Description

Optoelectronic device assembly

The present invention relates to an energy harvesting system, and more particularly to a solar energy collection system and an optical lens coupled thereto

1 shows a conventional Light Emitting Diode (LED) package 10 including an optical lens 11, a package base 12, and an LED die 13. The LED package 10 has a longitudinal axis 15 that passes through the center of the optical lens 11. The LED die 13 is disposed on the package base 12. The package base 12 can have a cup (not shown) that can have a reflector (not shown) to reflect light emitted from the bottom and sides of the LED die 13 toward the viewer.

Optical lens 11 is coupled to LED die 13 to receive and direct light from LED die 13. The optical lens 11 has a recess 14 for receiving the LED die 13. The light passing through the pockets 14 of the optical lens 11 can travel over two major optical paths: the first optical path LP1 is the light traveling from the LED die 13 to the surface 1102, and is totally reflected to be approximately 90 with respect to the longitudinal axis 15. The angle of the angle passes through the side wall 1101. The second optical path LP2 is such that light rays are directed from the LED die 13 toward the sidewall 1101 at an angle that would cause total reflection or reflection on the sidewall 1101, and exit the optical lens 11 at an angle substantially non-perpendicular to the longitudinal axis 15. The first optical path LP1 is advantageous for producing an efficient side illumination, while the second optical path may cause a spot of light that the observer does not wish to see.

Therefore, for the LED package or the light-emitting device, in order to avoid the occurrence of the unpleasant light spot of the observer, the thinner optical lens is usually connected to reduce the overall size. In addition, it is also desirable for the LED package or illumination device to provide uniform color light.

In accordance with an embodiment of the invention, an optoelectronic device assembly includes an optical member, a base, and an optoelectronic device. The photovoltaic device is disposed on a surface of one of the bases. The optical component is mounted to the pedestal and/or optoelectronic device. The optical member has a flared portion and a base. The flared deployment includes an upper surface, a side surface, and a lower surface. The upper surface forms a recess of the flared portion that is coupled to the upper surface and is inclined relative to a longitudinal axis that is substantially perpendicular to a horizontal surface of the base. Further, the side surface is curved and is preferably a concave surface. The lower surface is joined to the side surface and the base. The optical member can be radially symmetric to the longitudinal axis.

In accordance with another embodiment of the present invention, the optical member extends longitudinally, preferably bilaterally symmetrically to a longitudinal surface through the optical member. Furthermore, a lens system is formed on the upper surface. In particular, the upper surface is a corrugated surface. The direction of transmission of the corrugations formed on the upper surface may be parallel to this longitudinal direction. The radius of the lens is between about 50 μm and 60 μm. The optoelectronic device is preferably arranged along the direction of propagation of the corrugations.

According to another embodiment of the present invention, a photovoltaic device assembly includes a first auxiliary energy receiver having a first energy inlet and a sidewall for substantially guiding energy away from the first energy inlet; an optical component, optical Coupled to the first auxiliary energy receiver and having a recess toward the first energy inlet; and an optoelectronic device optically coupled to the optical member and receiving energy from the first energy inlet.

Again, this inner boundary can be defined by the optical members described in the various embodiments of the invention.

In another implementation of the present invention, a photovoltaic device assembly includes an optoelectronic device for converting radiant energy into electrical energy; a first auxiliary energy receiver including a first energy inlet, a sidewall, and an inner surface; An optical member for directing radiant energy from the first auxiliary energy receiver toward the optoelectronic device.

Furthermore, a second auxiliary energy receiver can be selectively coupled or optically coupled to the first auxiliary energy receiver. Preferably, the second auxiliary energy receiver is expandable, and more preferably, it can be separated from the first auxiliary energy receiver.

In still another embodiment of the present invention, an electronic device includes a main unit; a display unit is coupled to the main unit; a unit is loaded and removed from the main unit; and The optoelectronic device assembly of the embodiment is combined with the body unit.

Figure 2A illustrates a photovoltaic device assembly 20 in accordance with an embodiment of the present invention. Optoelectronic device assembly 20 includes an optical member 21, a base 22, and a longitudinal axis 24. An optical member 21, such as a lens, is coupled to the base 22 to direct light entering it. The longitudinal axis 24 may or may not pass through the center of the optical member 21. Preferably, the longitudinal axis 24 is substantially perpendicular to a horizontal surface of the base 22.

