Definitions
- This invention is related to luminescent lamps, especially the means that project the light they emit, being composed of an optical device, which is suitably arranged on an electro-luminescent light source, particularly on the luminescent surface of the lamps.
- White Light fluorescent and LED's for general use in lighting produces an increase in the light emitted by said lamps without affecting their IRC Chromatic Reproduction index.
- the light is produced by discharging light of short wavelength and high energy on a layer of luminescent material, which is formed by a mixture of elements of the group of rare earths and others commonly called matches, where it becomes light of shorter wavelength and less energy.
- the light of short wavelength is emitted by the mercury contained in its interior in the ultraviolet range, specifically in the bandwidth that goes from 185 nm to 365 nm, with a peak at 254 nm
- the semiconductor diode produces blue-violet light, in the bandwidth of 400 to 470 nm mainly, with a peak at 450nm.
- the invention is not capable of converting the total high-energy light produced inside it into a shorter wavelength light, emitting a large part of said light in the range of 380 nm to 470 nm, which corresponds to the blue color - violet, where the human eye has a low relative luminous efficiency, which translates into a low use of the emitted light and therefore of the energy they consume.
- European Patent Application EP 1 746 126 Al of kawakatsu Akira of January 24, 2007, describes a selective wavelength blocking material to be applied to different types of lamps, which is formed by a mixture of zinc oxide ( ZnO) and oxide Titanium (Ti02), creating a basic trigonal structure with which a total blockade of the emission in the UV range and partial in the beginning of the visible range is achieved, specifically up to 400 nm - 430 nm, this with the intention, by a on the one hand, to avoid the damage caused by the UV radiation emitted by said lamps to the objects illuminated by them, and on the other hand to avoid the attraction of insects, offering a minimum loss of the original light emission of the source, however, this device It does not teach a use of blocked radiation or a distribution of ZnO, in the proportions that are to be protected to achieve an increase in the light emission of the lamp and obtain longitudinal wave parameters such as those presented in the present invention.
- Japanese Patent Application JP 5 725 738 Al of Itou Hideni of February 10, 1982 describes a blocking layer disposed on a fluorescent lamp to prevent the emission of Infrared radiation from 1000 nm, by means of a layer of block composed of a ZnO material or Indium oxide (IN2O3), which allows to control the emission of said radiations in the fluorescent lamps, but without exerting any influence on the emission of visible light, as in the present invention.
- a blocking layer disposed on a fluorescent lamp to prevent the emission of Infrared radiation from 1000 nm, by means of a layer of block composed of a ZnO material or Indium oxide (IN2O3), which allows to control the emission of said radiations in the fluorescent lamps, but without exerting any influence on the emission of visible light, as in the present invention.
- Japanese Patent Application JP 2006332000 Al of Kawakatsu Akira of December 7, 2006 describes an ultraviolet protective material for luminescent lamps, where a luminescent shielding material formed by a Zinc Oxide (ZnO) base is provided as the main compound, doped with at least one particle of tungsten (W), manganese (Mn) or europium (Eu), which prevents the emission of unwanted ultraviolet radiation while converting it into visible light with a peak of 450 nm - 550 nm, so it is obvious to any person skilled in the art that this device has a very different operating principle from the present invention and that it cannot be applied to white light LED lamps because they do not emit ultraviolet radiation, so does not teach a distribution of ZnO and in the proportions that are to be protected to obtain wavelength parameters such as those presented in the present invention.
- ZnO Zinc Oxide
- Still another object of the invention is to provide an optical device capable of retro-reflecting the luminescent layer of the source, most of the light of short wavelength and high energy to be converted into longer wavelength light and lower energy for said luminescent layer, resulting in an increase in the total light emission of at least 20%, without modifying the Chromatic Reproduction Index (IRC) of the source.
- IRC Chromatic Reproduction Index
- the present invention which consists of a reflector and a optical filters, which operate in combination.
- the reflector is a metallic surface, diffuse or specular, with a reflectance not less than 98%, with dimensions and geometry according to the lamp to be affected, whose function is to reflect the greatest amount of light towards the work plane, while the filter optical is a rigid, transparent structure Rent in visible light, in a geometric shape and dimensions also according to the lamp to be affected, made of organic or inorganic material, which serves as a substrate on which a layer of zinc oxide is applied.
- the zinc oxide layer is a nano structure of Zinc Oxide wires, with specific parameters of Filling Reason, Network Parameter, and Height, so that said optical filter is achieved as a partial light reflector in the bandwidth from 380 nm to 530 nm and as an antireflective element in the range of 531 nm to 1100 nm, simultaneously.
