Street lamp having fine dust measurement function {Street lamp having fine dust measurement function}

The present invention relates to a street lamp device, and more particularly, to a street lamp device having a fine dust measurement function that can measure the concentration of fine dust on the street lamp installed on the side of the road.

In general, outdoor lights such as street lights or security lights (hereinafter referred to as 'street lights') are installed at regular intervals along roads such as sidewalks and roadways to illuminate the surrounding area at night to provide safety for pedestrians traveling at night and pedestrian traffic. It plays a role of convenience.

Such a street lamp is a lighting device installed outdoors, and is exposed to pollutants in the atmosphere.

In this atmosphere, various suspended dusts having a diameter of 0.1 μm to 100 μm exist. Among them, dust having a diameter of 2.5 μm or less is classified as fine dust “PM2.5”, and diameters of 2.5 μm to 10 μm are fine. Divided into dust "PM10".

PM2.5 is known to increase early mortality with asthma, allergic rhinitis, bronchitis, emphysema, alveolar damage, etc. by prolonged infiltration into the alveoli without being filtered by the nasal mucosa during prolonged inhalation. In order to systematically regulate the causes of fine dust, we install a fine dust measuring device in a specific place to continuously detect the fine dust generation area, the timing and concentration of occurrence. It is informed in real time.

In particular, although street lamps are installed in various places along the road where the exhaust gas is the most common cause of air pollution, there is no additional measurement function to measure the fine dust. Fine dust is being measured.

In addition, the street lamp installed as described above illuminates the surrounding area by illuminating light emitted from the light source. In this case, when the street lamp is installed adjacent to a residential area, a part of the light emitted from the light source directly illuminates the residential area overnight. Light pollution is caused, and such light pollution occurs more seriously when the light source is provided with a strong LED.

Thus, conventionally, in the Republic of Korea Patent No. 10-1446889 'light fixture having a shield for preventing light pollution' has been proposed.

However, the luminaire disclosed in Korean Patent No. 10-1446889 is not provided with a function for measuring fine dust, but also adopts a light shield applying a radiation limit shield to the lamp housing. Since it is fixed to the housing and the luminaire is fixed to the prop, it is a fixed structure that cannot control the direction of irradiation of the luminaire. Therefore, it is possible to block light pollution in a certain form only in a specific area, and the amount of light lost than the light pollution blocking is There are many disadvantages of low lighting efficiency.

On the other hand, the operation of the motor 110 as described above can be controlled remotely by a control box (not shown) or a remote control, etc. provided in the holding (100) the outdoor light manager, or by using a communication means in the outdoor light control station motor ( The operation of 110 may also be controlled remotely.

The operation relationship of the street lamp device having a fine dust measurement function according to the present invention as described above will be described.

Street light apparatus of the present invention is provided at a predetermined interval on the side of the road by measuring the fine dust concentration in various areas to provide in real time.

That is, as shown in Figure 3, the air in the atmosphere is introduced into the air inlet pipe 420 through the inlet 422 is introduced into the fine dust measurement unit 410 through the hopper portion 421 of the lower.

In this process, when the air flows through the heating unit 430 into the hopper unit 421, the heating coil 432 is operated by receiving the power of the self-generated power or the street light by the solar panel 440. The operating fluid in the heat generating unit 431 is heated by the operation of the coil 432, the heated working fluid is dried by heating the air flowing through the air inlet pipe 420.

If the air is not dried in this way, water molecules in the air flowing into the measuring unit 410 affect the operation of the optical sensor, and thus the light irradiated from the foot unit 411 is not only fine dust but also water molecules. Reflected or refracted to affect the light collection efficiency in the light receiving unit 414, a significant error occurs in the measured value. Therefore, the air flowing through the air inlet pipe 420 by the heating unit 430 must be heated to lower the humidity in the air as described above.

On the other hand, when the air dried as described above is introduced into the measuring unit 410, is moved away from the upper portion of the measuring unit 410, at this time, the light generated from the overpass 411 in the measuring unit 410 is hit The concentration of the fine dust is measured by measuring the concentration of light passing through the fine dust region while being irradiated toward the light receiving unit 414.

As such, since the fine dust measuring unit 400 is provided for each street light, the fine dust concentration in each road where the street light is installed can be measured and provided in real time.

