Moonfield has a solid divergent, polar body, and polar body packaging structure. At least, according to the above, the shortcomings of conventional high-power light emission are: The light-emitting diodes are all made of ordinary resin lenses, which make the packaging structure occupy 1241043 and 2 too large, which makes it difficult to use, and has a low degree of freedom in the product. 、 Application = The structure of the assembly converges the divergent light of Tongcai Effect, there is no other special way 4 = 3: structure cannot be reached To the requirements of planarization, 'make the product's flexibility and multi-point light sources to be used as surface light sources, and their light is self-inflicted as a cost.

Please refer to FIG. 2 again, which is a schematic cross-sectional view of a second preferred embodiment of the present invention. The planar optical modulation unit 204 is also similar to a Fresnel lens structure, but it is & optical phase modulation. The system is composed of a series of axisymmetric structural elements (concentric ring structure). By using the theory of binary diffraction optics combined with micro-electro-mechanical process (MEMS), the size of the element structure is between 1 and 5 to produce light sources. Intensity is divided into two parts, and light wave shaping '^ multi-wavelength partial wave'. This principle is based on the structure size and the diffraction properties of light wave fluctuations generated when the light wave is near, and the modulation effect of the diffraction microstructure is achieved. Generally speaking, when Diffraction characteristics can be produced when the structure size diameter is 5 to 0 times the wavelength of human light, in which the planar optical modulation unit 204_span and ring width can be changed according to the wavelength of the corresponding modulated light source. , Or change according to the light source 205 convergence and divergence requirements, or change due to different diffraction patterns, that is, for applications such as light splitting, beam shaping, etc. ^ The plane optical modulation unit 204 also has a plane Of course, we use non-axisymmetric structural elements with diffractive optical phase modulation to achieve this purpose, and the structural efficiency of the 7G piece of non-axisymmetric structure is as follows. Figure 2A is with diffractive optics Phonogram of a phase-modulated non-minus structural element. When the dimension diameter of the non-diffractive diffractive element 为 is 5 ^ 10 times the wavelength of human light, it can cause the incident light to be diffracted to The incident light 丨 the banknote separation points 1 !, 1241043, the focal point ⑴ and the focal point 13, and the focal point u, the focal point 12, and the focal point i3 are the focal points of light, green, and blue respectively. The non-axisymmetric structural element 10 Stereo 2 is shown in Figure 2B, and its efficacy can correspond to the energy flux shown in Figure 2c = Please see _3 again, which is a cross-sectional view of the third preferred embodiment of the present invention in which the plane optical modulation is shown. The unit 304 is a gradient refractive index changing lens structure. In the system, the mixed medium is mixed with ytterbium to make the refractive index show a gradual layer distribution, and the design is moderate enough to cause the light source 305 to deflect to the desired position. Planar optical modulation The distance between the lens and the lens is changed into a gradient and the rate change lens will be described in Figure 3A), and at the same time to achieve the purpose of flat overall packaging, for example, we can mine metal thin film (gold or silver) on the resin packaging material and When the voltage is applied, gold ^ is used to exchange ions with the sodium (Na) contained in the glass to change the refractive index of the glass, and then the gradient refractive index changes the lens structure. Fan Cheng Figure 3A is a transparent illustration of the gradient rate change of the fortune, and it shows the change of the emissivity of the drug stem with the squat. Press, ladder-shaped contact lens (grin 丨 __ An optical property similar to a traditional lens produced by using the characteristics of material materials = ordinary pieces, which is characterized by a gradient change of the refractive index distribution inside the element ( Along a certain line: = shot as shown in Figure ^ shows the use of controlled refractive index change distribution to achieve a condensing element (corresponding to the traditional convex lens) or astigmatism element. For example, when the gradient index changes the refractive index of the lens with the diameter The effect of the distance is shown in Figure 3A, and the effect of the traditional convex lens can be achieved. The figure 4 shows the schematic diagram of its regular hair lying on the ground, doped with a plurality of side wide-dispersed particles 404. Moreover, the diffusion particles 404 are mixed early and Zhao to achieve the effect of a diffused light source. The structure formed by the packaging material 40 and the diffusion = / Γ can be used as a lens to encapsulate the money body to achieve high power and light emission. Polar body flat package structure.

It can be applied to the back silk towel of large-scale nuclear crystal screens. , Saki low point system expanded to surface light source The degree of difficulty in self-adhesion of light during use can be attributed to points; however, the above are only the best practical paste of the present invention, when the scope of this problem can not be closed, which can be obtained by association, correction: the plane The optical modulation unit is changed from a ring structure to a different perspective, or other packaging materials are used. Those skilled in this field can change the implementation after understanding the gods.