Figure 2B is a cross-sectional view showing the optoelectronic device assembly 20 of Figure 2A. The photovoltaic device 23 is disposed on one surface of the susceptor 22. The optoelectronic device 23 includes, but is not limited to, an LED die, an incandescent lamp, a fluorescent lamp, a Cold Cathode Fluorescent Lamp (CCFL), a solar cell, and other devices that can emit or receive light and can be coupled to the optical member 21. .

The optical member 21 can be a separate component and coupled to the base 22 by a variety of means including, but not limited to, screwing, snapping, friction fit, adhesive bonding, thermal bonding, and ultrasonic bonding. Alternatively, optical member 21 can be formed on susceptor 22 and/or optoelectronic device 23 in a number of ways including, but not limited to, injection molding and casting.

The optical member 21 is composed of a light transmissive material. The light transmissive material may be a transparent material or a non-transparent material, and the light emitted or absorbed by the optoelectronic device 23 may pass through the transparent material or the non-transparent material completely or partially. Light transmissive materials include, but are not limited to, acrylic resin (Acrylic Resin), cycloolefin polymer (COC), polymethyl methacrylate (PMMA), polycarbonate (PC), polycarbonate / polymethyl methacrylate ( PC/PMMA), Polyetherimide, Fluorocarbon Polymer, and Silicone. The light transmissive material can be imparted with a color such that the optical member 21 functions as the same filter to produce the desired color light.

If the optoelectronic device assembly 20 is placed in an environment filled with air having a refractive index of 1, the refractive index of the optical member 21 needs to be between 1.4 and 1.8 in order to produce the desired light field. Depending on the environment in which the optoelectronic device assembly 20 is located or used, the refractive index of the optical member 21 may also be outside the above range. Preferably, the difference between the refractive index of the optical member 21 and the environment in which it is located is between 0.45 and 0.5.

As shown in FIG. 2B, the optical member 21 includes a flared portion and a base portion 2106. The flared flared portion includes an upper surface 2101 that is formed on the light transmissive material to form a recess 2105, a side surface 2102 that is coupled to the upper surface 2101, and a lower surface 2103 that is coupled to the side surface 2102. The base 2106 is for receiving light from the optoelectronic device 23 and may have a recess 2107 for receiving the optoelectronic device 23. The optical member 21 is used to direct most of the light from the optoelectronic device 23 away from the optical member 21 in a direction generally perpendicular to the longitudinal axis 24 or in a direction that is not directly directed toward the observer. Moreover, to avoid the formation of dark spots above the optical member 21, a small portion of the light from the optoelectronic device 23 can be directed to a direction generally parallel to the longitudinal axis 24 or toward the observer.

The recess 2105 is used to form the upper surface 2101. Preferably, the recess 2105 has a sharp point that lies at the sinking of the upper surface 2101 and is directed toward the optoelectronic device 23. The longitudinal axis 24 may or may not pass through a sharp point. A reflective material or reflective structure may be formed on the recess 2105 to reflect light traveling to the upper surface 2101. The reflective material or reflective structure includes, but is not limited to, Ag, Al, Cu, Au, Cr, a reflective coating, and a Distributed Bragg Reflector (DBR). An anti-ultraviolet material can be formed on the recess 2105 to protect the parts of the device, particularly those sensitive to ultraviolet light, from being deteriorated by ultraviolet light.

The upper surface 2101 is designed as a Total Internal Reflection (TIR) surface for reflecting light entering from the base 2106 and preventing it from exiting by the recess 2105. Even so, there may be portions incident at a particular angle of incidence. Light passes through the upper surface 2101, which varies with the overall design of the optoelectronic device assembly 20. The upper surface 2101 can be a plane or a curved surface having a fixed radius or more than two radii. In particular, the curved surface can have a variable radius that varies with the curved path of the upper surface 2101. Preferably, the radius of the sharp point away from the recess 2105 is greater than the radius near the sharp point.

