Abstract

Optical coatings comprising layers of low index materials alternating with layers of high index materials where a plurality of the high index layers resistant to high temperature and/or UV have essentially stable electrical resistivity properties when subjected to ultraviolet portions of the electromagnetic spectrum and/or high temperatures are taught. These coatings are well-suited for today's small high intensity lamps and reflectors used in higher performance projection and lighting systems. These high index materials are chosen to have an index of refraction equal to or greater than 1.8 and a melting temperature greater than 500 DEG C and may be, for example, selected from the group consisting essentially of Ta2O5 or Nb2O5, HfO2, ZrO2, WO2, Mo2, In2O3 or blends thereof. Coatings selectively reflect desired wavelengths, e.g., one coating reflects at least 95% of visible light and transmits at least 80% of infrared.

Description

200809133 (1) Description of the Invention [Technical Field of the Invention] The present invention broadly relates to an optical film coating. More particularly, the present invention relates to a method of making an optical film coating that acts as an interference filter to reflect and transmit an electromagnetic spectrum of a desired wavelength and to resist damage from ultraviolet radiation and/or high temperatures. At the same time, it can keep its own resistance coefficient stable. The optical film coatings of the present invention are useful in a wide variety of Φ applications (e.g., coating a reflective inner surface of a high intensity reflector lamp). [Prior Art] The background information discussed below is intended to better present the novelty and usability of the present invention. This background information is not the prior art adopted. Existing high-performance lamps include a light bulb or wick for providing a light source, a reflector (also known as a mirror cover for guiding light bulbs), and an optical coating for filtering the emission spectrum of the bulb. The existing typical high-performance lighting package φ includes high-intensity discharge (HID) lamps (Fig. la), tungsten halogen lamps (Fig. lb), and other lamps with 塡 inflatable bulbs. Figure 1a shows a typical HID luminaire device 1a, which typically includes a reflector 2 that is typically parabolic, elliptical, or dome-shaped; the reflector has a neck-shaped region 2a that projects rearwardly, wherein The bulb 5 (also known as the wick) has an electrode 7 that is electrically connected for generating and emitting electromagnetic radiation. In addition, the luminaire device further includes a front opening 6a, the opening being covered with a lens 6b through which the light 16 can be projected. An optically reflective film coating 4 is deposited on the reflective inner surface 3; this coating is commonly referred to as -5-200809133 (2) "mirror" for providing a mirror-like surface required for high performance lamps. The bulb current enters the bulb through the first bulb contact 8b; the contact remains electrically connected to the electrical pin 9a, which in turn is electrically connected to the first electrode 7. The second electrode 7 is electrically connected to the second electrical pin 9a, which in turn is electrically connected to the second bulb contact 8b; thus forming an electrical circuit. Compared with fluorescent lamps and incandescent lamps, high-performance lamps produce light with a larger intensity than φ (measured in lumens, where lumens refers to the luminous flux emitted by a single-candle light source) and is relatively small. The color temperature produced in the luminaire is also high; however, high-efficiency lamps produce more harmful ultraviolet (UV) rays. The ray (herein referred to as the ray between the UV and infrared (IR) regions) is generated in the HID bulb due to arcing within the refractory vessel (arc). HID lamps are often used in areas where high light intensity and energy efficiency are required (for example, lighting for sports, large public areas, warehouses, outdoor activity areas, streets, parking lots, sidewalks Φ); recently, these lamps have been used. It has also been found to be used as a headlight for motor vehicles. In addition, HID lamps (especially metal halide lamps) can also be used in small retail stores and residential environments. Indoor gardeners also often need to use HID lamps, especially for crops that require high levels of sunlight (such as vegetables and flowers). The H ID lamp is even used to provide external illumination for the Big Mac Airbus A 3 80, and so far, almost all projection systems use HID lamps as light sources, including projection TVs and high quality images. Projection system. Figure lb shows a typical construction of a tungsten halogen lamp unit lb. The package -6-200809133 (3) typically includes a typical parabolic, elliptical, or ejector 2; the reflector has a neck that can be extended rearward A light bulb 5b (also known as a wick) is mounted in the shape 1 for generating a sum wire. In addition, the luminaire assembly further includes a front opening 6 covered with a lens 6b through which the ray 16 can be projected onto the reflective inner surface 3 by projecting a thin film coating 4 . The venting pin 9a, the current can reach the spiral lamp 糸 φ of the bulb 5b, the second electrical pin 9a, to form an electrical circuit. Tungsten halogen incandescent lamps are different from HID lamps, these incandescent tungsten wicks 7b, and the wicks are sealed in transparent fruit requiring good lumen maintenance, tightness, and such as retail store lighting, stage and projection room lighting, Tungsten halogen lamps are used for medical lighting and residential lighting. Although tungsten is high and has a long service life, it produces more harmful UV rays than any other form. The φ optically reflective film coating is deposited on the inside of the reflector to increase the reflectivity, or it can be deposited on the back of the reflector. The inner surface of the reflector can be referred to as a thin film coating deposition. The thin film coating can be designed to be fully reflective so that all of the electromagnetic spectrum is sufficiently forward reflected. A typical coating design for high-intensity luminaires is called "design. As shown in Figure 2, the tuned coating in the cold-light mirror coating has the effect of a filter; therefore, for the visible spectrum of the bulb , the selected part of which will be reflected forward, and the arcuate anti-region 2 a ' emits an electromagnetic radiation a, the opening comes up. The optical reverses the first electric 糸 7 b. The light has a spiral container inside. There is white light (the museum is based on the halogen lamp efficiency type of incandescent lamp surface; but the light bulb that is known or emitted on the two sides of the light bulb is known as a cold light mirror, the optical dry 5 is generated to leave, away from 200809133 (4 The luminaire device, while most of the IR wavelength is directed to the interior of the luminaire and transmitted through the coating. Since part of the electromagnetic spectrum is a heat source, the visible ray reflected forward is considered "cold" light. More commonly, these coatings are designed to selectively reflect or transmit an electromagnetic spectrum of the desired wavelength. The design elements are required by the optical function being considered and reflected by the optical coating. Long and decided; and typically includes the chemistry of the coating to be deposited, the number of layers of each coating to be deposited, the order in which the different φ coatings are deposited onto the substrate, the thickness of each coating, and the morphology of the coating. The like coating is usually formed by repeatedly interlacing a plurality of low refractive index (π L) materials (such as Si〇x) and high refractive index (??) materials (such as TiOX). It is known that when these coatings are composed of multiple layers T When the L and T/Η coatings are interlaced, a “stop band” is formed, or concentrated in the area where the design wavelength λ G is highly reflective. The high reflectivity design requires the thickness of each coating to reach the design wavelength of four points. One. The design form can be expressed as:

Medium / (HL) m H / Substrate 1 where m is the number of rounds of the multilayer stack, the medium is the material before the ray is in contact with the outer surface of the coating (in this case, the medium is air or equivalent to air), HL Is a layer pair comprising a layer of 7? Η and a layer of 7/L, Η is a layer of η material, L is a layer of material, and 200809133 (5) The substrate is a material deposited by the coating (in this case, the substrate is The reflective inner surface of the reflector). To form a stack that selectively filters a portion of the spectrum, the coating design typically requires a multi-layer stack of multiple layers; wherein the chemical composition, thickness, and location of the layers in a stack are predetermined. . For parabolic or elliptical reflectors (requires "broadband" reflection) φ, the design of the optical coating consists of ? Multiple stacks interlaced with the coating; where the high reflectance regions overlap each other, covering the entire wavelength band and the light incident at a tapered angle. However, the harmful physical and chemical changes caused by the heat generated by the high-intensity bulb and the high UV ray flux produced by the luminaire can damage the available coating (which is made according to Equation 1). The legend provided in Figure 3 shows the flux intensity portion of the UV ray spectrum (ie, the portion that includes the UVA 40 0-3 15 5 region wavelength and is referred to as invisible light), φ UVB 315-280 nm, UVC 2 80 -100 nm, and visible light (400 - 700 nm wavelength region) produced by a typical HID high intensity lamp. The harmful physicochemical changes that these coatings suffer include image attenuation, and the measurement of the resistivity in the deposited coating will decrease. For the design of large-screen rear projection TVs and other projection display systems, the fixtures have become increasingly compact; at the same time, the electrical pins of the bulbs are also connected to the contacts on the deposition surface inside the fixture. In this design, the electrical connections of the pins will be in contact with the reflective coating on the inner surface of the reflector. This means that the coating must be used as an electrical insulator and to maintain the resistivity or resistance 可接受 at an acceptable level during operation -9- 200809133 (6). If the UV photon flux, high temperature, or other factors cause the resistivity of the coating to decrease, the lamp's operating current will flow from a circuit with a small resistance , and may cause a short circuit in the lamp. As such, the optical film reflective coating clearly needs to be designed to reflect or transmit the desired wavelength, to withstand high temperature effects and to be exposed to UV energy, and regardless of UV photon flux and high temperature (usually produced by these lamps) The strength and strength of the ) can maintain its electrical Φ resistance coefficient. SUMMARY OF THE INVENTION The present invention satisfies the current demand for optical coatings in the industry, that is, the design and materials upon which the interference filters are used to achieve the desired wavelengths and withstand high temperatures and exposure to UV, and This is to maintain an acceptable level of electrical resistivity.

