The present invention relates to a street lamp system, and more particularly, for outdoor health lighting to systematically perform quantitative illuminance plan (brightness plan) and qualitative illuminance plan (light output) simultaneously in street lighting for vehicles or pedestrians. The present invention relates to a street light system having illumination and a method of operating the same.

In general, outdoor health lighting means designing by quantitative illumination plan and qualitative illumination plan according to the arrangement and arrangement of lighting fixtures, the installation interval and height of lighting fixtures, the predetermined lighting method and the selection of lighting fixtures suitable for the space. do.

Quantitative illuminance plan refers to physical brightness plan based on physical and physiological aspects, and qualitative illuminance plan refers to directing illumination plan based on mental, emotional, psychological and social aspects.

In particular, street lighting using streetlights is intended for vehicles, pedestrians, natural objects, installations, etc., and promotes safe use under dark conditions by creating a night environment that can induce a quick, accurate and convenient view of the road users. It should be planned for the purpose.

Since the plan of street lighting has a great influence on the lighting evaluation of the entire space, it is necessary to understand the lighting balance with each space and plan the lighting.

In particular, the qualitative illuminance plan is very important for the selection of lighting fixtures, installation height, arrangement, arrangement, and light source to improve the mental and physical health of the user.

Nevertheless, looking at the current street lighting, most street lamps are installed according to quantitative illuminance plan considering only brightness, and damage to trees or deterioration of lighting efficiency due to inadequate street lamp layout plan. By giving the following brightness to hide the potential obstacles users are likely to physically threaten.

In particular, if the height of the street lamp is not appropriate, light pollution (hereinafter referred to as 'light pollution') may occur to the users.

As shown in Fig. 1, the street lamp 1 according to the prior art is a metal halide lamp (MH) 175W based on the installation standard of Article 5 (security lamp and street lamp equipment) of the home electrical design guideline (2003). Is used as a light source, and security lamps are to be installed within 50m of the installation interval in Article 33 of the Regulations on Housing Construction. Here, the column 2 of the street lamp 1 is installed and arranged in a straight line.

However, although the conventional street lamp is set higher than the height of a sculpture, such as a wall, or a natural object, such as a tree, it does not depend on an appropriate street lamp layout plan (quantitative and qualitative illuminance plan), but merely satisfies the installation criteria.

That is, the conventional street light 1 uses only one fixed light source 3 irradiated indiscriminately in the upward direction or in the width direction without considering the characteristics and shapes of the light distribution. There is a disadvantage that can be confusing to pedestrians or users by interference with the surrounding sculptures.

In addition, the conventional street light 1 has a disadvantage in that it is uneconomical because the electricity consumption is relatively high according to the use of the light source 3 that consumes the same amount of power of 175W during the use time.

These conventional metal halide lamps have a cold color of light, which makes it impossible to impart a feeling of light, and may deteriorate emotional and psychological health. Since the size of the lamp is relatively large, the lamp assembly is relatively large and placed on the column. It has been aesthetically bad.

In addition, a cut-off system that does not emit light in the conventional street light (1), that is, cut off the emission of light in an undesired area and direction to improve visibility and prevent light seas caused by light, thereby improving the efficiency of the road surface ( Although there is a cut off system, it is only suitable for quantitative illuminance planning, and there is a disadvantage in that it is impossible to realize outdoor health lighting according to qualitative illuminance planning.

Here, while the street lamp 1 according to the conventional cut-off system is more efficient to secure the roughness of the road surface than the widely used diffused light distribution, there is a disadvantage that the space users perceive the street lamp 1 dark from the outside, Therefore, due to the absence of means that can produce a variety of spatial atmospheres are less useful.

Accordingly, an object of the present invention is to solve the problems described above, and to install an auxiliary lamp on the top of the column having a main lamp, and to control the lighting of the main lamp and the auxiliary lamp through a predetermined operating method hourly. Accordingly, a space user has a street light system and a method of operating the same, which can provide an emotional and psychologically stable space without causing stress or anxiety due to the street light.

In addition, another object of the present invention is that the auxiliary light and the main light can be selectively turned on according to the degree of darkness or time, can be utilized for the purpose of atmosphere when performing the event in the installation space, the rotation of the auxiliary light and the main light It is to provide a street light system having a directing light that can selectively adjust the direction of irradiation according to the tilt of and a method of operating the same.