In addition, a large amount of heat is generated from the LED of the LED module 300 and the PCB on which the LED is mounted when the street lamp device is operated. In this case, high temperature heat is generated from the LED, but the heat is the LED module. Rapid heat conduction is achieved by the first heat dissipation plate 320, the second heat dissipation plate 340, and the heat pipe 330 provided in contact with the upper surface of the 300 to dissipate heat.

In particular, since the plurality of heat pipes 330 provided between the first and second heat sinks 320 and 340 are provided adjacent to each other at the center of the first heat sink 320 corresponding to the position of the LEDs, the heat pipes 330 are generated in the LEDs. By quickly dissipating the high temperature heat to be able to prevent breakage and shortening the life of the LED module 300 due to the temperature rise.

On the other hand, the street lamp device as described above, as shown in Figs. 6 and 7, the LED module 300 is a state in which the surrounding light around the outdoor light toward the ground, the light shielding plate 350 of the second heat sink 340 It is operated in a state in which both are raised to the top.

In this state, when the module housing 200 is rotated in a direction in which illumination is required to prevent light pollution, the light shielding plate provided on the side opposite to the rotation direction of the module housing 200 together with the rotation of the module housing 200. 350 is drawn to the light source side to cover the light, thereby completely blocking the light pollution in the lighting restriction area.

8 and 9, when the motor 110 is driven and the driving gear 120 is rotated counterclockwise as shown in FIG. 9, a ring gear fixed to an inner circumference of the module housing 200 is provided. 220 is also rotated in a counterclockwise direction, so that the module housing 200 is rotated counterclockwise as shown in FIG. 9 while being coupled to the support 100 to provide illumination in the right region, It will limit the lighting.

At this time, the module housing 200 which is rotated in a state coupled to the support 100 rotates about the center of the ring gear 220, that is, the second rotation shaft 370.

Meanwhile, with the movement of the module housing 200 as described above, the light shielding plate 350 on the left side is drawn out when the right side of the module housing 200 rotates, based on FIG. 9. The meshed interlocking gear 140 is rotated counterclockwise, and the first rotation shaft 150 fixed to the interlocking gear 140 is also rotated counterclockwise like the interlocking gear 140 and the first rotation shaft 150. The first sprocket wheel 151 fixed to) is also rotated counterclockwise.

Then, the second sprocket wheel 371 connected to the first sprocket wheel 151 and the chain 152 is also rotated counterclockwise, and the second rotation shaft 370 to which the second sprocket wheel 371 is fixed is a support block. The pinion gear 380 fixed thereto is rotated counterclockwise while being rotated counterclockwise in place.

Thus, as the pinion gear 380 is rotated in the counterclockwise direction, the gear portion 381 of the pinion gear 380 is engaged with the rack gear 351 of the left light shielding plate 350 to thereby form the light shielding plate 350. The light source plate is lowered to the side of the light source, and the rack gear 351 of the right light shielding plate 350 is positioned so that the inorganic gear 382 of the pinion gear 380 is in a state where power is cut off. 2 The heat sink 340 is maintained in the state positioned above.

At this time, the LED module 300 is rotated integrally like the module housing 200 separately from the second rotation shaft 370 around the second rotation shaft 370, the pinion gear 380 is the LED module 300 At the same time as the rotation of the second rotation shaft 370 and integrally rotated in the same direction as the LED module 300, in this process both the LED module 300 and the pinion gear 380 simultaneously rotates the second rotation shaft 370 Since it is rotated as a reference, malfunctions due to interference between the pinion gear 380 and the rack gear 351 can be eliminated.

Then, the light blocking plate 350 is drawn out from the moment when the gear part 381 of the pinion gear 380 rotated as described above is engaged with the rack gear 351 of the light blocking plate 350.

Therefore, as described above, the LED housing 300 is rotated by the module housing 200 to protect the lighting proposal area from the light as much as possible, while the pinion gear 380 is rotated at the same time as the rotation of the LED module 300, thereby limiting the lighting area. By taking out the light shielding plate 350 on the side, the light restriction area can be reliably covered and protected from the light, thereby making it possible to reliably block light pollution.

Although the present invention has been described in detail through specific examples, it is intended to describe the present invention in detail, and the present invention is not limited thereto, and should be understood by those skilled in the art within the technical spirit of the present invention. It is obvious that the modification and improvement are possible.

All simple modifications and variations of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be apparent from the appended claims.
