Description

LED lighting device and its control method {LED LIGHTING APPARATUS AND CONTROL METHOD OF THE SAME}

The present invention relates to an LED lighting device and a control method thereof.

Recently, many lighting apparatuses using light emitting diodes (LEDs) have been developed.

Such LED lighting devices are widely applied to indoor and outdoor space lighting of buildings such as indoor lamps and table lamps, and lighting using light guide plates is further developed.

Since the LED lighting device has high photoelectric conversion efficiency, power consumption is low, and since it is not thermally discharged light, there is an advantage in that the lighting and extinguishing speed are unnecessary because no preheating time is required. In addition, the LED lighting device has no gas or filament, so it is strong and safe against shocks, and the stable DC lighting method is used to reduce power consumption, repeat and pulse operation, reduce optic nerve fatigue, and have a long service life. In addition, the lighting effect of various colors can be produced, and the use of a small light source has the advantage of miniaturization.

On the other hand, the LED module used in the general LED lighting device has a simple structure so that water or moisture can penetrate between the mating surfaces, and when the intruded water or moisture is left for a long time, the LED module is provided through a gap. Is introduced into the interior of the problem that acts as a cause of corrosion.

In order to solve the problem of such an LED module, a technology such as Patent Document 1 has been proposed.

The technology of Patent Document 1 forms a drainage path along the top, bottom, left and right sides of the LED module, and attaches the first waterproof member and the second waterproof member to the joint portion of the panel to improve the waterproof function. "Cover".

However, even in the case of Patent Document 1, although the drainage path is formed, the water or moisture introduced into the drainage path is left for a long time without being naturally discharged because the drainage path does not have an inclination, thereby corroding the surface of the LED module. It was insufficient to solve the problem, and was inadequate in terms of cost, such as the need to include a waterproof member separately.

In addition, an electronic signboard or an electronic signboard is typically a system for displaying various types of information in a visible still or moving state. Such an electronic signboard is widely used for commercials, stadiums, multi-visions, traffic signals, information and messages, or arts, and its size and application system may vary depending on the application, object, or location.

In particular, when using the LED lighting device for art, it consists of a LED module, a LED driving device and a control device for controlling the LED driving device connected to a plurality of LEDs.

However, the LED lighting device can be controlled only by factors such as the arrangement form of the LED module or the operation of the driving device. Therefore, the pattern of the output LED light is one-time and difficult to store and reproduce. It was.

Therefore, there is a need for a technique for solving the above-mentioned corrosion problem of the LED lighting device in a structural manner and additionally controlling and storing light output from the LED according to an external environment so that a beautiful lighting expression can be repeatedly implemented. There is a great demand.
