The present invention relates to an indirectly lit street light that reflects illumination light and provides indirect illumination, and relates to an indirectly lit street light that attenuates the illuminance of the reflected reflected light to provide indirect illumination.

In general, street lamps emerge as direct lighting that emits light directly on the ground and indirect lighting that emits light indirectly on the ground by reflecting the light. Such direct-lighted streetlights typically have their lamps exposed directly to the ground. In addition, the indirect lighting street lamp is concealed from the outside as the lamp is built in the column.

As shown in FIG. 1, the indirectly lit street light is indirectly provided to the ground after the illumination light of the lamp 2 is projected upward and reflected by the reflecting plate 4 of the lampshade 3 installed at the upper end of the column 1. do. At this time, the illumination light of the lamp 2 is slightly attenuated by the reflector 4. Thus, indirectly lit street lamps as shown provide soft lighting to the ground.

Since the indirect lighting street light is blocked by the lampshade (3) to prevent the illumination light is projected upward. Accordingly, the indirect lighting streetlight does not transmit the illumination light to the second floor of the building located around. Therefore, people living on the second floor of the surrounding building are not disturbed by the lighting. That is, indirect lighting street lamps do not cause sleep disturbances of people living on the second floor.

However, the indirectly-illuminated street lamp as described above is too bright because the reflecting plate 4 specularly reflects the illumination light of the lamp 2 directly in effect. Accordingly, a general indirectly illuminated street lamp provides excessive illumination to plants located under the lampshade 3, ie located around the street lamp. Therefore, the general indirect lighting streetlight has a problem that hinders the growth of plants located around the streetlight. In other words, the plants located in the vicinity of the indirect lighting street lamps are reduced in growth due to sleep disturbance caused by the illumination light.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and is provided with a member for scattering a part of the illumination light projected on the reflector to provide an indirectly lit street light that can attenuate the luminance of the illumination light and enter the reflector. This is the purpose.

Another object of the present invention is to provide an indirect-illuminated street lamp having a mechanism for easily fixing a member that scatters a part of the illumination light to the lampshade.

In addition, another object of the present invention is to provide an indirectly-illuminated street lamp having a structure capable of diffusely reflecting illumination light on a member that scatters a part of the illumination light.

In addition, the illumination light incident to the center portion of the lampshade is reflected while being diffused in a declination state, the illumination light incident to the outside of the center portion of the lampshade is another object to provide an indirect lighting street lamp that is substantially specular reflection.

Indirect lighting street light according to the present invention for achieving the above object is a light source for irradiating the illumination light to the top; A column in which the light source is embedded in an upper end portion; A plurality of poles fixed in a vertical state at equal intervals along the upper edge of the column; A lampshade horizontally installed at an upper end of the pole to face the light source while being closed to close the top of the column; A fixing member integrally fixing the lampshade to the pole; A reflection plate installed under the lampshade fixed to the pole by the fixing member and reflecting the illumination light of the light source irradiated to the lower surface of the lampshade to the opposite side to provide indirect illumination to the lower part of the column; A light transmitting plate disposed below the reflecting plate and transmitting a portion of the illumination light emitted from the light source to the reflecting plate to attenuate illuminance of the illumination light; And a coupling means for integrally coupling the floodlight plate and the reflection plate to the lower portion of the lampshade.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 2 is a side view showing the configuration of an indirectly lit street light according to an embodiment of the present invention in a half section.

As shown, the indirect lighting street lamp according to an embodiment of the present invention is a light source (50); Column 60; Pole pole 70; Lampshade 82; A reflector plate 84; It includes; a transparent plate (86). The following describes these components in more detail.

First, the light source 50 described above is embedded in the upper end of the column 60 as shown. This light source 50 includes a lamp 52 for emitting illumination as shown; A reflection shade 54 provided on the main surface of the lamp 52; And a transparent plate 56 installed on the reflection shade 54. Of course, the light source 50 may be composed of only the lamp 52, alternatively, may be composed of the lamp 52 and the reflector 54. That is, the light source 50 may omit at least one of the reflection shade 54 or the transparent plate 56.

Next, the column 60 described above is a hollow steel pipe as shown. The column 60 may be installed by bolting or welding the horizontal plate 62 on the upper end so that the pole 70 to be described later is installed as shown. That is, the pole 70 is provided on the horizontal plate 62.

Such a column 60 is irradiated with illumination light to the upper portion as the light source 50 is built in the upper end. That is, the light source 50 transmits the illumination light to the upper portion of the column 60.

