Project Description

From 28 September to 2 October 2022, Detlef Hartung and Georg Trenz are among the artists selected for the Gelsenkirchen light art project “Goldstücke”. In the centre of the Buer district, Goldberg Park and the neighbouring St. Mary’s Assumption Church will become a projection surface for texts and typographies entitled “Goldberg Variations”. The title itself is an allusion to the location in the city centre (Goldberg) as well as to the composition of the same name by Johann Sebastian Bach. However, Hartung and Trenz do not create a baroque, musical composition here, but rather vary terms and texts in a free, associative manner. The backdrop and canvas for the light projections is the place itself.
For the projection of the artwork, 12 units of the PHOS 85 outdoor projection systems from Derksen Lichttechnik are used, which are installed on the poles of the pathway lighting.
The digital data of the typography was transferred with a laser onto the projection templates in the projectors – technically known as “gobos”. Gobos function in a similar way to a slide, but are indefinitely durable and do not fade.
Thanks to modern LED technology and light-concentrating optics, the total power consumption of the 12 projection systems is approx. 960 watts, which is on a par with the consumption level of an electric kettle or upper-class gaming PC. By switching off the pathway lighting in the park, power consumption is further reduced.
