Description

Technical Field

[0001] The invention relates to an anti-fog warning lamp, in particular to a flat-type vehicle anti-fog warning lamp, and a method for preparing the flat-type vehicle anti-fog warning lamp. Background Art

[0002] In the automobile lighting system, fog lights are a very important signal light, mainly used for road lighting and warning when driving in rainy and foggy weather. Anti-fog lights generally use yellow as the main color, which has strong penetrating ability in rainy and foggy environments. Yellow light is the best choice made by scientists after careful research. The light of the fog lamp must have a scattering effect so that the light beam can dissipate heat forward as much as possible to form a large area beam, so that oncoming drivers can see the target clearly and the drivers behind can see their own vehicles. The scattering intensity of yellow light is 5 times that of red light. Obviously, using yellow light as the light color of automobile fog lights is much more efficient than using red light. There is another reason. The yellow light beam is not as dazzling as other colors of light beams, so it will not hinder the passage of other vehicles.

[0003] At present, the light sources of anti-fog lamps used in cars generally include incandescent lamps, halogen lamps and LED light sources. Although these lamps can emit yellow light beams, due to the influence of the lamp structure, the wavelengths of the light beams are not the same, and the relative ability to penetrate fog is also different, so the anti-fog effect is also different.

[0004] In response to this phenomenon, industry insiders have conducted in-depth research on the penetration wavelength of light beams, hoping to find out which range of emission wavelengths is the best wavelength for penetrating fog. There is an article numbered: 1002-2082 (2008) 04-0530-03, a paper titled "Experimental Determination of the Optimal Wavelength for Fog Light Penetration Ability", which concluded that the ability of light beams with a wavelength in the range of 570nm-590nm to penetrate fog is optimal, and a light beam with a wavelength of 578nm is the best penetration wavelength. However, it is difficult for existing incandescent lamps, halogen lamps and LED light sources to meet the above requirements, especially light beams with a wavelength controlled at 578nm. Therefore, it is an urgent need to develop a flat anti-fog warning light with an emission wavelength in the best penetration wavelength range. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a flat-type vehicle anti-fog warning light whose penetration wavelength can be controlled in the range of 570nm-590nm.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a flat-type vehicle anti-fog warning light, the innovation of which is: comprising:

[0007] A warning light body, wherein the warning light body is a hollow closed structure formed by connecting a front substrate glass, a rear substrate glass and a support, and the inner cavity of the warning light body is filled with neon gas, and the pressure of the neon gas is between 380-450 torr;

[0008] An electrode assembly is also arranged on the side of the rear substrate glass close to the front substrate glass, and the electrode assembly includes an odd electrode group and an even electrode group, wherein the odd electrode group is composed of a plurality of odd electrodes, and the even electrode group is composed of a plurality of even electrodes, and the odd electrodes and the even electrodes are spaced apart. An insulating medium layer covering the entire electrode assembly is also arranged on the rear substrate glass, and the odd electrodes and the even electrodes are respectively loaded with voltages of the same amplitude and opposite phases.

[0009] Furthermore, a silicon dioxide film or a titanium dioxide film is provided on a side of the front substrate away from the rear substrate glass.

[0010] Furthermore, the refractive index of the silicon dioxide film or titanium dioxide film is between 1.67-1.85, and the thickness is between 5nm-5.5nm.

[0011] Furthermore, the voltage of the odd-numbered electrodes and the even-numbered electrodes is between ±100-±200V.

[0014] S2: taking a substrate glass as a rear substrate glass, using a cleaning machine to clean the rear substrate glass with deionized water, and after cleaning, punching exhaust holes on the rear substrate glass;

[0015] S3: Ag electrodes are prepared on the side of the rear substrate glass by screen printing technology to form odd electrodes and even electrodes. The odd electrodes and even electrodes constitute an odd electrode group and an even electrode group respectively. Then, voltages with the same amplitude and opposite phases are applied to the odd electrodes and the even electrodes respectively. The voltage values ​​of the odd electrodes and the even electrodes are between ±100-±200V.

[0016] S4: forming an insulating dielectric layer covering all the Ag electrodes on the rear substrate glass by laminating or applying glue, and the Ag electrodes extend out of the insulating dielectric layer on a side away from the rear substrate glass;

[0017] S5: taking another substrate glass as the front substrate glass, and using a cleaning machine to clean the front substrate glass with deionized water;

[0018] S6: placing a support between the front substrate glass and the rear substrate glass, and then using low melting point glass to seal and connect the front substrate glass, the rear substrate glass, and the support to form a whole, thereby forming a semi-finished anti-fog warning lamp;

[0019] S7: vacuuming the semi-finished anti-fog warning lamp from the exhaust hole of the rear substrate glass, so that the vacuum degree in the inner cavity of the semi-finished anti-fog warning lamp reaches 10 -3 Finally, neon gas is filled into the inner cavity of the semi-finished anti-fog warning lamp from the vent hole until the pressure of the neon gas reaches between 380-450 torr to form a finished anti-fog warning lamp, thus completing the preparation of the anti-fog warning lamp.

