The specific embodiment
The first embodiment
Please refer to Fig. 1, it illustrates the cutaway view of the columnar luminous module of first embodiment of the invention.Columnar luminous module 100 comprises lamp guide 102, the first sleeve 104, the second sleeve 106, the first light source 108, secondary light source 110, several the first diffusion structure 124.
The first light source 108 and secondary light source 110 are faced respectively first end 112 and the second end 114 and are passed and be located on the first bottom surface 118 and the second bottom surface 122, in order to emission of light, enter the end face of first end 112 and the end face of the second end 114, so, light is entered in lamp guide 102.
The first diffusion structure 124 is located on the first bottom surface 118 and the second bottom surface 122, in order to by the light L1 diffusion of inciding the first diffusion structure 124 to lamp guide 102.Owing to inciding the light L1 of the first diffusion structure 124, with diffusion way, produce the folded light beam of multi-angle, therefore can avoid reflection ray all with single angle inject lamp guide 102 interior after from the whole light leaks of non-exiting surface, therefore can significantly reduce light leak amount and improve light extraction efficiency and the source efficiency of columnar luminous module 100.According to simulated experiment, the columnar luminous module 100 of the present embodiment can reduce by 47.07% light leak amount.
As shown in Figure 1, although those first diffusion structures 124 are formed separated from each other the first bottom surface 118, so this is non-in order to limit the present invention.In an enforcement aspect, in those first diffusion structures 124, at least a portion also can be connected to each other.
The profile of the first diffusion structure 124 can be protruding profile or other profile.The first diffusion structure 124 can be integrally formed with the first sleeve 104 and the second sleeve 106.Say further, take the first sleeve 104 as example explanation, form in the jetting mold (injection molding) of the first sleeve 104 and there is the mould structure corresponding to the external form of the first diffusion structure 124, so, the first sleeve 104, after injection molded, is just formed with the first diffusion structure 124; Or, also can carry out sandblast manufacture craft to the first bottom surface 118, to form the first diffusion structure 124 on the first bottom surface 118.
The second embodiment
Please refer to Fig. 2 (not illustrating the second sleeve and lamp guide), it illustrates the side view according to the columnar luminous module of second embodiment of the invention.For avoiding diagram too complicated, the columnar luminous module of Fig. 2 does not illustrate the second sleeve and lamp guide.In the second embodiment, continue to use same numeral with the first embodiment something in common, do not repeat them here.Columnar luminous module 100 differences of the columnar luminous module 200 of the second embodiment and the first embodiment are, columnar luminous module 200 more comprises the first reflector plate 228 and the second reflector plate (not illustrating).
Although Fig. 2 does not illustrate, so the columnar luminous module 200 of the present embodiment more comprises lamp guide 102, the second sleeve 106, the secondary light source 110 of Fig. 1.
The first reflector plate 228 is located on the first bottom surface 118 of the first sleeve 104 and is covered at least a portion of those the first diffusion structures 124, and this second reflector plate is located at least a portion that those the first diffusion structures 124 were gone up and covered in second bottom surface 122 (the second bottom surface 122 is not illustrated in Fig. 2) of the second sleeve 106, the first reflector plate 228 and this second reflector plate can be by the light reflection that is incident to the first reflector plate 228 and this second reflector plate to lamp guides 102.Wherein, the reflectivity of the first reflector plate 228 and this second reflector plate is about or is greater than 60%.
The thin portion structure of the first reflector plate 228 is below described, this second reflector plate is similar in appearance to the first reflector plate 228, therefore do not repeat to repeat.
The modes such as the first reflector plate 228 can application examples coating in this way, spraying or plating are formed at the first bottom surface 118.
The profile of corresponding the first diffusion structure 124 of the first reflector plate 228 covers the first diffusion structure 124, and thus, the surface of the first reflector plate 228 is formed with the protruding profile corresponding to the profile of the first diffusion structure 124.Due to this projection profile, add the high reflectance of the first reflector plate 228 itself, therefore can by the light that incides the first reflector plate 228 more efficiently diffusion to lamp guide 102.
In addition, the first reflector plate 228 can be mirror reflector plate or diffusion type reflector plate or diffuse reflection type reflector plate.Better but non-exclusively, the first reflector plate 228 is white reflection sheet or silver-colored reflector plate.
The 3rd embodiment
Please refer to Fig. 3 (not illustrating the second sleeve and lamp guide), it illustrates the side view according to the columnar luminous module of third embodiment of the invention.For avoiding diagram too complicated, the columnar luminous module of Fig. 3 does not illustrate the second sleeve and lamp guide.In the 3rd embodiment, continue to use same numeral with the second embodiment something in common, do not repeat them here.Columnar luminous module 200 differences of the columnar luminous module 300 of the 3rd embodiment and the second embodiment are, the first reflector plate 328 of columnar luminous module 300 and the second reflector plate more comprise several the second diffusion structures 332, its in order to by the light diffusion that is incident to the second diffusion structure 332 to lamp guide 102.
Although Fig. 3 does not illustrate, so columnar luminous module 300 also comprises lamp guide 102, the second sleeve 106, secondary light source 110.
The profile of the second diffusion structure 332 can be protruding profile or other profile.The second diffusion structure 332 on the first reflector plate 328 can be integrally formed with the first reflector plate 328.Say further to there is the mould structure corresponding to the external form of the second diffusion structure 332 in the mould of formation the first reflector plate 328.Thus, the first reflector plate 328 is just formed with the second diffusion structure 332 after completing; Or, can carry out sandblast manufacture craft to form the second diffusion structure 332 to the first reflector plate 328.Similarly, second diffusion structure 332 of the feature similarity of the second diffusion structure 332 on the second reflector plate of columnar luminous module 300 on the first reflector plate 328, at this, it is no longer repeated.
In addition, the first reflector plate 328 of columnar luminous module 300 has similar in appearance to the technical characterictic of the first reflector plate 228 of the second embodiment columnar luminous module 200.The technical characterictic of the first reflector plate 228 please refer to the explanation of the second embodiment, and at this, it is no longer repeated.
The disclosed columnar luminous module of the above embodiment of the present invention, arranges several diffusion structures in the bottom surface of sleeve, can, by the light diffusion that is incident to diffusion structure to lamp guide, to reduce light leak, also can increase source efficiency and the light extraction efficiency of columnar luminous module.In an enforcement aspect, columnar luminous module also can comprise the reflector plate of high reflectance, and more light leak, to reflect more light, is reduced in its bottom surface of being located at sleeve, significantly promotes source efficiency.
In sum, though in conjunction with above preferred embodiment, disclosed the present invention, it is not in order to limit the present invention.Be familiar with in the technical field of the invention this operator, without departing from the spirit and scope of the present invention, can be used for a variety of modifications and variations.Therefore, protection scope of the present invention should with enclose claim was defined is as the criterion.