- the optical filter and the luminescent source are mechanically attached to the reflector, with the active zinc oxide nano layer facing the luminescent layer of the source, in this way the visible light of short wavelength and high energy will be mostly retroreflected towards the phosphor of the luminescent layer of the source, where it discharges its energy on its outer layer to be converted into longer wavelength, resulting in an increase in the total light emission of at least 20% unmodified its IRC Index, since the violet blue light emitted by the lamp is not completely eliminated.

- this energy can be harnessed, retro-reflecting it back to the luminescent layer of the source, where it discharges its high energy and becomes light of greater wavelength, for which the relative light efficiency of the eye is greater, this is achieved by this nobel Optical Assembly, whose multi-layer optical filter is capable of retro-reflecting most visible high-energy light in the range of 380 nm to 530 nm, towards the luminescent layer of origin, without eliminating it completely, and at the same time transmitting practically without loss the light corresponding to the rest of the visible range and the near infrared.
- FIG. 4a shows a sectional and off-scale view of the first preferred mode of this Optical Assembly, precisely when applied to a conventional linear fluorescent lamp, commonly used in lighting, the same whose spectral distribution curve in the visible range is shown in FIG. 2.
- the optical filter 7 has a cylindrical shape and its inner diameter is greater than that of the fluorescent lamp 1 by at least 2 mm, which allows it to be housed inside it with a co-axial handle, and its length covers the entire luminescent surface 2 of this.
- the lamp 1 and the filter 7, are mechanically fastened to the metal reflector 3, by means of two support bases 11 each arranged at each end of the fluorescent lamp 1, and also serve as a means of the electrical supply coming from the ballast (Not shown). ).
- the optical reflector 3 It has a parabolic shape and is a diffuse or specular metal surface, with a thickness of 0.2 mm to 1 mm, with a diffuse or specular reflectance not less than 98%, whose function is to reflect towards the work plane, the light generated by the lamp 1, its dimensions are consistent with the dimensions of the lamp to be affected.
- the PIG. 4b shows a sectional view of the optical filter 7 containing inside the fluorescent lamp 1, decoupled from the support bases 11 and the optical reflector 3.
- Said optical filter 7 is formed by a substrate 9, made of an inorganic material transparent, for example lime or borosilicate soda glass, or an organic one, for example of the thermoplastic methyl methacrylate resin or a polycarbonate, with a thickness of 0.1 nm to 1 mm, on which a layer 8 is applied with a 1.5 to 3 micrometer thickness containing Zinc Oxide, which is the active layer of the optical filter 7.
- a substrate 9 made of an inorganic material transparent, for example lime or borosilicate soda glass, or an organic one, for example of the thermoplastic methyl methacrylate resin or a polycarbonate, with a thickness of 0.1 nm to 1 mm, on which a layer 8 is applied with a 1.5 to 3 micrometer thickness containing Zinc Oxide, which is the active layer of the optical filter 7.
- Zinc Oxide has high reflectance in the Ultra Violet (UV) range and high transmission in the visible range
- the mostly reflective range of Zinc Oxide has been slightly extended until the beginning of the visible range, this is achieved by configuring it as a nano wire structure s Zinc Oxide, with Network Parameter of 200 nm to 400 nm, Fill Value of 0.5 to 0.8 and height of 1 to 2 micrometers, in the PIG. 5 shows a perspective view of said nano wire structure (NEH) of the layer 8, applied on the substrate 9, to form the optical filter 7.
- the refractive indexes of the substrate 9 and the layer 8 are displaced in phase 180 , ° whereby it is achieved that the optical filter 7 behaves simultaneously as a reflective and anti-reflective surface simultaneously, depending on the wavelength of the light passing through it.
- the luminescent lamp 2 emits a beam of light 14 and it reaches the optical filter 7, the wavelength components greater than 540 nm pass through it practically without losses, but most of the blue-violet components 14 'in the 380 nm range to 520 nm are retro reflected back to luminescent layer 2 by the nano-wire structure (NEH) of zinc oxide of layer 8, where they discharge their high energy and are again emitted with a wavelength greater than 14 " which allows them also crossing the layer 8 and the substrate 9 practically without losses, this results in a greater amount of light emitted in wavelengths where the human eye has a greater relative luminous efficiency, which translates into a greater amount of lumens per watt consumed Thanks to the fact that the optical filter 7 does not fully reflect the visible high energy light in the range of 350 nm to 450 nm, the blue-violet colors are not completely eliminated, and therefore the Chromatic Reproduction index of the 1 fluorescent lamp, not only is not reduced, but slightly increases from 80.3% to 81.55%.
- the optical filter 7, shown separately in FIGS. 4c and 5, has the following optical properties: reflectance from 60% to 90% in the range whose wavelength ranges from 380 nm to 490 nm; from 60% to 30% in the range of 491 nm to 500 nm; from 30% to 10% in the range of 501 nm to 530 nm and from 10% to 0% in the range of 531 nm to HOOnm, and 60% to 90% absorbency in the range whose wavelength ranges from 380 to 490 nm; from 60% to 30% in the range of 491nm at 500 nm; from 30% to 10% in the range of 501 nm to 530 nm and from 10% to 0% in the range of 531 nm to 1100 nm.
