Description

Manufacturing method of outdoor LED lighting device having anti-fog structure and outdoor LED lighting device manufactured thereby

The present invention relates to a manufacturing method of an outdoor LED lighting device having an anti-fog structure and an LED lighting device manufactured by the method, and more particularly, to airtightly seal an outdoor LED lighting device such as a LED traffic light or a LED display board, and to a light transmitting body. It relates to a manufacturing method of an LED lighting device having an anti-fogging structure capable of preventing fogging on the inner surface of a surface and an LED lighting device manufactured thereby.

Lighting devices are devices that convert electrical energy into light energy and emit light, and lighting devices having various types and functions are used throughout society, such as companies, homes, and roads. Such lighting devices have mainly used incandescent lamps, fluorescent lamps, halogen lamps, and mercury lamps as light sources.

Recently, an LED lighting device using an LED (hereinafter referred to as 'LED') element as a light source has been highlighted. This is because the LED lighting device has advantages such as a relatively long lifespan, low maintenance cost, and eco-friendly effect compared to lighting devices of other light sources.

Therefore, the demand for LED lighting devices is increasing exponentially, and in particular, demand for indoor lighting devices as well as outdoor lighting devices such as road traffic lights and streetlights, electronic signboards, building lighting, outdoor lighting and landscape lighting. It is also increasing significantly.

However, outdoor LED lighting devices that inevitably have to be exposed to environments such as snow or rain have a disadvantage in that they are very vulnerable to condensation.

That is, existing lighting devices using incandescent, fluorescent, halogen, and mercury lamps as light sources are basically kept in an airtight or vacuum state. Therefore, the problem caused by condensation is not greatly caused.

On the other hand, since the LED lighting device does not generate much heat due to the characteristics of the LED device when used, the low-temperature heat does not sufficiently dehumidify, so it is inevitably vulnerable to fogging or dew condensation.

Therefore, in the case of an LED lighting device installed as an outdoor lighting device, problems such as life shortening and failure frequently occur due to fogging or dew condensation. This is caused by the electronic characteristics of the LED, and in the case of the LED lighting device compared to other lighting devices, fogging or dew condensation is fatal. Of course, problems caused by fogging and condensation may be prevented by additionally embedding a dehumidifying member inside the LED lighting device, but in this case, the additional installation of the dehumidifying member inevitably causes an increase in manufacturing cost.

Therefore, it is necessary to propose an LED lighting device capable of reducing manufacturing costs by simplifying the overall structure while effectively preventing fogging and condensation.

In addition, in the charging step (S600), it is preferable that the space between the front side of the LED lighting module and the opposite surface side of the transparent housing has an internal pressure such that the pressure is equalized with the external air pressure.

In other words, in the filling step (S600), in filling the inert gas, the filling pressure is adjusted while filling to have a pressure corresponding to or close to atmospheric pressure, or a pressure adjusting process is performed after filling.

In this way, the inert gas is filled in the space between the front side of the LED lighting module and the opposite surface side of the transparent housing through the charging step (S600), and the pressure in the space is parallel to the external pressure (atmospheric pressure). It is possible to reliably block the flow of air between the inner space and the outside.

Next, in the lighting device completion step (S700), after passing through the inert gas filling step (S600), the rear portion of the LED lighting module and the open portion of the transparent housing are molded with a molding material such as epoxy to externally ( Atmospheric pressure), the space between the front side of the LED lighting module filled with inert gas and the opposite surface side of the transparent housing is more reliably hermetically sealed.

A mountable coupling portion (second mounting coupling portion) may be formed.

Here, in the printed circuit board 200 of the LED lighting module 200, before the inert gas is filled in the space between the front side of the LED lighting module 200 and the opposite surface side of the transparent housing 100, that Holes 221 and 222 used to evacuate the space and fill the inert gas are formed.

Here, all or at least one of the holes may be formed on the transparent housing 100 instead of the printed circuit board 220 of the LED lighting module 200 . However, in the present invention, when considering manufacturability or airtightness of an outdoor LED lighting device, it is preferable that the holes 221 and 222 are formed on the printed circuit board 220 of the LED lighting module 200.

Continuing, the sealing member is the edge of the printed circuit board 220 of the LED light module 200 and the transparent accommodation housing 100 in a state of being accommodated and mounted in the transparent accommodation housing 100 in the LED lighting module 200. ), and the lead-out hole (or lead-out path) of the cable connected to control the LED lighting module 200 may be formed by sealing with epoxy resin or the like.

This sealing member not only prevents external foreign substances from penetrating into the interior of the LED lighting device, that is, the space between the front side of the LED lighting module 200 and the opposite surface side of the transparent housing 100, but also prevents the LED lighting module (200 ) It is an essential component provided to charge the inert gas after vacuuming the space between the front side of the transparent housing 100 and the opposite surface side of the transparent housing 100.

Next, the inert gas is preferably nitrogen or argon, and these nitrogen or argon can also provide a function as a coolant while being an inert gas.

In addition, the inert gas may be used as an inert gas such as nitrogen or argon, as well as an inert gas selected in consideration of mass and weight according to the structure, purpose of use, or application of the LED lighting module.
