Automobile instrument panel background light source LED distribution, installation and fixation mechanism

Abstract

The invention discloses an automobile instrument panel background light source LED distribution, installation and fixation mechanism, which includes a support base. A display mechanism is installed above the support base, a connecting shaft is installed at the bottom of the display mechanism in a penetrating mode, the support base is connected with the bottom of the display mechanism through the connecting shaft, and six LEDs surrounding evenly combines a novel structure form by taking one LED as a center; at the same time, N forms of surface array lighting are combined in an equal-interval mode, compared with other lines, surface and array combinations, combination forms are less, and calculating the optimal interval combination with higher relative illumination consistency is easier; andaiming at the circular lighting surfaces of a tachometer and a speedometer, the effective lighting area is improved through the structure, the number of the LED is saved, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of automobile panels, in particular to a distributed installation and fixing mechanism of LED background light sources on automobile dashboards. Background technique [0002] As a window for the driver and the car to communicate information, the car instrument has been developed from scratch, and its functions range from simple to complex, and it is constantly developing and improving. When buying a car, in addition to paying attention to the power and handling of the car, subjective and detailed issues such as the overall appearance of the car, the shape of the headlights, the material of the interior, and the appearance of the dashboard have also become important considerations when buying a car. factor. The instrument panel assembly is like a window, which reflects the running status of the internal mechanism of the vehicle at any time. At the same time, it is the control center of some equipment and the object to...

Problems solved by technology

[0004] The object of the present invention is to provide a distributed installation and fixing mechanism of LED background light source of automobile instrument panel to solve the following disadvantages of the existing distributed installation and fixing mechanism of LED background light source of automobile dashboard in the above-mentioned background technology: The quality of products is uneven, the brightness of the background light (brightness) in the same car varies greatly, and there are even extreme cases where some parts are dazzlingly bright while others are not clearly visible at all; inconsistency in color (chroma) On the other hand, it shows a variety of situations, the same color in the same car presents different levels of color; the single LED point lighting design is designed for the background light of a single button, the speedometer and tachometer of the instrument cluster The area of ​​the button pattern is larger than that of the button pattern. Because the LED is not 360-degree lighting, the light energy is concentrated in a certain angle, and the light efficiency is low, so a single LED cannot meet the requirements of the background lighting, and multiple LEDs need to be used in combination; Driving current can enhance luminous intensity and reduce dark areas, but the increase in brightness will reduce visual comfort and affect the life of LEDs; if the spacing is reduced, the number of LEDs used will increase, and the light efficiency of LEDs cannot be fully utilized, resulting in Product cost rises; when providing lighting for a target surface of a certain size, the linear arrangement of LEDs obviously cannot meet the lighting requirements