[0020] Furthermore, in step S4, the insulating dielectric layer is preferably an aluminum oxide film.

[0021] Furthermore, in the step S5, after the front substrate glass is cleaned, a silicon dioxide film is preliminarily coated on the side surface of the front substrate glass.

[0024] The voltage is designed to be controlled between ±100-±200V, firstly to ensure that the warning light can light up smoothly, and secondly to avoid the phenomenon of scorching or burning of the substrate glass and circuit due to excessive voltage.

[0025] In addition, the entire anti-fog warning light adopts a shell structure formed by the front substrate glass, the rear substrate glass and the support, thereby forming a planar structure. Compared with the traditional downlight structure, it is easy to install and suitable for placement around large vehicles and engineering vehicles.

[0026] Through the preparation method of the present invention, an anti-fog warning light with a light beam penetration wavelength in the range of 570-590nm can be prepared, and then through the combination of a silicon dioxide film, the penetration wavelength can be stabilized at 578nm, having the best ability to penetrate fog, and is suitable for being placed around large vehicles and engineering vehicles to meet the needs of large vehicles and engineering vehicles.

[0030] The following embodiments can enable those skilled in the art to more fully understand the present invention, but the present invention is not limited to the scope of the embodiments.

[0031] like Figure 1 , Figure 2 A flat-type vehicle anti-fog warning light is shown, comprising

[0032] A warning light body, which is a hollow closed structure formed by connecting a front substrate glass 1, a rear substrate glass 2 and a support 3. In this embodiment, the warning light body has two structural forms:

[0033] The first structure of the warning light body is: the front substrate glass 1 and the rear substrate glass 2 are both rectangular glass plates, there are four supports 3, each of which is a rectangular plate. In this structural state, the warning light body formed by the supports 3 and the front substrate glass 1 and the rear substrate glass 2 connected together is a hollow rectangular structure.

[0034] The second structure of the warning light body is: the front substrate glass 1 and the rear substrate glass 2 are both circular glass plates, and there is one support 3, which is an annular plate. In this structural state, the warning light body formed by the support 3 and the front substrate glass 1 and the rear substrate glass 2 connected together is a hollow cylindrical structure.

[0035] The inner cavity of the warning light body is filled with neon gas, and the pressure of the neon gas is between 380-450 torr.

[0036] An electrode assembly is also provided on the side of the rear substrate glass 2 close to the front substrate glass 1, and the electrode assembly includes an odd electrode group and an even electrode group, wherein the odd electrode group is composed of a plurality of odd electrodes 4, and the even electrode group is composed of a plurality of even electrodes 5, and the odd electrodes 4 and the even electrodes 5 are spaced apart. An insulating medium layer 6 covering the entire electrode assembly is also provided on the rear substrate glass 2, and the insulating medium layer 6 is preferably an aluminum oxide film.

[0037] The odd-numbered electrodes 4 and the even-numbered electrodes 5 are respectively loaded with voltages of the same amplitude and opposite phases, and the voltages of the odd-numbered electrodes 4 and the even-numbered electrodes 5 are between ±100-±200 V. The voltage is designed to be controlled between ±100-±200 V, firstly to ensure that the warning light can light up smoothly, when the voltage is lower than ±100 V, the neon gas cannot light up normally, and secondly to avoid the phenomenon of the substrate glass and the circuit being scorched or burned due to excessive voltage.

[0038] A silicon dioxide film 6 is also provided on the side of the front substrate glass 1 away from the rear substrate glass 2. By covering the front substrate glass 1 with the silicon dioxide film 6, the passing light beam can be filtered, so that the penetration wavelength can be stabilized or tend to be stabilized at a value of 578nm, ensuring the best fog penetration. Figure 2 shown.

[0039] The refractive index of the silicon dioxide film 6 is between 1.67-1.85, and the thickness is between 5nm-5.5nm. The design of the refractive index and thickness parameters of the silicon dioxide film 6 can be matched with neon gas of different pressures to ensure that the optimal penetration wavelength can be stabilized at 578nm to achieve the best penetration effect.

[0040] The flat-type vehicle anti-fog warning light of the present invention is filled with neon gas and the pressure of the neon gas is controlled between 380-450torr, and voltages with the same amplitude and opposite phase are loaded, so that the warning light can generate a light beam with a wavelength in the range of 570-590nm, so as to achieve good fog penetration.

[0041] The method for preparing the flat-type vehicle anti-fog warning lamp of the present invention is specifically implemented by the following steps:

[0042] S1: First, prepare the materials required for preparing the anti-fog warning lamp, which includes a front substrate glass, a rear substrate glass, a support, odd-numbered electrodes, even-numbered electrodes, and an insulating dielectric layer.

