The present invention relates to a method of manufacturing an outdoor LED lamp for assisting the dimming control, and more specifically, to a configuration of a controller or a control unit for the conventional LED dimming control, including a fluorescent material and a phosphor in the case of the LED lamp By applying a light-emitting coating layer to assist the LED dimming control can reduce the electrical consumption for light emission can reduce the cost, aesthetics can also be improved, and the visibility is improved because the light is maintained for a certain period of time The present invention relates to a manufacturing method of an outdoor LED lighting lamp to assist dimming control.

First, dimming means adjusting illumination (brightness). At this time, the dimming control method is a DALI system, a European standard protocol dimming method, a DC system used for dimming mainly an LED point for T5 (fluorescent lamp), a TE / LE system with a 220V phase control method, an outdoor street lamp and a parking lot. There is an intelligent wireless dimming system, which is a wireless dimming control system. Such dimming can produce a variety of lighting according to the user's needs and preferences, there is an effect that the energy saving effect can be maximized.

At this time, when a plurality of LED lamps are installed at a predetermined interval along the length of the tunnel, particularly in the interior of the tunnel, the amount of light exposed to the LED lamps decreases while moving from the entrance to the inside. As the amount of light exposed to the LED lamp increases as it moves toward the exit side, differential dimming control is required accordingly. For the differential dimming control, the entrance of the controller and the controller of the controller that performs the dimming control function are basically used. The technique of grasping the amount of light or luminance at the exit side and differentially performing dimming control for each specific area in the tunnel has been developed.

Korean Patent No. 10-1381941 (name of the invention: LED dimming control system and method) is published as a prior art related to differential dimming control for each specific area such as the entrance / exit of a tunnel.

And the two representative external luminance values corresponding to the two representative external luminance values according to the ratio of the two representative external luminance values and the current external luminance value by applying the two representative external luminance values and the dimming values such as the two tunnels. A control unit for dividing a network value and calculating a dimming value such as a current tunnel corresponding to the current external luminance value; And a dimming control unit configured to adjust illuminance of the LED tunnel lamp in response to the dimming value of the current tunnel lamp, wherein the representative external luminance value stored in the storage unit and the tunnel lamp dimming value corresponding to the representative external luminance value are discrete. Dimming control system, such as LED tunnel, characterized in that the value is proposed.

According to the above prior art, in the conventional dimming control method, a more detailed and precise differential dimming control can be made by using discrete values, but a process of obtaining a result value using discrete values for dimming control is possible. Not only can it be complicated, but it also has the disadvantage of having to install a plurality of luminance sensors in order to obtain luminance values for each region.

In this case, in the present invention, in addition to the configuration for the conventional LED dimming control described above, the main feature is to assist the LED dimming control by applying a light emitting coating layer containing a fluorescent material and a phosphor to a case of the LED lamp surrounding the LED element. .

When the dimming control is assisted in this way, when the light is received when the sunlight is not too strong, such as at the entrance or exit of the tunnel, or at dawn or at sunset, the light is emitted for a predetermined time by a case such as an LED lamp coated with phosphor and phosphor. It can hold and emit light. Through this phenomenon, it is possible to reduce electrical consumption for light emission, thereby reducing costs, improving aesthetics, and improving visibility by maintaining light for a certain period of time, thereby preventing accidents.

At this time, the auxiliary of the dimming control corresponds to the existing dimming even if the dimming control is performed to emit a light amount slightly lower than that required for the existing dimming by maintaining the existing dimming control method so that the LED light can be stored for a relatively long time. Means to achieve a control function. To this end, the present invention assists such dimming control through the specific properties of the case of the LED lamp, such a dimming aid can reduce the loss of electrical energy by the photoluminescent performance is economical and not complicated compared to the electrical / electronic control method It can provide the advantage of being easy without.

That is, the present invention does not replace the configuration for the known dimming control but may be added to the configuration for the known dimming control. In this case, the configuration for the known dimming control may include a communication unit performing communication with the outside of the tunnel; The dimming control unit for differentially adjusting the amount of light of the LED lamp according to the luminance sensor for measuring the luminance of the tunnel, the luminance value detected by the luminance sensor, in other words, the present invention has a known dimming control configuration By having an additional configuration to be described later, the additional configuration to be described later to assist the dimming control of the LED lamp.