- FIG. 6 The relative spectral distribution of the same fluorescent lamp of FIG 2 is illustrated, operating with the optical device described in the present invention.
- FIG. 7 a sectional view of the present invention is shown when applied to a linear Module of White Light LED lamps and commonly used in lighting. Some dimensions have been exaggerated for a better understanding of its operation.
- the module 3 is a printed circuit on which several white light emitting semiconductor diodes (LED) 1 are mounted, arranged linearly along it in an equidistant manner.
- LED white light emitting semiconductor diodes
- Each LED 1 is formed by a short wavelength light emitting semiconductor 10, on which a luminescent layer 2 is applied, the light emitting semiconductor 10 produces blue-violet light in the bandwidth of 400 nm to 470 nm, this light is discharged on the luminescent layer 2, where it becomes light of different longer wavelengths, which when mixed produce apparently white light, however a large amount of the light energy produced by the light emitting semiconductor 10, passes through the luminescent layer 2 without being transformed, as shown in FIG. 8, this graph is described in detail the emission of light energy along the visible spectrum of said set of LED 's, and as seen, the 450nm peak reaching presents 100% of the emission relative to that wavelength, however according to FIG.
- the relative efficiency of the human eye is barely 2.5%, therefore most of this high energy light is also being wasted.
- module 3 which is attached to reflector 4 by means of screws 6, reflector 4 is a rigid and flat metal part, with a thickness of 0.1 mm to 3.0 mm, depending on the power of the LED module to be affected , with a diffuse or specular reflectance minimum of 98%.
- the Optical Filter 7 is coupled, at a minimum distance 13 not less than 2 mm to allow the dissipation of the heat generated by the light-emitting semiconductor of short wavelength 10, and prevent overheating, as well as premature deterioration of the luminescent layer 2.
- the optical filter 7 has a semicircular shape with a diameter twice the width of the linear module of LED White Light lamps and with two horizontal lateral wings arranged at the ends of the semicircle of at least 2 mm wide forming a single piece in the form of omega.
- optical filter 7 acquires a semicircular shape, with a diameter twice the width of the linear module of LED lamps of White Light, and has two wings horizontal sides arranged at the ends of the semicircle of at least 2 mm wide forming a single piece in the form of omega and as in the previous mode is formed by a substrate 9, made of a transparent inorganic material, for example lime soda glass or borosilicate, or an organic one, for example of the thermoplastic methyl methacrylate resin or a polycarbonate, with a thickness of 0.1 mm to 1 mm, on which a layer 8 with a thickness of 1.5 to 3 micrometers containing Oxide is applied Zinc, which is the active layer of the optical filter 7.
- a transparent inorganic material for example lime soda glass or borosilicate
- an organic one for example of the thermoplastic methyl methacrylate resin or a polycarbonate
- Zinc oxide has high reflectance in the Ultra Violet (UV) range and high transmission in the visible range, however
- the mostly reflective range of Zinc Oxide has been slightly extended until the beginning of the visible range, this is achieved by configuring it as a nano structure of Zinc Oxide wires, with a Network Parameter of 200 nm at 400 nm, Fill Value of 0.5 to 0.8 and height of 1 to 2 micrometers, in FIG. 5 shows a perspective view of said nano structure (NEH) of the layer 8, applied on the substrate 9, to form the optical filter 7.
- the refractive indexes of the substrate 9 and the layer 8 are displaced in phase 180, ° whereby it is achieved that the optical filter 7 behaves simultaneously as a reflective and anti-reflective surface simultaneously, depending on the wavelength of the light passing through it.
- linear module of LED White Light lamps is arranged outside the geometric focus of the semicircular optical filter and the reflector is 50% wider than the linear module of LED White Light lamps and has the same length as this.
- the optical filter 7, illustrated in FIGS. 7 and 9, which is shown in detail in FIG. 5, has the following optical properties: reflectance of 60% to 90% in the range whose wavelength ranges from 380 nm to 490 nm; from 60% to 30% in the range of 491nm at 500 nm; from 30% to 10% in the range of 501nm at 530 nm and from 10% to 0% in the range of 531 to 1100 nm, and absorbency from 60% to 90% in the range whose wavelength ranges from 380 to 490 nm; from 60% to 30% in the range of 491 nm to 500 nm; from 30% to 10% in the range of 501nm at 530 nm and from 10% to 0% in the range of 531nm at 1100 nm.
- FIG. 10 shows the new spectral distribution in the visible range produced by the same Linear Module 3 of White Light LED lamps of FIG. 6 when affected by this novel Optical Device.
