Description

[0001] LIGHTING SYSTEM, LAYER OR COVER AND MANUFACTURING METHOD

[0002] Field of application of the invention

[0003] This invention relates to a lighting system that converts light from an undesired spectrum into light from a region of the spectrum that does not overlap with the portion to be attenuated or eliminated, with lower energy within the visible spectrum, and maximizes efficiency and desirable lighting characteristics; layer or cover and manufacturing method.

[0004] Background of the invention

[0005] Currently, there is growing awareness about the harm caused by exposure to high-frequency visible light at night in humans, animals, and plants. This light as a whole is commonly referred to as "blue light." This light encompasses the colors perceived by light waves with wavelengths between 300 and 500 nm, that is, the range of light from near ultraviolet, through violet and blue, to turquoise. This growing awareness is due to the fact that the presence of this group of light, called "blue light," at night ("blue light" hereafter), affects the circadian rhythm of living organisms—as well as the negative effect of blue light present at night on astronomical activity and the ability of people to view stars and celestial objects at night.Given the above, it is the so-called blue light, which is considered part of the unwanted spectrum, that we want to reduce or eliminate totally or partially.

[0006] Nowadays, the systems, structures and methods used for lighting, for example, public roads, both vehicular and pedestrian, and building facades and interior lighting, do not allow reducing the amount of unwanted light emitted by the light source, according to the need.

[0007] SUBSTITUTE SHEET (RULE 26) of the area where it is installed, and in turn maintain a high luminous efficiency, since they can only block the emission of blue light and cannot convert unwanted light frequencies into light in the rest of the spectrum.

[0008] Indeed, current lighting systems that seek to control, reduce or block blue light from the light source eliminate the unwanted blue flux, presenting high energy losses from the original light source.

[0009] The present invention seeks to reduce the amount of unwanted light according to the needs of the area in which the lighting systems are installed, but without wasting the energy of the blue light that is desired to reduce or eliminate, but rather using part of that energy to emit light in the rest of the visible spectrum. In this way, the luminous flux of the entire system is maximized, since less energy losses are generated due to the flow originating from the unwanted spectrum being converted into useful light, instead of transforming it into energy that is not part of the visible spectrum, mainly heat (all this energy that does not become part of the visible spectrum will be considered as heat from now on for the purpose of simplification).

[0010] In accordance with the above, there is a need in the state of the art to have a lighting system that converts the flow of unwanted light into useful flow in other frequencies of the visible spectrum, which maximizes the efficiency and desirable characteristics of lighting, which reduces the amount of unwanted light according to the need of the area in which said lighting system is installed, without totally eliminating the energy from the unwanted light, but rather converting part of the light energy from the original source into light in the rest of the visible spectrum, thus maximizing the luminous flux of the entire system.The latter is because the energy losses resulting from converting the unwanted flow to other frequencies are lower than the losses that occur when using a filter in the traditional way, since the latter only act by converting the energy of the unwanted spectrum into heat instead of converting the energy of the unwanted light to other light frequencies.

[0011] Current solutions to this problem are of three types. One is through discharge luminaires specially made for this purpose (low-pressure and high-pressure sodium bulbs, for example). In these, it is a bulb, and the gas present in the bulb, that gives it the radiation spectrum. The second type is LED technology, using so-called "Amber" LEDs, which are constructed so that they do not emit blue light without the need for an additional layer. These LEDs are less efficient and have other unattractive characteristics: low CCT (Correlated Color Temperature) and low CRI (Color Rendering Index). On the other hand, there are physical filters, which are superimposed over the light source, but their sole purpose is to block blue light; they do not deliberately seek the fluorescent effect achieved with this invention.

[0012] When reviewing and analyzing the state of the art, among the closest documents related to the subject of the present invention, we can cite Patent Registration No. 64030, emanating from Chilean Invention Patent Application No. 201901412, which describes a reflector and an optical filter that increases the total light emission without modifying the CRI of the source, which does not present the technical elements of the technology under study, presenting a technical application different from the invention of the present application, which fails to solve the technical problem thereof. Likewise, it is possible to mention Patent Registration No. 55561 , emanating from Chilean Invention Patent Application No. 201501799, which corresponds to a lighting unit that minimizes the light scattered outside the area of ​​interest that also does not present the technical elements of the present invention, and does not constitute an obstacle to it.Continuing with the state of the art subject matter of the present invention, document TW202034039 describes a display device that includes a display panel and a backlight module. The backlight module includes a plurality of white LEDs. This system does not present the technical elements and does not solve the technical problem of the present invention, which is why it does not correspond to a document that affects the patentability requirements of this technology.

[0013] Finally, it is possible to cite as state-of-the-art in the technical field of the present invention document CN204459912, which discloses a table lamp with eye protection. The table lamp consists of a lamp holder, a lamp post, and a lamp base. This document does not present the technical means of this invention and does not solve the technical problem addressed by it, as it only discloses a table lamp with eye protection.

