BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to underground lights, and more particularly, to underground lights that can express colored light of various patterns.

Recently, the landscape lighting device for lighting the exterior of the landscape facilities or buildings at night or to illuminate the sidewalks has been installed and used.

Underground lighting installed in the ground of the landscape lighting device is to be able to emit light by using a single or multi-color light source, but there is a disadvantage that can not change the lighting atmosphere variously.

In addition, even when it is possible to emit light of different colors, only the display color can be changed periodically, so that the display color change pattern due to regularity is monotonous.

The present invention has been made to improve the above problems, and an object thereof is to provide an underground lamp which can further diversify the color pattern displayed by a combination of different color lights.

It is still another object of the present invention to provide an underground lamp that can produce display light having a different pattern depending on the viewing angle.

In order to achieve the above object, the underground light according to the present invention has at least three or more reflecting plates having reflecting surfaces capable of reflecting incident light such that the reflecting surfaces are positioned inward so as to form a hollow polygonal space. Multiple reflectors; A light source module arranged so that a plurality of light emitting diodes emitting light of different colors may be arrayed to reflect light through the polygonal reflectors below the polygonal reflectors; And a cap installed on an upper portion of the polygon reflector to transmit light emitted through the polygon reflector so as to shield the polygon space of the polygon reflector to be shielded from the outside.

Preferably, the polygon reflector is formed such that at least one reflector extends longer than the other reflector.

The apparatus may further include a housing configured to accommodate the polygonal reflector and the light source module so as to be embedded in the ground, and the cap may be installed to close the inner space of the housing from an upper portion of the housing.

According to one aspect of the invention, the inner surface of the cap is formed with a plurality of projections spaced apart from each other to scatter the incident light.

More preferably, any one of the light source module and the polygon reflector is formed to be relatively rotated.

Hereinafter, the ground lamp according to the preferred embodiment of the present invention with reference to the accompanying drawings will be described in more detail.

1 is a cross-sectional view showing an underground light according to the present invention, Figure 2 is a perspective view showing a polygon reflector and a light source module installed in the housing of FIG.

1 and 2, the underground light 100 includes a housing 110, a cap 120, a polygon reflector 130, a light source module 140, and a driving motor 150.

The housing 110 has a structure having an inner space in which an upper portion is opened and a lower portion is closed.

The inner space of the housing 110 is formed to accommodate the polygon reflector 130, the light source module 140 and the driving motor 150.

In addition, the flange portion 114 that extends outward is formed above the body 112 of the housing 110.

The flange portion 114 is used for bonding when installed in a buried object, for example, the ground or other ground structure, or applied to suppress fluidity in a buried state.

The cap 120 is coupled to close the inner space at the upper portion of the housing 110 to protect the elements stored in the inner space and to transmit the light emitted through the polygon reflector 130 from the light source module 140. It is made of transparent or translucent material.

In the illustrated example, a structure in which the cap 120 is detachable by screwing the housing 110 is applied.

Unlike the illustrated example, the housing 110 may be omitted, and the cap may be coupled to the upper portion of the polygon reflector 130 to be constructed to shield the polygon space inside the polygon reflector to be shielded from the outside.

On the inner surface of the cap 120, a plurality of protrusions 122 for scattering the incident light is formed to be spaced apart from each other.

Unlike the illustrated example, the protrusion 122 may be omitted.

The polygon reflector 130 has three reflecting plates 131, 132, 133 having reflecting surfaces 131a, 132a, 133a capable of reflecting incident light to form a hollow polygonal space 130a. The reflective surfaces 131a, 132a, and 133a are bonded to each other so as to be positioned inside.

Preferably, the reflector 130 is formed such that one of the reflecting plates 133 extends longer than the other reflecting plates 131 and 132 so that the display color pattern may vary according to the viewing angle.

In the illustrated example, a structure in which the third reflector 133 extends longer than the first and second reflector plates 131 and 132 is illustrated.

In this case, the color patterns of different patterns may be provided depending on the viewing angle of the image pattern formed by the combination of various images via the polygon reflector 130.

Unlike the illustrated example, the polygonal reflector 130 may include four or more reflecting plates to be applied, such as a square and a five-corner.

The light source module 140 includes a plurality of light emitting diodes 141, 142, 143 that emit light of different colors from each other on the driving substrate 145.

Preferably, the light emitting diodes 141, 142 and 143 which emit red, green and blue light, respectively, are applied, and the number of applications of the light emitting diodes 141, 142 and 143 for each color is two or more. Of course it can.

The driving substrate 145 is configured to selectively drive or vary the driving duty of the light emitting diodes 141, 142 and 143 according to the set mode.

The light source module 140 emits light from the lower portion of the polygon reflector 130 through the polygonal space 130a, but reflects light through the reflecting plates 131, 132, 133 of the polygon reflector 130. It is preferable that the driving plate 145 be inclined so as to face the reflecting plates 131, 132, 133.

Preferably, one of the light source module 140 and the polygon reflector 130 may be relatively rotated to vary the display color pattern.

In the illustrated example, the driving motor 150 is installed to rotate the light source module 140 coupled through the rotation shaft.

Unlike the illustrated example, the light source module 140 may be constructed to be fixed in the housing 110 and to rotate the polygon reflector 130.

When the underground light 100 is installed for pedestrian or building landscape lighting, the polygon reflector 130 is changed whenever the relative position and direction of the pedestrian's underground light 100 in the process of passing the underground light 100 are changed. As the display pattern generated by the combination of various images generated while passing through is changed, it is possible to provide color light of a pattern that varies visually.

As described above, according to the underground light according to the present invention, various patterns of color patterns generated by the polygonal reflectors are provided differently according to positions and directions, thereby providing an advantage of illumination.