In addition, the coating is also suitable for: requiring the coating to reflect and/or transmit electromagnetic energy of the desired wavelength, the coating is resistant to UV and high temperature damage, and the coating is capable of maintaining substantial electrical stability (substantially electrical) Stability means that the coating maintains the resistivity to a high enough level to act reliably as an electrical insulator when it is incorporated into the luminaire, and that the coating can reflect and/or transmit to the desired wavelength. Energy is selectively controlled.

All applications (eg for reflective surfaces coated with high-intensity reflectors). The coating design of the present invention will now be illustrated by the use of a high intensity reflector luminaire coating as an example. This example is intended to be illustrative, and not to limit the scope of the invention. It should be noted that for clarity of presentation, Figures 4a through 4d are limited to -18-200809133 (15) showing two coating stacks on the inner surface of reflector luminaire devices 10, 20, 30 and 40, although understandable in any Any number of stacks can be used in the coating, and any number of layers can be used in the stack; and the number of layers and stacks depends on the optical physical properties that will produce the results, which will be discussed below. Coatings are currently deposited by well-known deposition techniques, including physical vapor deposition, resistive vacuum evaporation, electron gun, ion φ assist, uranium sputtering, cathodic arc, chemical vapor deposition, And low temperature solution deposition; although some less well known or urgently needed techniques can be used. High-intensity reflectors can be fabricated using materials well known in the art or materials that are less well known (eg, glass, ceramic, plastic or metal, or materials with desirable properties but need to be understood).

The illuminating element of the HID reflector luminaire is an arc discharge in a refractory vessel which also contains different gases and metal salts. The refractory vessel is commonly referred to as an arc tube. These lamps produce relatively high pressures and temperatures. Therefore, the damage of existing coatings is partly caused by such high temperatures. φ HID lamps that benefit from the coating of the present invention include mercury vapor lamps, metal halide lamps, Ceramic lamps, low pressure sodium lamps, high pressure sodium lamps, and less common short arc lamps, although the invention is not limited to use only in lamps of the above type.

The gas filled in these bulbs prevents tungsten from depositing on the closed glass tube after vaporization from the spiral wick, thereby regenerating the wick. Tungsten halogen lamps can be used in any field where good lumen maintenance, compact lamp construction, and white light are required. Although tungsten halogen lamps exhibit higher efficiency and have a longer service life, they also produce more UV rays; it is well known that UV-ray Φ lines will make existing reflections compared to any incandescent lamp.

