The utility model solves the problem that the requirements on meter panel brightness and uniformity of the DIG meter are hard to met, facilitates the arrangement of components on a circuit board, improves the utilization ratio of incident beams, improves the brightness and the uniformity of light on the meter panel , and saves LED cost.
Description
Technical field
The utility model relates to physical field, relates in particular to automobile instrument, particularly a kind of instrument light conducting plate structure.
Background technology
Along with the digitrend of automotive electronics, display screen is applied on the fascia by increasing.Conventional instrument through LED direct backlight mode, illuminates dial plate usually.For satisfying the homogeneity of brightness, need to install more LED; Simultaneously, LED takies more space on circuit board.For novel DIG (DISPLAY IN GAUGE) instrument panel, promptly display screen is arranged on the middle instrument panel of dial plate, owing to receive the restriction in space, instrument panel dial plate below does not have the space to place more LED, the dial plate brightness and the homogeneity that are difficult to meet the demands.
Summary of the invention
The purpose of the utility model is to provide a kind of instrument light conducting plate structure, and described this instrument light conducting plate structure will solve that the DIG instrument panel is difficult to realize dial plate brightness and inhomogeneity technical matters in the prior art.
This instrument light conducting plate structure of the utility model; Comprise a transparent injection-molded parts, wherein, described transparent injection-molded parts comprises a leaded light ring and at least one leaded light post; Described leaded light ring is circular; Any described leaded light post all is connected on the outer rim of leaded light ring, and the leaded light post is perpendicular to the sagittal plane of leaded light ring, and extend the below of the leaded light post guide ring of light; The junction of leaded light post and leaded light ring is provided with the light reflecting slant, is provided with a plurality of hemispheric salient points in the downside of leaded light ring.
Further, the number of leaded light post is two.
Further, the sphere diameter of any two hemispherical salient points equates.
Further, the arranged outside of the junction of leaded light post and leaded light ring has the inclined-plane, is arranged with a plurality of rib teeth in the inclined-plane in parallel, and described rib tooth extends to the upper side of leaded light ring from the upper end of leaded light post.
Further, corresponding central angle is 90 ° between two leaded light posts and the leaded light ring junction.
Further, the downside of leaded light ring is provided with a LGP support.
The principle of work of the utility model is: before the leaded light ring was installed in the LGP support, the leaded light post passed the position that the LGP support extends rearward to LED.Display screen in the DIG instrument is arranged on the circular hole position at leaded light ring center.The light that LED sends imports the leaded light post into, and the light reflecting slant of leaded light post and leaded light ring junction reflects into leaded light ring with light; A plurality of hemispherical salient point in the leaded light ring downside reduces the loss of light; Improve the emergent light of leaded light ring upper surface, simultaneously, through changing light path; Increased the homogeneity of dial plate brightness, light penetrates from the end face of leaded light ring equably.
The utility model and prior art are compared, and its effect is actively with tangible.The utility model is provided with circular leaded light ring in the DIG instrument; Display screen in the DIG instrument is arranged on the circular hole position at leaded light ring center; Outer rim rear side at the leaded light ring is provided with the leaded light post; Utilize the leaded light post will be, penetrate from the end face of leaded light ring equably again from the luminous leaded light ring that is delivered to of LED.The utility model has solved that the DIG instrument panel is difficult to realize dial plate brightness and inhomogeneity technical matters in the prior art; Made things convenient for the layout of components and parts on the circuit board; Improved utilization of incident light; Put forward by force the brightness and the homogeneity of dial plate glazing, only needed to have saved the cost of LED once the brightness and the homogeneity that can realize requirement to two LEDs.

Embodiment
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the instrument light conducting plate structure of the utility model comprises a transparent injection-molded parts; Wherein, Described transparent injection-molded parts comprises a leaded light ring 2 and at least one leaded light post 1, and described leaded light ring 2 is circular, and any described leaded light post 1 all is connected on the outer rim of leaded light ring 2; Leaded light post 1 is perpendicular to the sagittal plane of leaded light ring 2; Extend the below of the leaded light post 1 guide ring of light 2, and leaded light post 1 is provided with the light reflecting slant with the junction 3 of leaded light ring 2, is provided with a plurality of hemispheric salient points 4 in the downside of leaded light ring 2.
Further, the number of leaded light post 1 is two.
Further, the sphere diameter of any two hemispherical salient points 4 equates.
Further, leaded light post 1 has the inclined-plane with the arranged outside of the junction of leaded light ring 2, is arranged with a plurality of rib teeth 6 in the inclined-plane in parallel, and described rib tooth 6 extends to the upper side of leaded light ring 2 from the upper end of leaded light post 1.
Further, corresponding central angle is 90 ° between two leaded light posts 1 and leaded light ring 2 junctions.