The side surface 2102 is coupled to the upper surface 2101 and is inclined relative to the longitudinal axis 24 for directing light to the lateral direction of the optical member 21, preferably for directing light to a direction approximately perpendicular to the longitudinal axis 24. If the normal vector of the side surface 2102 is at an angle of about 90 degrees to the longitudinal axis 24, then a relatively high proportion of light passing through the side surface 2102 will travel downward. However, if the side surface 2102 is inclined at an angle relative to the longitudinal axis 24, preferably, the side surface 2102 is facing upward, as shown in Figure 2B, the light traveling downward will be reduced. The side surface 2102 can be a flat surface, a rough surface, or a curved surface. The surface can be concave, convex, or a combination of both. The concave side surface can disperse light rays passing through the surface, and the convex side surface will collect light rays passing through the surface. Rough surfaces can scatter light.

The lower surface 2103 is coupled to the side surface 2102 and the base 2106. The upper surface 2101, the side surface 2102, and the lower surface 2103 form a flared flared portion above the base 2106.

A concave surface 2104 can be formed between the lower surface 2103 and the base 2106. The light from the photovoltaic device 23 may be reflected toward the concave surface 2104 toward the region of the recess 2105, so that the amount of light emitted through the recess 2105 can be increased. If so, the observer will not easily observe dark spots that occur above the recess 2105 of the optical member 21 of the optoelectronic device assembly 20.

A recess 2107 can be formed in the base 2106 to accommodate the optoelectronic device 23. The shape of the pocket 2107 is preferably formed into a conical or pyramidal shape. The sharp point of the cone or pyramid can point to the sharp point of the recess 2105. The deck 2108 of the base 2106 can be a horizontal, curved, or beveled surface. The light rays may be refracted by tilting at an angle to advance substantially perpendicular to the longitudinal axis 24.

Figure 2C is a cross-sectional view showing the optical member 21 in accordance with a preferred embodiment of the present invention. In order to make the picture clear, some outlines and labels in Fig. 2C will be omitted. As shown in Fig. 2C, the optical member 21 is assumed to be symmetrical to the longitudinal axis 24, and preferably has a diameter D of about 105 mm and a height H of about 14 mm. The angle of the cusp of the notch 2105 can vary between A1 and A2, where A1 is 30 degrees and A2 is 180 degrees, preferably A1 is 50 degrees and A2 is 145 degrees. The angle A3 between the side surface 2102 and the longitudinal axis 24 can vary between 5 and 20 degrees. The angle A4 of the cusp of the pocket 2107 can vary within 180 degrees, preferably between 90 and 140 degrees. The slope A5 of the table top 2108 can vary within 60 degrees, preferably within 10 degrees. The radius R1 of the side surface 2102 can vary within 20 mm, preferably within 10 mm. The radius R2 of the concave surface 2104 can vary within 10 mm. The above dimensions may be adjusted in accordance with the ratio of the optical member 21 and the specific design.

Fig. 2D shows a light trace of light from the emission point P in the base and passing through the optical member 21. The light trace L1 is emitted from the emission point P to the upper surface 2101, and changes direction to the lower surface 2103 or leaves the optical member 21 due to one or more total reflections, and is finally refracted at the curved side surface 2102 to horizontally exit the optical member. twenty one. The light trace L2 is emitted from the emission point P, and after being totally totally reflected by the concave surface 2104 and the upper surface 2101, it is refracted at the curved side surface 2102 to horizontally leave the optical member 21. The light trace L3 is emitted from the emission point P toward the slope of the mesa 2108 and is refracted to horizontally exit the optical member 21.

The shape of the optical member 21 may be elliptical, circular, or rectangular from the top view. If the optical member 21 is radially symmetrical with respect to the longitudinal axis 24 passing through the center of the optical member 21, the shape of the optical member 21 in the upper view is circular. At this point, the longitudinal axis 24 will pass through the sharp point of the notch 2105. If the optical member 21 is bilaterally symmetrical with respect to the longitudinal plane dividing the optical member 21 into two identical portions, the shape of the optical member 21 in the upper view may be elliptical, circular, or rectangular. At this time, the longitudinal axis 24 is located on the longitudinal plane and passes through the sharp point of the recess 2105.