DETAILED DESCRIPTION OF THE INVENTION It is to be noted that the present invention is exemplified by specific examples by different compositions, coating arrangements, thicknesses, chemical compositions, shapes, sizes, shapes and forms. It should be understood that the specific examples described herein are illustrative of the nature of the invention and are not intended to limit the scope of the invention. For example, Figures 4a and 4b illustrate a HID reflector luminaire and a tungsten halogen reflector, respectively; wherein, on the internal reflective surface of each luminaire, the sink φ has the following coating: direct deposition on the inner surface of the luminaire is low refraction Rate 7? L material (such as Si〇2), then deposit a layer of high refractive index 7? Η material (such as Ti〇2), then deposit the next layer of Si〇2 and the next layer of Ti〇2; and so on, until The low refractive index material is repeatedly interleaved with the high refractive index material that follows, reaching a predetermined number of depositions and forming a stack. The pattern of interlacing such coatings is referred to herein as a "type deposition stack." The number of layers in a "type deposition stack", as well as the number of stacks deposited, will depend on the calculated coating to achieve the desired optical properties. The relative relationship between the thickness of the coating, the relative position between the coatings, and the morphology of the coating and the coating is also determined by the optical design principles. The thickness of each coating is defined as: Thickness = Ai(A/4?71cos(9i) Equation 4 where: ! is the refractive index of the material, λ is the wavelength at the center of the band, and Θ is the central angle of the incident light at the cone angle, And Ai is the definition coefficient of the band overlap. During the formation phase of the coating, the two layers of coating stack produce a conventional "cold mirror" reflective coating. As described above, the cold mirror coating can reflect the visible light forward' It emits the luminaire' while also transmitting IR radiation back through the reflector coating and reflector. After depositing the last layer of “type coating stack”, a “type 2 coating stack” can be deposited. “Type 2 coating The stack includes a coating formed by interlacing a low refractive index material (such as si〇2) with a high refractive index material (such as Ta2〇5), wherein the high refractive index material is resistant to high temperature and uv radiation damage. When the coating stack is deposited on a “type coating stack”, unexpected and surprising results can occur. The high refractive index material (such as Ta205) required for this coating design is resistant to high temperatures and UV rays. Damage, the coating it provides It not only reflects the electromagnetic-22-200809133 (19) spectrum of almost all visible wavelengths generated by high-intensity lamps, but also transmits the heat of the IR wavelength, and also resists UV rays and high temperature damage when achieving the above functions. And maintain its resistivity. Table 1 illustrates a preferred example of a preferred optical coating design that follows the principles of the present invention; wherein the first portion of the design, "a type of coating stack," includes two layers. (or alternatively, multiple layers) a stack of low refractive index materials and high refractive index materials interleaved (for example, a first layer is a dielectric material Si〇2 and a second dielectric material Ti〇2 is interleaved; Also, the top stack or the last deposited stack (ie, the "type 2 coating stack, shown in Table 1 at the bottom of the coating list" is by depositing a set of high refractive index materials with low refraction. The rate material sio2 is formed by repeated interlacing of the coating, wherein the high refractive index material is resistant to radiation and high temperature effects (such as Ta2〇5). As mentioned above, this design is surprising. And surprisingly, the resulting coating is able to maintain its resistivity so that the electrodes can be placed in the coating without worrying about φ shorts.

Fig. 5 is a cross-sectional view illustrating a specific example of such an excellent UV-resistant coating design. In this case, there is another excellent example of a coating which is referred to as a "three-type coating stack coating design"; this design contains only multiple and identical "type 2 coating stacks". In particular, for the sake of clarity, Figure 5 is limited to showing a two-layer staggered "type 2 coating stack" wherein each stack 24 has a plurality of individual coatings 22; wherein the individual layers comprise a low refractive index The material L and the high refractive index material η are repeatedly φ interleaved to form a layer. According to this design, the first layer of coating deposited directly on the reflector wall 32 contains a low refractive index coating L. In accordance with the principles of the present invention, one or more layers of other stacks may be deposited on the two-layer stack shown in Figure 5 to achieve a particular spectral reaction design goal. Table 2 shows an example of a "three-type coating stack" coating design comprising a coating formed by repeated interleaving of a low refractive index dielectric material Si〇2 and a high refractive index material Nb2〇5; wherein the high refractive index material It is resistant to UV rays and high temperature damage.

