Description

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

The present invention relates to a street light device, and more particularly, to a street light device having a fine dust measurement function capable of measuring the concentration of fine dust in a street light installed on a roadside.

In general, outdoor lights such as street lights or security lights (hereinafter referred to as 'street lights') are installed at regular intervals on roadsides such as sidewalks and driveways to illuminate the surrounding area at night to ensure the safety of vehicles operating at night and pedestrian traffic. It serves as a convenience.

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

In this atmosphere, there are various floating dusts with a diameter of 0.1 μm to 100 μm, among which 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. It is classified as "PM10" dust.

PM2.5 is known to increase premature mortality with asthma, allergic rhinitis, bronchitis, emphysema, and alveolar damage by infiltrating deeply into the alveoli without being filtered by the nasal mucosa during prolonged inhalation, protecting the health of citizens and residents in the Ministry of Environment In order to do so, the cause of fine dust is systematically regulated, while a fine dust measuring device is installed in a specific place to continuously detect the fine dust generation area, generation time, and concentration, and then the relevant information can be obtained through the situation board or daily forecast. It is notifying in real time.

In particular, even though street lamps are installed in various places on the roadside where exhaust gas, which is the main cause of air pollution, is installed, there is no additional measurement function to measure 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, in the related art, in Korean Patent No. 10-1446889, a 'lighting fixture having a shield for preventing light pollution' has been proposed.

However, the lighting luminaire disclosed in Korean Patent No. 10-1446889 is not provided with a function to measure fine dust, but also adopts a light shield to which a shield for radiation angle limitation is applied to the lamp housing, but the shield is a lamp. Since it is fixed to the housing and the luminaire is fixed to the post, it is a fixed structure that cannot adjust the irradiation direction of the luminaire, so 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 There are many disadvantages of low lighting efficiency.

That is, as shown in FIGS. 8 and 9, when the module housing 200 is rotated to the right to provide illumination in the right region and the left region is intended to limit the illumination, the left side of the light shielding plates 350 on both sides The blanking plate 350 is drawn out and blocks light from being irradiated to the left light-restriction area, thereby preventing light pollution.

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

The street light device of the present invention is installed and provided at regular intervals on the side of the road to measure the concentration of fine dust in various areas and provide it in real time.

That is, as shown in FIG. 3, air in the air flows into the air inlet pipe 420 through the inlet 422 and flows into the fine dust measuring unit 410 through the lower hopper part 421.

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

If the air is not dried as described above, water molecules in the air flowing into the measurement unit 410 affect the operation of the optical sensor, and the light irradiated from the foot unit 411 is not only fine dust, but also water molecules. Since it is reflected or refracted, it affects the light collection efficiency in the light receiving unit 414, and thus a considerable 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.

On the other hand, when the dried air as described above flows into the measuring unit 410, it is moved away from the upper portion of the measuring unit 410, and at this time, the light generated from the foot unit 411 in the measuring unit 410 is hit. As it is irradiated toward the piece light-receiving unit 414, the concentration of fine dust is measured by measuring the concentration of light passing through the fine dust region.

As described above, since each particle is equipped with a fine dust meter 400, it is possible to measure and provide the fine dust concentration in real time on each road where the street light is installed.

In addition, a large amount of heat is generated from the LED of the LED module 300 that is lit when the street light device is operated as described above, and the PCB on which the LED is mounted. At this time, high temperature heat is generated from the LED, but this heat is the LED module. Rapid heat conduction is performed by the first heat sink 320, the second heat sink 340, and the heat pipe 330 provided in contact with the upper surface of the 300 to radiate heat.

In particular, the plurality of heat pipes 330 provided between the first and second heat sinks 320 and 340 are provided adjacent to each other in the center of the first heat sink 320 corresponding to the position of the LED, and thus are generated in the LEDs. By rapidly dissipating high-temperature heat, it is possible to prevent damage to the LED module 300 due to temperature rise and shortening of life.

Meanwhile, as shown in FIGS. 6 and 7, the street light device as described above is in a state in which the LED module 300 illuminates the outdoor light in a state facing the ground, and the light shielding plate 350 of the second heat sink 340 It is operated in a state in which all of them are raised upwards.

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 opposite side to the rotation direction of the module housing 200 together with the rotation of the module housing 200 When the 350 is drawn to the light source side and obscures the light, it is possible to completely block light pollution in the light limited area.

If this is described in detail with reference to FIGS. 8 and 9, when the motor 110 is driven and the drive gear 120 is rotated counterclockwise as in FIG. 9, the ring gear fixed to the inner circumference of the module housing 200 (220) is also rotated in a counter-clockwise direction, the module housing 200 is rotated counterclockwise as shown in Figure 9 in a state coupled to the holding 100 to provide illumination to the right area, to the left area It will limit lighting.

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

On the other hand, in addition to the movement of the module housing 200 as described above, the light shielding plate 350 on the left is withdrawn when the module housing 200 is rotated on the basis of FIG. 9, which is rotated when the ring gear 220 is rotated. The meshed interlocking gear 140 is rotated counterclockwise, and the first rotational shaft 150 fixed to the interlocking gear 140 is also rotated counterclockwise like the interlocking gear 140, and the first rotational shaft 150 The first sprocket wheel 151 fixed to) is also rotated counterclockwise.

Then, the second sprocket wheel 151 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 in a fixed state coupled to 344.

As a result, as the pinion gear 380 is rotated counterclockwise, the gear portion 381 of the pinion gear 380 is engaged with the rack gear 351 of the left light shielding plate 350 to bring the light shielding plate 350 into account. The LED light source is lowered to the side, and the right light blanking plate 350 is made of the power because the inorganic gear 382 of the pinion gear 380 is located on the rack gear 351 of the right light blanking plate 350. 2 The heat sink 340 is maintained at the upper position.

At this time, the LED module 300 is rotated integrally as the module housing 200 separately from the second rotating shaft 370 around the second rotating shaft 370, and the pinion gear 380 is the LED module 300. Simultaneously with the rotation of the second rotation axis 370, the LED module 300 is rotated integrally in the same direction. In this process, both the LED module 300 and the pinion gear 380 simultaneously rotate the second rotation axis 370. Since it is rotated as a reference, malfunction caused by 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 module 300 is rotated by the module housing 200 to protect the light-restricted area from light as much as possible while the pinion gear 380 is rotated at the same time as the LED module 300 is rotated. By drawing out the light shielding plate 350 on the side, the light-restricted area can be concealed and protected from light, so that light pollution can be reliably blocked.

Although the present invention has been described in detail through specific embodiments, the present invention is specifically for describing the present invention, and the present invention is not limited to this, and by those skilled in the art within the technical spirit of the present invention. It is clear that the modification and improvement are possible.
