DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0053] With reference to FIG. 1 there is shown an embodiment 100 of a GAUSSIAN SURFACE LENS QUANTUM PHOTON CONVERTER 100 comprised of a photon transparent base substrate 101 in communication with a disposed curvilinear (Gaussian) stationary suspension 102 comprised of a photon transparent polymer material, such as an epoxy that is comprised and contains within its stationary suspended form a plurality of the following components disposed and in communication with said stationary suspension; a plurality of quantum dots 105, a plurality of high efficiency phosphors, a combination of a plurality of quantum dots 105 and a plurality of high efficiency phosphors and a plurality of nano-particles 104 of metal, silicon or similar semiconductors from the IIIB and IVB Group of the Periodic Table and any nano-material and/or micro/nano spheres 103 that responds to Rayleigh Scattering and/or Mie Scattering; and a plurality of quantum dots in communication with the plurality of nano-particles 104 in said suspension and said micro spheres 103 in the suspension 102. Said stationary suspension of quantum dots 105 are a selected ratio of red 105R and green quantum dots 105G, and based upon design features selected for a specific selection ratio of red 105R to green 105G; and a plurality of blue quantum dots 106B are not limited from being added to said quantum dot suspension to aid in control of emitted “white” light for desired variations in colour temperature (degrees Kelvin). The quantum dot plurality 105 upon stimulation absorption of ultra-violet (˜450 nm wavelength) photons emitted as incident light from a wide band gap LED (light emitting diode), such as InGaN or similar wide band gap semiconductor, have narrow pass band characteristics over a wide range of temperatures. This makes for a stable condition of maintaining colour temperature or the outcome of such action for producing a “white” LED.
[0054] Another embodiment of said present invention, and relating to FIG. 1, is for the creation of a monochromatic (single colour) LED; and when the quantum dot suspension is comprised of only red quantum dots 105R, the LED is classified as a Red LED; and when the quantum dot suspension 102 is comprised of only green quantum dots 105G, the LED is classified as a Green LED; and when the quantum dot suspension is comprised of only red quantum dots 105B, the LED is classified as a Blue LED. Further is should be obvious to anyone steeped in the art that quantum dots by their very nature, produce a narrow pass band of a specific light wavelength based upon their atomic size, and any plurality combination of different size quantum dots will produce a specific resultant quasi-monochromatic colour range from red, to orange, to yellow, to green, or to blue.
[0055] A specific quantum dot arrangement of at least one or a plurality combination arrangement for a specific desired colour that is formed into the GAUSSIAN SURFACE LENS QUANTUM PHOTON CONVERTER, as illustrated in FIG. 2, is in any instance disposed and in communication with a typical LED arrangement 200 in the form of a single LED die or a plurality of dies in some matrix form. The GAUSSIAN SURFACE LENS QUANTUM PHOTON CONVERTER 102 is a photon-interactive Gaussian surface lens that converts incident photons from a single or a plurality of wide band gap semiconductor class light emitting diode dies, into a secondary emission of photons emanating from a composite photon transparent colloidal stationary suspension of quantum dots, high efficiency phosphors, a combination of quantum dots and high efficiency phosphors and nano-particles of metal, silicon or similar semiconductors from the IIIB and IVB Group of the Periodic Table and any nano-material and/or micro/nano spheres that responds to Rayleigh Scattering and/or Mie Scattering; and a plurality of quantum dots in communication with said nano-particles in said suspension. Further, said GAUSSIAN SURFACE LENS QUANTUM PHOTON CONVERTER 102 in an embodiment shown in FIG. 2 is disposed and in communication with a sub base 102A that can be metallic or thermal plastic and function as a heat sink completing a thermodynamic circuitous path for heat generated by said plurality of electrical current carrying LED dies; and whose circuitous path travels and is in thermal and mechanical communication from LED dies to base 102A and on through the substrate main base 101.
[0056] FIG. 3 relates to the behavior of nanoparticles 104 such as silicon or some other semiconductor material, referenced to Rayleigh-Scattering of incident photons (˜450 nm) emanating from a light emitting diode source; whereby said silicon behaves like a mirror. With said nanoparticles 104 it can be explained that Rayleigh-Scattering having a highly frequency dependent characteristic creates a photon scattering pattern of an electric dipole (antenna) moment expressed as p=qd In the simple case of two point charges, one with charge +q and one with charge −q, the electric dipole moment p is: where d is the displacement vector pointing from the negative charge to the positive charge. Thus, the electric dipole moment vector p points from the negative charge to the positive charge. The electric field of the incident wave (photon) accelerates the charged particle, causing it, in turn, to emit radiation 304 at the same frequency as the incident wave, and thus the wave is scattered. Rayleigh-Scattering is similar to Thomson scattering. Thomson Scattering is an important phenomenon in plasma physics and was first explained by the physicist J. J. Thomson. As long as the motion of the particle is non-relativistic (i.e. its speed is much less than the speed of light), the main cause of the acceleration of the particle will be due to the electric field component of the incident wave, and the magnetic field can be neglected. The particle will move in the direction of the oscillating electric field, resulting in electromagnetic dipole radiation 304. The moving particle radiates most strongly in a direction perpendicular to its motion and that radiation will be polarized along the direction of its motion. Therefore, depending on where an observer is located, the light scattered from a small volume element may appear to be more or less polarized.