Principle: The optical coatings described herein refer to interference filters; these filters are typically deposited from thin layers such as yttria and yttria or from the compounds listed in -29 200809133 (26) above. On an optical substrate. By carefully selecting the specific chemical composition, thickness, relative position between the coatings, morphology, and number of layers, the present invention produces the first coating in the industry that is resistant to UV rays and high temperature damage (and The coating itself is therefore not damaged), and in addition to being able to tailor the reflectivity and transfer rate of the coating to achieve a variety of desired optical performances, The retention rate is close to 100%. Φ For specific designs used for reflector and bulb spectroscopy, the surface reflectance can be reduced to less than 0.2% by appropriate selection of the materials constructed. The reflectivity can be increased to a level close to 9 9 · 9 9 % to produce a highly reflective (HR) coating. In addition, the reflectance can be adjusted to any particular number, for example, to produce a mirror that is capable of reflecting 90% or more of visible light and capable of transmitting almost all of the IR wavelengths, as shown in Figures 1 and 2. Alternatively, the coating is designed such that the reflective surface reflects only light within a narrow band of wavelengths to produce an optical filter. The diversity of dielectric coatings, φ provides its application in many optical and optical applications, and is also applicable to consumer equipment where high spectral control is required and UV wavelengths are present. It is to be understood that the wavelength at which the reflectance reaches an extremely high level is such that the thickness of the high refractive index coating and the low refractive index coating of the multilayer structure are exactly one quarter of the wavelength. The peak reflectance "f" is a function of the refractive index ratio 値 of the two materials used and the number of layers actually contained in the stack. The peak reflectance can be increased by adding more layers or by using a material with a higher refractive index than 値. For the amplitude reflectivity of a single interface, it can be defined as: -30- 200809133 (27) 0- 夕) (1 + p) where Equation 5

\nl) nS where is the base coefficient, nH is the coefficient of the high refractive index coating, φ is the coefficient of the low refractive index coating, and ΛΓ is the total number of coatings in the stack. In addition, the width of the high reflectance portion of the curve is also determined by the film coefficient ratio 値; the higher the ratio, the wider the high reflection area. Alternatively, the transfer properties of the coating depend on the following factors: the wavelength of the light produced, the refractive index of the substrate (in this case the reflective inner surface of the bulb), the refractive index of the coating or layer, and the thickness of the coating. The angle of the incident ray or the shape of the interface surface, as well as the absorptivity of the coating and substrate. • as shown in Fig. 1, and Fig. 2, which is predictable according to the calculations. The resulting coating deposited according to the principles of the present invention will reflect almost all, if not all, of the wavelengths in the visible region. And can pass most of the IR wavelength; and the experimental results confirm these predictions. -31 - 200809133 (28) Reflectance vs. Wavelength

