Physics Lamps & Lights

Sunlit Perspective Lamp

Get one here (a few models to choose from):

From Amazon: BUY NOW: Backlit Perspective Lamp

Sunlit Perspective Lamp: when lit from behind this flat ink line-drawing jumps into 3D via perspective shading of sunlight and some color lithophane type images placed behind the sketched windows. A fun take on the power of geometric perspective to suggest three dimensions from two.

Color Enhanced Lithophane: Escher Dragon

Get a color lithiphane here: (the dragon or photo of your choice)

From Etsy: BUY NOW: 3D printed full color lithophane

Lithophane Color Escher Print: another modern take on the lithophane technique from the 1820s- this time with color changing LEDs and again via modern 3D printing that allows full color images through selective absorption and transmission of light. This lithophane was created using a photo of my black light poster (featured two posts back). Traditional lithophanes produced gray tone images by shining light through a translucent substance, initially porcelain, where thicker regions absorb the light and appear dark gray, and thinner regions look light gray. 3D printing allows a new method for producing this art form with amazing detail, where layers of colored plastic, applied in the right sequences and thicknesses, can produce lifelike and artistic results. Yet another amazing 3D print by Alex L. Kling!

The Kitty Cat Lamp I found: here

Kitty Cat Fireworks Lamp: illusion of depth from multiple refections. This glass cat sculpture is partially coated inside and out with a thin metal layer. The metal layer is made thinner in a pattern of small circles and stars to produce iridescent colors through thin-film interference effects. When lit from within by white LEDs, multiple reflections on the curved contour of the glass creates the firework like spray of light and color.

 


Lithophane Color Einstein Portrait

Lithophane Color Einstein Portrait: in celebration of the great physicist and his monumental discoveries this portrait is a modern take on the lithophane technique from the 1820s- but updated via modern 3D printing to produce full color images through selective absorption and transmission of light. Traditional lithophanes produced gray tone images by shining light through a translucent substance, initially porcelain, where thicker regions absorb the light and appear dark gray, and thinner regions look light gray. 3D printing allows a new method for producing this art form with amazing detail, where layers of colored plastic, applied in the right sequences and thicknesses, can produce lifelike and artistic results.

Levitating Sphere Lamp

From Amazon: BUY NOW: Levitation Lamp

Levitation Lamp: tapping the floating spherical magnet turns this LED lamp off and on in this interesting design. The magnet floats a couple centimeters from the surface of the base when plugged in, and feels springy to the touch. Within the base is a control system with adjustable electromagnet coils in a feedback loop with Hall effect sensors which allow for fine tuning of a magnetic field to precisely balance the pull of gravity.


Octogon Infinity Lamp

From EP Designlab: BUY NOW: Octogon Infinity Lamp
Special discount for @physicsfun followers on all EP Lights products

Octagon Infinity Lamp: parallel partially mirrored panes with multi colored LEDs create the illusion of depth through the physics of reflection and refraction. This design incorporates selectable programmed color shift patterns that add a dynamic motion component to the classic infinity mirror concept. 

RGB Lightpipe Bracelet

From Amazon: BUY NOW: Color Changing RGB Bracelet

Personalized bracelets avialable here: BUY NOW: Color Changing Personalized Bracelet

Get this diffraction grating here to explore light source spectra:
From Amazon: BUY NOW: 500 line/mm diffraction grating

Note: this site contains affiliate links for which I may be compensated

RGB Lightpipe Rave Bracelet: three LEDs (red, green,blue) combine to make an entire pallet of colors that are transmitted through the translucent band via internal reflection and refraction like a fiber optic cable. A diffraction grating reveals the variety of colors produced is simply a mixture of red, green, and blue (note that white = R+B+G), the same way pixels on your phone or laptop use RGB mixing to produce color images. The bracelet can be personalized and has a magnetic clasp- fun physics for your next rave! 

 


Vintage Bulb Spectra

Get this diffraction grating here: explore light source spectra! 

From Amazon: BUY NOW: 500 line/mm diffraction grating

Note: this site contains affiliate links for which I may be compensated

Vintage Bulb Spectra: emission line spectra identify the gas within these two vintage discharge glow bulbs- revealed here by a 500 line/mm diffraction grating. The color of each gas is due to a mix of the colors emitted from electron energy transitions specific to each element, the basis of spectroscopy.

Fluorescence of Lapis Lazuli 

Get a sphere and other polished samples of Lapis Lazili here:
From Etsy: BUY NOW: Lapis Lazuli

You will also want an awesome UV flashlight like this one:
From WayTooCool: BUY NOW: High Power UV Light (best UV products and service available)

Note: this site contains affiliate links for which I may be compensated

Fluorescence of Lapis Lazuli: A polished sphere of lapis lazuli, blue with the mineral lazurite, evokes the form of a banded planet with swaths and speckles of other minerals such as calcite, pyrite, sodalite, and hauynite. The beam of a long wave UV flashlight reveals an astonishing transformation of appearance where the banding on the sphere glows bright yellow via fluorescence of the hauynite inclusions. The colorful glow comes from complex quantum mechanical behavior where molecules of some of the minerals absorb high energy UV photons and then emit this energy out in the form of lower energy photons- the physics of fluorescence. 


Moravian Star Lamp

BUY NOW: Herrnhut Star Lamps

Moravian Star Lamp: recently I was traveling trough Munich where I discovered this beautiful geometric holiday decoration throughout the airport (swipe for photos). The star has 26 points with the geometry of a stellated rhombicuboctahedron which produces 8 triangular points and 18 square shaped points. Also called Herrnhut Stars these decorations have been a traditional part of the holidays for more than 160 years where the first stars where constructed by a mathematics instructor at a Moravian church boarding school as part of a geometry lesson.