In addition, in the present invention, the outdoor is a concept that encompasses various places where LED lights can be generally installed, such as a park or a street, but is not limited to a specific place but is particularly useful when installed in a tunnel. It is assumed that a plurality of tunnels are installed at regular intervals.

 1 is a flowchart illustrating a method of manufacturing an LED lamp of the present invention, the method of manufacturing an LED lamp of the present invention may include a first step (S100), a second step (S200), a third step (S300). have.

First, the first step (S100) is a process of preparing an LED module made of a substrate on which the LED device is mounted. Here, the LED element serves as a light source of the LED lamp, the material of the substrate may be PCT, glass fiber, and the like, may have a rectangular, circular shape, without particular limitations on this. In this case, the LED device has a long life, has a low maintenance cost, and has an advantage of superior light efficiency than a fluorescent lamp or an incandescent lamp.

Next, the second step (S200) is a process of preparing a case in which a light emitting coating layer containing a phosphor and a fluorescent material is laminated, and the third step (S300) is to install the case so as to face the LED device to install an LED lamp It's a process of completion.

Here, the case is to enclose the above-described LED module, the shape is not limited if it can wrap and protect the LED device well in accordance with the size of the LED substrate. At this time, since the case should emit the light of the LED element to the outside, it is preferable to have a transparent to translucent property.

In addition, the light emitting coating layer includes a phosphor and a fluorescent material, and fluorescence refers to a phenomenon in which a material emits light by stimulation of light, and a material receiving energy emits new light, which is different from reflection. . In addition, phosphorescence refers to a phenomenon that emits light for a long time even after removing light from an object, or means the light, and when visible light is stimulated from the outside such as electron beam, radiation, ultraviolet ray, and short wavelength visible light, Release. In this case, phosphorescence emits light for a longer time than fluorescence because the electrons in the material do not go directly to the ground state in the excited state, but lose energy through the metastable state in the middle.

In another embodiment, an antireflective coating solution including a titanium compound and tetraethyl orthosilicate is applied to the surface of the light emitting coating layer and then heat treated at 100 to 140 ° C. for 5 to 30 minutes to form an antireflective coating layer. Can be. That is, the anti-reflective coating layer may be additionally laminated on the light emitting coating layer, thereby preventing the phenomenon in which light or illumination is reflected by the case and the luminous effect of the phosphor and the fluorescent material is inferior, and thus the light emitting laminated on the LED lamp. The visibility by the coating layer can be maximized.

Figure 2 is a flow chart showing a process for producing an anti-reflective coating solution of the present invention, the process for producing such an anti-reflective coating liquid is specifically prepared material preparation step (S230), preparation solution preparation step (S231), anti-reflective coating solution manufacturing step It may include (S232).

First, the preparation material preparing step (S230) is a process of preparing a preparation material by mixing 50 to 75% by weight of the titanium compound and 25 to 50% by weight of tetraethyl orthosilicate based on the total preparation material weight. Both the compound and the tetraethyl orthosilicate are materials having low light reflectance, and both materials are used as the active ingredient instead of only one of them as the active ingredient, thereby improving the light reflectance lowering function of the antireflective coating liquid. In particular, tetraethyl orthosilicate has transparency, even if the anti-reflection coating layer is formed on the surface of the LED lamp case can maintain the light efficiency of the LED lamp as it is.

Then, the preparation solution preparation step (S231) is 0.1 to 10% by weight of ammonium hydroxide (NH ₄ OH), 20 to 35% by weight of water, 60 to 75% by weight of ethanol at 10 to 50 to 70 ℃ relative to the total weight of the preparation solution A process of preparing a preparation solution by stirring for 60 minutes, wherein the preparation solution serves to form a sol-gel solution by mixing with the preparation material described above. That is, since the spherical nanoparticles of the titanium compound and tetraethyl orthosilicate are prepared by ammonium hydroxide and ethanol, a homogeneous antireflective coating liquid can be prepared.

