Abstract
A backlight illuminating device for a dial plate of an automobile instrument relates to the technical field of automobile instrument illuminating and comprises a light box (1), a printed dial plate (2), a pointer (3), a circuit board (4), a light-emitting diode (5), a light box support (6) and a light guide body (7), wherein the light box (1) is formed by the light box support (6) and the light guide body (7) in injection molding mode, and the light guide body (7) is arranged above the light box support (6). The printed dial plate (2) is arranged above the light box (1), the pointer (3) is arranged on the printed dial plate (2), the circuit board (4) is arranged below the light box (1), and the light-emitting diode (5) is arranged on the circuit board (4). The backlight illuminating device for the dial plate of the automobile instrument can save a large number of light-emitting diodes used for dial plate illuminating, and saves light sources used for pointer illuminating due to the fact that design of the light guide body also considers pointer illuminating. Simultaneously, application of the light guide body can also avoid the problem of uneven brightness caused by direct illuminating of the light-emitting diode, so that product quality is improved and cost is reduced.
Description
Technical field:
The utility model relates to the auto meter lighting technical field, is 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, and 6 of needs or more light-emitting diode evenly are placed on the dial plate below usually.But because the light-emitting diode self characteristics, 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,, increased cost of product for guaranteeing evenly will to increase more light-emitting diode.
The utility model content:
The purpose of the utility model provides a kind of backlighting arrangement of auto meter dial plate, and 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, and cost-cutting.
In order to solve the existing problem of background technology; The utility model is to adopt following technical scheme: 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, and 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 process, and has characteristics such as light transmittance height, leaded light performance are good.
The principle of work of the utility model: through double-shot moulding technology, light conductor 7 and lamp house supporting rack 6 are combined together, structure is compact more, 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 the light source that meter hand 3 can shared printing dial plate 2 illuminations.
The utility model 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 the light source that is used for the pointer illumination again; The application of light conductor simultaneously also can be avoided the problem of the brightness disproportionation that light-emitting diode direct illumination causes, and product design is provided, and has reduced cost.

The specific embodiment:
With reference to Fig. 1-Fig. 5; This specific embodiment adopts following technical scheme: 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, and 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 process, and has characteristics such as light transmittance height, leaded light performance are good.
The principle of work of this specific embodiment: through double-shot moulding technology, light conductor 7 and lamp house supporting rack 6 are combined together, structure is compact more, 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 the light source that meter hand 3 can shared 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 the light source that is used for the pointer illumination again; The application of light conductor simultaneously also can be avoided the problem of the brightness disproportionation that light-emitting diode direct illumination causes, and product design is provided, and has reduced cost.