Next, the pole pole 70 is configured as shown in the plurality of as shown in the equal intervals are installed vertically on the upper end of the column 60. The pole 70 is provided with a lampshade 82 to be described later on the top. Accordingly, the pole 70 separates the column 60 and the lampshade 82.

As shown in the pole pole 70, a plurality of rings 72 in the longitudinal direction may be installed at equal intervals by bolting or welding. This ring 72 partially emits the illumination light of the light source 50. That is, the illumination light is emitted between the gaps of the rings 72.

Subsequently, the lampshade 82 described above is installed horizontally on the top of the pole 70 as shown. The lampshade 82 closes the upper end of the column 60 on the pole 70 as shown. Therefore, the illumination light irradiated upward from the light source 50 is no longer irradiated upward by the lampshade 82.

Such lampshade 82 may be formed in a plate shape as shown, or may be formed in a conical shape, unlike shown. In addition, the lampshade 82 may vertically form the edge wall 82a at the edge as shown in the enlarged view "B" in the drawing.

Subsequently, the aforementioned reflecting plate 84 is integrally installed on the lower surface of the lampshade 82 as shown in the enlarged view "A" in the drawing. The reflective plate 84 may be made of a metal plate such as aluminum or chromium to enable light reflection, and alternatively, may be made of a metal plate or a plastic plate coated with the light reflection coating liquid, and alternatively, the lower surface of the lampshade 82 It may be configured by painting or painting the reflective coating liquid as described above. At this time, when coating the reflective coating liquid coating powder using high heat is preferable.

As illustrated, the reflective plate 84 specularly reflects the illumination light of the light source 50 irradiated to the lamp shade 82 to the lower portion of the column 60. That is, the illumination light of the light source 50 is irradiated to the reflecting plate 84. Thus, the light source 50 provides indirect illumination light to the ground through the reflecting plate 84.

Subsequently, the above-described floodlight plate 86 is integrally provided on the lower surface of the reflector plate 84 as shown in the enlarged view "A" in the drawing. The floodlight plate 86 is formed of a material capable of transmitting illumination light, it may be composed of a transparent material or a translucent acrylic or glass.

The floodlight plate 86 reflects a part of the illumination light irradiated from the light source 50 to the reflector plate 84 by the material properties. That is, the floodlight plate 86 does not transmit all of the illumination light irradiated to the reflector 84 without loss due to a material property of reflecting some light, and reflects a part of the illumination light to the opposite side. Of course, the floodlight plate 86 transmits most of the illumination light through the reflector plate 84 and reflects only a small amount of illumination light. Therefore, illumination light incident on the reflector plate 84 is attenuated by illumination intensity.

On the other hand, the lampshade 82 described above is fixed integrally to the upper end of the pole pole 70 by the fixing member. For example, the fixing member may be configured as a bolt B that vertically penetrates the lampshade 82 and is fastened to the upper end of the pole 70 as shown in the enlarged view "A" in the drawing. That is, the lampshade 82 is fixed to the pole pole 70 by bolting.

On the other hand, the above-described reflecting plate 84 and the light transmitting plate 86 is integrally coupled to the lower surface of the lampshade 82 by the coupling means. Such coupling means forms, for example, a bolt hole BH through which the above-described bolt B penetrates the reflecting plate 84 and the light transmitting plate 86 as shown in the enlarged view "A" on the drawing, and thus the bolt B ) Sequentially penetrates the lampshade 82, the reflector plate 84, and the floodlight plate 86, and is fastened to the pole 70, thereby integrally coupling the lampshade 82, the reflector plate 84, and the floodlight plate 86. Can be configured to That is, the bolt B integrally fixes the lampshade 82, the reflecting plate 84, and the light transmitting plate 86 on the pole table 70.

Thus, when configuring the coupling means bolt (B) secures the middle portion of the reflecting plate 84 and the floodlight plate 86 to the lampshade 82 as shown in the enlarged view "A". At this time, when the area of the reflecting plate 84 and the light transmitting plate 86 is large, the edge portion of the reflecting plate 84 and the light transmitting plate 86 may be bent downward by its own weight. That is, the reflecting plate 84 and the floodlight plate 86 is fixed to the center portion by the bolt (B), but the edge portion may be bent. Therefore, the coupling means needs to further include an edge fixing member for fixing the edges of the reflector plate 84 and the floodlight plate 86 to the edge of the lampshade 82.