The object of the present invention described above is a street lamp system having a directing light having a column that is assembled after the concrete is placed, having a main lamp installed on the upper side of the column and the auxiliary lamp coupled to the upper end of the column A street lamp body; And a lighting control system in charge of controlling the power supply of the main lamp and the auxiliary lamp so that the street lamp main body can be turned on and off based on a quantitative illuminance plan, a qualitative illuminance plan, and a survey result about the walking amount of the space user. The lighting control system includes a power input terminal connected to an external power source; A control circuit connected to the power input terminal and having a power supply unit, a time control unit, and an illuminance measuring unit configured to be electrically and electronically configured to control the lighting time, order, and directing of the main lamp and the auxiliary lamp; And an output stage connected to the control circuit and connected to supply the controlled power to the main lamp and the auxiliary lamp, respectively.

Hereinafter, with reference to the accompanying Figures 2 to 6 will be described in detail with respect to the street lamp system having a directing light and its operating method according to a preferred embodiment of the present invention.

In the drawings, FIG. 2 is a front view for explaining a street light system having a directing light and a method of operating the same according to an embodiment of the present invention, and FIG. 3 is a view illustrating a configuration of a streetlight system having a directing light shown in FIG. Block diagram. In addition, Figure 4 is a cross-sectional view for explaining the coupling relationship of the auxiliary lamp of the street lamp system having the production lighting shown in Figure 2, Figure 5 is an enlarged cross-sectional view taken along the line AA shown in Figure 4, Figure 6 FIG. 2 is a light distribution curve diagram of a street light system having the directing illumination shown in FIG. 2.

First, as shown in FIG. 2, the present invention largely consists of a street lamp main body 10 and a lighting control system 20 that performs lighting control thereof.

The street lamp main body 10 is a light pole which is assembled after concrete installation so that the illumination direction, irradiation amount, lighting time, and light color can be selectively changed according to a space where surrounding houses, walls, sculptures, and natural objects are installed. The main lamp 100 is installed at the upper end side of 11), and the auxiliary lamp 200 is attached to the upper end.

Arrangement and arrangement of the street light main body 10 is the simulation verification result, it is important to be placed in the proper position rather than the interval, for this reason, to be within the existing installation interval 50m. At this time, the results of simulation examination by intervals (eg, 30m, 40m, 50m) showed a slight average roughness difference of less than 1 lux. However, in the present invention, since there is a large roughness difference according to the arrangement, the cross of the difference in average roughness value of each section is smaller than the one-sided arrangement in which the difference in average roughness value of each section on which the other side is built based on one side light 11 is larger. As the columnar 11 is erected in an array, it is desirable to eliminate the deviation of the light and dark.

For example, in the case of installation in a range, etc., it is preferable to arrange in a diagonal direction, but maintain the section distance of about 30m to about 40m. In addition, when disposed on a staircase having a middle horizontal plane of the stairs, the illumination is placed on the middle horizontal plane rather than the top or bottom of the stairway, the illumination to illuminate the stair step surface so that no shadow occurs on the part or the front surface of the stairs.

The lamp column 11 of the street lamp main body 10 is installed to have a predetermined height (for example, 4.5 m) from the road surface, and is supplied with power by using a flag installation mechanism, a rung for arranging the light sources at a spaced position, and solar heat. In case of using as a main power source, it is preferable to attach a solar generator attachment device such as a solar panel and a solar tracking drive device, or a wind generator to replenish power using wind power or to use as a main power source.

The column 11 is a hollow shaft or a solid shaft of a steel pipe, the first installation portion 11a having a jaw formed on the circumferential surface to install the main lamp 100 on the upper side of the column 11, and the auxiliary lamp ( 200 is placed in the upper end in accordance with the axial direction of the column 11, the hollow protruding and protruding upward from the shaft center of the column 11 to support the auxiliary lamp 200 so as to be rotatable It has two mounting parts 11b.

In the operating method of the street lamp system having the directing light according to the present invention, the lighting is controlled according to the brightness of the surrounding area and the time of use of the street lamp based on the survey result.