Resonating Silicon Mirrors
[0057] In accord with quantum mechanics, each silicon mirror 104 will resonate when excited by soft UV (˜450 nm) light to establish a standing wave emanating within. The precise wave pattern is determined by the wavelength that the incident light has in silicon, which is about one-third of its value in air. Each silicon mirror 104 essentially behaves like an antenna, absorbing light and re-emitting it in a form possessing the symmetry of the standing wave inside the flat silicon nano-structures 104, with said light from said silicon mirrors 104 interfering constructively or destructively, depending on the direction of the incident light.
[0058] Said silicon mirrors 104 resonate like an electric dipole when excited by soft uV light at ˜450 nm. As said silicon mirrors 104 are arranged in a pseudo-random arrangement, emissions from each dipole 104 interfere constructively when light of this wavelength is used and a single beam of light emerges from the same side of the normal as the incoming beam in what is known as negative transmission.
[0059] When 450 nm light hits the silicon mirrors 104, an isotropic standing wave is formed and radiation exits in four orthogonal directions. This in effect increases the amount of photon emission propagated from the quantum dots contained within the said GAUSSIAN SURFACE LENS QUANTUM PHOTON CONVERTER 102 as illustrated in FIG. 2.
[0060] As shown in FIG. 4 with larger spherical glass particles 103, in comparison to said nanoparticles 104 in FIG. 3, there exists a well defined directional radiation pattern likened to a Yagi-Uda Antenna system 303 due to the phenomena of Mie Scattering, which tends to scatter longer wavelengths of light. Ergo, the combined action of short uV photons (˜450 nm), incident of said LED dies and the Stokes shift eminent with monochromatic quantum dot emission, produces longer wavelength light of red and green that is scattered by the Mie solution.
[0061] In one embodiment of said present invention as shown in FIG. 5; a uniform plurality, but not limited to a uniform plurality, of quantum dots of a monochromatic single plurality of quantum dots or a plurality group of different size (monochromatic) quantum dots are in communication and disposed in said stationary colloidal suspension defined as the GAUSSIAN SURFACE LENS QUANTUM PHOTON CONVERTER 102 as illustrated in FIG. 2. It should be obvious to those steeped in the art that the illustrated absorption emission curves 305 for the red quantum dots 105R and the green quantum dots 105G are results of a Stokes shift in photon emission narrow band spectra for the quantum dots being excited by quantum secondary emission within the volume of the stationary colloidal suspension.
[0062] Another embodiment of the present invention is illustrated in FIG. 6 where a uniform plurality, but not limited to a uniform plurality, of quantum dots of a monochromatic single plurality of quantum dots or a plurality group of different size (monochromatic) quantum dots are in communication and disposed in said stationary colloidal suspension defined as the GAUSSIAN SURFACE LENS QUANTUM PHOTON CONVERTER 102 as illustrated in FIG. 2 that engulf a single inline linear array of LED dies 406 disposed and in communication with a substrate 401; and where the stationary colloidal suspension is comprised of a plurality of quantum dots 405 that are either a plurality of single monochromatic characteristic (size) such as red, green, or blue quantum dots or they can exist in a combination pair of red and green quantum dots 405. In addition; the stationary colloidal suspension has disposed and is in common photon communication with the disposed combination of quantum dots 405, and/or high efficiency phosphors; and nano-particles 404 of metal, silicon or similar semiconductors from the IIIB and IVB Group of the Periodic Table and any nano-material and/or micro/nano spheres 403 that responds to Rayleigh Scattering and/or Mie Scattering.
[0063] It should be obvious and understood by those steeped in the art that any embodiment of the present invention is not limited by utilizing a plurality combination of more than one type size of quantum dot; and whereby the size of a quantum dot determines its characteristic monochromatic spectra emission due to incident photon absorption emanating from the intrinsic photon emission of a wide band gap semiconductor fabricated as a light emitting diode. The plurality of a combination of more than one type size of quantum dot is utilized to produce “white” light emitted and propagated from a fabricated light emitting diode, and any selection of a desired “white” colour temperature range given in degrees Kelvin is controlled by careful ratio selection of a plurality of red to green quantum dots. Thus it is established by some prior art that a stand-alone chemical colloidal suspension combination of different size diameter quantum dots, in the range of 2 to 10 nanometres, can produce multi-chromatic colour resultants or that by utilizing a combination of red, green and blue quantum dots a “white” colour will result.