The edge fixing member is composed of, for example, the auxiliary bolt 94 which is fastened to the edge of the lampshade 82 through the edge of the reflecting plate 84 and the floodlight plate 86 as shown in the enlarged view "B" in the drawing. can do. Accordingly, the reflecting plate 84 and the light transmitting plate 86 have a rim firmly fixed to the rim of the lampshade 82 by the auxiliary bolt 94. That is, the auxiliary bolt 94 is a member for fixing the edges of the reflector plate 84 and the floodlight plate 86 to the lampshade 82.

In addition, the edge holding member may further comprise a border plate 94a as shown in the enlarged view "B". The edge plate 94a not only supports the lower surface of the floodlight plate 86 as shown in enlargement, but also prevents the head of the auxiliary bolt 94 from being inserted into the floodlight plate 86.

On the other hand, the above-mentioned edge fixing member is protruded to the inside of the vertical wall 82a vertically formed at the edge of the lampshade 82, for example, as shown in the enlarged view "C" in the drawing, It can also be comprised by the inner side protrusion 82b which restrains the edge of the reflecting plate 84 and the transparent plate 86 provided. The inner protrusion 82b is preferably formed by beading the lower end of the vertical wall 82a inwardly as shown in an enlarged manner, and the reflecting plate 84 and the floodlight plate 86 are easily inserted into the lampshade 82. It is preferable to form a semi-circle as shown in enlargement.

Of course, when the reflecting plate 84 and the floodlight plate 86 is inserted into the vertical wall 82a of the lampshade 82, the number of the lampshades 82 may be slightly elastically deformed by self-elasticity according to the inner projection 82b. It is inserted into the straight wall 82a. Then, when the insertion is completed, while restoring the circular back to the inner projection (82b). Thus, the reflecting plate 84 and the floodlight plate 86 remain inserted into the vertical wall 82a of the lampshade 82.

Here, the above-described inner protrusion 82b may be integrally formed on the vertical wall 82a as shown, but unlike the illustrated example, the inner protrusion 82b may be manufactured separately from the vertical wall 82a by using a strip-shaped plate. It may be fixed to the straight wall 82a by bolting. That is, after preparing the strip-shaped plate, the lower end of the plate is beaded to form an inner protrusion 82b at the lower end, and then the upper end of the plate is fixed to the vertical wall 82a by bolting, and the inner protrusion 82b is provided. ) May protrude to the inner bottom of the vertical wall 82a. Thus, since the inner protrusion 82b is easily understood by those skilled in the art, detailed description thereof will be omitted.

On the other hand, the floodlight plate 86 may be provided with a diffuser plate 88 as shown in the lower center. The diffusion plate 88 is formed in a hemispherical shape as shown in the convex shape. Of course, as the diffuser plate 880 is convex, it protrudes convexly toward the lower center of the floodlight plate 86. Further, the diffuser plate 88 is mirror-machined to reflect the illumination light. As shown in FIG. 2, the light source 50 is spaced apart from the light source 50 embedded in the column 60.

The fine diffuser plate 88 is preferably configured to be fixed to the lampshade 82 by the bolt B as shown in the enlarged view "A" in the drawing. That is, the diffusion plate 88 is formed with a bolt hole (BH) through which the bolt (B) is penetrated as shown. Accordingly, the bolt B is fastened to the pole 70 after passing through the lampshade 82, the reflecting plate 84, the floodlight plate 86, and the diffusion plate 88.

In the indirect lighting street lamp according to the embodiment of the present invention configured as described above, the reflecting plate 84 is reflected by the light reflecting from the light source 50 to the bottom. At this time, the floodlight plate 86 transmits most of the illumination light to the reflector plate 84 and at the same time reflects a part of the illumination light directly without reflecting a part of the illumination light to the reflector plate 84 as shown in the enlarged view " A " do. Accordingly, the illumination light incident on the reflecting plate 84 is slightly attenuated and incident. Thus, the light source 50 provides illumination to the ground where the illumination is slightly attenuated.

On the other hand, the bolt B together with the lampshade 82 fixes the reflecting plate 84 and the floodlight plate 86 to the pole table 70. Therefore, the reflecting plate 84 and the floodlight plate 86 are easily installed in the lampshade 82.

On the other hand, when the diffuser plate 88 is provided in the lower center of the lampshade 82, the diffuser plate 88 is a column of the illumination light of the light source 50 that is projected to the central portion of the floodlight plate 86 as shown Reflects while diffusing to the bottom of 60). Therefore, the light source 50 may illuminate the ground more widely due to the diffused illumination light.

In conclusion, the reflecting plate 84 and the floodlight plate 86 specularly reflects the illumination light of the light source 50 irradiated to the edge of the lampshade 82 downward, and the diffuser plate 88 is irradiated to the center of the lampshade 82. Reflects downwards while diffusing the light source. In this way, the illumination light reflected by the diffuser plate 88 interferes with the illumination light reflected by the reflector plate 84 and the floodlight plate 86 while providing soft illumination.

