Many inventions and discoveries are inspired by animals and plants. For example, the discovery of luminescence was inspired by fireflies.

Cold light was discovered by American scientist Boyle in17th century. When he was young, he caught many fireflies and put them in bottles. At night, he actually lit up the whole house. Boyle thinks, "Candles glow by air. What about fireflies? "

He pumped all the air out of the bottle, and sure enough, the light went out. As he expected, fireflies really glow by air. When he grew up, he conducted more in-depth research. Boyle imitated its luminous substance according to fireflies, and finally made it after many experiments. Because this light has no heat, it is called cold light.

Cold light was widely used later, which prevented our desk lamp from exploding when it burned to a certain extent, or it would hurt our hands when touching the lamp. Thanks to Boyle and fireflies.

Extended data

Fireflies glow for courtship. Fireflies glow as a signal of communication between men and women. Because most adults flying in the sky are males, females usually only crawl in the grass.

In addition, some females, such as terrestrial fireflies in Taiwan Province Province, fireflies in Taiwan Province Province and fireflies in Yunnan Province, even have completely different appearances from males. At this time, in order to woo, they will blink and send messages.

When fireflies are disturbed by foreign enemies, in order to drive them away, they will emit fierce light to scare them off and achieve the purpose of self-protection, especially in the larval stage.
