After reading these two innovative German lamps, you will understand the importance of learning physics

Lamps have always been one of the products that industrial designers are particularly keen on. Just look at the two most important events in the field of international lighting - the Milan International Lighting Fair and the Frankfurt Lighting Fair - to attract a large number of new and cutting-edge exhibits. If you look closely at these new products, you will find that most of them are still making a fuss about the appearance or material of the lamp holder and the lamp holder. It is still rare to touch the working principle of the lighting device.

The two lamps to be introduced today are not only from the hands of German designers who are known for their rigor, but also to some extent break the imagination of ordinary people.

No switch

This is the L3 table lamp from the rlon design studio in Berlin, Germany. At first glance, you may feel that this is probably an incredible art installation, or some kind of strange experimental equipment. Anyway, it is completely out of touch with the lamps. If someone tells you at this time, this is a desk lamp, please open it. After carefully reviewing the front, back, left and right, you will most often be surprised to ask: Where is the switch?

The mystery is on the "unexpected" metal ball on the solid wood base.

Originally, the surface of L3 solid wood seat has magnetic force. By using the principle of electromagnetic induction, as long as the metal ball moves forward and is placed in the center of the lamp, the table lamp is illuminated; otherwise, if the metal ball is removed, L3 is extinguished. The little metal ball, like the energy block of Transformers, controls the light and darkness of the fixture.

The designer hopes to deepen the interaction between the user and the product through this unusual switching method, and feel the change of symmetry and tension, divide and conquer and combine in the push and pull.

No Light Bulb

Although the innovation of L3 is amazing enough, it still has a light tube. The Guise series of lamps designed by The German designer Stefan Diez and the Spanish lighting brand VIBIA, which abandoned the traditional bulbs/tubes as the light source. When you turn off the lights, you can only see a fully transparent tubular or round shape glass.

When the switch is turned on, the light will scatter light and bright light from the edges of the glass or the fine grid lines, but you can't understand where these mysterious lights come from.

Guise's working principle is not esoteric, even in middle school physics class - Total Internal Reflection (TIR).

|Total internal reflection, also known as total reflection, is an optical phenomenon. When light enters a medium of lower refractive index from a medium of higher refractive index, if the incident angle is greater than a certain critical angle θc, the refracted ray will disappear and all incident ray will be reflected without entering the low refractive index medium.

In order to achieve the desired refraction effect, the designer has carried out optical reflection experiments on special paper products, PVC, glass fiber, glass and other materials. Among them, high-quality pure glass is the best effect material.

In the Guise series of lamps, the light source is actually hidden in that thin black line. The light emitted by the LED grating will pass directly through the glass body until it encounters a pattern or edge, which will form a halo effect.

After reading these two designs, I just want to say:

Innovation is an important step in human progress and social development. Please respect innovation and encourage innovation. At the same time, we must also maintain the outstanding achievements of innovators, so that we can have a virtuous circle and let new technologies benefit more people.
