Photometer

The "Photometer" is an urban lighting unit. It allows the user to modulate the colour of the light source according to his wishes for a few seconds. 

Three (3) weights provide the possibility to adjust the color of the light. Each weight is responsible for the intensity of an independent coloured lamp. The colours used are as follows: red , green , blue. The synthesis of the three colours of the RGB scale is capable of creating any colour. 

The 'photometer' consists of three cylindrical parts of equal diameter, the 70 cm high base, the 160 cm high trunk, which also carries the main 'control', and the 70 cm high crown, in which the light source is integrated. The pole has a diameter of 20 cm, the final cross-section will depend on the needs of the construction. The material of the pole is proposed to be anodised aluminium. The absence of paint helps to restore the sabotage as from graffiti.

The operation of the "photometer" is based on an analogue electrical circuit for regulating the intensity of 3 light sources using a 10-turn dimmer. The "Photometer" has no electronic board and this makes it less vulnerable to time.
