Abstract
The utility model relates to a lighting device used for electronic books. The lighting device comprises a frame, an electronic book screen, a power supply, an SMD LED light bar and a light guide plate, wherein the frame is provided with a groove arranged around the periphery of the frame, and the inside wall of the groove is fixed with the SMD LED light bar; the side wall of the light guide plate where a plurality of sequentially arranged textures are coated on the back surface of a transparent material to form a layer is right opposite to the SMD LED light bar; and the bottom layer of the frame is provided with the electronic book screen. In a place with insufficient light, reading can also proceed by adopting the lighting device, that a panel of the whole electronic book uniformly gives out light can be ensured and the light emitting effect is similar to that of a liquid crystal screen. The lighting device has the advantages of novel conception, simple structure, scientific and reasonable property, little power consumption and the like, and has special significance to protection of teen-age eyes.
Description
Technical field:
The utility model relates to a kind of device that adopts led light source, more specifically to a kind of e-book lighting device.
Background technology:
Along with development of electronic technology, this series products of e-book has more and more entered daily life.Electronic Paper is a kind of novel Display Technique, it is by after being coated onto a kind of special electric ink on paper, cloth or other planar objects, people are as long as suitably shocked by electricity to it, just can make hundreds of millions of particle change colors, thereby constantly change pattern and the literal that is manifested according to people's setting.The weak point of the e-book product of main flow is at present: owing to be subjected to the restriction of electronic paper technology, promptly the electronic paper screen body can't be luminous, needs by the reflection extraneous light displaying contents on user's ability normal reading and the identification current screen.In the insufficient occasion of light, as night, the user also needs to add the external lights irradiation for the e-book product.Compare with traditional LCD screen product, user's use has been subjected to bigger restriction, and traditional external lights irradiation also can't reach LCD screen even brightness effect fully, and this is that a urgency is treated improved problem.
The utility model content:
The purpose of this utility model is that a kind of e-book lighting device that need not to rely on extraneous light, guarantees the panel uniformly light-emitting of whole e-book is provided at the prior art weak point.
The purpose of this utility model is to realize by following measure: a kind of e-book lighting device, comprise framework, e-book screen, its special character is to also have: power supply, paster LED lamp bar, LGP, described framework is provided with a groove around its periphery, its groove inside side walls is fixed with paster LED lamp bar, described being covered by transparent material back of the body surface is coated with LGP sidewall that one deck arranges orderly some reticulate patterns over against paster LED lamp bar, and described framework bottom is placed with the e-book screen.
Described LGP is made by acryl.
The long limit of described groove one side madial wall is fixed with paster LED lamp bar.
Described groove one side minor face madial wall is fixed with paster LED lamp bar.
A long limit of described groove one side and a side minor face madial wall all are fixed with paster LED lamp bar.
Described its diode tube pitch of paster LED lamp bar is 0.5～1.2mm.
Described framework upper epidermis is coated with a deck panels, and panel is made by acryl.
Compared with prior art, adopt the e-book lighting device that the utility model proposes, can read equally under the insufficient occasion of light, and can guarantee the panel uniformly light-emitting of whole e-book, illumination effect and LCD screen are similar.The utlity model has advantages such as novel, simple in structure, scientific and reasonable, that power consumption is few, special significance is arranged for the eyes of protecting young people.
Description of drawings:
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
Fig. 1 has provided the utility model example structure schematic diagram.A kind of e-book lighting device, comprise framework 1, e-book screen 2, power supply, paster LED lamp bar 3, LGP 4, described framework is provided with a groove around its periphery, its groove inside side walls is fixed with paster LED lamp bar, described groove inside side walls is the long limit of groove one a side madial wall, also can be to be groove one side minor face madial wall, also can be that a long limit of groove one side and a side minor face madial wall all are fixed with paster LED lamp bar.Described its diode tube pitch of paster LED lamp bar is generally 0.5～1.2mm.Such arrangement is comparatively reasonable, and Ji Kao Account payes attention to energy savings again to abundant, the uniformity of light, has good cost performance.Paster LED lamp bar is fixed at groove one side side wall surface in this example, and its diode tube pitch is 1.0mm.Described being covered by transparent material back of the body surface is coated with LGP sidewall that one deck arranges orderly some reticulate patterns over against paster LED lamp bar, and the light that is penetrated by paster LED lamp bar reflects through reticulate pattern, can be radiated at equably on the e-book screen that the framework bottom places.Described framework upper epidermis can also be coated with a deck panels 5, and panel is made by acryl.In addition, the paster LED lamp bar adjustable resistance of can connecting, the big I of regulating resistance changes the power of paster LED lamp bar light source, is adjusted to the sensation of reader's the most comfortable.
The foregoing description does not constitute restriction of the present utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