In the present embodiment, the upper surface 2101 of the optical member 21 is formed as a corrugated surface. The corrugations 2109 of the upper surface 2101 can surround the longitudinal axis 24, as shown in Figure 3A, or outwardly from the deepest point of the notch 2105, as shown in Figure 3C. Figures 3B and 3D are top views of the two corrugated surfaces, respectively. The corrugations 2109 can be formed by a plurality of convex lenses. The convex lens may have a radius of 50 μm to 60 μm.

Figure 4 is a perspective view showing still another embodiment of the present invention. The light-emitting device 30 of the present embodiment includes an optical member 31, a susceptor 32, an illuminator 33, and a vertical surface 34. The optical member 31 has a cross section similar to that of the optical member 21 described above. The difference between the optical member 31 and the optical member 21 is that the optical member 31 is formed on a longitudinal direction 35 and passes through the longitudinal surface 34. The longitudinal direction 35 is perpendicular to the cross section of the optical member 31. The longitudinal faces 34 may or may not pass through the centerline of the optical member 31, and are preferably substantially perpendicular to one of the horizontal planes of the base 32.

Fig. 5B is a top view showing the light-emitting device shown in Fig. 5A. As shown in Fig. 5A, the light-emitting device 30A has a composition similar to that of the light-emitting device 30 shown in Fig. 4 except for the corrugations 3109 formed on the upper surface of the optical member 31A. As shown in FIG. 5B, the corrugations 3109 are advanced along a transfer direction 3110. The direction of transmission 3110 is the direction of corrugation transfer, preferably parallel or approximately parallel to longitudinal direction 35, although other directions are acceptable. The illuminator 33 may be disposed below the optical member 31A, preferably in a direction parallel to the transfer direction 3110.

As shown in FIG. 6, a photovoltaic device package or assembly 20 in accordance with an embodiment of the present invention includes an optical member 21, a susceptor 22, an optoelectronic device 23, and a first auxiliary energy receiver 40. For a detailed description of the optical member 21 and the susceptor 22, reference may be made to the foregoing embodiments. In addition to the light-emitting elements such as LEDs and laser diodes, the photovoltaic device 23 of the present embodiment can be selected, in particular, from light-receiving elements such as solar cells and photo diodes. .

The optical member 21 is disposed or optically coupled to the first auxiliary energy device 40. The first auxiliary energy receiver 40 has a first energy inlet 4001, a side wall 4002, and an inner surface 4003. The first auxiliary energy receiver 40 can provide a higher energy flux or density of the optoelectronic device 23 than a non-packaged optoelectronic device 23, such as a solar cell that is not equipped with any additional concentrators. If the optoelectronic device 23 can convert radiant energy into electrical energy, the first auxiliary energy receiver 40 can be used to collect radiant energy entering the first energy inlet 4001, such as: sunlight, ultraviolet light, infrared light, visible light, X-ray, and gamma. Rays, etc.

The sidewall 4002 of the first auxiliary energy receiver 40 is preferably constructed as a reverse truncated conical shape. In other words, the cross-sectional area of the first energy inlet 4001 is greater than the cross-sectional area of the other end of the receiver 40. However, the first auxiliary energy receiver 40 may also be formed as a truncated pyramid or a semicircle. Moreover, the side wall 4002 is combined with the inner surface 4003 as a compound parabolic reflector (CPC) or a power series concentrator. The inner surface 4003 of the sidewall 4002 can be arbitrarily selected to form or be combined with at least one of a reflective material, a reflective structure, a scattering material or structure, and combinations thereof. Reflective materials are, for example, aluminum, silver, copper, gold, chromium, tin, iron, nickel, manganese, tungsten, bronze, or alloys or combinations thereof.

Furthermore, the inner surface 4003 can be formed as at least one of a paraboloid, an elliptical surface, a hyperboloid, and a power series surface.

Specifically, the optical member 21 has a side surface 2102, a notch 2105, and a pocket 2107.