[0014] In short, as can be seen in the state of the art, previously cited and described, there is no effective solution to the technical problem posed, which is the need for a lighting system that converts part of the energy of the unwanted light from the original source into light in the rest of the visible spectrum, which maximizes the efficiency and desirable lighting characteristics, which decreases the amount of unwanted light according to the need of the area in which said lighting system is installed, without totally eliminating the energy coming from the unwanted light but rather converting part of the energy of the light from the original source into light in the rest of the visible spectrum, maximizing the luminous flux of the entire system.

[0015] Objectives and summary description of the invention

[0016] The main objectives of the present invention consist of a lighting system that converts the unwanted light flow into useful flow in other frequencies of the visible spectrum, that maximizes the efficiency and desirable lighting characteristics, that decreases the amount of unwanted light according to the need of the area in which said lighting system is installed, without totally eliminating the energy coming from the unwanted emission but rather converting the light frequencies of the original source into light in the rest of the visible spectrum, maximizing the luminous flow of the complete system because the energy losses coming from converting the unwanted light flow to other frequencies are less than the losses that occur when using a filter in a traditional manner, since the latter act only by blocking the spectrum instead of converting unwanted light energy to other light frequencies; layer or cover and manufacturing method.

[0017] Detailed description of the invention

[0018] The basis of this patent application is a lighting system that converts unwanted light into useful light at other frequencies, maximizing efficiency and desirable lighting characteristics; the layer or cover; and the manufacturing method.

[0019] The system, layer or cover and method of the present invention allows converting the unwanted light flux into useful flux at other frequencies, and maximizes efficiency and desirable lighting characteristics.

[0020] Likewise, the system, layer or cover and method of this innovation allows the amount of unwanted light to be reduced according to the needs of the area in which said lighting system is installed, without totally eliminating the energy from the emission of unwanted light, but rather converting part of the light energy from the original source into light in the rest of the visible spectrum, maximizing the luminous flux of the entire system because the energy losses from converting the unwanted light flux to other frequencies are less than the losses that occur when using a filter in a traditional manner, since the latter act only by blocking the spectrum instead of converting the energy of the unwanted light to other light frequencies. This energy conversion in which part of the luminous flux is absorbed and reemitted in another part of the light spectrum is called fluorescence.

[0021] To facilitate the understanding of the structural and functional characteristics of the present invention, by way of illustration and not limitation, the following figures are described:

[0022] Figure 1: shows an overview of the system of the present invention.

[0023] Figure 2: shows the initial characteristic curve of a manufacturer (prior art).

[0024] Figure 3: shows the light curve using an embodiment of the system of the present invention (which does not allow more than 1% of blue light to pass through).

[0025] Figure 4: shows the initial curve of the light source without using the system of the present invention.

[0026] Figure 5: shows the light curve using an embodiment of the system of the present invention (which does not allow more than 7% of blue light to pass through).

[0027] Figure 6: shows a graph with the increase in cover temperature for different amounts of blue light (prior art).

[0028] Referring to Figure 1, it is possible to appreciate the parts and pieces comprising the invention. Specifically, first, a highly efficient light source is used. Since light source manufacturers (bulbs, LEDs, etc.) manufacture most of their products for applications where blue light is present, the highest efficiencies are found in products that have some blue light component (for example, all products that emit white light in any of its shades have a non-negligible percentage of blue light). Next, a layer or cover is positioned over the light source.

[0029] This layer or cover is made of a material that is normally highly transparent to the visible spectrum, such as polymethyl methacrylate, polycarbonate, silicone or glass, plus additives that act together as selective light filters.

[0030] In the case of polymers (for example, but not limited to, Polymethylmethacrylate, Polycarbonate and silicone), additives can be added in: the polymer formation process (polymerization) by adding the additives to the monomer, catalyst, a solvent, or a mixture of any of the above, prior to the complete polymerization of the mixture; after the initial polymerization of the polymer, in a polymer reprocessing stage (such as when the polymer is in the form of pellets, which are reprocessed before shaping the part to be used);or through a coating process of the part in the process of being finished, in which the coating corresponds to this same layer or cover, or at least the components of this layer or cover, dissolved in such a way that a thin layer can be applied on the polymer part, either by immersion of the part, immersion, spray or other, to then solidify and remain adhered to the substrate once the solvents evaporate.

[0031] In the case of non-polymeric materials (such as glass), the layer or cover is formed by non-polymeric material plus a layer solidified through the same coating process indicated above, with the difference that the layer is deposited on the non-polymeric material instead of on a polymer.