[0043] S2: A substrate glass is taken as a rear substrate glass, and the rear substrate glass is cleaned by a cleaning machine using deionized water, and after cleaning, an exhaust hole is punched on the rear substrate glass.

[0044] S3: Ag electrodes are prepared on the side of the rear substrate glass by screen printing technology to form odd electrodes and even electrodes. The odd electrodes and even electrodes constitute odd electrode groups and even electrode groups respectively. Then, voltages with the same amplitude and opposite phases are applied to the odd electrodes and even electrodes respectively. The voltage values ​​of the odd electrodes and even electrodes are between ±100-±200V.

[0045] S4: forming an insulating dielectric layer covering all the Ag electrodes on the rear substrate glass by laminating or applying glue, and the Ag electrodes extend out of the insulating dielectric layer on the side away from the rear substrate glass. The insulating dielectric layer is preferably an aluminum oxide film.

[0046] S5: taking another substrate glass as the front substrate glass, and using a cleaning machine to clean the front substrate glass with deionized water. After the front substrate glass is cleaned, a silicon dioxide film is preliminarily coated on the side of the front substrate glass.

[0047] S6: placing a support between the front substrate glass and the rear substrate glass, and then using low-melting-point glass to package and connect the front substrate glass, the rear substrate glass, and the support to form a whole, thereby forming an anti-fog warning lamp semi-finished product.

[0048] S7: vacuuming the semi-finished anti-fog warning lamp from the exhaust hole of the rear substrate glass, so that the vacuum degree in the inner cavity of the semi-finished anti-fog warning lamp reaches 10 -3 Finally, neon gas is filled into the inner cavity of the semi-finished anti-fog warning lamp from the vent hole until the pressure of the neon gas reaches between 380-450 torr to form a finished anti-fog warning lamp, thus completing the preparation of the anti-fog warning lamp.

[0052] Table 2 is a comparison of different penetration wavelengths of warning lights prepared by the above preparation method under the same voltage, with and without silicon dioxide film attached. Example 8 is a warning light with silicon dioxide film attached, and Example 9 is a warning light without silicon dioxide film attached:

[0054] Table 2

[0055] Table 3 is a comparison of the penetration wavelengths of the anti-fog warning lamp prepared by the method of the present invention and the conventional anti-fog warning lamp. Examples 10 to 12 are three different incandescent lamps, Examples 13 to 15 are three different halogen lamps, Examples 16 to 18 are three different LED lamps, and Examples 19 to 21 are three warning lamps manufactured by the present invention:

[0056] Transmission wavelength Peak half-width Incandescent lamp Embodiment 10 568nm 82nm Embodiment 11 566nm 81nm Embodiment 12 568nm 82nm Halogen lamp Embodiment 13 572nm 48nm Embodiment 14 568nm 47nm Embodiment 15 567nm 47nm LED Light Embodiment 16 566nm 60nm Embodiment 17 567nm 61nm Embodiment 18 569nm 62nm Warning light of the present invention Embodiment 19 575nm 20nm Embodiment 20 578nm 15nm Embodiment 21 582nm 25nm

[0057] Table 3

[0058] It can be seen from the data in Table 1 that when voltage is applied to odd-numbered electrodes and even-numbered electrodes, when the loaded voltage value is lower than ±100V, the warning light is off. When the loaded voltage value is higher than ±200V, although the penetration wavelength can be maintained between 570nm-590nm, the warning light will be burnt after a period of use. Moreover, the higher the voltage value, the longer the burnt phenomenon will occur. The warning light is optimal only when the loaded voltage value is between ±100V-±200V.

[0059] It can be seen from the data in Table 2 that, for the warning light with silicon dioxide film, when the loading voltage changes, the penetration wavelength can still be well maintained at 578nm or tend to 578nm, while for the warning light without silicon dioxide film, when the loading voltage changes, the penetration wavelength will have obvious ups and downs, and can only be maintained in the range of 570-590nm, and it is difficult to reach 578nm.

[0060] It can be seen from the data in Table 3 that the penetration wavelength of the warning light prepared by the preparation method of the present invention can be stabilized in the range of 570-590nm, while the penetration wavelengths of traditional incandescent lamps, halogen lamps, and LED lamps cannot achieve this purpose. Even if there are lamps that can reach the range of 570-590nm, the value of the peak half-width will be relatively high. The lower the value of the peak half-width, the purer the yellow, the better the monochromaticity, and the higher the transmittance. Otherwise, it cannot meet the requirements.

[0061] Through the preparation method of the present invention, an anti-fog warning light with a light beam penetration wavelength in the range of 570-590nm can be prepared, and then through the combination of a silicon dioxide film, the penetration wavelength can be stabilized at 578nm, having the best ability to penetrate fog, and is suitable for being placed around large vehicles and engineering vehicles to meet the needs of large vehicles and engineering vehicles.

[0062] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
