicator.
As a further aspect of the present invention: fuses are arranged among the light combination assembly, the automobile instrument panel and the power supply.
The fuse is arranged to play a role of safety protection.
As a further aspect of the present invention: the backlight brightness of the automobile instrument panel is provided with a high grade and a low grade.
The low grade is 5-20% of the total backlight brightness of the automobile instrument panel, and the high grade is 40-80% of the total backlight brightness of the automobile instrument panel. According to the scheme, a preferable reference value is provided for the daytime mode and the nighttime mode, so that the adjustment of a user is facilitated, and the situation that the backlight brightness is too low or too high is avoided. The scheme does not relate to software and programs, the brightness adjustment can be directly set by the existing equipment, and the low-grade and the high-grade are only explanation on the backlight brightness.
The utility model has the advantages that: the utility model provides an anti-dazzle mesh liquid crystal instrument has utilized the characteristic of indicating wide lamp, and the free switching of effectual realization motormeter dish screen brightness no longer needs artifical regulation screen brightness, also avoids simultaneously because of the too extreme condition of intensity in a poor light that external brightness change leads to greatly, and then the effectual anti-dazzle mesh function of having realized.
