Description

[0001] The present invention relates to a pattern replaceable LED lighting device,

The present invention relates to an LED landscape lighting apparatus, and more particularly, to a semi-permanent LED lighting apparatus capable of adjusting a variety of patterns and illuminations customized by a user, so that a variety of variable lights at night, The present invention relates to an LED lighting device capable of replacing a pattern that can reduce the manufacturing cost and manufacturing time of a product.

Generally, the bollard is installed in a road or a park for the boundary between the road and the road or for blocking the road entrance of the vehicle.

The bollard is mainly made of stone, so that the bollard is embedded and fixed at a certain depth on the ground of the road.

However, since the bollard is limited to the stone material, there is a limit to the visual design effect, and there is a disadvantage that the aesthetics of roads and parks are lowered.

In order to overcome these drawbacks, we have diversified the material of the bollard to improve the design. However, the roadbuilding facilities made of uniform design are suitable for various decorative themes and landscaping parks and roads. Was insufficient.

In addition, although the conventional bollard has a visual design effect with the light emitted from the bollard itself, there is a problem in that the function of illumination and guidance of roads and parks is insufficient.

In addition, in addition to the above-mentioned functions of the conventional bollard, research and development that can incorporate and utilize various functions by adding additional functions are required.

On the other hand, the landscape lighting facility is an illumination facility that focuses on various types of sculptures, statues of great figures, and outer surfaces of buildings to improve the landscape and design effects, and to attract the attention and interest of the general public.

In recent years, a large number of outdoor lighting facilities have been installed around a variety of sculptures using LEDs, thereby concentrating a plurality of landscape lighting on the sculptures.

However, there were also limitations in that it did not induce the interest of the general public because of the lack of landscape lighting facilities in places and facilities where various kinds of sculptures and artworks installed in parks and so on, and public places such as statues and cultural heritages of great people are noted.

Therefore, in order to overcome these limitations, it is necessary to attempt and study to improve visual landscaping and design effects in addition to merely dividing and alerting roads.

Meanwhile, a light emitting diode (LED) has a junction structure of a P-type and an N-type semiconductor, and when the voltage is applied, an optoelectronic element that emits light of energy corresponding to a band gap of a semiconductor by the combination of electrons and holes , The reaction time is faster than that of general bulbs, and the power consumption is as low as 20%, and recently it has been utilized in many fields including high efficiency lighting means.

The floodlight using such a light emitting diode utilizes a module in which a large number of high-brightness light emitting diodes or power LEDs are assembled on a substrate as a light source, and is used as a light source such as a signboard, a structure lighting, .

In addition, the illumination lamp using the light emitting diode may have a structure in which a plurality of light emitting diodes are disposed on a printed circuit board formed in a disk or various shapes so that the light emitting diode can be used as a general illumination lamp, a method in which a solid or flexible printed circuit And a line bar type method in which a plurality of light emitting diodes are arranged on a substrate at regular intervals.

In the former case, it is widely used in general illumination lamps and traffic lights. In the latter case, it is widely used in high-rise buildings, bridges, overpasses, and advertisements.

However, most of the conventional line-bar type LED lighting apparatuses have the same system in which the housing, which is a component thereof, is installed and fixed.

Further, since the pattern of the specific pattern is fixed to the outer periphery of the body of the lighting device, the design of the pattern can not be changed, the illuminating effect is reduced, and the limit of controlling various patterns and illuminance desired by the user is limited there was.