The first step of the experimental luminaire 60, the luminaire grid 62, the UV sensor 65, the reflector meter, and a test screen equipped with a display screen for displaying the experimental results is to insert a plurality of test probes into the luminaire (attached) Different positions of p inner surface) for measuring surface resistance 値. After the resistance measurement of the coating surface is completed, high-intensity UV light experiments are performed on the coated surface, including ultraviolet light to 400 nm), ultraviolet B (280 to 315 nm) C (100 to 280 nm), and IR ray heat. When the first measurement is performed under natural conditions, the resistance 値 remains unchanged until the resistance is stabilized. At the same time, continuous recording is obtained electronically and displayed in the log chart φ. The results obtained by UV rays and heat on the coating resistance are shown in Figures 3, 4 and 5; these results show exposure to UV rays and high temperatures. Under the damage, the coating of the present invention is still sufficiently resistant to enthalpy, thereby ensuring the stability of electrical properties (these coatings maintain almost all of their resistivity). A curve in Figure 3 shows that the resistivity of the coating is greatly reduced when the coating is exposed to heat generated by the radiation. The coating contains only a coating formed by the interposition of high refractive index TiO SiO2 and is deposited on the reflector efficiency, including a 64-resistance computer. There are reflector natural condition layer reflection table A (3 1 5, UV test. If it is, it should measure the result, the upper, and thus the effect. Even if the storm can be maintained, that is, the UV rays appear forever 2 and low fold. On the inner surface -33- 200809133 (30), it is measured according to the above experimental procedure. As shown in "Figure 3", within about two seconds after the UV is turned on, the resistance 値 decreases by nearly three orders of magnitude (from approximately 2 The initial enthalpy of X 107 Ohms is reduced to 3 X 104 Ohms. If the electrodes of the two high-intensity bulbs are in contact with the coating, then when the resistivity is permanently reduced and reaches this order of magnitude, it is highly likely This creates a short circuit. Therefore, for today's smaller and smaller high-intensity luminaires, the existing and widely used coatings on the market do not fit φ as the best reflective optical coating. In addition, Figure 3 shows The second curve is relatively smooth. The curve is also composed of a high refractive index Ti〇2 and a low refractive index Si〇2 coating, but its composition is slightly different; when the ruthenium is not exposed to UV rays and high temperatures, it has Display order The unacceptable magnitude of the resistivity, after exposure to UV rays and high temperatures, has a further reduction in the resistivity.

The coating was made according to the design shown in Table 1, wherein the first part of the design comprises two layers, each of which is a layer formed by repeatedly interlacing a low refractive index material Si〇2 and a high refractive index material Ti〇2. The uppermost (last depositor) stack is composed of a high refractive index material coating that is resistant to UV rays and high temperature effects; in this example, it is formed by interlacing Ta2〇5 with g low refractive index material 8102. The coating was exposed to heat generated by UV rays and IR rays in accordance with the above experimental procedure. As noted above, the novelty of this design is that the coating thus produced and treated maintains substantially all of its resistivity, as shown in FIG. Essentially all of the resistivity values are: the amount of resistivity required to maintain the coating as an insulator; the electrodes placed in the coating can be brought into contact with the coating without concern for short circuits. If the two high-intensity bulb electrodes are in contact with the coating, the resistivity of the coating can be prevented from occurring even if exposed to UV rays and/or high temperature damage. Therefore, this coating is an excellent choice for use as a reflective optical coating in today's increasingly smaller high-intensity luminaires. -35- 200809133 (32) 1〇10

Figure 5 shows a coating made according to the design of Table 2, which has no substantial change in resistance 暴露 when exposed to heat generated by UV # ray and IR. In a comparative experiment to observe the effect of high temperature on the stability of the coating alone; a SiO 2 /Nb 205 coating prepared according to the design shown in Table 2 was deposited on the reflective inner surface of the glass substrate, and then the luminaire was Put in the oven' and heat to 1 〇〇〇 °C. After cooling, the coating was not subject to significant physical damage, but the glass showed significant signs of softening and deformation; in some experiments, the glass also cracked due to heat induced pressure. It should be noted that the coating remained adhered to the base of the deformed base -37-200809133 (34) and showed no signs of detachment from the substrate. This durability is not significant for reflectors made from conventional materials. Conclusion: In summary, the experimental results show that the optical coating produced in accordance with the design principles of the present invention is capable of controlling electromagnetic radiation as needed. That is, the coating of the present invention is designed to reflect and/or transmit the desired portion of the electromagnetic spectrum, in addition to providing better durability and reflectivity stability over the life of the luminaire. Unexpectedly and surprisingly against UV damage, it is even more surprising and surprising that the coating maintains its resistivity, making it more suitable for use in small, high-intensity luminaires. The operating temperature of the luminaire will also be higher. It should be understood that it is within the scope of the invention to deposit the coating, if desired, on the interior, exterior or both sides of the reflector. In particular, the coating exhibits resistance to UV rays and thermal degradation while delivering nearly all IR wavelengths (above 800 λ) and reflecting almost all visible light (400 - 700 λ).