[0032] Finally, the light from the light source is passed through the modified transparent layer or cover to achieve the desired effect. The layer or cover is a screen formed with one or more additives that act together as a filter for one or more bands, or pass filters. This is because the additives added are filters that act on part of the light spectrum and do not alter the rest of the spectrum: they are frequency-selective filters.

[0033] In addition to the above, the present invention seeks to both reduce or eliminate one or more parts of the spectrum of higher energy waves, that is, one or more sections within the spectrum of the so-called "blue light", and at the same time maximize the amount of light present in the region of the visible spectrum that does not overlap with the part that is desired to be reduced or eliminated.

[0034] Typically, there are different types of light filters that could be applied to light sources. However, the traditional use of light filters is to eliminate part of the spectrum by absorbing unwanted light waves, transforming that energy into heat. Reference is made to Figure 6, which shows a study of how the temperature of a cover that only converts the unwanted spectrum energy of the emitting source into heat, from a cover manufacturer (prior art). This is especially important given that the operating limit of some materials, such as PMMA, is 80°C, and an increase of between 25 and 60°C additional to the normal operating temperature is problematic for the entire system.

[0035] The use of additives with fluorescent properties has the advantage that, on the one hand, it increases the effective light flux in the region of the visible spectrum that does not overlap with the part to be reduced or eliminated, and on the other hand, it emits less heat, causing the layer or cover to heat up less.

[0036] By manufacturing the layer or coating with additives with fluorescent properties, the energy present in the highest energy waves from the light source is partially converted into lower energy waves (longer wavelengths). The result is a greater effective light flux in the region of the visible spectrum that does not overlap with the part to be reduced or eliminated, while the flux in the unwanted spectrum is also reduced or eliminated. Since any additive that eliminates blue light can produce some negligible or even imperceptible degree of fluorescence, and to make a significant difference to that situation, for the purposes of this invention, fluorescence is defined as the property of a material to absorb a flux of blue light (lumens) and re-emit at least 30% of that absorbed flux (lumens) in another range of the visible spectrum.

[0037] On the other hand, by reducing the amount of energy transformed into heat, the power at which the system can operate is greater. This is because lighting systems often have a power limit limited by the maximum allowable temperature of their components; especially the layer or cover, which typically has a maximum allowable temperature limit, which varies depending on the material used. In either case, when using a layer or cover with additives with fluorescent properties, the temperature reached by this layer is lower than that of an identical layer, but with absorbing additives instead of fluorescent ones, which will only reduce or eliminate the same light spectrum range.

[0038] Furthermore, depending on the concentration of additives with fluorescent properties used in the layer or cover, if required, the present invention allows the unwanted spectrum to be eliminated in a percentage less than 100%, allowing sufficient light levels to pass through to meet the maximum blue light requirements required by the user, and thus being able to have a small amount of blue light in the spectrum emitted by the system. This small amount allows the emitted light to reproduce, to a certain degree, shades that would otherwise be nonexistent. This gives it greater color richness, which implies an increase in the color reproduction capacity of the entire system, increasing the system's CRI (Color Rendering Index) and increasing the correlated color temperature, delivering better lighting quality to the user.

[0039] Referring to Figure 2, which shows a manufacturer's characteristic curve (prior art), it is possible to see that if a non-fluorescent layer or cover is used, in this case to block light below 500 nm, the system emits virtually no light below that limit. However, it can also be seen that the manufacturer emphasizes the successful "blocking" of blue light, which entails a loss in lumens of 24% of the light emitted by the light source.This differs from the results of our invention, referred to in Figure 3, in which the equivalent result of a system designed to let through no more than 1% of blue light (according to the Chilean pollution standard in process for which it was designed), has practically no losses (losses in lumens around 1% of the total flow of the light source) and a color reproduction index approximately 27% higher than that obtained by this manufacturer (CRI of 56 of the present invention versus CRI of 44 of the reference manufacturer).

[0040] It is important to note that the reference manufacturer is LEDIL (prior art), the world leader in the manufacture of secondary lenses, and the results indicated in Figure 2 are the most advanced results on the subject presented by this company (for this purpose, equivalent to the layer or cover of the present invention, since it is the element through which the light passes to achieve the modification of the spectrum of the light source).

[0041] Referring to Figure 4, it can be seen the original curve of the light source of Figures 5 and 3, before passing through their respective layers or covers. In relation to Figure 5, and with the objective of demonstrating the versatility of the present invention, it shows the system using a modified layer or cover, for an application in which it is not necessary to let through a maximum of 1% of blue as in the previous example, but rather a maximum of 7% of blue light, and again using the same light source as Figure 4, but this time with this new layer or cover also designed with fluorescent additives, but with the objective of letting through a greater amount of light below 500 nm and with negligible lumen losses (close to 0%) in order to enrich the color, managing to deliver the system a CRI of 70, unlike the reference manufacturer, which delivers a CRI 44.