That is, the lighting control system 20 having the following time control unit, illuminance measuring unit, and power supply unit is a usage time in which the amount of walking is normal according to the quantitative illuminance plan and the qualitative illuminance plan, and the ambient brightness is from bright to dark. A first lighting step of lighting one auxiliary lamp 200 in a first time zone using a transition lamp (for example, between 19:30 and 20:30 in the case of the lower limb and between 17:30 and 18:30 in the case of a winter solstice); ; According to the survey results, people walked the most during the 2nd time using streetlights with the darkest brightness (eg, between 20:30 and 22:00 for lower limbs and between 18:30 and 20:00 for winter solstices). A second lighting step of lighting two lamps 100 and two auxiliary lamps 200; According to the survey results, the walking time is the normal usage time, and the third time zone using street lamps where the ambient brightness transitions from dark to bright (for example, in the case of the lower limbs, between 22:00 and the predetermined off time when the ambient light becomes bright due to the sunlight measuring unit detecting sunlight) In the case of a winter sol, the lighting control of the street lamp main body 10 is performed by including a third lighting step of lighting one main lamp 100 between 20:00 and a predetermined extinguishing time.

As shown in FIG. 3, the lighting control system 20 includes a power input terminal 22 connected to an external power source 21; Connected to such a power input terminal 22 is configured as an electrical and electronic circuit to control the lighting time, sequence, lighting direction of the main lamp 100 and the auxiliary lamp 200 of the street lamp body 10 in the above operating method A control circuit having a power supply unit 23, a time control unit 24, and an illuminance measurement unit 25; It is composed of an output terminal 26 connected to such a control circuit and connected to supply the controlled power to the main lamp 100 and the auxiliary lamp 200, respectively.

Here, the power supply unit 23 receives the time control unit 24 and the time control value and the illuminance control value of the illuminance measuring unit 25 to turn on the main lamp 100 and the auxiliary lamp 200 at the same time, or both. Control the power supply to light only one.

The time control unit 24 calculates the time control value so that the power supply is supplied to the main lamp 100 and the auxiliary lamp 200 for each time zone by dividing the lighting time into the ground and the winter solstice by the timer function. It serves to input.

The illuminance measuring unit 24 uses a CdS sensor or the like whose resistance value is changed according to the surrounding brightness, such that the ambient brightness is changed from bright to dark, the ambient brightness is darkest, or the ambient brightness is changed from dark to bright. It is responsible for calculating the illuminance control value corresponding to each of the situations to be input to the power supply unit (23).

The output terminal 26 of the lighting control system 20 includes a plurality of wire connection sockets capable of supplying power in parallel to the plurality of street lamp bodies 10.

Each wire connecting socket is electrically connected to one end of the pair of wires 27 and 28, and the wires 27 and 28 extend through the underground buried part and the inside of the column 11, and then the other end thereof. It is electrically connected to the bulb socket of the main lamp 100 and the auxiliary lamp (200).

The bulb socket of the main lamp 100 is formed to combine the first bulb 101 such as the product name 'CDM 150W' according to the corresponding bulb fastening method, and the bulb lamp of the auxiliary lamp 200 is the product name 'FEL / The second bulb 201, such as EL 20W 'is formed to be coupled according to the light bulb fastening method.

Here, the first bulb 101 such as the 'CDM 150W' is to satisfy the purpose of securing the illuminance and the quantitative illuminance plan, and has a relatively small size compared to the conventional 175W such as the metal halide. It is easy and enables the design of a compact main lamp (100). In particular, the first bulb 101 has a slightly cold color temperature, but any light bulb product that enables clear illumination can be used, and is not limited to a specific light bulb product in the description of the present invention.

Since the main lamp 100 having such a first bulb 101 is attached to the first installation portion 11a of the column 11 as a tilt structure, the irradiation direction and angle can be adjusted as necessary. Lighting designers can irradiate light only on the desired road surface, and it has very small power consumption compared to the previous 'metal halide lamp 175W', which is very economical, and the light source efficiency is high, thereby saving energy.

That is, the main lamp 100 includes a cover 103 in which a transparent globe panel is coupled to a portion which is opened downward; A reflection plate 102 formed inside the cover part 103 to reflect light downward; It is fixed to the reflecting plate 102 has a light bulb socket for coupling the first bulb 101.

The cover portion 103 is to be tilted (t) at a finite rotation angle in the bracket 110 coupled to the first installation portion (11a) of the column 11 in order to implement a tilting structure with a fixed bolt axis. It is coupled to the fixing bolt so that it can be.