As shown in Figures 2B and 2F, the inner volume of the pocket 2107 can be formed as a pyramid or a semi-circle. Further, the pocket 2107 can include a surface 2110 formed as a convex profile. This convex upper surface 2110 helps to focus the radiant energy from the first energy inlet 4001 to the area just in, close to, or about the optoelectronic device 23. Additionally, the contour of the upper surface 2110 can be formed as a concave, planar, beveled, corrugated, or any combination of the above. Although the optical member 21 is fitted to the first auxiliary energy receiver 40 as shown in Fig. 6, the embodiment is not limited thereto. A predetermined spacer or gap may be formed between the first auxiliary energy receiver 40 and the optical member 21. Also, a filling material 4010 may be formed in a part or all of the free space between the first auxiliary energy receiver 40 and the optical member 21. Methods of forming fill material 4010 include, but are not limited to, deposition, coating, spraying, tamping, ejecting, absorbing, attaching, bonding, mating, and locking. Filler material 4010 can be selected from the group consisting of gases, liquids, and solids. Gas systems such as air and inert gases. Liquid systems such as water, oils and solvents. Solids such as oxides, semiconductors, metals, ceramics, and plastics.

7A through 7D illustrate a plurality of optoelectronic device packages or assemblies 20 in accordance with other embodiments of the present invention. The main difference between the 7Ath to 7th and 6th figures is the type of optical member used. The optical member 21A of Fig. 7A has an upper portion 211A and a lower portion 212A. The side surface 2102A of the upper portion 211A is similar or identical to the side surface 2102 of Fig. 6. The lower portion 212A can be mated with the first auxiliary energy receiver 40. The optical member 21B of FIG. 7B has a side surface 2102B that can be geometrically mated completely or partially with at least a portion of the first auxiliary energy receiver 40. Specifically, the side surface 2102B is formed into a smooth contour. The side surface 2102C of the optical member 21C of Fig. 7C has a concave state. The optical member 21D of Fig. 7D has an upper portion 211D and a lower portion 212D. The upper portion 211D is formed in a funnel shape and has an end portion 2102D. The end 2102D can be considered to be a deformation or miniaturization of the side surface 2102. The lower portion 212D is physically in contact with the upper portion 211D. Further, as shown in FIG. 8, the optical member 21 may be selected from a Fresnel lens, a plano-convex lens (as indicated by a broken line), a biconvex lens (not shown below), and a positive One of a positive meniscus lens, a negative meniscus lens, a plano-concave, a biconcave lens, and a total internal mirror (TIR lens) random combination. Also, optoelectronic device 23 is selectively received in recess 2107 having upper surface 2110. The contour of the upper surface 2110 can be selectively formed into a concave shape, a flat surface, a beveled surface, a corrugated shape, or any combination of the above.

As shown in FIGS. 9A and 9B, a photovoltaic device package or assembly 20 in accordance with yet another embodiment of the present invention includes a photovoltaic device 23, a first auxiliary energy receiver 40, and an optical member 50. The optical member 50 is disposed or optically coupled to the first auxiliary energy device 40. The optoelectronic device 23 is optically coupled to one end of the optical member 50 and is preferably coupled to one side opposite the first energy inlet 4001. The optical member 50 of Fig. 9A is formed into a conical shape or a pyramid shape. The contour of the cone may be selected from one of a paraboloid, an elliptical surface, a hyperboloid, and a power series surface, or any combination thereof.

FIG. 9B illustrates an assembled view of the first auxiliary energy receiver 40 and the optical member 50. The internal space of the first auxiliary energy receiver 40 can be virtually divided into a first stage inlet 4020 and a second stage inlet 4030. Most of the components of optical component 50 are preferably disposed within second stage inlet 4030. In other words, none or only a few of the components of the optical member 50 are arranged in the first stage inlet. The radiant energy entering the first energy inlet 4001 can be moved down from the first stage inlet 4020 to the second stage inlet 4030. In addition, if the radiant energy is subjected to at least one of reflection, refraction, scattering, and steering in the first auxiliary energy receiver 40, the radiant energy may be moved up from the second stage inlet 4030 to the first stage inlet 4020. In some embodiments, radiant energy can even move back and forth between one or both of the first stage inlet 4020 and the second stage inlet 4030.

