Be to reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to according to its specific embodiment of bendable backlight modular structure, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
Relevant aforementioned and other technology contents of the present utility model, Characteristic can be known to present in the following detailed description that cooperates with reference to graphic preferred embodiment.Explanation by the specific embodiment, when can being to reach technological means and the effect that predetermined purpose takes to get one more deeply and concrete understanding to the utility model, yet appended graphic only provide with reference to the usefulness of explanation, the utility model is limited.
See also Fig. 1, Fig. 2 and shown in Figure 3, Fig. 1 is the stereogram of the bendable backlight modular structure preferred embodiment of the utility model, Fig. 2 is the stereogram of another embodiment of the bendable backlight modular structure of the utility model, and Fig. 3 is the cutaway view along A-A hatching among Fig. 2.The bendable backlight modular structure 10 of the utility model preferred embodiment, it comprises: a light source module 20 and a type flexible leaded light plate 30.
Above-mentioned light source module 20 can be a cold-cathode tube light source module 20 or a LED light-source module 20.When using cold-cathode tube light source module 20, will provide a line source.And when using single LED light-source module 20, then can provide a spot light, if when using a plurality of LED light-source module 20 simultaneously, also can form line source.
Above-mentioned type flexible leaded light plate 30, it can be a strip or tabular, and all have an incidence surface 31, a reflecting surface 32 and an exiting surface 33, the material of type flexible leaded light plate 30 can be the mixture of a pliability light guide, a silica gel, an epoxy resin or a silica gel and an epoxy resin again.
The incidence surface 31 of type flexible leaded light plate 30 and the combination of light source module 20 direct optically-coupled are for example by the mould injection molding method, with the one-body molded and combination of silica gel and light source module 20.
Because the one-body molded design of incidence surface 31 and light source module 20 so that the element in the bendable backlight module 10 is simplified, reduces whole manufacturing cost.While, the light that therefore sends from light source module 20 can be coupled in the type flexible leaded light plate 30 fully through behind the incidence surface 31 because incidence surface 31 is not have fitting tightly of medium with light source module 20 between the two.In order to avoid producing light leak and light loss, further also can increase the luminous efficiency of bendable backlight module 10.
When the incident ray of light source module 20 after incidence surface 31 enters strip or tabular type flexible leaded light plate 30, reflex to exiting surface 33 and bright dipping by reflecting surface 32.Reflecting surface 32 can have a plurality of catoptric arrangements 321 again, for example: a plurality of reflection protuberances, a plurality of taper bossy body, a plurality of square lattice point structure, a plurality of irregular shape lattice point structure, groove, groove ... etc.By the setting of a plurality of catoptric arrangements 321, can help to control the reflection angle of incident ray, so that all incident raies all can reflex to exiting surface 33.
Simultaneously, this exiting surface 33 of above-mentioned type flexible leaded light plate 30 can be provided with a plurality of micro-structurals 331, for example a plurality of lenticules, a plurality of groove, a plurality of light harvesting prism, a plurality of point-like ridge ... etc.A plurality of micro-structurals 331 act on by a plurality of micro-structurals 331 in order to the light of regulation and control from reflecting surface 32, can be in order to regulate and control the rising angle of light.So that see through the light of exiting surface 33 in the type flexible leaded light plate 30, can present that bright dipping is even or the effect that light is concentrated.
When type flexible leaded light plate 30 is strip, can be applied to undersized bendable backlight modular structure 10.And when type flexible leaded light plate 30 when being tabular, then can be applicable to large-scale bendable backlight modular structure 10.And because it all has the character of deflection, therefore can be according to actual demand flexural deformation, even the object of the out-of-shape shape of can fitting, not limited by shape, thereby increase application.
Seeing also shown in Figure 4ly, is the cutaway view of the 3rd embodiment of the bendable backlight modular structure of the utility model.Type flexible leaded light plate 30 among the 3rd embodiment of the present utility model, its reflecting surface 32 can form and be provided with a metallic reflector 322, increase the amount of light of exiting surface.
Seeing also shown in Figure 5ly, is the cutaway view of the 4th embodiment of the bendable backlight modular structure of the utility model.Among the 4th embodiment of the present utility model, because type flexible leaded light plate 30 has the character of deflection, therefore bendable backlight module 10 will can be applicable to the use of flexural deformation.And when bending is established in 30 formation of type flexible leaded light plate, reflecting surface 32 wherein and exiting surface 33 all will become crooked kenel simultaneously in the lump.
For fear of the light of light source module 20 incidents, because forming crooked kenel, reflecting surface 32 and exiting surface 33 cause the light path distortion, cause producing the problem that the intensity of light source weakens away from the zone of light source module 20.Reflecting surface 32 in the type flexible leaded light plate 30 can arrange respectively a plurality of catoptric arrangements 321 and a plurality of micro-structurals 331 simultaneously with exiting surface 33.
Cooperatively interact by the setting of a plurality of catoptric arrangements 321 with a plurality of micro-structurals 331, so that incident ray is not subjected to type flexible leaded light plate 30 Bending Influences, can be uniformly distributed in the whole bendable backlight modular structure 10, and then produce best luminous efficiency.Therefore, bendable backlight modular structure 10 is can be according to practical application request arbitrarily crooked, and still stablely provides best luminous efficiency.
A plurality of catoptric arrangements 321 that reflecting surface 32 has in the above-mentioned type flexible leaded light plate 30 and metallic reflector 322, and a plurality of micro-structurals 331 that exiting surface 33 has in the type flexible leaded light plate 30, all can select collocation to implement according to actual demand, to reach best effect.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, in the scope that does not break away from technical solutions of the utility model, when the structure that can utilize above-mentioned announcement and technology contents are made a little change or be modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
