Abstract
The utility model discloses a compound light guide plate has transparency carrier and transparent film, the transparent film printing has a plurality of leaded light points, the transparency carrier has front, the back and four sides, transparent film attached in the back of transparency carrier, open the double -phase right side of transparency carrier has the recess that is used for placing LED lamp strip, the transparency carrier is the glass board. The beneficial effects of the utility model are that: earlier print leaded light point on transparent film, and then have the printing transparent film of leaded light point and transparency carrier to combine to form the light guide plate, will realize more easily on the transparency carrier than prior art direct painting, improved the processing procedure yield, in addition, compare with prior art, the utility model discloses it has the recess that is used for placing LED lamp strip to open in the double -phase right side of transparency carrier, and transparency carrier adoption glass board, makes more multiple beam entering light guide plate of LED lamp strip to make the luminance of LED panel light increase, the light efficiency gets a promotion.
Description
Technical field
The utility model belongs to field of photovoltaic materials, is specifically related to a kind of illumination or display light guide plate.
Background technology
The light efficiency of current LED panel lamp is 50-60lm/W, and light efficiency is lower compared with other light fixtures, and LED lamp tube light efficiency is generally at 80-100lm/W, LED down light efficiency is generally at 80-90lm/W, because LED panel lamp light efficiency is lower, cause whole lamp brightness lower, thus cause irradiated area to reduce.
Existing LED light guide plate, LED lamp bar is placed on two sides or four sides of light guide plate, light beam is made to enter in light guide plate, the material of light guide plate is the acrylic/PC sheet material of optical grade, then with there is high reflectivity and the hitech materials of not extinction, light guiding points is stamped at the acryl plates bottom surface UV screen printing technology of optical grade, optical grade acryl plates is utilized to draw the stop of light on optical grade acryl plates surface sent from lamp, when light is mapped to each light guiding points, reflected light can toward all angles diffusion, then destroy conditioned reflex to be penetrated by light guide plate front, by various density, light guiding points not of uniform size, light guide plate uniformly light-emitting can be made.Such mode Problems existing is: (one) is owing to being placed on two sides or four sides of light guide plate by LED lamp bar, prior art is that LED lamp bar width is greater than light guide plate, part light can not enter in tabula rasa, causes the loss of some light, thus causes light efficiency lower; (2) light guiding points in the light guide plate of prior art is directly printed on the bottom surface of light guide plate, and this technique is very difficult in practical operation, and yield is lower, and therefore cost is high.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of composite light guide plate, and line source can be converted into area source by this composite light guide plate, and the problem that the light efficiency that can solve again prior art existence is low.
The technical solution adopted in the utility model is: a kind of composite light guide plate, there is transparency carrier and hyaline membrane, described hyaline membrane is printed with some light guiding points, and described transparency carrier has front, the back side and four sides, and described hyaline membrane is attached at the back side of described transparency carrier; Two relative side openings of described transparency carrier have the groove for placing LED lamp bar; Described transparency carrier is glass plate.
Preferably, described some light guiding points are printed in described hyaline membrane and are attached in the one side of described transparency carrier.
Preferably, described some light guiding points are printed in the one side of described hyaline membrane away from described transparency carrier.
The beneficial effects of the utility model are: composite light guide plate of the present utility model has transparency carrier and hyaline membrane, hyaline membrane is printed with some light guiding points and is attached at the back side of described transparency carrier, the utility model is first printed on transparent membrane by light guiding points, and then the transparent membrane being printed with light guiding points is combined with transparency carrier, thus formation light guide plate, because light guiding points is printed on transparent membrane, therefore be directly printed on transparency carrier will easilier realize than prior art, improve process rate, even if there is bad scrapping, also only need to scrap transparent membrane part, and transparency carrier part stands intact, therefore, it is possible to reduce costs.In addition, compared with prior art, the utility model has the groove for placing LED lamp bar at two of transparency carrier relative side openings, and transparency carrier is for adopting glass plate, make LED lamp bar more multiple beam enter light guide plate, because the light beam entering light guide plate increases, its derive light also increase, thus LED panel lamp brightness is increased, light efficiency gets a promotion.
Accompanying drawing illustrates:
Fig. 1 is side view of the present utility model.
Fig. 2 is stereographic map of the present utility model.
Embodiment:
Shown in seeing figures.1.and.2, a kind of composite light guide plate, have transparency carrier 1 and hyaline membrane 2, described hyaline membrane 2 is printed with some light guiding points 3, described transparency carrier 1 has front, the back side and four sides, and described hyaline membrane 2 is attached at the back side of described transparency carrier 1; Light guiding points 3 is first printed on hyaline membrane by the utility model, and then the hyaline membrane 2 being printed with light guiding points 3 is combined with transparency carrier 1, thus formation light guide plate, because light guiding points 3 is printed on hyaline membrane 2, be therefore directly printed on transparency carrier 1 will easilier realize than prior art, improve process rate, even if there is bad scrapping, also only need to scrap transparent membrane part, and transparency carrier part stands intact, therefore, it is possible to reduce costs.
Two relative side openings of described transparency carrier 1 have the groove 4 for placing LED lamp bar, described transparency carrier 1 is glass plate, make LED lamp bar more multiple beam enter light guide plate, because the light beam entering light guide plate increases, its light of deriving also increases, thus LED panel lamp brightness is increased, light efficiency gets a promotion.
Described some light guiding points 3 are printed in described hyaline membrane 2 and are attached in the one side of described transparency carrier 1.
Described some light guiding points 3 are printed in the one side of described hyaline membrane 2 away from described transparency carrier 1.
Above-described embodiment is only display and describes ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
