Glowing edges LED installation

2020

This light artwork is shiny dark blue powder coated metal. The 2 mm lasered circles light up in yellow, green, blue, magenta, red and purple led-light. The work of art comes with a dimmer. The tilted shape of this luminous work symbolizes the tilt of the Earth (as a result, the sun is always perpendicular to the Earth on and between the tropics once a year and twice a year on the equator). The 11 glowing colored edges are geographic coordinates on Earth that are numerically captured.

Glowing Edges LED installation shows an abstract form of electromagnetic radiation (based on what we do see; RGB) that bends around the earth like a spiral (in 11 phases) due to the rotation of the earth around the sun, the speed of light and spacetime.

 

All of the energy from the sun that reaches the Earth arrives as solar radiation. Solar radiation includes radio waves, microwaves, infrared, red, green and blue rays (visible light), ultraviolet light, X-rays, gamma rays and cosmic rays. The visible radiation we know is RGB, which together makes white light, but the electromagnetic spectrum goes further than that and represents invisibility on both sides of the visible part. It varies from long waves with little energy to short waves with extremely high energy. The shorter waves such as ultraviolet B/C, X-rays, gamma rays and cosmic rays are blocked by the atmosphere.

 

This work comes together with a video and a QR-code that serves as a reference. The video shows this spiral as a path following 11 geographic coordinates, locations on Earth that are numerically captured on Google Earth at an altitude of 300 meters and navigates from the Tropic of Cancer through the equator to the Tropic of Capricorn. It starts in Saudi Arabia in the desert and ends in the Pacific Ocean in the water. The route is approximately 96000 km long.

 

The QR code shows internet images (free images of Pixabay and Wikimedia Commons and some reference pictures of Google Earth) in sequence of locations on this route. It shows, in a radius of 1000 km, the possible consequences of radiation power on Earth when the sun is perpendicular to the equator or the tropics. The continuously repetitive nature of perpendicular solar radiation, which is the most powerful, leaves its mark on the Earth. Electromagnetic radiation has different wavelengths and travels at the speed of light. The locations are affected differently.

From dusk till dawn LED installation

2019

This light artwork is white diffused acrylic with magenta fluorine colored acrylic on the back. The slowly looping gradient of color of 24 hours is animated by integrated computer-programmed LED lights. The shape of this luminous artwork varies from rectangle to square which symbolize the infinity of rays of light.

95x95x11 cm (or 195x95x11 cm / 145x95x11 cm)

 

From dusk till dawn LED installation simulates day and night and shows a 24 hours animated light between sunrise and sunset on the equator when the sun is perpendicular to the equator. This artwork comes together with a QR code which shows images (galapagosconservation.org.uk) of endemic animal species who lives all in harmony at The Galápagos Islands.

#0100ff - #ff0001 LED installation simulates extra-spectral colors like crimson, magenta, bright pink, and purple. These colors don’t correspond to a wavelength on the visible spectrum and are located between red and blue, between the hex color codes: #0100ff and #ff0001. This work of art comes together with a QR code which shows (internet) images of destruction of the Ring of Fire and the Fruit dove.

Black body LED installation

2019

Black body shows the color temperature of a light source for white light which is defined as the temperature of a hypothetical black body whose emitted light gives the same color impression as the light source and usually expressed in kelvin. For colors based on black-body theory, blue occurs at higher temperatures, whereas red occurs at lower temperatures. This is the opposite of the cultural associations attributed to colors, in which red is hot, and blue is cold, it is the color temperature of lamps which makes them visually warm, neutral or cool.

Eye of kingfisher

2018

Water-cut aluminium, powder coated midnight blue

210x150x0,3 cm + 1 cm distance from the wall

 

Eye of kingfisher is about the ever-changing light. While the sun (or the earth to the sun) revolves during day, drop shadow changes to different shades. In morning the shade is light gray and during the day it’s getting darker and darker. During civil twilight, when sun is up to 6 degrees below the horizon, the shade changes to a blue purplish hue. When the sun drops further to 12 degrees and the nautical twilight occurs, the drop shadow becomes dark gray. At astronomical twilight, when the geometric center of the sun is 18 degrees below the horizon, the shadow is almost black.

 

Remarkable about the kingfisher is that he prefers to live in shady areas, where he is not hindered by reflection of light when hunting. He has a predominantly blue color, with iridescent feathers on head and wings and his belly side is warm orange colored as if at certain times of the day in certain sunlight he can always look different for his prey.
