Abstract
The utility model relates to a light guide plate for back lighting of an instrument panel and belongs to the technical field of automobile construction and machining technologies. The light guide plate comprises a light guide surface, a light guide plate bottom surface and light guide feet, wherein the light guide plate bottom surface can produce diffuse reflection; the light guide feet are used for leading light rays and arranged on the light guide plate bottom surface; the light guide plate is installed between the instrument panel and a circuit board; lighting LED (light-emitting diode) lamps are installed on the circuit board and arranged under the light guide feet of the light guide plate; a network point structure is adopted on the light guide plate bottom surface; three or four light guide feet are arranged on the periphery of the light guide plate; lighting LEDs are deviated from a lighting area of the instrument panel; and the light guide plate is made of PMMA (polymethyl methacrylate). According to the light guide plate, the problem of unevenness of the brightness of the front side of the instrument panel is solved, and the quantity of the lighting LED lamps is not increased.
Description
Technical field
The utility model belongs to the technical field of automobile construction and processing technology, particularly a kind of Novel instrumentation console back lighting light conducting plate structure.
Background technology
Combination instrument is an important safety member in automobile, and it is the main parts that driver obtains motoring condition information, and meanwhile, it is also an important ornamental member on automobile.At present, along with the development of automobile industry, consumer not only pays close attention to the function of instrument, also the illuminating effect of instrument is more and more paid close attention to.In order to make, automobile instrument panel is more attractive in appearance and illuminating effect is more soft and graceful, needs the brightness of illumination of instrument more even.So more be conducive to driver to the reading of the information such as the speed of a motor vehicle, rotating speed, also make the interior trim of automobile more elegant in appearance.
The back lighting of present most automobile combination meter is mainly directly in instrument board back lighting with LED lamp.The structure of this instrument back lighting mainly contains following two shortcomings: (1) instrument board front face brightness is inhomogeneous, high at the regional luminance over against LED, and the regional luminance between two LED is low, thereby causes Driver Vision weak effect.(2) this kind of structure is in order to make up illumination uniformity problem, will increase the quantity of back illumination LED, so just greatly increase cost, along with the Fast Growth of Domestic Automotive Industry, domestic automobile inside gadget, in appearance also in continuous innovation, requires also more and more higher to the illumination uniformity of instrument.
Summary of the invention
In order to solve the deficiency of above-mentioned prior art problem, the utility model provides a kind of Novel instrumentation console back lighting LGP and lighting device, realizes instrument board brightness even.
An instrument board back lighting LGP, comprises the light guiding surface that can produce irreflexive bottom surface of light guide plate, be arranged on bottom surface of light guide plate top, by the lead leaded light pin of light guiding surface of source light.
Described leaded light pin comprises footing and light-emitting window.
The periphery of tabula rasa bottom surface is provided with side, and the light-emitting window of leaded light pin is located on side.
Described light guiding surface is the mirror surface structure of polishing.
Described bottom surface of light guide plate adopts uniform lattice point structure.
The material of described LGP is PMMA.
The quantity of described leaded light pin is three or four.
Described leaded light underfooting is provided with LED lamp.
The top of described illuminating LED lamp is that 0.4mm is to 0.6mm apart from the bottom surface height of leaded light pin.
The invention has the beneficial effects as follows: the present invention has had excellent leaded light performance, and the brightness of LED is conducted, and the light of light guiding surface is even, user has good comfort level to the visual effect of instrument, in addition, the present invention reduces the quantity of using LED, can be enterprise and realizes lower production cost.
Accompanying drawing explanation
Fig. 1 light conducting plate structure schematic diagram;
Fig. 2 light conducting plate structure front view;
Fig. 3 light conducting plate structure rear view;
The explosive view of Fig. 4 instrument board backlighting arrangement.
In figure, 1. dial plate, 2. LGP, 3. wiring board combination, 4. illuminating LED lamp, 5. the leaded light pin of LGP, 6. light guiding surface, 7. bottom surface of light guide plate.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present invention, technical scheme.
As Figure 1-3, a kind of instrument board back lighting LGP, the leaded light pin 5 that comprises light guiding surface 6, can produce irreflexive bottom surface of light guide plate 7 and import for light, bottom surface of light guide plate 7 is provided with leaded light pin 5.In order to make illuminating LED lamp 4 depart from the field of illumination of dial plate, make the field of illumination that its direct projection light can not direct irradiation dial plate 1, leaded light pin 5 is located at the position that the field of illumination of dial plate 1 is departed from LGP bottom, be about to the periphery that leaded light pin 5 that the light for illuminating LED lamp imports is arranged on LGP 2, the quantity of leaded light pin 5 has three to four, illuminating LED lamp 4 is placed on below the leg of leaded light pin 5, the quantity of the quantity of illuminating LED lamp 4 and leaded light pin 5 is equal, and the top of illuminating LED lamp 4 is that 0.4mm is between 0.6mm apart from the bottom surface height of leg.The light of illuminating LED lamp 4 enters LGP 2 by 5 conduction of leaded light pin.The back side of LGP 2 is uniform lattice point structure, through leaded light pin, 5 conduction enter after LGP 2 light of illuminating LED lamp 4, because there is uniform lattice point structure at the back side of LGP 2, light will produce diffuse reflection and light can be full of LGP 2 uniformly on the back side of LGP 2 like this.
In order to increase the light guide effect of LGP 2, the front of LGP 2 is set to burnishing surface, the materials'use PMMA (polymethyl methacrylate) of LGP 2, the front uniform irradiation that light will pass through LGP 2 after the diffuse reflection at the back side of LGP 2 is on dial plate 1, just even in the numeral in dial plate 1 front and the brightness of designated symbol like this.
Figure 4 shows that a kind of overall structure explosive view of instrument board backlight illuminating system, comprise mechanical structured member and electronic building brick two parts, after assembling by certain way each other, can reach stabilized structure, reliable in function, the uniform product requirement of illuminating effect.The overall structure of Novel instrumentation console backlight illuminating system comprises dial plate 1, wiring board 3, LGP 2 and illuminating LED lamp 4, described LGP 2 be arranged on dial plate below, described illuminating LED lamp 4 is below LGP 2, and described illuminating LED lamp is arranged on wiring board 3.
