A plurality of interlocking bar through holes 2122a are formed in the interlocking bar 2122, and each interlocking bar through hole 2122a is an interlocking bar connection hole of the module coupling unit 2121 coupled to each module fixing frame 1000 ( 2121c) is rotatably coupled to all the module coupling parts 2121 coupled to the interlocking bar 2122 are interlocked to be adjusted at the same angle.

That is, all modules (control module/light source module) connected to the interlocking bar by the interlocking bar 2122 are interlocked and moved at the same inclination.

A sector gear (2121d) on any one of a plurality of module coupling parts (2121) coupled to each module mounting protrusion (1200) of the module fixing frame (1000) and an interlocking bar connection hole (2121c) upper part is formed

The sector gear 2121d is engaged with the spur gear 2112a, and when the spur gear 2112a rotates, the sector gear 2121d also rotates with the module mounting protrusion connection hole 2121b as a central axis.

Each module (control module/light source module) coupled to the lower end of the module coupling part 2121 when the sector gear 2121d rotates around the module mounting protrusion connection hole 2121b has a module mounting protrusion connection hole 2121b. It rotates in the opposite direction to the sector gear 2121d about the center.

A plurality of LED chips that emit electrical energy as light are disposed in the light source module 2300 .

The control module 2200 is provided with a control unit 2210 that rotates the motor 2111 forward and reverse in response to an operation signal.

The control module 2200 is provided with a gyro sensor 2220 for sensing the inclination.

That is, the control module 2200 adjusts the inclination of each module.

When the control module is set to the automatic mode, the control module 2200 determines that the inclination of the control module 2200 sensed by the gyro sensor 2220 mounted on the control module 2200, that is, the inclination of the bottom surface of the control module is horizontal. If not, the control module 2200, which is operated in conjunction with the motor 2111 by rotating the motor 2111 forward and backward through the control unit 2210 by the sensing value of the gyro sensor, is automatically operated to achieve a horizontal level.

The control module 2200 is provided with a laser unit 2230 that emits red light.

At this time, since the light emitted from the laser unit 2230 has to be emitted from the outermost part of the light emitted from the street lamp head, it is easy to see with the naked eye whether the light emitted from the street lamp causes light pollution. The module 2200 is preferably disposed at the outermost part of the street lamp head, that is, at the outermost part of the plurality of modules (control module and light source module) disposed in the street light head.

The laser unit 2230 is a means for recognizing whether the angle adjusting means is in operation, and in the initial stage of the automatic mode or the manual mode for manually adjusting the angle of the module, the laser unit 2230 emits laser light to the module. It can be easily recognized with the naked eye whether the angle control function of is difficult)

That is, the laser unit 2230 is operated only in the initial stage of operation in both automatic mode and manual mode, and the laser unit 2230 is operated to blink at a certain period, so that the operator can visually check whether the light source module 2300 angle adjusting means is operating without any abnormality. easily recognizable.

The operation time of the laser unit 2230 is preferably set to 30 seconds.

The operation of the control module 2200 is preferably performed by transmitting an operation signal to the control unit 2210 by a remote controller (remote control).

When explaining the angle adjustment operation of the street lamp based on the above configuration,

The motor 2111 is rotated forward/reverse by the electric signal of the controller 2210 .

When the motor 2111 is rotated, the worm wheel gear 2112b meshed with the worm gear 2111a formed on the rotation shaft of the motor 2111 is rotated.

When the worm wheel gear 2112b is rotated, the spur gear rotating shaft 2112 fixedly coupled to the worm wheel gear 2112b is rotated, and accordingly, the spur gear 2112a fixedly coupled to both ends of the spur gear rotating shaft 2112 is also rotated.

When the spur gear 2112a is rotated, the sector gear 2121d of the module coupling part 2121 engaged with the spur gear 2112a is rotated, so the through hole 1210 formed in the module mounting protrusion 1200 of the module fixing frame 1000 is rotated. ), the module coupling part 2121 coupled to be relatively rotatably coupled through the module mounting projection connection hole 2121b of the module coupling unit 2121 rotates around the module mounting projection connection hole 2121b.

Therefore, the module fixed to the module mounting hole 2121a at the bottom of the module coupling part 2121 is rotated in the opposite direction to the sector gear 2121d.

When the module coupling part 2121 in which the sector gear 2121d meshed with the spur gear 2112a is rotated is rotated, the module fixing frame 1000 by the interlocking bar 2122 interlocked with all the coupling parts 2121. Since all the coupled module coupling units 2121 are interlocked and rotated, all modules (control module/light source module) coupled to each module coupling unit are interlocked and adjusted at the same angle.

Since the light emitted from the light source module 2200 is designed to have the most effective illuminance when irradiated vertically to the ground, it is preferable that the light source module 2200 be parallel to the ground.

However, when installing a street lamp, the light source module 2300 of the street lamp may not be level with the ground. However, if the operation mode is set to the automatic mode, the sensing of the gyro sensor 2220 of the control module 2200 installed in the street lamp head The control module 2210 is operated so that the control module 2200 in which the gyro sensor 2220 is disposed is horizontal with the ground, and when the control module 2200 is horizontally adjusted, all other light source modules 2300 are also operated by interlocking action. Of course, it is adjusted to be level with the ground.

On the other hand, when civil complaints due to light pollution occur, light pollution prevention is prioritized over illuminance efficiency. Adjust the angle of the light source module 2300 so as not to irradiate the residential facility (indoor) of

When the module angle is adjusted in manual mode, the outermost part of the light emitted from the street lamp head can be easily identified with the naked eye by the red light emitted from the laser unit 2230. Adjust the angle of the light source module 2300 to prevent light pollution can be done more easily.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and it is common in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims.