[0064] However, another approach and intention of the present invention is to utilize ultra-small quantum dots 123 (shown in FIG. 7) that are less than 2 nanometres in size diameter.
[0065] Michael A. Schreuder (Dept. of Chemistry at Vanderbilt University) and Sandra J. Rosenthal (Department of Electrical Engineering and Computer Science and Chemistry Dept. at Vanderbilt University) report in a 2010 article titled: “White Light-Emitting Diodes Based on Ultra-small CdSe Nano-crystal Electroluminescence”[1] that white light-emitting diodes fabricated with ultra-small CdSe nanocrystals, which demonstrate electroluminescence from a size of nanocrystals (<2 nm) previously thought to be unattainable. These LEDs have excellent color characteristics, defined by their pure white CIE color coordinates (0.333, 0.333), correlated colour temperatures of 5461-6007 K, and color rendering indexes as high as 96.6. The effect of high voltage on the trap states responsible for the white emission is also described.
[0066] The illustration and graph of FIG. 7 shows that by utilizing a plurality of ultra-small (<2 nm) quantum dots 123 that are disposed within the stationary colloidal suspension volume; and in photon communication with a disposed plurality of glass or polymer micro spheres and a plurality of nano-particles 104 of metal, silicon or similar semiconductors from the IIIB and IVB Group of the Periodic Table and any nano-material and/or micro/nano spheres 103 that responds to Rayleigh Scattering and/or Mie Scattering, correlated colour temperatures in a range of 5461 to 6007 K is attainable. The absorption/emission curve for the ultra-small (<2 nm) quantum dots shows a resultant emission in a range of 430 to 710 nanometres. This embodiment of the present invention allows for a single size diameter (<2 nm) ultra-small quantum dot plurality 123 of the GAUSSIAN SURFACE LENS QUANTUM PHOTON CONVERTER 102 as illustrated in FIG. 2 to produce “white” light from a fabricated wide band gap semiconductor light emitting diode.
[0067] Another embodiment of the present invention is in the utilization of a disposed layered combination of a stationary colloidal suspension volume 500 as shown in FIG. 8 that has disposed on a light emitting diode COB (chip on board) a first photon transparent stationary colloidal suspension volume segment 501 containing a plurality of ultra-small quantum dots 123 (shown in FIG. 7) or a red 105R and green 105G quantum dot plurality ratio (shown in FIG. 5), whereby the first photon transparent stationary colloidal epoxy suspension volume segment 501 is comprised of a plurality of quantum dots, glass or polymer micro spheres, and nano-particles 104 (shown in FIGS. 1 & 3) of metal, silicon or similar semiconductors from the IIIB and IVB Group of the Periodic Table and any nano-material and/or micro/nano spheres 103 (shown in FIGS. 1 & 4) that responds to Rayleigh Scattering and/or Mie Scattering. There is disposed on the first photon transparent stationary colloidal suspension volume segment 501 a second uV (ultra violet) attenuating photon pass band filter member means 501uV that is disposed and in photon communication with the first segment member means 501. There is disposed on second uV (ultra violet) attenuating photon pass band filter 501uV a third disposed inline parallel treble array; consisting of a first disposed strip of a red photon transparent stationary colloidal epoxy suspension volume segment 502R, a second disposed strip blue photon transparent stationary colloidal epoxy suspension volume segment 504B, and a third disposed strip green photon transparent stationary colloidal epoxy suspension volume segment 503G. Whereby all members of said third disposed inline parallel treble array 502R, 504B, & 503G are in photon communication with all first disposed inline parallel treble array, and second uV (ultra violet) attenuating photon pass band filter 501uV.
[0068] The first disposed strip of a red photon transparent stationary colloidal epoxy suspension volume segment 502R contains said plurality of red quantum dots, the nano-particles and said glass or polymer micro spheres; the second disposed strip blue photon transparent stationary colloidal epoxy suspension volume segment 504B contains the plurality of blue quantum dots, the nano-particles and said glass or polymer micro spheres; and a third disposed strip green photon transparent stationary colloidal epoxy suspension volume segment 503G contains the plurality of green quantum dots, said nano-particles and the glass or polymer micro spheres. Disposed and in electrical and mechanical communication with the each individual red strip member means 502R, blue strip segment 504B, and green strip 503G are three disposed individual and electrically separate electrically conductive metallic connexions to the outside world; one said connexion for said red strip 502RC, one said connexion for said blue strip 504BC, and one connexion for said green strip 503GC. Also disposed and in common electrical connexion with all said red 502R, blue 504B, and green 503G strip segments is electrically conductive metallic strip (ground) member means 501Gnd that is the electrical common ground connexion to the outside world.