Meanwhile, FIG. 3 is a side cross-sectional view showing that the dispersion protrusions are formed on the floodlight plate shown in FIG. 2, wherein the dispersion protrusions 86a as shown are provided to improve the damping efficiency of the floodlight plate 86. . That is, the dispersion projections 86a are provided to reduce light transmittance.

The dispersion protrusion 86a may be formed in a substantially triangular cross section as shown in the enlarged view "D" in the drawing. The dispersion protrusion 86a may be formed by molding, or alternatively, the surface of the floodlight plate 86 may be formed by scratching or by sending it by send blunt.

In this way, the dispersion projections 86a formed on the light transmitting plate 86 diffusely reflect a part of the illumination light as shown in the enlarged view "D", and let the remaining part enter the reflecting plate 84. That is, the dispersion protrusion 86a blocks a part of the illumination light from being incident on the reflecting plate 84. Therefore, the illumination light incident on the reflecting plate 84 is incident after the illumination intensity is attenuated more.

On the other hand, the dispersion protrusion 86a may be formed in a hemispherical shape as shown in the enlarged view "E" on the drawing by molding. Thus, the hemispherical dispersion protrusion 86a diffuses a larger amount of illumination light by the curved surface. Therefore, the illumination light incident on the reflector plate 84 is incident after the illumination intensity is further attenuated.

On the other hand, Figure 4 attached is a side cross-sectional view showing another embodiment of the floodlight plate shown in Figure 2, the floodlight plate 86 according to another embodiment is curved as shown. This floodlight plate 86 has irregularities as shown by bending. Thus, the light transmitting plate 86 is partially spaced apart from the lower surface of the reflecting plate 84 by recesses formed in the upper surface. Then, as shown enlarged by the convex portions formed on the lower surface, a part of the illumination light emitted from the light source 50 is diffusely reflected. Therefore, the illumination light incident on the reflecting plate 84 is incident after the illumination intensity is more attenuated. That is, the illustrated floodlight plate 86 has a better attenuation rate than the floodlight plate 86 shown in FIG. 2.

On the other hand, Figure 5 is a side cross-sectional view showing another embodiment of the floodlight plate shown in Figure 2, the floodlight plate 86 according to another embodiment forms a bubble (86c) therein during molding One is the difference from the floodlight plate 86 described above.

In this way, in the transparent plate 86 on which the bubbles 86c are formed, the bubbles 86c diffusely reflect a part of the illumination light as shown in an enlarged view. Of course, the floodlight plate 86 as shown injects the remaining part of the illumination light to the reflector plate 84. Therefore, the illumination light incident on the reflecting plate 84 is incident after the illumination intensity is attenuated more. That is, the illustrated floodlight plate 86 has a better attenuation rate than the floodlight plate 86 shown in FIG. 2.

The indirect lighting street light according to the present invention as described above, because the floodlight reflects or diffusely reflects a part of the illumination light, there is an effect that can reduce the illuminance of the illumination light reflected from the reflector.

In particular, when the dispersion projections or bubbles are provided on the floodlight plate or when the floodlight plate is formed to be bent, the illumination intensity of the illumination light may be more attenuated.

In addition, since the reflecting plate and the floodlight plate are fixed to the lampshade by bolts fixing the lampshade to the pole, there is also an effect that the reflector and the floodlight plate can be easily fixed to the lampshade.

In addition, when the weight of the reflector and the floodlight plate is heavy, the edges of the reflector and the floodlight plate can be fixed to the edge of the lampshade by the auxiliary bolt of the edge fixing member, so that the reflector and the floodlight plate can be stably fixed to the lampshade. .

On the contrary, when the weight of the reflector and the floodlight is heavy, the edges of the reflector and the floodlight can be fixed to the edge of the lampshade by the inner projection of the edge fixing member, so that the reflector and the floodlight can be stably fixed to the lampshade. There is also an effect that can be fixed very easily.

In addition, when the diffuser plate is provided at the center of the lampshade, the diffuser plate reflects while diffusing the illumination light, thereby providing a wider illumination on the ground.

Since the above embodiments are merely illustrative of preferred embodiments of the present invention, the scope of application of the present invention is not limited to the above, and appropriate modifications are possible within the scope of the same idea. Therefore, since the shape and structure of each component shown in the embodiment of the present invention can be carried out by deformation, it is natural that the modification of the shape and structure belong to the appended claims of the present invention.
