Abstract
The invention discloses an automobile meter dial backlight lighting device and relates to the technical field of automobile meter lighting technology. The automobile meter dial backlight lighting device comprises a light box (1), a printed dial (2), a pointer (3), a circuit board (4), a light-emitting diode (5), a light box support (6) and a light body (7). The light box (1) is injection molded by the light box support (6) and the light body (7). The light body (7) is arranged on the upper portion of the light box support (6). The printed dial (2) is arranged on the upper portion of the light box (1). The pointer (3) is arranged on the printed dial (2). The circuit board (4) is arranged on the lower portion of the light box (1). The light-emitting diode (5) is arranged on the circuit board (4). The automobile meter dial backlight lighting device is capable of saving a large amount of light-emitting diodes used for lighting the dial and saving light sources for lighting the pointer due to the fact that lighting of the pointer is taken into account by the design of the light body, avoiding uneven brightness caused by direct lighting of the light-emitting diode, improving product quality and lowering cost.
Description
Technical field:
The present invention relates to the auto meter lighting technical field, be specifically related to a kind of backlighting arrangement of auto meter dial plate.
Background technology:
In the prior art, the backlight of auto meter dial plate directly provided by light-emitting diode, and be even in order to make dial illuminance, and reach brightness requirement, usually needs 6 or more light-emitting diode evenly to be placed on the dial plate below.But because the characteristic of light-emitting diode self, still be difficult to avoid the dial plate brightness directly over the light-emitting diode to be higher than two brightness between the light-emitting diode, for guaranteeing evenly will to increase more light-emitting diode, increased cost of product.
Summary of the invention:
The backlighting arrangement that the purpose of this invention is to provide a kind of auto meter dial plate, it solves the problem that the direct illumination of dial plate light-emitting diode causes the dial plate brightness irregularities, under the prerequisite that meets design requirement simultaneously, reduces cost.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises lamp box 1, printing dial plate 2, pointer 3, wiring board 4, light-emitting diode 5, lamp house supporting rack 6 and light conductor 7, lamp box 1 is formed by lamp house supporting rack 6 and light conductor 7 injection mouldings, and light conductor 7 is arranged on the top of lamp house supporting rack 6, the top of lamp box 1 is provided with printing dial plate 2, pointer 3 is arranged on the printing dial plate 2, and the below of lamp box 1 is provided with wiring board 4, and light-emitting diode 5 is arranged on the wiring board 4.
Described light conductor 7 adopts light transmissive materials to make, and has the characteristics such as light transmittance height, leaded light performance are good.
Principle of work of the present invention: by double-shot moulding technique, light conductor 7 and lamp house supporting rack 6 are combined together, structure is compacter, has avoided owing to exist assembly clearance to cause the light path loss of dial illumination between the two.Simultaneously, light conductor 7 the is integrated light guide structure of dial plate pointer 3 makes meter hand 3 can share the light source of printing dial plate 2 illuminations.
The present invention can save a large amount of light-emitting diodes that is used for dial illuminance, and because the light conductor design has taken into account the pointer illumination, so saved again the light source that is used for the pointer illumination, the simultaneously application of light conductor also can be avoided the problem of the brightness disproportionation that light-emitting diode direct illumination causes, product design is provided, has reduced cost.

The specific embodiment:
With reference to Fig. 1-Fig. 5, this specific embodiment is by the following technical solutions: it comprises lamp box 1, printing dial plate 2, pointer 3, wiring board 4, light-emitting diode 5, lamp house supporting rack 6 and light conductor 7, lamp box 1 is formed by lamp house supporting rack 6 and light conductor 7 injection mouldings, and light conductor 7 is arranged on the top of lamp house supporting rack 6, the top of lamp box 1 is provided with printing dial plate 2, pointer 3 is arranged on the printing dial plate 2, and the below of lamp box 1 is provided with wiring board 4, and light-emitting diode 5 is arranged on the wiring board 4.
Described light conductor 7 adopts light transmissive materials to make, and has the characteristics such as light transmittance height, leaded light performance are good.
The principle of work of this specific embodiment: by double-shot moulding technique, light conductor 7 and lamp house supporting rack 6 are combined together, structure is compacter, has avoided owing to exist assembly clearance to cause the light path loss of dial illumination between the two.Simultaneously, light conductor 7 the is integrated light guide structure of dial plate pointer 3 makes meter hand 3 can share the light source of printing dial plate 2 illuminations.
This specific embodiment can be saved a large amount of light-emitting diodes that is used for dial illuminance, and because the light conductor design has taken into account the pointer illumination, so saved again the light source that is used for the pointer illumination, the simultaneously application of light conductor also can be avoided the problem of the brightness disproportionation that light-emitting diode direct illumination causes, product design is provided, has reduced cost.
