Introduction to the chandelier

A chandelier is a ceiling-mounted decorative light fixture with two or more arms that support a light source. Chandeliers are often ornate, with dozens of lamps and intricate arrays of glass or crystal that illuminate a room by refracting light. The following will introduce you to chandeliers.

The history of the chandelier

The earliest chandeliers began with the nobility in the Middle Ages, using candles for lighting. They usually feature a wooden cross that can hold candles at the tip, and the whole device can be hung to a suitable height with a string or hook.

After the beginning of the 15th century, more responsible designs began to be used, and the ring or crown shape became more popular, used in palaces, nobles, monks, and merchants. Lighting at night was expensive, and the crystal chandelier became a symbol of the wealthy. In the early 18th century, many crystal chandeliers in merchant-class homes had many curved arms and candles. Neoclassical motifs became an increasingly common element, mostly cast in metal, but also carved and gilded wood. The development of glass-making techniques in the 18th century brought down the price of hard crystals. The glass properties of this highly refractory light made crystal chandeliers quickly become a popular form.

In the 19th century, gas lamps became a popular lighting source, and ceiling chandeliers were produced. In the mid-19th century, gas chandeliers appeared, and a large number of candle chandeliers were converted into gas chandeliers. In 1890, electric lighting appeared, and the chandelier also adopted electric lighting. With the popularity of electricity and reliable supply, modern chandeliers became the standard.

The principle of the chandelier

Refraction, a common physical phenomenon, refers to the angular shift caused by a change in velocity when an object or wave is incident from one medium obliquely into another medium. That is the principle of the chandelier. "Refraction" must be equivalent to "refraction of light", so although light (a kind of transverse wave) will change the direction of light travel due to the difference of "refraction", the phenomenon of "refraction" cannot be used to prove that light is a wave.

The so-called "reflection", that is, "refraction of light", refers specifically to light from one medium to another medium with different refractive indices, or when the parts of the same medium with different refractive indices run, due to the change of the wave speed. It is also the principle of the crystal chandelier. The difference is the phenomenon of changing the direction of light travel. For example, when a wooden rod is inserted into the water, the naked eye will think that the wooden rod is bent when it enters the water. This is because the light is refracted when it enters the water, which brings this effect.
