Abstract
The utility model discloses an inclined light guide plate, wherein an inverted trapezoid is formed by the lower side surface of the light guide plate and the upper side surface of the light guide plate; the upper side surface of the light guide plate is vertical to the upper surface and the lower surface of the trapezoid that are in parallel with each other; the lower side surface of the light guide plate is provided with a reflection inclined plane and is disposed in parallel with the reflection inclined plane on the inclined surface of the light guide plate; reflection network points with varying density and size are distributed on the light guide plate; and among the parallel upper surface and lower surface of the light guide plate, the longer one is provided with a single light source. The minimum network point area intensity of the reflection network points is between 12% and 30%; the overall network point intensity of the reflection network points is between 30% and 48%; and the minimum diameter of the reflection network points (11) is between 0.3 and 0.5 mm. The light guide plate is designed to be inclined so that light may be enabled to be emitted from the light emitting surface of the upper side surface through the reflection of the network points after the entry of a light source at the side surface of the light guide plate. The inclined light guide plate enables the light source to enter from a side edge and also has the remarkable advantages of light weight, small thickness, a narrow frame and low power consumption.
Description
Technical field
The utility model relates to photoelectric field, relates in particular to a kind of tilting light guide plate.
Background technology
Light guide plate be the light that utilizes optical grade acryl sheet material to draw to send from lamp in the stop on optical grade acryl sheet material surface, when light was mapped to each leaded light point, reflected light can destroy conditioned reflex by the positive ejaculation of light guide plate then toward all angles diffusion.By various densitys, leaded light point not of uniform size, can make the light guide plate uniformly light-emitting, in the light reflected back light guide plate that the purposes of reflecting slant is the bottom surface is exposed, be used for improving the service efficiency of light.
In the prior art, the light reflection efficiency of light guide plate is low, and its production yields is lower, when light guide plate occurs when bad, can cause entire aphototropism mould to reprocess or scrap, and causes production cost to increase.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of tilting light guide plate.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of tilting light guide plate, it is trapezoidal that described light guide plate downside and upper side formation one are swung to, its upper side is vertical with this trapezoidal up and down parallel two sides, downside is provided with a reflecting slant, in the parallel placement with reflecting slant of described light guide plate skewed surface, and in light guide plate distribute various densitys, reflection site not of uniform size, described light guide plate up and down in the parallel two sides long slightly one side be provided with single Zhi Guangyuan.
Further, the employed material of described light guide plate is optical grade acryl sheet material.
Further, the minimum dot area density in described reflection site is between 12%～30%.
Further, described reflector net is put whole dot density between 30%～48%;
Further, described reflection site 11 minimum diameters are between 0.3～0.5mm.
The utility model has the advantages that: light guide plate adopts the ramp type design, light source in its side enters the back by the reflection of site, luminous energy is penetrated uniformly, therefore from the exiting surface of upper side, the light source design of its side incident has the remarkable advantage of light weight, slim, narrow frameization, low power consumption.
