Description
Technical field
This utility model relates to a kind of light guide plate, particularly relates to a kind of light guide plate being applied on automobile instrument.
Background technology
Light guide plate one word comes from the translation of English LightGuidePlate, and its generation is for supporting display panels.Liquid crystal display requires by backlight module due to the characteristic of its non-self luminescence to manifest its brightness.At present, along with the expansion of range of application, each display field such as light guide plate application display screen, instrumental panel, owing to luminescent system is generally point source, such as LED, and whole display system especially bias light what is desired is that uniform brightness, and this is accomplished by light guide plate, utilize light diffusing, make light uniform, be converted into uniform area source by point source, and by reasonably design, reduce LED quantity as far as possible, reduce energy loss.Light guide plate is that the PMMA/MMA/PC using optical grade makes, and then with the hitech materials with high reflectance and not extinction, the bottom surface UV screen printing technology at light guide plate stamps light guiding points.The light that the backlight that light guide plate is drawn sends stops in light guide plate surface, and when light is mapped to each light guiding points, then reflection light toward all angles diffusion, can destroy conditioned reflex and penetrated by light guide plate front.By various densitys, light guiding points not of uniform size, light guide plate uniformly light-emitting can be made.
In prior art, but without the light guide plate being specifically designed to automobile instrument, and different according to using environment, the design of light guide plate also can be different.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, this utility model provides one to be specifically designed to above automobile instrument, uniform light guide plate rational in infrastructure, guide-lighting.
The technical scheme in the invention for solving the technical problem is:
A kind of automobile instrument light guide plate, including light introducing section, reflecting part and flat light guide plate portion, described light guide plate portion is laid with guide-lighting site, described light introducing section arranged outside light source, described light introducing section and the mutually right setting in light guide plate portion, connect the reflecting part bending setting of light introducing section and light guide plate portion, and the focal position of described reflecting part is set to light source point, along with light guide plate portion from light source point from the close-by examples to those far off, described guide-lighting site is by dredging densely covered setting.
As preferably, along with light guide plate portion from light source point from the close-by examples to those far off, the descending laying of size of guide-lighting site.
As preferably, guide-lighting site is set to formed objects.
As preferably, light source point is positioned at light guide plate portion near reflecting part, and described guide-lighting site is provided in round a little.
As preferably, the central angle that the segmental arc of reflecting part is corresponding is 45 °.
Light guide plate is arranged to three parts, and including light introducing section, reflecting part and light guide plate portion, light source is arranged on the downside of light introducing section, after light imports from light introducing section, reflect into light guide plate portion through reflecting part, scattered out by the guide-lighting site in light guide plate portion, and penetrate uniform light.The central angle that the segmental arc of light introducing section and the mutually right setting in light guide plate portion, reflecting part bending setting, and reflecting part is corresponding is 45 °.The focal position of reflecting part is light source point, then guide-lighting site is from the close-by examples to those far off by dredging close setting from light source point.The size of guide-lighting site can be evenly sized, it is also possible to is from being from the close-by examples to those far off descending setting from light source point.Namely guide-lighting site is close by dredging to both sides respectively from light source point, descending setting.
By the reasonable setting of guide-lighting site, guide-lighting uniform, daylight rate is high, as long as then adopting less LED just can project uniform bias light.
The beneficial effects of the utility model are in that: this utility model passes through the Reasonable Arrangement of the rationally setting to light conducting plate structure and guide-lighting site, it is achieved light guide plate light-conductive rate height, leaded light are uniformly.

Fig. 2 is perspective view of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1, 2, a kind of automobile instrument light guide plate, including light introducing section 3, reflecting part 4 and flat light guide plate portion 1, light guide plate portion is laid with guide-lighting site 2, described light introducing section arranged outside light source, light introducing section 3 and the mutually right setting in light guide plate portion 1, connect light introducing section bent setting with the reflecting part 4 in light guide plate portion, the focal position of described reflecting part is set to light source point, and along with light guide plate portion from light source point from the close-by examples to those far off, described guide-lighting site 2 is dredged to gather and set.Along with light guide plate portion from light source point from the close-by examples to those far off, the descending laying of size of guide-lighting site or guide-lighting site are set to formed objects.Light source point is positioned at light guide plate portion near reflecting part, and described guide-lighting site is provided in round a little.The central angle that the segmental arc of reflecting part 4 is corresponding is 45 °.
Light guide plate is arranged to three parts, and including light introducing section 3, reflecting part 4 and light guide plate portion 1, light source is arranged on the downside of light introducing section, after light imports from light introducing section, reflect into light guide plate portion through reflecting part, scattered out by the guide-lighting site 2 in light guide plate portion, and penetrate uniform light.The central angle that the segmental arc of light introducing section and the mutually right setting in light guide plate portion, reflecting part bending setting, and reflecting part is corresponding is 45 °.The focal position of reflecting part is light source point, then guide-lighting site is from the close-by examples to those far off by dredging close setting from light source point.The size of guide-lighting site 2 can be evenly sized, it is also possible to is from being from the close-by examples to those far off descending setting from light source point.Namely guide-lighting site is close by dredging to both sides respectively from light source point, descending setting.Being provided with breach on light introducing section 3, the edge of light guide plate is provided with waveform.
By the reasonable setting of guide-lighting site, guide-lighting uniform, daylight rate is high, as long as then adopting less LED just can project uniform bias light.
This utility model passes through the Reasonable Arrangement of the rationally setting to light conducting plate structure and guide-lighting site, it is achieved light guide plate light-conductive rate height, leaded light are uniformly.
