Abstract: Light indicator which comprises a support body to which multiple rows of LEDs and multiple lenses are fixed, each of which positioned in front of the corresponding row of LEDs, and provided with a rear surface directed towards the LEDs, and with a front surface directed in the sense opposite the aforesaid rear surface. In addition, the light indicator comprises multiple coupling bodies, each of which extended between two ends thereof, of which a rear end is engaged with the support body, and a front end is provided with a first bent portion engaged in abutment against the front surface of the corresponding lens in order to retain the latter integral with the support body itself.

Abstract: Apparatus for transporting a device along a tower, which comprises a rail susceptible of being fixed to a tower and extended according to a substantially rectilinear guide direction, and a trolley slidably constrained to the rail and adapted to support a device to be transported provided with at least one power cable. The rail comprises at least one hollow shaped profile with elongated form, which is longitudinally extended according to the guide direction between a lower edge thereof and an upper edge thereof, and is provided with an internal surface which defines a guide seat in which the trolley is slidably housed and in which the power cable of the device is susceptible to pass.

Abstract: Light indicator which comprises a support structure provided with multiple seats, each of which housing at its interior rows of LEDs and a power supply circuit providing electrical power supply to the LEDs. The light indicator also comprises collimation lenses each positioned in front of the corresponding row of LEDs, and an insulating material layer deposited in each seat to cover the power supply circuit. Each lens extends parallel to the corresponding row of LEDs, and on the rear part is provided with an abutment portion fixed on the base surface of the seat and provided with a rear groove housing the row of LEDs. The abutment portion of each lens is closed transversely and longitudinally by longitudinal and transverse walls defining a rear edge which adheres to the base surface of the seat in order to prevent the insulating material from penetrating into the rear groove.