The interior space of the first auxiliary energy receiver 40 can be defined by an inner boundary 4040, an outer boundary 4050, and an upper boundary 4060. Inner boundary 4040 is defined by optical members. The outer boundary 4050 is defined by the side walls 40, and more specifically by the inner surface 4003 or between the optical member 50 and the side wall 4002 that is not permeable to radiant energy. The upper boundary 4060 is defined by the outermost surface of the first energy inlet 4001. Preferably, for radiant energy that can be absorbed by optoelectronic device 23, inner boundary 4040 is permeable and outer boundary 4050 is impermeable. The penetration of the inner boundary 4040 depends on the material or surface structure of the optical member 50. The value of the permeability is about 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, 10%, 5%, or between 99.99% and 5%. The construction of the outer boundary 4050 typically forms at least one of the reflection and scattering functions outside of the inner boundary 4040. For example, as described in the foregoing embodiments, the outer boundary 4050 is formed by a reflective or scattering material or structure formed over the inner surface 4003.

Moreover, the methodology for explaining the embodiments of Figures 9A and 9B can also be applied to the embodiments of Figures 6, 7A through 7D, and Figure 8. The light transmissive materials forming the optical members 21, 21A-21D, and 50 include, but are not limited to, glass, acrylic resin, cyclic olefin copolymer (COC), polymethyl methacrylate (PMMA), polycarbonate (PC), polycarbonate/polymethylmethacrylate (PC/PMMA), polyetherimide (PEI), fluorocarbon polymer (Polyetherimide; PEI), and hydrazine Silicone.

As shown in Fig. 10, the optoelectronic device package or assembly 20 of the present invention exhibits the ability to receive incident light at varying angles. As a result of the numerical simulation, light incident on the first energy inlet 4001 at 0° to 50° can be effectively guided by the first auxiliary energy receiver 40 and the optical member 50 to the optoelectronic device 23 of the target. Observing the ray trajectory, most of the light is reflected by the first auxiliary energy receiver 40, but is reflected and refracted by the optical member 50.

In addition to the first auxiliary energy receiver 40, a second auxiliary energy receiver 60A can be selectively integrated in the assembly 20. In detail, the second auxiliary energy receiver 60A is optically coupled to the first auxiliary energy receiver 40, as shown in FIG. 11A. Preferably, the second auxiliary energy receiver 60A has the function of a compound parabolic reflector (CPC), a power series concentrator, or both. Also, the second auxiliary energy receiver 60A can have a reflective inner surface. The contour of the reflective inner surface is formed as at least one of a paraboloid, an elliptical surface, a hyperboloid, and a power series surface. The second auxiliary energy receiver 60A is preferably shaped to be a truncated cone, however, it may also be a truncated pyramid or a semi-circular shape.

In another embodiment of the invention, the telescoping second auxiliary energy receiver 60B is optically integrated with the assembly 20 as shown in FIG. 11B. The telescopic second auxiliary energy receiver 60B is expandable and therefore easier to carry and collect for the user.

A portable electronic device 100 is shown in FIG. The portable electronic device 100 is such as a laptop computer, a mobile phone, a netbook, a music player, a personal digital assistant (PDA), and an electronic dictionary. Preferably, the portable device 100 includes a main unit 101, a display unit 102, and a body unit 103. The main unit 101 is equipped with an input interface, an output interface, or both. Display unit 102 includes a visual message output interface, such as a liquid crystal display (LCD), a light emitting diode, an organic light emitting diode (OLED), or any combination of the above. The body unit 103 can move in and out of the main unit 101. An optoelectronic device 23 and a first auxiliary energy receiver 40 are arranged in or on the body unit 103. The optoelectronic device 23 is electrically connected to the main unit 101, the display unit 102, or both. Moreover, a telescoping second auxiliary energy receiver 60B can be selectively coupled to the first auxiliary energy receiver 40 to provide a higher energy flux or density of the optoelectronic device 23. In one instance, the telescoping second auxiliary energy receiver 60B can be separated from the body unit 103. In addition, the telescopic second auxiliary energy receiver 60B is also built in the body unit 103. Although the invention has been described above, it is not intended to limit the scope of the invention, the order of implementation, or the materials and process methods used. Various modifications and variations of the present invention are possible without departing from the spirit and scope of the invention.