The main lamp 100 having the first electric bulb 101 and the cover 103 can adjust its upper and lower irradiation angles based on the lamp column 11, and also release the fixing bolt of the bracket 110 to release the first bolt. When rotating the bracket 110 coupled to the mounting portion 11a, the left and right irradiation direction can be adjusted. The electric wire 27 for the main lamp 100 is led into the wire passage of the bracket 110 from the inside of the column 11, and then electrically connected to the electric bulb socket in the cover 103.

On the other hand, the second bulb 201, such as 'FEL / EL 20W' is a light bulb product used in qualitative illumination plan in order to give a feeling of light, such as a bollard lighting fixture, a slightly cold feeling of the first bulb 101 Of course it can be any light bulb product that serves to complement the color temperature of the soft and gentle lighting feeling, of course, is not limited to the specific light bulb products in the description of the present invention.

The second light bulb 201 secures a disadvantage that users or pedestrians who see the light by the first light bulb 101 of the main lamp 100 from a distance are darkly aware of the light, and the first warm and emotional light of the diffusion lighting device. Variablely added to the light by the bulb 101.

The second bulb 201 is wrapped by a cylindrical glove 210. Cylindrical glove 210 has a cross-sectional size corresponding to the cross-sectional area of the column 11, it is well matched with the column 11, and is formed of a translucent diffusion-permeable plastic material for diffusion lighting and atmosphere. The auxiliary lamp 200 having such a cylindrical glove 210 is rotated (r) at the upper end of the column 11 by the rotating structure to be described below.

Here, as described above, the second mounting portion 11b is a hollow protrusion having a thread and protrudes upwardly from the axis of the column 11, and couples the rotary sealing means 202 such as a bearing to its outer peripheral surface. have.

Further, the thread of the second mounting portion 11b has a counter threaded hole formed at the lower portion thereof, a wire passage 203 formed at the shaft center, and a socket support plate 204 having a diameter relatively smaller than the inner diameter of the cylindrical glove 210. Is coupled to.

The socket support plate 204 is vertically provided with a light bulb socket 205 corresponding to the second bulb 201 by screws or the like. The bulb socket 205 is coupled to the second bulb 201 is to receive power from the wire.

On the other hand, the glove support plate 206 is coupled to the outer circumferential surface of the rotation airtight means 202 such as a bearing so as to be rotated by the second mounting portion 11b of the column 11.

On the outside of the glove support plate 206, a screw rim portion 207 for screwing the cylindrical glove 210 vertically is projected vertically.

Inside the screw rim portion 207, a double wall filter mounting portion 208 for mounting the color filter 220 of a predetermined shape (for example, 'C' shape) to be described below is vertically protruded.

In addition, the lower end of the cylindrical glove 210 is screwed to the screw rim portion 207, the glove cover 209 is screwed to the upper end of the cylindrical glove 210.

The globe cover 209 serves to open and close the upper end of the cylindrical globe 210 as necessary, and the installer can easily replace the second bulb 201 or the color filter 220 coupled therein. .

When the installer grasps and rotates the cylindrical globe 210 by hand, the glove cover 209, the cylindrical globe 210, the color filter 220, and the glove support plate 206 are attached to a rotational sealing means 202 such as a bearing. While rotating by the second installation portion 11b, the socket support plate 204, the bulb socket 205, the second bulb 201 of the column 11 does not rotate.

The color filter 220 may provide a light diffusion type directing effect in response to the qualitative illuminance plan related to the present invention, and the color color may be replaced to correspond to an event event.

In particular, the color filter 220 forms an open portion 221, and emits a relatively large amount of diffused light through the open portion 221, to produce a natural color through the unopened portion, It is possible to adjust the characteristics and shape of the entire light distribution of the street light having the present invention lighting corresponding to the rotation direction of the lamp 200.

That is, as shown in the light distribution curve shown in FIG. 6, when only the main lamp is turned on, the light distribution characteristic is the same as the area indicated by the thick solid line curve 91, and when only the auxiliary light is turned on, the hidden line curve 92 is used. It has the same light distribution characteristics as the displayed area. In addition, when both the main light and the auxiliary light is turned on and rotated in any direction, the light distribution characteristic is the same as the area indicated by the dashed-dotted line curve 93.

At this time, the hidden line curve 92 or the dashed-dotted line curve 93 is variable according to the rotation angle of the auxiliary lamp, and also the area of the thick solid line curve 91 is also variable according to the tilt angle.