[0069] In this embodiment of the present invention shown in FIG. 8 it is considered as an action, when a source of incident and intrinsic uV photons (˜450 nm) emanating from a wide band gap light emitting diode disposed and contained within the first photon transparent stationary colloidal suspension volume segment member means 501, by a plurality of propagated ballistic photons from the wide band gap light emitting diode (not shown in figure) “white” light with an effective pass band of from 430 to 710 nm will be produced as a resultant of the action of ultra-small quantum dot 123 absorption and emission. The “white” light with an effective pass band of from 430 to 710 nm will contain an a level of uV (˜450 nm) photons and as another intention of the present invention this uV (˜450 nm) level will be filtered and attenuated to an appreciable amount so as not to be absorbed by the first disposed strip of a red photon transparent stationary colloidal epoxy suspension volume segment member means 502R containing the plurality of red quantum dots, said nano-particles and said glass or polymer micro spheres; the second disposed strip blue photon transparent stationary colloidal epoxy suspension volume segment member means 504B containing the plurality of blue quantum dots, the nano-particles and said glass or polymer micro spheres; and a third disposed strip green photon transparent stationary colloidal epoxy suspension volume segment 503G containing the plurality of green quantum dots, the nano-particles and said glass or polymer micro spheres. This purpose-of-action in filtering out any uV (˜450 nm) photons by the uV filter segment 501uV is to prevent any pre-triggering by the uV (˜450 nm) photons of any of the third segment red strip 502R, or blue strip 504B, or green strip 503G. Another novelty of the present invention is the action of said uV filter film 501uV to attenuate to an appreciable level any uV photons utilized for purposely “not” stimulating the quantum dot strips by absorption and emission action, but rather stimulating the quantum dots contained within the strips by passing an electrical current through each strip in a circuitous path completed by a controllable and programmable electronic voltage source connected to the electrical connexions 502RC, 504BC, & 503GC and electrical common ground connexion 501Gnd disposed and in electrical communication with the red 502R, blue 504B, and green 503G quantum dot strip stationary suspension volumes. It is by this action that another novelty and intention of the invention presents itself by electrically controlling a final colour output from the epoxy composite multi-stationary suspension volume method means 500 thus possessing the capability of producing red, green, blue or white light from a single LED source.
[0070] Another novel embodiment according to the invention is shown in FIG. 9, which is a block diagram for illustrating how various colour combinations are achieved by controlling the enabling and intensity of said colour strips 502R, 504B, & 503G. This preferred embodiment of the invention utilizes a microcontroller 701 that is in communication with an enable and intensity level circuit 702, and microcontroller sends a command signal on an enable/disable line 702EL to a logic control circuit 702En that is in communication with a buffer output stage 702B and whereby buffer output stage 702B is in communication with red quantum dot strip 502R by red signal line 702RL. Further, microcontroller 701 controls on/off enabling and intensity colour levels by sending a programmed enable/disable logic decision signal on its control line 702EL and sends an intensity level command by a control line 702CL to a intensity level circuit (like a digital to analogue converter) 702Int and this signal level is isolated by buffer stage 702B and sent along red signal line 702RL and is in communication with red quantum dot strip 502R; to control the on and off and colour intensity of the red quantum dot strip 502R as determined by an algorithm.
[0071] In addition, this preferred embodiment of the invention utilizes a microcontroller that is in communication with an enable and intensity level circuit 704, and microcontroller sends a command signal on an enable/disable line 704EL to a logic control circuit 704En that is in communication with a buffer output stage 704B and whereby buffer output stage 704B is in communication with blue quantum dot strip 504B by blue signal line 704BL. Further, said microcontroller 701 controls on/off enabling and intensity colour levels by sending a programmed enable/disable logic decision signal on its control line 704EL and sends an intensity level command by a control line 704CL to a intensity level circuit (like a digital to analogue converter) 704Int and this signal level is isolated by buffer stage 704B and sent along blue signal line 704BL and is in communication with blue quantum dot strip 504B; to control the on and off and colour intensity of said blue quantum dot strip 504 as determined by an algorithm.
[0072] In addition, this preferred embodiment of the invention utilizes a microcontroller that is in communication with an enable and intensity level circuit 703, and microcontroller sends a command signal on an enable/disable line 703EL to a logic control circuit 703En that is in communication with a buffer output stage 703B and whereby buffer output stage 703B is in communication with green quantum dot strip 503R by green signal line 703RL. Further, said microcontroller 701 controls on/off enabling and intensity colour levels by sending a programmed enable/disable logic decision signal on its control line 703EL and sends an intensity level command by a control line 703CL to a intensity level circuit (like a digital to analogue converter) 703Int and this signal level is isolated by buffer stage 703B and sent along green signal line 703RL and is in communication with green quantum dot strip 503R; to control the on and off and colour intensity of said green quantum dot strip 503 as determined by an algorithm.