Next, the anti-reflective coating solution manufacturing step (S232) is a 25 to 40% by weight of the preparation material and 60 to 75% by weight of the preparation solution relative to the total weight of the anti-reflective coating solution by stirring at 60 to 80 ℃ for 10 to 30 hours As a process for preparing a, it is a step of preparing an anti-reflective coating liquid of the sol-gel shape by mixing the preparation material and the preparation solution. At this time, by preparing the anti-reflective coating solution in the form of a sol-gel, nano particles (which are titanium-based compounds and tetraethyl orthosilicate particles) that perform anti-reflection functions are formed and are homogeneously when applied to the surface of the LED lamp case. Applied to ensure that the antireflective effect is evenly distributed.

Thereafter, the step of forming an antireflective coating layer may be performed, which allows the antireflective coating liquid to be thinly and evenly coated on the light emitting coating layer by spraying to maintain light efficiency of the LED lamp and at the same time reduce light reflectance. It is a step of forming an anti-reflective coating layer to perform the function.

The anti-reflective coating layer formed through the above process prevents a phenomenon in which the luminous efficiency of the phosphor and the fluorescent material is reduced when light or illumination is reflected, thereby providing a function of improving visibility of the LED lamp of the present invention.

At this time, the anti-reflective coating solution forming the anti-reflective coating layer is a titanium compound and tetraethyl orthosilicate as an active ingredient, the titanium compound may be titanium dioxide (TiO ₂ ) or titanium isopropoxide (Titanium isopropoxide). .

At this time, titanium dioxide is very oxidizing power and is activated as a photocatalyst when UV light is exposed, which may damage phosphors and fluorescent materials and reduce the color clarity. Therefore, it is desirable to form an aluminum coating layer having excellent stability and durability on the surface of the titanium dioxide particles to suppress photocatalytic activity of titanium dioxide.

To this end, the process of preparing the titanium compound may include an initial solution preparation step, an intermediate solution preparation step, a pH adjustment step, a precipitate obtaining step, and a drying step.

First, the initial solution preparation step is a process for preparing an initial solution by mixing 10 to 50% by weight of titanium dioxide and 50 to 90% by weight of water relative to the total initial solution weight, preparing a titanium dioxide aqueous solution to prepare a titanium compound It's a step.

Next, the intermediate solution preparation step is a process of preparing an intermediate solution by dropping the aluminum chloride aqueous solution in the initial solution for 1 to 3 hours, which is to form an aluminum coating layer on the surface of the titanium dioxide particles contained in the initial solution. .

At this time, preferably, the aluminum chloride solution is dropped in the initial solution so that the aluminum chloride solution is 50 to 60% by weight based on the total weight of the intermediate solution so that the aluminum coating layer is uniformly and thinly formed on the surface of the titanium dioxide particles.

The aluminum coating layer protects the titanium dioxide particles and at the same time prevents photolysis of titanium dioxide, thereby providing a function of improving the durability of titanium-based compound titanium dioxide.

Thereafter, the pH adjusting step is a process of adding a pH adjusting agent so that the pH of the intermediate solution is 7-9, wherein the pH adjusting agent may be ammonia water or sodium hydroxide, and preferably, the pH adjusting agent is added so that the pH is 8-9. It is suitable to form an aluminum coating layer on the surface of the titanium dioxide particles.

Next, the step of obtaining a precipitate is a process of obtaining a precipitate formed by aging a pH-controlled intermediate solution for 1 to 3 hours, wherein the precipitate includes titanium dioxide particles having an aluminum coating layer as a white solid.

Finally, the drying step is a process of drying the residue obtained by washing the precipitate after filtration and drying it at 50 to 70 ° C. for 10 to 15 hours.

At this time, the precipitate may be washed 1 to 5 times with distilled water to remove aluminum chloride and titanium dioxide particles not involved in forming the aluminum coating layer.Titanium dioxide having an aluminum coating layer is formed by removing distilled water used for washing through filtration. Titanium compounds can be obtained.

Such a titanium compound may not only lower the light reflectance but also enhance the durability of the antireflective coating layer through titanium dioxide (that is, the titanium compound produced through the above process) in which an aluminum coating layer is formed.

As described so far, a method of manufacturing an outdoor LED lamp for assisting dimming control according to the present invention has been represented in the above description and the drawings, but this is merely an example, and the spirit of the present invention is not limited to the above description and the drawings. Of course, various changes and modifications are possible without departing from the spirit of the present invention.
